How Does Hall Sensor Work?
DC current hall sensor is a magnetic field sensor made according to the Hall effect. It has two working modes, open loop (straight) and closed loop (magnetically balanced). The advantages of the direct-release Hall sensor are that the circuit form is simple and the cost is relatively low; its disadvantages are poor accuracy and linearity, slow response time and large temperature drift. In order to overcome its shortcomings, closed-loop (magnetically balanced) Hall current sensors have appeared.

Ⅱ. Use and installation standards of 3-phase electric meters

A 3 phase power transducer is a relatively complex meter, generally used in large factories and shopping malls and other facilities. Because of the large amount of electricity that needs to be metered, the accuracy of the meter is very important. How to use a 3-phase electric meter?

1. The meter has been inspected and sealed before leaving the factory, and it can be installed and used. If there is no lead seal or it has been stored for a long time, the relevant department should be re-calibrated and sealed before installation and use.

2. The 3-phase programmable power meter should be installed vertically and not inclined in a dry and ventilated place. The bottom plate on which the meter is installed should be fixed on a wall that is sturdy and fire-resistant and not easy to vibrate. The height of the meter is about 1.8m.

3. Connect according to the wiring diagram, tighten the wiring screws, and fasten the connecting plate in the lower end of the twist box.

4. The actual number of electric energy is obtained by multiplying the indicated number of the electric meter connected by the transformer by the transformation ratio.

5. One form and one card: The IC card held by the user cannot be exchanged. If it is lost, it should go to the power supply department (ie the electricity sales office) to purchase a replacement.

What Are the Classifications of AC Current Sensors?(2022年)

acrel2022 — 2022-12-15T18:15:10+0900

https://www.acrel.gr/products/data-center-monitor/

Ⅰ. AC current sensors classified according to the induction principle

1. Electromagnetic split current transformer

Electromagnetic current transformer is a special transformer, referred to as current transformer. Under normal use conditions, the secondary current is substantially proportional to the primary current, and the phase difference is close to zero when the connection method is correct. Secondary windings are used for measuring instruments, meters, relays and other similar electrical appliances.

2. Hall current sensor

Hall current sensors are based on the Hall effect principle, including open-loop Hall current sensors and closed-loop Hall current sensors. Closed-loop Hall current sensors are also called zero-flux current sensors or magnetic balance current sensors.

3. Rogowski coil

Rogowski coil, also known as Rogowski coil, is an AC current transducer. It is a hollow annular coil. It has two types: flexible and rigid. It can be directly placed on the conductor to be measured to measure AC current. Rogowski coils are suitable for the measurement of AC current in a wide frequency range. There are no special requirements for conductor size, and they have fast instantaneous response capabilities. They are widely used in current measurement devices where traditional current measurement devices such as current transformers cannot be used. measurements, especially high-frequency, high-current measurements.

Ⅱ. AC current sensors classified by output signal

1. Analog output AC current sensor

Most current sensors in engineering applications are analog output AC current sensors. The advantage of the analog output current sensor is that the interface is simple, and the secondary instrument is easy to standardize.

2. Digital output AC current sensor

It is more reasonable to convert the measured parameters into digital parameters because the analog output requirements for traditional analog output transmitters are based on limited conventional technology, not based on the actual needs of the equipment using the measured parameter information. The digital output AC current sensor can use optical fiber transmission, and the digital output AC current sensor with optical fiber transmission can completely avoid the loss and interference of the transmission link, and is suitable for high-precision measurement in complex electromagnetic environments.

Ⅲ. AC current sensors classified by signal frequency

1. Power frequency current sensor

Due to the nonlinear characteristics of the iron core, the electromagnetic current transformer is mainly suitable for the current measurement of the rated frequency. When the frequency is too high, the output current will be distorted, and when the frequency is too low, the transformer may be saturated and damaged. It is generally suitable for power frequency current measurement with small harmonic content.

2. Frequency conversion current sensor

Electromagnetic current transformers are mainly used for the measurement and measurement of power frequency current and electric energy. Hall current sensors are mainly used for industrial control and independent voltage and current measurement. Therefore, the angular difference index, which is closely related to the accuracy of power measurement, is generally not nominal. Therefore, it is not suitable for high-precision power measurement.

With the development of frequency conversion technology and energy saving technology, it is necessary to accurately evaluate the energy efficiency of various frequency conversion speed control devices, while electromagnetic voltage and current transformers generally can only accurately measure the power of power frequency sinusoidal circuits. The new frequency conversion power AC current transducer is a combined voltage and current sensor. This type of sensor directly outputs digital quantities and uses optical fiber for transmission, which can effectively avoid loss and interference in the transmission link. And it has small ratio difference and angular difference in a wide frequency range, and can accurately measure various types of variable frequency electricity (voltage, current, power and harmonics, etc.). It is suitable for product inspection and energy efficiency evaluation of hybrid electric vehicles, electric vehicles, solar power generation, wind power generation, inverters, inverter motors and fuel cells.

Under the New Situation, How to Prevent Fires in New Energy Electrical Appliances?(2022年)

acrel2022 — 2022-12-15T18:14:34+0900

https://www.acrel.gr/products/isolated-power-systems/

In the context of sustainable development, the impact of new energy on social production at this stage is becoming more and more obvious, but the frequent occurrence of new energy electrical fires has become an important factor restricting the further development of new energy. This paper focuses on analyzing the related issues of new energy electrical fire prevention and new energy vehicle fire control ideas under the new situation, hoping to be helpful to the work of relevant personnel.

Ⅰ. Causes of new energy electrical fires

Internal equipment failure will lead to fire in new energy devices. From a technical point of view, due to the high technology content, there are often a large number of groups inside, and there are many interfaces between groups, which determines the new energy The probability of equipment failure increases. For example, many new energy equipment needs to be filled with lubricating oil, and due to the large number of interfaces, the lubricating oil inside the new energy equipment is easy to seep through the interface; at the same time, some equipment itself has quality problems, such as poor sealing effect and careless assembly. etc., will also lead to oil leakage. After the equipment between groups is soaked in lubricating oil, some parts will be damaged, which will lead to fire; the existence of thermal insulation sponge inside the electrical equipment, or oil pollution in the hydraulic system, etc., will aggravate the spread of the fire. A fire can cause huge losses.

Incorrect electrical installation will also become a cause of fire. As mentioned above, new energy device has a high technical content, so its installation is significantly more difficult than conventional energy electrical equipment. Therefore, during the installation of electrical equipment, because the construction personnel The technical errors and improper installation of the electrical equipment will lead to a series of problems such as poor contact and grounding faults during the operation of the electrical equipment, resulting in rapid changes in the temperature inside the electrical equipment, which will eventually cause a fire. At the same time, if there is a quality problem in the selection of the overload protection device of the new energy device, the unmatched overload protection device will be installed inside the electrical equipment, which will eventually lead to a fire in the electrical equipment.

Ⅱ. How to deal with new energy electrical fires?

1. Re-education of fire knowledge for all personnel is also an effective method to control new energy electrical fires, so that relevant personnel can be orderly in the face of fires, avoid fire losses from expanding, and even control fires in the bud. The main contents of fire education work include:

(1) Identification of fire sources. It is necessary to educate relevant personnel according to the actual situation of new energy devices, and explain the types of fires that may occur, such as the fires caused by lightning strikes, the fires caused by internal faults, etc. discrepancies and should therefore be noted by the staff.

(2) Let employees master the skills of fire handling. After a fire occurs, the disposal of on-site personnel becomes the key to controlling the development of the fire. Therefore, in fire education, it is necessary to let employees master the small skills of fire handling, such as how to use the fire extinguisher correctly, and if necessary, contact the local fire department. Hold fire drills to further deepen employees' understanding of fire control methods.

(3)Ensure that the charging facilities and equipment used in the motorcycle sheds and parking spaces of the community are regular products. At the same time, do a good job of publicity, and do not buy some cheap batteries without warranty.
(4)

At a time when controlling greenhouse gas emissions and actively addressing climate change has become a global consensus, "green, low-carbon and sustainable development" has become the common goal of social and economic development in all countries in the world. At present, 127 countries around the world have made "carbon neutrality" commitments. On September 22, 2020, my country proposed at the United Nations General Assembly that carbon dioxide emissions should peak by 2030, and strive to achieve "carbon neutrality" by 2060.

1. China's energy consumption is relatively high

In recent years, driven by the strong "new economy", my country's IDC business revenue has achieved continuous rapid growth, with an annual scale of 223.87 billion yuan in 2020, a year-on-year increase of 43.3%. Corresponding to the expansion of the data center industry, in the past 10 years, the overall power consumption of my country's data centers has increased rapidly at a rate of over 10% per year. In 2018, the total power consumption of data centers nationwide was 150 billion kwh, reaching 2.19% of the total social power consumption. It is expected that by 2025, the proportion will double to 4.05%, and data centers have become large energy consumers.

Data centers not only consume a large amount of energy, but also have a high level of energy consumption. According to the data released by the China Internet Data Center: In 2019, the market size of my country's data centers reached 156.1 billion yuan. In the same year, the total power consumption of my country's data centers reached 176.3 billion kWh, and the average energy consumption level of the entire data center industry was as high as 11,294 kW. _hour/10,000 yuan operating income, equivalent to 3.614 tons of standard coal/10,000 yuan operating income (converted at 320 grams of standard coal/kWh). In 2019, my country's steel industry leader: Baowu Group's comprehensive energy consumption per 10,000 yuan of output value is only 1.4 tons of standard coal/10,000 yuan. Although there may be some deviations in terms of statistical caliber and data sources, there is no doubt that the data center industry is characterized by high energy consumption.

2. The path to data centers and "carbon neutrality"

Achieving "carbon neutrality" in a data center is a systematic project, and how to maximize the development and utilization of clean and renewable electricity on the power supply side of the data center is particularly critical.

The power consumption side mainly includes the energy consumption of IT equipment, the energy consumption of air conditioners, and the energy consumption of the building itself. Various energy and environmental protection technologies should be integrated to reduce the energy consumption of the power consumption side. The overall technical development direction should be: improve the energy efficiency of equipment, adapt to the characteristics of clean and renewable power supply, and maximize the use of cold energy resources.

3. Energy efficiency monitoring solutions provided by Acrel

AMC Series Data Center Monitor Module is an intelligent system designed for the end of the data room, which can comprehensively collect all energy data, and provide accurate electrical parameter information for AC and DC power distribution cabinets. In addition, it can upload data to the dynamic environment monitoring system through communication, realize real-time monitoring and effective management of the entire data room, and provide a reliable guarantee for the realization of all-round green IDC.

First of all, the "carbon neutral" data center development model based on clean and renewable energy is the ultimate model for data center development, so that the development of the data center industry can get rid of the current passive situation. Second, as the price of clean, renewable electricity continues to fall, the economic viability of “carbon-neutral” data center development will become increasingly complete. Thirdly, the construction and operation of "carbon neutral" data centers are based on a new energy technology system. It is necessary to systematically integrate clean energy technology, refrigeration and cold energy utilization technology, energy storage technology, flexible power supply technology, etc. It is also necessary to make full use of power trading, carbon trading and other means as well as data center business model innovation. Finally, the development of "carbon neutral" data centers urgently needs the support and guidance of national policies, and the proportion of green electricity usage should be used as the evaluation standard for data centers, rather than the PUE value.

Breakthrough In Power System Management: Current And Voltage Sensors For Operational Safety
The condition of the power system is very closely related to the national economy and social development. The operation efficiency of power system is highly valued by the country. With the development and progress of science and technology, the power system is becoming more and more complex and the safety requirements are getting higher and higher, so there is an urgent need to develop new and efficient current, voltage and power detection technology equipment to ensure the safety of power system operation.

Traditional Current Sensor Principle And Shortcomings

Traditional current sensors include transformers, Hall sensors, fiber optic grating sensors, etc.. They can use different principles to detect current, each for different situations, and have limitations in terms of convenience.

The transformer is limited by its own electromagnetic induction principle, which can only measure alternating currents, but not DC currents. Moreover, ordinary transformers are generally only suitable for measuring 50 Hz sine waveforms.

Hall sensors use the Hall effect and the magnetic balance feedback principle to measure arbitrary waveforms of current and voltage, and can also measure the more important transient peaks in power systems. However, closed-loop Hall current sensors require a polymagnetic loop.

Fiber grating sensors are suitable for measurements in ultra-high voltage, strong electromagnetic interference and other operating environments. Fiber grating belongs to a narrow band filter. Fiber grating sensors incorporate fiber grating technology into the orbital circuit, but these sensors need to wrap the fiber around the conductor being measured.

Encore Intelligent High-Precision Non-Contact Current And Voltage Sensors To Ensure The Safe Operation Of Power Systems

Power system safety testing is critical and relies on accurate and efficient sensor technology equipment. Visionary high-tech companies have begun to develop and produce more efficient, accurate and convenient sensor technology equipment to ensure the safety of power systems and energy facilities.

The series of power sensor developed and produced by Encore Intelligence are based on Ampere's Law and use ultra-high-precision micro-magnetic based sensors with independent intellectual property rights to measure the magnetic field strength of wires, cables, rails, and other conductive bodies due to current, and then obtain their current values. It does not need the closed-loop Hall current sensor's poly magnetic ring, nor does it need to wrap the optical fiber around the measured conductor like the fiber optic current sensor, so it is extremely convenient to install and use, which truly realizes the non-contact real-time online measurement of AC and DC currents.

At the same time, Ancray Smart series non-contact current sensors combined with series of non-contact voltage sensors, can measure the power on the line and determine its direction. At present, Ancray Smart can provide mA-level, A-level, kA-level, analog and digital, voltage, current, power and other specifications of products, measurement accuracy of 0.1% or more. AC current sensor and voltage sensors can be used individually or through CAN bus networking, providing a new choice for the domestic 30-billion-dollar current and voltage testing instrumentation market and further meeting the needs of smart grid and power equipment development.

Ankerys intelligent series of current and voltage sensors can be used in many fields, including high-voltage wire inspection systems, power supply system overload protection systems, smart grid power management and real-time monitoring systems, high-power industrial electrical equipment control and safety protection systems. Specifically can be applied to batteries, photovoltaic batteries, electric vehicle charging piles, motors, inverters, power transformers, new energy vehicles, photovoltaic inverters, wind power, fans, pumps, rail transportation, naval integrated power and power propulsion, aviation power supply and other high-precision detection, but also as a variable frequency power measurement verification device current measurement reference.

https://www.acrel.gr/microgrid-energy-management-system-solutions/

Realization Of Dynamic Compensation Of Reactive Power

Asynchronous motors, induction furnaces and large-capacity rectifier equipment in the distribution system can be inductive in operation, requiring a large amount of reactive power, which increases the power loss on the power supply line and reduces the voltage quality, while the reactive current also reduces the effective utilization rate of power generation, transmission and supply equipment. The static reactive power generator can follow the change of load reactive power and realize the dynamic compensation of reactive power, so that the line loss is reduced to the lower limit and the utilization rate of generation, transmission and power supply equipment is fully improved.

Effective Maintenance Of Load-Side Voltage

For the load center, due to the large capacity of the load and the lack of large reactive power support, it is easy to cause low voltage or even voltage collapse problem accidents. The fast reactive power adjustment function of Ankorui's static reactive power generator device can effectively maintain the load-side voltage and improve the voltage stability of the power supply system.

Improve Line Transmission Capacity

The installation of static reactive power generators at the midpoint of long-distance transmission lines not only compensates the reactive power of the line in normal conditions, but also provides timely and rapid reactive power regulation in case of system faults, damping system oscillations and improving transmission system stability, thus effectively increasing the transmission capacity of the line.

Simultaneous Management Of A Variety Of Common Power Quality Problems

Ankerys' static var generator device can simultaneously manage many common power quality problems in the distribution network, such as three-phase imbalance, voltage flicker and power factor overrun, improving the quality of power supply to the network, ensuring safe and reliable operation of customer equipment, reducing energy consumption and improving efficiency.
