MRD-XHZ/XHP Arc Suppression Coil

Function

Arc suppression coils are used for capacitive current compensation during earth faults in electric networks. They are to be connected between the transformer neutral point and the ground.

Range

Adjust range:0~100% rated current
Voltage range: 6~66KV
Duration time: 2 hours Max.

Test & Quality

All Mingrui arc suppression coil are designed, rated, manufactured and tested in strict compliance with IEEC60076-6. Routine tests performed on each arc suppression coil are insulation resistance test,winding resistance measurement, applied voltage test, transformer oil withstanding voltage test and HV characteristic test. Mingrui’s internal quality system has been developed and certified under ISO 9001 quality system

Arc Suppression coil

1.MRD-XHZ step type: with tap changer
   connecting with different taps on ASC to
   change the inductive current with steps
2.MRD-XHP sliding type: change inductive
   smoothly by arranging a magnetized iron
   core inside ASC and applying DC
   magnetizing current on the iron core

Controller

1.IPC system, multilayer PCB, stable system operation
2.Color LCD with data display, set and query function
3.Auto measure system voltage and displacement voltage etc, Auto   
   trace and compensate
4.Compensate range: 0~100% of rated current
5.Inside inserted grounding fault detector and the fault feeder could
   be detected and switched off quickly
6.RS232 & RS485 communication interface
7.with standard printing interface and print timely and grounding
   information
8.Grounding wave is recorded and could display on any other
   computer without driver installation
9.Max. 1000 grounding information could be stored

On-load Tap Changer

Only needed if MRD-XHZ step arc suppression coil is chose.

Damping Resistor
Only suitable for MRD-XHZ step type, made of stainless steel alloy.
During earth fault, it is switched off, and during normal operation, it is connected with arc suppression coil to prevent resonant over-voltage

Optional

-Grounding transformer
-Shunt Resistor

 

Q: What is the GIS in power system
Popularly speaking, GIS is often we can see the switch station, also known as high-voltage distribution device.There are three types of high voltage power distribution equipment: the first is the conventional air distribution equipment, referred to as AIS. The bus bar is exposed directly to the air, and the breaker can be provided with a porcelain column or a tank type. This type is used in Gezhouba Dam power plant.
Q: Is the GIS in the electric power high voltage switch cabinet
IS is a shorthand for two conceptsThe 1 is the geographic information system.2 refers to the (GAS INSULATED SWITCHGEAR) gas insulated fully enclosed combination of electrical appliances, closed inside the main circuit breaker, isolation switch, grounding switch, bus, lightning arrester, etc.. Many power plants, substations, switching stations are made of GIS, so that the small footprint, or maintenance. With the high voltage switch cabinet or not.
Q: What is the installation equipment of the transformer on the power installation project
Installation of drop fuseHigh and low voltage side of distribution transformer should be equipped with fuse. High voltage side fuse at the bottom of the vertical distance from the ground is not less than 4.5m, the fuse and the horizontal distance of not less than 0.5m, in order to smooth down the fuse tube is easy to operate and fuse, axis drop type fuse with the vertical line of 15% ~ 30% angle. The vertical distance to the surface of the bottom of the low voltage side fuse shall not be less than 3.5m, and the horizontal distance of each fuse shall not be less than 0.2m.
Q: On the nameplate of the electrical equipment, what does ith UE ie mean?
Electrical equipment consists of two parts: power supply and power equipment. The power supply comprises a storage battery, a generator and a regulator thereof. The utility model comprises a starting system of an engine, an illumination, a signal, an instrument, etc., and also comprises an ignition system of the engine.
Q: How to strengthen the management of electric power information communication equipment
Problems in the management of information communication equipment1 personnel structure is not reasonable. With the continuous expansion of the power grid, power information communication equipment is also increasing. But at present, there are some problems in the management of electric power communication equipment, such as the lack of professional staff and the lack of post. At the same time, due to the lack of post phenomenon, resulting in the equipment management and maintenance work in the process of increasing the workload, making the existing staff complaints, work quality and work enthusiasm can not be guaranteed. On the other hand, because the new staff less power communication professionals confidence aging trend is more and more serious, the personnel structure imbalance restricts the progress and development of electric power information and communication equipment management to a great extent.
Q: What are the customer groups faced by power intelligent equipment?Products such as electric capacitor reactive power control (capacitor module), reactive power compensation controller, the series of electric power meter, active filtering equipment, power monitoring system, energy management system, operating system and DC power system accessory products.
If the capacitor is connected in series on the line, the line reactance is compensated and the parameters of the circuit are changed. Series compensation can reduce the loss of line voltage, improve the terminal voltage level, reduce the power loss and power loss, and improve the transmission capability.4 power capacitors include phase shifting capacitors, electric heating capacitors, voltage equalizing capacitors, coupling capacitors, pulse capacitors, etc.. Phase shifting capacitor is mainly used for compensating reactive power to improve the power factor of the system; the electrothermal capacitor is used to improve the power factor of intermediate frequency power system; equalizing capacitor in parallel with the general circuit breaker on fracture pressure; coupling capacitor is mainly used in electric power communication, measurement, control and protection of transmission line the capacitor is used for pulse; pulse circuit and DC high voltage rectifier filter.
Q: Reactive power compensation methods commonly used in power equipment
Hello!Electrical equipment commonly used in reactive power compensation and the method of improving power factor are: synchronous motor, synchro, series capacitor compensation, shunt capacitor and series reactor compensation (EHV transmission line) and SVC, SVG compensation. SVG is through the power electronic device IGBT and its control circuit, a active VaR of equal amplitude and opposite to the size of the system, the reactive power compensation device for reactive power compensation to offset the system in recent years is the development direction of reactive power compensation.
Q: What are the effects of frequency variation on power users and power systems?
As we all know, the asynchronous motor is widely used in industry. Its speed and output power are related to frequency. Changes in frequency, speed and power output of the motor is also changing, which seriously affected the quality of the product; modern industry, national defense and scientific research has been widely used in various electronic technology equipment, if the system frequency instability, affect the accuracy of these devices will be.
Q: Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
A device with a motor can be called a rotating device. Power system mainly refers to the generator, motor
Q: For example, EPS emergency power supply and so on, as well as those used in public emergencies.
High / low voltage switchgear, power distribution cabinets, industrial ovens, constant temperature and humidity test box, ovens, air curtain machine (invisible door), inductive automatic door, air conditioning and industrial fans, NELL thyristor module, thyristor, single / three-phase bridge rectifier, fast recovery module
