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

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:The two devices of the power system have those
- 4, relay protection and automatic devices, such as relays, automatic devices, used to monitor the operation of a system, rapid response to abnormal and accident, and then acts on the circuit breaker, protection control.5, DC power supply equipment, such as storage batteries, DC generators, silicon rectifier, etc., to provide control and protection of DC power supply and DC load and emergency lighting, etc..6, high frequency wave blocking device.7, since the cast device.
- Q:The production and transportation process of electric power
- Transmission lines can be divided into overhead transmission lines and underground transmission lines according to the structure. The former is composed of line tower, conductor, insulator and so on, which is erected on the ground; the latter is mainly used for laying underground cable (or underwater). According to the nature of the current, the transmission can be divided into DC and AC transmission. In 1880s, the first successful realization of DC transmission, due to the low voltage limit (the transmission capacity is roughly proportional to the square of the transmission voltage) in the end of nineteenth Century for AC transmission replaced. AC transmission success ushered in the era of electrification in twentieth Century. Since 1960s, because of the development of power electronics technology, DC transmission has a new development, and AC transmission, with the formation of AC and DC hybrid power system.
- Q:No concentrator can be copied directly
- Although no concentrator can directly meter reading, but reading efficiency, cost and data integrity rate and data sharing will be greatly affected, so the power metersreading general will use concentrators or negative control terminal equipment.
- Q:Electrical equipment classification
- Mainly there:Equipment for the production and conversion of electrical energy, such as generators, motors, transformers, etc.;Switch on or off circuit breaker, such as circuit breaker, isolating switch, contactor, fuse, etc.
- Q:In power system, the general conditions for the selection of electrical equipment are
- Rated conditions, such as voltage and current, thermal stability, dynamic stability check, the most basic
- Q:Rivers and lakes emergency, there is a 110kV and 10kV power supply line works, I would like to ask this kind of power project warranty items, scope, life and other detailed provisions where can be found? Are there relevant regulations? For example, if the provisions of the housing construction warranty, you can check the "construction quality management regulations," but the warranty content of power projects, what information should be checked? Note that the warranty is not repair. Waiting for good people reply, satisfaction and then points.
- According to the "construction quality management regulations," the fortieth: the scope of the warranty and its normal use of the corresponding minimum warranty period of 2 years.
- Q:The relationship between primary equipment and two equipment in power system
- The two device is a device for the control, regulation, protection and monitoring of a device, which comprises a control device, a relay protection and automatic device, a measuring instrument, a signal device, etc.. The two device obtains the electrical connection with the primary device through a voltage transformer and a current transformer.
- Q:What is the definition of abnormal equipment, equipment failure, equipment failure and equipment accident? From which power standard?
- Obstacles: not clear, probably not normal and must be modified to be normal,If the circuit breaker parameter is not appropriate, change the parameter specification.
- Q:Withstand voltage test, power equipment insulation unqualified reasons?
- Without proper consideration of the atmospheric conditions that affect the insulation characteristics. Because of the pressure, temperature and humidity have a certain impact on the spark discharge voltage and breakdown voltage, without considering these factors may lead to equipment failure.
- Q:Power equipment Market Overview
- The first quarter of 2013, China's economic growth rate has declined, but overall still maintained at a high level, especially the power equipment of power transmission equipment and electrical equipment demand remains steady growth, thereby stimulating imports of the rapid growth of the industry; at the same time, the world economy has been warmer, the international power equipment market demand a modest recovery, I pull the power equipment China's manufacturing exports continued to grow. In the import and export growth driven by two, the first quarter of China's total import and export of electric power equipment manufacturing industry rebounded significantly.
