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: Power equipment are 10KV or less, there is a business license, will be issued by the electrical installation (repair, test) power facilities license five and above qualifications, you do not need a safety production license ah? Urgently needed: Power installation qualification certificate: one, two, level threeLevel 1: mechanical and electrical equipment installation engineering contract one class or the transmission and substation engineering contract qualification of an independent legal person to build more than 220 thousand volt classTwo level: mechanical and electrical equipment installation engineering contract two class or transmission and substation engineering contract qualification of independent legal person (220kV and below the transmission line, the construction of the substation) twoThree level: mechanical and electrical equipment installation engineering professional contract three level or transmission and substation engineering professional contract level three qualification of independent legal person (110kV and below transmission line, substation (room) construction)

Q: 1, what are the fire hazards caused by electricity in the server room?2 what are the fire hazards in the server room?: Five, fire control room and electrical fire monitoring detector set over 8 independent electricFire monitoring detector six, electrical fire monitoring system settings should affect the power supply 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: The production and transportation process of electric power: The transmission of electric energy, which is connected with the transformer, distribution and electricity, constitutes the whole function of the power system. Through the transmission, the far apart (up to several thousand meters) linked to the power plant and the load center, the development of electricity and use beyond the geographical restrictions. Transmission and other energy sources (such as coal, oil etc.) compared to transmission loss, high efficiency, flexible and convenient, easy to control, less environmental pollution; transmission can also connect the power plant in different locations, implementing peak and valley regulation. Transmission is an important embodiment of the superiority of the use of electric energy. In modern society, it is an important energy source.

Q: Electric power automation equipment: Power grid dispatching automation, power system analysis and control, power electronics, power market, distribution automation,

Q: Private enterprises must be free transfer of power facilities: 1, belonging to the public nature of the public utility lines or occupy the planning corridor, by the unified management of power supply enterprises. The power supply enterprise shall reach an agreement on the operation, maintenance and management of power supply facilities prior to the handover. The power supply enterprise shall retain the capacity of the original owner in the above-mentioned agreement for the public power supply facilities for unified operation and maintenance management.2, belonging to the nature of the user, but not in the public substation power supply facilities, by the user operation and maintenance management. If the user operation and maintenance management is indeed difficult, with the power supply enterprises to negotiate, commissioned on behalf of the power supply enterprise operation and maintenance management matters related to the signing of the agreement.3, belong to the user sharing nature of the power supply facilities, by the owner of the property rights of common operation and maintenance management. If the user has difficulty in running and maintaining management, it can negotiate with the power supply enterprise to sign the agreement on behalf of the power supply enterprise on behalf of the operation and maintenance management.

Q: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator: The power supply in the power system is a three-phase sine alternating current generated by the generator, in which there are two kinds of electric power.

Q: Withstand voltage test, power equipment insulation unqualified reasons?: Test methods and voltage measurement methods are not correct. For example, when the transformer is tested, the non - Test winding is not connected to the ground, and the non - tested winding may be discharged to the ground. For example, the test of large capacity test, the voltage is still on the low side of the measurement, due to the capacitive effect, the actual increase in the voltage on the test sample over the test voltage, resulting in the breakdown of the subject matter, misjudgment is not qualified.

Q: For example, EPS emergency power supply and so on, as well as those used in public emergencies.: The latest electric power emergency response and emergency plan for safety protection"Emergency treatment and safe latest power accident contingency plans to protect the implementation of manual" is based on the country's electricity production safety accident emergency system master, provides all levels of power supervision departments and the major power companies, power system, power grid to cope with major public emergencies working principle, organization system and operation mechanism, for guiding the competent departments and local governments at all levels in various industries and departments effectively deal with the power of public emergencies, protect public life and property safety, has an important role to reduce disaster losses.
