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 principles should be followed in power equipment maintenance
- (2) the maintenance plan shall be arranged according to the unified arrangement of the power grid to improve the coordination and reduce the outage time of the equipment,. Improve operation reliability and equipment availability.
- Q:What are the relevant national standards for power equipment?
- GB/T10228-2008 GB/T50062-2008 GB/T11032-2000 GB 11032-2010 DL/T613-1997 GB/T17468-1998 GB/T17468-2008 GB/T17211－1998 DL/T804-2002
- Q:The insulation level of the electrical equipment in the neutral grounding system shall be consideredA. phase voltage;The square root of 2 phase voltage B.;The square root of 3 phase voltage C..Great God in the end this election? I am very tangled!
- For example, 220kV transformer (YNYnd11) insulation level high voltage side is LI950AC395-LI400AC200, the front half part (head) of the lightning impulse voltage and power frequency withstand voltage were significantly higher than that of the second part (neutral side). According to the power frequency withstand voltage needs to achieve 1.6 times the rated voltage requirements, the first end of the line voltage is considered in accordance with 220kV, the neutral point according to the phase voltage (127kV) considerations. But there are some places are fully insulated, that is, according to the line voltage calculation.The triangle connection must be considered by the line voltage. Overall, C is definitely right.
- Q:Withstand voltage test, power equipment insulation unqualified reasons?
- Voltage test, power equipment insulation failure may be due to: insulation deterioration. Such as transformer oil into the water, solid insulation moisture, insulation aging, etc., will lead to decreased insulation performance, in the pressure test may not be qualified.
- Q:Hello, I would like to ask what are the main rotating equipment in the power system? What is a rotating device?
- Generators, motors, blowers, air conditioning, transportation, lifting, etc.. Rotating machinery can be called rotating equipment
- Q:In what way is it confirmed that the destroyer is an electrical device? Identification or what.
- The behavior of the power line that has been installed and has not yet been powered off shall be treated differently. If the stolen cut is not formally delivered to the power sector to use the line, should be handled in accordance with the theft case. If the actor knows the line has been delivered to the use of the power sector and steal cut wires, shall be designated as the crime of destruction of power equipment.
- Q:The two devices of the power system have those
- Internal equipment:1, measuring meter, such as voltmeter, ammeter, power meter, electric energy meter for measuring electrical parameters in the circuit.2, insulation monitoring device.3, control and signal device.
- Q:What is the redundancy of electrical equipment
- Disk duplex: a I/O controller is added to the mirrored disk to form a dual disk to improve bus contention.RAID: cheap redundant array of disks (Redundant array of inexpensive disks). As the name suggests, it consists of a number of disks, through a controller to coordinate the movement of a single data flow into the disk. The RAID3 system consists of 5 disks, in which 4 disks store data, and the 1 stores the check information. If a disk fails, you can replace the disk on the line, and through the other 3 disks and check the disk to re create the data on the new site. RAID5 will check the information distributed on 5 disks, so you can replace any disk, the rest with the same RAID3.
- Q:How to run a company that operates electric equipment
- Or do not do other electric power equipment, but the company's other power products to pull the business on the line, at the beginning of the sale to the quality of good, and then the price is low, a long time there is profit, customers will have.
- Q:The state of power system equipment is divided into four states
- Several types of equipment in power system:Power system equipment is generally in operation, hot standby, cold standby and overhaul four states
