1,Brief Introduction to Product
MRD-FD type neutral ground resistor cabinet is complete equipment specially used by generators in power plant which adopts high-resistance grounding for neutral. The voltage grade for generator mainly ranges from 6kv to 20kv. When one point of the stator grounds, the device is able to limit the grounding current at a reasonable value, and effectively restraint arc flash transient overvoltage associated with single-phase grounding.
1,Applies to indoors.
2,Ambient temperature: between -40 and +40 centigrade.
3,The altitude shall not exceed 3000m.
4,Relative humidity be or lower than 95%(25 centigrade)
5,Power grid frequency:58-62Hz (60Hz System), 48-52Hz (50Hz System)

2.1 Parameters of Grounding Transformer
Insulation class：H
Cooling：AN
Protection Level: for paper-insulated dry type grounding transformer, the PI is divided into IP00 (no enclosure), IP20, and IP23 (with enclosure) .
Insulation level, impedance voltage on-load loss and no-load loss are according to relevant national standards.
Insulation resistance testing: high voltage-low voltage and to earth≥300MΩ，and low voltage-earth≥100MΩ.
- Q:What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
- That response to the power parameters is high frequency, this requires high cycle splitting device, tripping the corresponding circuit breaker, to remove the part of power grid connected or separated from the original into two or more power, get rid of the accident or the narrow scope of the accident to
- Q:Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
- For 35/6KV step-down stationEach line with the 6/0.4KV transformer, or 6KV equipment (such as 6KV synchronous motor), are the load of the stationSo, there are 6KV devices, single occupancy 6KV bus on a certain line can be
- 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:I would like to ask the power experts, according to the annual additional electricity, installed capacity, how to calculate the amount of the necessary supporting power equipment, etc.?
- The question you asked is too big, it belongs to the category of power planning
- Q:Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator
- Other static compensation equipment. The utility model relates to a capacitor and a reactor, which belongs to a device for absorbing reactive power
- Q:No concentrator can be copied directly
- Centralized meter reading. Power system is an important part of power automation system, and it is an intelligent system which develops rapidly in recent years. The system integrates data acquisition (JY-RTU6640), intelligent control and network communication, and realizes remote data exchange and real-time monitoring. Through the centralized meter reading for power users, improve the accuracy, reliability and safety of meter reading work; can realize the real-time calculation of line loss; to detect anomalies and the phenomenon of stealing electricity meter; effective control of electricity arrears behavior; reduce the cost of management, so as to improve the modern management level of power marketing.
- Q:Power test equipment sales to find power supply company which departments? Which departments of the power supply company will use the power test equipment?
- The need to find a maintenance work area (a place called SF6, fix test area) switch belongs to them
- Q:The state of power system equipment is divided into four states
- (4) maintenance status. Circuit breaker and isolating switch device in the open position, the circuit breaker can be divided, and the control switch, fuse (or switch) switch maintenance should be off line and on both sides of the grounding switch (or installed ground), and hung signs work.
- Q:How to run a company that operates electric equipment
- First to find a company to do the power equipment, their prices, of course, the ex factory price to come over
- Q:What is the specific name of the double name of the equipment in the electric work sheet? Know please enlighten me.It would be better if you had a sample ticket.
- The double name of equipment refers to the name and number of the equipment.The name of the equipment is Chinese, the number is Arabia. Together is a double name. The same station, will not appear the same name, or the same number, is the only. The only combination of the two can be more accurate.
