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.

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: Recently went out to do the test, do not know the difference between the two tests
- Preventive testing is to test or test equipment periodically and regularly. For example, once a month, 3 months or a few times a year of preventive testing or testing, to exclude the existence of hidden dangers...
- Q: Electric power automation equipment
- Construction and transformation of rural power grids, power plants, power plants, environmental protection, automatic control and integrated automation of nuclear power plants, technical management, etc..
- 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: 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: What equipment is necessary on the list of electrical engineering equipment?
- Take 35KV power engineering, the need for ZGF-400kV/2mA DC high voltage generator
- 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.?
- At least the national research institutions to do, here is about not a conclusion. If such a conclusion, it also belongs to the commercial classified data, not just to show people.
- Q: The cost calculation of power equipment
- The cost of your equipment maintenance is calculated according to the method of replacement and maintenance
- Q: What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
- High frequency means high frequency, the rated frequency of the power system is 50Hz, the maximum range of 49.8~50.2Hz, under normal circumstances, the power dispatching department will be developed through the power generation plan
- Q: Ask the expert about the design of the power system diagram, 6kV side of the electrical equipment how to supply
- 6kV equipment directly in the 6kV bus out of the lead, do not consider the capacity, it does not affect the use of 380V equipment
- Q: The state of power system equipment is divided into four states
- (1) running state. The isolating switch and circuit breaker of the equipment are in the closing state, and the circuit is connected between the power supply and the receiving end.(2) hot standby. The circuit breaker of the equipment is disconnected, and the isolating switch is in the closing state. (3) cold standby. The circuit breakers and disconnecting switches of the equipment are in the open position.
