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: What is the installation equipment of the transformer on the power installation project
- Installation of lightning arresterMost of the external factors that affect the operation of distribution transformers are from lightning accidents. Therefore, the transformer equipped with lightning protection devices, should be used in the synthesis of metal oxide arrester without gap insulation, the power frequency voltage withstand capability, good sealing, protection characteristics.
- 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.
- Q: What are the necessary equipment for power line project?
- There are connection tools, such as hydraulic pliers, crimping pliers, pressing tools, connecting tube, detonation pressure tube; the last is a measuring device, theodolite, rod, etc. in addition to the measuring rod; excavation tools such as shovels, iron, hammer and so on.
- Q: I would like to set up a power engineering Co., Ltd., do not need to know what the scope of business
- Do not need to be able to do anything! Or you can hang on to someone else's qualifications!
- Q: Electrical equipment classification
- Current carrying conductor and gas insulated equipment. Such as bus, power cable, insulator, wall bushingA device that limits over current or over voltage, such as current limiting reactors, surge arresters, etc.Transformer equipment: make a circuit of the high voltage and large current is reduced, for measuring and relay protection devices, such as the voltage and current transformer protection in order to ensure the normal operation of an electrical equipment, the operation status monitoring, measurement, control and adjustment of the equipment is called two electrical equipment. There are a variety of measuring meter, a variety of relay protection and automatic devices, DC power equipment, etc..
- Q: Reactive power compensation methods commonly used in power equipment
- Hello!Electrical equipment commonly used in reactive power compensation and the method of improving power factor are: synchronous motor, synchro, series capacitor compensation, shunt capacitor and series reactor compensation (EHV transmission line) and SVC, SVG compensation. SVG is through the power electronic device IGBT and its control circuit, a active VaR of equal amplitude and opposite to the size of the system, the reactive power compensation device for reactive power compensation to offset the system in recent years is the development direction of reactive power compensation.
- 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: What is the meaning of the station control layer in the power system
- Through a new layer, control layer mainly refers to the monitoring of plant level, for example in the substation monitoring system, sub station system. The station control layer equipment mainly refers to the monitoring station, engineer station, sub station information and so on. The spacer layer mainly refers to the relay protection and control, recording.
- Q: What are the two devices in the power system
- Your question is somewhat ambiguous, as I understand the following: the two equipment is a device for the work of the control, protection, monitoring and measurement equipment
- Q: Power equipment is required to replace the dimension, the state has no relevant provisions
- But more time has entrusted operation maintenance experience unit maintenance, power equipment to customers is good, one can improve the safe and stable operation of equipment, to meet the demand of a power supply section, on the other hand it can guarantee and increase operation life of equipment.
