In distribution systems technique of neutral ground is usually categorized into neutral unground, neutral ground via resistor, and neutral-point grounding via arc suppression coil. Differnent grounding ways decide various operating ways. With development of economy , over-head line which is the main way of past power grid has been replaced by cable running line. Meanwhile, some new equipments such as hermetic compact structure of SF6 swichgear, twisted polyethylene cable and zinc oxide arrester are more and more widely applied. Therefore, non-effective grounding technique is unsuitable to present situation. As a result, to set neutral point grounding effectively is the important facet of power supply we should work on.
If neutral grounding resistance cabinet is installed, the current flowing through grounding point and neutral point would be much lower than that when metallicity grounding. Therefore, adopting neutral grounding via resistance could decrease transient overvoltage when single-phase grounding, and eliminate arc flash hazards like transient overvoltage and some resonant overvoltage associated with the first ground fault, and moreover it could adopt relays to quickly locate the fault circuit and clear it up.
Mingrui has outstanding technical researching team and superior equipments, specially concentrate on research & development, production, sales and service of neutral grounding series products of power distribution system. The transformer neutral grounding resistance cabinet we developed and produced is applicable to 6~35KV power distribution grid of cable running lines in cities, large industrial enterprises, factories, airports, seaports, subway and etc. as well as 0.66KV system in mine digging and 0.4kv/6kv/10kv system in power plants.
- Q: On the nameplate of the electrical equipment, what does ith UE ie mean?
- UE subscript is rated voltage, rated current, rated power,Ith is a heating current,Ui insulation voltage
- Q: Reactive power compensation methods commonly used in power equipment
- The centralized compensation is to set up the reactive power compensation device in the power distribution room to compensate the reactive power in the region. Due to the introduction of several kinds of compensation sampling is set at the point of measurement, so you can minimize the interest rate generated electricity.In the professional field and transmission line compensation (high and low), furnace low-pressure grid compensation, flameproof compensation device etc..
- Q: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator
- The equipment you have listed has this function. The generator and the camera belong to the rotation compensation equipment
- Q: Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines
- Power equipment including: boiler, steam turbine, pump, deaerator, condenser, generator and so on, from the impact of steam boiler turbine blade hot out of the turns, then drives the generator to rotate to generate electricity, in general, now in thermal power plant and a large Shipping Co to use steam turbine
- Q: In order to obtain the qualification test of power equipment, the company needs to have a hard condition
- The provincial electricity supervisor application; can only apply for five (10KV and below) or level Four (35KV and below) qualification, the first level of qualification can only apply for the first four to rise
- Q: What is the meaning of the station control layer in the power system
- The process layer is an intelligent primary equipment in the exponential transformer substation, such as the intelligent terminal of the intelligent circuit breaker which is not yet fully developed, and the merging unit of the electronic transformer
- Q: The difference between electric load and power supply capacity
- Power consumption / power consumption of electric equipment used for electric power load.Power supply capacity of the power supply system, generally refers to the user step-down transformer capacity, such as how many kva.
- Q: What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the situation,
- Automatic control and other means to achieve power generation and load demand power balance. In the event of an accident, the balance can not be controlled by these means
- 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.
- 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.
