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 With development of economy , over-head line which is the main way of past power grid has been replaced by cable running line.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:I would like to set up a power engineering Co., Ltd., do not need to know what the scope of business

- Q:On the safety hazards of electric equipment safety
- 4 where the demolition, the power line protection zones of overweight, lifting, drilling, piling, scaffolding and other construction work, it shall be permitted by the power supply departments, take appropriate safety measures, and can work in the power supply department under the supervision of professional staff.5 prohibit the installation of electric power facilities within the range of 500 meters to carry out blasting operations, fireworks, etc..6 prohibit fishing in the power line protection zone, in case of personal electric shock accident.7 ban on power line protection zones, such as various types of debris piled hay straw, especially prohibit piling flammable and explosive materials.
- Q:What is the amount of equipment used? Higher profits? Do you have any power generation companies in China?
- National grid examination review will find it difficult to integrate the knowledge of many aspects of the examination, the topic is also miscellaneous, the total can not touch the law. So before the exam on the long manager to accompany the class library to do it again, the test is not so difficult to finish feeling.
- Q:Part of the rated voltage of the power equipment is marked 10.5kv, and this is similar to the label 10KV power equipment what is the difference?Consulted a lot of teachers, but it is said that this is the old and new two methods, I would like to ask what is the basis of this, it is best to have a national standard for reference
- 3, rated voltage transformerRegulations, to accept the power of the primary winding, the output power of the two windings, the general, the primary winding voltage = network voltage, the voltage of the two winding due to the consideration of the loss, higher than the network voltage of 5% to 10%
- Q:Electric power equipment includes what steam turbines are used in what areas of what companies need steam turbines
- The main power equipment including power equipment and power supply equipment two categories, power generation equipment is the main power plant boiler, steam turbine, gas turbine, turbine, generator, transformer, power supply equipment is the main transmission line, voltage transformer, contactor etc..The steam turbine is the power equipment, except for the thermal power plant and central heating power station, is also used to drive other equipment, large fan and water pump, ship steel plant, such as large enterprises, pharmaceutical chemical screw compressor etc..Steam turbine and thermal power stations are generally used as the main steam turbine companies, followed by a wide range of applications in pharmaceutical, chemical, metallurgical, petrochemical enterprises.
- Q:What are the effects of frequency variation on power users and power systems?
- Power frequency: generally refers to the frequency of electricity market, China's power industry, the standard frequency of 50 hz. Some countries or regions, such as the United States, are set at 60 hz.
- Q:The company has a number of power equipment to be exported, need to go through the sea, the technical requirements of three, I would like to ask what is the three here? How to check whether the complete sets of components used to do three treatment? Please exhibitions, grateful!
- Three refers to the anti moisture, salt spray, anti mildew.According to the complete set of electrical as well as five: (1) to prevent the wrong points, close circuit breaker;2) to prevent the pull and load isolation switch;3) to prevent the electrification (hanging) grounding switch (line);4) to prevent the ground wire (switch) with circuit breaker (isolation switch);5) to prevent straying into the charged interval.
- Q:What specific enterprises and units are used to test the power of the equipment ah
- Electrical installation company, has installed for repair, test qualification. The test is power detection.
- Q:All I know is a generator, a transformer. I also want to fully understand the power system related to the equipment, from power generation to end users (enterprises, factories, they will design the equipment, production equipment is not to say, but they will be transferred to the electricity, in use is the processing equipment, such as transformer, I only know this involved) equipment, detailed list, thank you ah
- Divided into primary equipment and two equipmentOnce the equipment is responsible for the transmission of electrical energy, the two equipment is responsible for monitoring and protection of primary equipment.
- Q:What is the meaning of the high - voltage high - voltage device in power system, which is mainly used to protect the equipment and equipment
- High voltage means high voltage, similar to the above. Alternating current has active power and reactive power, the frequency response is the balance of active power, and the voltage response is reactive power balance
