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 With development of economy , over-head line which is the main way of past power grid has been replaced by cable running line.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: No concentrator can be copied directly
- There are two types of remote meter reading devices in electric power generation: one is low voltage set, called concentrator, the other is called terminal. The concentrator role is the number of meter data, first by the carrier or 485 communication way to collect the equipment, and then through the cable (optical fiber) or wireless network (cdma/gprs) transmitted to the main station.
- Q: What is the LCP cabinet of electric power equipment
- Local control cabinetLocal control cabinet installed in the work site, which is likely to have PLC, the scope of the control cabinet than PLC wide
- Q: I would like to open a company on the construction of power equipment, what needs to be prepared? (including qualification level, capital requirements, etc.) the more detailed the better
- The second is the power facilities installation, repair and testing qualification. Also divided into one to four, respectively, by the State Electricity Regulatory Commission, power supervision bureau and the city in the county, the county's dispatched office - to do the examination and approval of the electricity office. In some places there may be five, is designed for the establishment of the company.As for the size of the funds, different levels of economic development, the requirements are different, only to the location of the business sector consulting.In the actual participation in bidding and other construction activities, be sure to carefully read the tender documents and other construction projects, different projects for different requirements of different qualifications.
- Q: Generator, shunt capacitorShunt reactorShunt capacitorStatic compensator
- The power supply in the power system is a three-phase sine alternating current generated by the generator, in which there are two kinds of electric power.
- Q: What specific enterprises and units are used to test the power of the equipment ah
- Electric Power Bureau must be used to detect classes, each project must be checked by the Electricity Industry Bureau
- Q: Power equipment Market Overview
- The first quarter of 2013, China's economic growth rate has declined, but overall still maintained at a high level, especially the power equipment of power transmission equipment and electrical equipment demand remains steady growth, thereby stimulating imports of the rapid growth of the industry; at the same time, the world economy has been warmer, the international power equipment market demand a modest recovery, I pull the power equipment China's manufacturing exports continued to grow. In the import and export growth driven by two, the first quarter of China's total import and export of electric power equipment manufacturing industry rebounded significantly.
- Q: The two devices of the power system have those
- Internal equipment:1, measuring meter, such as voltmeter, ammeter, power meter, electric energy meter for measuring electrical parameters in the circuit.2, insulation monitoring device.3, control and signal device.
- Q: What is the power plant
- Is to do the preparation of electricity ahTransformer transformerSmall to power switch, etc.
- Q: The cost calculation of power equipment
- These costs are based on the situation at the scene, for example: 1 your losses exceed the standards of the power supply bureau, will be fine
- Q: Pre checking and checking of goods in power system
- That is one of the effective means to ensure the safe operation of electrical equipment. Over the years, the power sector and power equipment of large industrial and mining enterprises are basically in accordance with the rules of the preventive test of power equipment issued by former Ministry of electric power "(hereinafter referred to as the" Regulations ") requirements for testing, the timely detection and diagnosis equipment defects play an important role.
