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 With development of economy , over-head line which is the main way of past power grid has been replaced by cable running line.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:What equipment are used in the power, can help to divide some of the details, as well as the type of equipment under the type of equipment
Power equipment classification:1 the sequence of electric power in power system can be divided intoPower generating equipment, power generation equipment, power transmission equipment and electric equipment2 the main role of the power system can be divided intoPrimary equipment, two equipment
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 power plant
Are you going to apply for technical workers or Gang Gang ah, technology is the design of scientific research work what, workers do more
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: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
In addition to the requirements of industrial and commercial registration, there are two industry qualification requirements. Both are the higher the level, the higher the level of examination and approval department, the highest level, respectively, need to be approved by the State Ministry of housing and national home appliances. The newly established enterprises with no performance can only start from the lowest level four.
Q:What is the redundancy of electrical equipment
Disk duplex: a I/O controller is added to the mirrored disk to form a dual disk to improve bus contention.RAID: cheap redundant array of disks (Redundant array of inexpensive disks). As the name suggests, it consists of a number of disks, through a controller to coordinate the movement of a single data flow into the disk. The RAID3 system consists of 5 disks, in which 4 disks store data, and the 1 stores the check information. If a disk fails, you can replace the disk on the line, and through the other 3 disks and check the disk to re create the data on the new site. RAID5 will check the information distributed on 5 disks, so you can replace any disk, the rest with the same RAID3.
Q:Power equipment sales process, the customer asked the most questions thank you
3, the component parts of the device, which is the core component of the device, to master the working principle of the device oh;4, after-sales service problems, technical introduction of after-sales service;5, price, product prices and other brand products at what level;
Q:In what way is it confirmed that the destroyer is an electrical device? Identification or what.
Not yet installed agricultural low-voltage lighting circuit, not in the use of electrical equipment. Even if the person who took part in the erection of the wire, it will not cause harm to public safety, its behavior should be qualitative theft.
Q:What are the technical measures to ensure the safety of the power line equipment?
1 blackout.2 electrical inspection.3 grounding wire.4 use personal security line.
Q:1 what is the power system and the power network? 2 what is the rated voltage of the electrical equipment? Why do the power system to use a variety of voltage levels? 3
Power system is a kind of electric power production and consumption industry chain, which is from generation to generation. When the "power system" as an industry name, it includes power generation, for (transmission) electricity, power construction, power design, power test, power scheduling, etc..
