Information

It is mainly used for the control and protection of power system (including power plants, transmission and distribution lines, industrial and mining enterprises and other users). It can not only put a part of power equipment or lines into or out of operation according to the needs of power grid operation, but also quickly cut off the fault part from the power grid in case of power equipment or line failure, so as to ensure the normal operation of the fault free part in the power grid, equipment and operation safety of maintenance personnel. As a superior product category exported by our company, power medium and high voltage equipment is widely exported to Central Asia, Southeast Asia, Europe and America, etc. It mainly includes the following categories:

 

Oil immersed power transformer - this kind of product is suitable for AC 50 (60) Hz. Three phase maximum rated capacity is 2500kVA (single phase maximum rated capacity is 833kva, single-phase transformers are generally not recommended). it can be used indoors (outside) when the ambient temperature is not higher than 40℃, not lower than -25℃, the maximum daily average temperature is 30℃, the maximum annual average temperature is 20℃, and the relative humidity is not more than 90% (environment Temperature 25℃), the altitude does not exceed 1000m. It can also be installed on the pole when the capacity is 315KVA and below.

Distribution transformer refers to a kind of static electrical appliance used in distribution system to transfer AC energy by changing AC voltage and current according to electromagnetic induction law. Chinese transformer products can be generally divided into UHV (750kV and above), UHV (500kV) transformers, 220-110kv transformers, 35kV and below transformers according to the voltage level. Distribution transformer usually refers to the power transformer running in the distribution network with the voltage level of 10-35kV and the capacity of 6300KVA and below, which supplies power directly to the end users.

Dry type transformer is widely used in local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and other places. In short, dry type transformer refers to those whose core and winding are not immersed in insulating oil.

Isolating switch-- mainly used for "isolating power supply, switching operation, connecting and cutting off small current circuit", without arc extinguishing function.

Lightning arrester - an electrical appliance used to protect electrical equipment from high transient overvoltage when lightning strikes, and to limit the time and amplitude of the continuous current. Arresters are sometimes called over-voltage protectors, over-voltage limiters.
