HGW9-12KV through isolation switch
An overview of the isolation switch:
High pressure isolating switch is important in a power plant and substation electrical system switch electric appliances, with the high voltage circuit breaker, its main function is to: ensure high-voltage electrical appliances and equipment in the safety of repair work, ACTS as the isolation voltage, can't use and cut off,
The input load current and the open circuit current can be used only for certain switching operations that do not produce a powerful arc.
Isolation switch structure:
The commonly used high voltage isolating switch mainly includes the following parts: the conduction part, the insulation part, the transmission part, the base part.
Isolation switches for use:
High voltage isolation switch points outdoor and indoor, outdoor type including single switch and three pole isolator, commonly used for the open circuit isolating switch power supply circuit is separated from the user; The indoor type is often connected with the high voltage circuit breaker to ensure the reliability of the power failure. In addition, in the high voltage complete distribution device, the isolation switch is commonly used as a voltage transformer, lightning arrester, power transformer and measuring tank for high voltage control.
Production technology of high voltage isolating switch:
The GW9 series isolation switch is divided into: 200A, 400A and 630A.
There is also a hucheng style, common type for customers to choose. Base plate hot galvanization, connection bolt and other standard parts are stainless steel
