The role of switchgear

The object of the relay protection device

△ High-voltage switchgear

△ The relay protection device is generally installed on the high-voltage switchgear as a component of the high-voltage switchgear

 

The role of switchgear

● When using high-voltage power transmission, due to the high voltage level, an arc will be generated when a line with a load is disconnected;

△ Vacuum arc extinguishing——vacuum circuit breaker, generally used at 10KV

                       And the following voltage levels

△ SF6 arc extinguishing——SF6 circuit breaker, generally used in 35KV

                        Above voltage level

△ Oil circuit breaker-more oil circuit breaker, less oil circuit breaker.

The volume is huge, and the use of insulating oil as an arc extinguishing medium is easy to fire, has poor safety, and has a large amount of repair and maintenance work. It is basically eliminated at present.
