25.8kV Circuit breaker for gas insulated switchgear of 25.8kV class with improved insulation cooling function

摘要

More particularly, the present invention relates to a circuit breaker for a gas insulated switchgear of 25.8 kV or more in which an insulated gas cooling function is improved. More specifically, And more particularly to a breaker for a gas insulated switchgear of 25.8 kV or more, which is improved in insulation gas cooling function by maximizing the breaking performance by providing a means capable of cooling properly so as not to lower the breaking efficiency of the breakdown current.
