Abstract :
To develop a compact three-phase encapsulated gas circuit breaker (GCB), particular consideration must be given to the mechanical and electrical effects of electromagnetic force and hot gas between poles, which are characteristic of the three-phase encapsulated structure, in addition to efforts to make a compact interrupting chamber and minimize driving energy. Employing an interrupting chamber with a novel concept, and after investigating and proof-testing important items, a 145 kV /40 kA GCB was developed for gas insulated switchgear application
