Outdoor H.V. gas live tank 400 kv circuit breaker

1.Brief Introduction

H.V. A.C.porcelain type SF6 gas circuit breakers, with voltage from 40.5-550kV and rated current up to 4000A, manufactured by our company, are provided with

three kinds of operating mechanism, pneumatic, spring and hydraulic type.

Motor is used in spring mechanism to charge closing spring and charge opening spring at closing. Disk spring is used in hydraulic mechanism to be charged instead

of traditional compressed nitrogen gas for charge, and hydraulic driving is used at both opening and closing. Compressed air is used in pneumatic mechanism as driven

force for open while spring is used for close. The three kinds of operating mechanisms have their own features and are used in circuit breakers of different voltage

class respectively.Due to the unit structure in circuit breaker, there are advantages of minimized number of breaks,lower number of parts, simple structure,high

reliability and long period of inspection.
