Description

 outdoor high voltage vacuum circuit breaker

Overview About high voltage vacuum circuit breaker

high voltage vacuum circuit breaker. ZW20-12 outdoor AC HV vacuum boundary circuit breaker (hereinafter referred to as the boundary circuit breaker) is one of our new products. Boundary circuit breaker is a multifunctional intelligent device with the function of vacuum breaker,vacuum load switch, recloser, sectionalizer four switches.

The main configuration consists of vacuum breaker, CH-40 controller, external voltage transformer (Note: distribution automation line ring network available in bilateral PT) three parts. Products are widely used in 10kV, 13kV city, rural power grid space ring network for disconnecting switch, contact switch, automatic switch device which can implement the ring deployment line load.

It can be used as boundary switch (commonly known as watchdog) in the branch line of power supply, used as reclosers and sectionalizers in feed overhead distribution network. Boundary circuit breaker with remotemanagement pattern, protection and control functions and communication functions.

Reliable detection in judgment, mA level zero sequence current and shortcircuit current between phases, realize the automatic removal of single-phase grounding fault and phase to phase short circuit fault.

The main switch is vacuum arc and insulation adopts SF6, N2 mixed gas. The case introducting of Japan, Germany, French gas sealing, explosion proof, insulation system technology, the overall excellent sealing performance.

Inside is filled with SF6, N2 mixed gas which does not leak, not affected by the external environment. The spring operating mechanism with miniaturization and performance optimization design, action reliability is much higher than the traditional spring mechanism.
