Product Description

Rooq-24kv 2500A Vcb Vacuum Breaker VS1 Indoor Vacuum Breaker 

Product Description

VS1 indoor medium voltage Vacuum Circuit Breaker is a three-phase AC 50Hz ,rated voltage 6KV,12KV,24KV switch equipment of power system.

Breaker adopts the integral design of the actuating mechanism and the breaker body, which can be used as a fixed installation unit or as an individual VCB carriage together with handcart. They have a long life expectancy. There is no adverse effect on the vacuum, even from frequent switching of operating and short-circuit currents.

Advantages

VS1 type VCB consist of operating mechanism and arc-extinguish chambers in front-back arrangement, its main conductive circuit is floor model structure. The vacuum arc-extinguish chamber is fixed in a vertical cannular insulation column made of epoxy resin by APG technology, therefore with high anti-creepage function. Such structure design greatly reduces the accumulation of dusts on the surface of vacuum arc- extinguish chamber, it not only can prevent the vacuum extinguish chamber from outside influences, but also can ensure to present high resistance state against the voltage effect even in warm-wet climate or heavy pollution environment.

1 - with reliable interlock functions, suitable for frequent operation
2 - low noise and energy consumed
3 - simple and robust construction.
4 - high operating reliability
5 - mechanical durability of switch : 20000 times, etc
 
Fields of application

1 - Transformers and distribution substations
2 - Generator control and protection
3 - Capacitor bank control and protection, etc
