Overview
Outdoor high voltage vacuum circuit breaker is a outdoor distribution equipment with AC 50HZ,rated voltage 12KV and three-phase ac. It is mainly used for open circuit power distribution network and close the load current, overload current, short circuit current in power system.It is suitable for the transformer substation and factory power distribution system for protection and control use. Especially suitable for urban power grid and rural power grids.

Our Advantages
(1). Energy conservation: Farady voltage regulating type capacitors will change the output reactive power by regulating voltage on capacitors, so that the reactive power can be adjusted smoothly. Comparing with other method, it can ensure the capacitors in best condition, the energy saving effect is much better
(2). Low cost:If the old power transformer substation need to reform, only need to add a voltage regulator between the circuit breaker and capacitors, the original circuit breakers, reactors, capacitors can be reuse, greatly reduce the cost of transformation
(3). Maintance Free:When traditional circuit breaker and contactor switching, switching devices and capacitors often damaged because of the above problems, result in high maintenance costs, using Farady devices, automatic control reactive power output, there is no potential risks of other equipments, greatly reducing maintenance and staff costs in power transformer substation
