Vacuum breaker power transmission and distribution systems as the most common switch electrical equipment

Vacuum breaker power transmission and distribution systems as the most common switch electrical equipment, its mechanical  electric transformer  is necessary, but also improve the supply and distribution reliability, the only way to protect the safety of the power system. The overall design of the mechanical properties of the vacuum circuit  Voltage stabilizer  of the system mainly refers to mechanical actuation device driven dynamic and static contact points closing process, some of the performance indicators, the main trip contact stroke of closing speed, average speed of closing , open and close time, over the same period of the three-phase tripping, closing contacts average speed, closing contact bounce time, the cumulative movement allowed to wear contacts thickness.
