SNV500seires intelligent dividing control system of Vacuum circuit breaker   

1.  System description

    The system is designed for demarcation and isolation protection of outdoor distribution network with rated voltage of 12 kV and three-phase AC of 50 Hz. Through Intelligent Vacuum Circuit Breaker Switch and intelligent switch control terminal running of the linkage intelligent control，then In order to realize and achieve  the automatic switching-on and closing action of the circuit breaker controlled by the switch control terminal when the load circuit has inter-phase short-circuit fault, phase-to-ground fault, or when the circuit is overloaded, so as to realize the disconnection and isolation of the faulty branch lines without affecting the operation of the whole power grid, thus playing the role of demarcation protection of the power grid. It is mainly used for switching off and closing load current, overload current and short circuit current in power system. It is suitable for protection and control in power distribution system of substations and industrial and mining enterprises, and more suitable for countryside power grids and frequently operated places.
