switch

Shenyang Yi Feng Electric Co., Ltd., founded in 2008 focused on the development, production and sales of electric energy saving products. Provide high performance capacitors for power industry. Provide solutions to improve the power factor for the industrial enterprises, to save energy, improve the utilization rate of the power distribution system.

Have from the beginning until the core production of vacuum coating, after testing, Italy, company can set automatic production line. Production of cylindrical capacitor, is the only one single capacitor current to do 100A manufacturers. And in the cylindrical type of mine heat furnace compensation capacitor, 10KV line compensation for circular capacitor in the domestic leading level.

 ZK series intelligent switch is fill switch (ZK-50-1) and separate compensation switch (ZK-50-2), total compensation switch for switching capacitor, using a triangle connection method; separate compensation switch is used for switching single-phase capacitor and the Y-shaped connection. The intelligent switch selects the intelligent switching module, the suction arc module and the mechanical switch parallel operation, which has the advantages of the arc extinguishing in the moment and the breaking off. Intelligent switch with significant advantages of no impact, low power, longevity of service, alternative contactor and thyristor switch. It is widely used in low-voltage reactive power compensation, but also can be used as the substitute for AC contactor.

2 functional characteristics

You no switching arc;

It is low power consumption, without external heat sink;

To the input signal and the main power supply, can be directly matched with the reactive power compensation controller;

It has a switch status indicator, the capacitor is switched on, the light;

To switch off automatically when power system, power supply, normal, automatic recovery work;

It has strong anti-interference ability.
