The HD series capacitor switching switch is designed specifically for reactive power compensation of 0.4KV power capacitors. This switch is mainly used for switching capacitors for power compensation in 400V voltage systems. And by combining power electronic switch thyristors with high-power bistable magnetic holding relays, voltage zero crossing input and current zero crossing cutoff can be achieved. It has the advantages of low contact resistance, impact resistance, reliable operation, low energy consumption, and long mechanical life. Mainly applicable for low-voltage reactive power compensation in factories, residential areas, transformer substations, urban and rural power grid renovation.
