FAQ
Q:What is the benefit of using a vacuum contactor?
A:
In conclusion, medium-voltage vacuum contactors are specialized electrical switches designed for medium-voltage power systems. They utilize vacuum interrupters to extinguish arcs when contacts are opened or closed. These contractors offer advantages such as enhanced safety, longevity, and low maintenance.
Q:What is the principle of vacuum contactor?
A:
The vacuum contactor is mainly composed of a vacuum interrupter and an operating mechanism. The vacuum interrupter has two functions of reliable arc extinguishing when passing the normal operating current and frequently switching the operating current. But it cannot cut off the overload and short-circuit current.
