The vacuum circuit breaker should undergo an annual power outage inspection and maintenance to ensure normal operation.

The Vacem VCKG AC high-voltage vacuum contactor series is suitable for power systems with rated AC 50Hz, working voltage of 6kV~10kV, and working current of 160A~630A. High voltage vacuum contactor is a high-voltage control electrical appliance, it provides remote control and frequent operation of electrical equipment such as high-voltage motors, power transformers, capacitors, etc, in the power system. Contactors are widely used because they have a series of advantages such as long service life, frequent operation, small size, light weight, no explosion, no pollution, low price, convenient maintenance, and good breaking performance. The structure of the contactor is simple and clear, there is an incoming copper plate on the upper side and an outgoing copper plate on the lower side, ensuring installation, maintenance, and reliability. Our article contains: ​The main structure of vacuum contactors; Precautions for using vacuum contactors; ​Applications and maintenance of vacuum contactor;

Vacuum circuit breakers are famous for its high vacuum in both the arc extinguishing medium and the insulation medium in the contact gap after arc extinguishing; having the advantages of small size, light weight, suitable for frequent operation and extinguish arc without maintenance. It is widely used in distribution networks. Vacuum circuit breakers are indoor distribution devices in a 3 to 10kV, 50Hz three-phase AC system. It can be as the protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations. Especially suitable for use in places that require oil free, minimal maintenance, and frequent operation. Circuit breakers can be configured in central cabinets, double-layer cabinets, and fixed cabinets for controlling and protecting high-voltage electrical equipment. Our article includes: The main structure of vacuum circuit breakers; The working principle of vacuum circuit breaker; The application of vacuum circuit breakers; The functions of vacuum circuit breakers; The characteristics of vacuum circuit breakers; The specification standards for vacuum circuit breakers; The advantages of the vacuum circuit breakers.
