High-voltage vacuum circuit breaker is a circuit breaker that uses vacuum as insulation and arc extinguishing. Its components are: vacuum interrupter, operating mechanism (there are electromagnetic operating mechanism and spring operating mechanism), brackets and other parts. Because of the advantages of small size, less pollution, convenient operation, etc., and improved contact breaking capacity, reduced contact damage, and high reliability, it is widely used in power grid construction to control and protect high voltage during operation. role of equipment.

In this rapid economic development, while people are pursuing the improvement of the quality of life, the demand for electricity consumption is also increasing. In order to improve the quality of electricity and reduce unnecessary losses caused by power failure due to high load, high-voltage vacuum circuit breakers In the power grid, the circuit in normal operation can be cut off or connected; secondly, some accidents will inevitably be encountered in the operation of the power grid. After an accident occurs, it can cooperate with the line protection device to quickly cut off the accident point to ensure that all other The line can operate normally and is not affected by accidents, thereby reducing economic losses.

During the operation of the power grid, in order to avoid the aging of equipment and reduce the occurrence of accidents, it is necessary to maintain and repair each equipment regularly. The high-voltage vacuum circuit breaker is pollution-free during maintenance, easy to operate, low cost, long life, good operation effect, and ensure safety. Although the cost of operation is higher, it has more advantages than similar products in operation, such as many maintenance times and heavy workload.
