AI Customer ServiceMany; some vacuum circuit breakers have extremely serious defects, which can easily cause accidents to leapfrog and cause large-scale power outages. Let's walk into the site where electrical engineers deal with vacuum circuit breaker failures together, so that we can accumulate experience and do comprehensive maintenance. 1.
In the case that the energy storage is not in place, if the line has an accident and the circuit breaker refuses to open, it will cause the accident to leapfrog and expand the scope of the accident; if the energy storage motor is damaged, the vacuum switch cannot be opened and closed.
As vacuum circuit breakers are widely used in the power industry, due to different manufacturers, some vacuum circuit breakers have better performance, less overhaul and maintenance workloads, and high power supply reliability; some vacuum circuit breakers have poor performance and compare problems.
The vacuum circuit breaker fails to open According to the different causes of the failure, the following failure phenomena exist: In the event of an accident, the relay protection operates, but the circuit breaker cannot be separated. The resistance of the opening coil increases and the opening force decreases;
Choose a vacuum circuit breaker integrated with the main body and the operating mechanism; Operators should pay attention to whether there is a discharge phenomenon outside the vacuum bubble of the circuit breaker during the inspection.
As long as it is within the normal operating conditions and the technical parameters of the circuit breaker, the VD4 vacuum switch can meet the needs of the power grid under normal or accident conditions. operations, including closing, opening and breaking short-circuit currents.
