Cause analysis: In the normal operating state of the circuit breaker, the circuit breaker does not open when there is no external operating power supply and mechanical opening action. After confirming that there is no misoperation, check the secondary circuit and the operating mechanism. It was found that the auxiliary switch contacts in the operating mechanism box were short-circuited, and the opening power supply was connected to the opening coil through the short-circuit point, resulting in false opening.

In the previous article, we talked about how long is the life of the VS1 vacuum circuit breaker? This article is also what we, as electricians or electricity users, are most concerned about? Why is it said to be the best concern for our electricity users? First, to reduce the number of power outages, second to reduce economic losses caused by vacuum circuit breaker failures, and third to reduce power accidents. Various explanations can reflect the benefits that the extended life of VS1 vacuum circuit breaker brings to us. So how can we make our VS1 vacuum circuit breaker last longer? Let’s take a look below.

High-voltage trolleys are usually used in high-voltage central cabinets, providing great convenience and safety for daily maintenance, inspection and replacement. Although the isolation trolley and the fuse trolley are very similar in appearance and function, there are some differences between them.

The manually operated Timetric Electric ZW32 vacuum circuit breaker protects power lines through its mechanism, vacuum interrupter and transformer. Let's take a closer look at their working principles and protective functions:
