China LW16 High Voltage SF6 Circuit Breaker Manufacturers, Suppliers, Factory

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:

At Timetric Electric, we know how important the vacuum interrupter of the VS1 vacuum circuit breaker is to the performance of the equipment. Let’s discuss how to determine whether there is a leakage problem in the VS1 vacuum circuit breaker and how to solve it.

In Timetric Electric’s VS1 vacuum circuit breaker, loop resistance is a key parameter used to evaluate the connection quality of the conductive loop. The value of the loop resistance is affected by many factors, mainly depending on the contact resistance between the dynamic and static contacts, which includes shrinkage resistance and surface resistance.

VS1-12 vacuum circuit breaker alias: ZN63A vacuum circuit breaker is independently developed by Zhejiang Xuli Electric Co., Ltd. It is based on the full digestion and absorption of traditional VS1 vacuum circuit breaker technology in the early stage, and is combined with domestic electric locomotive vacuum circuit breakers. The matching design has been improved for specific operating conditions and technological innovation has been achieved. This circuit breaker has the following advantages:

With the development of social economy, our requirements for electricity are getting higher and higher. However, the requirements for high-voltage breaking short-circuit current are also getting higher and higher. So what is the rated breaking short-circuit current pressure? This pressure is actually what we refer to. What is the working pressure corresponding to the rated breaking short-circuit current corresponding to the working pressure of the contacts in the vacuum arc extinguishing chamber of the vacuum circuit breaker? (This pressure is related to our insulating tie rods)

We want to know what the overvoltage suppression cabinet looks like, so let's first understand what is overvoltage?
