China sf6 vacuum circuit breaker Manufacturers, Suppliers, Factory

As the name implies, a vacuum circuit breaker is a circuit breaker that uses vacuum to complete arc extinguishing. The vacuum chamber, also known as the vacuum interrupter, is responsible for opening and closing the current-carrying contacts.

Speaking of this problem, let’s first understand what overvoltage is: Overvoltage refers to a long-term voltage fluctuation phenomenon in which the root mean square value of the AC voltage under power frequency increases, exceeds 10% of the rated value, and lasts for more than 1 minute; The appearance of voltage is usually the result of a moment of load switching. Occurs when inductive or capacitive loads are connected or disconnected during normal use. What are its occurrences?

The energy storage motor in the vs1 vacuum circuit breaker is an important component of the vacuum circuit breaker. When we use the VS1 vacuum circuit breaker, we sometimes encounter the energy storage motor being burned. So what are the main reasons for it being burned?
