What is the rated stable current of the VS1 vacuum circuit breaker? We often see such a parameter on the nameplate of the vacuum circuit breaker, or this parameter is seen on the manual. So what is the rated stable current? What is its value?

The influence of various mechanical characteristics on product performance The quality of the product's mechanical characteristics has an important relationship with the various electrical properties of the product, and affects the reliability of the product's operation. To measure the performance of the vacuum circuit breaker, the performance of the vacuum isolation chamber itself is important, but the mechanical characteristics also play a decisive role. The relationship between each mechanical characteristic parameter and product performance is described as follows:

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.

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.

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:

Speaking of this problem, let’s first understand what overvoltage is: Overvoltage refers to the 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?
