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:

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 the opening distance of the VS1 vacuum circuit breaker, which is one of the important indicators of mechanical characteristics. In this article, we talked about the overtravel of the VS1 vacuum circuit breaker, which is also one of the important indicators of the mechanical characteristics. So what is the overtravel of VS1 vacuum breaker? What does it do? What is its range value?

First, let's talk about SF6 circuit breakers. We know that the biggest difference between SF6 circuit breakers and vacuum circuit breakers is the difference in arc extinguishing media, so it is necessary to explain the properties of SF6 gas first.

In modern electronic devices, load switches play a vital role as an important power management component. This article will explore the definition, working principle, application areas and importance of load switches in power management.

To understand the difference between VS1 plateau vacuum circuit breakers and ordinary VS1 circuit breakers, and what kind of VS1 circuit breakers are called plateau circuit breakers, we first need to understand what altitude is and what altitude is considered a plateau.
