China LW36 40 5KV Sulfur Hexafluoride Circuit Breaker Manufacturers, Suppliers, Factory

In the previous article, we talked about the mechanical atresia (lock) of the VS1 vacuum section device. What is the role of the fixed spindle of the device? ——It is a mechanical atresia between fixed and high -voltage forms. Why must you choose a mechanical atresia?

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?

Vacuum circuit breakers use vacuum as arc extinguishing and insulating medium. They have strong arc extinguishing ability, small size, light weight, long service life, no fire and explosion hazards, and do not pollute the environment. Therefore, they are widely used in the medium voltage field.

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:

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.

Epoxy resin solid insulation, no oil, no SF6, no harm to the environment vacuum breaking, longitudinal magnetic field arc extinguishing, stable and reliable.
