Brief description of the product:
A breaker which used vacuum as an arc extinction medium is called a vacuum circuit breaker. Vacuum circuit breaker has a high insulating medium for arc extinction as compared to the other circuit breaker.When an arc is opened by moving apart the contacts in a vacuum, an interruption occurs at the first current zero. With the arc interruption, their dielectric strength increases up to a rate of thousands time as compared to other breakers.
It is very simple in construction as compared to any other circuit breaker. Their construction is mainly divided into three parts, i.e., fixed contacts, moving contact and arc shield which is placed inside the arc interrupting chamber.
Current chopping in vacuum circuit breaker depends on the vapour pressure and the electron emission properties of the contact material. The chopping level is also influenced by the thermal conductivity–lower the thermal conductivity, lower is the chopping level.
Pay attention
Measures to prevent overvoltage. Vacuum circuit breaker has good breaking performance. Sometimes when breaking inductive load, high overvoltage is generated at both ends of inductance due to rapid change of loop current. Therefore, for dry-type transformers and other equipment with low impulse voltage resistance, it is best to install overvoltage protection devices, such as metal oxide arresters.
