Since 1984, our enterprise has been engrossed in providing a high grade gamut of Vacuum Circuit Breakers. Appreciated to be installed at commercial, industrial and residential places, these products are widely used to protect an electrical circuit from over current or overload. These products are manufactured using premium grade components with the aid of modern techniques under expertsï¿½ direction at our well-equipped production unit. These Vacuum Circuit Breakers can be availed from us in several specifications at pocket-friendly prices.
A point which many industrialists are unaware of, is that vaccum provides extremely high insulating strength, and has remarkable arc quenching characteristics which are even better than other mediums. This is the main reason why in majority of the circuit breakers, vaccum is used as an arc quenching source. The level of such a medium generally lies between 10^-7 to 10^-5 torr.
Although the technology created is appropriate for mostly average voltage applications, we would inform you that the advanced tech developed for handling higher electric flux vaccum is not commercially viable.
Principle of Vacuum Circuit Breaker
The following is an explanation of the arc present in the vaccum circuit breaker, along with it’s extinction-
When the link of the breaker is opened in the vaccum medium at (10^-7 to 10^-5 torr), an arc is created between the contacts, with the help of the ionisation process of metal vapours of contacts. But, the curve is destroyed as soon as possible, simply because the electrons and ions developed by the metallic vapours cools down rapidly on the surface of the container, which thus provides a fast retrieval of electric strength.
Construction of Vacuum Circuit Breaker
The construction of the simple above mentioned mechanism is as follows-
