Simple Vacuum Circuit Breaker Diagram. The vacuum circuit breaker has mainly two phenomenal properties. The following paragraphs describe the control circuit components.
The operation of opening and closing of current carrying contacts and associated arc interruption take place in a vacuum chamber in the. In this vedio i will explain about the metal enclosed vacuum circuit breakers 11kvcircuit breaker 11kv vcb panel sld types of vacuum interrupter contac. The pressure inside the vacuum interrupter is approximately 10 4 torrent and at this pressure very few molecules are present in the interrupter.
The technology is suitable for mainly medium voltage application.
As far as construction is concerned vacuum circuit breaker is very simple in comparison to an air or oil circuit breaker. From the figure shown above the vacuum circuit breaker consists of fixed contact a moving contact and a vacuum interrupter. The moving contact is connected to the control mechanism by stainless steel bellow. They are designed and manufactured to operate within the ansi c37 standards for indoor oiless circuit breakers.
