Indoor High Voltage Vacuum Circuit Breaker puts you in control of safety
The indoor high voltage vacuum circuit breaker is a kind of switching equipment utilizing vacuum insulation and spring mechanism, which is mainly used for cutting off and connecting high-voltage circuits.
When the operating mechanism applies the closing force to the circuit breaker, the movable contact comes into contact with the static contact to form an on-state. The air between the movable and static contacts is quickly drawn out, forming a high vacuum-insulating gap. Since the vacuum has very high insulating properties, it can effectively isolate high voltage.
When a circuit fault occurs or the power supply needs to be cut off, the operating mechanism applies a braking force to the circuit breaker. The spring mechanism comes into play, causing the movable contact to quickly disengage from the static contact, thus realizing the circuit cut-off. Because the air between the movable and static contacts has high insulating properties, it can effectively prevent the generation and propagation of electric arcs even when cutting off high-voltage circuits.
Indoor high-voltage vacuum circuit breaker has the ability to quickly cut off the fault current, can cut off the fault current up to thousands of amperes in a very short period of time, and effectively protect the power equipment and personnel safety.
Due to the use of vacuum as an insulating medium, the indoor high voltage vacuum circuit breaker has extremely high insulation performance, which can effectively prevent the generation and propagation of electric arc and ensure the safe operation of the power system.
The vacuum insulation and spring mechanism design of indoor high-voltage vacuum circuit breakers make them have a long service life, generally up to hundreds of thousands of operations.
The indoor high-voltage vacuum circuit breaker has a compact structure and is easy to maintain, which facilitates regular inspection and maintenance.
