Types of Vacuum Circuit Breaker

VCB Vacuum Circuit Breaker Construction

The structures vary among different types of vacuum circuit breakers. In general, a vacuum type circuit breaker basically consists of a vacuum interrupter bottle, operating mechanism, insulation system, terminal connections, and auxiliary devices. These vacuum circuit breaker components work together to ensure reliable and safe operation of the VCB, making it a crucial component in modern power distribution systems. Liyond not only offers complete vacuum circuit breaker solutions, but also vacuum circuit breaker accessories.

Vacuum Circuit Breaker Working Principle

An electrical vacuum breaker works on the principle of arc quenching in a vacuum environment. When the power circuit breaker is working, an electric arc will be formed between the contacts due to the ionization of metal vapor. The arc is inside a sealed vacuum chamber where the vacuum environment has a high dielectric strength to withstand high voltages without breaking down. This efficient arc quenching mechanism enables vacuum type circuit breaker to reliably interrupt high currents, making them a popular choice for medium and high-voltage power distribution systems.

Vacuum Circuit Breaker FAQs

The MV vacuum circuit breaker usually should be checked once or twice a year, but it depends on how they're used and where they are. Check the instructions and industry guides. Look for damage, loose parts, and make sure the VCBs work smoothly.
A few things: The vacuum inside the electrical vacuum breaker can weaken (rare), parts can wear out, and the controls might have problems. Bad environments can also cause issues.
Several checks: Look it over, make sure the VCB breaker opens and closes quickly, check the connections, test the insulation, and check the vacuum. Experts with special tools usually do this.
