The Vacuum circuit breaker can intrupt large capacitor current or charging current without restrike and rate of restriking voltage is negligible, so vacuum circuit breaker used for capacitor bank switching or transformer switching. 5. When voltage is high and current to be interrupted is small this breaker are very useful than other breakers.
Over the last decades Vacuum Circuit Breakers (VCBs) are the most preferred switching devices in the medium voltage levels up to 52 kV. More than 80% of today’s new installation employs vacuum switching technology .
Advantages of Vacuum Circuit Breakers The vacuum inside the breaker has high dielectric strength, making VCBs highly effective at interrupting high voltage currents. This characteristic allows for compact designs as the distance required between contacts to quench the arc is significantly reduced compared to air circuit breakers.
Vacuum Circuit Breakers have earned their place as leading contenders in electrical protection due to their high interrupting capacity, compact design, and low maintenance requirements. However, they also present disadvantages, including higher initial cost, limitations in current ratings, and potential vacuum arc issues.
The vacuum circuit breaker or Vacuum interrupter has the following main parts: 1. Moving Contacts 2. Fixed contacts 3. arc Shields 4. Stainless steel bellows and bellows shield 5. Insulating envelop
VCBs are renowned for their durability and long operational life. The vacuum environment minimizes the erosion of the contacts due to arcing, ensuring that the circuit breaker can operate for many thousands of cycles without significant maintenance. One of the most significant advantages of VCBs is their low maintenance requirements.
