Frequently Asked Question
Do you have any question?
Vacuum circuit breakers offer several advantages. Firstly, they can interrupt high fault currents without generating harmful gases or byproducts, making them environmentally friendly. Secondly, they have a longer lifespan and require less maintenance compared to other circuit breaker types. Lastly, their compact design and suitability for indoor installation make them an ideal choice for various applications.
When a fault occurs, the control mechanism activates the VCB, causing the contacts to separate. This action creates an arc between the contacts, which is then directed into the arc extinguishing chamber. The vacuum inside the chamber helps to prevent the arc from re-striking, and various techniques, such as cooling and deionization, are employed to extinguish the arc efficiently.
Indoor high voltage vacuum circuit breakers find extensive use in power generation, transmission, and distribution systems. They are also employed in industrial facilities, commercial buildings, and other areas where reliable protection against electrical faults is required. Their ability to handle high voltages and currents, combined with their safe and environmentally friendly operation, makes them a preferred choice for critical electrical infrastructure.
