Advantages of Vacuum Circuit Breakers

Advantages of Vacuum Circuit Breakers:

1. The arc is extinguished in a sealed container, and the arc and hot gas are not exposed. As an independent component, the arc extinguishing chamber is easy to install and debug.

2. The contact gap is very small, generally about 10mm, the closing power is small, the mechanism is simple, and the service life is long.

3. The arc extinguishing time is short, the arc voltage is low, the arc energy is small, the contact loss is small, and the breaking times are many.

4. The inertia of the moving guide rod is small, which is suitable for frequent operation.

5. The operating mechanism is small, the overall volume is small, and the weight is light.

6. The control power is small, and the operation noise is small when the switch is operated.

7. The arc extinguishing medium or insulating medium does not use oil, so there is no danger of fire and explosion.

8. The contact part has a completely sealed structure, which will not reduce its performance due to the influence of moisture, dust, harmful gases, etc., reliable work, and stable on-off performance.

9. After the vacuum circuit breaker is broken, the medium between the fractures recovers quickly, and the medium does not need to be replaced.

10. Within the service life of the vacuum switch tube, the contact part does not need to be repaired and inspected, generally up to 20 years without repair. The maintenance workload is small and the maintenance cost is low.

11. It has the function of multiple reclosing, which is suitable for the application requirements in the distribution network.
