What is Vacuum Circuit Breaker and it’s Advantages?

Vacuum circuit breakers are generally utilized in situations that need medium voltage circuit breakers. Some of the most well-known models being 11kV and 33kV Vacuum Circuit Breaker. Arc extinguishing in a Vacuum Circuit Breaker uses a moderately new method of handling short circuits, overloads and ground faults. Vacuum circuit breakers additionally have the highest protecting strength of all circuit breaker types.

While vacuum circuit breakers may not be the most ordinary circuit breakers on the market, they are some of the most dependable. Medium voltage vacuum circuit breakers are used across an amazing assortment of commercial & industrial applications, as well as hotels and healthcare facilities to water management plants & educational facilities.

PASCAL is the top 33kV Outdoor Vacuum Circuit Breaker Manufactures in India because of the unmatchable rapidity, trustworthiness and easiness of maintenance of its VCB panels.

Advantages of Vacuum Circuit Breakers:

While the advent of Vacuum Circuit Breakers in the early 1960s, the technological parameters of vacuum circuit breakers have been constantly enhanced, with great performance. The advantages developed quickly, and the application in high-voltage switch cabinets has become increasingly broad.

Vacuum Circuit Breakers Points -

1. Extinguish the arc in a sealed container, & the arc and hot gas are not uncovered. As a separate component, the arc extinguishing chamber is simple and suitable to install and debug.

2. The contact gap is very little, generally about 10mm, the closing power is little, the instrument is straightforward, and the service life is long.

3. The arc quenching time is short, the arc voltage is low, the arc energy is small, the contact loss is small, and the quantity of breaking time is huge.

4. The inactivity of the movable guide rod is small and can be used habitually.

5. Small operating mechanism, small size & light weight.

6. The control power is small, & the action noise is little during switch operation.

7. The arc extinguishing medium or protecting medium does not use oil, there is no danger of living and explosion, and it is secure.

8. The contact head is divided into a totally sealed structure, and its performance will not be reduced by the influence of moisture, dust, harmful gases, etc. dependable work, and stable on off performance.

9. After the arc is broken, the medium between the features recovers rapidly, and the medium does not need to be replaced.

10. The ring will not age or should to be replaced. Within the services life, the contact part does not need to be repaired or inspected. Normally, it can be up to about 20 years without inspection. The maintenance workload is little, and the maintenance price is low, simply about 1/20 of the oil-less circuit breaker.

11. With numerous reclosing function, suitable for the application requirements of distribution network.
