Why do we use vacuum circuit breakers?

                                                                    Why do we use vacuum circuit breakers?

A Advantages

1. The dielectric recovery speed of the contact gap is fast after the arc is extinguished, and the performance of breaking near-zone faults is better.

2. Since the wear of the dredging is small when breaking the current, the electrical life of the contact is long, the full capacity breaking is up to 30-50 times, the rated current breaking is up to more than 5,000 times, and the noise is low, which is suitable for frequent operation.

3. Small size and light weight.

4. Suitable for breaking capacitive load current.

5. Energy saving and environmental protection: Vacuum circuit breakers do not consume energy when disconnecting the circuit, and do not produce harmful substances, which can ensure the clean and environmentally friendly operation of the power system.

B Application scenarios

Medium voltage distribution system: Applicable to 3-40.5kV three-phase AC system, it is an ideal choice for industrial and mining enterprises, power plants and other places; 

High voltage field: It can withstand 10-126kV voltage to meet the needs of grid stability and frequent operation;

Special environment: Such as railway traction current switching, industrial equipment protection, etc., with high reliability and impact resistance.

C Technological development

Modern vacuum circuit breakers have further improved their breaking capacity through optimized design (such as high vacuum maintenance technology and rapid vacuum recovery mechanism).

In summary, vacuum circuit breakers have become an indispensable key equipment in the power system due to their arc extinguishing performance, long life and low maintenance cost.
