Vacuum Circuit Breaker is a kind of circuit breaker with vacuum as the arc extinguishing and insulating medium, which has the following main advantages:
1. the core performance advantages Products Description
- Fast arc extinguishing ability
No gas free in the vacuum environment, the arc can be quickly extinguished to avoid damage to the equipment by arc extension. Small contact opening distance (e.g. 10mm) and short stroke of operating mechanism further enhance the arc extinguishing efficiency.
- High fracture capacity
Can withstand high voltage and high current, continuous breaking times of more than 10,000 times, in the rated short-circuit current can be repeated tens of times or even hundreds of times, applicable to 10-35kV and other high-voltage power systems.
Low contact loss
Low arc voltage, small arc energy, small contact wear, long service life, and significant extension of mechanical life.
2. the structure and maintenance advantages
- Small size and light weight
The vacuum interrupter has an overall compact structure, it is easy to install and transport, and is particularly suitable for substations and distribution networks with limited space.
- Less or no maintenance
No arc extinguishing medium chemical reaction and mechanical wear, low maintenance costs, high operational reliability.
- Good sealing
Arc extinguishing chamber sealing, internal media (vacuum or SF₆) will not be exposed, high security.
3. the environment and safety advantages
- Environmentally friendly and non-polluting
The opening process does not produce harmful gases (such as SF₆ decomposition products), in line with environmental requirements.
- High safety factor
No risk of explosion, excellent insulation performance, suitable for high voltage scenarios.
4.Other advantages
- Easy to operate ：Small control power, low action noise.
- Strong adaptability: can be frequently operated to meet the needs of industrial and mining enterprises, power plants and other scenarios.
In summary
vacuum circuit breaker with its excellent arc extinguishing performance, mechanical life and environmental characteristics, become the mainstream protection equipment in the power system.
