Vacuum interrupter has many advantages over other types of circuit breakers, and here are some of the main ones:

1. High-speed circuit break: Vacuum interrupter is able to achieve current interruption in a very short time, with fast circuit breaking capability, helping to protect the power system from overload and short circuit.
2. High reliability: Since there is no gas or other impurities in the vacuum, the Vacuum interrupter works stably and reliably, and is not affected by the external environment, with long-term stable performance.
3. Low maintenance requirements: Compared to other types of circuit breakers, the Vacuum interrupter has lower maintenance requirements and requires little to no regular maintenance, which can reduce operating costs.
4. Low wear of components: Since there are no gases and contact substances in the vacuum, the internal parts of the Vacuum interrupter have less wear and a longer service life.
5. Environmental protection: Vacuum interrupter does not use harmful gases such as SF6, will not cause pollution to the environment, and meets environmental protection requirements.
6. In general, vacuum interrupter is widely used in power systems due to its advantages of high-speed circuit breaking, high reliability, low maintenance requirements, low wear of components and environmental protection.
