The advantages of vacuum circuit breakers

The advantages of vacuum circuit breakers are as follows

1. Instead of arc in the seal container, arcs and hot gas are not exposed. As an independent element, the arc extinguishing room is simple and convenient to install and debug.
2. The gap between the contact is very small, generally about 10mm, the gates are small, the institution is simple, and the service life is long.
3. Short arc off, low arc voltage, small arc energy, small contact loss, and more disconnection!
4. The inertia of the dynamic rod can be used frequently.
5. The operating agency is small, the whole machine is small, and the weight is light.
6. Small control of power, small movement noise during switching.
7. The arc extinguishing medium or insulating medium does not need oil, there is no risk of fire and explosion, safety.
8. The contact part is a completely sealing structure, which will not be affected by the influence of moisture, dust, and harmful gases to reduce its performance. The reliable work of work is stable.

9. After the vacuum is broken, the medium is recovered quickly after the breaks are broken, and the medium does not need to be replaced.

10. During the use of the vacuum arc destroy, the contact part does not need to be maintained. It is checked, and it can generally not be maintained for about 20 years. The maintenance workload and the low maintenance cost are only about 1/20 of the less oil breaking.

11. It has multiple re -closure functions, suitable for application requirements in the distribution network.
