Advantages of vacuum circuit breakers:
1. Extinguish the arc in a sealed container, and the arc and red-hot gas are not exposed. As a separate element, the interrupter is simple and convenient to install and debug.
2. The contact gap is very small, generally about 10mm, the closing function is small, the mechanism is simple, and the service life is long.
3. The arc extinguishing time is short, the arc pressure is low, the arc energy is small, the contact loss is small, and the number of interruptions is large.
4. The inertia of the moving guide rod is small and can be used frequently.
5. The operating mechanism is small, the whole machine is small in size and light in weight.
6. The control power is small, and the action noise is small when the switch is operated.
7. The arc extinguishing medium or insulating medium does not use oil, there is no danger of living and explosion, and it is safe.
8. The contact head is divided into a completely sealed structure, which will not be affected by moisture, dust, harmful gases, etc., and its performance will be reduced. Reliable work and stable on-off performance.
9. After the arc is broken, the medium between the fractures recovers quickly, and the medium does not need to be replaced.
10. The ring does not age and does not need to be replaced. During the service life, the contact part does not need to be repaired and inspected, and generally can be up to about 20 years without maintenance. The maintenance workload is small and the maintenance cost is low, which is only about 1/20 of the less oil circuit breaker.
11. It has the function of multiple reclosing, which is suitable for the application requirements of the distribution network.
The company has been customer-centric, the concept of creating value for customers, winning the market with quality and service, and sincerely hopes to cooperate with all sectors of society to create success, create brilliance together, and work together to create a better tomorrow!
In line with the concept of credibility and service-oriented, the company warmly welcomes new and old customers to inquire, visit and negotiate business!
