VS1-24KV indoor vacuum circuit breaker

VS1 indoor medium voltage Vacuum Circuit Breaker is a three-phase AC 50Hz ,rated voltage 6KV,12KV,24KV switch equipment of power system. Breaker adopts the integral design of the actuating mechanism and the breaker body, which can be used as a fixed installation unit or as an individual VCB carriage together with handcart. They have a long life expectancy. There is no adverse effect on the vacuum, even from frequent switching of operating and short-circuit currents. Our products are widely used in: 1 – Transformers and distribution substations 2 – Generator control and protection 3 – Capacitor bank control and protection, etc

Features

1. The arc is extinguished in a sealed container, and the arc and hot gas are not exposed. As a separate component, the arc extinguishing chamber is simple and convenient to install and debug.​​
2. The contact gap is very small, generally about 10mm, the closing power is small, the mechanism is simple, and the service life is long.​​
3. The arc extinguishing time is short, the arc voltage is low, the arc energy is small, the contact loss is small, and the breaking times are many.​​
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 need oil, there is no danger of life 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. to reduce its performance. Reliable work, 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 medium will not age and do not need to be replaced. During the service life, the contact part does not need to be repaired or inspected. Generally, it 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 oil-less circuit breaker.​​
11. It has the function of multiple reclosing, which is suitable for the application requirements of the distribution network.
