China OEM 11kv Vacuum Circuit Breaker 3150a - VSM-12 Series Permanent Magnetic Operating Mechanism – Ghorit

 Main Features

1. High reliability, long life, maintenance-free.
2. China’s first permanent magnetic actuator mechanical life of up to 100,000 times.
3. With the traditional actuator compared without mechanical removal, locking devices, parts and components significantly reduced the number of hours worked with only one moving parts, low failure rate.
4. Actuator performance and interrupter breaking. Closing the features needed for a very consistent.
5. All sub-reliable operation of the bistable gate.
6.With anti-skip function.
7.With controlling power low-voltage alarm refuse to close.
8. Mechanical manual sub-sub-gate and electric gate at the same rate, in the secondary power supply fault conditions, the application of an emergency sub-gate.
9. AC and DC energy storage operation type, operating current is less than 2A, can be done o-co-o operation within 2 hours after the blackout .
10. Highly reliable operation of control circuit module that can be tolerated in the run-time lightning, surge and other harsh conditions.
11. Versatility, installation size and ZN63 VS1 compatible with other products.

The use of environmental conditions

1.Ambient temperature: not higher than +40℃ , not less than -15℃ (at -30 ℃ to allow storage and transportation).
2. Altitude: not exceed 1000m.
3. Relative humidity: daily average of not more than 90%,saturated vapor pressure on the average of not more than 2.2 × 10 -3 MPa, On average not more than 1.8 × 10 -3 MPa. Thetemperature dropped rapidly during the period of high humidity is that it may Gel.
4. Earthquake intensity: not more than eight.
5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
