Quick Details
Specifications
GVM6-12 Series Permanent Magnet Embedded Poles Type Indoor Vacuum Circuit Breaker
GVM6-12 series permanent magnet embedded poles type indoor vacuum circuit breaker is a three-phase AC 50Hz, rated voltage of 12kV indoor switchgear. I loaded the company with its own research and development of permanent magnetic actuator for industrial and mining enterprises, power generation and substation facilities as electrical control and protection purpose. The product has high reliability and long life characteristics, especially suitable for frequent operation, repeatedly breaking conditions, such as short-circuit current of the place.
Note: this models vacuum interrupter chamber seal replaced with ordinary insulation tube column installation method, the model GVM6-12P.
Main Features
1.High reliability, long life, maintenance-free.
2. China's first permanent magnetic actuator mechanical life of up 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 lighting, 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 Celsius, not less than -25 Celsius.
2. Altitude: not exceed 1000m, plateau type not exceed 3000m.
3. Relative Humidity: daily average is not more than 95%, month average is not more than 90%, statured vapor pressure daily average is not more than 2.2x10-3 MPa, month average is not more that 1.8x10-3 MPa. The temperature dropped rapidly during the period of high humidity is that it may gel.
4. Earthquake Intensity: not more than 8.
5. No fire, explosion hazard, serious filthy, chemical corrosion, as well as places of intense vibration.
