Spring Operating Mechanism for Gas Insulated Switchgear

spring operating mechanism is dedicated for rotary switch-fuse combination of gas insultated switchgear rated up to 24KV.Configured with fuse tripping interlock and tension spring,it can perfectly compatible with F-module.Motorized mechanism is also avaliable.
It has rigid interlocking device with the lower-door to prevent unexpected access to the cable comparatment when the main circuit is still live.
Motorized operation control module is placed at the front ,easy for repair and mainteance .It is also reserved with secondary socket to facilitate secondary wiring of mechanism.

Basic requirements for operating mechanisms

The performance and quality of the operating mechanism directly affect the performance and reliability of the circuit breaker. The basic requirements for operating mechanisms for high voltage circuit breakers are: 

1, the action is firm, stable, and the brakes are agile

2, satisfactory operating energy, satisfactory circuit breaker breaking, closing

3, adhere to the interpretation

4, anti-"beating" function

5, interlocking function

6, buffer function

7, free to trip

8, open

9, reset
