Operating Mechanism for Circuit Breaker
According to long-term statistical analysis of operation by electric power department ,among various reasons for faults to high-medium-voltage switchgers in terms of different regions,different switch types and voltage levels, the proportion of faults incurred by operating mechanism is up to 30%-70%:therefore,raliablity of operating mechanism has become an important indicator for evalution of technical level of SF6 AC metal-enclosed switchgear.
MGC switchgear adopts time-proven operating mechanism with stable and reliable performance,comprising mechanical and electric moduels:the electric module is composed of conductor and circuit board as preliminarily connected ,which can facilitate electric upgrading of manual operating mechanism,replacement,repair and mainteance of circuit board;it has the following features:
1.Splint structure of high stability and reliability as well as long service life.
2.Compact structure and high output transmission effciency.
3.Small volume and perfect fitting with miniaturization of SF6 gas insulated AC metal-enclosed switchgear.
4.High corrosion resistance:All parts of operating mechanism have received 96h salt spray test to ensure reliable operation under abominable conditions.
5.Manual mechanism is easy to upgrade,which can satisfy demands of different users.
6.Motorized operating mechanism control madule is with integrate modularized design,which is reserved with secondary socket to facilitate secondary wiring of mechanism and is mouted frontally for easy maintenance.
7.Optimal rigid interlocking device is safe and reliable,which can prevent maloperation to the maximum.
