This series of circuit breakers take Y type as the basic product,composed of four parts: insulating ensulating enclosure,operating mechanism,contact system and release.The operating mechanism of circuit breaker enables the contact to fast open and close.The positions of "close","Open", "Re tripping" and "Free tripping"are identified with the handle position.
C type,J type and G type circuit breaker are connected with a requlsion current-limiting contact system made up of a parallelconductor in series at the back of bottom plate of Y type circuit breaker, compared with J type circuit breaker, this system repulsion contact is longer and the breaking distance is larger, therefore, the current is limited more smooth; however, under normal opening and closing, and the release operates within the short circuit setting protecting value, Y type circuit breaker finishes the current limiting independently. Once the network occurs large current or ultra large short circuit current, the series-connected repulsion current-limiting contact is repulsed fast by electric power, and brings arc to limit current. In the process of contact repulsing, the release operation and operation mechanism make Y type contact break. And the repulsion current-limiting contact comes back to original state for current fall or disappearance. C type circuit breaker is used for distribution protection in the transformer power net of 630kVA and below, can get the best economical efficiency through selecting economical material, simplifying structure and improving technology, etc..
