Abstract

The invention provides a circuit breaker control mechanism used in a switch cabinet. The cross-section of the screw rod is a non-circular structure. There is also a lift-type drive slider between the rear side of one circuit breaker and the joint of the circuit breaker. The lift-type The side of the driving slider facing the circuit breaker is a descending wedge-shaped structure, and the other circuit breaker is provided with a lifting screw limit block directly below the screw rod, and a lifting driving slider and a lifting The through hole through which the type screw limit block passes, the lower ends of the lift type drive slider and the lift type screw limit block are respectively fixed on the two ends of the lever through the connecting rods passing through the through hole, and the lift type screw limit block The lower end of the block is also provided with a return spring correspondingly. In order to solve the problems that the existing circuit breaker control mechanism requires high machining accuracy, is not flexible to use, is prone to jamming, and is not easy to reset. The invention belongs to the field of switch cabinets.

Description

technical field [0001] The invention relates to a mechanism for controlling a circuit breaker, which belongs to the field of switch cabinets. Background technique [0002] At present, according to the relevant power distribution design specifications, when there are important loads in the load, it is necessary to configure a dual power supply distribution scheme, which requires the configuration of the main circuit breaker and the backup circuit breaker in the electric Only one circuit breaker can be in the working position at the same time. The existing circuit breaker control mechanism generally uses a manual screw mechanism to control the entry and exit of the circuit breaker. It is not easy to reset. At the same time, the circuit breaker and the backup circuit breaker are controlled separately. Once misoperation, it is easy to happen that the main circuit breaker and the backup circuit breaker are in working state at the same time, and it is easy to cause equipment failu...
