Embodiment 1

[0018] refer to figure 1 , figure 2 and image 3 , this embodiment provides a circuit breaker control mechanism for use in a switch cabinet, the switch cabinet includes two circuit breakers 2 arranged side by side on the laminate 1, and each circuit breaker 2 is correspondingly provided with a rear side A circuit breaker joint 3, each circuit breaker 2 is also provided with a screw rod 4 for driving the circuit breaker 2 to move back and forth.

[0019] The cross-section of the screw rod 4 is an elliptical structure, and a lift-type drive slider 5 is also arranged between the rear side of one circuit breaker 2 and the breaker joint 3, and the lift-type drive slider 5 faces one side of the circuit breaker 2. The side is a descending wedge-shaped structure, and when the lifting drive slider 5 and its corresponding circuit breaker 2 are in a non-contact state, the upper end of the descending wedge-shaped structure in the lifting drive slider 5 is located higher than the lower ...

Embodiment 2

[0021] refer to Figure 4 , Figure 5 and Figure 6 , this embodiment provides a circuit breaker control mechanism for use in a switch cabinet, the switch cabinet includes two circuit breakers 2 arranged side by side on the laminate 1, and each circuit breaker 2 is correspondingly provided with a rear side A circuit breaker joint 3, each circuit breaker 2 is also provided with a screw rod 4 for driving the circuit breaker 2 to move back and forth.

Abstract

The invention provides a breaker control mechanism used in a switch cabinet. The cross section of a lead screw is of a non-circular structure, a lifting type driving sliding block is arranged between the rear side of one of breakers and a breaker joint, one side of the lifting type driving sliding block, which is towards the breaker, is a falling wedge structure, a lifting type lead screw limiting block is correspondingly arranged right under a lead screw in the other breaker, through holes for the lifting type driving sliding block and the lifting type lead screw limiting block to pass through are correspondingly arranged on a layer plate, the lower ends of the lifting type driving sliding block and the lifting type lead screw limiting block are correspondingly fixed to two ends of levers through connecting rods which penetrate into the through hoes, and the lower end of the lifting type lead screw limiting block is also correspondingly provided with a reset spring. The problems are solved that an existing breaker control mechanism has a high requirement for machining precision, is inflexible to use, and is easy to clamp and not easy to reset, and once misoperation occurs, a situation that a breaker and a back-up breaker are in a working state at the same time is easy to occur. 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...
