Abstract

The invention relates to a movement mechanism of a separation plate in a drawer seat of a drawer type circuit breaker. The mechanism comprises an upper connecting rod, a lower connecting rod, a sliding shaft, a guide rail and a movement side plate, wherein the lower connecting rod is rotatably connected with a side plate of the drawer seat; the upper end of the upper connecting rod is connected with the separation plate and the lower end of the upper connecting rod is hinged to the lower connecting rod; the sliding shaft is arranged on the upper connecting rod and the guide rail is arranged on the side plate of the drawer seat; the guide rail is used as a movement limiting rail of the sliding shaft, so that when the upper connecting rod moves, the vertex at the upper end of the upper connecting rod moves up and down; the movement side plate is parallel to the side plate of the drawer seat; in a horizontal sliding process of the movement side plate, the lower connecting rod is pushed to rotate, so that the upper connecting rod is driven to move; the movement of the upper connecting rod drives the separation plate to move up and down. Compared with the prior art, the upper connecting rod and the lower connecting rod are hinged, a clamping condition does not occur and the stability is high; compared with other mechanisms, door opening movement is more rapid. The movement angle of the connecting rods is limited by the shapes of the connecting rods, so that the mechanism does not pass through a dead point, and the reliability performance of movement is ensured.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, and in particular relates to a moving mechanism of an isolation plate in a drawer seat of a drawer-type circuit breaker. Background technique [0002] Universal circuit breaker, also known as frame circuit breaker, can connect, carry and break current under normal circuit conditions, and can also break fault current under specified abnormal circuit conditions. As far as the application of universal circuit breaker is concerned, it is divided into fixed circuit breaker and drawer circuit breaker. Because the drawer circuit breaker is installed in the drawer and can be moved in the drawer, it has the advantages of convenient detection and maintenance, so it is widely used. use. [0003] The drawer type circuit breaker is composed of two parts: the circuit breaker body and the drawer type socket. During use, the electrical circuit can be disconnected by the main contact of the circuit...
