Abstract

The invention provides a double-breakpoint moving contact apparatus. The apparatus comprises a moving contact limiting component, a first moving contact shaft, a first moving contact spring, a second moving contact spring, a first limiting component shaft, a second limiting component shaft and a moving-contact contact blade. The moving contact limiting component and a moving contact shell form a moving contact installation space. The first limiting component shaft is arranged on an upper end surface of an inner side of the moving contact limiting component. The second limiting component shaft is arranged on a lower end surface of the inner side of the moving contact limiting component. The first moving contact spring sleeves the first limiting component shaft. One end of the first moving contact spring is connected to the upper end surface of the inner side of the moving contact limiting component and the other end is connected to an upper side surface of the moving-contact contact blade. In the invention, a rotary-type double-breakpoint structure is adopted; the moving-contact contact blade adopts a multiple-piece type and a model with main and auxiliary contacts. Through using the double-breakpoint structure, a short-circuit connection and disconnection capability of a product can be effectively increased. Through using a multiple-piece type contact structure, a short time connection and short-term tolerance capability can be increased. And damages of an arc to a main contact can be reduced.

Description

technical field [0001] The invention relates to a changeover switch, in particular to a double break point moving contact device. Background technique [0002] The existing automatic conversion has the following mainstream combination methods: motor operating mechanism plus two circuit breaker body contact systems, motor operating mechanism plus two isolating switch contact systems, motor operating mechanism plus integrated body contact system, electromagnetic operation Mechanism plus integrated body contact system; in addition, there is an older mechanical interlock plus two contactor type transfer switch, which has gradually been eliminated. [0003] The above transfer switches have their own defects. Specifically, the motor operating mechanism has a long conversion time due to the limitation of the motor. The body system composed of two circuit breakers or isolating switches is also relatively large in volume. The electromagnetic operating mechanism plus the integrated bo...
