Abstract

The invention discloses a transfer switch, which comprises a main shell. A circuit breaker assembly and an electronic assembly are arranged in the main shell; the electronic assembly controls a driving motor; the driving motor controls a tension rod through controlling a clutch mechanism; the tension rod drives a moving contact to perform on-off switching; the tension rod is correspondingly provided with a guiding plate; a guiding groove is arranged on the guiding plate; a guiding block is fixed on the tension rod; the guiding block slides along the guiding groove; the other side, corresponding to the tension rod, of the guiding plate is provided with a trigger switch; the trigger switch is connected with the electronic assembly; the trigger switch is arranged in correspondence with the guiding block; during the tension rod action process, the moving contact and a static contact are switched between on and off; and during the moving contact switching process, the guiding block on the tension rod is switched between touching the trigger switch and separating from the trigger switch. In the transfer switch, the tension rod pulling the moving contact has a more stable structure, state information can be timely transmitted to the electronic assembly through the trigger switch, and the electronic assembly can perform display and control according to a scheduled procedure conveniently.

Description

technical field [0001] The invention relates to a transfer switch. Background technique [0002] A traditional power transfer switch generally includes a main housing, in which a circuit breaker assembly and an electronic assembly are installed, and a motor drives a pull bar on the circuit breaker, and the pull bar drives the moving contact to move. However, the movement trajectory of the tie bars is not stable enough, which easily affects the timely switching of the circuit breaker. Contents of the invention [0003] In view of the deficiency of the background technology, the technical problem to be solved by the present invention is to provide a changeover switch, which can guide the pull bar stably and transmit the state of the moving contact to the electronic component in time. [0004] For this reason, the technical proposal of the present invention is: change-over switch, comprise main housing, circuit breaker assembly and electronic assembly are installed in main h...
