Automatic change-over switch

Abstract

The invention discloses an automatic change-over switch. Automatic change-over is realized through matching of a single circular shaft and a transmission plate; the transmission plate is rotationally arranged on the circular shaft, and a spring on one side presses against the transmission plate by using elasticity, so that the transmission plate on the other side is tightly matched with circuit breakers arranged below the transmission plate, and the structure ensures that different circuit breakers with height difference can be matched with the automatic change-over switch; a toggle support of which the position can be adjusted is arranged on the transmission plate, switching handles of the circuit breakers of different models have vertical position difference, and the vertical positions of the switching handles can be conveniently adjusted through the toggle support arranged on the transmission plate through screws to match the circuit breakers; and the in-place condition of the vertical position of the transmission plate is detected through a micro switch, so that the switch-on-off conditions of the circuit breakers can be learnt in real time.

Description

technical field [0001] The invention belongs to an electric switch, in particular to an automatic transfer switch. Background technique [0002] The automatic transfer switch is widely used in various places that require uninterrupted power supply, which realizes the automatic conversion of the power supply to ensure the reliability of the user's power supply. In order to realize the opening and closing conversion of two circuit breakers, what the known automatic transfer switch adopted at present is to be driven by the motor to drive the rotary switch to control the toggle brackets on both sides to move up and down alternately, and the toggle brackets drive the opening and closing of the circuit breaker switch. [0003] The overall structure of the existing automatic transfer switch is fixed, mainly because the positions of the front, rear, up and down cannot be adjusted after the toggle bracket is installed, but the circuit breakers have different models and specifications...

AI Technical Summary

Problems solved by technology

[0003]The overall structure of the existing automatic transfer switch is fixed, mainly because the position of the front, rear, up and down after the toggle bracket part is installed can no longer be adjusted, but the circuit breaker has a different Model specifications, one automatic transfer switch cannot be applied to circuit breakers of different models and specifications

In the prior art, a cover is added to the switch of the circuit breaker to cooperate with the toggle bracket, so that small-sized circuit breakers can also be used, but such a structure has higher requirements for the spatial position assembly of the automatic transfer switch and the circuit breaker. If the assembly is not good, it will directly affect the working quality of the circuit breaker switch, resulting in insufficient opening and closing, and failure to supply power
