Multi-power-supply change-over switch capable of avoiding simultaneous closing of circuit breakers

Abstract

The invention relates to the technical field of switch assemblies, and discloses a multi-power-supply change-over switch capable of avoiding simultaneous closing of circuit breakers, which comprises a turntable, a limiting disc fixedly connected to the front surface of the turntable, a connecting rod hinged to the side surface of the limiting disc, and a trigger mechanism hinged to one end, far away from the limiting disc, of the connecting rod, a clamping ring is movably connected to the outer side of the turntable, a communicating mechanism is fixedly connected to the outer side of the clamping ring, a clamping block is hinged to the inner side of the clamping ring, and a first limiting spring is movably connected to the side face of the clamping block; according to the multi-power-supply change-over switch capable of avoiding simultaneous closing of the circuit breakers, through cooperative use of the limiting disc and the triggering mechanism, only one circuit breaker is closed during power supply change-over, and under cooperation of the clamping ring and the clamping block, it is ensured that the change-over direction is uniform and stable, and the short-circuit situation caused by simultaneous closing of the multiple circuit breakers is avoided; and the service life of the equipment is guaranteed, and the use safety of people is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of switch assemblies, in particular to a multi-power conversion switch that prevents circuit breakers from being switched on at the same time. Background technique [0002] A switch refers to an electronic component that can open a circuit, interrupt the current, or cause it to flow to other circuits. There are many types of switches, and the most common one is the transfer switch. The transfer switch is a low-voltage switch that switches multiple circuits. The switch, also known as the combination switch, is an electrical appliance that changes the circuit from one set of connections to another set of connections. At present, the multi-power conversion switch on the market uses a motor-driven operating mechanism to control the toggle brackets on both sides to move up and down alternately. The opening and closing of the circuit breaker switch driven by the moving bracket is more complicated in cooperation wi...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a multi-power transfer switch that avoids the simultaneous closing of circuit breakers. It has the advantages of simple structure and avoids the short circuit caused by simultaneous closing of multiple circuit breakers. There are many toggle parts, which is prone to the problem of simultaneous closing of multiple circuit breakers
