Abstract

The invention relates to the technical field of electrical accessory equipment, and discloses a change-over switch auxiliary device for avoiding short circuit caused by simultaneous closing of multiple circuit breakers. The device comprises a shell, a fixed rod is fixedly mounted on the inner wall of the shell, and a reverse rotation control mechanism is fixedly mounted on the front surface of the fixed rod; and an intermittent gear is fixedly installed on the outer side of the reverse rotation control mechanism, and a driven gear is rotationally connected to the front face of the fixing rod. The change-over switch auxiliary device for avoiding short circuit caused by simultaneous closing of multiple circuit breakers is simple in structure, when one circuit breaker is closed, the other circuit breaker is opened under the action of the compression spring, simultaneous closing easily caused by up-and-down alternate movement is avoided, personnel safety is guaranteed, and meanwhile, the working stability of equipment is improved. And moreover, the device can be suitable for mutual switching among multiple circuits, the situation that the change-over switch cannot be used due to failure of a mechanism on one side is prevented, the cost is saved to a certain extent, and the working efficiency of equipment is improved.

Description

technical field [0001] The invention relates to the technical field of electrical accessory equipment, in particular to an auxiliary device for a transfer switch that avoids short circuit caused by simultaneous closing of multiple circuit breakers. Background technique [0002] The transfer switch is one of the more common electrical accessories. It is widely used in various places that require uninterrupted power supply. It realizes the automatic conversion of the load line between multiple power sources to ensure the reliability of the user's power supply. The transfer switch consists of multiple In electrical equipment, it is mostly used for infrequently connecting and breaking circuits, connecting power sources and loads, etc. [0003] However, the existing transfer switch has a complex structure and many parts. Not only is it time-consuming to assemble during production, but it is also prone to simultaneous closing, resulting in a circuit breaker and even endangering th...
