AI Technical Summary

Problems solved by technology

The energy storage mechanism used to stop the motor is not only relatively complex in structure, but also has multiple rocker arms and connecting rods, which is easy to cause jamming, so it is easy to cause two different power sources to run in parallel, resulting in burnout of the load equipment. or cause interruption of power supply

Abstract

The invention discloses an automatic PC-level dual-power changeover switch. The changeover switch comprises a shell, a motor arranged in the shell, an operating mechanism and a contact system, wherein the motor is connected with the operating mechanism which is connected with the contact system; an operating system can realize storage transmission by combining cams with clamping pieces, the cams are linked with the moving contacts of the contact system, wire input and output terminals of the contact system are respectively arranged on both sides of the shell to realize a connection mode of entering at top and leaving at bottom, one moving wire input contact is shifted between two wire input terminals, and moving wire output contacts on both sides rotate along the moving wire input contact and are respectively connected with one wire output terminal. The changeover switch is simple in structure, convenient to connect, and steady in performance.

Description

technical field [0001] The invention relates to a dual power supply automatic switching switch, in particular to a PC-level dual power supply automatic switching switch. Background technique [0002] The dual power automatic transfer switch is used in the power supply system when the main power supply fails, it can not only prevent the faulty power supply from supplying power to the load, but also reliably select a qualified power supply for normal operation to ensure uninterrupted power supply. Generally, places that are more important to use, such as hospitals, airports, and docks, rely on dual power automatic transfer switches to provide continuous power supply. [0003] PC-level dual-power automatic transfer switch is generally packaged in a complete shell, and its wiring is two-way power supply, one for use and one for backup, and each other is for backup. It is composed of two load isolation switches superimposed and combined with a controller. It has mechanical linkag...
