Abstract

The present invention provides a dual power automatic transfer switch, which includes a housing, a control box and a switch group, the switch group includes several static contact assemblies and several corresponding moving contacts, and each of the static contact assemblies includes Load connection terminal, I-way connection terminal and II-way connection terminal, each moving contact is rotatably arranged between the load connection terminal, I-way connection terminal and II-way connection terminal of the corresponding static contact assembly through a rotating shaft Each of the moving contacts has at least two electrically connected moving contacts, and the moving contacts rotate in forward and reverse directions under the control of the control box, so that two of the moving contacts on the moving contacts The movable contact is selectively connected to the load connection terminal and the I-way connection terminal, or connected to the load connection terminal and the II-way connection terminal. By optimizing the structural design, the safety performance of the electrical equipment is improved, and the stability of the automatic transfer function of the dual-power automatic transfer switch is guaranteed.

Description

technical field [0001] The invention relates to the field of power switches, in particular to a dual power supply automatic transfer switch. Background technique [0002] The dual power automatic transfer switch is suitable for the power supply system, which is composed of one or several transfer switch electrical appliances and other necessary electrical appliances, used to detect the power supply circuit, and automatically transfer each one or more load circuits from one power supply to another A power supply for electrical appliances. When the main power supply fails or fails, the dual power supply automatic transfer switch is automatically put into the backup power supply so that the equipment can still operate normally, so that it can not only prevent the faulty power supply from supplying power to the load, but also reliably select a qualified power supply to put it into normal operation. , to ensure the continuous and reliable operation of the main load. The dual-po...
