Abstract

The invention relates to an automatic change-over switch electric appliance, and the electric appliance has a fool-proof function, is simple in structure and is lower in cost. The electric appliance comprises an operating panel; a photoelectric coupling module which is disposed at one side of the operating panel; a driving part which is coupled to the photoelectric coupling module, and can move between a first limit position and a second limit position, so as to prompt the photoelectric coupling module to output an electric signal; and a controller which is used for receiving the electric signal. When the driving part is located at the first limit position, the electric appliance is in an automatic mode, and a hand-operated hole on the operating panel is sheltered. When the driving part is located at the second limit position, the electric appliance is in a manual mode, and the hand-operated hole on the operating panel is opened.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to an automatic transfer switch electrical appliance. Background technique [0002] Automatic transfer switching equipment (ATSE) is mainly suitable for emergency power supply systems of low-voltage power distribution networks, and is used to switch between main and backup power sources. Since the automatic transfer switch has two working modes, automatic and manual, in order to ensure that the automatic transfer switch can work safely and reliably, it is usually necessary to set up a fool-proof structure, so as to prevent the automatic transfer switch from being operated manually when it is in the automatic mode. Operate the automatic transfer switch to avoid damage to the circuit and the personal safety of the operator due to misuse. [0003] In order to overcome the above-mentioned defects, most automatic transfer switch appliances in the prior art use a micro-switch detectio...
