Abstract

The invention discloses an electric leakage protection switch for a power plant. The electric leakage protection switch comprises a moving device, a supporting device and a pressing device, wherein the moving device comprises a fixed steel plate, a first fixed plate, a V-shaped folding plate and a second fixed plate; the supporting device comprises a KT plate and a transparent cover; the pressingdevice comprises a stretching spring, a pressing column and an electric leakage protection switch, wherein the fixed steel plate is fixed on the wall of the power plant, and the first fixed plate is welded to one side of the fixed steel plate; one side of the first fixed plate is rotationally connected with the V-shaped folding plate through a shaft pin; and one side of the V-shaped folding plateis rotationally connected with the second fixed plate through a shaft pin. The position of the electric leakage protection switch can be changed through the V-shaped folding plate, and the electric leakage protection switch can be moved out of a meter box when the electric leakage protection switch is damaged, so that the use flexibility is relatively high, influence to maintenance by complex wireharnesses in the meter box is avoided, unloading of the switch is also avoided, the maintenance time is saved, and convenience is brought to the maintenance.

Description

Technical field [0001] The invention relates to the field of electrical appliance protection devices, in particular to a leakage protection switch for power plants. Background technique [0002] The leakage protection switch is used to effectively protect the direct and indirect contact electricity of the low-voltage power grid. It can also be used as a phase failure protection for three-phase motors. It has single-phase and three-phase, as a way to prevent personal electric shock and leakage A grounding protection device that causes an accident. When the leakage current of the circuit or electrical equipment is greater than the set value of the device, or people or animals are in danger of getting an electric shock, it can act quickly to cut off the accident power supply, avoid the expansion of the accident, and protect the person and equipment As one of the important equipment of the power plant, the leakage protection switch plays an important role. However, the current leakag...
