Problems solved by technology

[0002] It is often necessary to open the main gate of the power distribution panel on the user side when installing and connecting the low-voltage metering distribution panel and replacing the low-voltage current transformer, and then replace the low-voltage current transformer on the busbar, and often when replacing the low-voltage current transformer. Tools such as wrenches are used. Due to the small space above and below the distribution panel, and the distance between the installation position of the transformer and the live part of the upper pile head of the main gate of the distribution panel is small, there is a certain unsafe factor when changing the transformer.
[0003] Usually, when replacing the low-voltage current transformer, hang a pair of grounding wires on the pile head of the main gate of the metering power distribution panel, and hang a pair of grounding wires on the outlet side of the metering power distribution panel. After the work is completed, the two pairs of grounding wires need to be removed. But in fact, when the power is transmitted after the work is completed, the staff will forget to remove the grounding wire, resulting in closing with grounding, which is prone to safety accidents

Abstract

The invention discloses an anti-misoperation device of a low-voltage measuring cabinet. The anti-misoperation device comprises an insulation isolating bracket capable of being arranged on a knife switch of a distribution board switch blade so as to effectively isolate an electrified part on the pile head of the switch blade, and the insulating isolation bracket is connected with an insulation connecting rope capable of being connected with a grounding wire. In the invention, the insulation isolating bracket is arranged on the knife switch of the distribution board switch blade and can effectively isolate the electrified part on the pile head of the switch blade, so that the anti-misoperation device can prevent the low-voltage measuring cabinet from having misoperation when an electric energy meter or a current transformer is replaced when the power is turned off, the insulation connecting rope prompts disassembly of the grounding wire, and thus closing with grounding can be effectivelyprevented.
