The utility model belongs to the field of a safety protection tool of an electric power system, and specifically relates to a metering cabinet door safety protection plate. The metering cabinet door safety protection plate comprises an upper insulation plate body and a lower insulation plate body. A lower insulation slideway and an upper insulation slideway are respectively fixed at the left two sides of the lower insulation plate body and the right two sides of the upper insulation plate body; the upper insulation plate body is disposed in a chute at the upper portion of the lower insulation slideway; the lower insulation plate body is disposed in a chute at the lower portion of the upper insulation slideway; the four corners of the lower insulation plate body and the right-side two corners of the upper insulation plate body are each provided with an adsorption fixing support legs; the adsorption fixing support legs are composed of insulation columns and adsorption magnets; and the upper ends of the insulation columns are fixedly connected with the insulation plate bodies, and the adsorption magnets are fixed at the lower ends. The advantages are as follows: the structure is simple and reasonable; an insulation plate surface formed through the upper insulation plate body and the lower insulation plate body can protect personal safety and also can protect equipment in a cabinet from extrusion damage; and through adjusting the relative positions of the upper insulation plate body and the lower insulation plate body and the length of the adsorption fixing support legs, the metering cabinet door safety protection plate can be adaptive to different metering cabinet doors, and the application scope is wide.
