Insulation box for transformer DC resistance tester

The invention discloses an insulation box for a transformer DC resistance tester. The insulation box comprises a box body formed by hinging a box base and a box cover; a heating plate, an intelligenttemperature controller and an electric leakage protection power supply plug, wherein the intelligent temperature controller and the electric leakage protection power supply plug are arranged at adaptive positions in the box cover. The transformer DC resistance tester is arranged in the box base, and at least one heating plate is arranged at the adaptation position of the side wall adjacent to thetransformer DC resistance tester. The electric leakage protection power supply plug, the intelligent temperature controller and the heating plate are connected in series through a wire. According to the requirement for the running environment temperature of the instrument, the temperature adjusting is carried out, the heat preservation in the box can be carried out, the temperature adjusting speedis high, the size is small
