The invention relates to the field of the electric appliance cabinet voltage resistance, in particular to an electric appliance cabinet voltage resistance test device, which comprises a pressure tester, wherein the pressure tester comprises an equipment cavity and a test cavity, the equipment cavity is positioned on the top of the pressure tester, the test cavity is positioned right below the equipment cavity, the outer wall of the front side of the top of the test cavity is provided with an upper sliding rail, the outer wall of the front side of the bottom of the test cavity is provided witha lower sliding rail, a sliding door is connected between the upper sliding rail and the lower sliding rail in a sliding manner, the outer wall of the front side of the sliding door is provided with an observation window, and a door handle is fixedly arranged on the outer wall of one side of the sliding door close to the observation window through a bolt. The electric appliance cabinet voltage resistance test device has the beneficial effects that the electric appliance cabinet needing pressure measurement test can be effectively fixed, so that electric appliance cabinet that needs pressure measurement is more firmly and stably fixed, the accuracy of pressure measurement data is improved, and the phenomenon of inaccurate pressure measurement data caused by unstable fixation of the electricappliance cabinet in the pressure measurement test process is avoided.
