The utility model relates to an apparatus placing box, especially relates to a test apparatus combined box of a more than 110 kV transformer, mainly composed of an angle steel, a rubber insulating pad and a stainless steel plate. A framework structure is welded via the angle steel, the stainless steel plate is arranged on the outside of the framework, and the rubber insulating pad is arranged on the bottom of the framework; a transformer and a tool box are arranged on one side of the interior of the framework, an illumination device and an air-conditioner are arranged in the middle, and an insulating rod, a conducting wire box and a tool box sampling bottle are arranged on the other side of the interior of the framework. The beneficial effects of the utility model are that various devices are assembled as one, soft foam materials are filled around the devices in the test apparatus combined box to prevent isolating devices from contacting with a table-board directly, thereby solving the damage brought by the bumpiness of devices; the exterior of the combined box employs the stainless steel plate, solving the effects on the test measurement data brought by the external environment interferences, reducing the device truck loading, truck unloading and assembly time, shortening the test time, and improving the working efficiency.
