The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. Insulation resistance detection is very important for the distribution cabinet. If the insulation resistance is missing, the distribution cabinet is in a dangerous state or an unqualified and damaged state. Therefore, a regular detection device is required. The existing detection device needs to disassemble and detect the control cabinets of each distribution cabinet separately for each detection. The process is complicated and the detection effect is slow.
