Background technique

The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. Some power distribution cabinets are installed indoors, while others are installed outdoors. For outdoor power distribution cabinets, after a long period of rainwater washing, the interior will easily get damp, which will make the components inside the power distribution cabinet damp, and will A short circuit will occur, which will damage the electrical appliances connected to the power distribution cabinet and cause unnecessary losses. When the interior of the power distribution cabinet is damaged, maintenance workers need to open the power distribution cabinet for maintenance, which will cause rainwater to enter the power distribution cabinet. In the cabinet, it will affect the normal operation of the internal components of the power distribution cabinet, and it will also cause electric shock.
