Electricity is a general term for disciplines or engineering fields such as the production, transmission, distribution, use of electrical energy and the manufacture of electrical equipment. It is a science that creates, maintains and improves limited space and environment by means of electrical energy, electrical equipment and electrical technology, covering three aspects of electrical energy conversion, utilization and research, including basic theory, application technology, facilities and equipment. At present, most of the electricity on the market is controlled and distributed through the power distribution cabinet, so the power distribution cabinet can be said to be the most important core of electrical use, but the temperature of the power distribution cabinet will become higher and higher in the long-term use process. Electrical accidents such as short circuit are prone to occur, but most of the protection devices of power distribution cabinets on the market are relatively simple, do not have heat dissipation function, and some have heat dissipation function. Under the long-term use of the fan, the external dust, oil and harmful gases will also follow. When it enters the power distribution cabinet, it is electrostatically adsorbed on the surface of the circuit board. Over time, it will corrode components and lines, and at the same time affect its heat dissipation. The accumulated dust can also cause a short circuit in the high-voltage part of the circuit board when wet. The longer the working time of the power distribution cabinet, the more prominent the above-mentioned problems. When accumulated to a certain extent, it will cause a sudden failure of the control part. Therefore, it is necessary to improve the existing technology to solve the above-mentioned problems.
