In the prior art, a communication and power cabinet is common equipment for industry and commerce, and is mainly used for intensively placing communication or power distribution and transformation equipment and the like. Along with the development of technology, the dependence on communication and power equipment in production and life is stronger, and the environment where the cabinet is located is more complex.
In industrial and commercial activities, heavy oil smoke places such as kitchens, painting workshops (such as coating processing of volatile materials such as plasticizers) and the like are more in electric appliances and have large power, and distribution/transformation and protection equipment is specially provided for converting three-phase alternating current into single phase or directly connecting three phases for various equipment. These distribution/transformation and protection devices are generally centralized in a cabinet. Because of the demands of heat dissipation and the like, the cabinet is provided with a heat dissipation air duct, and natural heat dissipation or forced heat dissipation and the like are adopted. The oil fume in the environment can be brought into the cabinet, the light person causes oil dirt to fall on the surface of the equipment, the heavy person can cause unsmooth operation of a mechanical mechanism of the equipment, accidents are caused, for example, an air switch and a handle of a leakage protection switch, after the oil dirt blocks a rotating mechanism of the handle, tripping action cannot be smoothly completed, protection failure is caused, or arcing occurs in the equipment.
Disclosure of Invention
Technical problem analysis: since the heat dissipation requirement of the cabinet is necessary, the smoke in the environment may cause damage to the equipment. The most effective method for removing the smoke is to introduce the smoke into water, cool the smoke, and make the small liquid beads in the smoke to be large liquid beads, and leave the small liquid beads in the water. However, for the cabinet, the occupied space does not allow the water tank to be added, and the flue gas is further supplied with more water after passing through the water, so that adverse effects are caused on equipment in the cabinet.
