The invention discloses a high-
voltage switch cabinet with a protection structure, and relates to the technical field of switch cabinets, and the high-
voltage switch cabinet comprises a composite mechanism. According to the
punching device for knapsack
processing and the
punching method, through the design of a composite mechanism, the whole device can be driven to slide in the
processing mechanism through the bearing mechanism, checking, cleaning and replacement are facilitated,
wind power is generated through a draught fan, air is supplied into the
processing mechanism, and therefore the ventilation and heat dissipation effects are achieved; equipment faults caused by too high
internal temperature are avoided, potential safety hazards are reduced, the service life of equipment is prolonged, the equipment is protected, wind blowing drives a rotating mechanism to rotate on the surface of a
metal ring, so that the rotating
friction effect is generated, the electrostatic effect is generated through friction, dust in air is adsorbed, and the dust removal effect is improved. Dust entering the equipment is reduced, equipment damage caused by
dust pollution is prevented, air passes through the filtering opening, dust entering is further reduced, and the ventilation and heat dissipation quality is improved.
