A dustproof and rainproof medium frequency power supply cabinet

Abstract

The utility model discloses a dustproof and rainproof medium frequency power supply cabinet, which relates to the technical field of power supply cabinets, and comprises a power supply cabinet body and heat dissipation grooves symmetrically arranged on both sides of the power supply cabinet body. A clamping plate is elastically pulled by a tightening spring to stably fix the dust cover, which is convenient for subsequent disassembly and installation. The dust cover covers the heat dissipation groove, which not only plays a role of dustproof protection, but also plays a role of shielding rainwater splashing in. When the rainwater is heavy, the splashing rainwater drops into the waterproof cover and is collected by it. The waterproof cover is provided with waterproof cover ventilation holes, and the openings are gradually increased from bottom to top. While collecting the rainwater, the normal heat dissipation of the device will not be hindered. When the water level detection head detects that the water level in the waterproof cover reaches a predetermined point, a signal is sent to light up the alarm light, and the staff can drain the water from the waterproof cover through a drain pipe, thereby further improving the waterproof effect of the device when it encounters heavy rain when used outdoors.
