The invention discloses a high-voltage frequency converter power unit cabinet with a self-circulation cold air device, which comprises a cabinet body and a case, wherein the top of the case is fixedlyconnected with the bottom of the cabinet body; the interior of the cabinet body is fixedly connected with an inner box through a cushion block; and a cavity is arranged between the inner box and thecabinet body. According to the high-voltage frequency converter power unit cabinet with a self-circulation cold air device which relates to the technical field of frequency converter unit cabinets, arotatable wind shield is arranged above the high-voltage frequency converter; during work, the wind shield is put down, the space above the high-voltage frequency converter can be separated, air flowtransversely flowing between the first vertical plate and the second vertical plate must pass through a gap in the high-voltage frequency converter and can not pass across the exterior of the high-voltage frequency converter, heat in the internal gap of the high-voltage frequency converter can be led out to the maximum extent, the heat dissipation effect is further guaranteed, the wind shield canbe rotated to a horizontal state and is absorbed by a permanent magnet, and assembly and disassembly of the high-voltage frequency converter are not affected.
Description
technical field [0001] The invention relates to the technical field of frequency converter unit cabinets, in particular to a high-voltage frequency converter power unit cabinet with a self-circulating cooling air device. Background technique [0002] Inverter control cabinet (inverter electric control cabinet / electrical control cabinet) can be widely used in pumps, fans, air compressors, rolling mills, injection molding machines, belts, etc. in metallurgy, chemical industry, petroleum, water supply, mining, building materials, and motor industries. Transport aircraft and other medium voltage electrical equipment. The frequency conversion cabinet adopts a closed cabinet structure, and the protection grades are generally IP20, IP21 and IP30. Direct operation, local and remote control or PC / PLC communication control can be set according to needs, with various intuitive display functions. The frequency converter is a special supporting product of the frequency conversion cabin...
