Abstract

The invention discloses a constant-temperature power distribution cabinet, which comprises a cabinet body with an opening in the front end and cabinet doors, wherein the cabinet doors are connected to the front end of the cabinet body through hinges; a slope plate which is high in the middle part and low in two sides is formed at the bottom part in the cabinet body; a stepper motor is arranged at the upper part, at the middle position of the slope plate, of the lower part of a rear cabinet plate, at the rear side of the cabinet body, in the cabinet body; an output shaft of the stepper motor is connected with a refrigeration piece assembly which is horizontally arranged along the frontward-backward direction of the cabinet body; a front baffle plate is arranged at the lower part of the front side of the cabinet body; a first flow guide plate is fixedly connected to the left upper part of the refrigeration piece assembly in the cabinet body; a baffle plate is fixedly connected to the right side of the refrigeration piece assembly in the cabinet body; an upper air inlet is formed in the left side, between the first flow guide plate and the second flow guide plate, of the cabinet body; an upper fan is arranged in the upper air inlet; the outer wall on the left side of the cabinet body is connected with an upper air inlet plate above the upper air inlet; and exhaust openings are formed in the left side and the right side of the upper part of the cabinet body. The constant-temperature power distribution cabinet is simple and compact in structure and suitable for various complicated working environments.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a structure of a constant temperature power distribution cabinet. Background technique [0002] The power distribution cabinet is to assemble switchgear, measuring instruments, etc. in a closed or semi-closed metal cabinet according to the requirements of electrical wiring. The Chinese patent with the document number CN104613672A discloses a semiconductor high-voltage cabinet dehumidification device. The shape of the invention is a sheet-like body made of semiconductor refrigeration sheets, and its heating surface is attached to the high-voltage power distribution cabinet through heat-conducting silicone grease. On the inner wall of the metal shell, its cooling surface is close to a layer of metal film. The outer surface of the metal film is a polished plane. There is an inclined bus bar on the plane. The bus bar leads to the high-voltage power distribution through t...
