A positive pressure type explosion-proof power distribution cabinet

Abstract

The invention discloses a positive-voltage explosion-proof distribution cabinet, which comprises a cabinet body, a transparent observation door and an acousto-optic alarm. An upper roof plate is fixedat the top of the cabinet body, and a lower mounting base is mounted at the bottom of the cabinet body. The transparent observation door is fixed on the front side of the cabinet body. A left supporting rod is mounted inside the left end of the upper roof plate, and a right supporting rod is mounted inside the right end of the upper roof plate. Protective covers are respectively fixed outside thetops of the left supporting rod and the right supporting rod. The positive-voltage explosion-proof distribution cabinet is equipped with protective covers which are driven to be opened by the reverserotation of the left supporting rod and the right supporting rod, so that the opened protective covers can protect the top of the whole positive-voltage explosion-proof distribution cabinet, and thewhole positive-voltage explosion-proof distribution cabinet can be used outdoors without the shelter of a canopy. Therefore, the scope of use environments of the positive-voltage explosion-proof distribution cabinet is widened, and the positive-voltage explosion-proof distribution cabinet can be well installed and used outdoors.

Description

technical field [0001] The invention relates to the technical field of positive pressure explosion-proof distribution cabinets, in particular to a positive pressure explosion-proof distribution cabinet. Background technique [0002] Positive pressure explosion-proof power distribution cabinet is a kind of power distribution switching equipment used in petrochemical industry, offshore drilling platform, metallurgy, medicine, light industry, textile, food, biological engineering, aerospace engineering and military facilities. The electric cabinet can protect the voltage of the circuit very well. At present, with the continuous development of science and technology and the different environments of use, there are various types of power distribution cabinets on the market. The positive pressure explosion-proof power distribution cabinet is a variety of distribution cabinets. A type of electric cabinet, the positive pressure type explosion-proof power distribution cabinet is comp...

Problems solved by technology

[0006] The purpose of the present invention is to provide a positive pressure type explosion-proof power distribution cabinet to solve the problem that the top of the traditional positive pressure type explosion-proof power distribution cabinet on the market does not have a cover protection structure proposed by the above-mentioned background technology, so that the positive pressure type explosion-proof power distribution cabinet When installed outdoors, it is easily affected by outdoor conditions and cannot be installed. The traditional wall-mounted positive pressure explosion-proof power distribution cabinet cannot store the mounting plate on the rear side, resulting in a large area occupied by the entire positive pressure explosion-proof power distribution cabinet.
