Abstract

The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet with an overheating protection structure, and solves the problems that internal high temperature is not easy to timely and effectively discharge and internal components are not easy to cool when an electrical cabinet in the prior art is used. The electrical cabinet specifically comprises an electrical cabinet, multiple sets of first heat dissipation openings are formed in the two sides of the electrical cabinet in a penetrating mode, blocking pieces are rotationally arranged in the first heat dissipation openings, driving assemblies are arranged on the opposite faces in the electrical cabinet, the driving assemblies are movably connected with the blocking pieces through linkage pieces, and protection frames are arranged on the opposite faces in the electrical cabinet. A plurality of groups of mounting pieces are arranged between the protection frames up and down, and a plurality of groups of second heat dissipation openings are formed in the two sides of the electrical cabinet and located below the first heat dissipation openings in a penetrating mode. A stop block is arranged at the second heat dissipation opening. According to the invention, the interior of the electrical cabinet can be timely and effectively cooled, normal use of the electrical cabinet can be conveniently recovered, and damage to components of the electrical cabinet, even safety accidents such as fire disasters caused by high temperature in the electrical cabinet during use can be prevented.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to an electrical cabinet with an overheating protection structure. Background technique [0002] Electrical cabinets are mainly used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. It is a cabinet made of steel to protect components and circuits from normal operation. When the electrical cabinet is in use, due to the large number of internal electrical components, the electrical components will generate relatively large heat during long-term use. Heat dissipation, and some electrical cabinets are equipped with overheating protectors. When the heat inside the cabinet is too high to dissipate heat in time, in order to prevent the internal components and lines of the electrical cabinet from being damaged due to high temperature, or even a fire...
