Description

Dampproofing formula regulator cubicle

Technical Field

The utility model relates to a dampproofing formula regulator cubicle belongs to electrical equipment technical field.

Background

The electrical cabinet is a cabinet which is formed by processing steel materials and used for protecting components from working normally, is indispensable equipment in power system facilities, and is widely applied to the fields of chemical industry, environmental protection industry, metallurgical system, nuclear power industry, fire safety monitoring, traffic industry and the like. In the use of regulator cubicle, numerous electrical components and the concentrated work of circuit in the regulator cubicle can produce a large amount of heats, need in time distribute away the heat that produces in the regulator cubicle, avoid electrical components and circuit ageing even burn out. At present, the heat dissipation measures are mainly to provide heat dissipation mesh holes on the side wall of the electrical cabinet, so that gas exchange inside and outside the electrical cabinet is realized, and heat accumulated in the electrical cabinet is quickly dissipated. However, since a certain amount of moisture is often contained in the air, especially in an area with high air humidity, the arrangement of the heat dissipation mesh on the electrical cabinet easily causes moisture in the air to enter the electrical cabinet, so that electrical components in the electrical cabinet are often in a high-heat and humid state, and further, the electrical components are rapidly aged, the service life of the electrical components is shortened, and even dangerous situations such as electric leakage and short circuit occur.

Among the prior art, the patent application with publication number CN108832512U discloses a dampproof device of regulator cubicle, including the electric cabinet body, the rigid coupling is equipped with the bar deckle board on the inner wall of the left and right sides of the electric cabinet body, vertically installs the heating rod in the bar deckle board, and the cover is equipped with the resistance wire on the heating rod, offers the thermovent of equipartition on the curb plate of the electric cabinet body is kept away from to the bar deckle board, has offered a plurality of louvre on the roof of the electric cabinet body shanghai. Through the heating effect of the resistance wire on the electric bar, heat is radiated into the electrical cabinet from the heat radiation port to remove the attached moisture on the electrical elements in the electrical cabinet body, and then the heat is radiated out through the heat radiation hole at the top. Although having reached dampproofing effect like this, nevertheless will heating the air in the regulator cubicle, not only will consume the electric energy, need regularly to the battery that provides the electric energy for the resistance wire charge, can also aggravate the state of lasting high temperature in the regulator cubicle, the condition that easily leads to electrical components's accelerated ageing, life to shorten appears.
