Rainproof electrical installation cabinet

Abstract

The invention discloses a rainproof electrical installation cabinet, which comprises a bottom plate, wherein a cabinet body is welded to the top outer wall of the bottom plate, a partition plate is welded to the inner wall of the cabinet body, a storage cavity is formed below the partition plate, semiconductor refrigeration chips distributed at equal intervals are welded to the inner wall of the bottom of the cabinet body, a refrigerant is contained in the storage cavity, an air inlet groove penetrating through the bottom plate is formed in the middle of the partition plate, an air inlet fan is welded to the inner wall of the air inlet groove, a water suction box welded into the air inlet groove is arranged below the air inlet fan, damping springs and damping sponges are distributed on theouter wall of the top of the partition plate at equal intervals, and a mounting plate slidably connected with the inner wall of the cabinet body is welded to the tops of the damping springs and damping sponges. According to the invention, an air inlet fan sucks in external air, a dustproof net and a water suction box filter and adsorb dust impurities and moisture, a refrigerant cools the air, anair outlet fan discharges heat, the heat dissipation and cooling efficiency is improved, the fan increases air flow, a humidity sensor prevents rainwater from entering the cabinet body, and a drying net box absorbs the moisture in the air.

Description

technical field [0001] The invention relates to the technical field of installation cabinets, in particular to a rainproof electrical installation cabinet. Background technique [0002] The electrical installation cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit.

[0002] The electrical installation cabinet is a group of electrical equipment for transmission and distribution that is installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has simple structure, small size, It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises, etc., mainly for chemical industry. Industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc., the electrical cabinet of the prior art has a single structure, and the electrical cabinet with cooling holes is easy to get wet inside in rainy and snowy weather. Affect the operation of electrical equipment, and electrical cabinets without cooling holes are prone to short circuit or even spontaneous combustion due to internal heat accumulation. , Dust easily enters the interior of the electrical installation cabinet, affecting the service life of the internal parts of the electrical installation cabinet, and the climate is relatively hot in summer, the moisture in the air is large, the internal parts of the electrical installation cabinet are easy to be damp, and the circuit components inside the electrical installation cabinet Heat is generated during operation, and it is obviously not enough to simply rely on the air holes around the shell of the electrical installation cabinet for heat dissipation and ventilation
