Embodiment 1

[0022] Such as Figure 1-3 As shown, an anti-condensation type high heat dissipation outdoor power distribution cabinet includes a cabinet body 1, a photovoltaic panel 2 is installed on the upper end of the cabinet body 1, and a plurality of first ventilation openings are provided on the side walls on both sides of the cabinet body 1 3. The inner bottom surface of the cabinet body 1 is equipped with a raised seat 4, and the upper end of the raised seat 4 is installed with a waterproof cover 5 extending in the vertical direction of the cabinet body 1 and arranged in a cylindrical shape. The waterproof cover 5 is arranged in a cylindrical shape, and the waterproof cover 5. It is composed of two semi-arc-shaped cover panels spliced ​​end to end, which is convenient for assembly and disassembly. There are multiple second ventilation openings 6 inside the waterproof cover 5, multiple first ventilation openings 3 and multiple second ventilation openings 6 All are arranged in a stagg...

Embodiment 2

[0029] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that a ring gear 13 is fixedly sleeved on the side wall of the outer ring of the waterproof cover 5, and the ring gear 13 is arranged in a long cylindrical shape, and the screw nut 10 is installed coaxially on the outside. There is a gear 14 which meshes with the ring gear 13 .

[0030] In this embodiment, when the screw nut 10 rotates, the gear 14 is driven to rotate synchronously, and then the ring gear 13 meshed with it drives the waterproof cover 5 to rotate, and under the action of inertial force, the water condensed on the inner wall of the waterproof cover 5 is promoted. The slipping of the beads is beneficial for the drops of water to drip downwards and be discharged out of the cabinet body 1 through the drainage holes 12 .

Abstract

The invention belongs to the field of power distribution cabinets, particularly to an anti-condensation high-heat-dissipation outdoor power distribution cabinet. The cabinet comprises a cabinet body,wherein the upper end of the cabinet body is provided with a photovoltaic panel; a plurality of first ventilation openings are formed in the side walls of the two sides of the cabinet body; an ascending flanged base is mounted on the inner bottom surface of the cabinet body; the upper end of the ascending flanged base is provided with a waterproof cover which extends along the vertical direction of the cabinet body and is arranged in a cylindrical shape; a plurality of second ventilation openings are formed in the waterproof cover; a plurality of the first ventilation openings and the plurality of second ventilation openings are formed in a staggered mode; and a plurality of electronically-induced temperature difference pieces are embedded in the waterproof cover at equal intervals, the refrigeration faces of the electronically-induced temperature difference pieces are close to the inner ring of the waterproof cover, and the heating faces of the electronically-induced temperature difference pieces are close to the outer ring of the waterproof cover. The waterproof cover can effectively prevent rainwater from entering the cabinet body to corrode electrical components, moisture in the air in the cabinet body can be condensed into water drops on the refrigeration faces of the electronically-induced temperature difference pieces, the water drops converge and are rapidly dischargedout of the cabinet body, and thus, the water drops are effectively prevented from being condensed and attached to the surfaces of electrical components.

Description

technical field [0001] The invention belongs to the field of power distribution cabinets, in particular to an anti-condensation type high heat dissipation outdoor power distribution cabinet. Background technique [0002] The upper limit of the ambient temperature of the electrical equipment designed and manufactured according to the national standard should not exceed 40°C, and the operating distribution box exposed to the scorching sun in midsummer, due to the direct sunlight, the reflection of heat from the concrete floor and the equipment inside the box The heat generated by itself, sometimes the temperature in the box exceeds 60°C. Such a high temperature can easily cause the insulation of electrical coils and lead wires to age and breakdown and burn out; the contact resistance of electrical contacts increases due to excessive temperature, and the contact resistance increases It also intensifies the heating, and such a vicious circle will eventually lead to the burnout o...
