Problems solved by technology

[0003] In the prior art, most of the methods for outdoor low-voltage switchgear to prevent rain, dust, ventilation and cooling use traditional ventilation windows, or install axial flow fans to force convection ventilation, which still has a significant impact on the electrical performance and safety of the switchgear. There are hidden dangers

specific Embodiment approach

[0018] The rain-proof and ventilated structure of the 0.4kV outdoor low-voltage complete switchgear of the present invention, its preferred specific implementation mode is:

[0019] It includes a front door panel, a rear door panel, a top cover and a bottom panel, the front door panel and the rear door panel respectively include a door panel and a door panel lining that are welded to each other, the lower part of the door panel is provided with louvers, and the upper part of the door panel lining is provided with louvers;

[0020] The upper surface of the top cover is provided with a slope, the inner surface of the top cover is provided with a top cover lining plate and an air duct bending plate, and the edge of the top cover is provided with a vent in the shape of a bell mouth.

[0021] The louvers on the lower part of the door panel open outwards, the louvers on the upper part of the door panel lining open inward, and the lower edge of the door panel lining is aligned with th...

specific Embodiment

[0025] Such as Figure 1a to Figure 4b Shown is the door panel, lining, and door panel welding of the switchgear with rainproof ventilation and cooling. The key point is that the shutters of the door panel are at the lower part and open outward. The lining louvers are on the upper part and open inward. In this way, the outside fresh air enters through the lower louvers of the door panel, moves upward through the upper louvers of the lining and enters the inside of the switchgear, and is exported to the outside of the switchgear through the top cover to form a natural fresh air loop to achieve cooling. The lower edge of the inner lining is aligned with the lowermost edge of the shutter of the door panel and then welded. In this way, external rainwater or splash water will flow out along the shutter at the lower part of the door panel after entering the door, and will not enter the equipment to achieve the rainproof function.

[0026] Such as Figure 5 Shown is the top cover, t...

Abstract

The invention discloses a rain-proof ventilation structure of 0.4 kV outdoor low-voltage complete switch equipment. The structure comprises a front door plate, a rear door plate, a top cover and a bottom plate, the front door plate and the rear door plate each comprise a door plate and a door plate lining which are welded to each other, shutters are arranged on the lower portions of the door plates, and shutters are arranged on the upper portions of the door plate linings; the shutters on the lower portions of the door plates are opened outwards, the shutters on the upper portions of the doorplate linings are opened inwards, and the lower edges of the door plate linings are aligned with the lowermost edges of the shutters of the door plates and then welded. A slope is arranged on the topcover, a top cover lining plate and an air duct bent plate are arranged on the inner face of the top cover, and a horn-mouth-shaped ventilation opening is formed in the edge of the top cover. Ventilation opening are formed in bottom plate. Hot air in the switch equipment can be guided out, and external rainwater is prevented from splashing into the equipment. Therefore, the low-voltage switch equipment is safer and more reliable to use, and the performance safety of the switch equipment can be prevented from being affected by a severe outdoor environment.

Description

technical field [0001] The present invention relates to a 0.4kV outdoor low-voltage complete switchgear (hereinafter referred to as "switchgear"), in particular to a rainproof and ventilated structure of a 0.4kV outdoor low-voltage complete switchgear. Background technique [0002] With the rapid development of the power industry, the application of outdoor low-voltage switchgear is becoming more and more extensive. Especially during the use of outdoor switchgear, it is still a technical problem to do a good job of rainproof, dustproof, ventilation and cooling of the switchgear without lowering the safety standards. [0003] In the prior art, most of the methods for outdoor low-voltage switchgear to prevent rain, dust, ventilation and cooling use traditional ventilation windows, or install axial flow fans to force convection ventilation, which still has a significant impact on the electrical performance and safety of the switchgear. There are hidden dangers. Contents of t...
