Outdoor high-voltage power distribution cabinet

Abstract

The invention discloses an outdoor high-voltage power distribution cabinet which comprises a cabinet body, the side wall of the cabinet body is provided with an air inlet and an air outlet which penetrate in the thickness direction, the air outlet is connected with a ventilation pipe, a forced ventilation assembly is arranged in the ventilation pipe, and a rainproof cover is arranged at the top ofthe ventilation pipe. In the using process of the outdoor high-voltage power distribution cabinet, the forced ventilation assembly can pump out air in the cabinet body from the exhaust port, and meanwhile low-temperature air rushes into the air inlet to enter the cabinet body. Forced ventilation can reduce the temperature in the cabinet body, thereby reducing the temperature difference between the interior and exterior of the cabinet body, and reducing the condensation risk in the cabinet body.

Description

technical field [0001] The invention relates to the technical field of electric power protection equipment, in particular to an outdoor high-voltage power distribution cabinet. Background technique [0002] Outdoor high-voltage power distribution cabinets are usually used in outdoor cable distribution boxes, knife switch cabinets and other equipment in power systems. During the use of outdoor high-voltage power distribution cabinets, issues such as anti-condensation, anti-dust, and heat dissipation need to be considered. Existing outdoor high-voltage power distribution cabinets use high-standard protection levels to prevent dust and moisture. Although dust and rainwater can be prevented from entering the cabinet, when the external humidity environment reaches saturation in the air, there will be a large amount of dust in the air. Water vapor, water vapor will enter the cabinet with the air. The temperature inside the cabinet is often higher than the external environment. W...

Problems solved by technology

Existing outdoor high-voltage power distribution cabinets use high-standard protection levels to prevent dust and moisture. Although dust and rainwater can be prevented from entering the cabinet, when the external humidity environment reaches saturation in the air, there will be a large amount of dust in the air. Water vapor, water vapor will enter the cabinet with the air

The temperature inside the cabinet is often higher than the external environment. When there is a temperature difference between the inside of the cabinet and the outside of the cabinet, condensation will occur on the side wall of the outdoor high-voltage power distribution cabinet, and the condensation will easily cause accidents when it drips on the surface of the power equipment.
