Problems solved by technology

[0004] In addition, the air in most parts of southern my country is humid. In addition, switchgears are needed in general engineering sites. Traditional switchgears are difficult to take into account waterproof and moisture-proof due to heat dissipation, and it is difficult to adapt to the working environment of humid air. It is prone to failure and has a sh

Abstract

The invention relates to a positive-pressure space switch cabinet. The cabinet comprises a cylindrical main cabinet body and a plurality of branch cabinet bodies arranged in the main cabinet body; anexhaust port is formed in the upper side wall of the main cabinet body, an air inlet is formed in the side wall of the main cabinet body below the exhaust port; the exhaust port and the air inlet areseparated by an annular upper partition plate; a blower device is arranged in the center of the lower part of the main cabinet body and blows air upwards; annular air suction ports with downward openings and an annular steam suction port are formed in the upper part in the main cabinet body; the air suction ports and the steam suction port are close to form a concentric circle which is approximately horizontal to the air inlet; the air suction ports are closer to the side wall of the main cabinet body than the steam suction port; and the air suction ports are communicated with an air inlet ofthe blower device through one or more first arc-shaped pipes. According to the positive pressure space switch cabinet, the contradiction between heat dissipation and moisture prevention can be reconciled, so that the heat dissipation and the moisture prevention are both efficiently realized in an energy-saving manner by using a simple and convenient method.

Description

technical field [0001] The invention relates to a positive pressure space switch cabinet and belongs to the field of electrical equipment. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs; the main function of the switch cabinet is to generate, transmit, distribute and In the process of power conversion, switch, control and protect electrical equipment. [0003] When the switchgear is running, because there are many heating components in the cabinet, the excessive temperature rise will cause the mechanical and electrical properties of the electrical appliances to decline, and finally lead to the failure of the high-voltage electrical appliances, and even cause serious accidents. In order to ensure the safe operation of high-voltage electrical appliances within the work...
