Dampproof and dehumidification switch cabinet

Abstract

The invention discloses a dampproof and dehumidification switch cabinet. The switch cabinet comprises a cabinet body and a cabinet door arranged on the cabinet body. A handle and an observation window are arranged on the cabinet door. A hollow separator plates is parallel arranged in the cabinet body. Multiple through holes are arranged in the separator plates which are connected with an air exhausting pipe. The other end of the air exhausting pipe stretches out of the cabinet body and then is connected with a gas exhausting device. A heating groove is arranged in the middle of the bottom of the cabinet body. A heating pipe is arranged in the heating groove. A temperature sensor is arranged at the bottom of the cabinet body. A humidity sensor is arranged on the separator plate. A PLC controller is arranged in the cabinet body and is connected with the temperature sensor and the humidity sensor via data lines. The PLC controller is electrically connected with the gas exhausting device and the heating pipe. The switch cabinet is simple in structure and convenient to manufacture; temperature and humidity in the cabinet body can be automatically controlled and displayed on a liquid crystal screen on the cabinet door; and the switch cabinet is brightly illuminated and a light can be easily opened.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a moisture-proof and dehumidification switch cabinet. Background technique [0002] The switchgear is an important part of the power system and an indispensable device in the process of power transmission and conversion. It can not only be used to protect various electrical equipment required in the process of power transmission, but also the sealed switchgear can avoid Others touch it by mistake, resulting in a safety accident. [0003] Although most of the switchgears are installed in open outdoor areas, some switchgears are also installed in areas with high humidity such as tunnels, basements, mines, and fields where it is difficult to get light. The air humidity in these areas is high and the temperature is low. The components in the cabinet are easily damaged if they work in this humid atmosphere for a long time, and the cables and wires may also be corroded, which is prone to safety acc...
