Abstract

The invention discloses a switch cabinet capable of automatically cooling and dehumidifying, and belongs to the field of switch cabinets. The switch cabinet comprises a cabinet body provided with an exhaust tube at the top, a cooling device and a dehumidifying device, wherein the dehumidifying device comprises a gas suction pump, a moisture tube, a dry gas tube and a drying tank, the both ends of the drying tank are detachably connected with the moisture tube and the dry gas tube, the other end of each of the moisture tube and the dry gas tube stretches in the cabinet body, and the moisture tube is connected with the gas suction pump; the cooling device comprises a dry ice production device, a dry ice storage box and a circulation tube, the dry ice production device is communicated with the dry ice storage box through a middle tube, the dry ice storage box is communicated with the dry ice production device through the circulation tube, a temperature sensor, a humidity sensor, a smoke sensor and a gas pressure detector are arranged in the cabinet body, and a controller is arranged at the outer side of the cabinet body. According to the switch cabinet disclosed by the invention, a circulation cooling system is formed by virtue of dry ice gasification, the heat dissipation efficiency is high, and moreover, the dehumidifying device is simple in structure and free from generating additional heat during working.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to an automatic cooling and dehumidification switch cabinet. Background technique [0002] The switchgear is a commonly used electrical equipment, which mainly plays the role of opening and closing, controlling the transmission line, and protecting the electrical equipment. The long-term high temperature and high humidity inside the switchgear will cause electrical aging, electrical insulation strength reduction, and metal corrosion. Acceleration and other problems will cause explosion or fire in serious cases. However, most of the switch cabinets in the prior art dissipate heat through air circulation, and the heat dissipation effect is poor. In addition, the switch cabinets in the prior art are generally provided with heating devices in the cabinet. The heating of the device can play a certain role in dehumidification, but the heat generated by the heating device is dissipated into ...
