Drainage type intelligent dehumidification device

Abstract

The invention discloses a drainage type intelligent dehumidification device, which comprises a dehumidification box connected with the switch cabinet body, the dehumidification box is fixed at the bottom of the switch cabinet body, and a low-temperature air pipe connected to the side of the dehumidification box is provided, and the low-temperature air pipe passes through the air The barrel is docked with the return pipe, and the front end of the return pipe is fixed on the upper side of the switch cabinet body; the connection between the low-temperature air pipe and the return pipe is provided with an interception box, and a plugboard slidingly connected to it is inserted in the interception box, and the plugboard covers There is a dehumidification net, and a sealing ring is provided at the connection between the insert plate and the interception box; the dehumidification box is provided with a fixed partition, which is arranged in a horizontal direction and docked with the inner wall of the dehumidification box. There are connection holes on the fixed partition; when performing dehumidification work, through the setting of auxiliary air pipes, temperature sensors, two control valves and other structures, heat exchange and cooling are performed first, and then condensation and dehumidification are performed to ensure dehumidification. At the same time of thoroughness, the safety of equipment is also guaranteed through intelligent control.

Description

technical field [0001] The invention relates to auxiliary equipment of a switch cabinet, in particular to a drainage type intelligent dehumidification device. Background technique [0002] With the rapid development of the urban power grid, the distribution equipment is increasing year by year; during the operation of the equipment, when the air humidity is too high, the surface of the equipment will condense moisture, which will cause the mold to grow faster, reduce the electrical insulation strength, and the metal corrosion will lead to oxidation of the contact surface. The resistance increases; because the influence of humidity is a chronic process, it is generally not dealt with in time, and the maintenance is not organized until the equipment is completely out of operation, which increases the difficulty and intensity of maintenance, affects production and increases maintenance costs, and even May cause major safety accidents.

Problems solved by technology

[0002] With the rapid development of the urban power grid, the distribution equipment is increasing year by year; during the operation of the equipment, when the air humidity is too high, the surface of the equipment will condense moisture, which will cause the mold to grow faster, reduce the electrical insulation strength, and the metal corrosion will lead to oxidation of the contact surface. The resistance increases; because the influence of humidity is a chronic process, it is generally not treated in time, and maintenance is organized when the equipment is completely inoperable, which increases the difficulty and intensity of maintenance, affects production and increases maintenance costs, and even May cause major safety accidents

[0003] Chinese patent announcement number CN209929691U proposes a self-cooling drainage-free intelligent dehumidification device, CN207006405U proposes a drainage type dehumidification device, etc., all of which use condensation to condense and liquefy the moisture in the air to ensure the safety of electrical equipment such as switch cabinets. Normal operation, but the problem is that in order to further facilitate the operation of the equipment, the usual practice is to directly transport the condensed and dried air to the cabinet, but the direct convection of cold and hot air can easily cause liquid water in the cabinet, causing the equipment to The generation of rust and corrosion will cause damage to the equipment
