Semi-conductor high-voltage cabinet dehumidification device

Abstract

The invention discloses a semi-conductor high-voltage cabinet dehumidification device, and belongs to power supply guaranteeing equipment of the power industry. The appearance of the semi-conductor high-voltage cabinet dehumidification device is a piece-shaped body formed by splicing semiconductor cooling pieces; a heating face of the semi-conductor high-voltage cabinet dehumidification device is attached to a metal shell inner wall of a high-voltage power distribution cabinet through thermally-conductive silicone, and a cooling face of the dehumidification device is tightly attached to a metal thin film; the outer surface of the metal thin film is a polished plane; inclined flow collecting strips are arranged on the plane; and the flow collecting strips are led to the outer side of the high-voltage power distribution cabinet through a backflow water pipe. The semi-conductor high-voltage cabinet dehumidification device has the advantages that the device is attached to the metal shell inner wall inside the high-voltage power distribution cabinet, and the temperature difference generated by the semiconductor cooling pieces is utilized for collecting and flowing water drops agglutinated on the cooling face together; and the water drops are drained through a pipeline, and therefore the interior of the high-voltage cabinet is kept dry. The semi-conductor high-voltage cabinet dehumidification device is particularly suitable for being used under the humid environment in rainy seasons in summer or in the southern area. The device does not additionally occupy the space, and is particularly suitable for being used for small-type high-voltage power distribution cabinets. No mechanical wear exists, and the dehumidification device is free of maintenance, and can work for a long time; and the working environment of power equipment components is greatly improved.

Description

technical field [0001] The invention belongs to power supply guarantee equipment in the electric power industry, and relates to a dehumidification device for a high-voltage cabinet. Background technique [0002] A large number of high-voltage distribution cabinets are used in the power supply system of the power industry, many of which are in outdoor natural environments. These high-voltage power distribution cabinets are inevitably attacked by wind and rain, especially in hot and humid summer, when the humidity in the air is particularly high, the safety of power supply will be affected to a certain extent. Therefore, some large high-voltage power distribution cabinets are equipped with dehumidifiers, but many small high-voltage power distribution cabinets are limited by the internal space and cannot use dehumidification equipment, which will adversely affect the power supply operation.
