The invention provides a dehumidification and ventilation type electrical power distribution cabinet which comprises a cabinet body, a semiconductor chilling plate, a fan, a partition plate and a waterproof and breathable film, the partition plate is fixedly installed in an inner cavity of the cabinet body and divides the inner cavity of the cabinet body into a first cavity and a second cavity, and the semiconductor chilling plate is fixedly installed on the partition plate. The hot end of the semiconductor chilling plate is located in the first cavity, the cold end of the semiconductor chilling plate is located in the second cavity, an air outlet and an air inlet are formed in the top and the bottom of the partition plate respectively, the draught fan is fixedly installed in the air outlet, and the peripheral edge of the waterproof breathable film is connected with the side wall of the air inlet in a sealed mode. A drain hole is formed in the bottom of the side wall, facing the partition, of the second chamber. According to the invention, the problem that the working performance of the electrical element is damaged and even the risk of short circuit occurs due to low-temperature condensation of the electrical element caused by moisture-proof and dehumidification operation of the existing power distribution cabinet through the semiconductor chilling plate can be overcome, and the normal work of the electrical element is ensured.
Description
technical field [0001] The invention relates to the technical field of electrical distribution cabinets, in particular to a dehumidifying and ventilating electrical distribution cabinet. Background technique [0002] The power distribution cabinet is a common electrical equipment, which is mainly used to install various circuit boards, switches and various instruments. Due to the different installation environments, moisture or condensation may occur inside the power distribution cabinet, which may easily cause accidents such as creepage and short circuit. In order to effectively prevent potential safety hazards such as equipment aging, short circuit, insulation strength reduction, secondary terminal breakdown, material mildew and corrosion of steel structural parts in the power distribution cabinet, and ensure the safe operation of the power grid, it is usually necessary to perform moisture-proof and dehumidification operations on the power distribution cabinet. .
