Abstract

The invention discloses a moisture-proof condensed water guiding device which comprises a casing with a built-in power supply, wherein a moisture sensor, a controller and a draught fan are arranged on one side in the casing; the air outlet of the draught fan and the exhaust outlet in the casing are communicated; air inlets are formed in the casing; a water manifold connector communicated with a water collecting case in the casing is arranged at the lower part of the casing; a heating sheet is arranged at middle-upper part in the casing; a semiconductor cooler corresponding to the exhaust inlet of the draught fan is arranged at the lower part in the casing; the moisture sensor, the controller, the draught fan, the heating sheet and the semiconductor cooler are connected with the power supply through conducting wires respectively; the power supply is connected with an external power supply through a conducting wire plug; the semiconductor cooler is positioned at the upper part of the water collecting case. The moisture-proof condensed water guiding device has the advantages that the structure is simple, the assembly is convenient and the technical problems in the prior art that the moisture-proof and moisture removal operation are time-consuming and toilsome, the components in a cabinet are easy to be corroded and aged and the safety is unguaranteed are solved.

Description

[0001] technical field [0002] The invention belongs to the technical field of moisture-proof condensation induction for electric control cabinets, and relates to a moisture-proof condensation induction device, which can perform moisture-proof and dehumidification for electric-controlled closed appliances, especially moisture-proof and dehumidification in electric cabinets. Background technique [0003] There are a large number of electrical control cabinets in the power system, such as high and low voltage control cabinets, high and low voltage switch cabinets, ring network cabinets, outdoor terminal boxes, box-type substations, dry-type substations, etc. Due to the large number of components and the compact space in the cabinet, condensation is prone to occur in the control cabinet in a humid environment. Condensation inside the equipment will cause creepage and flashover accidents, which generally occur in the following situations: First, the humidity in the area is h...
