Abstract

The invention provides ventilation and moisture removal equipment for a cable trench of a transformer substation. The equipment comprises a cable trench cover plate with an air vent, an explosion-proof axial flow fan arranged on the air vent and a ventilation pipeline. The cable trench cover plate comprises a connecting plate and four isosceles trapezoid-shaped side plates, wherein an air vent is formed on the top of the connecting plate; and the four isosceles trapezoid-shaped side plates are arranged on the edge of the connecting plate respectively, and are slightly inclined downwards. The axial flow fan is provided with a sealing cover. An opening is formed at the bottom of the sealing cover, and is opposite to the air vent. An air exhaust hole is formed on the sidewall of the sealing cover. The ventilation pipeline is arranged on the air exhaust hole. The ventilation and moisture removal equipment for the cable trench of the transformer substation has the advantages of scientific design, high practicability and good moisture removal effects, and is easy to use.

Description

technical field [0001] The invention relates to a dehumidification device for cable trenches, in particular to a dehumidification device for cable communication wind in a substation. Background technique [0002] At present, there is a lack of dynamic monitoring for cable trenches in most substations and cable interlayers in the lower part of switch cabinets. Due to moisture and other reasons, it is easy to cause corrosion of electrical equipment and protective devices, reduce the insulation strength of equipment, and cause flashover of equipment in substations, etc. Accidents seriously affect the safety of power supply and the healthy operation of equipment. With the development of the information technology era, intelligent substations have been vigorously promoted, and intelligent monitoring of high-voltage electrical equipment has developed rapidly. In order to solve the above existing problems, people have been seeking an ideal technical solution. [0003] In order to...
