A shallow buried ground power cable trough box

Abstract

The invention discloses a shallow-buried ground electric cable trough box, which includes a box body and an installation cross arm, the installation cross arm is fixed at the bottom of the inner wall of the box, and the bottom of the installation cross arm is provided with a longitudinal drainage hole, so that A mounting plate is fixedly connected to the installation cross arm, and two first vertical plates and two second vertical plates are fixedly connected to the mounting plate, and the two second vertical plates are located between the two first vertical plates , the upper end of the box body is equipped with a box cover, the upper ends of the first vertical board and the second vertical board are all against the box cover, and two of the first vertical boards are equipped with cooling fans, and the two The second vertical plate is provided with a plurality of cooling holes. The invention has a reasonable structure, not only can effectively and efficiently dissipate heat in the box, reduce the impact on the cable, but also control the switch of the cooling fan according to the temperature, and can use the power reasonably. At the same time, the second dust-proof net can also be Self-cleaning, and cleaning effect is good.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a shallow-buried ground power cable trough box. Background technique [0002] For a long time, a large number of cables and optical cables in power plants and substations have been laid through cable trenches or cable tunnels. The construction of cable trenches or cable tunnels has a large amount of engineering, long construction period, and difficult project management and quality control. In recent years, technological progress has made electric power engineering develop in the direction of digitalization and intelligence, especially smart substations. Through the use of advanced digital communication, Automatic control, intelligent analysis and other technologies, while realizing intelligence, also make a very big difference in the laying of substation cables: the cables are greatly reduced and replaced by thin optical cables. This prompts us to look for other better ...

Problems solved by technology

[0004] The disadvantage of the above-mentioned published patent is that it has insufficient heat dissipation effect on the inside of the tank box, especially when the temperature is high in summer; secondly, it is provided with cooling holes to dissipate heat inside the tank box, but it has no dustproof effect. External dust easily enters the trough box, causing dust to fall on the cable and affecting the heat dissipation of the cable. Therefore, we designed a shallow buried ground power cable trough box to solve the above problems
