Embodiment

[0032] The present invention at least includes an aluminum alloy cable trough box body with a fireproof partition, an integrated aluminum alloy cover plate with a ventilation hole, an aluminum alloy installation cross arm with a longitudinal drainage hole, a fireproof partition board that doubles as a structural stress rib, etc. .

[0033] Firstly, the cable trough box body 1 is designed. According to the laying and safety protection requirements of power engineering cables and optical cables, three fire compartments are designed: power cable area 15, control cable or optical cable first area 16, and control cable or optical cable second area 17. In order to meet the requirements of the on-site personnel to step on the force, the fireproof partition 4 is designed to double as the structural stress rib. The structural stress rib and the tank box body 1 are designed in one piece, and are formed at one time by extruding aluminum alloy profiles, or using plate Connect with the tan...

Abstract

The invention discloses a shallow embedded ground electric cable tray system. The shallow embedded ground electric cable tray system comprises a tray body, wherein the cross section of the tray body is divided into at least two functional areas by a fire-proof clapboard; a plurality of vents are formed in a bottom plate of the tray body and outer side plates of the functional areas; a tray cover is arranged on the upper face of the tray body; the two sides of the tray cover are connected with side face baffle plates used for baffling broken stones and being close to the outer side plates of the tray body; fire-resistant binding strips used for fixing an optical cable or an electric cable are arranged in the functional areas; the tray body is separated into three functional areas through fire-resistant clapboards, including a power electric cable area, a first control electric cable or optical cable area and a second control electric cable or optical cable area; a mounting cross arm used for fixing the tray body and separating the tray body from a ground concrete base or a cushion layer is arranged at the lower bottom of the tray body; the lower ends of the side face baffle plates on the two sides of the tray cover are supported on the mounting cross arm; and at least two rows of waist-shaped vents are punched in the two sides of the upper surface of the tray cover. An electric cable tray is applied to outdoors to replace the traditional electric cable ditch, so the civil engineering amount is greatly saved, and the engineering construction period is shortened. Therefore, the shallow embedded ground electric cable tray system is very suitable for electric power engineering occasions, such as a digital converting station and an intelligent converting station.

Description

technical field [0001] The invention relates to a shallow-buried ground cable trough system, especially a shallow-buried ground cable trough system based on a fire-proof partition design, which is suitable for laying cables and optical cables in power plants, substations, especially smart substations. Fire separation. 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 requires a large amount of work, a long construction period, and difficult project management and quality control. [0003] In recent years, the advancement of technology has led to the development of electric power engineering in the direction of digitalization and intelligence. Especially for smart substations, through the use of advanced digital communication, automatic control, intelligent analysis and other technologies, while ...
