Improved fireproof cable trench applied to transformer substation

Abstract

The invention provides an improved fireproof cable trench applied to a transformer substation, and belongs to the technical field of electric power facilities. The improved fireproof cable trench comprises a cable trench, a plurality of supports arranged on the two side walls of the cable trench, a cover plate arranged on the top of the cable trench and a fire detector arranged in the cable trench, a prefabricated hole channel is formed in the cover plate, the prefabricated hole channel extends from the first side face of the cover plate to the bottom face of the cover plate, a connecting pipe is arranged in the prefabricated hole channel, the first end of the connecting pipe is connected with a fire extinguishing agent conveying pipe, the second end of the connecting pipe faces the interior of a cable trench and is connected with a nozzle, the fire extinguishing agent conveying pipe is connected with a fire extinguishing agent storage tank, the fire extinguishing agent storage tank is connected with a starter, the fire detector is connected with the starter, the starter is connected with the fire extinguishing controller, and the fire extinguishing agent is INERGEN. The invention provides the improved fireproof cable trench applied to a transformer substation so as to improve the fireproof performance of the cable trench.

Description

technical field [0001] The invention belongs to the technical field of electric power facilities, and in particular relates to an improved fireproof cable trench applied to a substation. Background technique [0002] Cable trench is an underground pipeline for laying cables. It is generally composed of trenches, cover plates and supports, and has types such as underground cable trenches, cable tunnels and cable direct burial. The operating environment of the cable trench is relatively single and relatively isolated from the outside world, which is conducive to the normal operation of the cable system. However, the passage in the cable tunnel is too long, there are bends, etc., resulting in insufficient ventilation, and there are conditions such as cable aging and local temperature rise. There is a fire hazard in the power cable. [0003] Since various types of cables are arranged in the cable trench, the fire will spread further through the cable trench, which will easily c...

AI Technical Summary

Problems solved by technology

This technical solution needs to install parts such as coil springs and fan blades in the cable trench, which will affect the inspection work of the cable trench. Moreover, in case of danger, the upper rotating cover plate is not easy to disassemble, which will affect the timely rescue of the fire.
