Ventilation control system for cable duct

Abstract

The invention discloses a ventilation control system for a cable duct, which comprises a cable duct, a ventilation module, an intermediate module, a cycle conversion module and a power control module,wherein the ventilation module comprises a ventilation box body, a first air inlet, an air outlet, a first air inlet fan, and an exhaust fan; and the ventilation module, the intermediate module and the cycle conversion module are respectively connected with the power control module. The design is novel, the structure is compact, the overall is convenient and efficient, the ventilation performanceof the cable duct is better, the control system more tends to automation and intelligence, the control is precise, cold and heat exchange convection can be realized, and the ventilation volume can also be controlled; and besides, wind power generation can be used to carry out cycle conversion on the air, the cost is greatly saved, reasonable resource utilization is realized, the power transmission efficiency of the cable is ensured, the whole stability is good, and the safety performance is high.

Description

technical field [0001] The invention relates to the field of electric power, more specifically, to a ventilation control system for cable trenches. Background technique [0002] The cable trench is an underground pipeline for laying and replacing electric power or telecommunication cable facilities, and it is also an enclosure structure for the cable facilities to be laid. There are rectangular, circular, arched and other pipeline structures. [0003] The layout of cable trenches in power plants and substations is related to field equipment and terrain conditions, but both indoor and outdoor cable trenches generally have the following characteristics: [0004] First, the cable trench is a trench with a cover. The cover must be uncovered when laying and maintaining cables, which is very cumbersome and inconvenient. It is also easy to accumulate stolen goods and water in the trench. However, due to the simple civil construction and low cost, Often used in substations and smal...

AI Technical Summary

Problems solved by technology

[0010] First, the existing cable trench ventilation system has a low degree of management control, low intelligence and automation, and poor adjustment and adaptability;

[0011] Second, the existing cable trench management system requires a large amount of air-conditioning resources for heat dissipation, but the exhaust volume is large, and the exhaust gas cannot be recycled, resulting in high cost;

[0012] Third, the power cable trench is backfilled with fine sand, which is not conducive to the inspection and maintenance of the operation department, and the heat dissipation of the cable is poor during operation;

[0013] Fourth, when the cable bracket is used in the power cable channel, the heat dissipation of the cable channel is poor. Due to the lack of air convection, the cable generates serious heat and reduces the operating life of the cable;

[0014] Fifth, limited to the problem of land occupation, the power cable trenches in the city cannot build ventilation pavilions and other buildings above the ground
