Description of drawings
Fig. 1 is the structural representation of the utility model one specific embodiment.
The specific embodiment
Be described further below with reference to the technique effect of accompanying drawing, to understand the purpose of this utility model, feature and effect fully design of the present utility model, concrete structure and generation.
As shown in Figure 1, the utility model provides a kind of reducing temperature of cable tunnel device, is used to be equipped with the cable tunnel 2 of cable 1.This heat sink comprises ventilation system 3 and the control system 4 that is arranged in the cable tunnel 2 at least.
The hardware facility of above-mentioned various modules is prior art, and this paper repeats no more.
Wherein, data acquisition module 41 comprises a plurality of thermo detectors 411 (only illustrating 2 among the figure).A plurality of thermo detectors 411 are arranged on the inside of cable tunnel 2 at least, to obtain the internal temperature measured data of cable tunnel 2.
Setting data in measured data that data comparing module 42 collects data acquisition module 41 and the control system 4 compares, and obtains a comparison result.Instruction output module 43 sends different instructions according to different comparison results, to adjust the operational mode of each blower fan 31.
In concrete the use, when for example 45 ℃ of above-mentioned measured datas, for example 35 ℃ the time, instruction output module 43 sends enabled instruction greater than the setting data of control system, blower fan 31 is started working, by the temperature in the relatively low air reduction cable tunnel 2 of temperature outside the importing tunnel.
After work a period of time, above-mentioned measured data is reduced to when being lower than 35 ℃, and instruction output module 43 sends halt instruction, and blower fan 31 quits work.
The above-mentioned operational mode of blower fan 31 is divided into regular start-up mode, irregular start-up mode again in the utility model.
Particularly, regular startup is the mode that circulates repeatedly with certain operational mode such as to start or started one day every one day or started one day every two days or started two days every one day every day to start.Irregular startup refers to random startup at random, and the temperature difference reaches setting value between ground environment temperature and the cable tunnel temperature in case be preferably, and starts ventilation system automatically.
Start ventilation system in which way, the inside and outside temperature difference of the air draft ability, cable tunnel of electric power transfer amount, blower fan need taken all factors into consideration, the combined factors such as temperature of cable tunnel safe operation are determined.
