Description
Technical field
The utility model belongs to cable maintenance field, specifically, particularly relates to a kind of cable trough and drives damp ventilation unit.
Background technology
Cable duct of substation in design, for preventing toy from entering damage electric power facility, adopts sealing design always.Cable trough locates below ground level, its humidity is comparatively large, and cable trough natural draft is poor, and moisture cannot be exchanged by inner air and outer air and moisture is evaporated away, cause cable trough humidity high, the support corrosion of cable trough inside is serious, and especially at thunderstorm season, cable insulation level reduces, cable running environment is severe, in cable trough, steam is heated rising, and easily cause device mistaking signal, influential system normally runs.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of cable trough to drive damp ventilation unit, and its structure is simple, and easy to use, production cost is lower, and ventilation effect is better, and can effectively prevent toy from entering damage electric power facility in cable trough.
Described cable trough drives damp ventilation unit, comprises cable channel cover plate, and described cable channel cover plate is provided with more than one ventilation unit, and described ventilation unit comprises straight length and bend loss, and straight length is fixedly connected with bend loss; Described bend loss is provided with protecting wire net.
Further, described cable channel cover plate both sides are respectively equipped with ventilation unit, and the ventilation unit direction of cable channel cover plate both sides is contrary.
Further, the air outlet angle a of described bend loss is 30 °-60 °.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model structure is simple, rationally distributed, easy to use, production cost is lower, and ventilation effect is good, greatly reduces the humidity in cable trough, effectively prevent the problem of cable trough internal stent corrosion, improve cable running environment, reduce the number of times of mistaking signal, improve power supply reliability;
2, by the protecting wire net on bend loss, effectively can prevent toy from entering in cable trough and damage electric power facility.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
In figure, 1, ventilation unit; 2, cable channel cover plate; 3, straight length; 4, bend loss; 5, protecting wire net.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, cable trough drives damp ventilation unit and comprises cable channel cover plate 2, and described cable channel cover plate 2 is provided with more than one ventilation unit 1, and described ventilation unit 1 comprises straight length 3 and bend loss 4, and straight length 3 is fixedly connected with bend loss 4; Described bend loss 4 is provided with protecting wire net 5; Described cable channel cover plate 2 both sides are respectively equipped with ventilation unit 1, and ventilation unit 1 direction of cable channel cover plate 2 both sides is contrary; The air outlet angle a of described bend loss 4 is 30 °-60 °.
In utility model when making, arrange quantity and the height of ventilation unit 1 according to the length of cable trough, the mesh specification of protecting wire net 5 is 5*5mm; Air outlet angle a the best of bend loss 4 is 45 °; During use, cable channel cover plate 2 is covered on cable trough, and under natural wind action, cable trough is ventilated, by detecting the humidity in test cable ditch, the medial humidity in cable trough is down to 58% by original 75%, and the number of times of device mistaking signal also greatly reduces on year-on-year basis.
