Abstract
The utility model provides a power transformation box, the power distribution box comprises a box body. The box top surface is equipped with dripping eaves in the syncline below all around, the dripping eaves below is equipped with humidity transducer, be equipped with at least one ventilation window that transversely sets up longitudinal arrangement on the box lateral wall, the border hinges on the ventilation window has the casement, every the border passes through the tightrope and links to each other under the casement of ventilation window, be equipped with the cylinder on the box roof, the piston rod of cylinder with the tightrope upper end links to each other. Under the normal condition, the piston rod does not stretch out, and the casement hangs on the piston rod of cylinder through the tightrope for the casement is parallel basically with ground, and the ventilation window is opened completely and is ventilated, humidity transducer monitors air humidity when reaching the setting value when rainy day, and the piston rod of cylinder stretches out, and the casement hangs down under the action of gravity, closes the ventilation window, keeps off the rain. The utility model discloses power transformation box the temperature high fine can ventilation cooling, convenient and practical can be kept off the rain to the rainy day that the temperature is low.
Description
Technical field
This utility model relates to a kind of power system auxiliary equipment, particularly relates to a kind of power transformation box.
Background technology
Power transformation box (substation) is exactly the casing in power system to the place that the voltage and current of electric energy converts, concentrates and distributes. For ensureing the safety of the quality of electric energy and equipment, in power transformation box, also need to carry out Voltage Cortrol, trend (in power system the flow direction of the voltage in each node and branch road, electric current and power and distribution) controls and the protection of electric line and main electrical equipment.
Power transformation box can guard box in-vivo device do not exposed to the sun and rain, it is also possible to isolation Keep Clear-High Voltage equipment also makes corresponding warning, causes danger in order to avoid non-working person touches by mistake. , the heat radiation of case in-vivo device especially transformator can be caused serious adverse effect, conventional power transformation box weak heat-dissipating by the existence of power transformation box, increases electric energy loss, also will reduce service life of equipment.
Summary of the invention
This utility model provides a kind of power transformation box for solving the technical problem that.
Technical solution adopted in the utility model is: a kind of power transformation box, including casing; Described box top surrounding is oliquely downward provided with dripping eaves; Described dripping eaves are connected with humidity sensor; Described wall box is provided with the vent window of at least string horizontally set longitudinal arrangement; Described vent window upper edge is hinged with sash; The sash lower edge of vent window described in each column is connected by tightrope; Described roof box is provided with cylinder; The piston rod of described cylinder is connected with described tightrope upper end. Under normal circumstances, piston rod does not stretch out, and sash is hung on the piston rod of cylinder by tightrope so that sash is substantially parallel with ground, and vent window fully opens and is aerated; When rainy day humidity sensor monitor air humidity reach setting value time, the piston rod of cylinder stretches out, and sash hangs down under gravity, close vent window, keep off the rain. This utility model power transformation box is in the high fine day energy ventilation and heat of temperature, and the rainy day that temperature is low is able to keep out the rain, convenient and practical.
In order to strengthen ventilation effect, as preferably, described casing left and right sidewall is equipped with vent window, and the vent window on the sidewall of left and right is relative.
In order to strengthen effect of keeping off the rain, described sash edge is provided with sealing strip, for gap between enclosed ventilation window and sash, stops that rainwater enters.
In order to further enhance effect of keeping off the rain, described vent window upper edge is provided with weather shield to obliquely downward outside described casing.
As further improvement, described box inside is connected with aqua storage tank at described vent window. Having a small amount of rainwater in life-time service casing unavoidably to enter, aqua storage tank is by a small amount of rain water-harvesting, in order to avoid equipment is had undesirable effect by rainwater stream to equipment place.
This utility model has the advantage that and has the benefit effect that owing to this utility model adopts as above technical scheme, under normal circumstances, piston rod does not stretch out, and sash is hung on the piston rod of cylinder by tightrope, making sash substantially parallel with ground, vent window fully opens and is aerated; When rainy day humidity sensor monitor air humidity reach setting value time, the piston rod of cylinder stretches out, and sash hangs down under gravity, close vent window, keep off the rain. This utility model power transformation box is in the high fine day energy ventilation and heat of temperature, and the rainy day that temperature is low is able to keep out the rain, convenient and practical.
Except the technical characteristic solving the technical problem that, constituting technical scheme except this utility model described above and the advantage brought by the technical characteristic of these technical schemes, the advantage that the other technologies feature comprised in other technologies problem that this utility model can solve, technical scheme and these technical characteristics bring, is described in further detail hereinafter in conjunction with accompanying drawing.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:
As depicted in figs. 1 and 2, the present embodiment is a kind of power transformation box, including casing 2; Described casing 2 end face surrounding is oliquely downward provided with dripping eaves 1; Described dripping eaves 1 are connected with humidity sensor 4; Described casing about 2 sidewall is provided with the vent window 5 of at least string horizontally set longitudinal arrangement relatively; Described vent window 5 upper edge is provided with weather shield 6 to obliquely downward outside described casing 2; Described vent window 5 box inside upper edge is hinged with sash 7; Described sash 7 edge is provided with sealing strip 8, for gap between enclosed ventilation window 5 and sash 7, stops that rainwater enters; Sash 7 lower edge of vent window 5 described in each column is connected by tightrope 9; Described casing 2 top board is provided with cylinder 3; The piston rod of described cylinder 3 is connected with described tightrope 9 upper end. It is connected with aqua storage tank 10 at described vent window 5 inside described casing 2. Having a small amount of rainwater in life-time service casing unavoidably to enter, aqua storage tank 10 is by a small amount of rain water-harvesting, in order to avoid equipment is had undesirable effect by rainwater stream to equipment place.
Operation principle of the present utility model is: under normal circumstances, piston rod does not stretch out, and sash is hung on the piston rod of cylinder by tightrope so that sash is substantially parallel with ground, and vent window fully opens and is aerated; When rainy day humidity sensor monitor air humidity reach setting value time, the piston rod of cylinder stretches out, and sash hangs down under gravity, close vent window, keep off the rain. This utility model power transformation box is in the high fine day energy ventilation and heat of temperature, and the rainy day that temperature is low is able to keep out the rain, convenient and practical.
Above embodiment of the present utility model is described in detail, but described content has been only preferred embodiment of the present utility model, it is impossible to be considered for limiting practical range of the present utility model.All equalizations made according to this utility model application range change and improvement etc., all should still belong within patent covering scope of the present utility model.
