Abstract
The utility model relates to a transformer substation part, and provides a novel special moisture-expelling terminal box for a transformer substation. The novel special moisture-expelling terminal box comprises a box body and a box cover which is fixedly connected with the box body. A heating device is disposed in the box body. An upper part of the box cover is in the shape of a roof ridge, while a lower part is a cuboid. The lower part of the box cover is provided with multiple moisture-discharging holes. Compared with a conventional terminal box, the upper part of the box cover is in the shape of the roof ridge, and the lower part is a cuboid, a side or the bottom of the lower part of the box cover is vertically provided with a row of moisture-discharging holes, and a filter net is disposed at a position of an inner side of the box cover, the positioning corresponding to the moisture-discharging holes. With moisture-discharging holes in the upper part, moisture gas cannot go through the lower part and enter the box, and because of the effect of a silica gel heater, the upper part of the box body is in a positive pressure state, and thus the moisture air cannot go into the box body. Furthermore, the roof-ridge-shaped box cover is helpful in water discharging in raining days, and helps to reduce shocks by rainwater to the terminal box.
Description
Technical field
The utility model relates to that a kind of transformer station parts, particularly a kind of Novel transformer substation are special drives damp terminal box.
Background technology
Terminal box is distribution field common device, in the occasion extensive use such as power plant, transformer station.Terminal box is arranged on open air mostly, and work under bad environment, particularly in southern area, there was dampness in the air, when switch terminal chamber door, wet gas is entered after terminal box and can cause that in terminal box, humidity is too high, be terminal box inevitable function in the time of design so drive damp function.
Fig. 2 is the existing terminal box that drives damp function that has, in terminal box, there is silica gel heating plate, in the time that interior humidity is too high, heating plate starts, and air is upwards flowed, top presents malleation, bottom presents negative pressure, and extraneous air enters terminal box by the aperture of terminal box bottom, and inner air expands under the effect of silica gel heating plate, density reduces to upper stream moving, is flowed out by the aperture at terminal box top.Because all perforates, cause steam to discharge from top up and down, introduce from bottom again, do not reach and drive damp effect, and silica gel plate, for a long time in heated condition, wastes energy, also fragile; Further, the respectively perforate in casing both sides, when windscreen wiper wind, rainwater can prolong casing and go deep into perforate, and then enters casing, causes line short in terminal box, has potential safety hazard instantly.
Summary of the invention
Problem to be solved in the utility model is to provide that a kind of safe and reliable Novel transformer substation is special drives damp terminal box, to meet the job requirement of the intelligent electronic device in terminal box.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: Novel transformer substation is special drives damp terminal box, comprises casing and the case lid affixed with described casing, in described casing, is provided with heater; The first half of described case lid is ridge, and Lower Half is cuboid, and this case lid Lower Half is provided with multiple moisture discharging openings.Adopt the case lid of ridge with being beneficial to rainy day draining, reduce the impact of rainwater to terminal box.
Further, the position corresponding with moisture discharging opening, described case lid inner side is provided with screen pack.
What further, the side of described case lid the latter half or bottom surface were vertical opens several rows of damp hole.
Further, the back door place of described heater setting and casing, this heater is silica gel heating device.
Advantage and the good effect that the utlity model has are: the more original terminal box of terminal box of the present utility model, the first half of case lid is ridge, Lower Half is cuboid, what the side of this case lid the latter half or bottom surface were vertical opens several rows of damp hole, and the position corresponding with moisture discharging opening, case lid inner side is provided with screen pack.Only offer moisture discharging opening on top, wet gas can not enter in case by bottom, and due to the effect of silica gel heating device, makes casing top present barotropic state, and humid air can not enter in case.And adopt the case lid of ridge with being beneficial to rainy day draining, reduce the impact of rainwater to terminal box.

Embodiment
With specific embodiment, the technical solution of the utility model is elaborated by reference to the accompanying drawings.
As shown in Fig. 1 or 4, Novel transformer substation is special drives damp terminal box, comprises casing and the case lid 1 affixed with described casing, in described casing, is provided with heater; The first half of described case lid 1 is ridge, and Lower Half is cuboid, and this case lid Lower Half is provided with multiple moisture discharging openings 2.The position corresponding with moisture discharging opening 2, described case lid 1 inner side is provided with screen pack.What the side of described case lid 1 the latter half or bottom surface were vertical opens several rows of damp hole.4 places, back door of described heater setting and casing, this heater is silica gel heating device.
As shown in Figure 3, switch terminal case Qianmen 3 is overhauled wet gas is entered after terminal box, can cause that in terminal box, humidity is too high, silica gel heating device starts, gas temperature in terminal box is raise, volumetric expansion, the moisture discharging opening 2 of steam from case lid 1 discharged outside case, reduce air humidity in case, make humidity recover normal level.Because only have top perforate, so wet gas can not enter in case by bottom, and due to the effect of silica gel heating device, make casing top present barotropic state, humid air can not enter in case.Meanwhile, because top perforate in side or the bottom surface of case lid the latter half, has prevented that rainwater from entering in case by moisture discharging opening 2.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variation and improvement etc. of doing according to the utility model scope, within all should still belonging to this patent covering scope.
