Abstract
The utility model discloses an anti-condensation structure for a power distribution station house and an outdoor ring network cabinet. The anti-condensation structure comprises a cable well and a metal cabinet body arranged on the cable well. The anti-condensation structure is characterized in that a moistureproof separator plate through which cables penetrate is arranged between the cable well and the cabinet body. Since the moistureproof separator plate is arranged between the cable well and the metal cabinet body, vapour in the well is prevented from going into the cabinet body, the condensation can be well prevented from forming, and corrosion of the cabinet body as well as damage of cable heads and in-cabinet devices are prevented. The anti-condensation structure is simple in structure, good in strength, and easy to perform construction; no power-cutting operation on the devices and lines is needed during installation; and device failure due to small animals going into the cabinet can also be prevented.
Description
Technical field
The utility model belongs to controller switching equipment, is specifically related to the anti-dewfall structure of a kind of distribution station and outdoor ring main unit.
Background technology
Condensation is when air humidity reaches certain degree of saturation, a kind of phenomenon of condensing on the relatively low object of temperature.Distribution station and outdoor ring main unit are often because ambient humidity problem causes cabinet condensation serious at present, cause cabinet corrosion to cause cabinet gas leakage, base plate sedimentation and the cable end interval humidity fault etc. that is short-circuited more greatly, cause equipment not reach that life cycle just need to be changed and the electric discharge of ring main unit cable interval is made short circuit and caused cable end and looped network cabinet equipment damage.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, anti-condensation effective distribution station and the anti-dewfall structure of outdoor ring main unit.
The technical scheme that realizes the employing of the utility model object is as follows:
The distribution station that the utility model provides and the anti-dewfall structure of outdoor ring main unit, comprise cable shaft, be located at the metal cabinet on cable shaft, is provided with the moistureproof dividing plate that cable passes between described cable shaft and cabinet.
Described moistureproof dividing plate comprises silicate plate body, and the surrounding of plate body is provided with stainless steel stent, plate body be below provided with successively fiberglass enhancement layer and damp-proof layer, plate body is provided with cable aperture; Described plate body is fixed on described cable shaft by support; Space between the cable aperture of plate body and cable and between plate body and cable shaft takes gasket coating and fire guard to seal.
Distribution station and outdoor ring main unit are all located at outdoor, for the more southern area of rainwater, in the time of most in cable shaft, all there is certain ponding, and because well temperature is high compared with room temperature, cause steam more, in the ordinary course of things, steam moves upward, a part is discharged by ring main unit basis ventilating opening, a part enters ring main unit by some holes of ring main unit base, can image cable shaft is likened into steamer, ring main unit just can be regarded steaming tray as, this process is called " the steamer effect " of ring main unit.Because the cabinet of distribution station and outdoor ring main unit is metal cabinet, it dispels the heat fast compared with soil at normal temperatures, when the steam at the local end enters ring main unit, day temperature is higher, and steam is many, and having arrived temperature sank at night will be at the inner condensation that forms of cabinet.The utility model is owing to being provided with moistureproof dividing plate between cable shaft and metal cabinet, block steam in well and entered cabinet, can prevent preferably the formation of condensation, avoid device damage in casing corrosion, cable end and cabinet, it is simple in structure, and intensity is good, is easy to construction, during installation, do not need the operation that has a power failure of equipment, circuit, can also prevent from that toy from entering in cabinet, to cause equipment fault.
Below in conjunction with accompanying drawing, further illustrate the technical solution of the utility model.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the moistureproof dividing plate schematic diagram in the utility model.
Embodiment
See Fig. 1, Fig. 2, the distribution station that the utility model provides and the anti-dewfall structure of outdoor ring main unit, comprise and be embedded in the cable shaft 1 of establishing ventilating opening 3 in a of ground, be located at the metal cabinet 2 on cable shaft 1, between described cable shaft 1 and cabinet 2, be provided with the moistureproof dividing plate 5 that cable 4 passes, moistureproof dividing plate 5 comprises silicate plate body 501, the surrounding of plate body 501 is provided with stainless steel stent 503, plate body 501 be provided with successively below fiberglass enhancement layer 502 and damp-proof layer 502 ', fiberglass enhancement layer 502 consists of epoxy resin and glass fabric, damp-proof layer 502 ' employing epoxy resin, dibutyl ester, acetone and silica flour modulation form, plate body 501 is provided with cable aperture 504, described plate body 501 is fixed on described cable shaft 1 by support 503, space between the cable aperture 504 of plate body 501 and cable 4 and between plate body 501 and cable shaft 1 takes gasket coating and fire guard to seal.
