Abstract
The utility model relates to a preassembled transformer station. The preassembled transformer station comprises a box body. A door is disposed on one side of the box body. A high voltage chamber, a transformer chamber, and a low voltage chamber are disposed in the box body. In the box body, the low voltage chamber is disposed at a side close to the door. The transformer chamber is arranged between the high voltage chamber and the low voltage chamber. A transformer is disposed in the transformer chamber. An exhaust vent is disposed on the top of the box body. An exhaust fan covering the exhaust vent is disposed on the top of the box body. A top cover covering the exhaust fan is also disposed on the top of the box body. A cone-shaped protective cover is also disposed between the exhaust fan and the top cover. The lower end of the protective cover is fixedly connected with the inner wall of the top cover. A sealing gasket is disposed between the connecting part of the protective cover and the connecting part of the top cover. An Air hole is disposed on the top of the protective cover. An air flow hole is disposed on the sidewall of the top cover. The heat of the preassembled transformer station can be timely dissipated.
Description
Technical field
The utility model relates to a kind of power supplying and distributing equipment that is applied to electric power system, is specifically related to a kind of preassembled transformer station.
Background technology
Existing substation equipment, because its structure existence designs, layout is unreasonable, ventilating system is perfect inadequately, can't effectively the heat in the transformer station be distributed.A kind of follow-on preassembled transformer station is arranged at present, and its structure is: comprise casing, described bottom half is provided with base plate, and described casing one side is provided with door; Described box house is provided with hyperbaric chamber, transformer room and low-pressure chamber, and described low-pressure chamber is located at a side of close door in the casing, and described transformer room is provided with between hyperbaric chamber and the low-pressure chamber, is provided with transformer and exhaust blower in the described transformer room.Though this preassembled transformer station inside is provided with exhaust blower, owing to there is not vent structure, air-flow can only be in the preassembled transformer station internal flow, can only discharge by the gap on the casing, very little because of the gap, cause the discharge efficiency of thermal current very low, still there is the problem of poor heat radiation.
Summary of the invention
At above-mentioned technical problem, the purpose of this utility model is to provide a kind of preassembled transformer station that can in time dispel the heat.
The technical scheme that realizes the utility model purpose is as follows:
Preassembled transformer station comprises casing, and described casing one side is provided with door; Described box house is provided with the hyperbaric chamber; transformer room and low-pressure chamber; described low-pressure chamber is located at a side of close door in the casing; described transformer room is located between hyperbaric chamber and the low-pressure chamber; be provided with transformer in the described transformer room; top at casing is provided with steam vent; the top of casing is provided with the exhaust blower that covers described steam vent; the top of casing also is provided with the top cover that covers described exhaust blower; between exhaust blower and top cover; also be provided with a profile and be pyramidal protective cover; fixedly connected with the inwall of top cover in the lower end of this protective cover; between the connecting portion of protective cover and top cover, be provided with sealing gasket; the top of protective cover is provided with air vent hole, and the sidewall of described top cover is provided with airflow hole.
Adopted such scheme, the steam vent of the utility model by being communicated with in cabinet body interior space, an exhaust blower is fixed in the upper end of cabinet body, this exhaust blower covers described steam vent, during use, forced ventilation effect by exhaust blower, gas in the casing is aspirated, make extraneous cooling air constantly enter into casing, these cooling air skim over from the surface of electric elements, take away the heat on the electric elements, discharge by air vent hole and airflow hole successively, thereby the heat on the electric elements is distributed in time, the temperature in the casing is remained within the rational working range.
The side wall surface of described top cover is provided with osculum, and this osculum is corresponding with the conical surface of protective cover.By the effect of protective cover, when rainwater enters into top cover when inner from airflow hole because the outer surface of protective cover is the conical surface, therefore, by the effect of protective cover outside wall surface, can make rainwater along the outer surface of protective cover to dirty, discharge by osculum then.
Further, the back of axially intersecting of the axial and top cover of described airflow hole is the acute angle of spending less than 90.The arrangement of steam vent can reduce rainwater as far as possible and enter into top cover inside.
Further, bottom half is provided with base plate, is provided with feet near four angles on the base plate.By base plate and feet, can prevent that bottom half from being corroded.
