Abstract
The utility model relates to an auxiliary heat-radiating device of a transformer, mainly comprising a fan and a bracket, wherein the fan is fixed at the upper part of the bracket, the upper part of the fan is provided with blinds with 25 degrees horizontally, a cooling water pipe is arranged on the lower part of the bracket, and nozzles are arranged at the lower part of the cooling water pipe. The auxiliary heat-radiating device of the transformer is arranged at the bottom of a radiating fin of the transformer, when the fan is started, the blind is opened through blowing of the fan, when the fan is switched off, the blind can be closed automatically, and the fan and the blind are arranged with 25 degrees horizontally, the structure can prevent rain water from falling on the fan in rainy days, so as to prolong the service life of the fan. The cooling water pipe at the lower part of the bracket and the ground form a 45-degree angle, and six nozzles with diameters of 0.2mm are arranged at each of two sides of the cooling water pipe, so that the cooling water can be sprinkled on the ground evenly to reduce the surrounding temperature; when the fan is started, the cooling air with low temperature at the bottom part can be blown upwards to the radiating fin to effectively control the temperature of the transformer.
Description
Technical field
The utility model relates to electric substation's main transformer cooling system, especially a kind of transformer auxiliary radiating device.
Background technology
Summer high temperature period in season, electric substation is oepration at full load usually, and the transformer caloric value is big; Though transformer self is provided with four cooling fans, because blower fan is that radiating effect is limited laterally to blowing; Cause the transformer body temperature often to rise to more than 80 ℃; Start the overtemperature alarm system, this situation has been dwindled the useful life of transformer greatly, and has increased the potential safety hazard of transformer.
The utility model content
The purpose of the utility model is for the deficiency that solves above-mentioned technology a kind of transformer auxiliary radiating device to be provided.
In order to achieve the above object, a kind of transformer auxiliary radiating device that the utility model designed, it mainly comprises blower fan, support; Described blower fan is fixed on support top; Blower fan top is provided with blind, and the support bottom is provided with cooling water pipe, and the cooling water pipe bottom is provided with nozzle.The transformer auxiliary radiating device of this structure, blower fan top is provided with blind, can prevent splashing into of rainwater on rainy day.
On rainy day, in order to make the better landing of the rainwater that is dropped on the blind, described blower fan top is level and is provided with blind for 25 °.
In order to reduce the surrounding enviroment temperature, described transformer auxiliary radiating device, cooling water pipe and ground are 45 ° to the both sides nozzle that respectively to open 6 diameters be 0.2mm.
The resulting transformer auxiliary radiating device of the utility model is installed in the radiating fin of transformer bottom; When starting blower fan, blind is blown afloat by blower fan to be opened, when blower fan cuts out; Blind is also closed automatically; And blower fan and blind are 25 ° of settings of level, and this structure can prevent that rainy day, rainwater fell on the blower fan, can prolong blower fan useful life.Cooling water pipe that is provided with in the support bottom and ground are 45 ° and respectively open 6 diameter 0.2mm nozzles as both sides; Cooling water is evenly trickled down on ground; Reduce its surrounding enviroment temperature; During fan starting, the cooling air that the bottom is relatively low upwards blows to fin, and the transformer temperature is effectively controlled.
