To achieve the goals above, the technical solution that the utility model is taken is as follows:
A kind of heat dissipating device of transformer, including trapezoidal fuel tank, oil inlet valve and delivery valve in trapezoidal fuel tank side are set Door and the chimney being arranged up and down in trapezoidal fuel tank;
The trapezoidal fuel tank includes bottom plate, is relatively fixed and is connected to two inclined plates of bottom plate both sides, is relatively fixed connection Two straight panels in the another both sides of bottom plate and the top plate that is fixedly connected at the top of inclined plate and straight panel;
The top plate of trapezoidal fuel tank is exposed in the upper end trepanning of the chimney, and trapezoidal fuel tank is exposed in the lower end trepanning of the chimney Bottom plate.
The oil inlet valve and fuel-displaced valve are arranged in the same of trapezoidal fuel tank as a further improvement of the utility model, In straight panel, the oil inlet valve is higher than fuel-displaced valve, and the oil inlet valve is connected with the top oil reservoir of oil tank of transformer, described Fuel-displaced valve is connected with the bottom oil layer of oil tank of transformer.
The quantity at least two of the oil inlet valve as a further improvement of the utility model, the fuel-displaced valve Quantity at least two.
The chimney is variable diameter passage as a further improvement of the utility model, and lower end opening diameter is greatly thereon Hold opening diameter.
The quantity of the chimney is four or more as a further improvement of the utility model,.
Compared with prior art, having the beneficial effect that acquired by the utility model:
Traditional multiple flaky radiators are repacked into a large-scale trapezoidal shape radiator, trapezoidal fuel tank by the utility model It is interior to be full of insulating oil, and multiple small-sized chimneys are installed in trapezoidal fuel tank, trapezoidal fuel tank is exposed in the trepanning of chimney both ends respectively, utilizes Thermal convection current, heat are transmitted, stack effect realizes air free convection in chimney, take away ladder type fuel tank interior insulation oil heat indirectly, Not only reasonable for structure, maintenance simply, but also improves transformer heat dissipation effect, reduces the workload of installation and the maintenance of radiator.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model;
Attached drawing 2 is the schematic cross-sectional view of the utility model.
In attached drawing:1 trapezoidal fuel tank, 1-1 bottom plates, 1-2 inclined plates, 1-3 straight panels, 1-4 top plates, 2 oil inlet valves, 3 fuel-displaced valves, 4 chimneys, 41 upper end trepannings, 42 lower end trepannings.
Specific implementation mode
Further details of narration is carried out to the utility model below in conjunction with attached drawing.
As shown in attached drawing 1-2, a kind of heat dissipating device of transformer, including trapezoidal fuel tank 1, be arranged in 1 side of trapezoidal fuel tank Oil inlet valve 2 and fuel-displaced valve 3 and the chimney 4 being arranged up and down in trapezoidal fuel tank 1;The trapezoidal fuel tank 1 includes bottom Plate 1-1, it is relatively fixed and is connected to two inclined plate 1-2 of the both sides bottom plate 1-1, is relatively fixed and is connected to the another both sides bottom plate 1-1 Two straight panel 1-3 and the top plate 1-4 that is fixedly connected at the top of inclined plate 1-2 and straight panel 1-3;The upper end trepanning of the chimney 4 41 expose the top plate 1-4 of trapezoidal fuel tank 1, and the bottom plate 1-1 of trapezoidal fuel tank 1 is exposed in the lower end trepanning 42 of the chimney 4.The oil inlet Valve 2 and fuel-displaced valve 3 are arranged on the same straight panel 1-3 of trapezoidal fuel tank 1, and the oil inlet valve 2 is higher than fuel-displaced valve 3, institute It states oil inlet valve 2 with the top oil reservoir of oil tank of transformer to be connected, the bottom oil layer phase of the fuel-displaced valve 3 and oil tank of transformer Connection.The quantity at least two of the oil inlet valve 2, the quantity at least two of the fuel-displaced valve 3.The chimney 4 is Variable diameter passage, 42 diameter of lower end trepanning are more than 41 diameter of the upper end trepanning.The quantity of the chimney 4 is four or more.
When transformer normal operation, on the top oil reservoir of oil tank of transformer is higher than its underpart reservoir temperature, and temperature is higher Portion's oil reservoir is entered by the oil inlet valve 2 of 1 side of trapezoidal fuel tank in trapezoidal fuel tank 1, using chimney principle, in trapezoidal fuel tank 1 Multiple small-sized chimneys 4 are installed, the oil inlet valve 2 is higher than fuel-displaced valve 3, i.e., oil temperature is higher than fuel-displaced valve 3 at oil inlet valve 5 It is high to locate oil temperature, heat transfer process causes portion temperature on chimney 4 to be higher than lower part, the principle risen using hot-air, from chimney 4 Upper end trepanning 41 constantly discharge hot gas, upper part temperature is higher, and air movement speed is faster, to make outside it is fresh cold Air is involved in from the lower end trepanning 42 of chimney 4, realizes the entire mistake that air-flow is quickly moved from 4 bottom of chimney automatically upwards automatically Journey, air and the insulating oil of flowing exchange heat, and have indirectly taken away the heat of insulating oil.Insulating oil after cooling exchange heat from delivery valve Door 3 flows back into the bottom oil layer of oil tank of transformer.The utility model is not required to any ancillary equipment, and realizes efficient, energy saving.Have Effect reduces flaky radiator quantity, reduces the overall weight and volume of transformer.
Traditional multiple flaky radiators are repacked into a large-scale trapezoidal shape radiator, trapezoidal fuel tank by the utility model It is interior to be full of insulating oil, and multiple small-sized chimneys are installed in trapezoidal fuel tank, trapezoidal fuel tank is exposed in the trepanning of chimney both ends respectively, utilizes Thermal convection current, heat are transmitted, stack effect realizes air free convection in chimney, take away ladder type fuel tank interior insulation oil heat indirectly, Not only reasonable for structure, maintenance simply, but also improves transformer heat dissipation effect, reduces the workload of installation and the maintenance of radiator. Transformation sink-efficiency is improved, there is extensive application value.
Embodiment described above is only the preferred embodiment of the utility model, and the not feasible implementation of the utility model It is exhaustive.For persons skilled in the art, it is made under the premise of without departing substantially from the utility model principle and spirit Any obvious change gone out, should all be contemplated as falling within the claims of the utility model.
