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
