A kind of heat dissipating device of transformer, including trapezoidal fuel tank, be arranged trapezoidal fuel tank side oil inlet valve and fuel-displaced valve with
And the chimney in trapezoidal fuel tank is set up and down；
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 and is connected to bottom
Two straight panels of the another both sides of plate and the top plate being 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 the bottom of trapezoidal fuel tank is exposed in the lower end trepanning of the chimney
Plate.
As a further improvement on the present invention, the same straight panel in trapezoidal fuel tank is arranged in the oil inlet valve and fuel-displaced valve
On, 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.
As a further improvement on the present invention, the quantity at least two of the oil inlet valve, the number of the fuel-displaced valve
Amount at least two.
As a further improvement on the present invention, the chimney is variable diameter passage, and lower end opening diameter is opened more than the upper end
Bore dia.
As a further improvement on the present invention, the quantity of the chimney is four or more.
Compared with prior art, obtained by the present invention to have the beneficial effect that：
Traditional multiple flaky radiators are repacked into a large-scale trapezoidal shape radiator by the present invention, are full of in trapezoidal fuel tank exhausted
Edge oil, and installs multiple small-sized chimneys in trapezoidal fuel tank, and trapezoidal fuel tank is exposed in the trepanning of chimney both ends respectively, using thermal convection current,
Heat is transmitted, stack effect realizes air free convection in chimney, takes away ladder type fuel tank interior insulation oil heat indirectly, not only structure
Rationally, it safeguards simply, and improves transformer heat dissipation effect, reduce the workload of installation and the maintenance of radiator.
Description of the drawings
Accompanying drawing 1 is the structural representation of the present invention；
Attached drawing 2 is the schematic cross-sectional view of the present invention.
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 present invention 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 present invention is not required to any ancillary equipment, and realizes efficient, energy saving.Effectively subtract
Lack flaky radiator quantity, reduces the overall weight and volume of transformer.
Traditional multiple flaky radiators are repacked into a large-scale trapezoidal shape radiator by the present invention, are filled in trapezoidal fuel tank
Full 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, right using heat
Stream, 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, and improves transformer heat dissipation effect, reduces the workload of installation and the maintenance of radiator.It improves
Transformation sink-efficiency has extensive application value.
Embodiment described above is merely a preferred embodiment of the present invention, and the simultaneously exhaustion of the feasible implementation of non-present invention.It is right
For persons skilled in the art, any aobvious to made by it under the premise of without departing substantially from the principle of the invention and spirit and
The change being clear to should be all contemplated as falling within the claims of the present invention.
