Utility model content
The purpose of this utility model is to provide a kind of transformer cooling system that can carry out cooling system conversion when different electricity consumption amounts.
The technical solution of the utility model is:
Multi-mode transformer cooling system, be made up of oily circulating cooling system and air cooling system, oil circulating cooling system by oil pump, flowline, go out oil connecting pipe, radiating tube, inlet port, oil sucting cavity, oil-sucking hole and fuel tank main body and form, described fuel tank main body outer wall top is provided with oil pump; Described oil pump bottom is provided with the inlet port perpendicular to fuel tank main body top exterior walls; Described inlet port runs through fuel tank main body outer wall, is arranged with the oil sucting cavity that cross section is isosceles trapezoid in fuel tank main body in parallel, and inlet port is connected with one end vertical seal of oil sucting cavity; Isosceles trapezoid two waists of described oil sucting cavity cross section are symmetrically arranged with some oil-sucking holes on the whole; Described fuel tank main body arranged outside has the radiating tube in some faces, place of going to the bottom perpendicular to oil sucting cavity trapezoidal cross-section; Described radiating tube be " [" type hollow cavity, fuel tank main body inside is all stretched at the two ends of radiating tube, and remainder is outside at fuel tank main body; One end of described some radiating tubes is all connected to out in oil connecting pipe; Described oil pump is provided with flowline; Described flowline runs through fuel tank main body and is connected to out in oil connecting pipe; Described air cooling system is made up of fan and air-cooled pipeline, and described air-cooled pipeline is arranged on fuel tank main body outer wall, and radiating tube is positioned at the sealing of fuel tank main body Outboard Sections and is arranged at air-cooled pipeline cavity; Described air-cooled pipeline is provided with some fans; Described air-cooled pipeline outer wall is provided with the control board of control oil pump and fan swicth.The number of described some fans is 1.Described go out oil connecting pipe and can carry out many according to radiating tube position difference and parallelly to arrange.
The advantage that the utility model has and good effect are: owing to adopting technique scheme, in the high power consumption period, can open all cooling systems, realize forced oil-circulation air-cooled (OFAF); When power consumption is general, can oil pump be closed, utilize flow of hot and internal-external temperature difference to realize inner automatic oil and circulate, be equipped with air cooling system and realize oil (ONAF); When low electric power consumption amount, utilize flow of hot and internal-external temperature difference to realize inner automatic oil and circulate, realize oil (ONAN).

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, Figure 2, Figure 3 shows, multi-mode transformer cooling system, be made up of oily circulating cooling system and air cooling system, oil circulating cooling system by oil pump 1, flowline 2, go out oil connecting pipe 3, radiating tube 4, inlet port 5, oil sucting cavity 6, oil-sucking hole 7 and fuel tank main body 8 and form, described fuel tank main body 8 outer wall top is provided with oil pump 1; Described oil pump 1 bottom is provided with the inlet port 5 perpendicular to fuel tank main body 8 top exterior walls; Described inlet port 5 runs through fuel tank main body 8 outer wall, and in fuel tank main body 8, be arranged with the oil sucting cavity 5 that cross section is isosceles trapezoid in parallel, inlet port 5 is connected with one end vertical seal of oil sucting cavity 5; Isosceles trapezoid two waists of described oil sucting cavity 5 cross section are symmetrically arranged with some oil-sucking holes 7 on the whole; Described fuel tank main body 8 arranged outside has the radiating tube 4 in some faces, place of going to the bottom perpendicular to oil sucting cavity 6 trapezoidal cross-section; Described radiating tube 4 be " [" type hollow cavity, it is inner that fuel tank main body 8 is all stretched at the two ends of radiating tube 4, and remainder is outside at fuel tank main body 8; One end of described some radiating tubes 4 is all connected to out in oil connecting pipe 3; Described oil pump 1 is provided with flowline 2; Described flowline 2 runs through fuel tank main body 8 and is connected to out in oil connecting pipe 3; Described air cooling system is made up of fan 9 and air-cooled pipeline 10, and described air-cooled pipeline 10 is arranged on fuel tank main body 8 outer wall, and radiating tube 4 is positioned at the sealing of fuel tank main body 8 Outboard Sections and is arranged at air-cooled pipeline 10 cavity; Described air-cooled pipeline is provided with some fans 9; Described air-cooled pipeline outer wall is provided with the control board 11 of control oil pump and fan swicth.The number of some fans 9 is 1.Go out oil connecting pipe 2 and can carry out many parallel settings according to radiating tube 4 position difference.
