Embodiment 1
[0031] Figure 1 to Figure 4 It schematically shows that a forced guiding cooling three-phase oil-immersed distribution transformer is provided according to the first embodiment of the present invention.
[0032] Such as figure 1 As shown, the present invention discloses a forced-guided cooling three-phase oil-immersed distribution transformer, which includes an oil tank 1, and a transformer core is installed in the oil tank 1. At the same time, the oil tank 1 is filled with high-temperature resistant insulating oil. In this embodiment of the invention Among them, the high-temperature-resistant insulating oil is β liquid, and silicone oil FR3 natural ester can also be used in practical applications. The transformer core is immersed in high temperature resistant insulating oil.
[0033] Such as Figure 1 to Figure 4 As shown, preferably, in this embodiment of the present invention, the oil tank 1 adopts a corrugated oil tank, such as image 3 As shown, the oil tank 1 is a h...
Embodiment 2
[0042] Figure 1 to Figure 6 It schematically shows that a forced guiding cooling three-phase oil-immersed distribution transformer is provided according to the second embodiment of the present invention.
[0043] Such as Figure 1 to Figure 4 As shown, the second embodiment of the present invention discloses a forced-guided cooling three-phase oil-immersed distribution transformer which is basically the same as Embodiment 1, except that:
[0044] Such as figure 2 , image 3 , Figure 5 and Figure 6 As shown, as another invention point of the present invention, in this embodiment of the present invention, a control system for controlling the fuel tank in the fuel tank 1 is included, the control system includes a liquid level sensor 28 fixed on the inner wall of the fuel tank 1, and A controller 27 above the cover 2, and the liquid level sensor 28 is connected with the controller 27. Such as figure 2 As shown, the liquid level sensor 28 is fixed on the upper end of on...
