[0017] The traction transformer body has a vertical installation structure, in which the body 1 is placed vertically in the oil tank, the upper part of the body 1 is fixed to the upper part of the oil tank, and the clamp 3 at the bottom of the body 1 is placed on the bottom 2 of the oil tank. It is characterized in that: the body 1 is fixed to the bottom 2 of the oil tank by a fastener 4, the fastener 4 passes through the bottom 2 of the oil tank and is fastened to the body 1 by the clamp 3, and an inner sealing layer 5 is provided on the inner surface of the bottom 2 of the oil tank to internally seal the position where the fastener 4 passes through, and an outer sealing layer 6 is provided on the outside of the bottom of the oil tank to externally seal the position where the fastener 4 passes through.

[0018] In the vertical installation structure of the traction transformer body described above, the body 1 is placed vertically in the oil tank, and the body 1 is fixed to the oil tank bottom 2 by the fastener 1. The position of the body 1 in the oil tank is positioned, and an inner sealing layer 5 is provided on the inner surface of the oil tank bottom 2, and an outer sealing layer 6 is provided on the outer surface of the oil tank bottom 2. The position where the fastener 4 passes through the oil tank bottom 2 is sealed with an inner and outer double layer, thereby improving the sealing reliability of the oil tank bottom, effectively preventing oil leakage of the traction transformer, and improving the sealing reliability of the oil tank after the body is vertically installed.

[0019] The inner sealing layer 5 is positioned between the clamp 3 and the tank bottom 1, while the outer sealing layer 5 is positioned between the fastener 4 and the tank bottom 2. The inner sealing layer 5 is disposed inside the tank, while the outer sealing layer 5 is disposed outside the tank, providing a double seal around the fastener 4, preventing oil from leaking through the fastener.

[0020] The fuel tank bottom 2 has a mounting hole 21, the clamp 3 has a through hole 31, and the body 1 has a threaded blind hole 11. The mounting hole 21, through hole 31, and threaded blind hole 11 are coaxially aligned. The fastener 4 passes through the mounting hole 11 and through hole 31 and is threadedly locked in the threaded blind hole 11. The fastener 4 extends inward from the bottom of the fuel tank. The mounting hole 11 and through hole 31 guide the fastener's insertion position, allowing the fastener 4 to quickly enter the threaded blind hole 11 and engage with its threads.

[0021] The inner diameters of the mounting hole 21 and the through hole 31 are equal, and the inner diameter of the mounting hole is larger than the inner diameter of the threaded blind hole. The fastener 4 is clearance-fitted with the mounting hole 21 and the through hole 31, so that it can be easily inserted and aligned with the threaded blind hole 11 and screwed in for locking.
