Four limiting shafts 15 are rotatably connected to the top of the oil tank 18. A limiting bolt 16 is arranged inside the limiting shaft 15. A limiting plate 17 is fixedly connected to the limiting shaft 15. A support column 19 is fixedly connected to the bottom of the oil tank 18. A base 20 is fixedly connected to the bottom of the support column 19. A grounding wire 21 is fixedly connected to the bottom of the shielding shell 1. A grounding groove 22 is provided at the bottom of the base 20. A grounding block 23 is slidably connected inside the grounding groove 22. A compression spring 24 is fixedly connected to the grounding block 23. The grounding block 23 is fixedly connected to the grounding wire 21. When installing a spare shielding plate, the shielding plate 6 to be replaced automatically pops out, which improves the convenience and safety of operation. This innovative design makes the maintenance and operation of the transformer more flexible.

[0021] An oil level gauge 25 is installed on the top of the oil tank 18 , and an oil thermometer 26 is installed on the top of the oil tank 18 . The oil level gauge 25 and the oil thermometer 26 can measure the oil amount and oil temperature inside the oil tank 18 .

[0022] The top of the oil tank 18 is provided with an oil outlet valve 27 , and the top of the oil tank 18 is provided with an oil inlet valve 28 . When the oil inlet valve 28 is opened, oil enters the oil tank 18 , and when the oil outlet valve 27 is opened, oil is sucked out of the oil tank 18 .

[0023] A heat conducting plate 29 is fixedly connected to the bottom of the oil tank 18, and two cooling fans 30 are installed on the top of the base 20. The cooling fans 30 can discharge the heat generated by the transformer during operation.

[0024] The outer chamber 3 is matched with the shielding plate 6, and the limiting bolt 16 is threadedly connected to the top of the oil tank 18. When the limiting bolt 16 is rotated, the bolt no longer squeezes the limiting shaft 15, so that it can rotate. When it is rotated to the specified position, the limiting bolt 16 is tightened to squeeze the limiting shaft 15 so that it cannot rotate.

[0025] The automatic pop-up mechanism 5 is provided with eight, the limiting hooks 11 are adapted to the guide grooves 8, the inner pressure plate 13 extends into the inner chamber 2, and when the shielding plate 6 is installed, the shielding plate 6 presses the outer pressure plate 12. Since this surface of the guide slope 10 is a right angle, the limiting hook 11 moves to the left until the small groove on the guide block 9 catches the limiting hook 11, and then the limiting plate 17 is rotated to complete the installation.

[0026] The working principle of a transformer oil tank shielding structure provided by the utility model is as follows:

[0027] When the shielding plate 6 needs to be maintained or replaced, the staff takes out the spare shielding plate and inserts it into the inner chamber 2. A long handle is connected to the top of the spare shielding plate. The inner chamber 2 is deeper than the outer chamber 3. When the spare shielding plate is inserted into the inner chamber, the bottom of the spare shielding plate presses the inner pressure plate 13, driving the sliding block 7 to move downward, and the limiting hook 11 slides inside the guide groove 8. The small protrusion inside the guide groove forces the limiting hook 11 to move to the right. After passing the guide slope 10, due to the influence of the tension spring 14, the limiting hook 11 enters the long groove inside the guide groove 8, and the restriction disappears. The tension spring 14 drives the shielding plate 6 to pop out of the outer chamber 3, and the spare shielding plate is still shielded in the inner chamber 2. After maintenance is completed, you only need to reinsert the shielding plate 6 and rotate the limiting plate 17. When the device is grounded as a whole, the grounding block 23 is pressed into the grounding groove 22, and the grounding of the shielding shell 1 is automatically completed.

[0028] Compared with the related art, the transformer oil tank shielding structure provided by the utility model has the following beneficial effects:

[0029] The device is provided with an automatic pop-up mechanism 5 which automatically pops out the shielding plate 6 that needs to be maintained and replaced when a spare shielding plate is placed, so that the device can more conveniently replace, disassemble and maintain the shielding plate, thereby reducing maintenance time and cost and improving the availability of the equipment. The spare shielding plate is used during maintenance to ensure continuous electromagnetic shielding of the transformer and avoid the impact of interruptions on other equipment. In addition, the grounding device of the shielding shell 1 does not require manual operation, reducing the risk of human error and improving the overall reliability of the system.
