[0030] Refer to Figure 1, which shows a structural schematic diagram of a maintenance platform 100 of a transformer oil pillow 210 in an embodiment of the present application. Refer to Figure 2, which shows a front view of the maintenance platform 100 of the transformer oil pillow 210 in an embodiment of the present application. The maintenance platform 100 provided in an embodiment of the present application is arranged at the transformer oil pillow 210 and is used for personnel to inspect the oil pillow.

[0031] The transformer 200 includes a transformer oil pillow 210, a transformer body (not shown in the figure), and at least two oil pillow fixing brackets 220. The transformer oil pillow 210 is an oil storage device for the transformer 200. Its function is that when the transformer body increases due to the increase of load, the oil temperature increases, and the oil in the oil tank expands, then the excessive oil will flow into the transformer oil pillow 210. On the contrary, when the temperature decreases, the oil in the oil pillow will flow into the oil tank again, which plays the role of automatically adjusting the oil level, that is, the oil pillow plays the role of storing and replenishing oil, and can ensure that the oil tank is full of oil. At the same time, due to the transformer oil pillow 210, the contact surface between the transformer 200 and the air is reduced, and the moisture, dust and oxidized oil stains absorbed from the air are deposited in the sedimentation device at the bottom of the oil pillow, thereby greatly slowing down the deterioration rate of the transformer oil. Therefore, the transformer oil pillow 210 is usually arranged above the transformer body box cover, and the distance from the ground is high. The transformer oil pillow 210 fixing bracket is used to support the oil pillow on the transformer body, further increasing the distance from the ground. Taking this into consideration, the maintenance platform 100 of the present application is arranged on the transformer oil pillow 210, and provides a sufficient movable platform under the premise of ensuring the safety of personnel, so as to facilitate the maintenance of the upper part of the transformer body and the oil pillow.
