When the movable cover 12 moves upward, the temperature sensor 21 is driven to move upward through the mounting frame 20. When the movable cover 12 moves to the highest point, the electromagnet 803 is disconnected. At this time, the movable ring 701 and the plug block 603 can move downward and reset under the action of the third spring 703, so that the plug block 603 withdraws from the first slot 601. At this time, the first rotating shaft 402 is disconnected from the third rotating shaft 502, and the movable cover 12 can move and reset under the action of the second spring 302, so that the insulating oil temperature near the busbar joint body 101 can be monitored through the temperature sensor 21, and the monitoring is more comprehensive and the effect is better.

[0041] Moreover, when the movable cover 12 moves up and down, under the pushing action of the insulating oil, the movable plate 203 can be pushed to move along the guide rod 202. At the same time, the first spring 204 is deformed, thereby driving the brush 205 to automatically clean the head of the temperature sensor 21 to ensure the accuracy of its monitoring.
