[0028] Furthermore, the oil cooling assembly 3 is connected by a storage box 5, a semiconductor refrigeration sheet 6, a cooling tube 7, a circulating pump 8 and a conduction plate 9.

When the constant potential instrument body 1 is in operation, it can be cooled by the oil cooling assembly 3 to prevent the temperature of the constant potential instrument body 1 from being too high, thereby affecting the operation. Transformer oil is used as the heat dissipation medium and is used in outdoor places in high temperature tropical areas that are conducive to overall heat dissipation.
[0029] Among them, a heat sink is provided on the outside of the storage box 5 and extends to the bottom of the constant potential instrument body 1. The heat sink extends to the interior of the storage box 5 and is connected to the semiconductor refrigeration sheet 6. The interior of the storage box 5 is filled with transformer oil. The semiconductor refrigeration sheet 6 is started. The end of the semiconductor refrigeration sheet 6 close to the heat sink is the heating end, and the end away from the heat sink is located inside the storage box 5 as the cooling end. The transformer oil inside the storage box 5 can be cooled through the cooling end, so that the transformer oil can cool the constant potential instrument body 1 through the cooling tube 7.
[0030] Secondly, the output end of the circulating pump 8 is connected to the cooling pipe 7, and the input end of the circulating pump 8 extends to the interior of the storage box 5.

Start the circulating pump 8 to circulate the low-temperature transformer oil in the storage box 5 into the interior of the cooling pipe 7. When the constant potential instrument body 1 is operating, the generated temperature is introduced into the interior of the cooling pipe 7 through the conduction plate 9, and the low-temperature transformer oil is cooled by the low-temperature transformer oil, thereby enabling the constant potential instrument body 1 to be cooled.

When the constant potential instrument body 1 is operating, the generated temperature is introduced into the cooling tube 7 through the conduction plate 9, and the low-temperature transformer oil is used to cool it, so that the constant potential instrument body 1 can be cooled to prevent the temperature of the constant potential instrument body 1 from being too high, which will affect the operation and enable it to operate safely and effectively. The telescopic cylinder is started to drive the moving block 13 to move, so that the connecting rod 12 can move, and the rotating rod 11 can be driven to rotate, so that the closing block 10 can rotate, and the heat sink is closed. Compared with the existing constant potential instrument, the utility model can improve the overall practicality of the constant potential instrument through design.
