However, when the cooling oil temperature is too high, the cooling oil inside the oil tank will spray to the outlet, thereby affecting the operation of the transformer. At the same time, the sealing ring at the outlet will age under the condition of long-term wind and sun exposure, which will cause oil leakage. Summary of the invention

When it rains, rainwater enters the interior of the groove and flows to the outside of the oil tank through the guide groove, thereby preventing the rainwater from causing corrosion damage to the first sealing ring and the second sealing ring. When it is necessary to detect the quality of the cooling oil, the cooling oil inside the oil tank will enter the interior of the collecting barrel through the through hole. When the detection rod is taken out, the quality of the cooling oil can be checked inside the collecting barrel to consider whether it needs to be replaced. BRIEF DESCRIPTION OF THE DRAWINGS
