[0002] A power transformer is a device used in power systems, mainly used for voltage step-up and step-down to ensure the effective transmission and distribution of electricity. Currently, power transformers need to undergo professional testing before leaving the factory. There are many aspects of testing, and the testing of power transformers is particularly important. Since power transformers are usually installed outdoors, in order to avoid erosion by water vapor or rain in the environment, the sealing performance of the power transformer needs to be guaranteed. When the sealing performance of the power transformer is tested, a comprehensive sealing test of the power transformer is required to avoid the situation where some areas of the power transformer are not detected. At the same time, water splashing is prone to occur during the sealing test of the power transformer. On the one hand, it affects the on-site technicians. On the other hand, water splashes into the test area and needs to be cleaned up later, which increases the workload of the personnel involved and reduces the effectiveness of the power transformer testing auxiliary station.

[0003] Therefore, it is necessary to develop a power transformer detection auxiliary platform. Utility Model Content
