[0002] Partial discharge of transformers is one of the main causes of insulation degradation of power equipment. Each discharge, the impact of high-energy electrons or accelerated electrons, especially long-term partial discharge, will cause various forms of physical effects and chemical reactions. For example, when charged particles hit the outer wall of the bubble, it may break the chemical bonds of the medium, destroy the molecular structure of the medium, cause insulation degradation, and accelerate the insulation destruction process. In severe cases, it may cause equipment failure and even affect the normal operation of the power grid. Therefore, as one of the important equipment in the power system, it is necessary to monitor the transformer.

[0003] In the prior art, many solutions have been proposed for the above problems. However, some of the existing solutions are too heavy or too large to be carried, and some can only detect a limited area after being fixed once. If you want to expand the detection range, you need to manually move the entire device from time to time, which will cause the entire detection process to be discontinuous, and there is a high possibility of repeated detection or missed detection.
