In the power system, the transformer, as a core device, is crucial for safe and stable operation. Transformer cooling oil not only plays a vital role in cooling the transformer windings and core but also has important functions such as insulation and arc - extinguishing. However, with the long - term operation of the transformer, the cooling oil will inevitably become contaminated. Impurities such as water, solid particles, and dissolved gases can mix in, seriously affecting the performance of the cooling oil and threatening the normal operation of the transformer.
