Description

technical field [0001] The invention belongs to the technical field of power electronics, and in particular relates to an online monitoring chip for transformer winding deformation. Background technique [0002] As the core equipment of the power system, the safe operation of the transformer plays a very important role in ensuring the safety of the power grid. Due to the transformer design, process manufacturing and operating environment, the transformer winding may be loosely deformed, especially after the transformer is subjected to overvoltage, the winding will have irrecoverable deformation. When the deformation is severe, it will affect the local electric field distribution and accelerate the local grease Aging of insulation until breakdown occurs. [0003] For this reason, the State Grid Corporation listed it as one of the technical problems to be solved in the 12th Five-Year Plan; it is stipulated in Article 15.2 of the No. 589 Document "Twenty-five Key Requirements ...
