This study develops and analyzes a simulation model for the breathing phenomenon in a 110 kV oil-immersed transformer, utilizing a thermal-fluid-structure interaction (TFSI) physical mechanism. This model provides key parameters such as breathing volume and maximum breathing rate, as well as their dynamic characteristics under different operating conditions, which can provide data support for breathing system fault identification, and also can provide a new feature quantity for the multidimensional monitoring of the trans-former.

摘要

This study develops and analyzes a simulation model for the breathing phenomenon in a 110 kV oil-immersed transformer, utilizing a thermal-fluid-structure interaction (TFSI) physical mechanism. This model provides key parameters such as breathing volume and maximum breathing rate, as well as their dynamic characteristics under different operating conditions, which can provide data support for breathing system fault identification, and also can provide a new feature quantity for the multidimensional monitoring of the trans-former.
