Abstract:
As the core part of the substation, the transformer has an important influence on the reliability of power supply and the stability of the system. In order to ensure its safe and reliable operation, a cooler is installed to reduce the temperature and dissipate heat. Therefore, the normal operation of the cooler has an important influence on the operation of the transformer. In this paper, the working principle and power switching of transformer cooler are analyzed through a power loss event of transformer coole
