Case Analysis of Reactor Heating Failure

Reactors are important equipment in substations, and their safety is related to the safety of the entire substation, which in turn affects the safety of the power grid. In this paper, a case of 10kV reactor thermal failure caused by a 110kV substation was burned down, and the specific process of the accident was explained in detail. Through a series of tests such as high-voltage electrical test and infrared temperature measurement, the cause of the reactor heating was analyzed. Propose relevant and technical measures to prevent the recurrence of such accidents.
