Abstract As for abnormal heat fault of the 110kV breaker Arc-extinguishing chamber porcelain bushing with excess circuit resistance values, the reason of such fault is analyzed and treated based on the show of the infrared thermal imaging detection spectra of the breaker, on the test of oil,circuit resistance, dynamic resistance as well as transform-up current, the correctness of the diagnosis result is verified through disassembly, which provides scientific reference to the fault diagnos, operation and maintenance of the breaker as well as suggestionson operation and maintenance of the breaker.
