Causal Analysis and Countermeasure Proposal with Respect to a Case of Heating and Oil Leakage Fault of Mid-voltage-side Bushing Encountered by an Actual Main Transformer
Infrared diagnostic technology has found wide application in detecting abnormal heating positions in transform-ers,which may result from overload,poor electrical contact,insulation aging,or other faults.By timely detecting and lo-cating these heating faults,preventive maintenance measures can be taken to avoid further occurrence of potential failure. This work focused on the timely discover of a case of heating and oil leakage fault of the 35 kV-side bushing of an actual 110 kV main transformer by infrared diagnostic technology.It conducted diagnostic analysis on the fault cause from the di-mensions of detection data and heating mechanism to avoid the expansion of equipment fault.It also proposed correspond-ing operation and maintenance suggestions.
