Abstract
This paper proposes a method for establishing a power transformer fault tree based on fault cases. The method includes obtaining multiple fault cases of power transformers, dismantling multiple fault cases according to preset dismantling rules, classifying the faults of power transformers according to multiple fault cases, and establishing the basic framework of the fault tree. According to the results of dismantling, we are able to determine the logical relationship between the fault cause and the fault phenomenon of the power transformer. Based on the basic framework of the fault tree and the determined logical relationship, we build a fault tree for power transformers based on fault cases. This method will effectively improve the role of fault cases in the establishment of power transformer fault trees, realize fault identification and diagnosis of power transformers with high efficiency and high practicability, improve the efficiency of transformer fault analysis and disposal, and save power outage time caused by transformer faults.
