The invention discloses a fault diagnosis method, device and equipment for a fuel gas pipeline cathode protection system, and the method comprises the steps: building a Schema architecture, obtaining a pipeline entity name through a target entity recognition model, and filling the recognized pipeline entity name into a corresponding position in the Schema architecture according to the attribute of the pipeline entity name, thereby achieving the fault diagnosis of the fuel gas pipeline cathode protection system. According to the method, the entity-relation-entity triple graph structure is constructed, the fault knowledge graph is formed, and complete intelligent fault diagnosis is performed on the gas pipeline cathode protection system through the fault knowledge graph without manual intervention, so that the fault diagnosis precision and efficiency of the gas pipeline cathode protection system are improved, and the operation and maintenance difficulty is reduced. 本发明公开了一种燃气管道阴极保护系统的故障诊断方法、装置及设备，通过搭建Schema架构，并
