摘要
Abstract
Fracture and corrosion of the main transformer metal accessories affect the safe operation of power grids. The four main typical faults of main transformer metal accessories were analyzed, ie. rotating rod hoop of load tap changers corrosion cracking, casing covers corrosion, casing clamp cracking, bellows deformation exceeding limit. Based on the above analysis, suggestion of strengthening the metal supervision in materials, infrastructure and transport inspection stage have been proposed to avoid major accidents of the main transformer caused by metal accessories rusty breakage problems.关键词
