    High-voltage pillar-type porcelain insulators are important components of power plants and substations, and are widely used in power grids. In recent years, various kinds of accidents caused by breakage of pillar insulators have occurred frequently during the operation of the power grid, posing a serious threat to the safe operation of the power grid. Aiming at the problem of the deterioration detection of porcelain strut insulators in transmission lines, this paper introduces the detection principle of vibro-acoustic method and the vibro-acoustic detection process of porcelain strut insulators. A set of vibro-acoustic-based porcelain strut insulator detection equipment is studied and designed, and its design principle is expounded. And hardware components, the effectiveness of the detection function is verified through the actual measurement analysis, which provides support for the follow-up research and promotion of this detection technology.
