Abstract

The basin-type insulator is an important part of the gas insulated metal enclosed switchgear（GIS）. This paper will study the crack detection technology of the basin-type insulator. This paper mainly discusses the detection method of the cracking failure of the basin-type insulator

manufacture of radial run through crack with larger size for independent basin insulator

comparison of the vibration modes of the basin type insulator under the condition of intact and damaged condition

analysis of the variation of the natural frequency and frequency spectrum. Then pro-posed the method of fault diagnosis based on mechanical vibration technology. It provides an important basis for the further research and application of the vibration detection technology of basin-type insulator.
