| Abstract: | Internal insulation weakness,gas leaks,mechanical failure and other defects are existed in most of SF6 switchgear.Based on the operation condition and diagnostic technique,ultrasound PD,laser imaging and endoscopic detection have been studied.The application effect shows that above technique can effectively determine the operating condition make early treatment measures before the fault occurred,and greatly improve the reliability of equipment. |
