Partial discharge(PD)in GIS can induce SF6 to decompose.Research on the quantitative measurement of PD energy and mode recognition is somewhat difficult currently.In order to analyze the gaseous decomposed components of SF6 under PD,a multi-functional experiment platform is devised.This paper mainly introduces its structure and corresponding parameters.Practical experiments indicate that PD can be induced and that the gaseous components such as SO2F2、SO2、CF4、Air and CO2 can be detected by the devised gaseous component analysis unit.The result of experiment is consistent with the IEC and GB standards basically.Furthermore,kinds of PD can be simulated;comprehensive information about PD,such as the gaseous decomposed components,response signal of gas sensor,ultraviolet photon microgram and the discharge current pulse signal,can be acquired by the detecting units.In all,based on the platform,comprehensive experimental methods are available for in-depth research on the relation between PD and gaseous decomposed components,quantitative measurement of PD energy and mode recognition.
