中文摘要：

GIS设备中局部放电（PD）的模式识别和放电量的定量检测是目前国内外研究的难点。为此,作者设计了一套用于SF6PD气体分解组分研究的多功能试验装置,重点介绍了装置的结构和主要部件的计算参数。初步试验研究表明：该装置能够产生PD并引起SF6分解,气体检测单元可有效检测SO2F2、SO2、CF4、空气、CO2等组分气体,检测结果与现有IEC和GB标准基本相符;能够在不同试验电压下,模拟各种PD,具有获取SF6气体分解组分、气敏传感器响应信号、微观放电图像、微观放电过程以及脉冲放电电流波形等多信息功能,从而为深入开展GISPD导致SF6分解组分的关联比对研究,最终为解决放电模式识别和放电量定量检测难题提供了综合试验研究手段。

英文摘要：

Partial discharge （PD） in GIS can induce SF6to 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 PI） can be induced and that the gaseous compo- nents such as SO2 F2 ,SO2 ,CF1 ,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.
