摘　　要：设计了一种适用于GIS内部局部放电检测的新型SiPM传感系统,具有驱动电压低、体积小、光子转化率高等明显优势。通过局部放电光-电联合检测试验验证了新型SiPM传感系统与光电倍增管(PMT)及高频线圈(HFCT)对局部放电检测结果的一致性,也证明了局部放电相位分析法对SiPM检测结果分析的有效性。在此基础上对SiPM现场安装方式进行了研究和试验,结果表明SiPM传感系统在现场应用中也能取得优异的检测效果,能够为光测法的现场应用提供有效的技术支持。A novel SiPM sensor system suitable for internal PD detection in GIS was designed,which had obvious advantages such as low drive voltage,small volume and high photon conversion rate. The consistency of the new SiPM sensor system,photomultiplier tube(PMT)and high frequency current transformer(HFCT) of pulse current detection device for PD detection was verified through the PD light-electric joint test,and the validity of phase resolved partial discharge method on SiPM detection results was also proved. On this basis,the field installation mode of SiPM was studied and tested. The results showed that the SiPM sensor system could achieve excellent detection effect in the field application and provide technical support for the field application of optical measurement method.
