摘　　要：为提升特高压换流站二次安全措施的标准化作业流程,提高工作效率,降低失误率,开发了基于图像识别的二次安全措施布置工具。设计了带自锁功能可测电流的便携式试验线,通过在接线过程中实时显示电流和接触压力避免端子虚接,利用自锁功能解决接线误碰脱落;开发了基于图像识别的复原校核装置,实现端子连片及保护压板复原自动校核。该工具在某换流站进行了应用试验,结果表明,压板首次复原失误率为3.56%,软件复原效验检出率可达100%,提升了特高压换流站供电的可靠性。In order to improve the standardized operation process of the secondary safety measures of the UHV converter station,improve the work efficiency and reduce the error rate,a secondary safety measures arrangement tool based on image recognition was developed.A portable test line with self-locking function to measure current is designed,which avoids terminal virtual connection by displaying the current and contact pressure in real time during the wiring process,and solves wiring accidentally touching and falling off by using the self-locking function.Then,a restoration verification device based on image recognition has been developed to realize the automatic verification of the recovery of terminal pieces and protective pressure plates.The application test of the tool was carried out in a converter station,and the results showed that the error rate of the first recovery of the pressure plate was about 3.56%,and the detection rate of the software recovery effect could reach 100%,which improved the reliability of the power supply of the UHV converter station.
