Application of Portable Tower Arc Sag Observer in Transmission Line Engineering
摘要
The arc sag is the key point of quality control in the erection of transmission lines, and the accuracy of its observation directly affects the operation safety of the line. The research status of arc sag observation of transmission lines is introduced, the theoretical and practical basis and structural and functional parameters of the arc sag observer on the convenient tower are analyzed, and the good results obtained by the arc sag observation of Anhui Shuangling-Transformer-Anqing 3500 kV transmission line project are introduced, which provides reference for similar projects.
