Description

Technical field [0001] The invention relates to the field of wire overfire performance testing, in particular to a transmission line overfire performance evaluation and detection platform. Background technique [0002] With the continuous development of my country's power industry, more transmission lines are laid. Transmission lines used for long-distance power transmission usually pass through forests and other areas. Transmission line failures caused by vegetation fires frequently occur, which has brought serious impacts and losses on people's production and life. Compared with other disasters such as strong winds and hail, the failure of transmission lines caused by fires will lead to longer outages, so it is particularly worthy of attention in power system safety research. Current researches on transmission line fires mostly focus on the impact of the disaster process. The focus on the parameters is mainly the fire parameters, but there are few studies on the performance of...
