Abstract

The power system is developing towards high voltage and large capacity. As a physical node of the energy transmission network, the metal tool is subject to complex electrical and mechanical loads. The resistance loss and additional hysteresis loss of its body have become the key bottlenecks affecting the transmission efficiency of the power grid. The eddy current thermal effect generated by traditional galvanized steel tools in alternating electromagnetic field environment leads to significant energy consumption accumulation, and the unstable contact resistance at the contiguous part aggravates the risk of non-uniform temperature rise of the conductor. The engineering application of new aluminum alloys and carbon fiber composites breaks the inherent electromagnetic characteristics of metal materials, and combines the research and development of surface treatment and structural lightweight technology to build an energy-saving technology matrix from material conductivity optimization to structural form redesign. This research system aims to solve the inherent bottleneck of energy consumption in the metal link in the transmission and distribution lines, and provides scientific basis for improving the economic indicators of electricity transmission and system reliability.
