Given the frequent adhesion of vertically arranged double-split conductors， the research on adhesion is of practical significance. The fault of 220 kV lines is taken as an example to establish an adhesion model of the double-split model based on the conductor state equation and electromagnetic force calculation to study the impact of wire temperature， wind speed， DC resistance error， tension， and other factors on conductor adhesion. The study shows that the critical current of the conductor adhesion increases as the conductor temperature rises and decreases with the increase of the tension， sub-conductor resistance error， and wind speed. Under the interaction of resistance and wind speed， the critical current reaches its minimum in the case of the maximum resistance error value and the minimum wind speed. The research results can provide a useful reference for line design and modification. |
