Abstract
Tension clamp, as an important fitting on transmission line, plays a key role in connecting conductor and transmitting mechanical load. Since the power grid is in operation, the overheating phenomenon of tension clamp drainage board caused by poor connection quality of contact fittings has become increasingly prominent, and has become a serious accident threatening normal operation of transmission lines. In this paper temperature calculation model of drainage board was established, and the temperature was calculated, and influence of wind speed, ambient temperature, current and type on drainage board temperature was studied. The results show that drainage board temperature decreases as wind speed raises, and drainage board temperature increases as ambient temperature and current increase. Drainage board temperature of different types of tension clamp is different. The drainage board with larger size usually has lower temperature.
