摘要
Ice-melting with short-circuit in transmission line is the most effective methods of de-icing. Conductor would be damaged if rapidly rising conductor temperature exceeds the allowable temperature. A lot of laboratory experiments were carried out on both LGJ-240/30 and LGJ-400/35 conductor in the artificial climate chamber. The tests results and analysis show that the maximum temperature of conductor is determined by two factors including the thickness of ice and ice-melting current, and is not influenced by ambient temperature and wind velocity. Also a method to calculate the maximum temperature of conductor is put forward.
