摘 要: 本文针对高温超导电缆在电力系统中的过电流保护,从电缆本体温升的角度,研究了过电流情况下高温超导电缆本体温升的计算方法,以此为基础,讨论并提出了一种过电流保护方案。 In terms of overcurrent protection of HTSC in power system, this paper presents a method for calculating the temperature rise in the body of HTSC due to overcurrent. Based on this method, a new protection solution is presented, in which the differential protection of current and the overheating protection of the body of HTSC are combined.
