摘　　要：总结了现有出线电缆测温技术存在的不足,提出了基于载波通信技术的电缆测温方法,研究利用感应电缆零序电流为测温装置供电,证实了该方法具有容易实现、造价低廉且长期免维护等优点。This paper generalizes the deficiencies of current technology for outlet cable temperature measurement, and proposes the method based on carrier communication technology. The research on the power supply to temperature measurement device by using zero-sequence current of the induced cable proves that this proposed method is superior in easy implementation, low cost, and long-term freedom of maintenance.
