摘　　要：电力电缆在电力输配电系统中的作用至关重要,常会由于各种故障造成温度升高,从而导致电缆过热或绝缘老化,因此,对电缆温度的监测十分必要。归纳总结了电力电缆温度的监测方法,按就地监测和远程监测两大类综述了示温腊片法、接触式电信号测温法、红外测温法、感温电缆测温法、光纤测温法、无线测温法等方法,分析各自优缺点,并介绍了其应用情况。The power cables play an important role in power transmission and distribution system. Thecable temperature would increase because of different faults, which would lead to overheating or insulationageing of cable. Therefore, it is very necessary to monitor the cable temperature. The cable temperaturemonitoring methods were summarized. The temperature monitoring methods were divided into localmonitoring method and remote monitoring method, then the local monitoring method, including wax labelmethod, contact electrical signals thermometry, infrared thermometry, and the remote monitoring method,including temperature sensing cable thermometry, optical fiber thermometry, wireless thermometry, werereviewed. Their advantages, disadvantages, and application were analyzed respectively.
