【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。
[Abstract]:The role of electric power cable in power transmission and distribution system is very important. It often causes the temperature rise due to various faults, which causes the cable overheating or insulation aging. Therefore, it is necessary to monitor the temperature of the cable. The monitoring method of the temperature of the power cable is summarized and summarized, which are summarized in two categories according to the monitoring and remote monitoring. Methods, contact type electrical signal temperature measurement, infrared temperature measurement, temperature sensing cable temperature measurement, optical fiber temperature measurement and wireless temperature measurement are used to analyze their advantages and disadvantages, and their applications are introduced.
