Abstract
电力电缆在输配电线路中至关重要，经常会因各种故障导致电缆接头温度升高，从而导致电缆过热、绝缘老化等危害的发生。因此，对电缆接头温度监测十分重要。所以，本文从环网柜电缆接头运行的环境温度、电缆接头温升速率等方面，提出了一种电力电缆接头温度在线监测方法，可更准确的实现对电缆接头温度的实时在线监测及故障告警。 Power cable is critical to transmission and distribution lines, while due to all kinds of malfunctions, it often causes the rising temperature of the cable connector, leading to overheating of the cables, insulation aging and other hazards. Therefore, the temperature monitoring of cable connector is very important. So, from the Ring Main Unit cable joints operation of the environment temperature, the rate of cable connector’s temperature rise, etc., this paper proposes a online temperature monitoring method for the power cable connector, which can be more accurate for real-time online monitoring of the cable connector’s temperature and give fault alarm.
