摘要

接头是中压电缆配电网的关键部件,其绝缘老化速度受负载电流和敷设环境参数的影响尤为敏感。这对监测接头的负载电流和敷设环境参数(湿度、压力和温度)非常有用,从而筛选出可能严重加速接头绝缘老化速度的条件。本文说明了安装湿度、压力、电流和温度传感器的情况——这是e-distribuzione(意大利主要的DSO)和博洛尼亚大学的合作项目——以评估地下配电网中电缆接头绝缘的老化率。

Monitoring Cable current and Laying Environment Parameters for Assessing the Aging Rate of MV Cable Joint Insulation
Joints are critical components of MV cable distribution networks and the aging rate of their insulation is particularly sensitive to temperature due to loading current and laying environment parameters. This makes it very useful to monitor the load current and laying environment parameters (humidity, pressure and temperature) of joints, so as to single out conditions that might accelerate joint insulation aging rate critically. This paper illustrates the installation of humidity, pressure, current and temperature sensors - in a partnership between e-distribuzione (the main DSO in Italy) and the University of Bologna - to assess the aging rate of cable joint insulation in underground distribution networks.
