基于单片机的电力电缆绝缘故障在线监测系统的设计与构建

电力电缆在运行过程中,必然要出现绝缘老化,甚至引发绝缘击穿,导致供电线路的突发停电事故。绝缘老化的本质是材料性能发生不可逆转的改变,影响老化的因素一般涉及热、电、机械与环境等方面。在线监测通过全系统多测点数据联合分析计算电缆绝缘状况,综合确定漏电或绝缘降低的情况和故障点位置,因而具有重要价值。文章为此主要介绍基于C8051单片机的电力电缆在线监测系统的组成、监测功能和监测原理。

Design and Construction of Power Cable Insulation Fault-line Monitoring System Based on Single Chip

As we all knowed that the power cable are bound to insulation aging during operation and even lead to insulation breakdown,lead to the sudden power outage power lines.The insulation aging is the essence of irreversible changes in material properties that affected the general aging of the factors involved the thermal,electrical,mechanical and environmental aspects.The on-line monitoring uses the data calculation methods for analyzing the calculation cable insulation condition,and determing the positions of leakage,so it had great value.It is introduced that components,monitoring function and monitoring principles of the C8051 MCU-based power line monitoring system.
