摘　　要：通过监测电力电缆的运行状态,可以实时监测电缆的温度、绝缘状况等,并及时发现潜在故障风险,提前预警,避免电力系统的停电事故发生。因此文章提出了基于多传感器的电力电缆运行状态监测研究。首先,基于多传感器采集电力电缆数据,并保存收集到的数据。然后继续监测采集端口,采集下一次局部放电的数据。最后,设置了电缆转换运行电路,对每个分支数据进行分时收集和处理,以上述数据为基础对电力电缆局部放电状态进行检测。试验结果表明,使用文章方法监测到的放电电压与试验所设定的故障放电电压趋于一致,最大误差为0.7V,证明了文章方法的可行性。By monitoring the operation status of power cables,the temperature and insulation status of the cables can be monitored in real-time,and potential fault risks can be identified in a timely manner.Early warning can be given to avoid power outages in the power system.Therefore,the article proposes a research on power cable operation status monitoring based on multiple sensors.Firstly,collect power cable data based on multiple sensors and save the collected data.Then continue to monitor the collection port and collect data for the next partial discharge.Finally,a cable conversion operation circuit was set up to collect and process data from each branch at different times.Based on the above data,the partial discharge status of power cables was detected.The experimental results show that the discharge voltage monitored using the article method tends to be consistent with the fault discharge voltage set in the experiment,with a maximum error of 0.7V,proving the feasibility of the article method.
