10.5 kV电缆绝缘降低分析与故障诊断

10.5 kV Cable Insulation Reduction Analysis and Fault Diagnosis

随着电力行业的发展,电缆越来越多地运用到生产生活的各个领域,然而电缆都埋入地下或进入电缆沟敷设,当电缆发生故障后,选择运用何种形式的技术方法针对发生在电缆线路技术组件之上的故障事件展开全面及时检测和快速定位,控制和降低电缆线路技术组件运行故障修复过程中的经济成本支出,控制减少因停电事件发生而引致发生的各类损失,是现阶段我国电力工程行业领域的技术工作人员应当广泛关注和研究的问题.在电力电缆线路技术组件的具体运行使用过程中,通常会不可避免地发生类型多样的技术故障,且不同类型的技术故障在查找定位难度方面存在显著差异,在一定程度上给电缆线路技术故障测距分析,以及空间定位工作的具体组织实施过程造成了较大难度和不良影响.本文结合现场实际,详细介绍了电缆沟敷设10.5 kV电缆故障后的快速、准确、方便地判断和查找故障的方法,以供参考和借鉴.

With the development of the power industry,cables are increasingly used in all areas of production and life,and are buried underground or into cable trenches.When a cable fails,what form of technical method is used to target it.The technical fault events on the cable line technology components are fully and timely detected and quickly located,control and reduce the economic cost of the cable line technology component operation failure repair process,and control to reduce various losses caused by power outage events.It is a problem that should be widely concerned and studied by technical workers in the field of power engineering industry in China at this stage.In the specific operation and use of power cable line technology components,it is inevitable that various types of technical faults will occur inevitably,and different types of technical faults have significant differences in the difficulty of finding and positioning,and to some extent,cable line technology.Fault location analysis,as well as the specific organizational implementation process of spatial positioning work,have caused great difficulty and adverse effects.This paper combines the actual situation of the site,and introduces the method of judging and finding faults quickly,accurately and conveniently after the cable trench is laid with 10.5 kV cable for reference and reference.
