基于IFAHP的运行电缆绝缘状态综合评估

Comprehensive Evaluation of Insulation Status of Running Cable Based on IFAHP

针对现有评估方法中的局限性,以运行电缆的环境温度、环境湿度、电缆局部放电量和接地线漏电流为评价因素,提出了一种基于IFAHP的运行电缆绝缘状态综合评估法。首先,结合模糊评价理论,建立了基于IFAHP的多因素电缆绝缘状态评估模型,实现了对运行电缆更加客观、合理、准确的绝缘评估;其次,设计了基于LabVIEW的运行电缆绝缘状态综合评估系统,便于实际工程的应用;最后,通过实例分析,验证了评估模型的有效性和实用性。

Focusing on the limitations in existing assessment methods,take the ambient temperature and humidity of the running cable,the partial cable discharge and the ground line leakage current as the evaluation factors,a comprehensive evaluation method for running cable insulation state was proposed based on IFAHP.Firstly,an IFAHP-based multi-factor cable insulation state evaluation model was established combined fuzzy evaluation theory,which achieves more objective,reasonable and accurate insulation evaluation of the running cable.Secondly,a comprehensive evaluation system for running cable insulation state was designed based on LabVIEW,which is convenient for practical engineering applications.Finally,the validity and practicability of the evaluation model in this paper were verified by an example analysis.
