不受环境鉴定要求约束的核电厂低压电缆老化管理

Aging Management of Low-Voltage Cable not Subject to Environmental Qualification

本文基于对电缆老化应力、局部恶劣环境识别、电缆状态监测技术以及国际核电厂电缆管理经验的研究和分析,给出核电厂不受环境鉴定要求约束的低压电缆的老化管理方法,可为国内运行核电厂非环境鉴定要求的低压电缆的老化管理提供支持和参考。

Based on the study and analysis on cable aging stress,adverse localized equipment environments identification,cable condition monitoring techniques,and international aging management experience of cable,a systematic aging management approach of low-voltage cable not subject to environmental qualification requirements is described.This paper can provide support and reference for domestic plant cable engineers when perform aging management of low-voltage cables not subject to environmental qualification requirements.
