大型商厦低压配电系统评估及N线电流异常分析

Evaluation of Low-voltage Distribution System for Large Commercial Buildings and Analysis of N-line Current Abnormality

针对已投入使用的大型商厦低压配电系统N线电流异常情况进行的低压配电系统评估工作进行总结。通过预先进行的理论分析目标,结合检测过程中发现的问题分析产生异常的原因,对其影响范围、危害程度等进行评估,并给出解决问题的方法和建议方案。

Summarized voltage distribution system is the evaluation of low- conducted for the N-line current abnormality identified in a large commercial building. Based on the objective of theoretical analysis conducted in advance, in combination with the problems found during inspection, the causes for the abnormality are analyzed, its scope of influence and extent of hazard are evaluated and the corresponding solutions and recommended plans are given.
