摘要

结合实际案例,阐述选择室外道路照明电缆截面积时,除考虑电缆载流量及线路电压损失外,还应考虑断路器的保护灵敏性,通过分析影响断路器保护灵敏性的因素,提出室外道路照明电缆截面积的选择建议.

Abstract

Based on practical cases,the paper elaborates that it is required to consider not only the current-carrying capacity and line voltage drop on cables but also the protective sensitivity of circuit breakers when the cross-sectional area is selected for outdoor road lighting cables.By analyzing the factors affecting the protection sensitivity of circuit breakers,it has proposed suggestions for selecting the cross-sectional areas of outdoor road lighting cables.
