摘　　要：结合工程案例,分析了住宅区小容量负荷供电距离。指出在尽量减少变配电所数量的基础上,充分利用断路器的短路短延时整定值可调的有利条件,尽量延伸小容量负荷低压供电距离,并满足电压降、短路灵敏度的校验。An example of project, this paper analyzed the supply power distance of small capacity load in residential district. Based on minimizing the quantity of substation and distribution station, the short-circuit and short- time delay setting values of of hreaker was used fully to extend the low voltage supply power distance of small capacity load. It meets the validation of voltage drop and of short-circuit sensitivity.

关 键 词：变配电所 供电距离 电压降 电压偏差 短路灵敏度
