工业项目中长距离低压配电线路的设计探讨

Discussion of long-distance low voltage distribution circuits design in industrial projects

配电线路的长度直接影响到线路电压降以及该线路上的短路电流大小,工业项目中基于其工艺特点,经常会遇到低压配电线路长度过长,导致线路电压降偏高或断路器保护灵敏性不足的情况。本文结合工程经验,通过分析与计算,探讨长距离配电的解决方案。

The length of distribution circuit directly affects the voltage drop and the short-circuit current on the circuit.Based on the process characteristics of industrial projects,it is often occurred that the length of low voltage distribution circuit is too long,resulting in high voltage drop or insufficient sensitivity of circuit breaker protection.Combined with practical project experience,through analysis and calculation,discusses the solution of long-distance distribution.
