摘要

本文研究了非正弦稳态运行条件下低压电缆的热尺寸问题。特别考虑了四导体低压电缆馈送组单相非线性负载的情况，如台式电脑、电视、调光器等。特别注意显示中性导体结构对电缆容量的影响。本文给出并讨论了低压配电系统中电缆的数值应用，以说明谐波对电缆容量的影响。

On four-conductors low voltage cables ampacity in balanced and unbalanced nonsinusoidal conditions

In this paper the problem of the low voltage cables thermal sizing in nonsinusoidal steady-state operating conditions is considered. In particular, the case of four conductors low voltage cables feeding groups of single-phase nonlinear loads such as desktop computers, TV, light-dimmers and so on is taken into account. Particular attention is paid to show the influence of the neutral conductor configuration on the cable ampacity. Numerical applications referred to cables of low voltage distribution systems are presented and discussed in order to show the influence of the harmonics on the cable ampacity.
