摘要
针对设计阶段导体热稳定校验的重要性,总结低压电缆采用断路器和熔断器保护时热稳定校验的几种方法,并就短路点的位置选取进行探讨并提出作者的看法。
In view of the importance of conductor thermal stability verification in the design stage,several methods for thermal stability verification of low-voltage cables using circuit breakers and fuses for protection are summarized,the location selection of short-circuit points is discussed,and the author's views are put forward.
