摘要
对应于变压器各级别额定容量,针对电缆不同类型、截面和长度,以及不同短路电流持续时间,探讨低压电缆热稳定校验,并给出若干热稳定校验实用速查表。
Corresponding to rated capacity at all levels of transformers and for different types,sections and length of cables,and different duration of short-circuit current,this paper discusses the check of thermal stability of low-voltage cables and provides some useful lookup tables of thermal stability.
