低压短路热稳定校验实施中的问题

摘要

阐述在低压短路电流热稳定校验过程中，将公式中的I理解为短路电流有效值，而不考虑断路器的保护作用的作法是有偏差的。%It is explained that discrepancy will be generated in the practice of interpreting ＂ I ＂ in the formula as effective value of short-circuit current without taking protective action of circuit breaker into consideration in the process of verification of thermal stability of low-voltage short-circuit current.
