摘要
介绍了电缆截面选择的几种方法,并结合工程实例,对核电厂BOP供电电缆截面选择时需注意的关键因素进行了分析。针对供电线路较长、断路器无法满足动作灵敏度校验的情况,给出了提高断路器动作灵敏度的解决方案。
In this paper,several methods for the selection of cable cross-sections are introduced.Combined with actual engineering examples,the key factors that need to be taken into account when selecting the BOP power supply cable crosssection for nuclear power plant are analyzed.For the case that the power supply line is longer and the circuit breaker cannot meet the action sensitivity check,the solutions to improve the sensitivity of the circuit breaker are given.
