船舶配电系统低压断路器保护协调性分析

Analysis on Coordination of Low-Voltage Circuit Breaker Protection for Marine Power Distribution System

本文阐述了在船舶配电系统中,低压断路器实现上下级电路协调性保护需考虑的因素及实现选择性保护的方法,包括电流选择性、时间选择性等。并且以8 000 hp三用工作船配电系统的保护断路器作为实例进行分析.

Taking 8 000 hp AHTS as an example, this paper analyses the major factors to be considered and the methods to achieve the selective protection of circuits by the low-voltage circuit breaker in marine power distribution system, including selection of current or time.
