摘要
针对船用智能型万能式断路器在船舶潮湿、盐雾、霉菌环境中,需要进一步提高智能脱扣器可靠性、稳定性的问题,研究了一种用于某智能型万能式断路器后备保护的电磁瞬动保护装置。装置整体结构采用模块化设计,方便维修更换;断路器瞬时保护动作响应快,缩短分断时间,提高了断路器短路分断能力,从而作为智能脱扣器的后备保护,增强了断路器保护功能的可靠性。
Intelligent air circuit breaker is a very important device in ship power system. This article described the electromagnetic instantaneous protection device for a certain type of intelligent air circuit breaker. The overall structure of the device uses a modular design for easy maintenance and replacement; while the breaker instantaneous protection rapid response action reduces the breaking time, which improves the circuit breaker＇ s short-circuit breaking capacity. As a backup protection, it enhances the reliability of the circuit breaker＇ s protection function.
