摘要
根据船舶中压电力系统的特点,对中压断路器开断性能密切相关的参数进行了分析。结果表明,陆用标准中额定短路开断电流和关合电流、工频恢复电压和瞬态恢复电压、电寿命等参数经过换算、折算,基本上符合船用要求,个别参数是否合适有待进一步研究。
According to the characteristics of marine medium voltage power system, the parameters closely related to the breaking performance of medium voltage AC circuit breaker were analyzed. It is shown that the key performance parameters in land standards, such as rated breaking current, making current, power frequency recovery voltage, transient recovery voltage, electrical life and so on, basically meet the marine requirements after conversion. But there are also some individual parameters need to be studied further to decide.
