结露现象会导致绝缘的水分增加,使隔热能力急剧下降。长时间的结露会造成隔热材料的永久性损坏,同时会造成室内积水,环境潮湿。因此防结露设计是船舶舱室隔热设计的一个重要组成部分。文中对《船舶设计实用手册(舾装分册)》中的防结露计算方法进行了细化和分析,结合陆用规范的冬季保温设计对手册防结露的计算方法提出了一些修正方案,并对传统的隔热材料节点形式进行优化设计。 相似文献

针对传统船舶电网绝缘监测装置可靠性不足、受泄漏电容的影响较大、测量范围较窄、测量准确度不高等问题,以船舶IT交流供配电网络为研究对象,建立一种能够实时监测整个电网系统对地绝缘值与泄漏电容值,实现实时故障定位的系统,并结合Hausdoff距离算法进行容错计算.结果 表明:该系统可实时监测船舶电网的绝缘状态,并实现故障线路的准确定位,为操作人员保养设备和抢修设备提供最及时、最准确的判断信息,能够做到尽快排除故障,恢复供电,保证机电设备随时处于备航状态. 相似文献
