快速真空开关合闸触头弹跳暂态过程研究

Gaoya dianqi
以电磁斥力驱动器作为操动机构的快速真空开关具有分闸速度快，分合闸时间短和分合闸时间分散性小的优势，目前已广泛应用于多种电力设备中。目前对于快速真空开关的分闸过程已有众多研究，但合闸过程的相关问题尚属空白。文中研究了快速真空开关合闸过程中触头弹跳问题。建立了多物理场耦合仿真模型，完整描述了快速真空开关的合闸过程。得到了快速真空开关的v1与Dmax的关系，其中v1为合闸过程中动静触头首次接触的瞬时速度，Dmax为动触头的最大弹跳距离。根据这一关系式，确定了合闸过程中无触头弹跳情况下的临界瞬时合闸速度vcri。

人 工 皮 Bio Fill®的 实 验 研 究

Zhongshan Daxue xuebao. Yixue kexue ban, 1998
目的: 人工皮 Bio Fill®( BF)在临床上应用效果较好。为探讨其作用机制,我们设计和进行了本实验研究。方法: ①用新西兰白兔 造成平均为体表面积 8. 74%的全层皮肤缺损的动物模型,在其创面上分别覆盖 BF 和生理盐水纱布,观察诸兔术后精神状态,并测定它们的基 础代谢、血清丙二醛和生化 8 项( Na、K、Cl、TCO2、Glu、BUN、Cr、Tp) ,观察其变化;②用液体接种法、平板接种法,分别接种金黄色葡萄球菌等 10 个致病菌种,观察 BF 的杀菌和防御细菌入侵能力;③用光镜观察用 ...
