机电一体化自动转换开关设计 摘 要 机电一体化双电源自动转换开关是开关家族中的新品，主要应用于需连续供电的某些重要场所。 本文主要介绍了机电一体化双电源自动转换开关的电气控制原理和机械结构设计。其次结合理论和设计经验，分析了自动切换器的可靠性和安全性。其中，可靠性与安全性分析，既是本课题的重点，也是检验本课题研究对象是否合格，衡量设计结果有无意义的一关键所在。通过理论（分析）和计算，可以得出以下结论： 机械系统的结构，既保证了常用电源与备用电源只有一个供电，也可手动，电动联锁，通过机械联锁，保证系统的可靠性和安全性。 综上所述，系统能比较准确地测量各相电压参数，根据测量结果产生相应执行动作。整个机构设计简单，动作准确，使用方便，可靠性好，能满足设计要求。该产品具有很好的发展前景和现实意义。 关键词：机电一体化；自动转换开关；断路器；触发器；可靠性 Abstract Automatic transfer switching equipment is mainly used for critical imply of the power, which is one of switching equipment that transfer the power from one load to another. At first the paper respectively introduces the electric control principle of automatic transfer switching equipment ﹙ATSE﹚and the framing design of mechanical system, and then correspondingly gives the system framing chart and the principle framing chart of hardware of the electric controlling system. Next, combining with theory and the experience of designing, analyze the reliability and the safety of ATSE, which is not only one point of the research, is also one key point to measure if the research makes sense. By theory and amount of count, we can make the flowing conclusion. The framing of mechanic system makes sure that between utility power and the generator only one of them provides electricity to keep on the reliability and safety of the system. Above of all, all mechanism, designed simply, acting accurately and reliably, employing conveniently. The product is having good foreground and practical significance. 目 录 第1章 绪论……………………………………………………………………………1 1.1 课题概况………………………………………………………………………1 1.1.1 当前双电源转换开关的现状……………………………………………1 1.1.2 双电源转换开关的发展……………………………………………………2 1.1.3研究本课题的目的及意义…………………………………………………2 1.2 课题研究的内容………………………………………………………………3 1.2.1课题研究涉及的有关概念…………………………………………………3 1.2.2课题研究的主要技术性内容………………………………………………3 第 2 章 系统方案确定及控制原理………………………………………………5 2.1 系统方案确定…………………………………………………………………5 2.1.1 自动转换开关的组成………………………………………………………5 2.1.2 系统方案的确定……………………………………………………………5 2.2 开关结构特点及功能…………………………………………………………5 2.2.1开关结构特点………
