Double power source auto switch
The national standards as well as the IEC standard the ATSE classification are the PC level and the CB level two ranks, because CB level ATSE has the volume to be big, the movement speed is slow, the mechanical interlocking reliability inferior shortcoming, its application domain is reducing gradually, but PC level ATSE because its structure is simple, the volume is small, own interconnection, the conversion rate is quick, safe, reliable has become ATSE the mainstream. This article is precisely from the ATSE developing process, the development trend and PC level ATSE obtains in the project application, has carried on the essential elaboration to PC ⅠⅠlevel ATSE. Key word: ATSE double power source automatic change-over; Mechanical interlocking; Electrical isolation; Time delay hypothesis; Non-title documents.

双电源自动开关

 国家标准以及IEC标准将ATSE分类为PC级和CB级两个级别，由于CB级ATSE存在着体积大，动作速度慢，机械联锁可靠性较差等缺点，其应用领域正在逐步缩小，而PC级ATSE由于其结构简单，体积小，自身联锁，转换速度快，安全，可靠已成为ATSE的主流。本文正是从ATSE的发展过程、发展趋向及PC级ATSE在工程中的应用入手，对PC级ATSE进行了必要的阐述。 关键词： ATSE双电源自动转换开关；机械联锁；电气隔离； 延时设定；无标题文档。
