SGQ ATS can make fast loading transfer (transfer time ≤80ms) under two ways power supply. Also ATS can be widely used in Hi-buildings, post, telecommunications, mines, ships, medical, public health, military installations, and so on. Two ways power can be mains, gens and storage battery.5 STRUCTURESmartgen SGQ Automatic Transfer Switch (ATS) apply for structure of magnet coil driving and two ways interlocking of electric and mechanical. And ATS’s major contact structure is two-stable and one-moving, and the moving contact is “V” type design, in order to ensure there is no short circuit of the two-ways power supply. “N” and “T” apply for structure of single coils operation and the coil only have current while it is transferred, and this can extremely extend theYPE “N” CASE DIMENSIONS AND TECHNICAL DATARIGHT VIEWSpecification Case size Installation size Cupper bar(A) A2P A3P A4P D C B2P B3P B4P E M U TQ63N 172 200 228 186 155 139 167 195 165 5 12 27 Q125N 193 228 265 186 155 159 195 231 165 7 20 37“N” technical data6.3.

Protection and preventive measures must be considered during the operation. The wires connection of switch major loop must make its down lead prohibit from any pressure and strong force. Should inspect if have any damage to switch or any harmful environment before installation or debugging. Meanwhile, should check the wires connection if loose during transportation. Also should make the switch is clean and clean way smudge, special prohibit any smudges on the surface ofinsulation parts. The smudges could be caused from the packing materials during transportation or in storage. When connect main loop, should make the two-ways power phase sequence as same. Also should strictly follow to wires diagram in manual when connect to second loop and pay attention to control the voltage grade of power. There must be have excellent ground-connection when installation. Considering the personal safety and quickness of switch transfer, the debugging handle for testing only and users never operate it with load. Should use handle to operate the switch first when debugging. If everything goes well, using manual button to power-driven operation. And ATS is normal running after there is no error.。

转换一旦失败将会造成多种危害，电源间的短路或重要负荷断电，其后果都是严重的，这不仅仅会带来经济损失，也可能造成社会问题。
就其目前的发展现状来看，对双电源自动转换开关的研制和生产已是刻不容缓。
否则，就无法满足因人们生活质量的不断改善而对电源可靠性的要求越来越迫切，功能更完善的发展要求。
本文首先分别介绍了自动切换器的电气控制原理和机械系统的结构设计，并相应地给出了系统框图和控制系统硬件原理框图。

施耐德万高技术支持技术支持Q&A技术支持1.1 综述1. 双电源自动转换系统中CB级和PC级分别是什么意思？施耐德是哪一类的产品?在双电源转换系统中，PC级是指能够接通、承载、但不用于分断短路电流的双电源转换系统（无过电流保护）；CB级是指配备过电流脱扣器双电源转换系统，它的主触头能够接通并用于分断短路电流(即具备短路过载保护功能)。
施耐德电源转换开关产品中既有CB级（WATSN、ATNSX、ATMT、WSATS）的产品，也有PC级（WOTPC、WBTPC、WTS、WATSG、WATSN、WSATS）产品。
2. 自动转换开关电器常用使用类别怎样选用?使用类别：ATSE(自动转换开关电器)常选用AC-33A、AC-33B、AC-33 iA、AC-33iB作为其使用类别。
AC-33 iA、AC-33iB含义是：系统总负荷包含笼型电动机及阻性负载。
AC-33A、AC-33B含义是：电动机负载或包含电动机、电阻负载和30%以下白炽灯负载的混合负载。
其中A表示频繁操作，B表示不频繁操作。
3. 建筑消防电气设计上有没有对电源切换的要求, 如果有应设置在什么位置？火灾自动报警、消防通信等消防用电设备均设有应急电源。
当使用的电源故障停电时，被停止供电的重要负荷采用电源自动切换装置(ATS)切换至另一电源。
《高层民用建筑设计防火规范》第9.1.2条规定：“高层建筑的消防控制室、消防水泵、消防电梯、防烟排烟风机等的供电，应在最末一级配电箱处设置自动切换装置。
4. 首端与末端设置转换开关的不同点？ATS设在首端 (如在变电所低压的第一级配电处)和设在末端相比，末端设ATS时，除了电源故障停电能自动切换外，当配电设备故障或低压线路上发生故障而停电时，末端ATS也能动作，增加了负荷的供电可靠性；首端设ATS时，如果配电设备或低压线路发生故障而停电，该ATS不动作，这样就无法保证负荷的继续供电，所以末端ATS比首端ATS更为可靠。
