1、（2）Twin Contactor Type（3）Twin MCCB/ACB Type（4）Power Contactor Type（5）State Transfer SwitchATS的结构类型典型ATS结构Knife Blade非负荷阻断通常是手动操作（速度很慢）有时也有电机操纵（速度也一样慢）低町承受率-无灭弧沟槽和通孔低耐久，寿命有限Twin ContactorNE1L2dkIIEC 60947-4-1开关设备有一个处于休眠状态（IEC标准定义）Returns to position of rest loss power （un-latched type） or add1! latch
2、ing arrangement to hold position on loss of power基于IEC 6094741代码标准提供非常简单的控制器无机械保险装管/安全互锁装置（选件）操作的多样性，从电机到电磁石非真正的双掷设备-可能两路电源都合上备注:IEC是国际电工委员会的简称Twin MCCB / ACB （Molded Case Circuit Breaker/ Air Circuit Breaker）2个开关装置，典型的有外加电机操作-基于使用I EC 60947-2代码标准1至多2型的断路器（基本的瞬间跳闸型）-机械保险装置/安全互锁装置是另加的有的是选件电机动作通常比较慢.重
3、负荷常常不可靠.有比较大的可指定可承受率（低冲，高）-非真正的双掷设备-可能两路电源都合上Power Contactor Type （GE Zenith Std.）/ji? UnderwritersLaboratories Inc.IEC标准双掷机械结构_固有的机械联锁装置避免两路同时合上 无需另加联锁装置 较少的动作部件高可承受电流率吋满足故障排除需求 完整的灭弧装置螺线管操作（动作快速）Static Transfer Switch（STS）需要存在2路电源固态开关无移动的部件 操作非常快速，转换时间小于仏周期.SCR技术何控硅）典型应用于有2路町靠独立电源的重要负荷或者切换2组UPS的输出
