　　ATS自动转换开关

　　ATS automatic conversion switch

　　ATS主要用在紧急供电系统，将负载电路从一个电源自动换接至另一个（备用）电源的开关电器，以确保重要负荷连续、可靠运行。ATS为机械结构，转换时间为100毫秒以上，会造成负载断电。适合照明、电机类负载。

　　ATS is mainly used in the emergency power supply system, which automatically switches the load circuit from one power supply to another (standby) power supply to ensure the continuous and reliable operation of the important load. ATS is a mechanical structure with a switching time of more than 100 milliseconds, resulting in power failure. It is suitable for lighting and motor load.

　　其中负荷开关派生的自动转换开关采用双列复合式触头、传动机构、微电机预储能、以及微电子控制技术，基本实现了零飞弧。驱动电机为聚氯丁橡胶绝缘湿热型电机，装有安全装置在超出110℃温度和过电流状态时自动跳闸。待故障消失后即自动投入工作，很大程度保证了开关寿命。

　　The automatic conversion switch derived from load switch uses double column compound contact, transmission mechanism, micromotor pre storage energy, and microelectronic control technology, and the zero fly arc is basically realized. The driving motor is polychloroprene rubber insulated wet heat motor, equipped with safety device to automatically trip when exceeding 110 C temperature and over current. When the fault is gone, it will automatically work and ensure the life of the switch to a large extent.
