以转换动作时间选择转换开关

Selection of Transfer Switch Pursuant to Switching Time

双电源供电系统的建立和自动转换开关的使用,目的是确保用电负载不因供电中断而影响工作。转换动作时间不单是自动转换开关的重要参数,也是双电源供电系统供电连续性的指标。本文从转换动作时间这一参数上区分3种形式的转换开关:自动转换开关(ATSE)、静态转换开关(STS)和瞬态转换开关(TTS)的不同和应用。

The purpose of double power supply system and ATSE is to make sure that the load is not affected by power interruption.The operating transfer time is not only an important parameters of ATSE,but also a criteria of supply continuity of double power supply system.Three types of transfer switches including Automatic Transfer Switch Equipment(ATSE),Static Transfer Switch(STS)and Transient Transfer Switch(TTS)are differentiated in terms of operating transfer time.
