    • An electrical automatic transfer switch (100) having a thermal overload protection function is disclosed. The electrical automatic transfer switch (100) includes an electrical switch unit (30) formed of a semiconductor switching device, and an assistant switch unit (110) formed of a non-heating device connected with the same inparallel. A switching operation for a switch between a constant power and an emergency power is performed when the phase of a power voltage is zero using a semiconductor switching device (TR30). The continuous supply of power voltage is performed through an assistant switch unit (110). A heating phenomenon does not occur at a semiconductor switch device (TR30) by power supplied to the load after a switching operation is performed. A radiating plate is not needed, do that a small size system can be fabricated.
    • 公开了一种具有热过载保护功能的电动自动转换开关(100)。 电自动转换开关(100)包括由半导体开关装置形成的电开关单元(30)和由与其并联连接的非加热装置形成的辅助开关单元(110)。 当使用半导体开关装置(TR30),当电源电压相位为零时,执行用于恒定功率和紧急电力之间的开关的切换操作。 通过辅助开关单元(110)执行连续供电电源。 在切换操作之后,通过向负载提供的电力,不会在半导体开关装置(TR30)处发生加热现象。 不需要散热板,可以制造小尺寸的系统。
