Application of Three-Phase Intelligent Complex Switch Used in No-Power Compensation
Liang Yezong · Low Voltage Apparatus · 2008
An intelligent complex switch used on low-voltage and no-power compensatory device was indtroduced.It adopts a parallel structure of thyristor and magnetic latching relay.The thyristor and the relay will be on at different time,so the complex switch has the strong point of silicon-controlled rectifier which has the quickly response and high dependability and the magnetic latching relay which has low power,and the switch solve the pro-blems when the capacitor plunge into or remove from the three-phrase power.
