Design and Realization of an Intelligent ...

This paper firstly introduced the working principle, combination switch- composite mode and implementation method, and designs the hardware system without power compensation by capacitor compound throw switch. According to the contactor and power electronic devices have problem in low voltage compensation of reactive power independent problems in application, Design of a capacitor switching composite switch it in order to PIC As the core and the thyristor and magnetic latching relay parallel main loop, it can realize fault diagnosis, recovery and indication function.
