摘要
该文介绍了一种用瑞萨R8C25系列单片机控制的智能式低压电力电容器,能够通过新型复合开关对三相电容器进行快速、准确投切,解决电容投切时由于冲击电流过大而导致损坏电容的问题,一个装置同时达到过零投切、微机保护、电力测量、网络通信、智能控制等功能。
An intelligent low-voltage power capacitor controlled by Renasas R8C25 SMC is introduced,which can switch three-phase power capacitors quickly and accurately by a kind of new composite switch.The device solves the problem of capacitor damage due to the large impulse current when switching,and can realize the several functions such as zero-crossing switching,microcontroller protection,power measurement,network communication and intelligent control at the same time.
