一种触电漏电保护装置的硬件设计

Hardware Design of a Kind of Electric Shock and Electric Leakage Protection Device

介绍了触电漏电保护装置的工作原理,给出了系统中信号检测电路、放大电路、滤波微分电路、触电漏电鉴别电路及报警电路的工作原理图,该触电漏电保护装置可以把触电和漏电区分开来分别对待,并把触电漏电保护工作交由单片机控制,使装置趋于智能化。

Introduction was made to the working principle of electric shock and electric leakage protection device. This paper gave working principle diagrams of signal test circuit, amplification circuit, filter calculus circuit, electric shock and electric leakage defining circuit and alarm circuit in the system. The electric shock and electric leakage protection device could distinguish between electric shock and electric leakage and treated them respectively, delivering electric shock and electric leakage protection to single chip for control, to make the device intelligentize.
