自复式过电压、欠电压保护器硬件、软件及应用

保护器,用于保护线路及线路中的用电设备.安装在单相交流220V线路的入口处,当线路发生过电压或欠电压时自动切断用电线路,当线路电压恢复正常时自动接通线路.克服了需要手动复位保护器的技术缺陷.着重阐述自复式过电压、欠电压保护器的设计要求、PIC12C672单片机的定义、硬件电路、主程序流程、主要技术指标以及在建筑民用住宅中的应用方法.

Self-recover Over and Behind Voltage Protector

The protector which is introduced in this essay is a protecting device which is used to protect the line and the devices on-line.It is fitted at the entrance of AC 220V and when over-voltage and behind-voltage take place it can be automatically cut off but when the electric pressure recovers its normal state it can be automatically switched on..Therefore,the advantage of this device is that it overcomes the shortcoming of Manual Acting Protective Devices.This essay lays great emphasis on the requirement for designing the protector of self-recover over-voltage and behind-voltage,definition of the PIC12C672 single-chip,the foundation of the hardware circuit,the main part of programming process,instructions and application.
