中小型交流电机自动检测保护装置的研制

DESIGN FOR MIDDLE SMALL SCALE ALTERNATING CURRENT MOTOR PROTECTION DEVICE

介绍了一种用于发电机组、电机等设备在线故障检测和保护报警的控制系统．该系统采用以８０９８单片机为核心的控制器件及其外围电路，通过对电压、电流采样并对检测到的参数进行处理，实现了自动检测、故障自诊断、保护报警以及在线设置参数等功能．它可以降低成本，减少组装和调试工作，缩小控制屏体积，减少内部构件，效益明显．

The kind of practical system for detecting and alarming of on line breakdown is presented.This system is composed of 8098 microcomputer and its periphery circuits,the followed functions can be realized by sampling voltage and electric current:on line breakdown detecting ,breakdown self diagnosing,display,protecting,etc.Using this system can reduce costs,decrease some work of debugging,narrow the measurement of screen,the benefit is evident.
