摘　　要：本文在分析了电动机运行状况的基础上 ,根据电动机常见的故障特征 ,如相间和接地故障、定子绕阻开路、过负荷、失压、堵转、过热等 ,提出了基于ISPLSI及 1 96系列单片机为核心的实用电动机保护方案 ,具有零序保护、负序电流保护、正序电流保护、过载保护、堵转保护、过热保护、失压保护等功能。在算法上进行了数学模型的建立和推导。在硬件、软件上进行了优化设计 ,特别是采用了在系统可编程逻辑器件 (ISPLSI1 0 3 2E) ,使装置具有简洁、稳定、速度快、抗干扰性好。The article analyzes the status when the electromotor is running. Based on the electromotor’s failure features, such as phase and ground fault, stator winding open circuit, overload, lock of voltage and superheat etc. It puts forward the project of practical electromotor protector grounded on 196 series SCM, for instance zero sequence current protection, negative sequence current protection, positive sequence current protection, overload protection, superheat protection, lock of voltage protection etc. It also puts up establishment and derivation of mathematical model in algorithm. In addition to these, it carries through optimistic design in hardware and software, especially introduces complex programmable logic device ISPLSI-1032E gate array, therefore the setting becomes more concise and stable. All in all, the setting have many characteristics such as rapid velocity, nicer anti-jamming, powerful protection etc.
