摘　　要：文章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,如相间接地、定子绕组开路、过负荷、失压、堵转、过热等,提出了基于ISPLSI及196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(ISPLSI1032E),使装置具有简洁、稳定、速度快、抗干扰性好、保护功能强等特点。The article analyzes the status when the electromotor is running.Ba se d on the electromotor's failure features,such as phase and ground fault,stator winding open circuit,overload,offset voltage and superheat etc.It puts forwa rd the project of practical electromotor protector that grounds on196series S CM,for instance zero sequence current protection,negative sequence current p rotection,positive sequence current protection,overload protection,superheat protection,offset voltage protection etc.It also puts up establishment and d erivation of mathematical model in algorithm.In addition to these,it carries t hrough optimistic design in hardware and software,especially introduces complex programmable logic device ISPLSI-1032E gate array,therefore the setting b ecomes more concise and stable.In all,the setting have many characteristics su ch as rapid velocity,nicer anti-jamming,powerful protection etc.
