摘要
针对微机型电动机保护进行了保护功能的描述及具体定值计算,并对其应用做出分析,指出了感应型反时限特性的电动机保护在应用中存在的弊端,提出大型电动机应配备新型微机保护以适应生产需求。
In view of the practical application of microprocessor-based motor protection, the protection of functional description and the specific setting calculation are analyzed. The characteristics of induction anti-time limit of motor protection existing defects in the application are put forward that new PC should be equipped with a large motor protection to meet production demands.
