■ 使用注意事项
电机保护器类型在电动机工作条件下的选择 1、对于工作条件要求不高、操作控制简单，监护、管理比较随意，停机对生产影响不大的单机独立运行电动机，可选用普通型保护器，因普通型保护器结构简单，在现场安装接线、替换、操作简单、方便，具有高等特点。
2、对于工作条件要求很高，安全性和连续性又很关键的，而自动化程度高，且需要专人控制、监护、管理，需组网监控的MCC系统中，应选用中*、功能较全的保护器。
3、对于防爆电机，由于轴承磨损造成偏心，可能导致防爆间隙处摩擦出现高温，产生爆炸危险，应选择磨损状态监测功能。对于大容量高压潜水泵，由于检查维护困难，也应选择磨损状态监测功能，避免发生扫膛事故造成重大经济损失。
