摘要
为了防止电动机在使用过程中因过载、短路、断相、过压、欠压、过热而烧毁,有必要对电动机的运行状态进行及时准确的检测,并对电动机进行相应的保护。本文分析了电动机的故障原因,并介绍了多功能智能化电动机保护器的构成与保护功能的应用。
In order to prevent the motor from burning due to overload, short circuit, phase failure, overvoltage, undervoltage, overheating during operation, it is necessary to detect the running state of the motor timely and protect the motor. The paper analyses the failure cause of motor and introduces the structure and application of multifunctional intelligent motor protector.
