摘要

较大的异步电动机必须配备差动保护，以防止电动机绕组上的短路。一个非常有趣和非常规的解决方案是在差动保护功能中使用过流保护。通过应用这种解决方案，我们获得了非常精确和敏感的保护，没有失真，不容易受到干扰。这将提高异步电动机保护的可靠性。

Motor Overcurrent Protection in the Function of a Differential Protection

Larger asynchronous motors must be equipped with a differential protection providing protection against short circuits on the motor winding. A very interesting and unconventional solution is the use of the overcurrent protection in the function of the differential protection. By applying this solution we obtain a very precise and sensitive protection without distortion and not susceptible to interference. This will result in increased reliability of asynchronous motors protection.
