在某皮带运输监控系统中，需要对电机电流进行检测以实现对电机的过流保护。在常规反时限过流保护特性的基础上，结合电机保护实际情况，提出一种适合在皮带运输监控系统上实现的微机型的改进反时限过流保护算法，并计算出过电流保护的动作时间，给出整定系数。此算法计算量小，易于实现，能够满足实际功能要求。目前已在某焦化厂的皮带运输监控系统中应用，经测试实验能够满足实际功能要求，电机的机电保护性能得到大大增强

In a monitoring and controlling system for belt conveyers,motor- current is measured for overcurrent protection. Introduces the traditional implementation arithmetic of inverse- time overcurrent protection. On this basis, a new time- current function suitable for the microcomputer - based inverse - time overcurrent protection was proposed. And this paper gives the operation time of inverse - time over- current protection. The arithmetic is easier to be realized and has better performance. At present, a cokeoven plant used the arithmetic. Motor＇s performance has been enhanced
