| description | The invention relates to a current-based longitudinal differential protection method and system for a belt conveyor, which are used for protecting the belt conveyor during operation. The method comprises the following steps of periodically collecting the current value of the belt conveyor, and judging whether the belt conveyor is in no-load operation or not, if yes, protecting the belt conveyor through the no-load protection step, and if not, protecting the belt conveyor through the load protection step. Compared with the prior art, the method has the advantages of high accuracy, high reliability, good safety, strong timeliness and the like.
本发明涉及一种基于电流的皮带机纵联差动保护方法及系统，用于皮带机运行时对其进行保护，方法包括：周期性采集皮带机的电流值；判断皮带机是否为空载运行，若是则通过空载保护步骤对皮带机进行保护，否则通过负载保护步骤对皮带机进行保护。与现有技术相比，本发明具有准确性高、可靠性高、安全性好和及时性强等优点。 |
