Overhead grounding wire monitoring device

The utility model relates to a ground wire monitoring method for an overhead line of an open-air stope, and in an overhead ground wire monitoring device, a ground wire monitoring relay, an overhead ground wire, an overhead monitoring line and a resistance box are connected to form a ground wire monitoring system, so that the problem that the broken ground wire of the overhead line of the open-air stope is difficult to find is solved. The purpose of safety of electric equipment and personnel in the stope is achieved. 本实用新型涉及一种露天采场架空线路接地线监测方法，一种架空接地线监测装置利用地线监测继电器、架空地线、架空监测线、电阻箱相连组成接地线监测系统，解决了露天采场架空线路接地线断线不易发现的问题，实现了采场用电设备及人员安全的目的。
