摘要
本文介绍了一种矿用电机温度变化率和电机定子绝缘阻值在线控制监测装置,实现了对矿用大型电机在启、停阶段的绝缘监测和保护,延缓了电机定子的绝缘因温升引起的损害,延长了电机的使用寿命。从而减少现场维修人员劳动强度,通过485通讯口,可以并入煤矿井下自动化监控网,提高现场检测的自动化水平。
This paper introduces the on-line insulation monitoring device of the resistance control of motor stator and the mine electric rate of change of temperature, implementing the insulation monitoring and protection of mine large motor in the stopping and opening stage, delaying the insulation motor stator temperature rise caused by damage, prolonging the service life of motor, and reducing the labor intensity of field repair personnel, through the 485 communication interface, it can be incorporated into the automatic monitoring network in coal mine underground, to improve the level of automation field detection, suitable for all kinds of motor system locale.
