矿井主通风机电机碳刷总成改造设计

Transformation Design of Carbon Brush Assembly for Mine Main Fan Motor

为矿井安全生产提供支持,对主通风机电机的励磁碳刷固定架结构进行改造。通过改造有效地解决了原结构碳刷与滑环在工作过程中容易冒火花、碳刷磨损不均匀的问题,实现了碳刷工作温度异常的实时报警、碳刷达到磨损限位值时进行警示与提醒更换的功能。

In order to provide support for mine safety production,the main fan motor excitation carbon brush fixed frame structure was reformed.The problems of sparking easily and uneven wear of carbon brush and slip ring in the working process are effectively solved through the transformation.The real-time alarm of abnormal working temperature of carbon brush and the function of warning and replacement when the carbon brush reaches the wear limit are realized.
