摘要
在梳理发电机大修所需开展的检修和试验项目的基础上,提出了一种发电机大修状态评估测试方法,该方法以利用转子护环端部进行固定的分段拼接式塑料导轨和定制式载具为试验工具,配合高清补光型变焦距摄像头、Chattock线圈和定子槽楔松紧度检测探头等传感器和测量设备,实现了无气隙挡板发电机在不抽转子条件下完成大修状态评估测试的目的。现场应用测试表明,该装置效果良好,应用前景广阔。
On the basis of reviewing the overhaul and test items required for generator overhaul,a method for assessing the condition of generator overhaul is proposed.This method uses fixed segmented spliced plastic guide rails and the custom-made vehicle as a test tool,with sensors and measuring equipment such as HD fill light zoom camera,Chattock coil and stator slot wedge tightness detection probe,etc.,and the purpose of the air gap-free baffle generator to complete the overhaul condition evaluation test without pumping the rotor is achieved.Field application tests show that the device works well and has broad application prospects.
