Abstract: 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.
Key words: generator; condition assessment; no pumping rotor; guide rail; air gap-free baffle
