| Abstract: | A analysis is made on the defect between the excitation carbon brush and slip ring of 4 Kaplan turbine generator units in Shenxigou Hydropower Station since their commissionings, and then an anti dropping device is researched and developed, which is already adopted on the generator units of Shenxigou Hydropower Station and can effectively prevent the dropping of the carbon brush and causing earthing of rotor or short circuit of positive and negative poles during the operation. |
