摘　　要：根据低压屏蔽法的原理 ,配以大功率中频电源和改进的过电压保护装置等 ,开发轻便、操作简捷的成套试验设备。克服了水内冷发电机定子绕组直流耐压试验吹水法和组合设备通水法的缺点 。The shortcomings of HVDC test of water internal. cooled stator windings of power generator under water blown off condition and under circulating cooling water condition by using combined test devices are analyzed. A portable complete HVDC test set, which is easy for operating is developed based on low voltage shield method with large power medium frequency converter and special designed overvoltage protection device.
