GB/T 22720.2-2019
ActiveRotating electrical machines—Qualification tests for the partial discharge resistant electrical insulation systems (Type II) used in rotating electrical machines fed from voltage converters
旋转电机 电压型变频器供电的旋转电机耐局部放电电气绝缘结构（Ⅱ型）的鉴定试验
Application Summary AI generated
This standard specifies qualification test methods for evaluating the partial discharge resistance of Type II electrical insulation systems in rotating electrical machines powered by voltage converters. It is applied in the design, manufacturing, and quality verification of motors and generators used in variable-frequency drive applications, such as industrial pumps, fans, and electric vehicle traction systems. The standard ensures insulation reliability under high-frequency voltage stress, preventing premature failure in inverter-fed machines.
