GB/T 22720.2-2019 《Rotating electrical machines—Qualification tests for the partial discharge resistant electrical insulation systems (Type II) used in rotating electrical machines fed from voltage converters》 Related products

The GB/T 2 2720.2 - 2019 standard focuses on the field of swirl/spin motors, mainly for the electrical insulation structure (type II) that is resistant to partial discharge in swirl/spin motors powered by voltage-type inverters. The standard specifies the relevant content of the identification test of such insulation structures, aiming to ensure the Reliability of the insulation structure of this type of swirl/spin motor in actual operation by standardizing the test process and requirements. It provides an important basis for the design, production and mass inspection of swirl/spin motors.
