摘要：

Partial discharge inception voltage (PDIV) tests under sinusoidal and repetitive square voltages are critical measures to evaluate the insulation performance of inverter-fed motors working under pulse width modulation (PWM), and their comparison is worthy of attention. Under the sinusoidal and repetitive square voltages in the same frequency, a large number of comparative PDIV tests have been carried out on the meta-aramid which is used in the main insulation of the inverter-fed motor of new energy vehicles. The statistical methods are used to discover the primary source of the initial electrons that cause the streamer discharge in the PDIV tests of the ball-plate electrode structure and the distribution law of the first discharge in the meta-aramid fiber. Experimental results show that the PDIV of the meta-aramid depends on the peak-to-peak value of the voltage. The conservative PDIV can be obtained by using sinusoidal or repetitive square voltage with low overshoot. Under the repetitive square voltage, the energy of the discharge is concentrated at 0.2~1.4 GHz. Due to the influence of the relaxation and the test equipment, the test frequency should not be too high. This paper discusses the equivalence and difference between the first discharge and subsequent discharges, and gives suggestions for PDIV testing of meta-aramid under PWM voltage. ©2023 Chin.Soc.for Elec.Eng.
