In a induction motors fed by a PWM voltages sour ce inverter, the insulation system endures much higher stresses, so that its rel iability will be affected. 與電網(wǎng)供電相比，變頻器供電的異步電機絕緣系統承受了更高的應力，因而有必要以新的標準對變頻電機的絕緣系統進(jìn)行重新考慮。
Multifactor aging of HV equipment insulation sysem is introduced in this paper, as well as various life models of insulation materials and systems. 簡(jiǎn)介了高壓電氣設備絕緣系統在多種應力聯(lián)合作用下的老化規律及各種壽命模型。
