摘要
Abstract
The on-load tap-changer of converter transformer is the core component to realize voltage regulation of converter transformer and plays an important role in ensuring the voltage stability of power system.With the develop-ment of VSC DC transmission technology,the switching load current with harmonic component by the on-load tap-changer is becoming more and more prominent.The switching operation is often performed under the complex condi-tion of multiple harmonic superposition.Therefore,the zero point of the switched load current will have a large cur-rent variation rate,which significantly increases the switching load of the tap-changer.It in particular poses a great challenge to the current transfer capability of the vacuum interrupter in the vacuum type on-load tap-changer.There-fore,the corresponding test technology research on the verification of the harmonic current switching capacity of the vacuum type on-load tap-changer for converter transformer is performed in this paper,and the performance verifica-tion is developed through the established harmonic current switching test condition.The obtained test results and analysis content will provide technical support for the establishment of a harmonic current switching performance as-sessment method for vacuum type on-load tap-changer.关键词
