摘要
±800 kV灵州特高压阀侧角接换流变压器现场交接试验前,根据阀侧角接换流变压器特点,分别对试验原理、所用仪器、参数计算及现场试验进行介绍,并对各环节的注意事项进行总结,验证了该研究的可行性及适用性,且为其他换流变压器感应耐压及局部放电试验提供参考。
Prior to the on-site handover test of converter transformers with delta valve windings in±800 kV Lingzhou UHV converter station,the test principle,instruments,parameter calculation and field tests were introduced according to the characteristics of the transformers.In addition,points for attention in the links were summarized,and feasibility and applicability of the research were verified to provide a reference for inductive withstand voltage and PD(partial discharge)tests of other converter transformers.
