摘要

交流滤波场对直交流转化过程中产生的谐波进行了抑制

是超高压直流工程中的重要部分。某±500 kV换流站发现多起交流滤波场的断路器均压电容故障

对功率输送产生了较大的影响。通过原因查找及试验测试

认为交流滤波场断路器的工况严苛

供货批次中出现的概率性劣品在内部压力骤然增大时发生击穿、炸裂

导致硅胶绝缘套穿孔、喷油。并对此故障提出了改进措施

以保障交流滤波场的正常运行

保证超高压直流输电的整体质量达标。

Abstract

The harmonics occurred during the conversion of DC-AC is restrained by the AC filter field

which is an important part of EHVDC project. Many grading capacitor faults of AC filter field circuit breaker are found in a ±500 kV converter station

which causes big influence in power delivery. Through cause investigation and test

the results show that the condition of AC filter field circuit breaker is severe

and the inferior parts will cause breakdown and breakage and lead to insulation rupture of silicon rubber and oil injection in case of increase in the internal pressure. The improvement measures are proposed so to assure normal operation of AC filter field and overall quality of HVDC transmission.
