摘要
超高压电力变压器的现场操作波感应耐压试验,在我国许多地区已经开展多年,并取得了一些成效,发现了一些绝缘缺陷。本文对变压器操作波感应耐压试验的某些技术问题,如波形采用IEC标准以及测量技术的改进等,进行了论述。
High-Voltage switching surge field test for power transformers in extra 1H-V power system of China has been developed for years.Some defects oftransformer insulation were detected.In this paper,some technical problemssuch as changing the existing domestic standards of waveshape andimproving the measuring methods are proposed.The selection of suitable digital oscilloscops which should be widely used in the measurements of voltageand detective current is discussed.
