中文摘要 | 台電某一發電廠之部分發電機昇壓變壓器絕緣油帶電度異常,而影響其 運轉。本文乃首先探討帶電度發生之主要因素與大型高壓變壓器油流帶電引起之 事故案例;其次說明研購之迷你型絕緣油帶電度測定器進行帶電度之量測,探討 帶電發生要因;最後提出油流帶電之防制策略與改善建議。 |
英文摘要 | Some step-up transformers which used in a Taipower's power plant havebeen detected an abnormal charging tendency in insulation oil, which mayinfluence transformer stability. In this paper, we discuss the primary factorcausing static electrification of insulating oil and its effects on largetransformers. Then, the Mini Static Tester, which is used to test insulatingoil electrostatic charging tendency, is described. Finally, some suggestions toavoid transformer failure caused by higher charging tendency are presented. |
