小型水電站變壓器安全運行研究

摘要: 小型水電站的故障往往迫使電站停運, 影響電站的效益. 浙江天臺縣里石門水庫一級電站變壓器在運行管理中, 重點對變壓器聲音不正常、溫度顯著升高、油色異常、油位異常、變壓器過負荷等情況進行了技術分析和處理, 在變壓器安裝、運行、變壓器油的維護、運行人員素質培養等方面提出了行之有效的措施, 包括變壓器油校驗、嚴格安裝規范
和日常維護等, 實踐證明這些措施能確保小型水電站變壓器安全穩定運行.

Abstract :Based onthe failure analysis and the management experiences of transformers in Lishimen Reservoir of Tiantai County , Zhejiang,the causes andtreatments on abnormal operation of the transformer are introducedinthis paper , such as the thundering noise and
boostingtemperature of the transformer , the abnormal color and unconventional stage of the oil , overload operation and etc . The effective technological measures are also discussed , includingthe installationand operation of the transformer ,transformer oil maintenance , operators’on-job training ,in-time daily maintenance and some other aspects , which may ensure the safe and stable operation of transformers in small-sized hydropower stations .
