摘 要：無功補償成套裝置中的串聯(lián)電抗器采用固體絕緣結構，針對其運行中匝間短路故障頻發(fā)且檢測手段不足問題，提出了基于損耗因數(shù)的串聯(lián)電抗器匝間絕緣監(jiān)測技術。分析了串聯(lián)電抗器發(fā)生匝間短路故障的原因，建立電抗器匝間短路等效電路，針對其故障特征研究了電抗器匝間短路監(jiān)測的技術方案，并通過有限元仿真軟件驗證了所提方案的可行性和有效性。
關鍵詞：串聯(lián)電抗器；匝間絕緣；損耗因數(shù)；監(jiān)測技術

Abstract: The series reactor in the complete set of reactive power compensation device adopts a solid insulation structure. Aiming at theproblems of frequent occurrence of inter-turn short-circuit faults of series reactors in reactive power compensation equipment and insufficientdetection methods, this paper proposed a monitoring technique for inter-turn insulation of series reactors based on loss factor. And the causeof the inter-turn short-circuit fault of the series reactor was briefly analyzed; then, the equivalent circuit of the inter-turn short circuit of thereactor was established, and the technical scheme of the inter-turn short circuit monitoring of the reactor was studied according to its faultcharacteristics; Finally, the feasibility and effectiveness of the proposed scheme are verified by finite element simulation software.
Key words: series reactor; inter-turn insulation; loss factor; monitoring technology
