变压器抗短路能力校核不合格原因分析及治理措施研究

Analysis of Unqualified Check for Anti-short-ircuit Ability of Transformers and Research on Treatment Measures

摘要:

变压器抗短路能力校核是评估大型电力变压器抗短路能力的重要方法。文中对4台220 kV变压器进行抗短路能力校核，对校核结果不合格的原因进行了分析；针对抗短路能力不足的变压器提出通用治理策略，建议结合变压器诊断性电气试验及油色谱试验评估变压器状态，制定针对性的治理措施。

Abstract:

Checking the anti-hort-ircuit ability of transformers is an important method to evaluate the anti-hort-ircuit ability of large power transformers. The anti-hort-ircuit ability of four 220 kV transformers are checked, and the reasons for their unqualified check are analyzed. A general treatment strategy is proposed for transformers with insufficient anti-hort-ircuit ability. It is recommended to evaluate the transformer status by diagnostic electrical test and oil chromatography test, and to formulate the targeted treatment measures.
