变压器短路线圈机械强度研究及短路试验技术

Research on Mechanical Strength of Transformer Short Circuit Coil and Short Circuit Test Technology

以电力变压器产品的短路试验方法和产品合格判定标准为切入点,在分析短路情况下线圈受力的基础上,通过有关短路试验技术的深入分析,合理确定在发生故障时线圈机械强度的变化,制定可操作性较强的电力变压器抗短路能力的措施,为系统故障识别和处理提供参考。

Based on the short-circuit test method of power transformer product and the qualification criterion of powertransformer, based on the analysis of the force of the coil under the short-circuit condition, the paper analyzes theshort-circuit test technology deeply. The variation of the mechanical strength of the coils in the event of fault isreasonably determined, and the measures of anti-short-circuit ability of power transformers with strong maneuverabilityare worked out, which provides a reference for the identification and treatment of system faults.
