喇七变1号主变绕组烧损故障分析与防控措施

Fault Analysis and Prevention and Control Measures of No.1 Main Transformer Winding Burning in Laqi Transformer

变压器是电力系统的核心设备之一,电网的安全可靠运行与其息息相关。变压器绕组短路烧毁事故严重影响了电网的安全、经济运行。通过对喇七变1号主变高压恻A相绕组烧损故障进行研究,分析了变压器短路损坏故障的原因,并针对变压器绕组匝间短路故障提出了有效的防控措施。

Transformer is one of the core equipment of power system,and the safe and reliable operation of power grid is closely related to it.The short-circuit burnout accident of transformer windings seriously affects the safe and economic operation of power grid.Through the study of the burnout fault of the high voltage Kay A phase winding of the No.1 main transformer of Laqi Transformer,the causes of transformer short-circuit damage are analyzed,and effective prevention and control measures are put forward for transformer winding inter-turn short-circuit fault.
