摘　　要：本文中笔者对分接开关整体结构进行合理简化,建立了有载分接开关磁-热耦合的有限计算模型。对换流变有载分接开关磁热耦合仿真进行了计算分析,分析了漏磁集中分布特性、欧姆损耗与漏磁损耗对温升的影响特性。The overall structure of tap changer is simplified, and the finite calculation model of magnetic thermal coupling of OLTC is established. The magneto thermal coupling simulation calculation and analysis of the OLTC of converter transformer are presented, which reveals the centralized distribution characteristics of magnetic flux leakage and the influence characteristics of ohmic loss and magnetic flux leakage loss on temperature rise.
