摘　　要：在轨道电路设备中,防雷变压器的Ⅰ,Ⅱ次绕组间,绕组与屏蔽层之间,设备外壳与大地之间的结构均类似于空气间隙。因此,笔者利用COMSOL软件对ZPW-2000A轨道电路中的防雷变压器进行了有限元仿真计算,分析绕组间间隙和两相体环境对绕组间电容数值的影响,以及绕组间加屏蔽层对绕组对地电容数值的影响。并对ZPW-2000A轨道防雷变压器进行了高海拔环境下雷电响应试验研究。In track circuit equipment,the structures between I and II secondary windings of lightning protection transformer,between winding and shielding layer,and between equipment shell and earth are similar to air gap.Therefore,theauthor uses COMSOL software to carry out the finite element simulation of lightning protection transformer in ZPW-2000 A track circuit,analyzes the influence of the gap between windings and two-phase environment on the capacitance between windings,and the influence of shielding layer between windings on the capacitance between windings to ground.The lightning response of ZPW-2000 A track lightning protection transformer in high altitude environment is studied.
