摘要
绕组变形是电力变压器正常运行过程中常见的一种故障隐患。准确诊断电力变压器绕组的变形情况,有助于保障电力系统的安全可靠运行。设计开发了一种兼具频率响应法和低压电抗法两种测量原理的变压器绕组变形综合检测仪器,其不仅可以满足频率响应法和低压电抗法的所有技术要求,而且结构轻便、操作简单,可方便地用于现场电力变压器绕组运行状况的有效检测和综合诊断。
Winding deformation is one common faulty and hidden danger in the normal operation of power transformer . It is good for ensuring power system safety and reliably operation by diagnosing the winding deformation condition of power transformer .This article designed and developed a transformer winding deformation synthetically detecting in-strument, which has two measurement theories , frequency response method and low voltage reactance method .This instrument is not merely to completely satisfy the technical requirement of frequency response method and low voltage reactance method , but also to have a portable structure and simple operation .It can be very convenient to effectively detect and synthetically diagnose the running condition of power transformer windings on site .
