产品简介
NABX全自动变压器绕组变形测试仪(频响法)用于测试6kV及以上电压等级电力变压器及其它特殊用途的变压器,电力变压器在运行或者运输过程中不可避免地要遭受各种故障短路电流的冲击或者物理撞击,在短路电流产生的强大电动力作用下,变压器绕组可能失去稳定性,导致局部扭曲、鼓包或移位等变形现象,这样将严重影响变压器的安全运行。按电力行业标准DL/T911-2004采用频率响应分析法测量变压器的绕组变形,是通过检测变压器各个绕组的幅频响应特性,并对检测结果进行纵向或横向比较,根据幅频响应特性的变化程度,判断变压器绕组可能发生的变形情况。
NABX变压器绕组变形测试仪(频响法)由测量部分及分析软件部分组成,测量部分是由信号生成及信号测量组成的黑匣子,分析部分由笔记本电脑完成,测量部分通过USB或网络与笔记本电脑连接。

Product introduction
NABX transformer winding deformation tester based on transformer internal winding characteristic parameters measurement, adopting the developed countries internal fault frequency response analysis (FRA) method, able to make accurate judgments on the transformer internal fault. Once the transformer is manufactured, its coil and the internal structure is stabilized, therefore to a multi- winding transformer coil, if the voltage level is same, with the same windling method, around the system in the same way , the corresponding parameter of each coil (Ci, Li) should is determined. Thus each coil resulting frequency domain response is determined , which corresponds to the frequency spectrum between the three-phase coils having a comparable. Transformer turns occurs during the test , the interphase short circuit or a collision during transport , resulting in the relative displacement of the coil , and the short-circuit during operation and the fault condition causing the coil deformation due to the electromagnetic force , will make the distribution parameters of the transformer windings change. Thereby affecting and changing transformers original frequency domain characteristics, namely the frequency response and resonant amplitude variations occurring frequency offset and so on. And according to the response analysis method developed NA201 transformer winding frequency response tester, is such a novel transformer internal fault nondestructive testing equipment. It is suitable for 63kV ~ 500kV power transformer internal structure fault detection. Transformer winding deformation tester is inside the transformer winding parameters at different frequency domain response changes were quantified after treatment , according to the magnitude of the changes the size , frequency response magnitude of change , regional and response trends to determine internal transformer winding the degree of change , in turn, can according to the measurement results to determine whether the transformer has been seriously damaged , the need for a major overhaul .
