    摘要:

    扫频短路阻抗法是检测变压器绕组变形故障的一种新方法,尚处于研究过程中。为解决扫频短路阻抗法研究过程中缺少测试设备的问题,分析了扫频短路阻抗法研究对测试设备功能的要求,采用DDS技术设计了正弦信号发生器,选用APEX集成功率放大器设计了功率放大电路,选用模数转换器AD9225设计了高速采集电路,研制了用于扫频短路阻抗法研究的测试仪样机,并对研制的样机进行了测试,结果表明实现了设计的功能,满足了对变压器绕组测试的需求。

    Abstract:

    The sweep frequency shortcircuit impedance analysis (SFSCIA) is an evolving and novel method for the detection of transformer winding deformations. To provide the testing device for measurement of the sweep frequency shortcircuit impedance, this paper analyzed the functional requirements of testing equipment for sweep frequency shortcircuit impedance analysis. DDS was utilized to design the sinewave generator. APEX integrated power amplifier was used to implement the power amplify circuit. Analog to digital converter AD9225 was adopted to construct the high speed acquisition circuit. The sweep frequency shortcircuit impedance tester prototype was developed. Tests were conducted to verify the performance of the prototype. The test results indicate that the tester prototype achieve the design goal and fulfill the demands of the transformer winding test.
