摘　　要：以扼流变压器为研究背景,在深刻了解扼流变压器现场使用情况的基础上,结合现有测试仪器和设备的能力,提出扼流变压器磁化测试电路的新思路,通过电路设计,使扼流变压器的测试方案尽可能的接近其真实的使用状态,在不使用信号线圈辅助测试的情况下,实现单台扼流变压器的磁化测试,使对扼流变压器的磁化测试更加真实、有效。为验证其可行性,搭建测试环境,对扼流变压器的磁化测试电路进行验证。Taking the choke transformer as the research background, this paper puts forward a new idea of the magnetization test circuit of the choke transformer based on the deep understanding of the field application of choke transformer and combined with the ability of existing test instruments and equipment. Through circuit design, the test scheme of choke transformer is as close as possible to the real state of use, and the magnetization test of a single choke transformer is realized without using signal coil to aid the test, which makes the magnetization test of the choke transformer more real and effective. In order to verify its feasibility, a test environment is set up and the magnetization test circuit of the choke transformer is verified.
