摘要 本文提出一种变压器漏抗新的测试方法。用Matlab仿真软件中的Simulink构建变压器漏抗测试仿真模型,并进行仿真分析。分析表明:变压器铁心深度饱和情况下的变压器一次绕组漏抗加二次绕组漏抗之和大于变压器铁心不饱和情况下的变压器一次绕组漏抗加二次绕组漏抗之和。变压器铁心从不饱和到深度饱和,变压器漏抗增加的百分比很小。应用变压器漏抗新的测试方法,可分别求出变压器一次绕组漏抗与二次绕组漏抗。

Abstract:A new test method of transformer leakage reactance is proposed in this paper. A simulation model based on Matlab/Simulink is built and the new test of transformer leakage reactance are simulated. The results show: The sum of transformer primary winding leakage reactance and secondary winding leakage reactance under the condition of transformer core depth saturated is greater than the sum of transformer primary winding leakage reactance and secondary winding leakage reactance under the condition of transformer core is not saturated. Saturated transformer core never saturated to depth, the percentage increase in transformer leakage reactance is very small. Transformer primary winding leakage reactance and secondary winding leakage reactance can be respectively calculated by the new test method.
