| 摘要: |
| 基于扩展德拜等效电路模型与时域介电响应原理，提出一种能够真实反映绝缘介质响应过程的回复电压函数模型，并利用该函数模型辨识油纸绝缘系统拓扑结构。实验结果验证了所提回复电压函数模型以及油纸绝缘系统拓扑结构辨识方法的可行性与准确性，并且通过等效电路的极化支路条数可初步诊断变压器油纸绝缘老化状态。 |

| Abstract: |
| Based on Debye equivalent circuit model and time-domain dielectric response principle，a return voltage function model of insulation dielectric is proposed to reflect its response process，which is used to identify the topological structure of oil-paper insulation system. The feasibility and correctness of the proposed model and identification method are verified by the experimental results and the aging condition of transformer oil-paper can be preliminarily diagnosed by the number of equivalent polarization branches. |
