摘要
本文介绍了油油套管出线变压器铁心剩磁检测原理和接线方式,以一台110kV变压器为应用案例,评估了消磁前后变压器励磁涌流水平,验证了剩磁检测与消磁方法的有效性。
This paper introduced the principle and wiring method of residual magnetism detection for core of oil bushing outlet transformer. Taking a 110 kV transformer as an application case, the inrush current level of transformer before and after demagnetization was evaluated, and the effectiveness of residual magnetism detection and demagnetization method was verified.
