摘　　要：本文中作者为解决高压绕组内置型高阻抗变压器空投过程中遇到的一些问题,采用基于分闸时的剩磁与合闸时的偏磁相互抵消原理的涌流抑制器对变压器的断路器进行了改造。In this paper, in order to solve some problems encountered in the air-dropping process of high-voltage winding built-in high-impedance transformers, the inrush current suppressor based on the principle of mutual reversal of residual magnetism and closing when closing is used to circuit the circuit breaker of the transformer.

关 键 词：变压器 高压绕组 高阻抗 励磁涌流
