摘要
通过变压器过电流保护的动作原则,确定变压器各侧过电流保护的动作时限,并根据变压器过电流保护的掉牌情况和断路器动作情况,对变压器过电流保护动作过程和故障点进行了分析。
This document ascertains the time lag of excess current protection's action on transformer's every side through it′s action principle and analyzes the process of excess current protection′s action on transformer and fault point based on the status of lose brand and the action of breaker.
