The approach to using power electronic switching instead of traditional mechanical switches to remove damping resistance is discussed mainly. The paper focuses on prolonging of the transient transition process caused by rapid removing action and the inherited transient process caused by the non-zero-crossing synchronization trigger. Firstly，the rapid switching circuit and its existing problems are introduced，after which we analyze the mechanism of influence on residual current and residual time caused by the action，and describe the influencing process in detail. Secondly，by using Simulink software，the model of the damping resistance switching circuit is established which is applied to the 10.5 kV voltage class. Simulation and analysis of the influence are carried out for the typical fault situation and different trigger condition of bidirectional thyristor. The influence is proven by test using the platform of the cooperative company. Finally，the solution of delaying removing and triggering with zero-crossing is proposed and verified
