The invention relates to a voltage regulation locking method for a large on-load voltage regulation transformer, and the method comprises the steps: collecting the load current of each side of a main transformer and the power of three sides of the main transformer through a monitoring system, and calculating the load rate of the main transformer; load current and power are collected through the watt-hour meter, and information collected by the monitoring system is verified. By collecting interval accident information of the main transformer, when the main transformer fails, on-load voltage regulation is locked in real time. 本发明涉及一种大型有载调压变压器调压闭锁方法，通过监控系统采集主变各侧负荷电流、主变三侧功率，计算主变负荷率；通过电度表采集负荷电流和功率，对监控系统采集信息进行校验。通过采集主变间隔事故信息，在主变故障时，实时闭锁有载调压。
