Summary:The invention relates to a surge prevention method for a multi-load control system. Delay units are connected to loaded branch circuits, the delay times of the branch circuits are all different and the delay times of the branch circuits make a delay sequence; when the control system wants the loads to be galvanized, the loads will be galvanized sequentially under the control of the delay units, while when the control system wants the loads to be powered down, the loads will be powered down sequentially under the control of the delay units, thus avoiding surge current and surge voltage when the loads are galvanized or powered down at the same time. Compared with the response speed of the loads required by the system, the total delay time of the delay sequence is small, thus not affecting the normal work of the loads.
