The invention relates to a method for preventing a surge used for an electronic jacquard machine. The electronic jacquard machine consists of a control system and a plurality of electromagnetic needle-selector drive plates controlled by the control system. Each electromagnetic needle-selector drive plate drives a plurality of electromagnetic needle-selector coils. A time-delay unit is connected with the branch circuit, which is connected with the electromagnetic needle-selector drive plate, in sequence, each branch circuit has a different delay time and the delay time of a plurality of branchcircuits forms a time-delay sequence. When the control system needs the electromagnetic needle-selector coil to be electrified, the electromagnetic needle-selector coils connected with the branch circuits are electrified in sequence under the control of the time-delay unit. When the control system needs the electromagnetic needle-selector coil to be powered-down, the electromagnetic needle-selector coils connected with th
