The invention belongs to the technical field of distribution network automation, and particularly relates to a distribution network loop closing and opening operation early warning method, which comprises the following steps of: acquiring a loop closing line and a loop opening line which need to be subjected to loop closing and opening operation; acquiring loop closing line data of a loop closing line, loop opening line data of a loop opening line, and power flow data of the loop closing line and the loop opening line before and after loop closing and loop opening operation; according to the line data, whether a preset loop closing and opening early warning strategy is met is judged, and when the line data meets the loop closing and opening early warning strategy, early warning is carried out and/or a tripping plan is generated; whether the power flow data of the loop closing line and the loop opening line before and after the loop closing and opening operation is abnormal is judged, and when the power flow d
