Line open-phase position determination method and device, equipment and storage medium

The invention discloses a line open-phase position determination method and device, equipment and a storage medium. The method comprises the steps that line switch information sent by line switch equipment in a target line is acquired, and the line switch equipment at least comprises an equipment mutual inductor and a circuit breaker; according to the line switch information, a line fault type corresponding to the target line is determined, and the line fault type comprises an instantaneous fault and a permanent fault; under the condition that the line fault type is an instantaneous fault, determining a mutual inductance alarm signal corresponding to the equipment mutual inductor based on the line switch information; and according to the mutual inductance alarm signal, determining a line open-phase position in the target line, thereby accurately determining an alternating current open-phase position, improving a self-healing success rate of a distribution network, and ensuring normal operation of a power supp
