The invention discloses a safety anti-misoperation and sound-light alarm integrated logic system applied to a voltage paralleling device. The safety anti-misoperation and sound-light integrated logic system comprises a three-phase voltage unbalance out-of-limit criterion module, a voltage vector comparison module, an edge-triggered logic setting module and a sound-light integrated alarm module. The integrated logic system provides a safety anti-misoperation function and a field sound-light integrated safety warning for a voltage paralleling/splitting field operation and maintenance, thereby effectively eliminating a voltage paralleling/splitting misoperation event; and meanwhile, corresponding logic is integrated into a substation integrated diagnosis system, so that a function that an operating background and a monitoring center monitor alarm information in real time can be realized.
