The invention provides a power emergency maintenance work order overtime processing system and processing method, which are used to prompt workers to process line faults indicated by an emergency maintenance work order in time. The system comprises a base, a telescoping rod, a box, a swallowing assembly, a storing assembly, and a timing assembly. The box is arranged above the base and is connectedto the base through the telescoping rod. The swallowing assembly, the storing assembly, and the timing assembly are arranged in the inner side of the box. The swallowing assembly comprises a work order swallowing unit for swallowing work orders and a transferring unit for delivering and transferring work orders. The storing assembly comprises an upper fixed seat and a lower fixed seat, which arerotatingly arranged in the box; a swinging mechanism, which drives the upper fixed seat and the lower fixed seat to rotate synchronously; a first screw rod, which is arranged between the upper fixed seat and the lower fixed seat; an elevating screw nut, which is arranged on the first screw rod; a work order support, which is fixedly connected to the elevating screw nut; and an elevating motor, which drives the first screw rod to rotate. The timing assembly calculates the processing time. The provided system and method can effectively realize work order storage and monitor the processing time.
