Method for replacing multiple devices to be put into operation at one time of power failure

Abstract

The invention provides a method for replacing a plurality of devices to be put into operation at one time of power failure, which comprises the following steps of: after simultaneously applying for returning a plurality of old devices, removing a related secondary circuit of each old device in an electrified manner; after it is confirmed that the secondary loop and the screen cabinet of each piece of old equipment are both dismounted, corresponding new equipment is installed on an original screen, and single debugging and four-remote joint debugging of each piece of new equipment are completed; in a non-power-off state at each interval, the related secondary circuits are accessed one by one; after all the loops are connected, according to the starting scheme, power-off operation is carried out on all the intervals connected to the new equipment, and centralized transmission is carried out on all the intervals, so that it is ensured that the related secondary loop functions of the new equipment are correct; and after it is detected that all the accessed intervals complete centralized transmission and all the functional loops are not abnormal, all the new devices are applied to be put into operation. By implementing the method, the problems of long time of repeated turn stop after one-by-one transformation of equipment, high risk of a power grid during turn stop, large workload of equipment operation and the like in a traditional method can be solved.
