The invention discloses a method for operating a bay level cross measuring and controlling device for sequential control of an intelligent transformer substation, which is used for realizing the operation of the bay level cross measuring and controlling device. The technical scheme of the invention is as follows: operating items on each bay level measuring and controlling device are arranged according to a time sequence for operating primary equipment by an intelligent terminal; data communication and connection among the bay level measuring and controlling devices are established, and the bay level measuring and controlling device previews or executes an operating queue of operation orders. Compared with the prior art, the method has the advantage that a distributed control way in which each bay level measuring and controlling device is used as a core is adopted, the data communication and connection among the bay level measuring and controlling devices are established, and single bay level cross measuring and controlling device operation control and bay cross operation control are realized on the bay level measuring and controlling device, so that a single bay level measuring and controlling device can rapidly, effectively and stably carry out bay cross operation, the advantage of a distribution scheme that the bay level monitoring and controlling device is used as the core can be better exerted, and the on-site operation efficiency is increased.
