The invention discloses an on-demand dynamic display method for internal details of distribution network plant stations and equipment containers, belongs to the technical field of electric power engineering, and relates to the on-demand dynamic display method for the internal details of plant stations applicable to automatic drawing of power distribution networks and the equipment containers. The on-demand dynamic display method for the internal details of the distribution network plant stations and the equipment containers, provided by the invention, is high in practicality and high in operation convenience, and comprises the following steps: (1) generating primitives A containing the internal details of the distribution network plant stations or the equipment containers; (2) completing line connection between the primitives A of each plant station or each equipment container; (3) generating hidden internal detail primitives B according to the boundaries of the primitives A; (4) determining the display states of the primitives A and the primitives B as required, and performing on-demand dynamic display.
