The invention discloses a three-dimensional model file of a physical loop model and a configuration method. The method comprises a 3D model, a file hierarchy and an object attribute. The 3D model is composed of a screen cabinet, 4U whole-layer equipment, 4U half-layer equipment, switch equipment, first-layer ODF equipment and a normal board card, the hard pressing plate expands corresponding elements under screen cabinet elements, meanwhile, the requirement for three-dimensional panoramic display is considered, and space coordinates of all objects and object model reference attributes are increased; the file hierarchy is of a tree structure, and basic information, coordinates and model information of a file hierarchy object are input into a Substation three-dimensional model file, so thatconfiguration logic is set to be of the tree structure; the object attribute is composed of a transformer substation, an area, a physical cable, a screen cabinet, an equipment element, a hard pressingplate, a pressing plate element, a terminal strip, a terminal number, an in-cabinet fiber core and a cable fiber core; a physical object interface and a three-dimensional model interaction interfaceare expanded through a physical loop file, and the problem of data interaction between a physical object and a three-dimensional model is solved.
