Three-dimensional digital expression method for overhead line components based on IFC data format

Abstract

The invention relates to a three-dimensional digital expression method for overhead line components based on an IFC data format. The method comprises the following steps: step 1, according to requirements of an overhead line parameterization design, building a connection relation between the overhead line components based on the IFC data format; step 2, according to the connection relation among the overhead line components, performing three-dimensional parametric modeling and constructing an overhead line through overhead line rapid construction software; step 3, calculating and modifying local details after the overall building, and completing three-dimensional digital expressions of the overhead line components. Compared with the prior art, the method has the advantages that the overhead line designs can be accurately expressed, design results can be quickly visualized, and a data basis is provided for subsequent electrical calculation and analysis.

Description

technical field [0001] The invention relates to the field of overhead line design, in particular to a three-dimensional digital expression method for overhead line components based on IFC data format. Background technique [0002] At present, the design of overhead lines in power grid projects is still mainly based on two-dimensional design. The appearance and size of towers, insulator strings, and fittings in overhead lines are expressed in drawings, and then the connections between these components are expressed in the form of schedules. relationship, such an expression is simple and convenient, and important design parameters can also be clearly presented through the schematic diagram, but because the drawings cannot be linked and there is no reference between the components, based on the analysis of the positional relationship between the various components, such as the calculation of the clearance circle , wire wind deflection, etc., will consume more time, and it will ...
