Embodiment Construction

[0057] In the prior art, there are still the following problems when establishing the three-dimensional model of the cable down-conductor of overhead transmission lines: (1) the gap between the lead wire and the tower body is controlled by the front side projection distance, which cannot directly reflect the spatial distance, and the calculation results The error is large. (2) Although various 3D modeling software can be used to realize the modeling of some components in the cable down-conductor of overhead transmission lines, 3D layout methods are rarely involved, and the following problems exist in component modeling: (1) cannot Modular design, low efficiency; (2) The results of the 3D design of the cable down-conductor of overhead transmission lines are not intuitive enough; (3) The 3D ground wire model used in structural modeling lacks equipment parameters and design parameters, so it cannot The force calculation and spatial position analysis of the ground wire model can o...

Abstract

A modeling method, module and electronic device for cable lead-down device of overhead transmission line is provided in that embodiment of the present application. The method includes configuring model design parameters according to a to-be-erected overhead power transmission line cable leading device; collecting the basic attribute data, the position data and the GIS geographic data of the electric power equipment included in apparatus, and then establishing a two-dimensional database, a device relational database and a three-dimensional component model database. The modeling rules are set according to the distribution and connection information of electric power equipment, and the three-dimensional model of the device is constructed according to the two-dimensional database, the three-dimensional component model database, the equipment position relational database and the modeling rules. Then collision detection is carried out to adjust the design parameters of the model. The three-dimensional modeling scheme adopts modular design, and combines with the actual situation to configure the model design parameters, its modeling speed is fast, modeling efficiency is high, modeling precision is high and more practical, reducing the enormous waste of manpower brought by the traditional method, high economy.

Description

technical field [0001] The invention relates to the technical field of application of cable down-conductors for overhead transmission lines, in particular to a three-dimensional modeling method, module and electronic equipment for cable down-conductors for overhead transmission lines. Background technique [0002] With urban construction and economic development, overhead cable hybrid lines are becoming more and more common in power grid construction, and it is particularly important whether the cable down-conductors of overhead transmission lines at the connection between overhead lines and cable lines are safe and reliable. In the conventional way of laying out the cable down-conductors of overhead transmission lines, the front view, side view and top view of the cable down-conductors of overhead transmission lines are usually drawn in a two-dimensional plane. At present, the arrangement of down-conductors for overhead transmission lines varies from region to region, mainl...
