摘要:The digitization of power grid projects is a development requirement in the era of big data, as well as an inevitable requirement for the State Grid Corporation of China to build digital power grids and improve life-cycle management. Three-dimensional design establishes three-dimensional models of ground conductors, insulators, and fittings through line electrical majors, and completes line poles and towers in a three-dimensional scene; line structure majors should establish iron tower models and basic models; survey majors should conduct topography and landforms and ground objects to complete three-dimensional scene construction. It can make the circuit design results more intuitive, reduce the drawing work of repeated components, and improve the design efficiency.
