Application and Optimization of 3D Model Reconstruction of Distribution Network Equipment Based on Point Cloud Technology

In recent years, with the increase in the scale of distribution networks, the requirements for their operational safety have become increasingly high, and it is particularly important to conduct three-dimensional (3D) modeling and dynamic maintenance on them. This article focuses on the monitoring of distribution network operation and 3D dynamic operation and maintenance, and conducts research from three aspects: equipment 3D modeling, typical working condition simulation and dynamic operation and maintenance. This article studies the battery shutdown plan and construction site marking, analyzes the data of hidden danger elimination records, and carries out point by point marking of elimination based on the correlation changes of elimination status. Based on the connected environmental disaster information and equipment information, laser scanning is used to collect point clouds of power distribution facilities, and 3D modeling and optimization are performed on them. The transformer scanning time is 15 minutes; the point cloud data volume is 250MB; the reconstruction time is 2.0 hours. Generally, this type of model accuracy evaluation is high-accuracy, and the model integrity evaluation is complete. The scanning time for the switchgear is 10 minutes; the point cloud data volume is 180MB; the reconstruction time is 1.5 hours. This article verifies the accuracy and completeness of this method for equipment 3D modeling through the analysis of laser point cloud data.
