Problems solved by technology

These drawings are rough, take a long time to draw, and have poor setability
The lack of pre-observed design effects in the connection of transmission line towers and substation construction often leads to design errors, neglect of details, and extension of construction period and other consequences

Embodiment Construction

[0069] Best practice:

[0070] The flexible wire assembly three-dimensional simulation measurement and control system of the present invention mainly conducts innovative research on several important links such as the coordinate measurement of the flexible wire joint, the three-dimensional mathematical model of the flexible wire space, the calculation of the length and sag of the flexible wire, and the three-dimensional assembly simulation model of the flexible wire. . The present invention will be further described by taking the system composition structure described in the summary of the invention as the main line.

[0071] First of all, the space coordinate measurement of the soft wire adopts a non-contact measurement scheme, and a prism-free total station is used to measure by the side-to-side measurement method. The distance measurement signal is a laser, and there is no need to set a prism at the target point to receive the diffusely reflected signal from the object. , ...

Abstract

The invention relates to a technology for measuring and controlling flexible conductors in transformer substation projects, in particular to a three-dimensional simulation, measurement and control system for transformer substation project flexible conductor assembling. The three-dimensional simulation, measurement and control system is a prism-free, total-station-instrument and three-dimensional analog simulation model system and aims at finishing flexible conductor coordinate measurement and computer simulation of the overall three-dimensional space effect and then efficiently and safely finishing on-site conductor installation. An adopted total-station instrument performs contact type measurement, carries on research and verification on a mathematic model of the blanking length of a transformer substation project flexible conductor and designs a conductor three-dimensional space arrangement installation effect picture through a computer. The three-dimensional simulation, measurement and control system has the advantages that the system are used for installation of transformer substation overhead conductors and downleads, and the construction efficiency is improved; the power outage time is shortened and high-altitude construction operation risk is reduced in reconstruction and extension projects; the conductor installing accuracy is improved, and the construction appearance quality is high; a man-machine conversation interface is good, and operation is simple and convenient; the system is good in universality and suitable for various specifications of flexible conductor made of various materials.

Description

technical field [0001] The invention relates to a measurement and control technology for flexible conductors in substation engineering, in particular to a three-dimensional simulation measurement and control system for flexible conductor assembly in substation engineering. Background technique [0002] With the rapid development of substation overhead lines to high voltage and environmental protection requirements, the structure of substations is becoming more and more complex, and electric towers are widely used in the erection of soft conductors. The height of the tower is high, the structural root opening is large, and the slope of the tower is large. The cross-arm in the substation is high and there are many lines, which will bring quality errors, low efficiency and safety hazards to the measurement, erection and construction of soft conductors. [0003] In wire construction, the steps of flexible wire installation include: measurement, calculation, lofting and crimping,...
