Problems solved by technology

If the conventional method is used to find the spatial configuration of the down-conductor, the simulation results will be quite different from the actual spatial attitude of the down-conductor, and it will not be able to provide a realistic simulation for subsequent analysis, which will affect the analysis results

Embodiment Construction

[0039] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0040] A form-finding method for substation down-conductor space, which is carried out according to the following steps:

[0041] Step 1. According to the design requirements, determine the length of the down-conductor and the corresponding mounting positions of the upper and lower hanging points at both ends of the down-conductor in the space;

[0042] Step 2: Fix the stay ropes at the upper and lower hanging points of the down conductor respectively, and connect the tension gauges at the free ends of the fixed stay ropes respectively, and the measuring end of the tension gauge is connected with the corresponding end of the fixed stay ropes. Connect the free end, lift the tension meter, make the down-conductor hang naturally, lift the upper and lower hanging points of the down-conductor to the corresponding mounting positions respectively, and keep the...

Abstract

The invention discloses a transformer substation downlead space shape finding method, which comprises the following steps of firstly, respectively moving two hanging points of a downlead to the hanging positions, keeping the hanging points oriented according to design requirements, and then measuring the pull force of the hanging points along the orientation direction and the orientation angle relative to the horizontal plane; measuring the horizontal span L and the vertical height difference H between the two hanging points; and finally, establishing a corresponding relation between the horizontal span x and the vertical height y of each point on the downlead, calculating to obtain the multi-point data, and fitting according to the multi-point data to obtain the distribution attitude of the downlead in the space. The method has the beneficial effects that the line shape closer to the real condition can be obtained, the method is of great significance for predicting and evaluating thespatial distribution state of the downlead, a simulation result which tends to be real is provided for subsequent analysis and research, and the analysis accuracy is improved.

Description

technical field [0001] The invention relates to a form-finding method for soft conductors, in particular to a method for simulating and analyzing the shape of downconductors. Background technique [0002] The power system is the lifeline project that maintains the lifeline of the national economy. With the development of social economy, various fields rely more and more on electricity. However, the ever-expanding power grid scale, increasing power grid capacity, and gradually increasing geographical span have increased the influence of severe weather conditions on power grid operations and inspections. Under the action of strong wind, wind-induced damage to the down conductor and its connected equipment occurs from time to time. Aiming at the research on the mechanical properties of flexible conductors, Hong et al. simplified the conductors into cables without bending stiffness in 2001, and established the form-finding function (or formula) of the cable conductors under th...
