Description

Technical Field

[0001] The invention relates to the technical field of electric wire installation, and in particular to a method and system for automatically connecting three-phase electric wires of a 10kV overhead pole tower. Background Art

[0002] In the three-dimensional distribution line expression, the conductor connection of the overhead line is the main component of the distribution line. How to achieve rapid generation of conductors and how to express the correct equipment connection relationship are the key issues to consider in conductor generation. At present, the automatic generation of distribution line tower conductors has been realized. The principle is that each tower sets the offset of the ABC item wiring points relative to the tower coordinates, and then calculates the coordinates of the ABC item wiring points based on the offset, and then connects the wiring points of each item to generate the conductor. However, the conductors generated based on this method are greatly affected by the rotation angle of the equipment. It often happens that the access point and the access point of the same conductor of the tower itself are opposite, or the conductors between the two towers are crossed, which greatly reduces the visualization effect of the three-dimensional distribution line expression.

[0003] In view of this, there is an urgent need for a 10kV overhead tower three-phase electric conductor automatic connection method and system to at least solve the above-mentioned shortcomings. Summary of the invention

The wiring identifiers of each tower on the target line are determined according to the acquired 10kV overhead tower information, and the conductors are automatically connected based on the wiring identifiers. This avoids the situation in which the access point and the access point of the same conductor of the tower itself are opposite or the conductors between the two towers are crossed due to the influence of the rotation angle of the tower when the wiring identifier is directly determined according to the offset when making the connection, thereby greatly improving the visualization effect.
