Description
技术领域technical field
本发明涉及电杆倾斜改造,特别是涉及一种电力系统的拉线定位装置及方法。The invention relates to the tilting transformation of electric poles, in particular to a cable positioning device and method for an electric power system.
背景技术Background technique
在电网建设、检修中,由于受地形条件和造价的限制,混凝土电杆的应用仍较为广泛。混凝土电杆自身抗弯能力较差,在电杆架线后会出现受力不平衡现象,采用拉线来平衡各方面的作用力,并抵抗风压,以防止电杆倾倒。In the construction and maintenance of the power grid, due to the constraints of terrain conditions and cost, concrete poles are still widely used. The concrete pole itself has poor bending resistance. After the pole is wired, there will be a force imbalance. The pull wire is used to balance the forces of all aspects and resist the wind pressure to prevent the pole from toppling.
目前国内外装设拉线依靠经纬仪,配合塔尺、皮尺、直角尺、标杆等进行测设。在基层施工、检修中,大部分人员不掌握经纬仪等精密仪器的使用方法,在实际施工中,水泥杆打设拉线往往凭借目测的方式进行,这样的安装虽然在一定程度上可以起到拉线的补强作用,但由于角度方向的偏移,仍会引起电杆的倾斜,甚至断杆等事故。At present, domestic and foreign installations rely on theodolites to measure and set up tower rulers, tapes, squares, and benchmarks. In grass-roots construction and maintenance, most personnel do not master the use of precision instruments such as theodolites. In actual construction, cement poles are often set up by visual inspection. Although such installation can play the role of pulling wires to a certain extent However, due to the deviation of the angle direction, it will still cause the pole to tilt, or even break the pole and other accidents.
因此,需要对一种电力系统的拉线定位装置进行新的研究设计。Therefore, it is necessary to carry out new research and design on a stay wire positioning device of a power system.
