摘要
从理论计算和真型试验两方面着手,对复合材料电杆在配网转角杆中的应用技术进行了深入研究。采用有限元软件和参数化编程,考虑P-δ效应,详细计算了无拉线转角复合材料电杆在各个工况下的应力和杆顶挠度。计算结果显示,复合材料电杆的强度和挠度均满足规范要求,但是挠度比水泥杆挠度大很多。采用有限元软件,详细计算了12 m单回、15 m单回和15 m双回拉线转角复合材料电杆在大风工况下的应力、杆顶挠度和结构稳定性,结果均满足使用要求。为验证复合材料电杆在下压力作用下的稳定性,对上述三种复合材料电杆进行了力学真型试验。在超载至140%的情况下,电杆整体仍未见异常。试验结果为实际工程应用提供了一定依据。
The application technology of composite pole in distribution network angle ploe has been studied from theory calculation and true test.By using finite element software and parameterized programming,considering the P-δeffect,the stress and the top deflection of angle composite pole without guyed under various working conditions have been calculated in detail.The results show that the strength and deflection of the composite pole meet the requirements of the code,but the deflection is much larger than that of the concrete pole.The stress,deflection and structural stability of 12 m single circuit,15 m single circuit,and 15 m double circuit angle composite poles with guyed under the condition of maximum wind speed have been calculated in detail,and the results meet the requirements of use.In order to verify the stability of the composite pole under the pressure,the mechanical true tests of the above-mentioned three kinds of composite poles have been carried out.In the case of overloading to 140%,there is no abnormal phenomenon on the whole pole,which provides a basis for practical engineering applications.
