【摘要】：复合材料杆塔以其优良的性能及发展前景受到国内外电力部门的密切关注,其长期运行的老化性能成为紧迫的研究内容。为此参考IEC 62217:2005/FDIS推荐的5 000 h多因子老化试验方法,首次进行10 k V复合材料杆塔及电力用复合材料样品的5 000 h多因子老化试验。建立10 k V复合材料杆塔制品的三维模型,采用有限元法对多因子老化室内杆塔各个部件的电位和电场分布进行了仿真,仿真结果与杆塔不同部位在试验结束后表现出的老化性能存在相关性。对进行老化试验后的电力用复合材料样品的弯曲模量和弯曲强度进行测试,测试结果表明大部分样品弯曲模量保留率都在90%以上,耐老化性能良好。综合考虑弯曲模量、弯曲模量保留率和弯曲强度,最终确定复合材料杆塔生产使用改性聚氨酯PU/1:1方格布材料和拉挤工艺。
[Abstract]:The composite tower has been paid close attention to by domestic and foreign power departments for its excellent properties and development prospects, and its long-term aging performance has become an urgent research content. For this reason, referring to the 5 000 h multi-factor aging test method recommended by IEC 62217: 2005 / FDIS, For the first time, the multi-factor aging tests of 10kV composite tower and power composite material samples were carried out for the first time. A three-dimensional model of 10kV composite tower products was established. The potential and electric field distribution of various parts of the tower are simulated by finite element method. The simulation results are related to the aging properties of different parts of the tower after the test. The flexural modulus and bending strength of the composite materials after the aging test are tested. The results show that the retention rate of bending modulus of most samples is more than 90%, and the aging resistance is good. Finally, the use of modified polyurethane PU/1:1 lattice cloth and pultrusion process was determined in the production of composite tower.
