特高压直流线路带电融冰系统研制及工程应用

Gaoya dianqi
为避免覆冰引起线路跳闸事故，且在融冰时不影响线路运行，论文研发了特高压线路地线和光纤复合架空地线（OPGW）的带电融冰系统，包含融冰电源、融冰装置、过电压保护系统、OPGW与地线回路。开展了OPGW/地线融冰参数校核、融冰装置参数校核，换流变压器、平波电抗器、桥臂过电压保护器选型，融冰线路绝缘化改造和绝缘配合设计，研发了特高压线路OPGW带电融冰系统。现场实测表明，融冰回路双端开路时，OPGW/地线感应电压可达13.7 kV，融冰回路单端接地时，感应电压降低至0.6 kV。计算表明 ...

轴向荷载作用下小规格拉铆钉和普通螺栓疲劳性能对比研究

Jianzhu Gangjiegou Jinzhan
拉铆钉因其良好的防松动、抗疲劳和防腐性能以及较强的环境适应性等特点而被广泛应用于航空航天、轨道交通、桥梁建筑等领域。为解决光伏支架中螺栓连接易发生疲劳的问题，现研究一种国产新型拉铆钉的轴向疲劳性能，用以代替普通螺栓连接进而提高光伏支架的疲劳寿命。对LMY8和LMY10小规格拉铆钉及同规格的普通螺栓进行了轴向荷载作用下的静力试验和疲劳试验，并利用ABAQUS软件进行了拉铆钉铆接过程的模拟，利用FE-Safe软件对拉铆钉疲劳寿命进行了模拟。研究结果表明：在同样条件下，铆钉的疲劳性能优于普通螺栓的疲劳性能 ...
