摘要
结合220 kV沪崇苏联网工程,从桥梁变形分析、伸缩缝电缆吸收装置(Offset)的选型、设计原理、结构检算、offset装置设计等方面论述了超高压电缆沿大型市政桥梁需采用的Offset伸缩装置的专题研究,同时根据桥梁的不同情况设计了各种不同型式的offset伸缩装置,为工程顺利进行提供了技术保障。填补了国内无相关offset装置设计技术的空白点。
Based on the 220 kV Shanghai-Chongming Power Grid Connection Project, this paper specializes in the research on Offset （Expansion Joint Absorbing Devices for Cable） applied in EHV cables across large municipal bridges, from the perspectives of bridge deformation analysis, Offset type selection, design principles, structural calculation, Offset design, etc. Meanwhile, different types of Offset devices have been designed in accordance with different bridge conditions, providing technical support for the smooth operation of the project. This research aims to fill in the gap in the domestic field of Offset designing technology.
