摘要

阻尼隔离杆是超高压输电线路中关键的保护装置,它不仅能保持分线之间的距离,限制分线之间相对运动造成的鞭打和碰撞,还能抑制导线的振动。针对超高压输电线路在长期运行过程中,阻尼隔离棒容易出现线夹松动等典型故障,进行了研究。以FGZ-450/34B型隔杆为对象,探索了隔杆架高压铸造新工艺。采用ABAQUS有限元软件对隔震杆进行了数值模拟,预测了隔震杆的应力分布,识别了隔震杆的危险部位。在此基础上,对模具工艺进行了优化,避免了压铸缺陷。同时,对两种模具生产的产品进行了力学性能测试。研究发现,通过优化模具工艺,可以有效提高隔杆危险部位的压铸质量,并通过对比得出最佳高压压铸方案。本研究成果为提高阻尼隔离杆的抗振动性能、抗松动可靠性、抗短路电流热冲击性能和抗紫外线老化性能提供了技术支持。对保证特高压输电线路的稳定运行,提高阻尼隔离棒的生产工艺水平具有重要意义。

A damping spacer rod is a key protective device in ultrahigh voltage transmission lines, which not only keeps the distance of split wires and limits the whipping and collision caused by the relative motion between sub-wires, but also inhibits the vibration of wires. This study aims to solve the problem of typical faults, such as loose wire clamps, that are prone to occur in damping isolation rods during long-term operation in ultra-high voltage transmission lines. Taking the spacer rod FGZ-450/34B as the object, a new high-pressure casting process for spacer rod frames is explored. The spacer rods were simulated by using the ABAQUS finite element software to predict the stress distribution and identify the dangerous sections. Based on this, the mold process was optimized to avoid die-casting defects. Meanwhile, mechanical property tests were carried out on the products produced by the two types of molds. The research finds that by optimizing the mold process, the die-casting quality of the dangerous section of the spacer rod can be effectively improved, and the best high-pressure die-casting scheme has been obtained through comparison. This research achievement provides technical support for enhancing the anti-vibration performance, anti-loosening reliability, short-circuit current thermal shock resistance, and anti-ultraviolet aging performance of damping isolation rods. It is of great significance for ensuring the stable operation of ultra-high voltage transmission lines and improving the production process level of damping isolation rods.

期刊介绍: Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
