摘要:
为有效抑制特高压输电线路舞动,保障电网安全稳定运行,针对特高压输电线路的建设特点及舞动特性,结合现有各电压等级输电线路舞动情况,研制了一种新型防舞装置——相地间隔防舞装置。该装置以复合绝缘子为主体,配以拉线,一端连接输电线路,一端连接地锚,以大地为强制约束点,通过施加一定预紧力,并合理布置安装位置、拉力方向等,可实现对舞动的有效抑制作用。通过对2014-07-21~2015-03-31时间段发生的舞动事件宏观统计分析,并基于绝缘子动张力数据对2015-01-19日发生的一次舞动事件进行分析,结果表明,合理安装相地间隔防舞装置后可有效减少舞动发生频率,能够有效减少线路舞动对绝缘子的冲击和疲劳损伤,绝缘子可靠性提升96.82%。
Abstract:
A new anti-galloping device(phase-to-earth anti-galloping device)was developed to inhibit UHV transmission line galloping and safeguard grid’s safety and stable operation based on transmission line galloping characteristic. This device consists of composite insulators and wire. One side was linked to transmission line, the other one was linked to earth, the effective restraining galloping can be achieved by applying a certain pre tightening force, and arranging the location and the direction of the tension reasonably, taking the earth as the mandatory constraint point. The galloping events(2014.7.21~2015.3.31) were analyzed by statistical methods, and the tension of insulator was analyzed in detail in the galloping event(2015.1.19). Some conclusions were drawn that, after a reasonable installation of a phase-earth anti-galloping device, the impulse and fatigue damage of insulators and the frequency of galloping was reduced and the reliability of insulator was enhanced 96.82%.
