In the light of 500 kV HVAC and HVDC,especially the problems of heavy line-lifting tool and very hugh labour intensity during live replacing the twin suspension insulator strings with single wire clip of straight circuit for heavy load HVDC,a built-up fork hook based on lever principle was developed instead of the taditional process,the double lifting lines.
针对500 kV交、直流输电线路,特别是大荷载直流输电线路直路双联单线夹悬垂绝缘子串的带电更换时,双提线工艺工具沉重,操作劳动强度极大的问题,提出利用杠杆原理研制组合杠杆叉钩卡代替双提线传统工艺,采用单绝缘吊杆挂接组合杠杆叉钩卡组成提线系统,卸去任意一串绝缘子的张力后,另一串绝缘子和提线系统共用承担导线荷载。
补充资料：杠杆
| 杠杆 lever 能够省力的简单机械。当动力作用于动力点时，杠杆即绕其支点转动，而由阻力点实现某种机械效能，如省力、放大等。从杠杆支点到动力作用线和阻力作用线的垂直距离分别称为动力臂和阻力臂。根据杠杆在力矩作用下的平衡条件可知，F·fc＝W·lc，即动力和阻力的大小与它们的力臂成反比。有3种杠杆形式：①支点在动力点与阻力点之间，当动力臂大于阻力臂时可省力，如剪刀；当动力臂小于阻力臂时动力须大于阻力，如用脚操作的碓臼；当两臂相等时两力也相等，如天平。②阻力点在支点与动力点之间，动力臂大于阻力臂可省力，如铡刀。③动力点在支点与阻力点之间，动力臂小于阻力臂，动力须大于阻力，如镊子。 |
