Hydraulic-damping-utilizing power transmission tower capable of preventing torsion of main tower
The invention discloses a hydraulic-damping-utilizing power transmission tower capable of preventing torsion of a main tower. The power transmission tower comprises a main tower, a low-hanging-point rotating arm, a sliding bracket, a low-hanging-point insulator, a high-hanging-point insulator and a torsional hydraulic damper. Acting force in the horizontal direction and torsional force caused by the low-hanging-point rotating arm in accident conditions are unloaded via rotation of the low-hanging-point rotating arm; the torsional hydraulic damper is used for reducing line breakage impact and structural vibration; in the accident conditions, unloading operation can be carried out more slowly and effectively; meanwhile, the sliding bracket capable of moving in a horizontal sliding groove inthe low-hanging-point rotating arm is arranged, so in case of low hanging point erection of a power transmission line, the moment of torsional force of the power transmission line to the main tower can be reduced according to actual working conditions and the torsional force of the main tower is lowered; and after the low-hanging-point rotating arm rotates, the arm of force in the horizontal direction is greatly reduced, the torsion speed and the vibration frequency of the low-hanging-point rotating arm are limited, so the torsion and the vibration borne by the main tower are greatly reduced and therefore the effect of protecting the main tower is achieved.
本发明公开了一种利用液压阻尼的防主塔扭力的输电塔，包括主塔、低挂点旋转臂、滑动支架、低挂点绝缘体、高挂点绝缘体和扭转液压阻尼器，利用低挂点旋转臂的旋转来卸载事故工况中水平方向的作用力与低挂点旋转臂引起的扭转力，并利用扭转液压阻尼器来减小断线冲击和结构振动，在事故工况中，能够更加缓慢、有效的进行卸载操作，同时设置可在低挂点旋转臂内的水平滑槽中活动的滑动支架，使输电线的低挂点架设时，能够根据实际工况降低输电线对主塔的扭转力矩，从而降低对主塔的扭转力，在低挂点旋转臂旋转后，使水平方向的力臂大大减小，并限制低挂点旋转臂的扭转速度和振动频率，使主塔所受到的扭力和振动大大减小，从而起到保护主塔的作用。
