進行頂部布線時,請把電源線從線架立桿2中穿線。In view of the rapid development of electric undertaking and a sharp increase of steel products consumption, the state development planning commission, the former state water resources and hydropower ministry and state energy ministry have been urging that the building of steel towers should be strictly controlled in the construction of transformer substations ; and warning that the need of the present 500kv power transmission and transformer trusses can hardly be satisfied by ordinary steel and concrete electric poles or prestressed concrete poles, which have endangered the operation and longevity of the high voltage transmitting line due to the common problem of cracks by gravity
隨著電力工業建設的迅速發展,鋼材的用量急劇增長,為此,國家計委,原水電部和能源部一再強調在輸變電工程建設中,應從嚴掌握自立式鐵塔的建設。然而,一般的鋼筋混凝土電桿或與預應力混凝土電桿,較普遍地存在著縱向裂縫問題,嚴重影響了高壓輸電線路的安全運行及其使用壽命,已不能適應高壓輸電桿塔和變電構架的要求。In this dissertation, the development survey, research actualities and application prospect of vamt are introduced at first, and the models of kinematics, dynamics and linear motor servo are analyzed then. currently the dynamics model is complex or established mechanically, which restricts the study of control theories. thus this dissertation present a simple and easy - realized control idea, namely, the fore and torque of every leg determined by the inverse - solution of mechanics are regarded as changeable load force ( disturbance ) applied in motor, the elongation of the leg or displacement of sliding is regarded as the output of linear servo system
本文首先介紹了虛擬軸機床的發展概況、研究現狀和應用前景,然後對其運動學、動力學、直線伺服系統模型進行分析,針對目前動力學模型過于復雜或完全從機構學角度建立不便於控制的問題,提出了簡單、易於實現的控制思想,即將虛擬軸機床的動力學方程反解所確定的各桿受力(矩)視為電機的可變負載力,以桿長伸縮量或滑塊位移為伺服系統輸出,從此構成位置閉壞,實現軌跡跟蹤控制。Obtained by emtp program and the egm, this paper studies on lightning protection performance on 500kv double circuit transmission line the distributed parameter model of tower is built when analyzing the back stroking lightning protection performance for double circuit line, it can truly reflect the spreading course of lightning current on the tower, furthermore, considering the randomness of working voltage ' s phase when lightning strokes the top tower and supposing the probability of lightning appearing arbitrary phase in a cycle of ac is equal, this paper brings forward the statistical method to calculate the rate of back stroking on double circuit line
本文利用emtp程序、擊距法對500kv同桿雙回線路的耐雷性能進行了研究。在分析同桿雙回線路的反擊耐雷性能時,建立了桿塔的分佈參數計算模型,此模型可以真實地反映雷電流在桿塔上的傳播過程。並針對雷擊塔頂時,導線運行電壓相位角的隨機性,本文假定雷擊出現于交流一周期的任一角度區間內的概率相等,提出了利用統計法計算同桿雙回線路的反擊跳閘率。Hunan electric power line equipment & materials factory was found at 1958, meanwhile belong to hunan electric power bureau, and now is a company of hunan electric power company. the staple are iron tower used under 500kv electric power transmission line and microwave communication, cement pole and electric fitting
