摘要
迄今为止,我国设计、建设的500kV紧凑型输电线路都采用了倒等边三角形的布置方式,对于海拔1000m以下地区线间距离大都为6.7m,除早期的紧凑型线路采用6×240mm2导线外,多数采用6×300mm2导线。本文在原来500kV紧凑型输电线路设计经验的基础上,对导线布置方式、相导线分裂方式、直线小转角塔的设计等进行了分析,对今后的500kV紧凑型输电线路设计进行了探讨。
The inverted-delta conductor configuration mode has been adopted in the current 500kV compact transmission line in China. In those areas that the altitude is below 1000m, the phase-phase distance is 6. 7m. Except for the early compact transmission line in which 6 - 240mm^2 conductor was adopted, 6 - 300mm^2 conductor line is adopted in most compact transmission line. Based on previous design experiences of 500kV compact transmission line, the conductor line configuration, phase conductor spacing mode, design of small angle tower are analyzed in this paper, and the future trends of compact transmission line design are also discussed.
