混压四回路主要杆塔型式选择与分析

Selection and Analysis of Main Tower type of Mixed Pressure Four Loop

近几年,宁波用电紧张的局面尚未从根本上解决,电网建设的力度在不断加大,建设的电压等级也较多,上至500kV下至35kV,而不同电压等级的线路均需要独立的走廊,相对而言宁波地区的建设用地却日趋紧张,从而导致电网建设路径通道与土地规划之间的矛盾愈演愈烈,为合理的解决这一矛盾而又不影响电网建设的力度,本文提出同塔架设多回路并采用混压架设。

In recent years,Ningbo electricity tensions have not been fundamentally solved,the power grid construction efforts in increasing,construction of the voltage level is more also,from500kV to 35kV,and different voltage lines are needed for independent corridor,relatively speaking Ningbo area of construction land is nervous with each passing day,leading to power grid construction path and land planning between the contradiction intensified,reasonable solution to this contradiction and does not affect the power grid construction,this paper puts forward the same tower erection loop and the use of mixed compression set
