架空线路绝缘水平架空线路绝缘水平trensmission overhead line insulation level力。架空精电线路的绝缘水平是指绝球子的类型及片数、导线对杆塔构架空气间隙、对避雷线间的空气间隙、对地及对各种跨越物最小允许间膝距离的确定。墓本原则及数据在确定线路绝缘水平时，应首先考虑线路所通过地区的气象、环境条件和雷电强度等因素。由于条件不同，额定电压(或最高运行电压)相同的线路，其绝缘水平则会不相同.线路的绝缘水平不仅影响其本身的经济性与运行可靠性，而且决定了可能俊入发电厂、史电所的雷电波。必要时，可在靠近变电所1~Zkm范围内的线路上采用过电压防护措施。由于线路绝缘是自恢复性的，故允许按故障率进行绝缘设计。当降低绝缘水平具有显著经济效益，特别是当操作过电压成为控制因素时，绝缘配合统计法才有价值。在中国，超高压输电线路采用统计法或简化统计法进行绝缘设计，而220 kV及以下电压等级线路采用绝缘配合确定性法(惯用法)进行绝缘设计。对采用常规杆型的一般输电线路(非大功率紧凑型线路)，可只着重研究其相对地的绝缘水平.作用于相对地绝缘上的电压，除长期最高工作电压Up外，还有暂时过电压、操作过电压和雷电过电压，分别用Uo.，、U“.2、U:x3来表明它们的预期值(计算值).不同电压等级的翰电线路的预期暂时过电压U.二.，和预期操作过电压U临2的值如表1所列。裹1不同电压等级抽电艘路的认..，和认，，:值(kV)┌───────┬─────┬─────┬─────┬─────┬──────┐│U。有效值 │35│1 10 │220│330│500 │├───────┼─────┼─────┼─────┼─────┼──────┤│Up有效位 │23.24 │73│146│209。6│317.5│├───────┼─────┼─────┼─────┼─────┼──────┤│U。，，有效值 │40.25(万) │87.64(1.2)│175.3(1.2)│272.5(1.3)│412.75(1.3) │├───────┼─────┼─────┼─────┼─────┼──────┤│认二.2峰位│131.5(4.0)│310(3.0) │619.7(3.0)│652(2.2) │898(2.0)│└───────┴─────┴─────┴─────┴─────┴──────┘注:表中Ue二.，和U.x，2括号内的数字是它们对Up的倍数。外绝缘(绝缘子申、空气间隙)的放电电压U。是指标准气象条件下(气压b。~101.32kPa，温度t。=20℃，绝对湿度119/m，)的试验值，在进行绝缘设计时，绝缘的放电电压U应根据线路通过地区的实际气象条件按下式换算，即U=U。·k，·k:=U。
