高压交流架空输电线路下工频电场强度模式预测与实测对比研究

通过实际测量、理论计算,并分析理论计算方法的可靠性和局限性,根据工频电场很容易被屏蔽的原理,对八昆220 kV/八蓝110 k V同塔四回线路和京酒220 kV/东金110 kV同塔四回线路修正后的工频电场强度理论计算值和实际测量值进行对比,考虑屏蔽作用的理论计算值更接近实际测量值。

Through the actual measurement,theoretical calculation,and analysis of the reliability and limitations of the theoretical calculation method,according to the principle of the power-frequency electric field is very easy to be shielded,to nBa Kun220kY/Ba Lan llOkV Erection of the same tower”and “Jing Jiu220kv/Dong Jin llOkV Erection of the same towern,the calculated value and the actual measured value of the modified power-frequency electric field strength are compared,and the theoretical calculation values considering the shielding effect are close to the actual measured values.
