摘要
详细给出了沿高压输电线路加挂ADSS光缆时电场的空间三维计算原理。为了优化计算,提出了线电荷与点电荷相结合的等效电荷法。在此基础上编制了分析输电线路任意截面及沿ADSS光缆走向的电位、场强分布的三维计算软件。此外,该程序还能考虑转角、换位、舞动等工况。对不同塔型的计算结果表明:软件中采用的算法合理,所得结果对ADSS的挂点选择和优化具有参考价值。
Introduces the method of analysis 3-D electric field around ADSS optical cable set on the power towers. In order to optimize the computation method, the charge simulation method has been developed combined with the equivalent line and point charge.The computation program based on this theory can analyze the potential and intensity of electric field on each section of transmission lines and each position along ADSS. In addition, unordinary load cases are concerned in this software.Numerous computation results show that this method is reasonable and has very good agreement with practical results.
