摘要
330 k V双回复合杆塔的结构复杂,均压、均场问题突出,为了深入研究其电场分布与均压特性,应用三维有限元分析软件ANSYS,采用程序化静态分析方法和谐响应分析方法,计算了复合杆塔各组成构件承受电压随时间的变化规律,分析了大地、导线等因素对复合杆塔电位分布的影响规律,优化了复合杆塔的横担部分与塔身部分各关键位置的电场分布。研究结果表明:330 k V复合杆塔在原设计的基础上配置合理的均压屏蔽装置能使其电位分布合理,电场分布处于可控范围。
Owing to its complex structure, potential and electric field distributions of 330 k V double-circuit composite tower are extremely uneven. Using three-dimensional finite element analysis software ANSYS, this paper investigated the electric field distribution and voltage-sharing characteristics of 330 k V composite tower. The variation of the time-variable distributed voltage of composite tower was computed. The influences of ground and wires on potential distribution of composite tower were analyzed. The electric field distributions on critical positions were optimized. Based on original design, a final configuration for 330 k V composite tower was determined, in which the grading and shielding devices were configured reasonably. The potential distribution of 330 k V composite tower in final configuration is reasonable and the electric field strength satisfies critical value.
