摘要
GIS盆式绝缘子的性能直接影响GIS设备的机械受力分布、隔离电源状态及对地绝缘能力。为研究盆式绝缘子缺陷对其力学性能的影响并建立有效评估方法,该文采用循环水压加载模拟实际运行中的电动力作用,对比分析了有缺陷与无缺陷绝缘子在水压作用下的机械响应。研究结果表明,无缺陷盆式绝缘子在承受较小外部载荷时表现出线弹性特性,而缺陷的存在会显著削弱其机械强度。该研究为识别GIS盆式绝缘子结构设计中的薄弱环节及优化其结构提供了新思路。
The performance of basin-type insulators in GIS systems directly affects the mechanical stress distribution,electrical isolation performance,and ground insulation capability of GIS equipment.To investigate the influence of defects on their mechanical behavior and to establish an effective evaluation methodology,this paper applies hydraulic pressure cycling to simulate operational electrostatic forces.A comparative analysis of mechanical responses between defective and defect-free insulators under pressurized conditions was performed.Research findings reveal that pristine basin-type insulators demonstrate linear elastic behavior under minor external loads,whereas defect existence substantially degrades their structural integrity.Furthermore,this study offers novel perspectives for identifying structural weaknesses in GIS basin-type insulators and optimizing their design configurations.
