摘要:
为研究252 kV盆式绝缘子的力学性能,对盆式绝缘子进行重复水压试验和水压破坏试验,利用电阻应变测量技术实测其变形情况。研究发现,重复加载的压力值在3.0 MPa以内,盆式绝缘子的应变变化与受到的外力呈线性,且卸载后盆式绝缘子可恢复到初始状态;根据实测结果分析盆式绝缘子凹面受到压力作用时凸面的应力分布规律,弧线段末端为应力集中区域;盆式绝缘子的应变是外加载荷和内应力的共同作用,内应力过大对盆式绝缘子整体的强度有一定影响。
Abstract:
In order to study the mechanical properties of basin-type insulator, the repeated water pressure test and failure water pressure test on 252 kV basin-type insulator are performed, the deformation of the basin-type insulators is measured based on resistance strain measuring technology. It′s found that when the pressure is under 3.0 MPa, the strain of basin-type insulator is linear with pressure value, and basin-type insulator can restore to its original state when un-loading; it′s also summarized the stress distribution rule of basin-type insulator′s convex surface when its concave surface under pressure, the ends of arc segment is stress maximum area; the strain of basin-type insulator is co-action of applied loads and internal stress, when the internal stress is too large, it will have a certain impact on the overall strength of the basin-type insulator.
