Dianci bileiqi, 2021 随着全球气候变暖,特大暴雨、雾霾、暴雪等极端天气频发,其中暴雨天气已成为电力设备安全运行的严重隐患之一。空心复合绝缘子已被广泛应用于各种电力设备中,但对于强降雨条件下空心复合绝缘子的冲击闪络特性缺乏系统的研究。以额定电压220 kV空心复合绝缘子为试品,进行了强降雨条件下空心复合绝缘子的冲击放电电压试验,研究结果表明:强降雨条件下,降雨强度对于空心复合绝缘子的50%雷电冲击闪络电压影响不大,而50%操作冲击闪络电压随着降雨强度的增大而减小,符合负幂指数关系;雨水电导率的增加对50 ...

Shuitu Baochi Xuebao, 2004 对皖西南大沙河流域1954～1999年的降水记录和该流域1970年以来的逐月径流和输沙量资料分别进行了趋势分析和关联分析，发现46年来，地处皖西南大别山区的大沙河流域降水的季节和年际变化异常显著，且降水有下降趋势，流域春季、夏季和全年的降水变化率分别为-7．4mm／10a，-13．06mm／10a和-4．6mm／10a。通过对同期降雨、径流和输沙量各因子相互间的灰色关联分析发现大沙河流域输沙量与日雨量大于100mm和50～100mm的暴雨次数关联最密切，其关联系数分别达到0．98和0．90 ...

Shuitu Baochi Xuebao, 2023 喀斯特坡地表层岩溶带发育,入渗强烈,产流机制与非喀斯特坡地有较大差异,为提高喀斯特坡地土壤流失模型预测准确性,以贵州省普定县陈旗小流域6个不同土地利用类型径流小区为观测对象,分析2007-2010年、2015-2019年2期泥沙和地表径流数据,了解产流产沙规律,并利用降雨侵蚀力偏差法计算各小区侵蚀性降雨量。结果表明:(1)植被覆盖率与喀斯特坡地地表产流产沙量呈负相关,高植被覆盖下,暴雨和极端暴雨是造成喀斯特坡地水土流失的主要降雨事件;(2)植被恢复十余年随着覆盖度的提高,年均土壤流失量呈显著下降趋势 ...
