环氧浇注式绝缘管中间接头处因设计缺陷和安装工艺不良等,绝缘故障频发,严重影响了电网安全稳定运行,通过分析得到引起这类故障多发的原因主要在于中间接头部位爬电比距小、易受潮。基于有限元仿真分析,改进设计了绝缘管母线中间接头,并进行相关电气型式试验。试验结果和现场应用表明:改进后的绝缘管母线中间接头增大了绝缘管母线端部、绝缘筒内壁的爬电比距,提高了防水防潮性能,大大降低了绝缘管母线中间接头部位的故障发生率。

目前,对表面活性剂如何影响诺氟沙星(Norfloxacin,NOR,一种典型的喹诺酮类抗生素)在铁氧化矿物上的吸附行为尚未进行系统的研究。选取十二烷基硫酸钠(SDS)为典型阴离子表面活性剂,探究其对NOR在水铁矿上吸附的影响。结果显示SDS可以促进水铁矿对NOR的吸附,这主要归因于静电引力增强以及SDS的桥联作用。此外,随着pH从5.0增加到9.0,SDS对NOR吸附的促进作用逐渐减弱,这与表面活性剂在水铁矿表面的沉积量有关。此外,当背景电解质为Ca^(2+)时,SDS对NOR吸附的增强作用是由于DS-离子与Ca^(2+)阳离子产生了共沉淀,从而形成NOR-Ca^(2+)-SDS复合物。这项工作表明,广泛存在的表面活性剂对喹诺酮类抗生素的环境归趋具有重要的影响。

In this study, transport behaviors of graphene oxide(GO) in saturated uncoated(i.e., clean sand) and goethite-coated sand porous media were examined as a function of the phosphate. We found that phosphate enhanced the transport of GO over a wide range of solution chemistry(i.e., pH 5.0–9.0 and the presence of 10 mmol/L Na^(+) or 0.5 mmol/L Ca^(2+)). The results were mainly ascribed to the increase of electrostatic repulsion between nanoparticles and porous media. Meanwhile, deposition site competition induced by the retained phosphate was another important mechanism leading to promote GO transport. Interestingly, when the phosphate concentration increased from 0.1 to 1.0 mmol/L, the transportenhancement effect of phosphate in goethite-coated sand was to a much larger extent than that in clean sand. The observations were primarily related to the difference in the total mass of retained phosphate between the iron oxide-coated sand and clean sand columns, which resulted in different degrees of the electrostatic repulsion and competitive effect of phosphate. When the background solution contained 0.5 mmol/L Ca^(2+), phosphate could be bind to sand/goethite-coated sand surface by cation bridging;and consequently, promoted competition between phosphate and nanoparticles for deposition sites, which was an important mechanism for the enhanced effect of phosphate. Moreover, the DLVO theory was applicable to describe GO transport behaviors in porous media in the absence or presence of phosphate. Taken together, these findings highlight the important status and role of phosphate on the transport and fate of colloidal graphene oxide in the subsurface environment.
