电气化铁道半导体釉绝缘子运行情况初步调查 附视频

Dianci bileiqi, 1976
对电气化铁道半导体釉绝缘子的运行情况调查结果表明,X-4.5及TX-25A两种半导体釉悬式绝缘子已分别在线路上运行了15个月和10个月,均未清扫过,但没有发生过污闪事故。并拆下5串自然污秽绝缘子进行了污秽及污耐压测量。从试品的污秽程度来看均属三级污秽地区,所有试品均通过36千伏污耐压试验,半导体釉绝缘子的污闪电压均在60千伏以上,普通釉的污闪电压只有40.7千伏。泄漏电流的现场实测表明,脏污绝缘子泄漏电流很小。模拟蒸气机车喷气时绝缘子工况实测结果为,喷气2分钟后,其泄漏电流达13毫安,但下降很快 ...

基于氟硅橡胶的超憎水高耐候性防污闪涂料的制备与性能研究

中国科学与技术学报
本研究在借鉴高温硫化氟硅橡胶制备工艺和复合绝缘子表面处理技术的基础上，通过氟化占位定向技术、超分子合金化与原位聚合法精细调控硅橡胶主链结构，并引入功能化石墨烯及多种有机／无机填料，成功合成了一种新型超憎水、防污闪、耐候性优异的复合涂料。配方中合理优化氧化镁、氢氧化铝、铁氧体、异丙基氨基甲基丙烯酸酯、含氟酯类、嵌段硅氧烷、膨胀石墨及阻燃助剂等组分比例，使涂层在标准实验室条件下初始静态接触角可达113°以上，喷水分级达HC1级。在连续水浸96 h、192 h及360 h等加速老化试验后，涂层仍能保持θav ...
