Dianci bileiqi, 2007 阐述了污秽外绝缘设计的基本方法及存在的一些问题,并在此基础上推荐出了变电站绝缘子污秽外绝缘的设计方法。对于1000kV变电站支柱和空心绝缘子进行污秽外绝缘设计,考虑到现场污秽中所含CaSO4对污耐受电压影响较大,进行了等值附盐密度校正,最后给出了1000kV变电站支柱和空心绝缘子的污秽外绝缘配置,建议Ⅲ级污秽等级1000kV瓷空心绝缘子的结构高度为11.0m～12.8m、支柱绝缘子的结构高度为9.3m～10.5m、复合空心绝缘子的结构高度为8.8m～10.2m。

Dianci bileiqi, 2011 绝缘子故障主要指绝缘电阻劣化和表面污秽。在分析讨论引起绝缘子发热的电阻劣化和表面污秽机理基础上,利用绝缘子等值电路模型分析了绝缘子在电阻劣化和表面污秽时的发热规律以及实际运行绝缘子的热像特征。结果表明:低值、零值和污秽绝缘子的发热规律和热像特征具有明显的差异,故可用高分辨的红外热像仪来检测和分析实际运行中的绝缘子运行状态。

Dianci bileiqi, 2017 快波前冲击过电压对输电线路用盘形悬式瓷绝缘子危害较大,依据标准GB/T20642-2006《高压线路绝缘子空气中冲击击穿试验》,对盘形悬式瓷绝缘子中的空气动力学型瓷绝缘子进行了50%雷电冲击闪络电压和陡波试验,并与钟罩型瓷绝缘子进行了比对研究;研究了瓷绝缘子的形状及大气相对湿度对闪络电压的影响。试验表明:空气动力学型瓷绝缘子50%雷电冲击闪络电压较钟罩型瓷绝缘子低;空气动力学型瓷绝缘子在规定的试验电压下,波前（放电）时间不能满足标准要求;同时,当大气相对湿度较大时,会对瓷绝缘子陡波试验结果产生不利影响。

Theory of Cognitive Relativity Interconstruction and its operational Three-Layer Recursive Architecture [PDF]
This study proposes the Theory of Cognitive Relativity Interconstruction (TCRI) and its operational Three-Layer Recursive Architecture (Root-Stem-Canopy), addressing core epistemological tensions in metacognition [A1,A2,B2]. TCRI posits three fundamental
