新型电力系统下负载因素对三相油浸式变压器振动噪声特性影响的试验研究
Gaoya dianqi, 2022 为了研究新型电力系统下负载因素对S13-M400/10配电变压器振动噪声特性的影响，文中在半消声室中搭建了振动噪声试验平台探究了该变压器的整体模态及其散热片的振动噪声特性，研究了谐波、不平衡负载、过励磁、过载等因素对于该变压器振动噪声特性的影响。研究结果表明，S13-M400/10配电变压器整体模态频谱复杂，固有频率较多；散热片的振动比相邻的油箱箱体部分振动更强烈；三相不平衡负载中不平衡相为B相时振动、噪声小于不平衡相为A相和C相时的振动、噪声；5次谐波下该变压器振动噪声剧增 ...

Functional Ecology, Volume 40, Issue 3, Page 636-654, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Gaoya dianqi, 2021 2018年1月,广州市花都区芙蓉变电站正式投产了国内首台110 kV植物油主变压器。与传统的矿物油变压器不同,该次投运的主变压器采用天然酯作为对流循环散热介质。为掌握此大型植物油变压器的振动特性,文中首先根据变压器振动机理,使用有限元仿真软件建立了植物油介质下的振源振动二维模型,对机械波在植物油中的传播特征进行了研究,之后根据机械波传递特性在变压器的油箱壁高低压两侧分别设置了6个振动测点,采用振动信号分析法对变压器的振动特征进行了研究,为振动监测法在大型植物油变压器故障监测上的运用提供了一定的基础。

China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Gaoya dianqi, 2023 轨道交通运行杂散电流会侵入沿线和牵引变电站中性点，引起变压器直流偏磁运行，导致变压器振动噪声加剧、故障概率增加。为了研究城市轨道交通对变压器振动噪声影响的特性，文中首先理论分析了变压器直流偏磁运行时的振动频谱特性，然后引入一种电量和非电量同步测量的方法，对广州北片区220 kV变电站变压器中性点电流、振动和噪声等物理量进行同步测量，研究轨道交通运行和变电站振动噪声的关系。最后采用数据归一化的方法，获得广州北片区220 kV变压器振动噪声受轨道交通运行影响的一般规律。
