天生桥换流站直流滤波电容器近年来频繁损坏的原因分析及改造措施
Gaoya dianqi, 2010 根据天生桥换流站直流滤波电容器近年来频繁损坏的情况,通过对故障直流滤波电容器的解剖,深入分析了直流滤波电容器近年来频繁损坏的原因。提出了两种改造措施:一是用单只或几只国产电容器与原进口电容器搭配使用的方案;二是对现有的直流滤波电容器进行整组改造。第1种方案从成本和经济实用性来讲优于第2种方案,并且已经在天生桥换流站成功应用。长期以来直流滤波电容器一直依赖于进口产品,笔者依托于天生桥换流站,用单只或几只国产电容器与进口电容器搭配使用是一种新的尝试,解决了进口直流滤波电容器无替换品的难题 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Phase‐change memory (PCM), characterized by its reversible transition between crystalline and amorphous phases, has emerged as a promising candidate for neuromorphic memory computing applications. However, conventional PCM devices lack an insufficient RESET/SET voltage ratio, which often leads to incorrect recording of the RESET state and ...

Gaoya dianqi, 2009 并联电容器组是交流电力系统输配电环节的主要无功补偿装置,在变电站中普遍采用10 kV框架式高压并联电力电容器组。实际运行中,电容器内部元件击穿的故障是电容器组故障比例最高的。以常用的10 kV并联电容器为研究对象,分析了电容器组在运行过程中内部元件击穿一串、二串情况的击穿放电量,故障相电容器的电压暂态变化量,并估计了放电电流的峰值。在EMTP仿真软件中建立了电容器的击穿模型,计算并分析了击穿元件的等效电路参数对放电电流峰值的影响:电阻值越大,则击穿峰值电流越小,随着电阻值的增加,击穿电流峰值下降减缓 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Low conductivity, slow ion‐diffusion, and limited reactive sites are common problems in electrocatalysts and electrode materials. In this study, a complex NiTe–CoTe heterojunction with abundant Te vacancies embedded in N, P, and F co‐doped hollow carbon nanorods (NiTe1−x–CoTe1−x/NPFC) was fabricated via a simple ionic liquid‐assisted ...

Gaoya dianqi, 2018 标准电容器具有优良的电压系数和温度系数、介质损耗极小、电容量稳定等优良特性,被广泛的应用于高电压测量中作为参考标准或测量分压器的高压臂。平行平板电容器作为高压标准电容器的一种新型结构具有结构简单、可带有板蔽电极等特点;但其电位分布不均匀是其一个较大的缺点,容易造成绝缘筒沿面闪络,发生绝缘击穿事故。文中以1 200 kV平板电极标准电容分压器为例建立了高压标准电容分压器的计算模型,计算得到了高压标准电容分压器绝缘筒外部电位随高度的变化曲线,通过在电容分压器内部增加多层金属板 ...
