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 ...

Dianci bileiqi, 1985 随着高压技术的发展,电力陶瓷电容器的应用日益广泛。在经常反复的陡波头冲击下或在高频振荡的振荡冲击下工作的贮能器和脉冲发生装置中使用了陶瓷电容器。在高压断路器的分压器中也使用了电力陶瓷电容器。高压陶瓷电容器通常分高频和低频两种。为在工频高压装置内和周期重复冲击下工作,除用由介电常数不超过150的传统高频材料制造的电容器以外,还采用由介电常数为900及以上的陶瓷制造的电容器,其单位特性较高。英国Plessey公司生产的圆板形电力陶瓷电容器由介电常数为150的材料制造 ...

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 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Two‐dimensional (2D) nonlayered niobium nitrides have attracted considerable interest for electrochemical energy storage. However, the synthesis of these materials is hampered by their nonlayered crystal structures, which are characterized by strong three‐dimensional chemical bonding.

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 ...
