Gaoya dianqi, 2010 串联铁心电抗器实际运行时经常出现故障,给电网运行的稳定性和用电质量造成了一定程度影响。笔者分析了串联铁心电抗器设计中导致产品故障的常见原因,例如绕组烧坏、匝间短路、噪音和温升过高等,同时为防范运行故障的发生,提出了设计中应合理选择电抗率、电密磁密、散热面积,以及重视绝缘结构的设计等具体措施。实践证明这些措施是行之有效的,对串联铁心电抗器的设计、制造和运行维护具有一定的借鉴意义。

Gaoya dianqi, 2017 干式空心电抗器匝间短路是造成其故障的主要原因,而匝间绝缘材料的劣化受温度等因素的影响,因此对干式空心电抗器进行温度场分析有很重要的意义。文中利用Fluent对电抗器正常运行状态以及气道堵塞状态的温度场进行仿真计算,对不同情况下的各包封的温度分布进行分析。结果表明:在正常运行状态下,电抗器内部包封温升明显高于外部包封,同一包封上部温度高于下部,温差大于20 K,热点位于距顶端10%20%处;气道堵塞情况下,阻塞处相邻包封温升明显升高,高出正常运行状况3040 K;气道阻塞对非相邻包封温升影响较小 ...

Gaoya dianqi, 2016 文中以一种新型变压器绕组检测方法——扫频阻抗法为理论依据,建立了试验室测试系统,并利用该系统对单相双绕组变压器进行了测试。其结果表明:扫频阻抗法能够有效反映变压器绕组分布式参数,且其测试结果在频率大于11.5 k Hz时与频响曲线呈现轴对称关系;短路故障会造成50 Hz处阻抗值与相关系数皆发生变化,且故障越严重,阻抗值与相关系数的变化越明显。
