基于三维隔震支座的换流变压器地震响应分析

Gaoya dianqi
换流变压器作为换流站内的核心设备，其水平斜向伸出箱体的阀侧套管受竖向地震作用影响显著。为提高换流变压器的抗震性能，提出由滑动摩擦摆水平隔震系统、弹簧—粘滞阻尼器竖向隔震系统、抗摇摆装置组成的三维隔震支座，并将其应用于±800 kV换流变压器，通过有限元数值模拟，计算并分析了设置隔震支座前后换流变压器的地震响应。结果表明：三维隔震支座显著降低了阀侧套管水平向和竖向加速度响应；相较于水平隔震，设置三维隔震系统的阀侧套管根部应力隔震效率提升了约12%；隔震体系位移响应主要集中在支座 ...

基于IGCT-Plus直流变压器均流问题的研究

Gaoya dianqi
针对双主动桥DC-DC变换器（DAB）的模块化直流变压器，我公司在新型双有源DC-DC拓扑直流变压器进行设计应用，开展了适用于IGCT-Plus作为模组开关器件的直流变压器试验，实现不同电压等级的直流系统的互联，为不同直流负荷提供稳定的直流电压，试验中该直流变压器存在各支路电流长期不平衡流动，会严重影响直流变压器及整个电力系统的长期稳定运行。根据以往工程经验，通过加装均流磁环可对直流变压器低压侧各支路进行均流，均衡三条并联支路的输出特性，防止某一路长期电流应力过大，造成器件老化损坏 ...
