Gaoya dianqi绝缘件的机械和电气性能影响高压开关输配电长期运行的可靠性，降低绝缘件制造过程产生的内应力对提升产品运行质量有关键作用。文中以126 kV盆式绝缘子在固化后降温过程中产生的热应力为分析主体，依据傅里叶定律的传热分析方法，通过对流传热的散热方式，分析盆式绝缘子降温后的热应力分布规律，其应力整体分布均匀，受环氧树脂和金属嵌件热膨胀系数不匹配的影响，在环氧树脂和金属嵌件结合处应力相对较大。对盆式绝缘子采用两种不同降温方式进行冷却，分析应力发生的变化，并通过机械应力检测法验证仿真结果的准确性 ...

Gaoya dianqi高压直流换流阀饱和电抗器在工作过程中发热量大、电场分布不均匀，使其成为阀厅的安全隐患。为改善饱和电抗器的温升效应，文中以实际±500 kV直流换流阀用饱和电抗器为研究对象，建立了改进的流体场与温度场耦合模型，该仿真模型综合考虑流体传热、空气对流散热、绕组焦耳热和铁心涡流热损耗等实际因素，仿真计算电抗器各部件的温度场分布及其影响因素。现场验证表明该模型计算结果更接近实际工作状况。还建立静电场仿真模型，仿真计算电场畸变情况。温度场结果表明：饱和电抗器的铁心温度最高、环氧树脂次之、冷却水管路温度最低 ...
