特高压直流GIL绝缘设计与研究

Gaoya dianqi
高压直流电器随电压等级升高其绝缘结构设计难度显著增大，不能简单地沿用交流绝缘件增大尺寸来处理；否则不仅会增大产品尺寸和成本，在绝缘件运行存在温度梯度时其表面还会积聚大量电荷，使电场分布产生更严重畸变。近年来众多研究企图通过调整绝缘件质量或覆盖表面涂层来改善直流绝缘件电场分布，虽获得一些研究成果，但还不能被产品设计使用。文中强调通过调整绝缘件形状来改善电荷聚集和电场分布的观点，由此提出了结构尺寸小，电场分布好的“椎盘/椎盆”新的直流绝缘件设计，并对其结构和电场作了优化设计计算 ...

温度梯度和电树枝缺陷对高压直流电缆接头电场分布特性的影响

Gaoya dianqi
电缆中间接头结构复杂易出现故障，一旦出现气隙、杂质等微观缺陷，就可能引发电场畸变进而生成电树枝甚至增加击穿风险。并且电缆接头由于空间电荷积聚及温度梯度引发的场强翻转等问题可能引起绝缘击穿。将±200 kV高压直流电缆中间接头设为研究对象，通过有限元仿真软件研究不同温度梯度（ΔT）下生长及滞长阶段电树枝缺陷对电缆接头稳态、暂态电场分布特性的影响。结果表明，当ΔT达到一定值时，SIR和XLPE绝缘内会发生场强翻转；稳态电场下，生长期内电树枝引发的局部电场最大值远高于无缺陷时场强 ...
