摘要 10 kV固体绝缘真空断路器近年来在配电网中广泛应用。为了研究其环氧树脂外绝缘体的沿面、空间工作场强以及金属屏蔽层对固封极柱电场强度的影响, 根据外绝缘体实际尺寸参数, 采用Solidworks软件建立了三维仿真模型。并针对客户提出的固封极柱外屏蔽接地可触摸的要求, 建立镀铝层固封极柱的简化仿真模型, 采用Ansoft Maxwell 3D仿真软件分别对外绝缘体和固封极柱进行仿真计算。结果表明: 现有外绝缘体的工作场强距最高标准尚有较大裕度; 镀铝屏蔽层的安装会增大固封极柱的工作场强; 若环氧树脂固封极柱中有气泡, 则镀铝层的安装可能加剧固封极柱的局部放电。

Abstract:10 kV solid insulation vacuum circuit breakers are widely used in electrical distribution networks. The effects of the space between the insulator and the metal cover and the cover itself on the electric field intensity around the outer insulator were analyzed for a solid sealed pole. Realistic 3-D simulation models were built in Solidworks. A simplified model of an aluminum solid sealed pole was set up with the external shielding grounded. The electric field intensity was predicted using Ansoft Maxwell 3D. The results indicate that the electric field intensity around the outer insulator has a large range. A metal shield increases the electric field intensity of the solid sealed pole. If there are some bubbles in the solid epoxy sealed pole, the metal shield may aggravate the partial discharges.
