摘要
主要提出了一种固体绝缘开关柜的基本结构,中压开关柜实现小型化的主要途径是使用介电强度高于空气的绝缘介质代替空气作为主绝缘介质,环氧树脂固化后具有良好的电性能和力学性能,化学稳定性和尺寸稳定性好。分析了国内外40.5kV金属封闭开关设备的小型化技术,确定了采用固体绝缘的小型化方案,对同类开关柜小型化开发具有参考价值。
In the paper, a kind of solid insulation structure for switchgear is described, the main way to realize small structure is to adopt high insulation medium which is higher than air in dielectric strength. Solidified epoxy resin has good electrical and mechanical characteristics, good chemical and dimensions stability. And minimizattion technology of rated voltage of 40.5kV metal- enclosed switchgear is introduced, the proper plan which can be referred to other technical professional is conformed.
