Column box type high-voltage switch

The invention provides a column box type high-voltage switch which comprises an upper column shell, a lower box shell and a middle fixing plate which are made of insulating materials, a high-voltage access assembly is arranged in the upper column shell, a low-voltage control assembly is arranged in the lower box shell, and the middle fixing plate is used for fixing the upper column shell and the lower box shell; the column box type high-voltage switch combines the advantages of an existing column type high-voltage switch and an existing box type high-voltage switch, and is small in size and easy to automatically assemble; the upper column shell and the lower box shell achieve effective isolation of high voltage and low voltage, and all components in the upper column shell are insulated from one another. Meanwhile, a space is reserved in the upper cylindrical shell, so that installation of various sensors is facilitated. 本发明提供了一种柱箱式高压开关，包括由绝缘材料制备而成的上柱壳、下箱壳和中间固定板，所述的上柱壳内设置有高压通路组件，所述的下箱壳内设置有低压控制组件，所述的中间固定板用于实现上柱
