Abstract

A three position switch of a high pressure gas-insulated switchgear device is controlled by an operating mechanism and a drive main shaft for three working states: insulated switch switched on, insulated/grounding switch switched off and grounding switch switched on. The insulated switch and the grounding switch share a moving contact shell. The rotating shaft which is fixed on the moving contact shell through a bearing connection is connected with the operating mechanism of the three position switch through the insulating shaft. The other side of the rotating shaft is connected with an inner connecting lever which is respectively hinged to the moving contacts of the insulated switch and the grounding switch through two insulating connecting rods. Driven by the operating mechanism, the cylindrical moving contacts of the insulated switch and the grounding switch can smoothly slide inside the guiding chamber of the moving contact shell and respectively perform three position operation of insulated switch switched on, insulated/grounding switches switched off and grounding switch switched on. The utility model, by controlling the insulated switch moving contact and the grounding switch moving contact through the same operating mechanism and drive main shaft, is structurally realized an interlocking between the insulated switch and the grounding switch, which makes the switchgear safe and reliable in operating process. The three position switch is a novel switch which has the characteristics of exquisite structure, great carrying capacity and safe reliable operation.
