摘要： In a grounding switch for an encased high-voltage switching system, the movable switching piece is moved by a rotating drive shaft. This drive shaft passes through the housing of the grounding switch. To design the contact elements that transfer the ground potential to the movable switching piece as simply as possible, the drive shaft consists of electrically conductive material. In addition, the drive shaft is insulated as it enters the housing. The drive shaft is also coupled with means to transfer the ground potential, e.g., a current strip, outside the housing. Thus, the drive shaft serves both to transfer force and to transfer potential. A switch blade is designed to be elastically deformable in part, and serves as the movable switching piece. This grounding switch for an encased, compressed-gas-insulated high-voltage switching system can also be used as an insulated grounding switch to carry out measurements.
