摘要： An earthing switch may be used for a metal-clad, high-voltage switchgear insulated with compressed gas. The mobile earthing contact is arranged so as to be insulated from the earthed cladding for measuring purposes. The insulation arrangement of the earthing contact is bypassed by an electrical connection, preferably outside of the cladding to earth the switching device. The electrical connection is disconnected when the earthing contact is connected in the closed position to a measuring device. An additional contact arrangement is provided that electrically bypasses the insulation arrangement and connects the mobile earthing contact to the earthed cladding when the switch is between the closed and open positions. This prevents surges resulting from pre-arcing on the insulation arrangement and possible damage to measuring instruments that may be connected to the earthing switches.

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.
