| 摘要 |
The invention provides for a medium voltage switchgear connectable to an electrical cable (6), comprising an enclosure (7) provided with a opening (3) for introducing a test electrode (24) into the enclosure (7), a cable test contact (25) which is located inside of the enclosure (7), wherein the cable test contact (25) is electrically connectable with the cable (6), and earthing means (26) for earthing the cable test contact (25) in an earthed position of the switchgear, wherein the earthing means (26) are removable from the earthed position into a test position of the switchgear in which the cable test contact (25) is disconnected from earth (32), wherein the earthing means (26) comprise a movable earthing element (26) which extends between the cable test contact (25) and the opening (3) in the enclosure (7), and wherein the earthing element (26) is hollow for receiving the test electrode (24). |
