Abstract (en)

[origin: CA2653677A1] In order to develop a gas-insulated switchpanel of a medium-voltage switc hgear assembly with a busbar connection area (2) and a cable outlet area (3) with a manually actuable switch arrangement (4, 5, 6) with a contact positi on, in which a conductive connection is formed from the busbar connection ar ea (2) to the cable outlet area (3) via the switch arrangement (4, 5, 6) and a vacuum contactor (7), driven by a magnet, and a grounding position, in wh ich the cable outlet area (3) and the vacuum contactor (7) are grounded by t he switch arrangement (4, 5, 6), wherein the vacuum contactor (7) is provide d for switching a current between the busbar connection area (2) and the cab le outlet area (3) in the contact position of the switch arrangement (4, 5, 6), which switchpanel has a relatively high current-carrying capacity, the i nvention proposes that the switch arrangement (4, 5, 6) comprises a groundin g switch (5) and an isolating switch (6), which are mechanically coupled to one another and can be actuated by means of a single drive, wherein, in the contact position, the isolating switch (6) forms the conductive connection a nd, in the grounding position, the grounding switch (5) connects the vacuum contactor (7) and the cable outlet area (3) with a grounding contact (15).</ SDOAB>
