Cell medium voltage gas-insulated and high dielectric strength.

摘要

A CELL ELECTRIC MEDIUM VOLTAGE, PARTICULARLY OUTPUT AND PROTECTION OF A TRANSFORMER (12), comprising a switch (14) previously connected to busbars (16) via a switch (18) above, and then to a shorted FUSE (20) PROTECTION output circuit. TO IMPROVE THE BEHAVIOR DIELECTRICO the cell MEDIA GROUND CIRCUIT output comprises a switch (24) BACK CONNECTED IN PARALLEL TO THE TERMINALS OF THE BREAKER WITH FUSE (20) and a connection contact (36) to ground (21) cooperating, WELL WITH MOBILE CONTACT PREVIOUS SWITCH (18) with three positions, or with a disconnector ABOVE GROUND TO MAKE THE GROUND output circuit through the switch (14) when the latter is SWITCHED in the closed state.
