摘要： A switching apparatus for medium voltage electric systems, said switching apparatus comprising one or more electric poles and, for each electric pole:
- a first pole terminal, a second pole terminal and a ground terminal, said first pole terminal being electrically couplable with a first conductor of an electric line, said second pole terminal being electrically couplable to a second conductor of said electric line and said ground terminal being electrically couplable to a grounding conductor;
- a fixed contact assembly including a plurality of fixed contact members spaced one from another;
- a movable contact assembly rotatable about a rotation axis between a first end-of-run position (PA), which corresponds to a closed state of said switching apparatus, and a second end-of-run position (Pc), which corresponds to a earthed state of said switching apparatus, said movable contact assembly passing through an intermediate position (P B ), which corresponds to an open state of said switching apparatus, when moving between said first and second end-of-run positions.
The movable contact assembly is arranged so that, when the switching apparatus is in an open state, the electric contacts within a vacuum chamber of the movable contact assembly are mutually coupled.

摘要： The present invention relates to an earthing switch (1) for a medium voltage switchgear wherein said earthing switch comprises a frame (5) supporting a mechanism (4) for rotating a plurality of moving contacts (2) between a first reference position and a second reference position. Said mechanism comprises a first shaft (11) on which the moving contacts (2) are rigidly mounted, said first shaft (11) rotating around a longitudinal axis (101) in a closing direction (W1) for which said moving contacts (2) reach said second reference position and in an opening direction (W2) for which said moving contacts (2) reach said first reference position. According to the invention, the mechanism comprises also a second shaft (12) coaxial to said first shaft (11) and connectable to an operating mechanism for the control of said second shaft (12). The mechanism further comprises first coupling means (15A, 15B) of said shafts (11,12) configured so that said second shaft (12) is free to rotate with respect to said first shaft (11), for at least a first rotational phase, when said second shaft (12) rotates according to said closing direction (W1). Said mechanism also comprises spring means (13A,13B) operatively connected to said first coupling means (15A, 15B), wherein said spring means (13A, 13B) are loaded during said first rotational phase and release their elastic energy on the two shafts (11, 12) by means of said first coupling means (15A, 15B) when said first rotational phase has been completed.

摘要： A switching apparatus comprising one or more electric poles.
For each electric pole, the switching apparatus comprises a first pole terminal, a second pole terminal and a ground terminal. In operation, the first pole terminal can be electrically coupled to a first conductor of an electric line, the second pole terminal can be electrically coupled to a second conductor of said electric line and the ground terminal can be electrically coupled to a grounding conductor.
For each electric pole, the switching apparatus comprises a plurality of fixed contacts spaced apart one from another. Such a plurality of fixed contacts comprises a first fixed contact electrically connected to the first pole terminal, a second fixed contact electrically connected to the second pole terminal, a third fixed contact electrically connected to the ground terminal and a fourth fixed contact electrically connectable with the second fixed contact.
For each electric pole, the switching apparatus further comprises a movable contact, which is reversibly movable about a corresponding rotation axis according to opposite first and second rotation directions, so that said movable contact can be coupled to or uncoupled from one or more of the above-mentioned fixed contacts, and a vacuum interrupter comprising a vacuum chamber, in which a fixed arc contact and a movable arc contact are enclosed and can be coupled or decoupled.
For each electric pole, the switching apparatus further comprises a motion transmission mechanism operatively coupled to the movable arc contact of said vacuum interrupter. The motion transmission mechanism is actuatable by the movable contact to cause a movement of said movable arc contact along said translation axis, when said movable contact moves about said rotation axis.

摘要： The present invention relates to an operating mechanism (1) for M.V. earthing switch comprising an operating disk (10) rotating about a main axis (100), a connecting assembly (11) which connects operatively said operating disk (10) to said earthing switch. The operating mechanism (1) also comprises an operating lever (12) for rotating said disk (10) from a first angular position to a second angular position according to a closing movement (Wl) and from second angular position to said first angular position according to an opening movement (W2). According to the invention the operating mechanism (1) comprises an interlock assembly (15) that prevents a re-closing movement of said disk (10) when, starting from said second angular position and according to said opening movement, said disk (10) reaches a pre-established angle (α).
