Abstract:
The invention relates to an arrangement for attaching a switch (2) control shaft (1) to a switch (2) pipe shaft (3), where the control shaft (1) is mounted partly in the switch (2) pipe shaft (3) and tightened to the switch (2) pipe shaft (3) by a screw (4). The arrangement comprises a tightening piece (6). The screw (4) is arranged to act on the control shaft (1) through the tightening piece (6) so that when the screw (4) is turned, the tightening piece (6) is arranged to press the control shaft (1) against the pipe shaft (3) so that the control shaft (1) tightens fast between the tightening piece (6) and the pipe shaft (3).
Abstract:
A modular switching device comprising a plurality of interconnected modules (2, 3), said modules comprising a control device module (2) and a pole cell module (3), said modules (2, 3) of the switching device being interconnected with a shaft adapted to transfer a torque required for operating the switching device from one module (2) to another module (3). The modular switching de-vice of the invention is characterized in that each module (2, 3) comprises a shaft element (6), and in that said shaft transferring the torque is composed of directly interconnected shaft elements (6).
Abstract:
A switching device comprising a frame (2), a first connector (4) and a second connector (6), the first connector (4) and the second connector (6) extending from inside the frame (2) outside the frame (2), means (8) for connecting the first (4) and the second (6) connector electrically to one another, and one or more gas flow openings (10, 11) provided in the frame (2) and arranged for a gas flow produced by a switching event. In its portion remaining inside the frame (2), the first connector (4) comprises a hole (12) provided for said gas flow.
Abstract:
An auxiliary contact configuration for a switching device, the switching device comprising a frame part (2) and the auxiliary contact configuration comprising a first auxiliary contact position (5) provided in the frame part (2) and arranged to receive an auxiliary contact (8), and a movable auxiliary contact control device (10) comprising a first control element (11) arranged to control the auxiliary contact (8) installed in the first position (5). The auxiliary contact configuration comprises a second auxiliary contact position (6) provided near the first auxiliary contact position (5), and the auxiliary contact control device (10) comprises a second control element (12) arranged to control the auxiliary contact (8) installed in the second position (6) in a manner different from the manner in which the first control element (11) is arranged to control the auxiliary contact (8) installed in the first position (5).
Abstract:
A switching device comprising a working shaft (3) and a control shaft (4) in-stalled in a frame part (2), the control shaft being rotatable and adapted to turn the working shaft, and the working shaft (3) being adapted to change the posi-tion of poles of the switching device. One (4) of said two shafts (3, 4) passes through the other (3).
Abstract:
The invention relates to a fastening arrangement for fastening a switching device to a mounting tray, the fastening arrangement comprising a fastening point (12) formed in the switching device or the like, and a lug (10) to be fastened to the fastening point (12). The fastening point comprises at least three recesses (16) to receive the protrusion (24) in the lug (10) in such a way that the lug (10) is optionally lockable, when being fastened to the switching device, to different positions defined by the recesses (16), one of the positions being a substantially vertical position, another being a substantially horizontal position, and the rest being positions at an angle between these positions.
Abstract:
The present invention relates to a switch device for controlling electrical equipment. Such a switch device comprises a body piece (15), a sliding member (14) and contact surfaces controlled by the sliding member (14), means for latching the sliding member (14) into a closed/open position of the switch and for unlatching the sliding member (14) from said positions, a spring-arming plate (11) and switch actuator springs (10). The invention is implemented by making a slot (33) into the sliding member (14) that controls the second movable set of contact surfaces in the switch and adapting compatible interlock means (34) to the housing or body piece (15) of the switch, said interlock means serving to inhibit the movement of said sliding member (14) by virtue of partially entering the slot (33) made into the sliding member (14). Additionally, the spring-arming plate (11) is provided with a projection (32) capable of covering the slot (33) made into the sliding member (14) and thus preventing the interlock means (34) from inhibiting the movement of the sliding member (14) when the switch is being opened or closed. The switch device is also provided with another set of springs (31) for storing the mechanical energy required for a remote-controlled operation.
Abstract:
A switching device comprising a frame (2), in which an actuator (6) adapted to rotate a main shaft of the switching device and rotatable around an axis (12) of rotation, and spring means are installed, the actuator (6) having a 0 position, an 1 position and a first dead point between the 0 position and the 1 position, the 1 position being located by a given angle (α6) in a first direction relative to the 0 position. The actuator (6) also has a testing position, the testing position being located by a predetermined angle (β6) in a second direction relative to the 0 position, said second direction being opposite relative to said first direction.
