Abstract
The arrangement for mutually locking the actuation of at least two power switches (A, B, C) has a position indicator (7) and an evaluation apparatus (10) for each power switch (A, B, C). A carrying plate (6) accommodating the position indicator (7) and the evaluation apparatus (10) is assigned to a side wall of the power switch (A, B, C). A shaft coupling (30) and a driver coupling (31) establish the connection with a switching shaft or a control shaft, respectively, of a device (32) that releases or locks the actuation of the power switch (A, B, C) when the carrying plate (6) is mounted on the power switch (A, B, C) or on a withdrawable rack (26).
Claims6
A mutually locking device comprising:
- at least two power switches, each power switch including a side wall and a switching shaft, each switching shaft being accessible on one of the side walls, each power switch including a control element accessible on one of the side walls, each power switch including a device that releases and locks the actuation of one of the power switches, each device that releases and locks the actuation of one of the power switches being accessible on one of the side walls, each power switch including a position indicator producing a mechanical signal corresponding to a switching position, each power switch including an evaluation apparatus controlled by one of the mechanical signals, each evaluation apparatus operating one of the control elements, each power switch including a common carrying plate, the evaluation apparatus and the position indicator of each power switch being arranged on one of the common carrying plates, each common carrying plate being arranged parallel to one of the side walls, each evaluation apparatus including at least one input slide and at least one output slide that is coupled to the control element of the respective power switch in one position of the input and output slides and uncoupled from the control element of the respective power switch in another position of the input and output slides;
- and
- a plurality of mechanical transmission members connected to at least one of the evaluation devices and at least one of the position indicators, the mechanical transmission members transmitting the mechanical signals, the evaluation apparatuses being controlled by the mechanical signals to actuate at least the control element of one of the power switches.
