Definitions
- the invention relates to a switching system which comprises at least one switch fuse unit with a fuse link which can be switched back and forth between an on position and an off position.
- a switching system further comprises a switch for closing and interrupting the circuit of the power system and a switching and blocking device which prevents the circuit from being closed by the switch.
- the switch for closing and interrupting the circuit of the switching system is intended to make it possible for all fuse links in the switching system to be contacted without current and voltage before the circuit of the overall system is closed. This prevents switching arcs on the sensitive contacts of the fuse links and increases the service life of the fuse links.
- a blocking device is intended to prevent the circuit from being closed via the switch, although not all of the fuse links are in their switched-on position, thereby avoiding incorrect operation of the switching system, which can lead to the above-mentioned switching arcs and damage to the fuse link in particular.
- the object is achieved by a switching system according to claim 1, claims 2 to 8 relate to particularly advantageous embodiments of the switching system according to the invention.
- a combined switching and blocking device is provided in the switching system, a blocking element with at least one blocking rod per switch securing unit being fastened to an actuating lever of the switch for closing and interrupting the circuit.
- a locking element is also provided with an opening, which is arranged in the switch fuse unit so that it can always be switched back and forth together with the fuse link.
- Each blocking bar is only then in the opening of the associated locking
- locking element can be inserted when the associated fuse link is in its switch-on position; and the operating lever of the switch can only be flipped to close the circuit if each of the blocking rods can be inserted into the opening of its associated locking element.
- the inventive design of the combined switching and blocking device automatically ensures that the circuit of the switching system is not closed
- the switching system according to the invention can consist of only one switch fuse unit. However, it preferably consists of a plurality of switch fuse units connected in series.
- the switching and blocking device according to the invention is particularly used in switching systems with a plurality of switch fuse units for a three-phase circuit.
- the switch fuse units can in particular be attached to busbars.
- the structure of the individual switch fuse units can be different.
- the fuse link can be switched back and forth directly in the switch fuse unit between the switch-on position and the switch-off position.
- a fuse plug is provided for receiving the fuse link, the fuse plug either being switchable directly between a switch-on position and a switch-off position or being insertable into a rocker switch of a switch fuse unit, which in turn is designed to switch back and forth.
- the locking element can be attached directly to the fuse link, but it is preferably attached to the fuse plug or a rocker switch, so that standardized fuse links can be used without the locking element being manually detached from the old fuse link and to the new one when the fuse link is replaced must be attached or, under certain circumstances, complex measures must be taken so that the fuse link is automatically connected to the locking element when exchanged becomes .
- the locking element is preferably formed integrally with the rocker switch in order to achieve a simple structure of the system.
- the locking element is preferably designed as a guide element which defines and controls the switching movement of the fuse link or the fuse stopper or the switching rocker in order to ensure a smooth and exact switching process.
- the locking element preferably has at least one latching device which engages with corresponding latching elements in the switch fuse unit in the switch-off position and / or the switch-on position of the fuse link.
- the end positions of the fuse link or the fuse plug or the rocker switch are defined as defined, latched end positions.
- Figure 1 is a cross-sectional view through a portion of an embodiment of the switching system according to the invention with a fuse link in the off position.
- FIG. 2 shows the embodiment of the switching system shown in FIG. 1 with the fuse link in the switched-on position
- FIG. 3 is a cross-sectional view taken along line A-A in FIG. 1.
- Fig. 1 shows a portion of an embodiment of the Switching system according to the invention, which consists of several switch fuse units 10. For the sake of simplicity, however, only a partial area of a single switch protection unit is shown. The other switch fuse units are constructed analogously.
- the switch fuse unit 10 has a fuse plug 40 into which a fuse link 20 is inserted.
- the fuse link 20 is contacted by a lower contact 50 in each position of the fuse stopper 40, while an upper contact 60 is not in contact with the fuse link 20 in the switched-off position of the fuse stopper 40 shown in FIG. 1.
- the lower contact 50 of the switch fuse unit 10 is biased by a spring 51 so that a fork-shaped sliding contact 52 is in constant contact with the fuse link 20.
- the upper contact 60 is only guided when the fuse stopper 40 is pivoted onto a mating contact of the fuse link 20 (see FIG. 2).
- a locking element 35 in the form of a segment of a circle is attached to the securing plug 40, which is simultaneously designed as a guide and support element and is guided in a guide rail (not shown) of the housing 11 of the switch fuse unit 10.
- the fuse plug 40 can be inserted into the switch fuse unit 10 and can be removed therefrom, while the locking element 35 is an integral part of the switch fuse unit 10. The connection between the two elements will be explained below in connection with FIG. 3.
- the locking element 35 has an opening 36 into which a blocking rod 33 of the blocking element 32 of the switching and Blocking device 30 can be inserted when the fuse plug is in its switched-on position.
- the blocking rod 33 of the switching and blocking device 30 abuts against an edge region of the locking element 35, so that the actuating lever 31 of the switching and blocking device 30 cannot be flipped over.
- the blocking rod 33 is part of the blocking element 32, the blocking element in a branched manner comprising further blocking rods (not shown) for further switch protection units.
- the blocking element is made of a rigid material, so that distortions of the blocking element are avoided.
- a locking element 37 of the locking element 35 is in engagement with a corresponding locking element 38 of the switch fuse unit 10, so that the switch-off position shown in FIG. 1 represents a locked end position of the fuse plug 40 with the fuse link 20.
- the fuse plug 40 with the fuse link 20 is in its switched-on position.
- the fuse link 20 is now in contact both with the lower contact 50 and with the upper contact 60 of the switch fuse unit 10.
- the position of the locking element 35 has also changed.
- the opening 36 of the locking element 35 is aligned with the blocking rod 33 of the switching and blocking device 30, so that the actuating lever 31 can be moved into an on position, whereby the circuit of the switching system is closed.
- the blocking rod 33 is simultaneously in introduced the opening 36 of the locking element.
- the dimensions of the blocking rod 33 correspond to those of the opening 36 of the locking element 35, so that a precisely fitting insertion takes place and the securing plug 40 with the securing insert 20 cannot be pivoted out of the switched-on position.
- the locking element 37 of the locking element 35 is in engagement with a second locking element 39 of the switch fuse unit, so that, regardless of the position of the actuating lever 31 and the blocking of the fuse stopper 40 by the blocking rod 33 in the switched-on position, a latched end position of the fuse plug 40 is ensured ,
- the blocking element 32 with a blocking rod 33 is a rigid element for each switch fuse unit 10, the operating lever cannot be placed in the position shown in FIG. 2 if only one of the fuse plugs 40 is not in its switched-on position.
- Fig. 3 shows a cross section through the securing plug 40 and the locking element 35 along the line AA in Fig. 1.
- the securing plug 40 has a fastening element 41 in the form of a dovetail, which engages in a corresponding counter-element 42 of the locking element 35, so that a there is a positive and frictional connection.
- the fuse plug 40 can therefore be easily inserted into the switch fuse unit 10 from above, with a reliable connection between the fuse plug 40 and the locking element 35 being automatically ensured via the fastening element 41 and the counter element 42.
