Definitions

  • the invention relates to a power switch, consisting of a housing with a lower part and side walls attached to it and with connections for busbars, from a switching cage movable relative to the housing, transversely to its longitudinal axis, with fuse inserts and guide bars arranged thereon, and from a rigid mechanical switching lever with a spacing mutually arranged connecting elements which are guided by means of complementary parts in the side walls of the housing, of which the one connecting element on the shift lever is designed as a pivot which is guided in a slot as a complementary part in the side wall and of which the other connecting element on the shift lever as Bearing pin is formed, which is arranged in a spaced from the elongated hole and essentially parallel to this, elongated recess as a complementary part in the side wall, the elongated recess after is open to the upper edge of the housing on the lever side, and has a bearing pocket at the opposite inner end for non-positive support of the bearing pin on the switching lever.
  • NH fuse-links are switched with such known load-switching strips, and for this purpose they are used in low-voltage distributions of energy supply companies in industrial companies and large buildings.
  • these devices In addition to protecting the connected electrical circuits, these devices also have the task of isolating certain systems or power supplies from a power supply via a safe isolating path during inspection work.
  • Known NH fuse switchgear are installed in control cabinets. Operating elements are accessible from the outside through appropriate front cutouts, or they can be covered behind closed doors. In accordance with the safety regulations for work on electrical systems, the switching device must be secured against unauthorized switching on. In known industrial systems, this is done in such a way that the device is blocked in the disconnected position by up to three padlocks. These padlocks can only be removed by those who carry out work on the activated systems. Securing against restarting can also be done by locking the switch cabinet in which the switchgear is located.
  • the depth of the switchgear in the disconnected position strongly influences the cabinet depth in such cases. Also in control cabinets where the controls accessible from the outside, the depth of the switchgear in the disconnected position is an important design feature, since device parts that protrude too far into the operating aisle in front of the control cabinets can have a disruptive or even accident-causing effect.
  • the invention is therefore based on the object to provide a power switch of the type mentioned, in which an even smaller space requirement is achieved in the switched-off state and nevertheless low actuating forces are achieved on the shift lever, although at least two fuse links can be switched simultaneously with this strip.
  • This object is achieved in that a curved free-wheel link is provided between the bearing pocket and the upper edge of the housing.
  • a rigid, mechanical, integral switching lever is used, which is long enough to achieve low switching forces, but which, when not in use, namely in its rest or parking position, is arranged parallel to the housing, so that the entire switching strip is both in the on as well as in the off state only requires a relatively small installation depth. Due to the mechanical, one-piece design of the shift lever, even if it is made of plastic for safety reasons, great rigidity and mechanical strength is achieved, so that the switching takes place reliably for the user. The person skilled in the art recognizes the stability of the safety edge according to the invention particularly from the one-piece, strong plastic lever, in which no joints and no parts which are movable relative to one another are permitted.
  • the switching cage is moved with the aid of this one-piece switching lever by means of pivot pins and bearing pins from the operating position into the disconnected position, in which the switching cage moves substantially perpendicularly to the longitudinal axis of the housing and approximately parallel to the slot mentioned to the front away from the mounting plane ( into the disconnected position) or back to the level (closed position).
  • the construction depth can be achieved when using the power switch strip according to the invention by moving from the disconnected position into an additional position, which is also an open position and at which is achieved in the elongated recess by the curved free-wheel backdrop free-running of the bearing pin. Due to the free-wheeling linkage according to the invention, the elongated recess is created so large that the bearing pin on the shift lever disengages from the housing wall and pivoting of the shift lever into the parking position is possible, in which the shift lever is approximately parallel to the longitudinal axis of the housing. This shifting of the shift lever in parallel position with the advantage of the ultimately small overall depth is achieved by shifting the pivot point of the shift lever from the bearing pin located in the freewheel area to the pivot pin in the end position in the elongated hole.
  • the switching cage when the load switch strip is opened, the switching cage, based on the housing, can be pulled out from the first operating position via the second off position into the third additional position, and in this third additional position the rigid long switching lever can be moved via the freewheeling movement of the Bearing pin are brought into a parking position, in which the shift lever is parallel to the longitudinal axis of the housing with the advantage of the small depth due to the compact design.
  • the invention further provides that a locking unit with movable keys and locking lugs is articulated on the switching cage in such a way that the locking lugs engage with the respective side wall of the housing can be brought and preferably the shift lever can be locked in its parking position approximately parallel to the longitudinal axis of the housing with the locking unit.
  • a lock can be provided both in the closed and in the open position of the switch cage, with the result that the user does not switch into the disconnected position or into the closed position without authorization.
  • This provides the option of moving from the disconnected position, e.g. if a machine has been switched off to prevent accidental restart, for example in order to prevent risk of injury to a worker working on the machine.
  • the switching lever can also be locked and locked in the park position corresponding to the disconnected position. If the buttons on the locking unit are configured appropriately, their operation can also be prevented in the open state.
  • the locking unit is plate-shaped, lies flat next to a phase partition of the switching cage, is articulated via pivot points on this phase partition and has two opposite latching lugs and buttons.
  • This allows a particularly effective locking of a relative movement between the switching cage and the housing, because the phase partition connects the two parallel side walls of the housing, and the two locking lugs engage in stops in each of the side walls, so that there is no undesired tilting in one direction it is possible to overcome the locking.
  • each of the keys which can be pivoted relative to one another and each of the latching lugs projecting outward from a deflection lever is articulated at an extra pivot point. This results in good kinematics for the locking unit with symmetrical movements and reliable movement of the locking lugs when the buttons are pressed.
  • the locking unit thus advantageously prevents an undesired shifting of the switching cage from the second off position into the additional parking position and acts as a defined lock during the transition from the aforementioned second position into the third position without actuation of the locking lugs.
  • the locking device ensures when switching on that the switch cage can only be moved into the operating position when the latch is deliberately unlocked.
  • each key and each deflecting lever with locking lug is connected to a yoke arranged in the central region of the plate-shaped locking unit via a respective tie bar.
  • a locking unit can be actuated easily and with low forces, but these forces are nevertheless sufficient to pull out the catches of stops on the side walls of the housing practically perpendicular to these side walls; even with a stronger contact pressure, if frictional forces could counteract such a pulling movement.
  • the locking lugs can be designed so that they can be secured at different points in the locked position, so that practically the position of the switch cage can be locked outside or inside.
  • the plate-shaped locking unit can be produced as a one-piece molded part, but also as a stamped part, preferably made of plastic.
  • Locking unit and shift lever can then be designed so that a crossbar attached to the shift lever has a recess which comes to lie in the parking position close to the hole in the button of the locking unit, so that a padlock can be easily passed through both holes.
  • This assignment of the shift lever and locking unit prevents the shift cage from moving from the operating position (switch-on state) to the disconnected position (switch-off state) and / or vice versa.
  • a guide groove extending approximately perpendicular to its longitudinal axis is provided in the respective side wall of the housing and is interrupted by a stop.
  • This guide groove runs approximately parallel to that mentioned at the beginning Elongated hole for the pivot pin, ie the groove extends in the direction transverse to the longitudinal and transverse axes of the housing, ie perpendicularly from the mounting level for the safety edge in the direction of the device depth.
  • the shift cage can be pulled out or pushed in substantially in a straight line relative to the housing, these actuating forces being applied with the aid of the shift lever.
  • At least one guide groove extends into each of the side walls, because corresponding, complementarily designed guide webs can slide in these guide grooves on the switch cage, so that the relative movement between the switch cage and the housing can take place with the aid of these guide elements.
  • the abovementioned stop in the guide groove ensures that locking lugs of the locking unit are stopped at certain points in such a way that the switch cage strikes the position at certain positions with respect to the housing. Only when the locking lugs are disengaged from the stops by actuating the buttons can the switching cage move further with respect to the housing.
  • the elongated hole and the elongated recess in the side wall of the housing run essentially parallel to the groove for the latching lugs, and the elongated hole is arranged at a distance between the elongated recess and the groove.
  • the shift lever carries the inside of the already mentioned bearing journal, the "long lever" of the shift lever being between the outer handle part and this bearing journal, to which the “short lever” of the shift lever lies at an angle, namely on the route between the bearing journal and the Above-mentioned pivot pin on the shift lever, via which the shift cage is lifted out or pushed in relative to the housing when the shift lever is actuated.
  • pairs of guide webs extending parallel to the elongated hole are attached on both sides, at least one of which is provided with a spring-loaded support which is provided with the actuating cam can be brought into engagement on the cheek of the shift lever.
  • guide grooves are provided which run perpendicular to the fastening plane and in which the guide webs of the shift cage can slide.
  • two guide webs or, in a correspondingly different embodiment, two pairs of guide webs are also attached to each transverse side of the switching cage, the locking unit being mounted in the region of the one guide web or pair of guide webs and the device with the spring support at a distance therefrom on the other guide web or pair of guide webs is provided.
  • This arrangement distributes the forces acting on the switch cage. If one had only the guide groove with the stop for the locking by the locking lugs of the locking unit, the locking would be asymmetrical against pulling out and pushing in of the switching cage, so that tilting of the switching cage in one direction or the other would not be excluded.
  • the supporting forces are symmetrized in the event of unauthorized or unintentional switching on or attempted switching off.
  • the outer that is to say the upper edge of the housing arranged on the shift lever, stands like a stop of the spring support and thereby prevents the shifting cage from moving relative to the housing.
  • the spring support can be actuated from the locking position into the unlocking position and vice versa with the aid of an actuating cam which is formed on the cheek of the shift lever.
  • the advantage of the spring support lies in the increased ease of use by creating defined conditions.
  • the movement of the shift cage from the park position towards the operating position is only possible if the actuating cam on the cheek of the shift lever has come into engagement with the spring support, and this only succeeds when the shift lever is swiveled up in such a way that the inner bearing journal is located at the opposite end is guided over the freewheel link until it reaches the area of the bearing shell.
  • the embodiment shown here is an NH fuse-switch disconnector, the fastening plane of which, as shown in FIG. 11, is the paper plane and, according to FIGS. 1 to 3, runs perpendicular to the paper plane through the left edge of the housing 1, the longitudinal axis 2 of which is shown in broken lines in FIG is. This is parallel to the mounting plane and perpendicular to the transverse direction 3 of the housing 1, which can be seen in broken lines in FIG.
  • the housing has a lower part 4 and on this outside two side walls 5, 5 ′, so that in cross section along the line AA in FIG. 2 there is essentially the shape of a U for the housing 1 ( Figure 4).
  • Connections 6 for current busbars, not shown, which are electrically connected to fuse inserts, not shown, are of course also provided on the housing 1.
  • the switching strip Separately from the housing 1, the switching strip also has the switching cage 7 with fuse inserts attached to it, one phase partition 7 'of which can be seen in FIG.
  • guide grooves 8 are provided in each of the side walls 5 and 5 'of the housing, which separate the side walls 5 and 5' in the longitudinal direction 2 into three thirds surfaces, with the representation in FIGS. 1 to 3 and 11, the top third at the top and the bottom third at the bottom is to be thought.
  • guide webs 9 fastened to the switch cage 7, which divide the switch cage 7 in a corresponding manner, seen in the longitudinal direction, into three thirds.
  • the power switch strip also has a shift lever 11 which has cheeks 12 and a crossbar 13 in its inner region. At its inner end opposite the outer gripping end there are bearing pins 14 and pivot pins 15 arranged at a distance (small lever) therefrom.
  • the pivot pins 15 are received in an elongated hole 16, while the bearing pins 14 are guided in an elongated recess 17 parallel to the elongated hole 16.
  • a locking unit 18 is articulated on the switching cage 7, which can be seen most clearly from FIG. 4.
  • the shape of the locking unit 18 is plate-shaped, as can also be seen from the figure 12 sees. In the middle, it has a yoke 19, on which 20 keys 21 are articulated upwards and outwards via webs which, when actuated for unlocking in the direction of arrows 22 (FIG. 4), can be moved towards one another in such a way that they move around the pivot points 23 turn.
  • the yoke 19 moves in the upward direction 10 upwards, with the result that the deflection levers 25 articulated on the yoke 19 via further tie bars 24 with outwardly projecting locking lugs 26 pivot about the pivot points 27 in such a way that the deflection levers 25 with the locking lugs 26 in Direction of arrows 28 - that is, in the unlocked position.
  • the articulation of the plate-shaped locking unit 18 flat next to the phase dividing wall 7 'of the switching cage 7, namely the articulation via the pivot points 23 and 27 on this phase dividing wall 7', can be seen clearly from the illustration in FIG.
  • the purpose of the locking unit 18 is to engage or detach the locking lugs 26, which extend on both sides to the side walls 5, 5 'of the housing 1, with these side walls 5, 5', namely to Switch cage 7 to be able to move relative to the housing 1 or not.
  • FIGS. 5 to 7 are expediently considered for this purpose.
  • the guide groove 8 can be seen in the respective side wall 5 of the housing 1, which is interrupted at a certain point by a stop 29.
  • the upper guide web 9 has a recess 33, so that a spring support 34 results. This comes into engagement with the actuating cam 35 on the cheek 12 of the shift lever 11 as shown in FIG. 8, the spring support 34 being pressed within the region of the outer contour of the guide web 9 in order to reach the position in FIG. 8.
  • the guide web 9 can be pushed into the guide groove 8 to the left, i.e. you can push the switch cage 7 down into the housing 1.
  • the shift lever 11 has reached its position in FIG. 3, from which the bearing pin 14 in the elongated recess 17 reaches down to the bottom left into the inside bottom of the elongated recess 17.
  • the spring support 34 can spring open into the position in FIG. 9 after the state in FIG. 3 has been reached, that is to say the switching cage 7 has been pulled out into its outermost position. If in this position of FIG. 3 the switching lever 11 is switched to the parking position shown there in dash-dotted lines, namely parallel to the housing 1, then the actuating cam 35 has also left the spring support 34 again, and this springs open for locking (FIG. 9). If the switch cage 7 is now pressed unintentionally or unauthorized from the outside to bring it back into the operating position (switched on), then the catch 26 supports on the one hand according to the position in FIG. 7 via the stop 29 and on the other hand the spring support 34 via the upper edge 37 on the switch lever side of the housing 1 from the switch cage 7. Protection against unauthorized restarting is avoided without tilting.
