Definitions

  • the invention relates to a NH fuse switch disconnector with switch frame and with respect to this Movable cover, in which the fuse links next to each other transversely to their longitudinal direction arranged, separated from each other by at least one phase partition and by means of their Handle straps are held by suspension parts, with a device for releasable locking of fuse links is provided, in each of which a spring-loaded bolt with the respective grip tab can be brought into locking engagement, with at least two bolts on a common slide are attached, which counter to the biasing force of a spring is displaceable and brings the latches from the handle tabs out of locking engagement.
  • DE 74 17 818 U1 shows a tool designed as a handle insert with which several Fuse links can be pulled out of their circuits or inserted into them.
  • the tool has T-shaped recesses into which the tabs of the fuse links are inserted can be used.
  • a locking bar can be moved lengthways using a handle the fuse links are moved so that part of the T-shaped recesses is blocked and the grip tabs are held securely in the tool.
  • the object of the invention is therefore to provide a NH fuse switch disconnector of the type mentioned to create, in which the removal of the fuse links easily, with great reliability and can be done at any time without touching personnel.
  • this object is achieved in that the slide crosswise in the transverse direction is displaceable to the longitudinal direction of the fuse links arranged in the disconnector and that it extends through a side wall of the lid to form a button.
  • the Slider thus extends at least over one, preferably over two or three side by side arranged fuse links in this cross direction, because the fuse links sit crosswise so that their longitudinal directions are parallel.
  • the preload the spring naturally also acts in this transverse direction, because it presses the Slider in locking engagement. Without touching a fuse link by the hand of a Users can remove one or even three fuse links from the cover at the same time of a switch disconnector. So even with very warm fuse links a removal possible immediately after switching off the consumer.
  • the lid is on one embodiment pivotable relative to the switch frame. It is also particularly advantageous the possibility to make the cover removable from the switch frame. The unlocking is evident and removing the fuse links easily and without problems and risk of injury possible.
  • the button extending through the side wall of the cover in the said transverse direction protrudes half a finger width laterally out of the side wall. This is the key easily accessible for every user. But it can also be useful at the point of passage a small recess in the side wall of the button so that the button accessible and to be operated by the user in the same way from the outside, nevertheless the outer contour of the entire lid is not exceeded. This allows compact Mount the switch disconnectors close together so that they do little Need space.
  • the bolt is as a web with the Slider connected hook formed, which engages around the grip tab.
  • This structure advantageously allows the arrangement of the plate-shaped or substantially flat Handle tab between the slide on the one hand and the hook or bolt on the other.
  • the rest- or locking surface of the hook encompasses the grip tab in this way.
  • the unwanted pressing out of the grip tab in the longitudinal direction of the fuse link avoid upwards by the hook that grips the handle tab from above, while below, i.e. with regard to the tab on the side opposite the hook of the slider is arranged.
  • the slide has an elongated box profile and at the end opposite the key receives a compression spring.
  • the slide can be for example, from solid, electrically insulating and durable plastic or injection molding.
  • the mentioned one can Compression spring can be received and locked in the cavity of this slide. It supports itself against the side wall of the cover or an intermediate web in the cover, which is opposite the side wall with the recessed grip through which the button protrudes.
  • the slide can also be fastened between one on the cover Arrange the guide bracket and a preferably removable cover front wall in a sliding manner.
  • This configuration significantly improves the installation of the slide with or without its hook.
  • the slider is elongated and arranged side by side over all three Fuse links, he can from, i.e. simple from the front wall of the lid be used without unscrewing other parts on the cover beforehand.
  • a part of the front cover as a window or is even designed as a sliding window. You can do this with the right construction for the Assemble the slider, then snap the slider in the shape of the elongated one Insert the box profile against the compression spring and then the window again snap in.
  • the guide angle mentioned which in cross section is L-shaped in one embodiment is, can have legs so long that the leg heights the cross-sectional dimensions of the Slide. Then the tab can like the L-shaped guide bracket up complete the second free leg of a U.
  • the slidable reciprocating slider is then enclosed between the handle tab and the guide bracket as in a cage. According to either the front wall of the cover or its sliding window can close the guide bracket close a closed box housing. Tilting and jamming of the slide before and while pressing the button is then excluded.
  • a sliding window With a test hole for voltage measurement, the hole can be pushed through the slide be covered. After pushing up this window, the hole of the covering walls (e.g. the slide) vertically in the longitudinal direction of the fuse link away and clears the space behind to the grip tab for voltage measurement.
  • the slide and the latches are in one plane the hanging parts leaving an insertion slot and behind the front cover wall are movable.
  • the elongated slide can be thought of as being placed in a vertical plane, which is parallel to the front wall of the lid. The normal direction of view is then perpendicular to this Level.
  • this is the one considered here preferred embodiment opposite to the viewing direction close (1- 5 mm) in front, or that The window or the sliding window is there. Between this front cover or the The window or the sliding window is there.
  • an inlet slope is formed similar to other spring-loaded bolts can also be the plate to be locked here considered embodiment namely the grip tab, when pushing in against the Run in chamfer and thus counter the spring pressure in the longitudinal direction of the Push the slide away so that the locking surface or locking surface when inserting the grip tab is pushed to its end position to the side after positioning the Snap the grip tab back into locking engagement.
  • the inlet slope should be on the restricted area of the Riegel's opposite side or next to it. You then need to insert the Locking tabs are not a special tool to slide the slide in with its bolts to bring the unlocking position.
  • Another advantageous embodiment of the invention is characterized in that Slider approximately perpendicular to its longitudinal and sliding direction at a distance from each other protrude arranged blocking webs. Similar to the first considered embodiment with the hook-shaped bolt, which is also connected to the slider via a web, the bars themselves are designed as such bridges. The hook at the end is missing this Embodiment does not encompass the grip tabs to be locked but lies down on one side in front of this, so that the tabs on this side are not without deliberate unlocking can be taken out or fall out.
  • the number of blocking bars corresponds to Number of fuse links to be locked in the switch disconnector.
  • the fuse link generally designated 1 in the embodiments shown here is attached via its grip tab 2 in the suspension parts 4 forming an insertion slot 3
  • the suspension parts 4 are in the cover 6.
  • the front cover of the cover 8 is closed at the front by a sliding window 9, in the test holes above and below 10 are provided for the voltage test.
  • the switch frame 5 has phase partitions 24, which are between the fuse inserts 1 not shown up to the position of the Slider 14 extend.
  • Cover 6 can be pivoted about pivot point 25 using bearing guide 26 can be pivoted up into the open position (not shown) by pulling the handle 7 in Figure 1 moves to the left and in Figure 2 to the left.
  • the switch frame 5 is on the mounting holes 27 for mounting on a base plate, for example on the plate of a closet.
  • the upper part of the cover front wall 8 is perpendicular in one plane cut to the paper plane of Figure 1 and through the longitudinal direction 11.
  • the cover is also stiffened by this guide bracket 29 The place within this guide angle 29 behind the sliding window 9 is just enough for Recording of the hollow, cross-sectionally U-shaped box profile of the slide 14 on the outside at the free end of the upper leg of the U, the bars 15 are formed vertically upright.
  • the cross-sectional design of the slide 14 of the other embodiment shown in FIG. 5 is structured similarly.
  • the user can push the slide by pressing in the transverse direction 12 14 push against the force of the compression spring 16 out of the position shown in FIG.
