Definitions

  • the invention relates to a fuse disconnector with a lower part, which has fixed contact parts, with a Cover for the lower part and with a fuse holder with fuses for contacting the fixed contact parts.
  • a generic fuse switch is from the DE-GM 92 08 693.4 known.
  • This fuse switch according to 5 consists of a lower part 1 with the receptacle contacts 2 for the knives 3 of low-voltage high-performance fuses 4.
  • the low-voltage high-performance fuses 4 are held in a fuse holder 5 via holding tabs 6.
  • the fuse holder 5 is not with the lower part 1 connected pivot joint shown.
  • the recording contacts 2 are covered by a cover 7.
  • slots 8 are introduced for inserting the knife 3.
  • On the side facing away from the swivel joint for the fuse holder Side is the cover 7 with a closed to the outside, slot-shaped arc guide 9 equipped, which has an outlet opening 10.
  • This arc quenching device is used to switch off Load currents.
  • the load currents are with peak values of approx. 1 kA relatively low.
  • the arcing that occurs is stopped approx. 10 to 20 ms, i.e. relatively long.
  • the problem area with Switching off load currents lies in front of the contact piece, which is why in this area to solve the problem of arc deflection chambers are provided with the outlet opening 10.
  • the invention is therefore based on the object of a fuse disconnector of the above kind to improve that a damaging influence by turning on on a short circuit occurring metal vapors and ionized gases is avoided.
  • the object is achieved in that chambers in the cover integrated for receiving the fixed contact parts that partitions the chambers fixed contact parts lying next to each other isolate and that the chambers each on the have a wall facing away from the respective fuse.
  • a particularly advantageous embodiment of the invention consists of when the chamber opens on the side facing the lower part is, whereby a targeted pressure relief and a Allows the ionized gases and metal vapors to be discharged becomes.
  • the fuse switch disconnector shown in FIG 1 exists essentially from a lower part 11 with receiving contacts 12 for safety knife 13 of low-voltage high-performance fuses 14, a cover which can be snapped onto the lower part 11 17 and a fuse holder 15 that holds the low voltage high power fuses 14 carries over holding flags 16.
  • the fuse holder 15 is with the lower part 11 via Known rotary joint not shown connected.
  • the Cover 17 covers the receiving contacts 12 and thus serves as protection against contact.
  • Way slots 18 introduced for inserting the safety knife 13.
  • At the swivel joint for the fuse holder 15 facing away from the cover 17 is provided with chambers 19, into each of the receiving contacts 12, i.e. a Fixed contact is made for each phase.
  • the fuse switch disconnector 1 is in a position during the switch-on process shown shortly after swinging open the Fuse holder 15 in which the fuse knife 13 the contacts Touch 12.
  • Arrows 20 show the spread of Metal vapors and ionized gases indicated. These will held by a wall 21 associated with chamber 19 and reflected.
  • the wall 21 lies on the safety knife 13 opposite side of the receiving contact 12.
  • the chamber 19 encloses the receiving contact 12 on all sides by walls, wherein only one of the walls through the slot 18 for contacting of the safety knife 13 with the receiving contact 12 is interrupted. Down, i.e. to the lower part 11 the chamber 12 opened, thereby causing the explosive A targeted spread of metal vapors and gases To offer pressure relief and to derive this.
  • the Wall 21 of the chamber 19 provides a partition to the terminal 22 out, which has a connection opening 23 on the Housing outer wall is accessible.
  • FIG. 2 shows a fuse switch disconnector according to the invention Type shown without a fuse holder and fuses.
  • the connector 22 for connecting a cable lug formed by a wide connection opening 23 in the Housing outer wall is insertable. Without the design of the Cover 17 with individual chambers 19 and the associated ones Walls 21 would contain the metal vapors and ionized gases spread outward unhindered towards the connection opening 23 can and thereby the risk of short circuit significantly enlarge. Otherwise, the same reference numerals as in 1 used because the embodiment is basically the same is trained.
  • FIG. 4 shows the cover 17 in a bottom view, i.e. out the view of the lower part 11.
  • the three individual ones Chambers 19 can be seen for each phase. These are each through the walls 21 and adjoining transverse walls 24 formed that the receiving contact 12 on all sides except for the Surround slot 18.
  • the transverse walls 24 also serve as Partitions between adjacent receptacle contacts 12.
