Definitions

  • the invention relates to a load switch with a vacuum switch according to the preamble of patent claim 1.
  • load switches must be able to switch the load currents on and off. When arranged in control panels or the like. easy detection of the open state of the circuit breaker and a small space requirement are required. Such load switches should also be able to withstand a large number of switching operations, i.e. be durable, which requires an arc-free switching. Small, long-life vacuum switches which can be switched without arcing are known, but because of their very small electrode spacings in the open state, e.g. With switches for 2.7 kV less than 10 mm, the open switching status cannot be recognized safely and easily, especially when used in control panels.
  • the invention has for its object to provide a durable, small-sized, arc-free switchable switch of the type mentioned, the respective switching state, in particular its open state, can be easily and safely visually detected and which can be used for many switching operations.
  • An upper support insulator 1 and a lower support insulator 2 are attached to a frame (not shown).
  • a receptacle contact 4 of the disconnector 3 connected to a connection terminal 22 is held and on the lower support insulator 2, a sliding contact 5 connected to a connection terminal 21 is held, both lying on a common longitudinal axis.
  • An actuating unit of the load switch adjustable in the direction of the longitudinal axis projects through the sliding contact 5.
  • This longitudinally adjustable actuating unit consists of a vacuum switch 6 with a fixed electrode 6c and a control rod 6b which is guided out of the vacuum switch and can be adjusted in the axial direction against the force of a hold-open spring 10 and has an attached electrode 6a.
  • an intrusion contact 7 of the disconnector. 3 with annular bead 7b projecting over the control rod 6b on the circumferential side and a rod flange 7a, between which and the vacuum switch 6 the hold-open spring 10 is clamped.
  • the section between the rod flange 7a and the annular bead 7b is, as will be explained further below, as an annular groove for one Retention device 12a used in the receiving contact 4.
  • a rod-shaped fuse 9 which projects through the sliding contact 5 in the axial direction and is used in its upper end position for power supply, is mechanically firmly connected to the fixed electrode 6c in the axial direction as a conductive connecting element.
  • the rod-shaped fuse 9 is provided at its free end with a contact cap 9a and connected to a mechanical coupling member 8 which is in engagement with a crank mechanism 11 which is actuated by a rotary drive, not shown, so that the longitudinally adjustable actuating unit from the fully drawn Can be brought into the position indicated by dash-dotted lines and vice versa.
  • the contact cap 9a comes into engagement with the sliding contact 5 and the penetration contact 7 of the isolating switch 3 engages with the stationary receiving contact 4 of the isolating switch 3.
  • the stationary receiving contact 4 of the isolating switch 3 consists of contact pieces 12 arranged coaxially to the longitudinal axis within a contact piece holder 13 connected to the connecting terminal 22, which are held together by a surrounding contact ring spring 14 with their free end projections 12a as a retaining device for the actuating unit towards the longitudinal axis.
  • a buffer 16 Arranged in the contact piece holder 13 above the contact pieces 12 is a buffer 16 projecting between them, which is supported by a contact buffer spring 15 on a conductive fixed stop 17 of the contact piece holder 13.
  • the sliding contact 5 consists of the fuse 9 coaxially surrounding contact pieces 18, which are held together by a contact ring spring 20 in an electrically conductive contact piece holder 19, which in turn is attached to the support insulator 2 and is connected to the terminal 21.
  • the hold-open spring 10 is designed in terms of its spring force f 3 so that it keeps the electrodes 6a and 6c of the vacuum switch 6 separate from one another when the disconnector 3 is open.
  • the spring force f 3 of the hold-open spring 10 is sufficient when introducing the penetration contact 7 into the receiving contact 4 (arrow direction P) and spreading the contact pieces 12 through the annular bead 7b around the electrodes 6a, 6c against the spring force component f 1 of the contact ring spring acting in the opposite arrow direction Q 14 continue to be kept separate.
  • the hold-open spring 10 is also only pressed together by the opposite spring force f 4 of the contact buffer spring 15 when the penetration contact 7 strikes the buffer 16, the electrodes 6a and 6c making contact.
  • the spring force f 1 of the contact ring spring 14 is designed so that it not only ensures a certain current transfer between the penetration contact 7 and the contact pieces 12, but also temporarily the engagement between their retaining end projections 12a and the said annular groove between the annular bead 7b and the rod flange 7a maintains during the disconnection movement of the disconnector 3 in the opposite arrow direction Q.
  • the electrodes 6a, 6c are disconnected before the disconnector 3 opens.
  • the spring force f 4 of the contact buffer spring 15 is greater than the spring force f 3 of the hold-open spring 10, the reverse force ratio f ' 3 , f' 4 can also be increased with increased spring force f3 f 3 f4 can be provided as long as the fixed stop 17 is present. In this case, the driving force G f ' 3 + f 2 .
  • FIG. 3 A simplified embodiment with a lighter actuating unit is shown in FIG. 3, in which the unchanged parts corresponding to FIG. 1 have the same reference numerals. Only the parts identified by reference numerals 23, 24 and 25 are new or modified.
  • the main difference from the embodiment according to FIG. 1 is that the receiving contact 24 of the disconnector 3 is part of the actuating unit.
  • the crank mechanism 11 is in turn connected to the fuse 9 via the coupling member 8.
  • a contact piece holder 25 for the contact pieces 12 forming the adjustable receiving contact 24 of the disconnector 3 is arranged, in which the buffer 16, the contact buffer spring 15 and the fixed stop 17 are accommodated in the same way as in FIG. 1.
  • An L-shaped support 23 for the immovable vacuum switch 6, which is conductively connected to the connecting terminal 22, is held on the upper support insulator 1.
  • the electrode 6c is conductively connected to the connection terminal 22 via the carrier 23.
  • a well-conductive, appropriately dimensioned Ku p ferrohr can be used, which can transmit the highest occurring current properly and without risk of damage from the sliding contact to the load or disconnector.
