Definitions

  • the invention relates to a switchgear for a withdrawable circuit breaker, as is used in particular in training as a control cabinet.
  • a frame which is connected to a connection base plate and contains two fixed side plates attached to the base plate and two movable side plates which are attached to two opposite side walls of the switch.
  • the movable plates each carry two drive shafts, which are held in two guide grooves on the fixed plates. These drive shafts can be moved in the guide grooves by the movement of cam pieces which are equipped with actuating levers which are provided with a handwheel.
  • the switch can assume a retracted position, a test position and an extended position.
  • a locking device for an extension unit is described in EP-A1-0930681.
  • EP-A1-0951122 discloses the energy storage device when pulling out a circuit breaker using the pull-out technique.
  • a circuit-breaker in extension technology with an actuating lever for switching on and off in connection with the position or the position to be assumed of the switch in the extension unit is described in EP-A1-0951123.
  • Circuit breaker leads to a lowering of the permissible load current (derating).
  • the object of the invention is therefore to reduce the design effort
  • connection plates are provided, in which fixed connections to the busbars and plug connections for the circuit breaker are fastened, and that only horizontal guide rails are provided for carrying and driving the circuit breaker.
  • the connection plates and the guide rails are fastened, preferably screwed, in the frame of the switchgear, in particular a switch cabinet. This means that the effort to implement the extension technology is realized to the absolute minimum.
  • connection plates are advantageous to have a modular structure, i.e. dimensioned for the highest nominal current of the smallest size, and to cover all other sizes by parallel connection plates of the same type.
  • the switch itself contains insertable rollers, e.g. Ball bearing, which run in the L- or U-shaped guide rails.
  • the height of the rollers also compensates for the necessary misalignment of the connections, or in other words, the rail connection geometry remains the same regardless of whether a circuit breaker with or without an extension unit is to be used.
  • Figure 1 in a simplified perspective view of an inventive
  • FIG. 1 an electrical switchgear in the form of a control cabinet is shown, of which in turn only the cuboid with omission of the side wall parts
  • Support frame 2 for receiving the current-carrying parts and a retractable and withdrawable circuit breaker is shown.
  • Two U-shaped guide rails 4 are fastened in the supporting frame 2.
  • the guide rails 4 are used to carry and move a circuit breaker 6 which, according to FIG. 2, is equipped with rollers 8 which can be inserted into the underside 22 of the circuit breaker 6 on the one hand and are guided in the guide rails 4 on the other hand.
  • the connection of the incoming and outgoing plug elements 24 of the circuit breaker 6 on the rear is carried out via modular connecting plates 14 from or to vertical incoming and outgoing busbars 12.
  • the connecting plates 14 are of the highest quality in terms of their geometric dimensions and their current carrying capacity Nominal current of the smallest
  • connection plates 14 has two fixed connections 18, in each case one fixed connection 18 to the associated incoming or outgoing busbar 12, each via a horizontally extending connection rail 16.
  • Each connection plate 14 also has two plug connections 20, each for receiving the associated one incoming or outgoing plug elements 24 of the circuit breaker 6.
  • connection plates 14 In each of these connection plates 14, the electrical connection between the incoming and outgoing fixed connection 18 and the associated incoming and outgoing plug connection 20 is realized by electrically conductive connecting parts 19.
  • the remaining components of the connection plates 14 consist of electrically insulating material.
  • Fig. 1 it can be seen that the connection plates 14 are connected to the supporting frame 2 via two transverse, sufficiently mechanically stable fastening strips 15.
  • the connection plates 14 are connected at their two insulating ends via a screw connection 17 to one of the fastening strips 15.
  • the guide rails 4 are connected at their rear end via suitable fastening means, for example screwed angle elements, to the lower fastening strip 14 and at their front end to the supporting frame 2.
  • FIG. 2 From Fig. 2 can also be seen how the necessary offset x between the connecting rails 16 and the rear plug connections 24 of the circuit breaker 6 is compensated for by the height x of the rollers 8 to the underside 22 of the circuit breaker 6.

Abstract

L'invention concerne une installation de distribution pour un disjoncteur amovible. Au moins une plaque de connexion arrière (14), dans laquelle sont fixées les connexions fixes (18) vers les barres conductrices (12) et les connexions enfichables (20) pour le disjoncteur, est prévue par phase. Seuls des rails de guidage horizontaux (4) servent à porter et à déplacer le disjoncteur.
