Definitions

  • the invention relates to a method for controlling an electrical switch module with switching contacts of vacuum interrupters, which can be moved between a "retracted position” and a "extended position", as well as a separating part with separating contacts, which can also be moved in the switch module, with corresponding counter contacts within an encapsulated switching field, in particular a medium-voltage switching field are connectable and disconnectable, as well as with plug contacts and mating plugs - contacts in the low-voltage range, the switching contacts of the vacuum holding tubes to support the switch-on and switch-off processes under the control of a switch-on spring which can be influenced by a switch-on pawl (EK) and one which can be influenced by a switch-off pawl (AK) Switch off spring stand and striking functional positions of the separating part are represented by an "operating position” and by a "disconnected position", as well as a control device for executing conduct of the procedure.
  • a switch-on spring which can be influenced by a switch-on pawl (
  • the basic structure of a medium-voltage switch panel of the type defined at the outset is from the SIEMENS circuit breaker - withdrawable unit type NXAIR M, supplement 2000 to catalog HA 25.71, chapter 4, pages 10 to
  • Chapter 5 of this publication refers to the relevant provisions and regulations for such switch feeders, particularly in connection with aspects of personal and operational safety.
  • Chapter 5 on page 20 of this publication there are also notes for the locking regulations in connection with the invention according to VDE 0670 and IEC 60298. The locking conditions going beyond these regulations are then referred to in chapter 4, page 15.
  • the basic function and mode of operation of the switch-on and switch-off springs of an electrical switch module can be found in the SIEMENS 3AF vacuum circuit-breaker, operating instructions, order number NR.SW 8516 b, in particular in the chapter Drive, pages 3/1 to 3/4.
  • the object on which the invention is based is to define a method for controlling the switch module and a control device which is capable of doing so, with which both the existing regulations and additional conditions can be fulfilled, the control device being constructed in a compact design and largely independent of the switch contacts of the switch module that are used can be used practically universally.
  • U-shaped cross-sectional lifting lever with two differently designed control contours is provided, with which the closing pawl for the closing spring and opening pawl for the closing spring of the switching contacts are controlled in accordance with the regulations.
  • the U-shaped lifting lever is only deflected in the vertical direction at different lifting heights. This takes place in cooperation with the rotatably mounted pivot lever, which in turn can be pivoted radially by a stroke control lever representing the various functional divisions.
  • the different control contours at the free end of the lifting lever in cooperation with the various castors, move the corresponding actuating levers of the on and off pawls, so that the springs responsible for the corresponding switching processes - the switch-on spring for switching on and the switch-off spring for switching off - Can be controlled functionally with regard to their tensioned or relaxed spring states.
  • the sliding rollers are moved by the vertically deflected lifting lever by means of thrust bevels in such a way that the on and off pawl each follow radial deflections.
  • the stroke lever is provided with an elongated hole on both sides in the direction of its stroke deflection, in which the second actuating lever with its pivot bearing is fixed in position on the stroke lever.
  • control device is designed in such a way that when the switch module is moved out of the encapsulated switch panel into the “extended position”, the required state of relaxation of the switch-on and switch-off springs is inevitably brought about.
  • the latch is thus blocked in its radial deflection and can no longer be operated. As long as this state persists, this also applies to manual actuation of the on-off pawl via a button or automatically triggered by a control room. Every attempt to switch on is unsuccessful.
  • This switching-on and switching-off process which takes place in direct succession, is permissible and can be used to monitor the switching processes taking place in the control panel.
  • FIG. 1 shows the front view of the control device SE with the essential lifting lever HH in the sectional plane BB of FIG. 2, while FIG. 2 shows the position of the lifting lever HH within the drive housing AG of the control device SE in a side view represents.
  • both the position of the catch ratchet EV in the release FS of the switch ratchet and the position of the ratchet latch EV in the locking position VS of the switch ratchet are shown shaded. This also applies to the second actuating lever BH2 and the pin lever TH (Fig.l), the interrupted The shaded lines document the state of the release FS of the ratchet lock EV and the continuous shaded lines the state of the locking position VS of the ratchet lock EV.
  • FIG. 2 also shows the vertical drive of the lifting lever HH by the lifting control lever HS representing different functional positions, which is slidably guided along an angle profile bar, not shown, within a switch module, also not shown.
  • the lifting lever (HH) is deflected vertically by the position-dependent recesses and elevations there.
  • the U-shaped cross-sectional lifting lever HH is rotatably supported on one side within the drive housing AG and is provided with different function-related control contours SKI, SK2 at its free ends compared to its pivoting position in the pivoting lever SH.
  • the starting position of the control device SE which here is intended to represent the “operating position” of the switch module, provides that the lifting lever HH with the second sliding roller GR2 is just at the beginning of the second thrust slope SS2, which widens downwards and at which the second actuating lever BH2 is not yet influenced by the radial deflection RA.
  • the EK latch is then not locked, while the plug contacts are electrically conductively connected to the mating plug contacts in the low-voltage range. At the same time, the isolating contacts are also in an electrically conductive connection with the counter contacts in the main voltage range.
  • the second sliding roller GR2 With the second control contour SK2 of the lifting lever HH is at the beginning of its upward vertical deflection in a first switching sequence with its second thrust slope SS2, the second sliding roller GR2 is guided along the sliding deflection GA.
  • the second actuating lever BH2 which is rigidly connected to the second sliding roller GR2, is subjected to the radial deflection RA and thus releases the switch-off pawl AK.
  • the second actuating lever BH2 then engages with the pin lever TH in such a way that the latch catch EV is deflected from the release FS of the latch EK to the locking position VS of the latch EK.
  • the switch pawl EK and thus the activation of the switching spring for the switch contacts, is locked in this state.
  • the second sliding roller GR2 is then in the area of the straight line SG of the lifting lever HH - its second control contour SK2 with its push pin ST comes into connection with the Einalklin - Key lock EV, in which the switch pawl EK is in the locking position VS.
  • This second switching sequence is only ended when the push pin ST of the second control contour SK2 returns the latch catch EV to the original starting position, the release FS of the latch EK, and thus the blocking of the latch EK is released.
  • the switch-on spring relaxes in order to switch off immediately afterwards with the switch-off pawl AK released in the first switching process to be able to effect the switch contacts.

Abstract

L'invention concerne un procédé pour la commande d'un module commutateur électrique, déplaçable entre une position </= rentré >/= et une position </= sorti >/= . Le module commutateur selon l'invention comprend des contacts de commutation d'interrupteurs à vide, ainsi qu'un élément sectionneur également mobile dans le module commutateur et comprenant des contacts de sectionnement qui peuvent être, selon les besoins, connectés à des contacts homologues correspondants et déconnectés de ces contacts à l'intérieur d'un tableau de distribution blindé, ainsi que des contacts à fiche et des contacts à fiche homologues dans la gamme des basses tensions. Selon l'invention, les contacts de commutation des interrupteurs à vide assistent les procédures de mise en circuit et de mise hors circuit, sous l'influence de commande d'un ressort d'enclenchement influencé par un loquet d'enclenchement (EK) et d'un ressort de déclenchement influencé par un loquet de déclenchement (AK), et des positions fonctionnelles importantes de l'élément sectionneur sont représentées par une </= position de marche >/= et par une </= position de sectionnement >/= . Dans une </= position de test >/= , située entre la </= position de marche >/= et la </= position de sectionnement >/= , de l'élément sectionneur, seuls les contacts de sectionnement sont déconnectés des contacts homologues ; dans la </= position de sectionnement >/= de l'élément sectionneur, les contacts à fiche sont également déconnectés des contacts à fiche homologues ; et, lors du passage du module commutateur de la </= position de sectionnement >/= à la position </= sorti >/= , le ressort d'enclenchement et le ressort de déclenchement sont forcés dans un état de détente. Un tel procédé est utilisé pour la commande de modules commutateurs amovibles dans des tableaux de distribution moyenne tension.
