Definitions

  • the device 30 may include a controller comprising microprocessor, microcontroller, PLC or other programmable device (not shown) for controlling the operation of the spring 50.
  • the controller may monitor the output of the voltage monitor, determine when the fuse 34 is blown and, after an appropriate delay, cause the spring 50 to be released.
  • the contact of the switching mechanism connecting to fuse 34 must be capable of carrying fault current, but is only required to be load make or break.
  • the contact connecting to fuse 36 e.g. the contacts 42, 44, 46
  • the contact 142 forms part of a switch device 143.
  • the switch device 143 also includes fixed contacts 144, 146 which are cooperable with the movable contact 142 to make or break an electrical circuit and, in particular, to make or break the electrical connection between the second end 139 of the fuse 136 and the second main contact 140.
  • the contacts 144, 146 are spaced-apart and arranged to receive the movable contact 142 therebetween such that the movable contact 142 makes an electrical connection between the fixed contacts 144, 146.
  • the movable contact 142 is wedge-shaped such that its leading end (in the direction of movement towards the fixed contacts) is narrower in transverse cross-section than its trailing end.
  • the gap 145 between the fixed contacts 144, 146 is correspondingly wedge-shaped.
  • the contact 142 and gap 145 may take any other suitable shape and, typically, are substantially rectangular in transverse cross-section.
  • the preferred device 130 is also capable of reporting this condition to a remote location as above.

Claims (9)

  1. Elektrische Sicherungsvorrichtung (130), umfassend einen ersten und einen zweiten elektrischen Hauptkontakt (138, 140), zwischen denen eine Primärsicherung (134) elektrisch anschließbar ist; Mittel zum Aufnehmen einer Sekundärsicherung (136), so dass ein Ende (137) der genannten zweiten Sicherung elektrisch mit dem genannten ersten Hauptkontakt verbunden ist; Mittel (143) zum wählbaren Verbinden des anderen Endes (139) der genannten Sekundärsicherung mit dem genannten zweiten Hauptkontakt; Mittel zum Erkennen eines Ausfalls der genannten Primärsicherung und zum Bewirken, dass das genannte Verbindungsmittel als Reaktion auf einen erkannten Ausfall der Primärsicherung das genannte andere Ende der genannten Sekundärsicherung mit dem genannten zweiten Hauptkontakt verbindet, dadurch gekennzeichnet, dass eine Betätigungseinrichtung (155) vorgesehen ist, um das genannte Verbindungsmittel in einen geschlossenen Zustand zu betätigen, in dem das genannte andere Ende der Sekundärsicherung in Gebrauch mit dem genannten zweiten Hauptkontakt verbunden ist, und wobei die genannte Betätigungseinrichtung von einem entfernbaren Teil (130A) der Vorrichtung gehalten wird.
  2. Vorrichtung nach Anspruch 1, wobei ein Halter (171) für die genannte Primärsicherung (134) an einem entfernbaren Teil der Vorrichtung vorgesehen ist.
  3. Vorrichtung nach Anspruch 1 oder 2, wobei die genannte Betätigungseinrichtung (155) und der genannte Primärsicherungshalter (171) beide an dem selben entfernbaren Teil der Vorrichtung vorgesehen sind.
  4. Vorrichtung nach einem der Ansprüche 1 bis 3, wobei die genannte Betätigungseinrichtung dazu angepasst ist, zur Betätigung bereitgemacht werden zu können, vorzugsweise manuell bereitgemacht zu werden, wenn sie aus der Vorrichtung entfernt ist.
  5. Vorrichtung nach einem der vorangehenden Ansprüche, wobei das genannte Verbindungsmittel einen beweglichen Kontakt (142) umfasst, der mit einem ersten und einem zweiten festen Kontakt (144, 146) zusammenwirkbar ist, wobei der genannte bewegliche Kontakt zwischen einem offenen Zustand, in dem der genannte erste und der genannte zweite feste Kontakt elektrisch voneinander getrennt sind, und einem geschlossenen Zustand, in dem der genannte erste und der genannte zweite feste Kontakt elektrisch miteinander verbunden sind, beweglich ist, wobei einer der genannten festen Kontakte in Gebrauch mit dem genannten anderen Ende der genannten Sekundärsicherung verbunden ist, und der andere der genannten festen Kontakte mit dem genannten zweiten Hauptkontakt verbunden ist.
  6. Vorrichtung nach Anspruch 5 wenn abhängig von einem der Ansprüche 1 bis 4, wobei die genannte Betätigungseinrichtung, wenn sie in die Vorrichtung eingeschoben wird, dazu angeordnet ist, den genannten beweglichen Kontakt in seinen geschlossenen Zustand zu betätigen.
  7. Vorrichtung nach Anspruch 6, weiter umfassend eine Station (186) zum entfernbaren Aufnehmen der genannten Betätigungseinrichtung, wobei ein Teil der genannten Station durch eine an den genannten beweglichen Kontakt gekoppelte Auflagefläche (188) definiert ist, wobei die Betätigungseinrichtung ein ausfahrbares, vorzugsweise linear ausfahrbares Betätigungselement (157) umfasst, das dazu angeordnet ist, auf die genannte Auflagefläche zu wirken, wenn sich die Betätigungseinrichtung in der Station befindet.
  8. Vorrichtung nach Anspruch 7, wobei die genannte Station Mittel (161) zum Aktivieren der genannten Betätigungseinrichtung umfasst, wobei das genannte Aktivierungsmittel dazu angeordnet ist, lösbar mit der genannten Betätigungseinrichtung zu koppeln.
  9. Vorrichtung nach einem der vorangehenden Ansprüche, wobei die genannten Enden der Primärsicherung oder der Primärsicherungshalter lösbar mit jeweiligen Hauptkontakten eingreifbar sind.
