Generator circuit breaker cubicle type D-17G

Home page/Offer/Products/MV switchgear in air insulation/Generator circuit breaker cubicle type D-17G

Purpose

Generator circuit breaker cubicle D-17G type, air-insulated, is dedicated to lead out generator’s power with nominal voltage of 12 kV and 17,5 kV.

Application

  • power generators leads in power stations, heat & power plants,
  • in electricity distribution networks and industrial plants.

General characteristics

  • indoor, single unit, air-insulated,
  • free standing (maintenance gangway),
  • metal enclosed,
  • internal arc resistant,
  • separate compartment of  auxiliary circuits,
  • perfect quality of paint coating,
  • modern design solusions ensure maintenance-free operation.

Application control and supervision systems allows generally maintenance-free operation of the generator circuit breaker cubicle with motor drives (operating of disconnector and earthing switch).We offer a series of applications of the generator’s circuit breaker cubicle. The presented design solutions are exemplary and thanks to a very experienced construction department, we can modify and execute them depending on the needs and requirements which is important in the case of retrofitting existing installations.For each generator’s circuit breaker cubicles D-17G, declaration of conformation is issued.

Features

  • small overall dimensions and simple construction,
  • switching operations with closed door, with ipreserving IP 4X degree of protection,
  • easy maintenance,
  • guarante the correct order of awitching operations trought a system of interlock,
  • safety of operating staff in case of internal arc,
  • stable construction for easy transport and installation,
  • possibility of quick disassembling of a circuit breaker mounted on the truck,
  • easy access to flexible connector,
  • application of vacuum circuit breakers type VAH, 3AK7,
  • motor drives of the earthing and disconnector allow remote control (open / close),
  • possibility to choose between remote or local control,
  • minimum requirements for the inspection and maintenance,
  • environmentally-friendly production,
  • professional service of the manufacturer.
