Our own vision of DC switchgear allowed PLUTON experts to create a conceptually new design characterized by compact size, maintainability, operational reliability and personnel safety.
AFB arc-free ultra high-speed circuit breaker with improved operational characteristics is applied in DC switchgear:
EST, EDT disconnectors manufactured by Elpro (Germany) are applied for electric power circuit switching.
Applied disconnectors have a unique crimp-type contact system design with double gap and wiping contacts, geared by a small-sized servo drive.
Disconnectors are classified as maintenance-free components, with 30 000 cycles (or 20 years) before maintenance.
Disconnectors are equipped with noiseless low consumption electric drive, capacity 18 W. Application of electric drives controlled with automation system reduces risk of disconnectors and bearing insulation damage in case of false staff operation with undue exertion.
Switchgear is provided with microprocessor control and diagnostics system based on B&R (Austria) industrial controllers 4PPC70, which include visualization panel with color LCD display.
Industrial controller 4PPC70 has significant calculation performance, high productivity and compact size.
Main functions of 4РРС70 industrial controller:
Switchgear components are mounted in separate compartments:
High- and low-voltage circuits are separated from each other providing operational reliability, equipment maintenance and operation safety.
Safe access to cables
Safe access to cables with operating busbar under voltage is provided due to isolated separation of busbar compartment into three physically independent of each other compartments (auxiliary busbar compartment — main busbar compartment — feeder cables busbar compartment)
Withdrawable unit as a part of switchgear allows quick and safe inspection/maintenance of power switching device in maintenance position. Operation and control position allow visual remote monitoring of power circuit opening.
Uni- or bilateral maintenance provides easy access to all components of the cubicle and maintenance safety.
