Application of components with high switching capacity, high dynamic resistance to short-circuit currents and long mechanical life provides high reliability of equipment. Compliance with International Standards DC Switchgears manufactured by PLUTON were successfully type-tested for compliance with International Electrotechnical Commission (IEC) standards in such test centers as IPH Institut (Berlin, Germany) and IEL (Warsaw, Poland) including internal arc testing. DC Switchgears meet international standards EN 50123-1:2003 /I EC 61992-1:2014, EN 50123-6: 2003+A1:2014 / IEC 61992-6:2014. • no...

Switchgear components are mounted in separate compartments. High and low voltage compartments are separated from each other. The separation ensures operation reliability, equipment servicing and operational safety. Switchgears are manufactured both for uni- and bilateral maintenance. 1. Automatics and Control Compartment: • B&R (Austria) 4PPC70 panel controller with visualization function, • traction network monitoring and protection system SMTN-3, • mechanisms control modules, • contactor relay devices. 2. High Speed Circuit Breaker Compartment: • DC high speed circuit breaker, • operating busbar...

High speed circuit breakers (Switzerland) are applied in DC Switchgear. Circuit breakers of this type have high breaking capacity and dynamic stability to short circuit currents. Main advantages of high speed circuit breakers: • mechanical simplicity; • automatic adjustment of contact tightness; • long lifetime; • inspection after 250 protection trippings; insulation material wiping under arc; stepless regulation of trip setting; compliance of all insulation materials with strict International and European environmental standards requirements; minimum tripping time; no need for often lubrication,...

EST, EDT disconnectors manufactured by Elpro (Germany) are applied for electric power circuit switching. Disconnectors have a unique crimp-type contact system design with double gap and wiping contacts, geared by a small-sized electric drive. Easy rolling out of trolley with circuit breaker and EDT double-pole disconnector is achieved due to disconnector unique design. Each pole has two rows of lamellae. They are separated from each other in off-line state, and allow connected busbars entering lamellae gaps smoothly, without mechanical withstand strength. When activating disconnector electric...

Switchgears are equipped with control, monitoring and protection system, which includes: • 4PPC70 panel controller with visualization function; • I/O modules series X20; • traction network monitoring and protection system SMTN-3. Main System Functions: • analysis of interlocks and implementation of traction substation control algorithms using microprocessor industrial controllers; • traction substation events logging for personnel actions and equipment operation analysing; • protection and recording of all network transient processes due to integrated traction network monitoring and protection...

Types of electronic protections (ANSI code): • instantaneous overcurrent (50); • overcurrent protection (76); • current rate of rise protection; • current increment directional protection; • overvoltage protection (59); • undervoltage protection (27); • thermal protection (49); • breaker failure (BF). SMTN-3 generates and stores the following records: • events log; • failures log; • emergency oscillograph records. Records are stored on nonvolatile solid data storage medium that guarantees data storage in case of devices power supply interruption, and high reliability. SMTN-3 system provides generation...
