Highly Reliable Power Supply Systems
Design-assembled power supply system of an electrical interlocking of medium and large stations (PKSEP)
PKSEP is designed for power supply of relay or microprocessor-based interlocking devices of medium and large stations, at railway sections with any traction type.
Main functions
- supplying power from:
- two feeders of three-phase AC voltage 230/400 V with a dead-grounded neutral;
- a diesel-generator set (DGA);
- an accumulator battery (AB) with voltage 24 V;
- an AB with voltage 240 V;;
- distributing, converting, and recording electric power;
- three-level protection of power supply lines against atmospheric and switching overvoltages, short circuits, pulse overvoltages;
- quality monitoring for electric power;
- automatically switching a load;
- monitoring malfunction of contactors of both feeders and monitoring voltage which is present on a guaranteed three-phase current power supply bus.
System advantages
- Possibility to design a power supply system with the required parameters for a specific station;
- High survivability due to redundancy of main nodes;
- Built-in microprocessor-based system provides monitoring and diagnostics of power supply parameters and PKSEP ;
- Diagnostics results and archive data allow the following at any time: to monitor equipment state, to determine pre-failure conditions, failure mode of power supply devices.
Power supply system for electrical interlocking systems based on ShVRP-EC
It is intended for power supply of electrical interlocking devices of small and medium stations equipped with audio frequency or phase-sensitive track circuits, DC or AC electrical point machines.
System advantages
- Combination of functions of inputting, distributing, and converting panels;
- Three-level protection of power supply lines against atmospheric and switching overvoltages, short circuits, pulse overvoltages;
- Automated remote and on-site monitoring of power supply circuit state using a built-in microprocessor-based system;
- Maintenance of a deep archive of power supply parameters (archive data of one year);
- N+1 redundancy scheme with the hot swap function;
- Determination of equipment pre-failure conditions for “maintenance on condition”.
