Description
Battery backup system for railway signalling
Railway modernization, now integrating digital control and additional safety functionalities, requires new generation of equipment for signalling – with monitoring and independent battery backup. Part of the modernization will require to maintain and upgrade existing systems without any traffic disruption, demanding high flexibility in the power solution deployed on track side.
To achieve this goal, Powerbox developed a modular concept, making it easy to adjust to different configurations. On installed based, power modules and monitoring units can be substituted by the new generation fitting into the existing chassis. In case expansion or high level of upgrade, requiring very short time to operation, the new modular racks can be customized to specific configuration to power new signalling equipment such as optical fibre transmission.
Combining high efficiency switching with an optimized topology integrating control and monitoring, the new generation of Track Side Power System for signalling offers a significant cost saving compared to conventional technology. The platform includes a range of products which can be quickly modified to meet specific demand such as adaptive voltage and power to the length of the track and to the number of systems powered on the signalling network.
The power supplies units are enclosed in metal cases with a 230Vac input, delivering regulated voltage to the signalling equipment (ac and dc). The system also incorporates a power supply backup system based around SLA batteries.
The entire system is intended to be installed, maintained, repaired and eventually decommissioned with the minimum possible time spent track side. Any part/company likely to fail during the life of the system must have provision to be quickly and easily repaired or replaced. Our units are plug and play components so they can be changed very easily and quickly.
