The infrastructures in the transport sector are becoming more and more technologically advanced and must guarantee excellent performance and a high level of reliability and safety for passengers and workers. The need to ensure operational continuity in the provided service is an essential element especially for mass transport such as railways and urban public transport.
In recent years, more and more countries are giving more importance to sustainable mobility, investing in public transport and encouraging citizens to reduce the use of the most polluting cars. In this context, AEC aligns itself with the greater demand for sustainable mobility as uninterruptible power supplies play a fundamental role for companies that must offer citizens an impeccable service and avoid interruptions and therefore delays. AEC's three-phase online UPSs offer low voltage power grid solutions that ensure maximum performance for even critical applications , such as railways.
Railway stations and underground and bus stops are places that require high energy performance to guarantee the safety of passengers and operators first and to ensure maximum availability of electricity. In this context, three-phase online UPSs play a fundamental role in preventing service interruptions and protecting even the most critical applications.
The electrical substations are systems that transmit and control the electrical energy for the traction of trains. They are usually located near a station or the railway network and a continuous power is essential to allow the system to transform and convert the electricity for the train engines.
The remote control centers are a computerized system that monitors and manages the traffic of the trains and therefore their correct and constant functioning is essential for the safety of people and to communicate promptly to passengers any changes or delays.
The overhead contact lines and catenaries of the railway lines transmit electricity to trains and to all electric public transport such as trams and trolley buses. Three-phase online UPSs are used to protect these power networks and to ensure maximum energy availability.
A constant power supply is necessary for all signaling systems that are used to make roads and stations safer, such as traffic lights and signage systems along the tracks. Even in these contexts, online UPS can significantly reduce the inconvenience that a sudden blackout could cause in particularly crowded places.
As in all public places where crowding is expected, also in stations it is necessary by law to adopt electric rescuers for safety and emergency systems, better known as CPSS - Central Power Supply System. The EN 50171 standard provides for the obligation to use CPSS as they represent an essential safeguard to protect the health and safety of people and rescuers in case of criticality.
