The GS20 point heating system is based on a flexible architecture and can be adapted to any design requirement and any topology. This system can be centralized, decentralized, autonomous, or integrated into a centralized monitoring and control system.
GS20 System is powered from the Overhead contact line by pole-mounted substations or some other alternative power source. The system itself includes HMI workstation, SCADA subsystem, distribution cabinets, connection cabinets, electric heaters, and electrical cables for connection, control, and signaling. It is designed for easy handling and easy fault detection.
The system is designed so that tests can be performed to check and determine the failures of individual heaters.
The heaters are switched on, in normal operation, sequentially one after the other with a predetermined delay, in order to reduce the load on the electrical network.
The current state of the system can be monitored at the HMI workstation in the traffic office of the train dispatcher, and any irregularities are further highlighted. PLC controllers installed in each distribution cabinet communicate with the control system. The heater is switched on according to the relay command principle in order to reduce electric shocks and network load.
