Switch Point Heating Control Cabinet

Details: Switch Point Heating Control Cabinet

Switch Point Heating Control Cabinet, type: EK URO-1 serves for:

Low voltage power distribution to local railway switch heating power distrubution box type: EK POG-1
Main power bus short circuit protection
Selective short circuit protection of outgoing parallel power bus
Network nominal parameters measurement (U,I), power consumption (kWh), heater operation time counting
Permanent isolation resistance control of radial low voltage power network, including transforme secondary with two stage activation (lowered isolation level and low level isolation – ground fault)
Group and individual control of outogoing power bus in powerless state
Prevention of power switching on in case of ground fault
Current measurement and status indication of switch heater groups (particular current value of switch heater group, ground fault or line break of particular heater in group)
Local heating control, network electrical parameters status indication as well as of group heater status indication
Automatic heating switching depending on air temperature and precipitations
Automatic power switching-off in case of ground fault nad prevetion of opwer switching on
Microcontroller based operation
Automatic system monitoring over SCADA

Safety ring heating system networking over RS485 conveter and fiber optic cabling.
