The TEOL K3 control cabinet is designed for remote and local control of the overhead line disconnectors. The control and position monitoring of the disconnector is done through an existing connection between the disconnector and the control cabinet using a 3-wire line. For each disconnector, nominal and elevated control voltage values are individually configured. Similarly, for each controlled disconnector, current thresholds are declared for decoding the disconnector's states and for controlling the continuity of the control cables.
The TEOL K3 cabinet monitors the continuity of each control cable and signals a fault in case of a break. A graphical operator panel with a touchscreen, LED indicators, and buttons is used for local control of the cabinet. Each cabinet is standardly equipped with a dual object bus CAN-BUS/RS485 with PPM2 protocol, which allows remote control from a substation or section cabin. For direct remote control from the SCADA system, fiber optic modems/routers or GSM devices are typically used.
TEOL K3 cabinets are made as indoor or outdoor versions (typically mounted in the track gap). Along with the device, the user receives intuitive software for Windows-based computers, enabling easy configuration of the control cabinet, which is crucial during maintenance or line renovation work during transitional periods. Cabinet configuration can also be performed via the cabinet's controller.
