The SO-54SR-101-REK recloser controller is designed for complex support of the RC 27 or GVR overhead automatic circuit-breaker. It realizes measurement, protection, control, telemetry, automation and recording functions. The controller has a dedicated panel casing and is installed in a control unit designed for the RC 27 circuit-breaker. The entire control unit comprises:
- SO-54SR-101-REK (recloser controller with protection functions)
- IPR-002 (measurement interface)
- MSG-610 or MSG-411 (GPRS-APN communication module)
- 24V DC accumulator with a power supply and charging unit
- local control buttons
- LED indication of a current state of a circuit
- cam switches (operation mode selection, enabling-disabling AR, work on line)
- installation circuit-breaker
- clamp terminals
- heater with temperature control
The SO-54SR-101-REK recloser controllers is equipped with a dispatcher’s panel consisting a graphic terminal with a touch screen (LCD), a module with 8 signaling LEDs and an ON/OFF button. Additionally, the panel may be equipped with a key switch for local and remote operation mode.
The communication with the controller may be performed both by means of the dispatcher’s panel and a dedicated computer program used to configure protection functions, preview settings and states of inputs and outputs and read measurements. The communication may be realized locally or remotely thanks to the dedicated software.
The SO-54SR-101-REK recloser controller has also software interlocks which eliminate the possibility of remote or local controlling in the case of a collision in issued commands, ensuring safety of operation in this way.
The internal event log stored in the controller memory enables to define in the off-line mode outage causes and controller reactions and cooperating remaining external devices with 1ms precision. The multi-channel disturbance recorded (being a part of the software) enables to analyze emergency states and their causes, what increases operational reliability of an entire system. [-]
