Used to protect, control, measure and monitor medium voltage power grids
The REF 543 feeder terminal can be used in combination with a variety of switching devices, including single-bus, dual-bus and dual-machine systems.
The RET543AM240AAAA protection function also supports various types of networks, such as neutral ungrounded networks, arc suppression coil grounded networks, and partially grounded networks. Its application scope also covers the protection and control of medium-sized three-phase asynchronous motors and reactive power compensation shunt capacitor banks. In addition to protection, measurement, control, condition monitoring and general functions, the REF 543 feeder terminal provides a large number of PLC functions, which allows the multiple automation and sequential logic control functions required for substation automation to be integrated in a single unit.
Data communication supports the following communication standards: SPA bus protocol, LON bus protocol, IEC 60870-5-103 protocol, IEC 61850 supported by SPA-ZC 400, Profitbus DPV1 protocol supported by SPA-ZC 302, DNP 3.0 and Modbus for upper devices Communication protocol. In addition, the LON communication protocol combined with PLC functionality reduces the need for hard wiring between feeder terminals.
Major advantage
A large selection of protection features
PLC programmable features provide high flexibility to meet a wide range of applications
25 switching inputs and 18 outlet relays
Flexible connectivity for all communication needs
How it works:
RET543AM240AAAA Under normal operation, the feeder terminal will monitor the operating parameters of the feed line in real time and send these parameters to the distribution station through the CAN bus.
The feeder terminal can also work in the monitoring state and periodically send relevant parameters to the distribution station.
When receiving the command of the distribution station, the feeder terminal will perform the corresponding operations, such as the closing and opening of the line switch.
Features and requirements:
The RET543AM240AAAA feeder terminal should be able to adapt to the harsher operating environment, be able to work normally in the temperature range of -30 ° C to +60 ° C, and have good moisture, rain and corrosion protection measures.
Because the feeder terminal is usually installed on the power line post or in the combined distribution cabinet, it is required to be small in size, easy to install, and power consumption should be as small as possible.
The feeder terminal also needs to have a high anti-interference ability to withstand high voltage, high current, lightning and other interference.
Application scenario:
Feeder terminals are mainly used in the monitoring of overhead distribution lines and cable circuit cabinets in power systems.
By monitoring and reporting the running parameters of the feed line in real time, and executing the command of the distribution station, it realizes the optimal management and fault handling of the distribution network.
