CWBC-03 automatic feeder terminal (hood FTU), suitable for distribution networks with voltage levels of 10kV and above. It can be applied to the distribution network feeder automation system with double-ended power supply, open-loop or closed-loop operation. CWBC-03 is a "three remote" type distribution automation feeder terminal. By collecting the feeder current, voltage and state quantity, it can complete the local and remote monitoring, control and fault detection functions of the switchgear on the column.
Features
Flexible configuration; compatible with primary and secondary integration, three-remote, two-remote action type, and two-remote standard type requirements, and can flexibly meet the needs of off-site reclosers, line segmentation, line contact, user demarcation and other occasions according to the configuration;
High-precision sampling; optional electromagnetic transformers and electronic sensors, which meet the requirements of metering, measurement, and protection at the same time, and achieve high-precision 128-point wave recording in line with Comtrade 1999 standards;
Fault removal; small current single-phase ground fault, using transient algorithm, with ground fault local removal, line selection function and reclosing function, with section selection function based on centralized feeder automation;
Strong compatibility; deepen the automatic application of local feeder, compatible with recloser type voltage time type, voltage current time type, self-adaptive integrated type;
Refined management; access the line loss metering module, forward power data such as forward and reverse active power, four-quadrant reactive power, upload daily frozen power files, power reverse power frozen value files, and realize line loss in the same period system to improve the level of refined management;
Data security; communication encryption, built-in State Grid professional security chip, to achieve communication channel protection, identity authentication, business data encryption;
Remote management; communication protocol expansion, with the national grid unified remote transmission parameter configuration function, remote control recording, log, wave recording, electricity and other file upload functions;
High degree of standardization; meet the requirements of the State Grid power distribution equipment quality control system: type test, professional testing of power distribution terminals, professional testing of primary and secondary integration, sample delivery before supply, full inspection on arrival, on-site joint debugging, and operation evaluation. Primary and secondary fusion feeder terminal FTU, in line with State Grid's primary and secondary fusion technology:
