- Product Description
-
The first-integrated SMS-FDR21 distribution network intelligent feeder terminal is mainly used in distribution network overhead lines to realize monitoring, fault judgment, resection, isolation of fault areas and restoration of power supply to non-fault areas of the feeder circuit column switch; Users need to use wireless, optical fiber and other communication methods to communicate with the power distribution master system for real-time communication.
Its technical features are:
1) Compatible with the requirements of one-time fusion, three-way, two-distance action, and two-distance standard type, and flexibly meet the occasions of off-site coincidence switch, line segmentation, line contact, user demarcation, etc. according to the configuration;
2) High-precision, wide-range sampling, conforming to the Comtrade 1999 standard for high-precision 128-point recording;
3) Small current single-phase ground fault, using transient algorithm, with ground fault local in-situ removal, line selection function and reclosing function, with the selection function based on centralized feeder automation;
4) Deepen the localized feeder automation application, compatible with recloser voltage time type, voltage and current time type, and adaptive integrated type.
5) Access the line loss measurement module to improve the level of management refinement.
6) Communication can be hard and soft encryption, built-in national network professional security chip.
7) The communication protocol is extended, and it has the function of configuring the national remote unified parameter.
8) Meet the requirements of the quality control system of the State Grid distribution equipment: type test, professional testing of distribution terminals, professional testing of one or two integrations, sample delivery before delivery, full inspection of arrival, on-site joint adjustment, and operation evaluation.
