Peti kawalan Recloser-Unit Terminal Feeder

Name: Peti kawalan Recloser-Unit Terminal Feeder
Brand: Zhuhai Gopower Smart Grid Co., LTD

Unit terminal feeder (FTU) adalah peranti kawalan suis HV baru kawalan kabinet kawalan yang dilengkapi dengan kedua-dua cip pensampelan berkelajuan tinggi DSP yang diimport dan cip lengan berprestasi tinggi, dan boleh cepat dan stabil menyelesaikan pemantauan pada suis.

Unit terminal jauh feeder industri oleh kamiSyarikat peralatan kuasa elektrikMempunyai fungsi seperti perlindungan, mengukur, mengawal, memantau, komunikasi, kawalan jauh, dan sebagainya dan mempunyai tahap integrasi yang tinggi, konfigurasi fleksibel, dan antara muka mesra pengguna. Kabinet kawalan elektrik digunakan secara meluas untuk sistem bekalan kuasa rangkaian berseri dan cincin.

Kotak kawalan elektrik kawalan luar FTU boleh membantuKabinet pengedaran elektrikSistem mengenal pasti kesilapan talian sementara dan kekal. Kotak kawalan luaran menghapuskan kesan kesilapan garis sementara secara automatik, mengasingkan segmen kesalahan kekal untuk mengelakkan kegagalan kuasa yang berpanjangan di kawasan yang besar, dan secara automatik memulihkan bekalan kuasa di kawasan bebas kesalahan, untuk merealisasikan automasi rangkaian pengedaran kuasa dengan cara yang ekonomik dan praktikal.

Recloser Control Box-feeder Remote Terminal Unit Characteristic Functions

Feeder terminal unit is small in size and large in quantity. FTU electrical control cabinet is equipped with a transmitter for direct AC sampling. It is resistant to high temperature and cold and is suitable for outdoor harsh environments.

Unlike the scada remote terminal unit, the amount of data collected by FTU electronic recloser controller box is small, the requirement of communication rate is low, and the requirement of reliability is high.

FTU outdoor recloser controller box can be manufactured by a high-performance single-chip microcomputer. In order to adapt to the harsh environment, industrial chips that can work at 75 ℃ shall be selected, and they shall be protected against lightning, rain and moisture through appropriate structural design.

Recloser Control Box-feeder Remote Terminal Unit Application

At present, feeder terminal units power recloser controller box as one popular type of distribution electrical box have been widely deployed in column switches, ring network cabinets, switching stations, power recloser controller boxes, and other places on the distribution network line to realize the "three remote" automation functions of remote signaling, telemetry and remote control of remote primary equipment.

As an information and data communication tool, a computer network provides a powerful communication means for industrial electrical cabinet and provides a reliable basis for realizing the networked control of distribution automation system devices. Fieldbus technology and GPRS wireless communication technology inject new vitality into the implementation of feed automation. Driven by network, communication and other information technologies, distribution automation is developing from spontaneous Island automation to unified and systematic comprehensive automation.
