Recloser Control Box-Feeder Terminal Unit
Recloser Control Box-Feeder Terminal Unit
The feeder terminal unit(FTU) is a new HV switch control device of control cabinet enclosures equipped with both the imported DSP high-speed sampling chips and the high-performance ARM chips, and can fast and stably finish the monitoring on the switch.
Industrial feeder remote terminal unitby our electric power equipment company has such functions as the protection, measuring, controlling, monitoring, communication, remote control, and so on and features high integration level, flexible configuration, and user-friendly interface. Electrical control cabinetare widely applied to the radiant and ring network power supply systems.
FTU outdoor control electrical control box can help the electrical distribution cabinet systems identify transient and permanent line faults. Outdoor control box eliminate the impact of transient line faults automatically, isolate the permanent fault segments to avoid prolonged power failure in a large area, and automatically recover the power supply in fault-free areas, so as to realize the automation of power distribution network in an economical and practical way.

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.
Zhuhai GopowerSmart Grid Co., Ltd. was founded in 1998. It is one of the earliest high-tech electric power equipment ltd engaged in R&D and production of (12KV-40.5kV) medium-voltage transmission and distribution intelligent control equipment in China. It is one of the initiators and members of the Zhuhai Smart Grid Alliance. After 15 years of painstaking exploration and development.
