YHK61 three remote type shielded vertical DTU

Back to superior

Product Name: YHK61 Three-Remote-Shading Vertical DTU

product description

The cable “three remote” terminal is the station terminal. The station terminal is a power distribution terminal installed in the distribution network switch station, distribution room, ring network unit, box-type substation, etc. It can cooperate with the distribution network automation main station and sub-station system to realize the collection, control and protection functions of multiple lines of electricity, and can quickly locate fault areas, isolate and restore power to non-fault areas to improve power supply reliability. YHK series distribution network automation device uses high-performance 32-bit microprocessor as the hardware development platform and embedded real-time operating system as the software development platform. The product has the characteristics of stability and reliability, high performance, high accuracy, low cost, and easy installation.

Product Features

Three remote functions : telemetry (including DC), remote signaling, remote control;
Fault detection and alarm, fault discrimination functions : over current, overload, load overload limit, etc .;
Remote / local operation : The remote / local closing and closing operations are mutually blocked, and the control exit is controlled by the soft and hard pressure plates.
Fault reset function : automatic reset, manual reset, remote remote reset; power function: dual power switch, automatically switch to the backup power supply when AC power failure, and realize automatic management of backup power (battery activation, alarm, Protective function;
Communication function : multiple network ports and serial ports, support multiple communication protocols, and can communicate with both uplink and downlink;
Status indication : there are obvious local status indication signals such as operation, communication, and line failure;
Extended functions : three-phase three-segment protection, zero-sequence current (voltage) protection, in-place recloser FA logic function, intelligent distributed FA function (master-slave / peer-to-peer).
