TF series Intelligent demarcation switch controller (feeder terminal)

1.Outline
Intelligent demarcation switch controller (feeder terminal unit) of TF series is a distribution network automation terminal product developed for switches on medium voltage (10KV) columns. It is a new type of feeder remote terminal equipment based on the latest development requirements of distribution network automation, computer technology, digital signal processing technology and power grid fault detection technology. Its design, manufacture and testing fully adopt international IEC standards and relevant national standards. It can provide the data required for the operation control and management of the distribution system of the medium voltage 10KV feeder main station, and perform the control of the power distribution equipment given by the main station to achieve the functions of 10KV feeder automation. And it can realize all-round monitoring of cable dividing room, ring main unit, sub-section post, box transformer power distribution room, substation, water supply plant area, sewage plant area, gas and other places, and is widely used in various distribution places like substation, industrial and mining enterprises, urban power distribution, urban distribution network and rural distribution network.
This controller has “Three Teles” functions (telesignalization, telemetry and telecontrol), and also has the ability to get fault signals (interphase short circuit, one-phase ground, etc.). Combined with primary switch (circuit breaker, load switch, recloser, etc.), and cooperated with the power distribution (cell) master station network, it can achieve 10KV feeder fault diagnosis, fault section isolation, network reconstruction and normal power supply in non-faulty sections.
