Description

Technical Field

[0001] The present invention relates to the field of distribution terminals, and particularly to an FTU wiring device for improving the scheduling fault handling efficiency.

Background Art

[0002] Due to the rapid development of the economy, the urban power load has increased rapidly, increasing the pressure on the power transmission network to provide a stable power supply, and the user's requirements for the reliability of power supply and power quality have also increased, which means that more and more distribution automation terminals are being applied. In the distribution network construction project, each ring network cabinet or feeder from the distribution network requires a distribution automation terminal. Currently, the three remote signal circuits between the substation terminal and the switch 200 on the market are point-to-point access methods directly accessing the terminal row of the terminal equipment from a single wire. When it is necessary to control six switches 200 with one terminal, about 200 wires need to be wired between the switch 200 and the substation terminal, which is time-consuming and costly in terms of construction period and labor cost. When a substation terminal fails, it takes a long time to disassemble the substation terminal for circuit overhaul and equipment replacement, resulting in a long power outage time and large economic losses. Furthermore, maintenance personnel require specialized and strict training, indirectly leading to an increase in construction costs and maintenance costs.
