Background technology
With the intelligentized development of power network, current most of transformer stations have been unattended operation transformer stations, but transformer station now
Ground wire configuration present situation be：
1st, each transformer station's storage (3 or 4) group ground wire, and being filled with a Special grounding wire storing unit or attached storage
Put, it is necessary to measure as (3 or 4) × N+N (N is transformer station's quantity).
2nd, each transformer station organizes ground wire with (3 or 4), stops power transmission operation in case of large-scale, frequent our station ground wire quantity is inadequate
With need to arrive other transformer stations and borrow, thus be easy for getting ground wire quantity wrong during power transmission after operation maintenance personnel operation, intuitively think
Be exactly 4 groups of ground wires of our station, exist forget also, it is wrong also, lose and even more serious leakage commutation as.
In summary, there are problems in the use in the prior art for transformer substation grounding wire, still lack effective solution
Certainly scheme.
The content of the invention
In order to solve the deficiencies in the prior art, positioned the invention provides a kind of transformer substation grounding wire for being easy to centralized management
Storing unit, the present invention can reduce transformer substation grounding wire deployment cost to a certain extent, and can effectively prevent that ground wire leakage from tearing open
With Loss, increase substantially power transformation operation maintenance personnel and stop the security that power transmission operational grounding line is used.
A kind of transformer substation grounding wire for being easy to centralized management positions storing unit, including for concentrating the cabinet of placement ground wire
Body, each ground wire is provided with corresponding GPS positioning device, and the ground wire is with GPS positioning device by being fixedly connected dress
Put connected, the fixed connection apparatus includes soft containment vessel and buckle, the soft containment vessel is used to be set with GPS location dress
Put, the buckle links together soft containment vessel with connecting wires, the GPS positioning device passes the location information of ground wire
Transport to mobile terminal, mobile terminal is provided with the alignment system matched with GPS positioning device and achieved a butt joint the precisely fixed of ground wire
Position, real-time tracking.
Further, the GPS positioning device miniature is exempted to install GPS location using what is generally used on automobile
Device.
Further, indicator lamp, switch and charge port are provided with the GPS positioning device, the indicator lamp is set
Above GPS positioning device housing, the switch and charge port are arranged at a side of GPS positioning device housing, institute
State and switch the position of corresponding housing and be provided with the buckle-type lid being connected with GPS positioning device housing.
Further, the monitor supervision platform is additionally operable to the electricity of monitoring GPS positioner and shown in real time.
Further, it is described to be used to concentrate the cabinet for being provided with hinge pin rotation link on the cabinet for placing ground wire
Door, the cabinet door is provided with the mosaic glass for being easy to observe concrete condition in cabinet.
Further, the storage for being used to concentrate the frame front face for the cabinet for placing ground wire to be provided with mobile terminal
Region.
