Description

A kind of fiber cable cross connection box of seat isolated at the end
Technical field
The utility model relates to a kind of fiber cable cross connection box of seat isolated at the end.
Background technology
Along with the widespread use of electric system composite ground wire optical cable (OPGW), transformer station needs a large amount of OPGW introducing, connection device.Fiber cable cross connection box commonly used is that remaining cable frame, connector box are arranged in the metal box that lands at present, and OPGW optical cable and the metal free optical fiber cable reel that it is unnecessary is tied on cable frame more than optical cable, the OPGW optical cable is connected in cable splice closure with metal free optical fiber cable, metal box is installed on concrete foundation, as shown in Figure 1.
There is subject matter in present mounting means: because the optical cable joining box foundation is connected with grounding body in transformer station, when needs are measured substation grounding resistance, can not thoroughly disconnect OPGW ground connection in transformer station, affect the accurate measurement of substation grounding resistance.
The utility model content
In order to address the above problem, the purpose of this utility model has been to provide a kind of fiber cable cross connection box of seat isolated at the end, and it is simple in structure, can thoroughly the OPGW optical cable be separated with ground wire in transformer station, and it is simple to operate, safe and reliable.
The utility model is the purpose that reaches above-mentioned, and the utility model adopts following technical scheme:
A kind of fiber cable cross connection box of seat isolated at the end, comprise the handing-over casing, be separately installed with the remaining cable frame of cable splice closure, optical cable in described handing-over casing, ground connection tandem row be installed in described handing-over casing, described ground connection tandem row respectively more than cable splice closure and optical cable cable bridge joint ground wire be connected; Described ground connection tandem row is connected with grounding connection line one end, and the other end of grounding connection line is connected with ground connection; Described handing-over casing is connected with supporting insulator base by support insulator, and described supporting insulator base is connected with ground.
Described ground connection tandem row is connected with ground connection by a unique grounding connection line.
The beneficial effects of the utility model are: the utility model provides a kind of fiber cable cross connection box of seat isolated at the end, and it is simple in structure, can thoroughly the OPGW optical cable be separated with ground wire in transformer station, and it is simple to operate, safe and reliable.

Embodiment
Embodiment 1
As shown in Figure 2, the present embodiment provides a kind of fiber cable cross connection box of seat isolated at the end, comprise handing-over casing 2, OPGW optical cable 5, metal free optical fiber cable 6, be separately installed with cable splice closure 3, the remaining cable frame 4 of optical cable in described handing-over casing 2, described OPGW optical cable 5 is connected with cable splice closure 3 by the remaining cable frame 4 of optical cable respectively with metal free optical fiber cable 6, ground connection tandem row 10 is installed in described handing-over casing 2, described ground connection tandem row 10 respectively more than OPGW optical cable 5, cable splice closure 3 and optical cable cable frame 4 ground wires be connected; Described ground connection tandem row 10 is connected with grounding connection line 12 1 ends, and the other end of grounding connection line 12 is connected with ground connection 7; Described handing-over casing 2 is connected with supporting insulator base 9 by support insulator 8, and described supporting insulator base 9 is connected with ground 1.Described ground connection tandem row 10 is connected with ground connection 7 by a unique grounding connection line 12.The outer insulation tube 11 that is socketed with of described OPGW optical cable 5, the outer coating steel pipe 13 that is socketed with of insulation tube 11.
As shown in Figure 3, OPGW optical cable 5 draws from outlet structure to be worn insulation tube 11 after lower and enters in handing-over casing 2, and insulation tube 11 use coating steel pipes 13 are protected.After OPGW optical cable 5 enters handing-over casing 2, elder generation's coil on cable frame 4 more than optical cable, then cause cable splice closure 3.In standing, metal free optical fiber cable 6 is cable splice closure 3 in and 5 weldings of OPGW optical cable, through being connected to machine room after cable frame 4 coils more than optical cable.The metal part of OPGW optical cable 5 is connected with ground connection tandem row 10.By grounding connection line 12, the grounding connection line 12 of ground connection tandem row 10 and substation grounding 7 joins.OPGW optical cable 5 and framework keep only having the framework top some to be connected, and the surface of contact of framework middle part drop wire clip and OPGW optical cable 5 insulate.
When measuring the stake resistance of transformer station, only need to remove the grounding connection terminal 14 on OPGW optical cable 5 and framework, OPGW optical cable 5 and substation grounding are disconnected fully, eliminate the outer steel tower ground connection in station to the impact of substation grounding resistance measurement.Transformer station's main grounding grid resistance measurement is complete, answers the ground connection of immediate recovery cross-connecting box and outlet structure.
The fiber cable cross connection box of the seat a kind of isolated at the end of the present embodiment manufacturing, it is simple in structure, can thoroughly the OPGW optical cable be separated with ground wire in transformer station, and it is simple to operate, safe and reliable.
