Abstract
OPGW optical cable is at the ground structure of transformer station: to an open air station, framework pillar top and bottom be respectively provided be electrically connected with framework pillar, block and the OPGW that centre has hole reserves earth terminal, each earth terminal area of plane should be not less than 3000mm
2, OPGW reserves an earth terminal bolt type aluminum device clamp with bolts, and bolt type aluminum device clamp connects OPGW optical cable ground line end; To indoor station, along the zinc-plated band iron of inlet wire side parapet horizontal laying one, position is from terrace 300mm, from wall 50mm level, and be reserved with two holes, in slave station, equipment ground separately draws the zinc-plated band iron that on two zinc-plated band irons, roof and inlet wire side parapet lay and welds in addition, forms grounded screen, a preformed hole bolt type aluminum device clamp with bolts of the zinc-plated band iron of horizontal laying, bolt type aluminum device clamp connects the ground wire end of OPGW optical cable.This OPGW optical cable is at the ground structure of transformer station, and unified and standard and easy construction, the more important thing is and ensure that the good and stake resistance of ground connection contact meets the demands.
Description
Technical field
The utility model relates to a kind of ground structure of OPGW optical cable, especially relates to the ground structure of a kind of OPGW optical cable in transformer station.
Background technology
Optical fiber is placed in the ground wire of aerial high voltage power line, and in order to form the fiber optic communication network on transmission line of electricity, this version has ground wire and the dual-use function that communicates concurrently, is generally called OPGW optical cable.Existing transformer station, when OPGW accesses transformer substation framework, also exists the too small and loose contact phenomenon of OPGW is not connected with transformer substation framework grounded screen or OPGW is connected with transformer substation framework grounded screen connection area.
Utility model content
Technical problem to be solved in the utility model, is just to provide the ground structure of a kind of unified and standard and OPGW optical cable of easy construction in transformer station.
Solve the problems of the technologies described above, the utility model by the following technical solutions.
OPGW optical cable is at a ground structure for transformer station, and described transformer station is divided into open air station and indoor station, and open air station is provided with conduction and the framework pillar of ground connection, and the roof at indoor station is provided with parapet, it is characterized in that:
To open air station, framework pillar top and bottom be respectively provided be electrically connected with framework pillar, block and the OPGW that centre has hole reserves earth terminal, each earth terminal area of plane should be not less than 3000mm
2, OPGW reserves an earth terminal bolt type aluminum device clamp with bolts, and bolt type aluminum device clamp connects OPGW optical cable ground line end;
To indoor station, along the zinc-plated band iron of inlet wire side parapet horizontal laying one, position is from terrace 300mm, from wall 50mm level, and be reserved with two Φ 17.5m holes, in slave station, equipment ground separately draws the upper roof of two zinc-plated band irons (not shown in FIG.) and welds with the zinc-plated band iron that inlet wire side parapet lays in addition, formation grounded screen, a preformed hole bolt type aluminum device clamp with bolts of the zinc-plated band iron of horizontal laying, bolt type aluminum device clamp connects the ground wire end of OPGW optical cable.
Beneficial effect: OPGW optical cable of the present utility model is at the ground structure of transformer station, and unified and standard and easy construction, the more important thing is and ensure that the good and stake resistance of ground connection contact meets the demands.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As shown in Figures 1 to 5, OPGW optical cable of the present utility model is in the ground structure embodiment of transformer station, and transformer station is divided into open air station and indoor station, and open air station is provided with conduction and the framework pillar of ground connection, and the roof at indoor station is provided with parapet.
To open air station, the top of framework pillar 4 and bottom be respectively provided be electrically connected with framework pillar, block and the OPGW that centre has φ 17.5 hole reserves earth terminal 3, each earth terminal area of plane should be not less than 3000mm
2, OPGW reserves earth terminal and adopts M16 × 40 bolt to connect a bolt type aluminum device clamp 2 (model SL-2), and bolt type aluminum device clamp connects OPGW optical cable ground line end 1;
To indoor station, when inlet wire maked somebody a mere figurehead by OPGW optical cable 5, along the zinc-plated band iron 6 of inlet wire side parapet horizontal laying one 60 × 8mm, position is from terrace 300mm, from wall 50mm level, and be reserved with Φ 17.5m hole, in slave station, equipment ground separately draws the upper roof of two zinc-plated band irons (not shown in FIG.) and welds with the zinc-plated band iron that inlet wire side parapet lays in addition, form grounded screen, the preformed hole of the zinc-plated band iron of horizontal laying adopts M16 × 40 bolt to connect a bolt type aluminum device clamp, and bolt type aluminum device clamp connects the ground wire end of OPGW optical cable.
