Abstract

The utility model relates to a power communication device, in particular to an OPGW (optical power ground wire) optical fiber grounding device for a transformer substation. The device comprises an optical fiber splice closure arranged on a transmission line tower and an OPGW optical fiber led out from the optical fiber splice closure and connected with the transformer substation downwards along the transmission line tower. The OPGW optical fiber grounding device is characterized in that the OPGW optical fiber led out form the optical fiber splice closure is provided with a stranding cable clamp, one end of a grounding wire is connected with the stranding cable clamp, and the other end of the grounding wire is connected with the ground along the transmission line tower. As the stranding cable clamp is arranged on the led-out OPGW optical fiber on the transmission line tower of the transformer substation, the led-out OPGW optical fiber is connected with the grounding wire and is connected with the ground of the transformer substation, meanwhile, the grounding wire led out from the transmission line tower and the OPGW optical fiber are both arranged in a protection tube, so that the phenomenon that thunder and high tension electricity discharge the led-out optical cable of the transformer substation can be effectively avoided, the safe protection effect is exerted, and the OPGW optical fiber grounding device has the characteristics of simplicity in structure and convenience in operation.

Description

The OPGW of transformer station optical cable earthing device
Technical field
The utility model relates to the power communication device, particularly the OPGW of transformer station optical cable earthing device.
Background technology
The OPGW optical cable is also claimed OPGW, and it is to be placed on optical fiber in the ground wire of aerial high voltage power line, and in order to constitute the fiber optic communication network on the transmission line, this version has the ground wire and the dual-use function of communicating by letter concurrently, generally is called the OPGW optical cable.Cable splice closure generally is mounted on the angle steel at electric power line pole tower top at present; Must the OPGW optical cable be drawn down through electric power line pole tower in transformer station like this; Because big electric current, high voltage on the electric power line pole tower; Will produce electrostatic induction voltage to the OPGW optical cable under drawing on the electric power line pole tower, and thunder and lightning and high-tension electricity draw down to OPGW that optical cable produces electric discharge phenomena, cause many problems such as interruption of optical cables.
Summary of the invention
The purpose of the utility model is to overcome the defective that prior art exists, and provides a kind of and can prevent effectively that big electric current, high voltage and thunder and lightning on the electric power line pole tower from drawing the OPGW of the transformer station optical cable earthing device that following optical cable produces electrostatic induction voltage and electric discharge phenomena generation to the OPGW on the electric power line pole tower.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of OPGW of transformer station optical cable earthing device; Comprise cable splice closure and the introducing that is installed on the electric power line pole tower, the OPGW optical cable of drawing cable splice closure; It is characterized in that on the OPGW optical cable that cable splice closure is drawn, the Split Down wire clamp being installed, earth connection one end links to each other with the Split Down wire clamp, and the other end links to each other with the earth along electric power line pole tower.
The above-mentioned earth connection that links to each other with the earth along electric power line pole tower is installed in the pillar with the OPGW optical cable that links to each other with transformer station downwards along electric power line pole tower of being drawn by cable splice closure, and pillar is fixed on the electric power line pole tower.
Above-mentioned pillar is made up of the interior steel pipe of wearing pvc pipe.
The utility model is through on the OPGW optical cable downlead on transformer station's electric power line pole tower the Split Down wire clamp being installed; OPGW optical cable downlead is linked to each other with earth connection; And link with the transformer station the earth; To be installed in the pillar with the OPGW optical cable that links to each other with transformer station downwards along electric power line pole tower of drawing along the earth connection that electric power line pole tower links to each other with the earth simultaneously by cable splice closure; Prevented that effectively thunder and lightning and high-tension electricity from drawing optical cable electric discharge phenomena down to transformer station, played the security protection effect, had simple in structure, convenience operation.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; After the OPGW optical cable on the electric power line pole tower 71 is fixing through the insulation magnetic bottle, draw down; From draw down pillar, draw with cable splice closure 2 and is connected, another root of cable splice closure is to guide optical cable 5, draws along electric power line pole tower and assigns calculator room equipment in the transformer station.
On the OPGW of leading in cable connector box optical cable, Split Down wire clamp 3 is installed, earth connection 4 one ends link to each other with the Split Down wire clamp, and the other end links to each other with the earth along electric power line pole tower.The above-mentioned earth connection that links to each other with the earth along electric power line pole tower is installed in respectively in the pillar 6 with the OPGW optical cable that links to each other with transformer station downwards along electric power line pole tower of being drawn by cable splice closure; Wear the steel pipe of pvc pipe in pillar is, pillar is fixed on the electric power line pole tower.
