Abstract

The utility model discloses an optical power ground wire (OPGW) pull-in optical cable safety grounding fixing assembly, which comprises an over cable rack I and an over cable rack II. The over cable rack I is transversely arranged and the over cable rack II is vertically arranged. The two over cable racks are crossed and fixed to form a cross-shaped over cable coiling unit. At least one connecting mechanism I for being fixed to a truss bar is arranged on the over cable rack II. The fixing assembly also comprises an optical cable splice tray. A connecting mechanism II for being fixed to a truss piece is arranged on the optical cable splice tray. The optical cable splice tray is reliably grounded through a grounding drainage piece. An optical cable led out of the optical cable splice tray is coiled up through the cross-shaped over cable coiling unit. The fixing assembly also comprises a plurality of fixing clamps for fixing an optical cable onto the truss piece. Due to the adoption of the above structure of the utility model, an OPGW can be conveniently introduced into the door-shaped truss of a transformer station to be grounded, so that the damage of the optical cable due to a large current flowing through the OPGW is effectively prevented. Meanwhile, the grounding point can be conveniently disconnected so as not to influence the grounding test of the transformer station.

Description

The OPGW optical cable safety ground fixation kit that enters the station

Technical field

The utility model relates to the enter the station fixation kit of optical cable safety ground of a kind of OPGW of being used for.

Therefore, be necessary to work out a kind of OPGW optical cable safety ground fixation kit that enters the station, the safety ground of the optical cable of can realizing entering the station has convenient installation simultaneously.

Summary of the invention

In view of this, the purpose of the utility model provide a kind ofly be easy to use, safe and reliable OPGW enters the station optical cable safety ground fixation kit.

The purpose of the utility model realizes through following technical scheme:

This OPGW optical cable safety ground fixation kit that enters the station; Comprise surplus cable frame I and surplus cable frame II; Said surplus cable frame I adopts horizontally set; Said surplus cable frame II adopts vertical the setting, and both cross fixation are formed the surplus cable coiling of crosss device, and said surplus cable frame II is provided with at least one and is used for the I of bindiny mechanism that fixes with truss bar;

Said fixation kit also comprises optical cable connecting box; Said optical cable connecting box is provided with and is used for the II of bindiny mechanism that fixes with frame member; Said optical cable connecting box is through ground connection drainage part reliable ground, and the optical cable of being drawn by optical cable connecting box coils through the surplus cable coiling of cross device;

Said fixation kit comprises that also a plurality of being used for be fixed in the stationary fixture on the frame member with optical cable.

Further, said surplus cable frame I and surplus cable frame II include a platy structure, and the two ends of platy structure are arranged to hook-shaped, are used for fixing the optical cable that coils on it;

Further, said I of bindiny mechanism and the II of bindiny mechanism are the anchor ear structure;

Further, said assembly also comprises and draws down steel pipe, saidly draws down that steel pipe is fixedly connected with truss bar through syndeton III, and it is underground to be used for that the surplus cable of cross is coiled the optical cable introducing that device draws;

Further, the inner surface that contacts with truss bar of said surplus cable frame II is provided with insulating barrier.

The beneficial effect of the utility model is:

The structure of the utility model is convenient to OPGW introducing transformer station door type frame ground connection; Can prevent effectively that OPGW from damaging optical cable because of big electric current flows through; Earth point is convenient to break off simultaneously; Do not influence the substation grounding test, meet national relevant technologies standard simultaneously, can therefore not endanger the equipment safety operation of transformer station.

Other advantages, target and the characteristic of the utility model will be set forth in specification subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model and other advantages can realize and obtain through following specification and claims.
