Description

Indoor substation embedded OPGW optical cable terminal box

technical field

The utility model relates to an embedded OPGW optical cable terminal box in an indoor substation, which belongs to the technical field of optical cable communication engineering.

Background technique

OPGW optical cable is a type of optical cable widely used in the field of electric power engineering. It is often used to introduce the termination device of the substation. There are two ways to access it, as shown in Figure 1. One is to fix the joint box and the remaining cable rack in the substation. One is to install the joint box and the remaining cable rack in a floor metal box. According to the operation and maintenance management requirements of the substation, the end of the OPGW optical cable introduced into the substation and the metal part of the termination device must be reliably grounded with the grounding grid of the substation itself. In addition, when measuring the grounding resistance of the substation, the electrical connection between the end of the OPGW optical cable and the metal part of the termination device and the grounding grid of the substation needs to be disconnected.

The two termination devices mentioned above cannot solve the problem of introducing OPGW optical cables into indoor substations. The main reasons are: (1) Indoor substations do not have outgoing wire structures, and the substations occupy a small area and are compactly arranged. The first method is only suitable for Installing the joint box and the remaining cable rack on the wall of the building respectively has great shortcomings in terms of installation convenience, aesthetics and insulation treatment; (2) The floor metal box method takes up a lot of space, which is not suitable for compact indoor substations In this case, there is also the problem that the insulation treatment is also difficult.

Utility model content

Purpose: In order to overcome the deficiencies in the prior art, the utility model provides an embedded OPGW optical cable terminal box in an indoor substation.

Technical solution: In order to solve the above-mentioned technical problems, the technical solution adopted in the utility model is:

An embedded OPGW optical cable terminal box in an indoor substation, including: a box body, and also includes: a vertical beam, a beam, an optical cable joint box, a grounding bus bar, and an optical cable residual cable rack, and vertical beams are respectively arranged on both sides of the box body , a plurality of crossbeams are arranged between two vertical beams, and an optical cable joint box is arranged on the top crossbeam; the grounding bus bar is vertically arranged on the crossbeam; After being vertically connected, they are arranged on the beam; the front panel of the box is provided with an optical cable entry hole, and the bottom panel of the box is provided with an optical cable exit hole.

It also includes a plurality of bottom plate reinforcing ribs, and the multiple bottom plate reinforcing ribs are evenly arranged on the bottom of the box body.

As a preferred solution, the box body is integrally formed with polyester glass fiber reinforced material.

As a preferred solution, there are two exit holes for the optical cable.

Beneficial effects: the indoor substation embedded OPGW optical cable terminal box provided by the utility model has good corrosion resistance, small weight, strong designability, is easy to embed into the wall for installation, and saves the space of the substation; the material has high impact resistance and the device is durable Durable; good insulation performance, easy to connect and disconnect the ground.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 2 and Figure 3, an indoor substation embedded OPGW optical cable terminal box, including: box body 1, vertical beam 2, beam 3, optical cable joint box 4, ground bus bar 5, optical cable remaining cable rack 6, Vertical beams 2 are respectively arranged on both sides of the inside of the box body 1, a plurality of beams 3 are arranged between the two vertical beams 2, and an optical cable splice box 4 is arranged on the top beam 3; the ground bus bar 5 is vertically arranged on On the beam 3; the remaining cable rack 6 of the optical cable comprises two, and the two remaining cable racks 6 of the optical cable are vertically connected to each other and then arranged on the beam 3; the front panel of the box body 1 is provided with an optical cable inlet hole 7, and the box body 1 The bottom panel is provided with an optical cable exit hole 8. It also includes a plurality of bottom plate reinforcing ribs 9 which are evenly arranged on the bottom of the box body 1 .

As shown in Figure 4, the specific implementation method is as follows: the OPGW optical cable is led down through the pipe along the wall and then introduced into the terminal box from the front of the box body. box. The non-metallic optical cable in the substation is welded with the OPGW optical cable in the optical cable splice box, and after being coiled by the remaining cable frame, it is led down by the optical cable outlet hole at the bottom of the box, and the pipe is laid along the wall to the room.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made. Retouching should also be regarded as the scope of protection of the present utility model.
