Abstract
The utility model relates to a waterproof optical cable down lead welding box. The structure is that the bottom part of a box body is provided with an optical cable up lead tube, the upper part of the box body is provided with a connector box bracket, and a connector box is arranged on the bracket. The waterproof optical cable down lead welding box leads an OPGW (optical fiber composite overhead ground wire) into the box body directly from a door frame steel tube tower, and an ADSS (all-dielectric self-supporting) optical cable up lead tube, which is in butt joint with the OPGM and leads to a machine room, also goes into the box, and then the ADSS optical cable penetrates through the ADSS optical cable up lead tube, thereby being good in optical cable down lead waterproof effect; a core breaking phenomenon caused by weak sealing of the ADSS optical cable down lead of the optical cable does not occur; the installation is simple and the construction is convenient; and the optical cable is convenient in connection, thereby being not only waterproof but also beautiful.
Description
Technical field
The utility model relates to a kind of optical ca ble protection device, relates in particular to a kind of water proof type optical cable and draws welding case down, mainly is applicable to OPGW optical cable introducing substation project, belongs to the power communication application.
Background technology
Along with electric system is more and more higher to the requirement of safety and stability and robotization; form the SDH looped network with OPGW for the backbone transport media and will obtain promoting and development for digital data transmission such as executive scheduler, remote automation, relay protection channel, power grid security automatic control system provide the main thoroughfare, OPGW has obtained using widely.
But the OPGW optical cable really exists not enough in installation process, and it draws the lower part, and namely there is a difficult problem in terminal part.The OPGW optical cable not only will use but also will be as the transmission channel of communication as ground wire as composite overhead ground wire, and this just need be connected by cable from communications equipment room to electric substation's door type framework, just Chang Yong ADSS optical cable.ADSS is All Dielectric self-support, and it is nonmetallic entirely, has the self-supporting ability again.Adopted the high strength aramid yarn with high elastic modulus as the anti-element of opening in the manufacturing.Outer nonmetallic materials black high density polyethylene oversheaths (HDPE) and the black high density anti-electric-mark oversheath (AT) of adopting of optical cable.The ADSS optical cable draws down by passing in the cable duct that pipe is come a type framework and OPGW docks, and problem is often drawn down in the pipeline with regard to appearing at this optical cable of several meters.Because the ADSS temperature influence, shutoff is not tight down owing to draw, and do not remain in ponding pipe in case water inlet row goes out rainy season, replaces in season in the Winter-Spring, and along with weather one cold one is changed, the ADSS optical cable is easy to be expanded disconnected.Especially in the north, the big area of the changes in temperature temperature difference in winter in spring, this problem is just particularly serious.
Summary of the invention
The utility model provides a kind of water proof type optical cable to draw welding case down at above-mentioned problems of the prior art, has solved the problem that optical cable is subjected to weather effect to be expanded easily and break in the prior art.
The technical solution of the utility model is as follows:
The bottom of casing arranges optical cable and draws pipe, and the top of casing is provided with the connector box carriage, and connector box is placed on the carriage.
The top of described casing is provided with rain and takes.
Be provided with the surplus cable frame of optical cable in the described casing.
The structure of the surplus cable frame of described optical cable is, support body is arranged to cruciform shape, and U-shaped is arranged in the outer end revolution of support body, and baffle plate vertically is set on the U-shaped outer.
Described baffle plate is provided with the optical cable wire casing.
The utility model has the advantages of as follows:
1, the OPGW optical cable is directly introduced casing the inside from door structure steel tube tower, and butt joint goes the ADSS optical cable of machine room to draw pipe also to enter in the case with it, and then penetrate the ADSS optical cable, optical cable draws time good water-proof effect; Can not draw down shutoff because of the ADSS optical cable and sternly not cause the optical cable core phenomenon of breaking; Install simply, it is convenient to construct; Cable connection is convenient, not only waterproof but also attractive in appearance.
2, take by rain is set, better guaranteed waterproof effect.
3, the surplus cable frame of optical cable integral body is arranged to cruciform shape, has namely saved the space, convenient remaining cable setting again, and U-shaped and vertical baffle are arranged in the end, are easy to the convenient winding of fixed cable, and by wire casing, make things convenient for cable to fix, control trend easily.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, rain takes, 2, connector box, 3, casing, 4, draw pipe, 5, remaining optical cable, 6, the surplus cable frame of optical cable, 7, carriage, 8, baffle plate.
Embodiment
Following with reference to accompanying drawing, in conjunction with specific embodiments, describe the utility model in detail.
Embodiment
As shown in Figure 1, the top of casing 3 is provided with rain and takes 1, and the bottom of casing 3 arranges optical cable and draws pipe 4, optical cable passes and draws pipe and enter box house butt joint, the top of casing 3 is provided with connector box carriage 7, and connector box 2 is placed on the carriage 7, is provided with the surplus cable frame 6 of optical cable in the casing, remaining optical cable is wrapped on the support body, the structure of the surplus cable frame of optical cable is, support body is arranged to cruciform shape, and U-shaped is arranged in the outer end revolution of support body, baffle plate 8 vertically is set on the U-shaped outer, and baffle plate is provided with the optical cable wire casing.
The utility model becomes at 500 kilovolts of A, 220 kilovolts of B become in the construction project, and 220 kilovolts of C become, D become in the improvement project and test, and its optical cable draws good water-proof effect down; Can not draw down shutoff because of the ADSS optical cable and sternly not cause the optical cable core phenomenon of breaking; Install simply, it is convenient to construct; Cable connection is convenient.
