Description

Adjustable corner fiber optic reel box

technical field

The invention relates to wiring equipment for optical fiber communication, in particular to an optical fiber reel box installed at the turning point of optical fiber and used for laying optical fiber in the secondary equipment screen of an intelligent substation.

Background technique

With the development of smart grid, the number of smart substations is increasing year by year. In the intelligent station, optical fiber is mainly used for communication and data transmission to replace the traditional power control cable. According to the relevant requirements of optical fiber laying in the intelligent station: the optical fiber pigtail should present a natural bend (bending radius greater than 30mm, arc greater than 90°), and there should be no bends. The phenomenon of folding and nesting should not bear any external weight. However, the physical characteristics of the optical fiber itself make it less flexible. Excessive bending will lead to increased attenuation of the optical fiber and even interruption of data transmission. At present, during the construction of the intelligent station, the optical fiber in the screen is still laid according to the traditional secondary cable box. The corner of the box is at a right angle. When the optical fiber is bent, it is easy to cause excessive bending and exceed the specified requirements.

At present, the optical fiber pigtails in the smart station panel are basically not properly handled. During construction, the optical fiber is still laid according to the traditional cable trunking box, resulting in excessive bending of the optical fiber at the corner, large optical attenuation, and interruption of optical fiber signal transmission. possible.

Further, the guide rail card is a Phoenix terminal card, and is fixed on the guide rail; the radian scale is fan-shaped, with a maximum angle of 45°, and 7 round holes are set on the scale. After the angle is adjusted, the angle adjustment rod is adjusted by the angle adjustment bolt. fixed on the arc scale.

Further, the multi-layer disc spool has a three-layer structure, which is fixedly connected by three discs and three circular shafts, and is set on the base, wherein the base, the discs and the circular shafts are the same center of circle, and the base The radius is greater than the radius of the disc, which is greater than the radius of the shaft, which has a radius of 35mm.

Further, the outer diameter of the dust-proof cover is the same as that of the base, and three pairs of optical fiber inlets and outlets are opened on the dust-proof cover to match with the three-layer bobbins.

The beneficial effect of the present invention is that, through the optical fiber corner coil box with adjustable base angle, it is possible to realize the intact laying and storage of optical fibers and spare wire cores in the screen of the intelligent station, ensure the safe operation of the intelligent equipment, and maintain the stability of the intelligent grid.
