Problems solved by technology

If you go through the process, it will take longer
The second reason is that the on-site welding needs to have good weather conditions, and it is generally impossible to operate at night and in rainy and snowy days.
In summary, it is difficult to achieve a real emergency repair
This construction method is increasingly difficult to meet the intelligent development and requirements of the power system
[0005] There are two main problems in the current construction method of repairing broken ADSS optical cables. One is that the repair time is too long, which generally takes 3 days to half a month or more
Second, the maintenance cost is high. Usually, the maintenance cost of a breakpoint, including materials, is between 20,000 yuan and 50,000 yuan.

Embodiment 1

[0037] Such as Figure 1-Figure 7 As shown, the joint assembly 4 is composed of two ADSS optical cable air splicing splice boxes 5 connected by prefabricated optical cables 6, wherein the two ends of the prefabricated optical cables 6 are respectively connected to the stressed bodies 52 of the ADSS optical cable air splicing splice boxes 5. Prefabricated, the connection method can be made non-detachable, so as to give full play to the tensile performance of the connection part. Before installation, a prefabricated optical cable storage box 7 can be provided between the two ADSS optical cable air splicing joint boxes 5. When installing Disassemble it so that it is separated from the ADSS optical cable air splice box 5 at both ends. Wherein the length of the prefabricated optical cable 6 can be 2-5 meters.

[0038]Further, the ADSS optical cable air splice box 5 includes a box body 51, a force receiving body 52 and an optical fiber connector 55, the box body 51 is a hollow shel...

Embodiment 2

[0049] Such as Figure 6 , Figure 7 In this embodiment, the joint assembly 4 is a single ADSS optical cable aerial splice box 5; the structure of the ADSS optical cable aerial splice box 5 is the same as that of the first embodiment, and is also divided into two types, and the specific structure of the stressed body 52 is selected according to the gear distance .

[0050] The joint assembly 4 in the present embodiment is applicable to the situation that there is surplus cable on one side of the fault point, and its splicing method is:

[0051] First, untie the optical cable on the side of the fault point with the remaining cable from the tower 1. The method is to only untie the U-shaped ring on the tower 1, and the pre-twisted wire 58 on the optical cable does not move, which will be used to fix the connection of the optical cable. Part 3 is removed from the hoop 2 on the pole tower 1, and the faulty optical cables are pulled together until the heads of the faulty points of...

Abstract

The ADSS optical cable aerial splicing method of the present invention belongs to the technical field of ADSS optical cable installation, and in particular discloses an ADSS optical cable aerial splicing method; the technical problem to be solved is to provide a novel optical cable aerial splicing method, which can shorten the maintenance and construction time of broken cables, Save a lot of materials and greatly reduce maintenance costs; the technical solution adopted is: ADSS optical cable air connection method, remove the damaged part at both ends of the fault point of the faulty optical cable, and then directly connect the two ends of the optical cable to the stressed body of the joint assembly, the optical fiber and The optical fiber connectors in the joint assembly are connected, and the optical cables on both sides of the fault point are connected in the air by the joint assembly.

Description

technical field [0001] The ADSS optical cable aerial splicing method of the present invention belongs to the technical field of ADSS optical cable installation, and particularly relates to an ADSS optical cable aerial splicing method; it is mainly used to realize the ADSS self-supporting optical cable on the power line when a cable breakage occurs during operation, without increasing or not When the optical cable is replaced, it can be directly connected in the air, and it can be quickly connected at one time, and it can be used in special cases such as power line rerouting. Background technique [0002] With the development of the power grid, more and more ADSS optical cables are hung on the power line, especially the aerial optical cables of the rural power grid are almost all self-supporting ADSS optical cables. Because its environment is often more complex urban environment. In actual operation, due to complex reasons such as cities, factories and mines, road constructi...
