Transformer station guiding optical cable optimization laying system

Abstract

The invention provides a transformer station guiding optical cable optimization laying system which comprises a communication machine room and a relay house. Two multi-core guide optical cables connect the communication machine room with the relay rouse. The guide optical cables are installed in conduits through two cable grooves or pipes with different paths, and get in and out the communication machine room and the relay house through two different cable holes. The communication machine room and the relay house connect with a specially configured power distribution unit through the guide optical cables, and get OPGW (Optical Fiber Ground Wire Cable) external connection through the power distribution unit. The power distribution unit is an intersection unit of cable configuration. A power distribution area is provided with a set of optical cable intersection box which is arranged at an outlet interval middle position and near the cable grooves, and the optical cable intersection box is used for cable distribution and splice between cables from an optical cable splice box direction and cables from communication machine room and relay house directions, wherein the cable splice employs a welding mode. The transformer station guiding optical cable optimization laying system has the characteristics of improvement of overall reliability of an optical cable line, simplification of operation work, and reduction of optical cable laying workload to achieve a scientific, reasonable and reliable effect and the like.

Description

technical field [0001] The invention relates to a new type of guiding optical cable laying system in a substation, which belongs to the optical cable network system of a power communication network, and mainly provides a more efficient and reliable technical solution for laying and connecting guiding optical cables in a substation. technical background [0002] With the development of communication technology, optical fiber communication has become the main communication mode of power communication network, and OPGW optical cable has become the main type of optical cable of power communication network. At the same time, combined with the need for line protection fiber optics, the construction of OPGW optical cables has grown rapidly. At present, the laying of guiding optical cables in substations mainly adopts the delta connection method, such as figure 1 As shown, that is, the frame optical cable connection box-communication room-relay room-framework cable connection box, ...

AI Technical Summary

Problems solved by technology

[0004] 1. The communication room cannot uniformly plan the wiring, which increases the workload of operation and maintenance, which is not conducive to rapid troubleshooting

[0005] 2. A large number of guiding optical cables are laid in stages, and it is necessary to repeat the work of uncovering the cable cover and sealing the fire of the cable trench, and the workload of laying optical cables is heavy

[0006] 3. In the later stage of guiding optical cable laying project, it is easy to have shallow embedded depth of optical cable and substandard safety protection measures, which reduces the reliability of optical cable line

[0007] 4. There are too many optical cables laid in the cable trench, which requires high safety measures such as fire prevention
