Abstract

The invention relates to a power transmission line straight tower OPGW connection point deployment structure and method.The power transmission line straight tower OPGW connection point deployment structure comprises an OPGW connection box and a triangular connection plate, the triangular connection plate is in an isosceles triangle shape, the top corner portion of the triangular connection plate is hung on a cross arm of a straight tower, and OPGW optical cables on the two sides are hung on the two bottom corner portions of the triangular connection plate; the OPGW optical cables on the two sides are led down to the lower portion of the straight line tower and are connected through the OPGW connecting box, and the OPGW connection box is connected with emerging service communication equipment installed on the straight line tower through a branching optical cable. According to the invention, the technical breakthrough of deploying the OPGW connection points and installing the OPGW connection box on the straight line pole tower is realized, the requirement of accessing the OPGW optical fibers by emerging services is met, the flexible use of section OPGW communication can be met according to the special requirements of the emerging services, the utilization rate of the large-core-number OPGW is greatly improved, the practicability is high, and huge economic and social benefits are generated.

Description

technical field [0001] The invention relates to a structure and a method for deploying OPGW connection points of straight poles and towers of transmission lines. Background technique [0002] The tower types of high-voltage transmission lines are mainly divided into two types: straight towers and tension towers. In terms of force design, the linear pole tower can only bear the vertical load and the horizontal load caused by the wind, and cannot bear large lateral unbalanced tension. The linear pole towers account for the majority of the entire route. According to the existing engineering design standards, it is generally impossible to choose a straight pole tower as the OPGW connection point for deployment and installation of an optical fiber connection box, and the OPGW optical fiber cannot be connected to emerging services. [0003] In terms of force design, the tension tower can not only bear vertical load and horizontal load caused by wind force, but also can bear large...

Problems solved by technology

After the transmission line is put into operation, the power outage changes the operation mode of the power system, which affects the lives of residents, industrial production and power grid safety. The power outage technology is difficult, the economic cost is high, and the social impact is large; at the same time, the operation mode of the OPGW optical fiber is changed to affect the scope of the communication network and the construction work time. Long, little chance of approval to cut fiber for retrofit

[0007] In addition, due to the vigorous development of emerging businesses such as smart transmission line status monitoring system devices, intelligent sensing terminals, and 5G communication network base stations, according to the requirements of their respective business characteristics, the hanging equipment is installed on the transmission line towers according to actual needs (tension-resistant iron towers or straight-line tower), but the existing straight-line tower does not arrange OPGW connection points, it is impossible to extract optical fiber access communication equipment to form an optical communication transmission network, and it is impossible to achieve the expected goal of optical fiber transmission

[0008] Retrofitting linear towers of high-voltage transmission lines into strain-resistant towers requires a large investment (the construction cost of each base tower is hundreds of thousands to millions of yuan), long construction time, great impact of power outages, high difficulty in implementation, and low economic and social benefits
