Electric power communication optical cable wiring method and ring network system

Abstract

The invention discloses an electric power communication optical cable wiring method and a ring network system. The method comprises the following steps of 1, arranging an optical cable splice closure, leading an electric power communication optical cable into the optical cable splice closure from a transformer substation, and forming an incoming optical cable; 2, selecting empty screen cabinets with ODF optical fiber distribution frames on two sides in a secondary equipment room, setting one empty screen cabinet as a communication light distribution screen, and setting the other empty screen cabinet as a protection light distribution screen; 3, laying an optical cable from the communication light distribution screen and connecting the optical cable to the optical cable splice closure to form a first guide optical cable, and laying an optical cable from the protection light distribution screen and connecting the optical cable to the optical cable splice closure to form a second guide optical cable; and 4, a third guide optical cable used for connecting the two cabinets being laid between the communication light distribution screen and the protection light distribution screen. The ring network system comprises an optical cable splice closure, a communication light distribution screen and a protection light distribution screen which are connected with one another through guide optical cables to form an annular loop. According to the method, the risk of transmission channel shutdown caused by fiber breakage of the optical cable is eliminated.

Description

technical field [0001] The invention relates to the technical field of power communication, in particular to a power communication optical cable wiring method and a ring network system. Background technique [0002] The power communication network is like the nervous system of a power company, directly responsible for the transmission and feedback of important information such as power grid dispatching control, equipment inspection, infrastructure construction, marketing, customer service, and administrative management. link. Due to the advantages of light unit weight, large transmission capacity, small process attenuation, strong anti-interference ability, and good confidentiality, optical fiber communication has replaced cable communication, high-voltage power line carrier communication and microwave relay communication, etc., and has become the main communication network of modern power grids. form. [0003] Outside the substation, the power communication optical cable ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a power communication optical cable wiring method and a ring network system, aiming to solve the problem that the existing power communication optical cable routing scheme is single, and once the only optical cable route is damaged, the entire substation will be disconnected from the network and lost connection.
