Description

Special substation optical cable connector for power system

technical field

The invention relates to a power system special substation optical cable connector.

technical background

At present, the connection method of optical cables in smart substations is: "on-site fusion splicing + ODF optical fiber distribution frame + optical fiber jumper" connection method. The fusion splicing process is complicated, and the workers for splicing optical fibers need to be recruited separately, increasing the management process. The operation level of personnel is uneven; optical fiber fusion is affected by environmental temperature, humidity and dust; fusion is time-consuming and laborious, and the construction period and debugging period of fusion splicing are long, which affects the progress of the project; optical fiber fusion splicing Points require special protection to prevent breakage. If the traditional plug-in is used, the firmness is low, and the protection of the traditional plug-in device is poor, and it is easy to connect the optical fiber to the cable. The traditional optical fiber plug-in accepts a large impact on the environment and cannot meet the requirements of the optical fiber connection of the smart substation.
