Problems solved by technology
[0003] In order to solve the above problems, the present invention provides a new type of segmented insulated intelligent optical cable splice closure, which can take into account the optical fiber connection of OPGW optical cable and the release circuit function of the impact of short circuit or lightning strike on the optical fiber, and solves the problem of optical cable splicing in the prior art. The box is bulky and requires an additional installation platform. While performing segmental insulation, it can also realize the sensing function of optical fiber status, so as to realize the light weight, miniaturization and intelligence of the splice box

Abstract
The invention provides a segmented insulating intelligent optical cable connector box. The segmented insulating intelligent optical cable connector box comprises a cylinder body; wire passing holes are formed in two ends of the cylinder body; an inner layer preformed armor rod and an optical fiber of an OPGW optical cable pass through the wire passing holes; the outer side wall of the cylinder body is used for supporting the inner side of an outer layer preformed armor rod of the OPGW optical cable; and the optical fiber extends into the cylinder body to be subject to connection; an optical fiber sensor is arranged on the inner side of the cylinder body and connected to at least one core wire of the optical fiber. The segmented insulation intelligent optical cable connector box has the maintenance-free and good connection functions; the design of an existing optical cable circuit is not affected, the light weight, miniaturization and intelligence of the connector box are achieved, an operation state sensing unit is additionally arranged while segmented insulation is conducted, then a line state is sensed; real-time intelligent monitoring of the state in the box is carried out through the optical fiber sensor, safe operation and state perception of a line are guaranteed, and construction of an intelligent power grid and an electric power internet of things is powerfully supported.
Description
technical field [0001] The invention relates to the technical field of optical fiber composite overhead ground wire (OPGW) such as power transmission and distribution, in particular to a segmented insulated intelligent optical cable joint box. Background technique [0002] As an important node equipment for transmission line business dispatching, monitoring, relay protection and other optical signal communication transmission, the optical cable junction box has extremely important product quality, operation and maintenance. The quality problem of the optical cable splicing box is likely to cause the interruption of the optical cable, increase the repair time and seriously affect the operation safety of the transmission line. At present, the vast majority of OPGW optical cables in my country adopt the installation method of tower-by-tower grounding, and the line loss is serious. The best way to solve this problem is to adopt the segmented insulation installation method, such ...
