Testing equipment and testing method for wind-induced vibration and galloping performance of optical cable

Abstract

The invention relates to testing equipment for wind-induced vibration and galloping performance of an optical cable, and the equipment comprises terminal supports which are disposed at two ends of the test equipment; an optical fiber connector which is used for fixing one end of a to-be-tested optical cable; a force measuring mechanism which is used for measuring the tensile force of the end part of the to-be-measured optical cable; an optical fiber dispersion test system which is used for being connected to the end part of the to-be-tested optical cable so as to measure the change conditions of the optical fiber length and attenuation under the typical wavelength of the optical transmission window; a suspension device which is used for supporting the middle position of the to-be-tested optical cable; a middle support which is used for supporting the two ends of the to-be-tested optical cable; a vibration exciter which is used for exciting the to-be-measured optical cable on a vertical plane; and a terminal device which is used for clamping the optical cable. An electronic vibration exciter is adopted to excite the optical cable on a vertical plane, and the fatigue performance of the optical cable and the optical performance change of optical fibers in the optical cable are simulated and determined under the vibration condition that the actual operation stress state of the optical cable is different.

Description

technical field [0001] The application belongs to the technical field of optical cable testing, and in particular relates to a test device and test method for wind-induced vibration and galloping performance of optical cable. Background technique [0002] ADSS optical cable, All-dielectric Self-supporting Optical Cable (also known as all-dielectric self-supporting optical cable). All-dielectric means that the optical cable uses all-dielectric materials. Self-supporting means that the strengthening member of the optical cable itself can bear its own weight and external load. [0003] OPGW optical cable, Optical Fiber Composite Overhead Ground Wire (also known as optical fiber composite overhead ground wire). The optical fiber is placed in the ground wire of the overhead high-voltage transmission line to form an optical fiber communication network on the transmission line. This structure has dual functions of ground wire and communication, and is generally called OPGW optical...
