Abstract

The invention relates to the technical field of an optical cable verification device, in particular relates to a device for verifying localized protection prefabricated optical cable, and in particular to a realization method for the verifying the localized protection prefabricated optical cable in the technology field of smart grid. The method comprises a transmitting end light source device anda receiving end optical power meter device; the transmitting end light source device comprises a local source test port and a prefabricated optical cable test port, wherein the local source test portis connected to the first receiving end optical power meter device, and the prefabricated optical cable test port is connected to the prefabricated optical cable interface tested; an optical cable dispersion port tested is connected to the second receiving end optical power meter device; and the first receiving end optical power meter device and the second receiving end optical power meter deviceare connected through a wireless autonomous network. The device has the advantages of simple structure, small light loss error, and comprehensive and scientific test results. Therefore, it is beneficial to comprehensively analyze the requirements of optical cable performance and special optical cable mode, save test time and avoid the influence of differential damage, and can be used for multi-fiber bundle testing to solve the problem that it is difficult to verify the localized protection prefabricated optical cable.

Description

technical field [0001] The present invention relates to the technical field of an optical cable calibration device, in particular to an in-situ protection prefabricated optical cable calibration device, in particular to a method for implementing in-situ protection prefabricated optical cable calibration applied in the technical field of smart grids. Background technique [0002] The in-situ relay protection device is a new form of relay protection for the third generation of smart substations of the State Grid Corporation of China, and it is also a new direction for the development of relay protection devices in the future. Prefabricated optical cables are an important supporting link for on-site protection, and the inspection of prefabricated optical cables will also become one of the important contents of the on-site inspection of "in-situ relay protection devices", and it is also the key to improving the efficiency of on-site operation and maintenance of relay protection. ...
