Problems solved by technology

The extensive use of optical fibers has led to a problem. Before the secondary test or during other defect elimination tests, the optical fiber head needs to be removed. At this time, the optical fiber plug loses protection, which may scratch the optical fiber head, resulting in data transmission failure. Fault

Abstract

The invention relates to a tail fiber safety measure dustproof protective cap applied to intelligent substation protection equipment. The protection cap comprises a locking device and a protective cap, wherein the locking device and the protective cap are in threaded connection, the locking device comprises a lower fixing plate and an upper fixing plate, the lower fixing plate is provided with lower grooves arranged in parallel, one ends of the lower grooves are provided with two clamping blocks, the clamping blocks are fixed on the lower fixing plate and respectively located on both sides ofthe lower grooves, one of the two clamping blocks is provided with a fastening bolt hole, the fastening bolt hole is provided with a fastening bolt, the other ends of the lower grooves protrude from the outer edge of the lower fixing plate to form a lower convex groove, and the lower convex groove is externally provided with an external thread. The protective cap saves manpower, is convenient to operate, and simple in structure, and can not only prevent the optical fiber from being scratched, and facilitate the external connection of the optical fiber by opening the protective cap to improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of protective devices, in particular to a pigtail safety measure dustproof protective cap applied to intelligent substation protection equipment. Background technique [0002] The advantages of optical fiber communication are: (1) Large communication capacity and long transmission distance; the potential bandwidth of an optical fiber can reach 20THz. With such a bandwidth, it only takes about one second to transmit all human written materials from all over the world. At present, the 400Gbit / s system has been put into commercial use, and the loss of the optical fiber is extremely low. When the optical wavelength is around 1.55μm, the loss of the quartz optical fiber can be lower than 0.2dB / km, which is lower than the loss of any transmission medium at present. No relay The transmission distance can reach dozens or even hundreds of kilometers; (2) the signal crosstalk is small and the confidentiality performan...
