Power system intelligent station fiber interface conversion apparatus

Abstract

Disclosed is a power system intelligent station fiber interface conversion apparatus. The apparatus comprises a fiber switch and a fiber converter. One end of the fiber switch is respectively connected with an ST female joint and an LC female joint, the other end of the fiber switch is respectively connected with the fiber converter, an ST son joint, an LC son joint, an SC son joint and an FC son joint, and the fiber converter is connected with a netting twine joint. According to the invention, the problem of inconvenience caused by existence of multiple interfaces to maintenance work when such devices as an intelligent transformer station and the like are connected with a test instrument is solved effectively; the fiber switch is employed for connection, the loss is small, the data packet capture requirement is met, and the fiber converter can conveniently realize photoelectric conversion; data exchange between the two female joints and the four son joints is supported; and the apparatus can be directly connected with a notebook computer, can also cooperate with a hand-held digital analyzer, performs packet capturing and data acquisition on fiber interfaces of multiple types, is convenient and fast to operate and high in practicality, and greatly improves the work efficiency.

Description

technical field [0001] The invention relates to an optical fiber interface conversion device of an electric power system intelligent station, belonging to the technical field of detection and analysis of electric power system intelligent stations. Background technique [0002] The construction of my country's smart grid has risen to the level of national strategy. A notable feature of smart substations is the networking of secondary equipment, which changes the way of information transmission and replaces cable connections with optical fibers and network communications. Therefore, in operation and maintenance, when a substation fails, it is necessary to use hand-held digital signal analyzers, optical power meters, digital protection testers and other instruments to capture and analyze optical fiber data, check the transmission power of optical fiber interfaces, and protect The equipment is debugged and verified. [0003] However, at present, there are many manufacturers of...

AI Technical Summary

Problems solved by technology

[0003] However, at present, there are many manufacturers of protective devices in substations, and there are different types of optical fiber interfaces, and the current test instruments only support one type of optical fiber interface, and the price of one tester can easily cost more than 100,000 yuan. A conversion device that supports all types of optical fiber interfaces, and can cooperate with various testing instruments to find and eliminate faults

[0004] At present, the common practice of optical fiber interface conversion devices on the market is to use physical connection, through simple optical fiber mechanical fusion, the more optical fiber heads are converted, the greater the loss
