Embodiment 1

[0017] Embodiment 1, a special network detector for relay protection, its structure is: include working power supply module, optical power / frequency module, network cable test module, splitting module, red light module, display and control panel; Said working power supply module It is a storage battery with an output voltage specification of 9V;

[0018] The working method of the optical power / frequency module is to project the received optical signal on the photosensitive surface of the photodetector and convert it into a current by the photoelectric conversion circuit, and then obtain the voltage signal through the I / V conversion circuit and the amplification circuit. Then send this signal to a low-pass filter for filtering and corresponding degree compensation and amplification, so as to obtain an electrical signal corresponding to the power value, and then convert the voltage through A / D to obtain a digital quantity representing the power, and finally After data processing...

Abstract

The invention discloses a special network detector for relay protection, which belongs to the technical field of relay protection tools and structurally comprises a working power supply module, an optical power / frequency module, a network cable test module, a light splitting module, a red light module, a display and a control panel. The special network detector for relay protection has the advantages that the structure is simple, carrying is convenient, the functions of all network operation inspection tools are integrated, the possibility that all network operation inspection is achieved through a single tool is achieved, and the tool which is powerful in function, rapid and efficient is provided for relay protection network operation inspection work.

Description

technical field [0001] The invention relates to the technical field of relay protection tools, in particular to a special network detector for relay protection. Background technique [0002] With the continuous popularization of smart substations and the continuous improvement of the automation level of substations, the use of optical fiber networks and Ethernet in substations is increasing, and its operation and maintenance have become an important part of relay protection work. Through the statistical classification of the annual abnormal handling work of the relay protection major, it is found that network faults account for 33% of the most frequent faults. However, the currently used network inspection tools have the disadvantages of various types, single functions, and potential safety hazards. Therefore, how to deal with network failures quickly, effectively, and safely is a problem that we must think about at present. Contents of the invention [0003] In view of t...
