Online optical detection sensing device for electric secondary pressure plate position of substation

Abstract

The invention relates to an online optical detection sensing device for an electric secondary pressure plate position of a substation. The online optical detection sensing device comprises a protective cover and a locating plate, wherein the locating plate is arranged in the protective cover; a rotating shaft is arranged at the center of the locating plate; an input locating light guide post and an exit locating light guide post are arranged in the rotating shaft; optical fibers with the same sizes are respectively embedded into the input locating light guide post and the exit locating light guide post; a light input optical fiber, an input light output fiber and an exit light optical fiber are arranged on the edge of the protective cover; two ends of the input locating light guide post are respectively connected with the end parts of the light input optical fiber and the input light output optical fiber through rotating the locating plate; and two ends of the exit locating light guide post are respectively connected with the end parts of the light input optical fiber and the exit light output optical fiber through rotating the locating plate. According to the online optical detection sensing device, the operation safety and reliably and the intelligent detection level of the substation are improved; a switching misoperation of an inspector is effectively prevented; and the inspection, operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of light detection and sensing, in particular to an on-line light detection and sensing device for the position of a substation electrical secondary pressure plate. Background technique [0002] The electrical secondary pressure plate is the most common component in the substation. It is distributed and assembled on various electrical equipment. When the electrical secondary pressure plate is cast, unsealed and on-site switching is used to operate the electrical primary equipment, the electrical secondary pressure plate must cooperate with the electrical primary equipment operation sequence. There are too many human factors, wrong input, wrong solution, incorrect input and solution, and incorrect input and solution sequence cannot be prevented by technical means. At present, the five-proof lock commonly used in conventional substations in the power grid can only prevent misoperation of electrical primary equi...

[0002] The electrical secondary pressure plate is the most common component in the substation. It is distributed and assembled on various electrical equipment. When the electrical secondary pressure plate is cast, unsealed and on-site switching is used to operate the electrical primary equipment, the electrical secondary pressure plate must cooperate with the electrical primary equipment operation sequence. There are too many human factors, wrong input, wrong solution, incorrect input and solution, and incorrect input and solution sequence cannot be prevented by technical means. At present, the five-proof lock commonly used in conventional substations in the power grid can only prevent misoperation of electrical primary equipment. The status and position of the secondary pressure plate of the electrical outlet in the smart substation also cannot be detected online, which can no longer meet the current and future high reliability and intelligent requirements for the safe operation of electrical equipment
