An online optical detection and sensing device for the position of the electrical secondary pressure plate in a substation

Abstract

The invention relates to an on-line optical detection and sensing device for the position of an electric secondary pressure plate in a substation, which includes a protective cover and a positioning plate installed in the protective cover. The light column and the exit positioning light guide column, the input positioning light guide column and the exit positioning light guide column are respectively embedded with optical fibers of the same size, and the edge of the protective cover is provided with an optical input optical fiber, an input optical output optical fiber and an exit optical output optical fiber, The two ends of the input positioning light guide column can be connected to the ends of the light input optical fiber and the input light output optical fiber respectively by rotating the positioning disc, and the two ends of the withdrawal positioning light guide column can be respectively connected to the ends of the optical input optical fiber by rotating the positioning disc. The light input fiber and the end of the light output fiber are connected. The invention improves the safety and reliability of the operation of the substation and the level of intelligent detection, effectively prevents the switching and misoperation of the inspection personnel, and reduces the operation and maintenance cost of the inspection.

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
