A sensor device for on-line optical detection of air switch position in substation

Abstract

The invention relates to an online light detection sensor device for the position of an air switch in a substation, which includes a light detection device and a light shielding device. The light input channel and the light output channel of the circular hole, the bottom of the light input channel and the light output channel are located on the same horizontal plane, and there is light transmission between the two, the light input channel is provided with a light input optical fiber, and the light output channel is A light output optical fiber is provided, and the bottoms of the light input channel and the light output channel are respectively inclined with a plane mirror, so that the light entering from the light input channel is reflected by the plane mirror and then emitted from the light output channel. The light blocking device is used for Block light transmission between the light input channel and the light output channel. 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 an air switch in a substation. Background technique [0002] The air switch 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, unwrapped and switched on site to operate the electrical primary equipment, the secondary electrical pressure plate and the air switch cooperate with the operation sequence, and human factors are too large. Many, mis-division, mis-combination and incorrect opening-and-closing 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. None of them can detect the status online, and they can no longer meet the high re...

At present, the five-proof lock commonly used in conventional substations in the power grid can only prevent misoperation of electrical primary equipment. None of them can be detected online, and they can no longer meet the high reliability and intelligent requirements of the current and future safe operation of electrical equipment.
