GIS apparatus with discharge observation window

Abstract

The invention relates to a GIS apparatus with a discharge observation window and belongs to the technical field of online high-voltage switch monitoring. According to the GIS apparatus, the observation window is designed on the side surface or the top surface of a GIS cavity, and the diameter of the observation window and the angle of inclination of the axis of the window to ground can be determined according to the generatrix length and the angle of inclination of the section of a basin-type insulator cone in the GIS cavity. As the observation window is arranged on the GIS cavity, the position of partial discharge, the arc shape, the defect type and the like can be visually seen, and the problem of failure in visually knowing the optical phenomena in the development process of the GIS partial discharge process is solved; meanwhile, in combination with other partial discharge diagnosis methods, the partial discharge information is diagnosed comprehensively; the methods are complementary to each other for verification to make up for misjudgment possibly caused by one single method.

AI Technical Summary

Benefits of technology

This patented technology allows researchers to visually inspect electrical equipment without actually touching any part they are doing their work. It uses a special device called a ghost box placed inside the chamber where there's no electric current flow through them. By setting this angle between the bottom of the tank body and its upper edge, which helps explain how different parts have been affected during partial discharges like arcs and voids. These devices also help identify fault types such as short circuits and open circuit failures. Overall, these technical feature enhances understanding of partial charge phenomena while reducing errors associated with traditional techniques used to detect partial charges.

Problems solved by technology

The technical problem addressed in this patented method relates to understanding how dark phenomenon occurs during partial discharges when there's an electric arc between two electrodes within a device called a gasket or seal (GIS).
