Problems solved by technology

[0003] Among them, the conductive rod should be located in the center of the shell, but in actual use, the conductive rod will have a tilt fault
Due to the closed nature of GIS equipment, it can only be detected by X-ray imaging. For some small tilts, the naked eye cannot effectively distinguish them in the picture; resulting in low efficiency and low accuracy of film evaluation by staff

Embodiment

[0017] The GIS equipment fault detection method based on the geometric method in this embodiment is suitable for figure 1 The GIS equipment shown, the GIS equipment includes: shell A, contact B, pot insulator C, conductive rod D and pillar insulator E; wherein, the position of the conductive rod in the GIS is to connect the pot insulator and the pillar insulator, and the shell A It is a cylindrical shape, and the conductive rod D is in the center of the shell A. Therefore, the problem of the tilt failure of the conductive rod can be transformed into a geometric problem. When the conducting rod D is inclined, the distance d from the contour edge of the conducting rod D to the casing A is a variable amount, which may increase or decrease. If d does not change, it means that the conducting rod is in a normal state. Therefore, for the intrusion and tilt fault of the conductive rod, the selected characteristic parameters are the rate of change of the slope k and the distance d; it ...

Abstract

The invention relates to a GIS equipment fault detection method based on a geometric method. The GIS equipment fault detection method comprises the steps of image acquisition, statistical distance judgment, calculation slope judgment and the like. According to the GIS equipment fault detection method based on the geometric method, the fault problem is converted into the mathematical geometric problem, the selected characteristic parameters are the variable quantities of the slope k and the distance d, whether the conducting rod has the inclination fault or not is judged according to the two characteristic parameters, and the reliability and accuracy of detection are guaranteed. A mathematical geometric method is adopted for detection, the inclination fault of the conducting rod in the GIS is detected and recognized, and the purposes of reducing the film reading workload of professionals and predicting potential faults in advance can be achieved.

Description

technical field [0001] The invention relates to an image detection method for GIS equipment failure, belonging to the technical field of power grid maintenance. Background technique [0002] Gas insulated switchgear (GIS for short) is a new type of electrical device that appeared in the 1960s. It is an important protection and control device for power systems. , conductive rods and pillar insulators. [0003] The conductive rod should be located in the center of the housing, but in actual use, the conductive rod will have a tilt failure. Due to the closed nature of GIS equipment, it can only be detected by X-ray imaging. For some slight tilts, the naked eye cannot effectively distinguish them in the pictures, resulting in low efficiency and low evaluation accuracy of the staff. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is: to overcome the shortcomings of the above-mentioned technologies, and to provide a method for dete...
