Power transmission and distribution line fault visualization detection system and method

Abstract

The invention discloses a power transmission and distribution line fault visualization detection system. The system comprises a UHF sensor used for detecting partial discharge, an ultraviolet imager and an operation terminal. The UHF sensor also comprises a signal processing unit and a detection host. The ultraviolet imager comprises an ultraviolet imaging module and a display transmission module;the ultraviolet imaging module is composed of a spectroscope, a UV imaging lens, an imaging objective lens, a CCD camera, a UV image intensifier and an acquisition processing superposition display module. The method has the beneficial effects that compared with the traditional detection method, the method can visually display the discharge position and the discharge form of the operation equipment, and has the characteristics of strong anti-interference capability, accurate discharge point positioning and high sensitivity.

Description

technical field [0001] The invention relates to the technical field of circuit fault detection, in particular to a visual fault detection system and method for power transmission and distribution lines. Background technique [0002] The development of smart grid is a world trend. It focuses on improving energy utilization efficiency and power quality, and ultimately achieves higher social and economic benefits, and achieves the goals of energy saving, emission reduction, and environmental protection. [0003] my country has a vast territory, and the natural distribution of energy is dispersed. Coal resources are mainly stored in the northeast, north, northwest, and border areas. Hydropower is mainly distributed in the west and southwest. The focus of energy consumption is mainly in the economically developed areas along the eastern coast. It is necessary to build a safe and reliable energy transmission channel, so the State Grid defines smart grid as a grid with UHV grid as ...

Problems solved by technology

[0005] The traditional manual line inspection method not only has a large workload but also has difficult conditions, especially for inspections of mountainous areas and transmission lines across large rivers, as well as line inspections during ice disasters, floods, earthquakes, landslides, and nights. It takes a long time, The cost of manpower is high and the difficulty is great. It is still difficult to complete the manual inspection method of some line areas and some inspection items. Therefore, some recorded inspection equipment has appeared in the prior art. However, in the existing airborne inspection equipment, there is no Found that it has high integration and miniaturization can complete the high-frequency method and solar-blind ultraviolet imaging detection system
