Abstract

An embodiment of the invention discloses a method and a system for detecting foreign matter defects in GIS equipment. The detection method comprises the steps of: adopting training samples of sound signals in the GIS equipment to train a foreign matter defect classification model, wherein each training sample corresponds to a standard type of a foreign matter defect; acquiring sound signals in theGIS equipment at preset time intervals; and inputting the sound signal into the trained foreign matter defect classification model, and outputting the types of the foreign matter defects corresponding to the sound signals, wherein the foreign matter defect classification model is an extended continuous adaptive fuzzy inference system, the extended continuous adaptive fuzzy inference system comprises an input layer, a fuzzification layer, a fuzzy inference layer, a specification layer and an output layer which are sequentially arranged, and nodes of the fuzzy inference layer represent fuzzy rules. According to the method and the system of the invention, the types of foreign matter defects can be obtained, and the method is higher in accuracy rate and efficiency.

Description

technical field [0001] The invention relates to the technical field of GIS equipment, in particular to a method and system for detecting foreign object defects inside GIS equipment. Background technique [0002] Under the grand strategy of the national smart grid, the substation has played an irreplaceable role, because the substation is composed of many confined space equipment, especially GIS (Gas Insulated Switchgear) equipment. If these devices fail, it is necessary to suspend the work of the substation for disassembly and maintenance, which is inconsistent with the goal of improving the reliability of power supply operation of the power grid. [0003] With the rapid development of mobile Internet, sensor technology, and big data technology in recent years, electronic stethoscope technology has also ushered in the spring. Various electronic stethoscopes have been widely used in fault diagnosis, smart medical care and many other aspects. With the rapid development of sci...
