The safe operation of electrical equipment is very important to the stability of power system. In recent years

the bionic olfactory sensing technology is a hot research topic both at home and abroad and has been used successfully in the field of food inspection

quarantine

search and rescue. The technology can also be used to detect defects or faults of electrical equipment. The defects or faults of electrical equipment can be identified further by way of detecting metal conductors and specific odor molecules emitted by the gas

liquid or solid insulation of the electrical equipment

and can be combined with visual and auditory for diagnostic analysis. In this paper

the development process of the bionic olfactory sensing technology is described firstly

the principle

technical characteristics and research progress of three generations of bionic olfactory sensing technology are expounded

and its application scenarios and development direction are discussed. Then

the gas detection technology of present electric power equipment is summarized and analyzed from the perspective of fault identification of gas

liquid and solid insulation media

and the applicable scenarios and advantages of bionic olfactory sensing technology are proposed. Finally

the future application prospects and key issues of the bionic olfactory sensing technology are analyzed in combination with the development and research direction of bionic olfactory sensing technology

and the research prospects of bionic olfactory sensing technology in the future are proposed.
