Description

technical field

[0001] The invention relates to the technical field of acoustic wave positioning equipment, in particular to a portable substation noise imaging positioning detection device. Background technique

[0002] With the refinement of management, humanization of service, and standardization of data in electric power enterprises, the requirements for periodic testing and random testing of the operating status of electrical equipment are getting higher and higher, and the traditional listening and identification has been difficult to solve completely. On-site technical issues; research has found that any electrical equipment in operation, due to the action of alternating current, will produce various sounds and vibrations, these sounds and vibrations are unique to operating equipment, and are a feature that indicates the operating status of the equipment . For example, substations are mostly in an environment with multiple noises, most of which are power frequency so...
