The X ray projective technique is used in combination with acoustoelectric combined method in the application that the power equipment insulation detects, both can realize the detection of insulation of electrical installation defective, can take pictures to electrical equipment by the X ray projective technique again, realize visual location insulation defect.
Because electrical equipment is arranged intrinsic characteristics in the electric system, as outdoor spacious, highly high slightly, especially the GIS kind equipment is arranged compactness to indoor equipment, the space is narrow and small but there highly have height to have to be low, and as the up-to-date application technology of a kind of electrical equipment, what its actual application need was a large amount of groping and studying.Through-transmission technique owing to the reason of electrical equipment size often imaging be a part, add the difference of arranging the orientation, its inner components can produce distortion, be familiar with the prerequisite that this technology can effectively be used for in-built, and space multistory sense and irradiation multi-faceted, multi-angle are the realities on a basic ability and basis.The actual radiation situation from the scene, the layout of equipment and adjustment have occupied the most of the time of whole exposure experiment work often, if can design a kind of general supporting structure, shorten or alleviate the labour intensity and the time of this type of work at the actual arrangement situation of electrical equipment; Simultaneously, uhf sensor and ultrasonic sensor and X ray grenade instrumentation are integrated, device operates convenient.Because high voltage electric equipment has certain threat to personal safety, therefore, give with we inspire this complete integrating device of design; The utility model integrating device has been avoided the direct contact to the internally charged device of high voltage electric equipment, thereby can have been guaranteed personal safety without manually-operated.This device can stretch up and down, all can meet the demands for highly different high voltage electric equipments, is the direction that the insulation of mechanical automation from now on detects development.
