Problems solved by technology

[0003] Ultrasonic testing of conventional high-voltage pillar porcelain insulators is mostly manual ultrasonic testing, which is limited by the proficiency, technical level and experience of the testing personnel. The same testing object and different testing personnel may have large differences in testing results, which will cause missed testing and false positives. false detection
Moreover, for substations, it is necessary to detect a large number of pillar porcelain insulators in a short period of time, and the detection speed and efficiency are particularly important, while conventional manual detection cannot meet the requirements
At the same time, some pillar porcelain insulators have a small space for detection, and manual detection will be very inconvenient.
[0004] At the same time, for some ultrasonic detectors with ultrasonic imaging function, manual detection is used for ultrasonic imaging, because there is no matching scanning device with stable contact and uniform speed, it cannot truly reflect the advantages of ultrasonic imaging

Embodiment 1

[0026] figure 2 Shown is a structural diagram of an insulator scanning device. As shown in the figure, the scanning device includes: a plurality of chain links 204 and a locking buckle 205, the plurality of chain links 204 are connected as a chain and the locking buckle 205 connects the two ends of the chain to form the chain rotating ring. Such as image 3 Shown is a schematic structural diagram of a pillar insulator, the insulator scanning device of this embodiment is set between the first shed 301 and the cast iron flange 302 of the pillar insulator through the above-mentioned chain rotating ring, as shown in image 3 The location shown in 303. The chain link 204 has a roller 206, and locks the rotating ring to the post insulator through a locking buckle 205, such as Figure 4 A schematic diagram of the structure of the locked scanning device is shown. The rolling friction between the chain rotating ring and the post insulators is achieved by rollers 206 . The number ...

Embodiment 2

[0038] Such as Figure 11 As shown, the embodiment of the present invention also discloses an insulator scanning system, which includes: an ultrasonic detector 802 , an insulator scanning device 801 and a rotation control device 803 .

[0039] The insulator scanning device 801 includes: a rotating mechanism, an ultrasonic probe and a locator. The rotating mechanism is composed of a motor, a transmission unit and a rotating ring. The rotating ring is used to be set on the post insulator. rotate. The ultrasonic probe is installed on the rotating ring, and is used to rotate and detect the defect of the post insulator and output a detection signal; the locator, installed on the rotating ring, is used to record the rotational displacement of the ultrasonic probe and output a displacement signal. Its structure is the same as that of the insulator scanning device in Embodiment 1, and will not be repeated here.

[0040] Such as Figure 12 As shown, the rotation control device 80 in...

Abstract

The invention discloses an insulator scanning device. The device comprises a rotation mechanism, an ultrasonic probe and a positioner, wherein the rotation mechanism consists of an electric motor, a transmission unit and a rotation ring; the rotation ring is sleeved on a post insulator; the electric motor drives the rotation ring to axially rotate along the post insulator through the transmissionunit; the ultrasonic probe is arranged on the rotation ring and is used for rotationally detecting the defect of the post insulator and outputting a detection signal; and the positioner is arranged on the rotation ring and is used for recording the rotational displacement of the ultrasonic probe and outputting a displacement signal. The insulator is automatically scanned by the device, and detection data obtained by the device has high reliability, and continuity, and is convenient to store and analyze.

Description

technical field [0001] The invention relates to a scanning device for scanning insulators, in particular to a scanning device and system for insulators. Background technique [0002] In order to ensure the safe operation of the power grid, it is necessary to detect the pillar porcelain insulators in the power grid. At present, ultrasonic testing is mostly used for the detection of pillar porcelain insulators. [0003] Ultrasonic testing of conventional high-voltage pillar porcelain insulators is mostly manual ultrasonic testing, which is limited by the proficiency, technical level and experience of the testing personnel. The same testing object and different testing personnel may have large differences in testing results, which will cause missed testing and false positives. Check and error check. Moreover, for substations, it is necessary to detect a large number of post porcelain insulators in a short period of time, and the detection speed and efficiency are particularly ...
