Problems solved by technology

[0003] The existing partial discharge ultrasonic detection requires the operator to hold the sensor for a long time for detection, which is easy to make the operator fatigued and deformed, which in turn leads to inaccurate test results. At the same time, it increases the risk of operation and cannot meet the needs of actual use. The existing partial discharge ultrasonic detection has the disadvantages of manual testing and low detection accuracy, and it is difficult to be popularized and applied

Abstract

The invention discloses a partial discharge ultrasonic detection device, belongs to the technical field of ultrasonic detection, and solves the problems of manual test and low detection precision in the existing partial discharge ultrasonic detection. The device has the technical key points that the partial discharge ultrasonic detection device comprises a base, universal wheels are pushed to facilitate movement of the device, a suction cup is in contact with a to-be-detected shell, an electric telescopic rod drives a rack to stretch out and draw back to enable a cam to rotate, so that a piston plate is subjected to pressure suction, an annular magnet reinforces stability, a first motor is started to drive connecting bases to get close to and get away from each other, the position of an ultrasonic sensor is conveniently adjusted, and pitching adjustment detection of the ultrasonic sensor is conveniently achieved through a hinge base and an air cylinder; a second motor is started to drive a lifting column to drive the ultrasonic sensor to perform lifting adjustment in the height direction, a third motor is started to drive a lifting base to drive the ultrasonic sensor to perform rotation detection under the action of a connecting shaft and a sliding block, and the device has the advantages of saving labor and being high in detection precision.

Description

technical field [0001] The invention relates to the field of ultrasonic detection, in particular to a partial discharge ultrasonic detection device. Background technique [0002] Partial discharge refers to the discharge phenomenon that occurs in the local area of ​​the insulation structure of the power equipment under the action of a sufficiently strong electric field. Although this kind of partial discharge will only lead to partial breakdown of the insulation structure and local short circuit, and no penetrating breakdown of the insulation between the conductors of the power equipment, each partial discharge will have some impact on the insulating medium. In addition, slight partial discharge has little effect on the insulation of power equipment, and the insulation strength drops slowly, while strong partial discharge will make the insulation strength drop quickly. Therefore, when the partial discharge reaches and exceeds a certain level, it will cause damage to the tra...
