Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the partial discharge detection mechanism 100 according to the embodiment of the present invention has the following working principle: when partial discharge occurs inside the electrical device, an ultrasonic signal is generated. The ultrasonic signal is conducted by the local power supply to the electrical equipment enclosure along the insulating medium and the metallic member and propagates through the medium and the gap to the surrounding air. The ultrasonic sensor arranged on the shell of the electrical equipment or near the electrical equipment is coupled to an ultrasonic signal generated by partial discharge, so that the partial discharge condition of the electrical equipment is judged, the surface of a partial discharge detection instrument is required to be parallel and aligned with the surface of the electrical equipment in the detection process, relative displacement cannot be caused, and otherwise misdetection and missing detection can be caused.
As shown in fig. 1 and 2, the partial discharge detection mechanism 100 includes a mounting base 10, a rotating member 20, a telescopic member 30, a detection probe 40, an elastic element 50, and a proximity switch 60.
The mounting base 10 is used to mount the partial discharge detection mechanism 100 to an inspection robot body (not shown).
The rotating unit 20 is rotatable with respect to the mounting base 10, and includes a rotating arm 21, a rotating shaft 22, and a rotation driving motor 23.
The rotating arm 21 is fixedly connected with the mounting base 10. In the present embodiment, the rotating arm 21 is made of a sheet metal.
The rotation shaft 22 is accommodated in the rotation arm 21 and rotatably provided on the mounting base 10.
The rotation driving motor 23 is disposed outside the rotating arm 21, and is connected to the rotating shaft 22 for driving the detecting probe 40 to rotate relative to the mounting base 10.
The telescoping assembly 30 cooperates with the rotating assembly 20 to enable the partial discharge detection mechanism 100 to move in two dimensions. The telescopic assembly 30 comprises a telescopic driving motor 31, a driving wheel 32, a synchronous belt 33, a driven wheel 34, a transmission linear guide rail 35 and a connecting rod 36.
The telescopic driving motor 31 is provided outside the rotary arm 21 for providing a driving force for detecting the extension and contraction of the probe 40.
The driving wheel 32 is connected with the telescopic driving motor 31, and forms a set of synchronous belt mechanism together with the synchronous belt 33 and the driven wheel 34.
The driving linear guide 35 is fixed to the rotary arm 21.
The link 36 can move along the driving linear guide 35 to extend or retract from the rotary arm 21. One end of the connecting rod 36 is connected with the synchronous belt 33 through a metal pressing sheet, so that the connecting rod 36 can be extended and retracted by controlling the forward rotation and the reverse rotation of the driving wheel 32. It can be understood that the operation of the detecting probe 40 is sufficiently smooth due to the driving linear guide 35 as a guide.
The detection probe 40 is used for detecting a partial discharge of the electrical device, and can be extended and retracted and rotated with respect to the mounting base 10 by the extension unit 30 and the rotation unit 20, respectively. The detection probe 40 is fixedly connected with the connecting rod 36 through the elastic element 50, so that the elastic element 50 can adjust the angle of the detection probe 40, and the detection end surface 41 of the detection probe 40 is tightly attached to the electrical equipment, thereby improving the accuracy of detection data.
