Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of partial discharge detectors, specifically to a portable partial discharge locator. Background Technology
[0002] The portable partial discharge locator is a lightweight and portable high-voltage equipment testing tool that integrates multiple sensors such as ultrasonic, ultra-high frequency, and transient ground voltage sensors. It can quickly capture discharge signals and accurately locate the discharge source through time difference positioning, echo reflection, and other algorithms. It supports wireless data transmission and real-time analysis and is suitable for on-site inspection, fault diagnosis, and insulation status monitoring of high-voltage equipment in the power, rail transportation, and industrial fields.
[0003] Existing portable partial discharge locators are typically block-shaped with a probe end that is in close contact with the switch cabinet during testing, such as the HYJF-H model. While the bottom of this type of instrument can be held with one hand, the wrist needs to be continuously bent when the probe end is perpendicular to the switch cabinet surface, causing discomfort in the hand while waiting for the test to complete. Furthermore, the instrument's considerable weight further increases the discomfort when holding it. Therefore, a portable partial discharge locator is proposed to solve the above problems.

[0004] The objective of this utility model can be achieved through the following technical solutions:
[0005] A portable partial discharge locator includes a partial discharge locator, and a support mechanism is provided on the outside of the partial discharge locator.
[0006] The support mechanism includes a support frame, on both sides of the top surface of the support frame are symmetrically fixedly connected with internal threaded sleeves, and the inner wall of each internal threaded sleeve is inserted and threaded with a bolt. The middle of the inner wall of each internal threaded sleeve is rotatably connected with a rotating shaft. The top and one side of the rotating shaft are provided with positioning holes, and the inside of the positioning holes is respectively inserted and limited by the lower end of each bolt.
[0007] The support frame has two pivots along its length that are fixedly connected to a handle, with the bottom of the handle extending downward toward the support frame.
[0008] As a further embodiment of this utility model: extension frames are fixedly installed on both sides of the support frame, and the lower ends of the two extension frames are rotatably connected to a support plate. A lifting groove is provided on one side of the inner wall of the support plate, and an insert block is slidably connected inside the lifting groove. The top of the insert block extends to the outside of the support plate, and the top of the insert block is provided with an arc surface.

[0010] As a further embodiment of this utility model: the support plate protrudes outward from the center of the side away from the support frame, and the surface of the support plate abuts against the lower ends of both grips.
[0011] As a further embodiment of this utility model: the inner wall of the support frame is provided with an installation groove, the installation groove is consistent with the support frame in the length direction, anti-slip strips are glued and fixed on both sides of the installation groove, one end of the installation groove extends to the front surface of the support frame, and a push-out is provided in the middle of the rear surface of the support frame, and the interior of the push-out is connected to the interior of the installation groove.
[0012] As a further embodiment of this utility model: a viewing window is provided on the top surface of the support frame, and the interior of the viewing window is connected to the interior of the mounting groove. A slot is provided at the front end of the bottom of the support frame, and the interior of the slot is inserted into the plug block, and the depth of the slot is greater than the height of the arc surface of the plug block.
[0013] As a further embodiment of this utility model: the partial discharge locator includes an instrument body, a detection end is fixedly installed on the front surface of the instrument body, the outer wall of the instrument body is inserted into the inside of the mounting groove, the rear surface of the instrument body abuts against the inner wall of the mounting groove, and the surface of the detection end and the surface of the flipped support plate are located on the same vertical plane, and both sides of the outer wall of the instrument body abut against the anti-slip strip.
[0014] The beneficial effects of this utility model are:
[0015] (1) The present invention provides a detachable support mechanism on the outside of the partial discharge locator. The support frame of the support mechanism can store the partial discharge locator and expose the detection end of the partial discharge locator for easy normal testing. Foldable handles are provided on both sides of the support frame. The handles can be flipped 90 degrees and opened and fixed, so that the operator can hold the handles on both sides with both hands respectively, reducing the difficulty of lifting the instrument during testing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-5 As shown, a portable partial discharge locator includes a partial discharge locator 1, with a support mechanism 2 disposed on the outer side of the partial discharge locator 1. The support mechanism 2 includes a support frame 201, with internally threaded sleeves 205 symmetrically fixedly connected to both sides of the top surface of the support frame 201. Bolts 206 are inserted into and threadedly connected to the inner walls of each internally threaded sleeve 205. A rotating shaft 207 is rotatably connected to the middle of the inner wall of each internally threaded sleeve 205. Positioning holes 208 are provided on the top and one side of the rotating shaft 207, and the interiors of the positioning holes 208 are respectively inserted into and limited by the lower ends of each bolt 206. Two rotating shafts 207 located along the length of the support frame 201 are jointly fixedly connected to a handle 209, the bottom of which extends downwards towards the support frame 201. Figure 3 As shown, after the rotating shaft 207 is rotated 90 degrees clockwise, the positioning hole 208 on the side is aligned with the bolt 206.
[0027] Extension frames 212 are fixedly installed on both sides of the support frame 201. The lower ends of the two extension frames 212 are rotatably connected to a support plate 213. A lifting groove 214 is provided on one side of the inner wall of the support plate 213. An insert block 215 is slidably connected inside the lifting groove 214. The top of the insert block 215 extends to the outside of the support plate 213, and the top of the insert block 215 is provided with an arc surface. Figure 4 , Figure 5 As shown, during the rotation of the support plate 213, the top of the insert 215 will contact the bottom surface of the support frame 201. The curved end can help the insert 215 to transition when it is squeezed, so that the insert 215 retracts into the support plate 213, avoiding interference with the rotation of the support plate 213.
[0028] A lever 217 is fixedly connected to the center of the surface of the insert block 215. The lever 217 passes through and slides through the support plate 213. Springs 216 are fixedly connected to both sides of the bottom surface of the insert block 215. The bottom end of each spring 216 is fixedly connected to the inside of the lifting groove 214. Figure 5 As shown, the spring 216 can be set to a spring with an elastic coefficient of 200-300 N / m. When the insert block 215 retracts into the support plate 213, the spring 216 retracts, and the length of the paddle 217 is less than the thickness of the protruding part of the support plate 213.
[0029] The support plate 213 protrudes outward from the center of the side away from the support frame 201. The protruding surface of the support plate 213 abuts against the lower ends of both grips 209. Figure 1 As shown, the handle 209 in the retracted state can support the support plate 213 in the retracted state, reducing the overall footprint of the support mechanism 2.
[0030] The inner wall of the support frame 201 has a mounting groove 202, which is aligned with the length of the support frame 201. Anti-slip strips 203 are glued and fixed to both sides of the mounting groove 202. One end of the mounting groove 202 extends to the front surface of the support frame 201. A push-out port 204 is provided in the middle of the rear surface of the support frame 201, and the interior of the push-out port 204 is connected to the interior of the mounting groove 202. Figure 1 As shown, the anti-slip strip 203 can be made of rubber, thereby increasing the friction between the instrument body 101 and the support frame 201, thus preventing the instrument body 101 from shaking inside the support frame 201.
[0031] A viewing window 210 is provided on the top surface of the support frame 201, and the interior of the viewing window 210 is connected to the interior of the mounting groove 202. A slot 211 is provided at the front end of the bottom of the support frame 201, and the interior of the slot 211 is inserted into the insert block 215, and the depth of the slot 211 is greater than the height of the arc surface of the insert block 215. Figures 2-5 As shown, after the insert 215 is aligned and inserted into the slot 211, the curved end of the insert 215 cannot be squeezed due to the rotation of the support plate 213, thereby preventing the insert 215 from shifting and coming out of the slot 211.
[0032] The partial discharge locator 1 includes an instrument body 101. A detection end 102 is fixedly mounted on the front surface of the instrument body 101. The outer wall of the instrument body 101 is inserted into the mounting groove 202. The rear surface of the instrument body 101 abuts against the inner wall of the mounting groove 202. The surface of the detection end 102 and the surface of the flipped support plate 213 are located on the same vertical plane. Both sides of the outer wall of the instrument body 101 abut against anti-slip strips 203. Figure 1 As shown, the main body of the instrument 101 is a portable partial discharge locator of model HYJF-H.
[0033] The working principle of this utility model:
[0034] The instrument body 101 can be inserted into the support frame 201 along the mounting groove 202. The anti-slip strip 203 abuts against the side of the instrument body 101 to prevent the instrument body 101 from sliding relative to the support frame 201. During measurement, the handles 209 on both sides can be flipped outward to open. After rotating 90 degrees, the positioning hole 208 is aligned with the bolt 206. Then, the bolt 206 is screwed into the internal thread sleeve 205. The bolt 206 falls down and is inserted into the positioning hole 208. At this time, the handle 209 remains fixed relative to the support frame 201.
[0035] Secondly, the support plate 213 is flipped down to open. After the support plate 213 is perpendicular to the support frame 201, the insert 215 is aligned with the slot 211. Thus, under the push of the spring 216, the insert 215 can be lifted and inserted into the slot 211. Then, the support plate 213 is fixed relative to the support frame 201, and the outer surface of the support plate 213 and the surface of the probe end 102 are located on the same vertical plane. During the test, the side of the instrument body 101 close to the probe end 102 abuts against the surface of the switch cabinet. The support plate 213 increases the support area of the whole device and the surface of the switch cabinet.
[0036] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
