Description

Technical Field

[0001] The invention relates to the technical field of cable discharge detection, in particular to a portable cable partial discharge detection device. Background Art

[0002] Cable partial discharge refers to the discharge phenomenon that occurs in the local area of ​​cable insulation. This discharge may cause cable insulation breakdown, equipment damage or even fire and other serious accidents. Therefore, it is necessary to detect cable partial discharge, and discharge detection equipment is needed during the detection.

[0003] There are many ways to perform discharge detection equipment. Among them, thermal imaging is to determine whether there is partial discharge by measuring the temperature distribution in the insulating medium. When there is partial discharge in the insulating medium, local heat will be generated, causing the temperature distribution in the insulating medium to change. By analyzing the images of these temperature changes, it can be determined whether there is a partial discharge phenomenon.

[0004] When traditional cable partial discharge detection equipment is in use, the laying length of the cable is often relatively long. Therefore, when partial discharge detection is required, for the safety of cable use, it is often necessary to detect cables of all lengths. Traditional detection equipment requires a handheld device to scan the outer wall of the cable, which is very inconvenient when scanning and detecting some longer cables. When the cable is in use, its outer wall will be affected by the external environment, resulting in a layer of dust or other debris attached to the outer wall of the cable. At this time, the outer wall of the cable is directly scanned.

When there is local discharge in the insulating medium of the cable 1, local heat will be generated, causing the temperature distribution in the insulating medium to change. By analyzing the images of these temperature changes, it can be determined whether there is a local discharge phenomenon.

[0046] In a preferred embodiment: the outer wall of the auxiliary wheel 303 contacts the outer wall of the cable 1, the outer wall of the driving belt 305 away from the end of the driven rod 302 is rollingly connected to the outer wall of the driving gear 304, the outer wall of the driving gear 304 and the outer wall of the driven gear 403 are meshed with each other, and the outer wall diameter of the driving gear 304 is larger than the outer wall diameter of the driven gear 403.

Since the outer wall of the driving gear 304 is meshed with the outer wall of the driven gear 403, the driving of the cleaning rod 402 is realized.

[0048] In a preferred embodiment: brushes are installed on the outer walls of the upper cleaning roller 408 and the lower cleaning roller 409, the end of the drive chain 407 away from the upper sprocket 404 is meshed with the outer wall of the lower sprocket 406, and the outer wall shape of the support frame 401 matches the outer wall shape of the cable 1.

[0049] In the above structure, by providing the upper cleaning roller 408 and the lower cleaning roller 409 on the outer wall of the cleaning rod 402, when the auxiliary wheel 303 rotates, the cleaning rod 402 can be driven, and when the cleaning rod 402 rotates, the lower sprocket 406 can be driven under the action of the driving chain 407, so that the lower sprocket 406 and the upper cleaning roller 408 rotate on the outer wall of the cable 1, and the outer wall of the cable 1 is brushed, and the support frame 401 moves with the movement of the moving component 2, and the outer wall of the support frame 401 can scrape the outer wall of the cable 1, so that the outer wall of the cable 1 is kept in a cleaner state.

[0050] In a preferred embodiment: the outer wall of the cleaning rod 402 passes through the inner cavity of the mounting frame 301 and the supporting frame 401 respectively, and driven gears 403 are installed at both ends of the outer wall of the cleaning rod 402, and the outer wall shape of the upper cleaning roller 408 and the lower cleaning roller 409 matches the outer wall shape of the cable 1.

[0051] In the above structure, by passing the outer wall of the cleaning rod 402 through the inner cavity of the mounting frame 301, the outer wall of the driven gear 403 can mesh with the outer wall of the driving gear 304, so that when the auxiliary wheel 303 rotates, the driving gear 304 can be driven to rotate, and the cleaning rod 402 can be driven under the action of the driving gear 304 and the driven gear 403 to realize the rotation of the upper cleaning roller 408 and the lower cleaning roller 409.

[0052] In a preferred embodiment, a movable hole is formed in the inner cavity of the moving block 206 , and the inner wall diameter of the movable hole is equal to the outer wall diameter of the connecting rod 203 .

[0053] In the above structure, by setting the connecting rod 203 on the top of the moving component 2 and the moving block 206 on the outer wall of the connecting rod 203, the moving block 206 will move along the outer wall of the connecting rod 203 under the elastic force of the driving spring 205, so that the outer wall of the driving roller 208 fits more closely with the outer wall of the cable 1, and the driving roller 208 can be better driven under the action of the driving motor 207.

[0054] Working principle: during the use of the above-mentioned device, when it is necessary to perform partial discharge detection on the cable 1, the cable 1 is passed through the inner cavity of the moving component 2, so that the moving component 2 can be installed on the outer wall of the cable 1, and the driving motor 207 is started under the action of the controller. Under the action of the driving motor 207, the driving roller 208 can be driven to rotate. Since the outer wall of the driving roller 208 fits the outer wall of the cable 1, the moving component 2 can be driven under the action of the driving roller 208, so that the moving component 2 moves along the outer wall of the cable 1. When the moving component 2 moves along the outer wall of the cable 1, the controller The controller starts the infrared thermal imager 2012, and the outer wall of the cable 1 is scanned under the action of the infrared thermal imager 2012, and the temperature range on the outer wall of the cable 1 is detected to find suspicious heating points on the outer wall of the cable 1, thereby realizing the detection of discharge on the outer wall of the cable 1. In the process of the movement of the moving component 2, the mounting frame 301 installed in front of the moving component 2 and the driven rod 302 set on the outer wall of the mounting frame 301, along with the movement of the moving component 2, the auxiliary wheel 303 can rotate under the push of the moving component 2, and the power is transmitted to the outer wall of the driving gear 304 under the action of the driving belt 305. Since the outer wall of the driving gear 304 and the outer wall of the driven gear 403 are meshed with each other, the cleaning rod 402 rotates in the inner cavity of the support frame 401. During the rotation of the cleaning rod 402, the cleaning roller 408 rotates on the outer wall of the cable 1, and the rotation direction of the auxiliary wheel 303 is the same as that of the driving gear 304. However, under the action of the driving gear 304 and the driven gear 403, the rotation direction of the cleaning rod 402 can be opposite to that of the auxiliary wheel 303, so that when the lower sprocket 406 and the upper cleaning roller 408 rotate on the outer wall of the cable 1, their rotation direction can be opposite to the moving direction of the cable 1. On the contrary, the outer wall of the cable 1 can be cleaned, and when the support frame 401 moves, the outer wall of the support frame 401 will scrape the outer wall of the cable 1, and the outer wall of the cable 1 can be cleaned under the action of the lower sprocket 406, the upper cleaning roller 408 and the support frame 401, ensuring that the infrared thermal imager 2012 in the inner cavity of the No. 3 scanning chamber 2011, the No. 1 scanning chamber 209, and the No. 2 scanning chamber 2010 is affected by the debris attached to the outer wall of the cable when performing a temperature scan on the outer wall of the cable 1, thereby obtaining more accurate temperature data and better determining whether there is local discharge in the conductor in the inner cavity of the cable.
