Description

Technical Field

[0001] This utility model relates to the field of cable insulation layer testing, and in particular to a cable insulation layer thickness testing device. Background Technology

[0002] In power transmission and distribution systems, cables are important carriers of electrical energy, and the stability and reliability of their performance are directly related to the safe operation of the entire power system. The cable insulation layer, as the core component of the cable, acts like a solid barrier, mainly undertaking the important mission of isolating the conductor from the external environment, preventing current leakage, and resisting the erosion of external physical and chemical factors.

[0003] The cable insulation thickness testing fixture disclosed in Publication No. CN215984462U is characterized by including a base, a control switch, a slide rail, a slider, a cable fixing mechanism, a drive device, and a cable thickness detection mechanism. This device, through the cable fixing mechanism, can achieve overall fixation of the sampled cable. Simultaneously, through the horizontal movement of the cable fixing mechanism, the digital thickness gauge of the cable thickness detection mechanism can detect the insulation layer of the entire sampled cable. However, this device has a relatively limited function, only capable of detecting the thickness of the cable insulation layer, and cannot perform aging and tensile testing on the cable insulation layer. It is difficult to comprehensively evaluate the quality and performance of the cable insulation layer. In actual testing, additional testing equipment with different functions is required, increasing testing costs and affecting testing efficiency.

[0004] Therefore, it is necessary to design a cable insulation thickness testing device that can perform aging, tensile, and thickness testing or single-item testing on cable insulation layers, achieving a combination of multiple functions, improving testing efficiency, comprehensiveness, and reliability, and reducing testing costs. Utility Model Content

Detailed Implementation

[0019] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0020] A cable insulation thickness detection device, such as Figures 1-4As shown, the device includes a testing chamber 1, a first electric push rod 2, a testing slide 3, a first guide rod 5, a thickness measuring instrument 9, a third electric push rod 10, a testing assembly, and a fixing assembly. The testing chamber 1 has a rotating door on its right front for easy sealing during testing. The testing chamber 1 has a display screen on its upper left for displaying testing data. The first electric push rod 2 is connected to the inner front of the testing chamber 1. The first electric push rod 2 and the processor are electrically connected via a control module. The telescopic end of the first electric push rod 2 is connected to the testing slide 3. The inner left and right sides of the testing chamber 1 are both connected to the first guide rod 5, which are slidably connected to the testing slide 3. The inner upper front of the testing chamber 1 is connected to the third electric push rod 10. The third electric push rod 10 and the processor are electrically connected via a control module. The telescopic end of the third electric push rod 10 is connected to the thickness measuring instrument 9. The testing chamber 1 is equipped with a testing assembly for aging and tensile testing of the cable insulation layer. A fixing assembly for clamping and fixing the cable insulation layer is provided between the testing slide 3 and the testing assembly.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, the detection assembly includes an ultraviolet lamp 4, a second electric push rod 6, and a tension sensor 7. The ultraviolet lamp 4 is connected to the upper inner side of the detection chamber 1, and the second electric push rod 6 is connected to the upper right side of the detection slide 3. The second electric push rod 6 and the processor are electrically connected through a control module, and the tension sensor 7 is connected to the telescopic end of the second electric push rod 6.

[0022] like Figure 3 and Figure 4 As shown, the fixing assembly includes a sliding block 8, a second guide rod 11, a fixing block 12, a clamping block 13, and an adjusting screw 14. The sliding block 8 is connected to the left side of the tension sensor 7, and the sliding block 8 is in contact with the detection slide 3. The fixing block 12 is connected to the upper left side of the detection slide 3. The fixing block 12 is connected to the right side of the fixing block 12, and two second guide rods 11 are connected to it. The second guide rods 11 are all slidably connected to the sliding block 8. The second guide rods 11 are all T-shaped to facilitate guidance. The clamping blocks 13 are slidably connected to both the sliding block 8 and the fixing block 12. The clamping blocks 13 are all threadedly connected to the adjusting screw 14.

[0023] When it is necessary to test the thickness of cable insulation, this device can be used. The test chamber 1 is brought into contact with the ground. The chamber door is then opened by rotating it, and the clamping block 13 is pulled to move. The cable insulation sample is then placed on the sliding block 8 and the fixing block 12. The clamping block 13 is then pushed in the opposite direction to move and reset, contacting the cable insulation sample. The adjusting screw 14 is then rotated to move and fix the sample. This allows for the clamping and fixing of cable insulation of different thicknesses for testing, preventing cable insulation displacement, improving testing stability, and providing flexibility. After fixing, the chamber door is closed by rotating it. The processor then activates the first electric push rod 2 via the control module. The first electric push rod 2 drives the test slide 3 to move along the first guide rod 5, causing the sliding block 8, fixing block 12, and clamping block 13 to move, moving the cable insulation to the underside of the ultraviolet lamp 4. The first electric push rod 2 is then turned off, and the ultraviolet lamp 4 is activated to irradiate the cable insulation, thus performing aging testing on the cable insulation. After testing, the ultraviolet lamp 4 is turned off.

[0024] Next, the first electric push rod 2 operates in reverse, causing the sliding block 8, fixed block 12, and clamping block 13 to move and reset in the opposite direction, thus moving the cable insulation layer in the opposite direction and resetting it. Then, the third electric push rod 10 is activated, causing the thickness measuring instrument 9 to move and contact the cable insulation layer, thereby detecting the thickness of the cable insulation layer. After the detection is completed, the third electric push rod 10 operates in reverse, causing the thickness measuring instrument 9 to move and reset in the opposite direction. Then, the second electric push rod 6 is activated, causing the tension sensor 7 to move back and forth, causing the sliding block 8 to move back and forth along the second guide rod 11, thereby performing repeated tensile tests on the cable insulation layer. The second guide rod 11 is T-shaped, and the tension sensor 7 simultaneously monitors the applied tension. After the test is completed, turn off the second electric push rod 6. The test data will be displayed on the screen. Then, turn the door to open and turn the adjusting screw 14 to move it away from the cable insulation layer. Then, move the cable insulation layer to remove it, or install the cable insulation layer on the sliding block 8 and the fixed block 12. Move the cable insulation layer by moving the test slide 3 to perform a single test. After the test, remove the cable insulation layer and replace it with a new cable insulation layer for the next test. This allows for single-item testing, which can perform aging, tensile, and thickness tests on the cable insulation layer or perform single-item tests. This achieves a combination of multiple functions, improves testing efficiency, comprehensiveness, and reliability, and reduces testing costs. Then, continue to repeat the above operation to test the next cable insulation layer.
