[0002] In fields like power transmission, cables serve as a bridge between information and energy. Their superior and stable performance is directly linked to the reliable operation of the entire system. As the core protective layer in the cable structure, the cable's water-blocking buffer layer must provide the necessary mechanical support and cushioning in complex and changing external environments. However, as cable applications continue to expand, the challenges faced by the water-blocking buffer layer, such as high temperatures, corrosion, and mechanical stress, are becoming increasingly severe, necessitating an urgent need for performance evaluation and improvement.

[0003] Although the existing cable water-blocking buffer layer simulation ablation test equipment can simulate the ablation process of cables in actual use to a certain extent, it still has shortcomings in many aspects. First, the test environment is the basis for ensuring the test. Deviations in the gas composition, temperature, and humidity in the environment may mislead the performance evaluation of the cable water-blocking buffer layer, causing R&D personnel to make incorrect judgments in subsequent designs. Secondly, the existing equipment performs poorly in terms of flexibility and adaptability of test configuration. Faced with diverse test requirements, the limited adjustment range of parameters such as tension and temperature makes it difficult for R&D personnel to conduct a comprehensive and in-depth evaluation of the cable water-blocking buffer layer, which restricts the further innovation and development of cable technology.

[0035] Please refer to Figure 1-Figure 7 In an embodiment of the present invention, a cable water-blocking buffer layer simulated ablation test device is provided, comprising a voltage loop component and an ablation test component 5 connected to the voltage loop component, wherein the ablation test component 5 comprises:

[0036] a positioning plate 56 for positioning one end of the test cable;

[0037] A lead screw 51 having a movable end on which a base 52 is mounted;

[0038] A spacing adjustment assembly 53 having a plurality of spacing adjustment ends for synchronously adjusting spacing, wherein a cable drum 54 is mounted on each spacing adjustment end. When the test cable passes through the corresponding cable drum 54, the cable drum 54 positions the test cable;

[0039] a parameter adjustment component 55 , which is mounted on the base 52 and is used to provide a test environment gas for the cable drum 54 ;

[0040] Wherein, the spacing adjustment component 53 includes:

[0041] A mounting base 531 fixed on the base 52;

[0042] A limiting rod 532 is fixed to the mounting seat 531 , and a plurality of sliding seats 533 are slidably provided on the limiting rod 532 ;

[0043] The air distributor 534 serving as the spacing adjustment end of the spacing adjustment assembly 53 is correspondingly fixed below the slide 533 , and the cable drum 54 is installed below each of the air distributors 534 ;

[0044] The synchronous adjustment component is disposed below the slide 533 and is driven by a cylinder 535 . The cylinder 535 is fixed to one side of the mounting base 531 .

[0045] The implementation includes the following steps:

[0046] Step 1: Place one end of the test cable on the positioning plate 56 to ensure that one end of the test cable is positioned (such as by using bolts), and pass the test cable through the cable barrel 54 to further position the test cable.

[0047] Step 2: By driving the synchronous adjustment component and the cylinder 535, the slide 533 slides on the limit rod 532, thereby driving the air distributor 534 and the cable drum 54 to move, and then adjusting the spacing between each cable drum 54, so as to subsequently evaluate the impact of different spacing conditions on the ablation performance of the cable water-blocking buffer layer.

[0048] Step 3: Use the parameter adjustment component 55 to provide the test cable in the cable barrel 54 with the required ambient gas for the test. The temperature and humidity of the ambient gas are adjustable to facilitate subsequent evaluation of the impact of different environmental conditions on the ablation performance of the cable's water-blocking buffer layer.

[0049] Step 4: Under the action of the voltage loop component, the test cable begins to be energized and the ablation test is performed.

[0050] Step 5: Record the cable's ablation rate, ablation morphology and other data. By analyzing these data, we can further understand the performance characteristics of the cable's water-blocking buffer layer and evaluate the performance of the cable's water-blocking buffer layer.

[0051] It should be explained that one end of the test cable is fixed to the positioning plate 56 to ensure its stable position. The other end is adjusted relative to the other end by the spacing adjustment assembly 53, thereby adjusting the spacing of the test cables at that end. Although this adjustment may cause the test cables to be non-perfectly parallel (due to one end being fixed), in general, the impact of this non-parallelism on test results is acceptable.

[0052] In addition, a base 52 is mounted on the movable end of the lead screw 51 . The base 52 is pulled by the rotation of the lead screw, thereby applying an axial force to the test cable fixed in the cable barrel 54 .

[0053] The application of this axial force simulates the tension that the cable may be subjected to in actual use, so as to subsequently evaluate the impact of different tensions on the ablation performance of the cable's water-blocking buffer layer.

[0054] In this embodiment, the synchronous adjustment assembly includes a plurality of X-shaped hinged rods 536 , and the hinged rods 536 are further connected to the slide 533 using a connecting seat 538 . The hinged rod 536 located in the middle is positioned on the mounting seat 531 using a center seat 537 .

[0055] In this embodiment, the voltage circuit component includes a voltage source 1, a fuse 2, an ammeter 3, a voltmeter 4 and a transformer 6, wherein the input end of the transformer 6 is connected to the voltage source 1, the output end of the transformer 6 is connected to the ablation test component 5 via the fuse 2, the voltmeter 4 is connected in parallel to the two ends of the ablation test component 5, and the ammeter 3 is connected in series to one side of the ablation test component 5.

[0056] In this embodiment, the parameter adjustment component 55 includes a pump air module 551, a temperature control module 552, and an air supply pipe 553 connected in series in sequence, wherein the internal humidity of the air supply pipe 553 is also controlled by a humidification module 554, and the air supply pipe 553 is correspondingly connected to the air distribution seat 534.

[0057] The gas pump module 551 is responsible for generating and delivering the gas required for the test. The gas flow and pressure can be controlled by a regulating valve of the gas pump module 551 to ensure the stability and accuracy of the gas supply during the test. The gas pump module 551 can be an air pump.

[0058] The temperature control module 552 is used to adjust the temperature of the gas. It can control the temperature of the gas through a heating or cooling system to simulate various temperature conditions that may be encountered in actual use. The temperature control module 552 can be a thermostat.

[0059] In addition, the humidification module 554 is used to control the humidity of the gas inside the gas supply pipe 553. It can add water vapor to the gas through spraying, steam or other means to simulate various humidity conditions that may be encountered in actual use.

[0060] The working process is as follows:

[0061] Step 1: The gas pumping module 551 pumps gas according to the test requirements.

[0062] Step 2: The temperature control module 552 adjusts the temperature of the pumped gas to ensure the constancy and accuracy of the gas temperature during the test.

[0063] Step 3: The humidification module 554 adds water vapor to the gas according to the test requirements to adjust the humidity of the gas.

[0064] The gas processed by the gas pump module 551 , the temperature control module 552 and the humidification module 554 is transported to the gas distributor 534 through the gas supply pipe 553 , and then supplied to the test cable in the cable barrel 54 .

[0065] The precise control of the pump module 551, temperature control module 552, and humidification module 554 allows precise regulation of the pressure, temperature, and humidity of the test environment. This helps to more accurately simulate various environmental conditions that may be encountered in actual use, thereby improving the accuracy and reliability of the test.

[0066] In this embodiment, a main channel 5341 is embedded in the gas distribution seat 534 , and the bottom of the main channel 5341 is connected to three branch channels 5342 . The branch channels 5342 are connected to the cable tube 54 , and the main channel 5341 is provided with test environment gas by the parameter adjustment component 55 .

[0067] There are three branch channels 5342 connected from the bottom of the main channel 5341 , which are located at different positions of the gas distribution seat 534 . These branch channels 5342 evenly transport the test environment gas into the cable barrel 54 .

[0068] Two symmetrically arranged stabilizing rings 542 are embedded in the cable drum 54 , and the three branch channels 5342 are all located between the two stabilizing rings 542 .

[0069] The main function of the stabilizing ring 542 is to support the test cable and prevent it from shaking or deflecting in the cable barrel 54.

[0070] The provision of the stabilizing ring 542 can ensure that the test cable maintains a stable position during the ablation test, thereby improving the accuracy of the test.

[0071] A locking capsule 541 is embedded in the cable barrel 54 , and the locking capsule 541 is communicated with the diversion channel 5342 located in the middle.

[0072] In addition, a control valve can be independently set on each branch channel 5342.

[0073] After receiving the gas from the diversion channel 5342 , the locking bag 541 will expand and cling to the test cable, thereby locking and fixing the test cable.

[0074] Furthermore, before the test begins, the locking capsule 541 first expands and fits against the test cable to position the test cable. Then, the moving end of the lead screw begins to move, applying an axial tension to the test cable through the base 52 and the cable drum 54.

[0075] Furthermore, heating plates 543 are provided on both sides of the locking capsule 541 , and the heating plates 543 are embedded in the cable barrel 54 .

[0076] The main function of the heating plate 543 is to assist in controlling the gas temperature inside the cable barrel 54 .

[0077] During the test, the heating plate 543 can be turned on or off as needed to adjust the temperature environment inside the cable barrel 54. By accurately controlling the heating power and time of the heating plate 543, auxiliary adjustment of the temperature inside the cable barrel 54 can be achieved.

[0078] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
