[0002] Cables play a vital role in power systems, especially in high- and ultra-high-voltage power transmission. Cable ends often require caps to protect them from physical damage from the outside environment and from the intrusion of contaminants such as moisture and dust.

[0051] In this example embodiment, a method for intelligently monitoring humidity and oxygen during cable end sealing is first provided. The method can be applied to a terminal device, such as a mobile phone, desktop computer, personal digital assistant, laptop computer, tablet computer, smart watch, or other mobile terminal.
[0052] refer to Figure 1-2 As shown in , the method may include the following steps:
[0053] Step S100: Determining capping control parameters based on the operating parameters of the cable end and the performance parameters of the capping material; wherein the control parameters include a first preset value, a second preset value, and a third preset value, wherein the first preset value includes a humidity target value and an oxygen concentration target value, the second preset value is the maximum safe temperature of the cable end, and the third preset value is the starting temperature;
[0054] Step S200: collecting the operating temperature of the cable end, and performing cyclic high-temperature capping on the cable end through a capping mechanism according to the second preset value and the third preset value, so as to gradually relax the molecular chains of the sealing material and reduce internal stress;
[0055] Step S300: collecting the humidity and oxygen concentration of the environment of the cable end after the high-temperature capping is completed, and performing vacuum dehumidification and deoxygenation on the cable end after the cyclic high-temperature capping through a vacuum mechanism according to the first preset value.
[0056] Among them, the "heating-pause-reheating" cycle is adopted, and multiple temperature cycle operations are performed to ensure the discharge of residual moisture and release of internal stress in the sealing area, thereby optimizing the sealing effect; the heating and pause time are dynamically adjusted according to the material properties and sealing requirements.
[0057] In one embodiment, step 100 specifically includes the following steps:
[0058] Step 110: Determine a second preset value based on a first operating parameter of the cable end, and determine a third preset value based on a performance parameter of the sealing material; wherein the first operating parameter of the cable end includes the maximum safe temperature of the cable end, and the sealing material parameter includes the thermoplastic temperature of the sealing material.
[0059] Step 120: Determine a first preset value based on a second operating parameter of the cable end; wherein the second operating parameter of the cable end includes a standard humidity and oxygen concentration at which the cable end operates.
[0060] In one embodiment, step 200 specifically includes the following steps:
[0061] Step 210: Place the cable end in the working end of the sealing cap structure so that the sensor module in the working end of the sealing cap structure is in close contact with the inner side wall of the sealing cap end, and collect the working temperature of the cable end.
[0062] Step 220: Start the capping structure to perform cyclic high-temperature capping on the cable end; wherein, when the operating temperature of the cable end is greater than the second preset value, the capping structure is paused, and when the operating temperature of the cable end is less than the third preset value, the capping structure is started again.
[0063] Furthermore, the step 220 also includes issuing an alarm when the sensor module detects that the operating temperature of the cable end is greater than the second preset value.
[0064] In one embodiment, step 300 specifically includes the following steps:
[0065] Step 310: Collect the humidity and oxygen concentration of the environment where the cable end is located through the sensor module in the working end of the cap structure.
[0066] Step 320: Control the start and stop of the vacuum mechanism according to the humidity and oxygen concentration of the environment in which the cable end is located; wherein, when the humidity and oxygen concentration of the environment in which the cable end is located, as collected by the sensor module, are both greater than or equal to the first preset value, start the vacuum mechanism to vacuum dehumidify and deoxygenate the cable end; when the humidity and oxygen concentration of the environment in which the cable end is located, as collected by the sensor module, are both less than the first preset value, turn off the vacuum mechanism to complete the vacuum dehumidification and deoxygenation.
[0067] The experimental results show that the reference Figure 3-4 , temperature cycle dehumidification has an advantage in moisture discharge efficiency compared to constant temperature dehumidification. In the initial stage, the humidity of temperature cycle dehumidification drops more rapidly, which shows that the heating-pause cycle operation can more effectively accelerate moisture discharge. After about 400 seconds, the humidity gradually stabilizes, and the final relative humidity of temperature cycle dehumidification stabilizes at around 30%, while constant temperature dehumidification can only stabilize at about 40%. This comparison shows that temperature cycle dehumidification can not only reduce humidity faster, but also achieve lower humidity levels, thereby significantly improving the long-term stability and drying effect of the seal, and is especially suitable for sealing applications with high requirements for humidity control.
[0068] This exemplary embodiment also provides a device for intelligently monitoring humidity and oxygen during the sealing process of the cable end. Figure 5-7 As shown in FIG, the device is composed of a capping mechanism 100, a sensor module 200, a vacuum mechanism 300 and a control module 400, and may include:
[0069] The capping mechanism 100 has a working end that is sleeved on the end of the cable and performs high-temperature capping on the end of the cable when started;
[0070] The sensor module 200 is provided inside the capping mechanism 100 and is used to monitor the operating temperature of the cable end, as well as the humidity and oxygen concentration of the environment in which the cable end is located;
[0071] A vacuum mechanism 300, whose working end is in communication with the interior of the capping mechanism 100, is used to vacuum dehumidify and deoxygenate the cable end when started;
[0072] The control module 400 is connected to the sensor module 200 and the vacuum mechanism 300, and is used to control the start and stop of the capping mechanism 100 according to the working temperature of the cable end; and is used to control the start and stop of the vacuum mechanism 300 according to the humidity and oxygen concentration of the environment in which the cable end is located.
[0073] It should be noted that the capping mechanism 100 has a hot-melt layer, which shrinks when heated at a high temperature to seal the cable end.
[0074] Furthermore, the capping mechanism 100 includes: a capping mechanism main body 110, a first through hole 120 and a second through hole 130; the first through hole 120 and the second through hole 130 are located on the capping mechanism main body 110, the control module 400 is connected to the sensor module 200 inside the capping mechanism 100 through the first through hole 120, and the vacuum mechanism 300 is connected to the inside of the capping mechanism 100 through the second through hole 130.
[0075] The control module 400 has a processing module inside, which is connected to the sensor module 200 via a cable and is used to receive the humidity and oxygen concentration of the environment where the cable end is located collected by the sensor module 200.
[0076] Further, optionally, the vacuum mechanism 300 includes a one-way valve 310, a vacuum pump 320 and a connecting pipe 330; the input end of the one-way valve 310 is penetrated through the second through hole 130 on the sealing mechanism body 110, and the output end is connected to the working end of the vacuum pump 320 through the connecting pipe 330.
[0077] Among them, the input end of the one-way valve 310 is connected to the inside of the hot melt layer of the capping mechanism 100, which is used to vacuum dehumidify the cable end after the high-temperature capping is completed through the one-way valve 310. The one-way valve 310 also ensures that moisture and oxygen cannot enter the heat-sealed cap.
[0078] Furthermore, the sensor module 200 is arranged at the end of the capping mechanism body 110, and includes a humidity sensing unit 210, an oxygen concentration sensing unit 220 and a temperature sensing unit 230; the humidity sensing unit 210 is used to monitor the humidity of the environment in which the cable end is located, the oxygen concentration sensing unit 220 is used to monitor the oxygen concentration of the environment in which the cable end is located, and the temperature sensing unit 230 is used to monitor the working temperature of the cable end; the end of the capping mechanism body is the end of the capping mechanism body away from the working end.
[0079] It should be noted that the humidity sensing unit 210 , the oxygen concentration sensing unit 220 and the temperature sensing unit 230 are integrated into the sensor module 200 , and are all in close contact with the inner side wall of the end of the sealing cap.
[0080] In one embodiment, the sensor module 200 is also used to monitor the operating temperature of the cable end; the control module 400 is also connected to the capping mechanism 100 to control the start and stop of the capping mechanism 100 according to the operating temperature of the cable end.
[0081] Furthermore, the control module 400 is used to close the capping mechanism 100 to suspend high-temperature capping when the operating temperature of the cable end reaches a second preset value during high-temperature capping, and to open the capping mechanism 100 to perform high-temperature capping when the operating temperature of the cable end reaches a third preset value during high-temperature capping.
[0082] It should be noted that, optionally, the control module 400 includes a processing unit and a storage unit, and the second preset value and the third preset value are stored in the storage unit. When the working temperature of the cable end received by the processing unit reaches the second preset value, it means that the working temperature of the cable end has reached the upper limit of the safe temperature that the cable end can withstand, and the capping mechanism 100 is controlled to suspend high-temperature capping to cool down the cable end; when the working temperature of the cable end reaches the third preset value, it means that the working temperature of the cable end is lower than the safe temperature that the cable end can withstand. The specific temperature is set according to the actual situation, and then the capping mechanism 100 is started to continue high-temperature capping, thereby avoiding the problem of excessive temperature affecting the function of the cable end and affecting the capping effect.
[0083] In one embodiment, the alarm module is connected to the control module 400; the control module 400 is also used to send a first alarm signal to the alarm module when the operating temperature of the cable end reaches a second preset value during high-temperature sealing, and the alarm module is used to issue a first alarm when receiving the first alarm signal.
[0084] It should be noted that, optionally, when the working temperature of the cable end received by the processing unit reaches a second preset value, it means that the working temperature of the cable end has reached the upper limit of the safe temperature that the cable end can withstand, and then an audible and visual alarm is issued through the alarm module to prompt the operator to manually pause the capping mechanism 100.
[0085] In one embodiment, the control module 400 is used to turn on the vacuum mechanism 300 to perform vacuum dehumidification and deoxygenation on the cable end after the high-temperature capping is completed when the humidity and oxygen concentration of the environment in which the cable end is located are higher than a first preset value, and to turn off the vacuum mechanism 300 when the humidity and oxygen concentration of the environment in which the cable end is located are lower than the first preset value.
[0086] It should be noted that, optionally, the control module 400 storage unit is also used to store the first preset value, which includes a maximum humidity value and a maximum oxygen concentration; when the humidity or oxygen concentration of the environment in which the cable end is located received by the processing unit exceeds the maximum humidity value or the maximum oxygen concentration, it indicates that the internal environment of the capping mechanism 100 is unstable, and the vacuum pump 320 in the vacuum mechanism 300 is turned on to perform vacuum dehumidification and deoxygenation on the inside of the capping mechanism 100; when the humidity and oxygen concentration of the environment in which the cable end is located received by the processing unit are lower than the maximum humidity value and the maximum oxygen concentration, it indicates that the internal environment of the capping mechanism 100 is stable, and the vacuum pump 320 in the vacuum mechanism 300 is turned off to complete vacuum dehumidification and deoxygenation.
[0087] In one embodiment, the intelligent humidity and oxygen monitoring device during the cable end sealing process further includes: a display module 500 for receiving and displaying the humidity, oxygen concentration and working temperature of the environment of the cable end collected by the sensor module 200.
[0088] Optionally, the humidity and oxygen concentration of the environment in which the cable end is located and the operating temperature of the cable end collected by the sensor module 200 include real-time data and historical data.
[0089] Optionally, the alarm module is connected to the display module 500 , and the alarm information can be displayed through the display module 500 .
[0090] In one embodiment, the control module 400 includes a control panel having function keys such as a start button, a temperature indicator light, an oxygen indicator light, a humidity indicator light, an increase key, a decrease key, and a switch key. All buttons and indicators are connected to the processing unit. Through the control panel, an operator can monitor the operating status of the device in real time and perform corresponding operations according to the prompts of the indicator lights. Among them, the setting mode of the first preset value, the second preset value and the third preset value is switched by the switch key, and the specific numerical value is adjusted by the increase key and the decrease key, and then the cable end humidity and oxygen intelligent monitoring capping device described in this application is started by the main start button to perform high-temperature capping. When the working temperature of the cable end exceeds the second preset value, the temperature indicator light is on, and when the working temperature of the cable end is lower than the third preset value, the temperature indicator light is off. When the temperature indicator light is on, the high-temperature capping can be paused by the capping start button, and after the temperature indicator light is off, the high-temperature capping can be turned on by the capping start button; after the high-temperature capping is completed, the humidity indicator light is on when the humidity inside the capping mechanism body exceeds the first preset value, the humidity indicator light is off when the humidity inside the capping mechanism body is lower than the first preset value, the oxygen indicator light is on when the oxygen concentration inside the capping mechanism body exceeds the first preset value, and the oxygen indicator light is off when the oxygen concentration inside the capping mechanism body is lower than the first preset value. When the temperature indicator light or the oxygen indicator light is on, the vacuum mechanism is started, and when the temperature indicator light and the oxygen indicator light are off, the vacuum mechanism is closed, completing the entire capping process.
[0091] It should be noted that, in an optional embodiment, the capping mechanism is installed at the end of the cable to ensure close contact between the capping device and the end of the cable. Next, the operator manually performs high-temperature capping through the control panel according to the prompt of the temperature indicator light. The high-temperature capping will be preheated in the first stage, and the system will gradually increase the heating power through temperature feedback to avoid uneven capping or damage due to sudden temperature rise. When the temperature reaches the preset preheating temperature, the second stage of formal high-temperature capping operation is carried out. Among them, during the formal high-temperature capping process, when the temperature exceeds the second preset value, the indicator light will sound a warning, prompting the operator to stop heating, and the buzzer will sound a warning to remind the operator to end the heat sealing process to prevent the cap from failing and damaging the cable end due to overheating.
[0092] After the high-temperature capping is complete, the vacuum mechanism is activated to extract moisture, oxygen, and other gases from the cap through the pipe connected to the one-way valve. At this time, the humidity sensor and oxygen sensor monitor the humidity and oxygen concentrations inside the cap in real time. When the humidity and oxygen concentrations fall below a first preset value, the vacuum dehumidification process is complete.
