Description

Technical Field

[0001] This utility model relates to the field of power safety testing technology, and in particular to an insulating boot testing device. Background Technology

[0002] Insulating boots are widely used in power system maintenance, rail transportation, and high-voltage operations to isolate ground potential and ensure the safety of workers in energized environments. Currently, the insulation performance of insulating boots is primarily tested using the "water testing method." This involves injecting water into the inside of the boot and submerging it in an external water tank, creating conductive liquids inside and outside the boot. By applying pressure, the leakage current or insulation resistance is measured to determine if the insulation performance is up to standard. This testing method has become a standardized procedure and has a certain degree of applicability.

[0003] Currently, the most common testing method for insulating boots is the "water medium method." The main principle involves injecting a certain amount of water inside the insulating boot while simultaneously immersing the boot in an external water tank. Electrodes are inserted into both the inner and outer water tanks, and a high voltage is applied to measure the leakage current or insulation resistance. This method is typically used in conjunction with large-scale insulation testing equipment and is widely applied in laboratories and designated testing centers to assess whether the safety performance of insulating boots meets standards.

[0004] Existing methods for testing water in insulating boots are feasible in laboratories, but they are inefficient and pose safety hazards due to manual operation involving steps such as filling and draining water and inserting electrodes. Furthermore, they are difficult to conduct standardized testing outdoors or in complex field conditions. Therefore, this application proposes an insulating boot testing device that effectively solves the technical problems of low efficiency, poor safety, and insufficient adaptability to field conditions in existing technologies.

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, one objective of this invention is to provide an insulating boot testing device, comprising: a test container for containing an insulating boot to be tested; a first airbag, an inflatable structure for attaching to the outer surface of the insulating boot in an inflated state; a second airbag, an inflatable structure for attaching to the inner surface of the insulating boot in an inflated state; a first conductive layer disposed on the outer surface of the first airbag for forming electrical contact with the outer surface of the insulating boot; a second conductive layer disposed on the outer surface of the second airbag for forming electrical contact with the inner surface of the insulating boot; wherein the interface between the first conductive layer and the outer surface of the insulating boot is called the outer conductive bonding surface, and the interface between the second conductive layer and the inner surface of the insulating boot is called the inner conductive bonding surface; a high-voltage detection system electrically connected to the first conductive layer and the second conductive layer respectively, for applying high voltage when the first conductive layer and the second conductive layer are in contact, to detect the insulation performance of the insulating boot.

[0006] In one possible implementation, the first airbag and the second airbag are each connected to a separately configured air pump unit via independent air tubes to achieve independent inflation control of the inner and outer airbags. The independent air tube connected to the first airbag is called the first air tube, and the independent air tube connected to the second airbag is called the second air tube.

[0007] In one possible implementation, the first airbag and the second airbag are each equipped with a pressure sensor for real-time acquisition of their respective internal air pressure data. The pressure sensor located in the first airbag is referred to as the first pressure sensor, and the pressure sensor located in the second airbag is referred to as the second pressure sensor.

[0008] In one possible implementation, a control unit is also included, which is used to receive signals from the pressure sensor and to control the air pump unit to perform inflation or deflation operations so that the airbag reaches a predetermined fit.

[0009] In one possible implementation, the high-voltage detection system includes a high-voltage power supply and a current acquisition module, the current acquisition module being used to monitor the leakage current between the two conductive layers of the insulating boot when a high voltage is applied.

[0010] In one possible implementation, the control unit includes a judgment module, which receives the leakage current signal output by the current acquisition module and compares the leakage current signal with a preset current threshold to output a detection result signal indicating whether the insulation performance of the insulating boot is qualified.

[0011] In one possible implementation, a display module is also included for displaying the insulation performance test results and related test parameters in a graphical or numerical manner.

[0012] In one possible implementation, the first conductive layer and the second conductive layer are each made of a flexible conductive rubber material to enhance their adhesion to the surface of the insulating boot and their conductive stability.

[0013] In one possible implementation, the control unit is used to trigger the high-pressure detection system to apply a high-pressure signal when the air pressure of both the first airbag and the second airbag reaches the corresponding preset threshold.

[0014] In one possible implementation, the preset threshold is set according to the airbag structure parameters and the insulating boot morphology parameters, respectively corresponding to the bonding state between the first conductive layer and the outer surface of the insulating boot, and the bonding state between the second conductive layer and the inner surface of the insulating boot.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Based on the above technical solution, the insulating boot testing device of this utility model comprises an inflatable first airbag and a second airbag, which are respectively attached to the outer and inner surfaces of the insulating boot. A first conductive layer and a second conductive layer are disposed on the outer side of the airbags, forming electrical contact with the inner and outer surfaces of the insulating boot, respectively. A high-voltage testing system is electrically connected to the two conductive layers, applying high voltage in the attached state to test the insulation performance of the insulating boot. This structure utilizes the inflation and expansion characteristics of the airbags to achieve flexible adhesion between the conductive layers and the surface of the insulating boot, ensuring uniformity and reliability of electrical contact. Dry testing can be performed without the need for water or other liquid media, making operation simple and the testing process efficient and safe. Compared with traditional water testing methods, this device eliminates manual steps such as water injection, water release, and electrode insertion, significantly improving testing efficiency and ease of use. It is particularly suitable for rapid insulation performance testing in outdoor or field environments, solving the problems of low testing efficiency, poor safety, and insufficient field adaptability in existing technologies.

[0022] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Figure 1 This is a schematic diagram of the structure of the insulating boot detection device provided in an embodiment of the present utility model; Figure 2 for Figure 1 An enlarged schematic diagram of region A in the device shown.

[0024] Please see Figure 1-2 In one possible implementation, the insulating boot testing device includes: a test container 1 for holding the insulating boot to be tested; a first airbag 2, which is an inflatable structure designed to fit tightly against the outer surface of the insulating boot when inflated; a second airbag 3, also an inflatable structure, disposed inside the insulating boot and fitting against the inner surface of the insulating boot when inflated; a first conductive layer 4 disposed on the outer surface of the first airbag 2, capable of forming a stable electrical contact with the outer wall of the insulating boot after the airbag expands; a second conductive layer 5 disposed on the outer surface of the second airbag 3, capable of forming an electrical contact with the inner wall of the insulating boot after the second airbag 3 is inflated; and a high-voltage testing system 6 electrically connected to the first conductive layer 4 and the second conductive layer 5 respectively, applying high voltage when the two conductive layers are in contact with the inner and outer walls of the insulating boot to test the insulation performance of the insulating boot.

[0025] When testing the insulation performance of a pair of insulated boots, the operator first places them completely in the test container 1, ensuring the boots are upright with the opening facing upwards. At this point, the control system activates the air pump, inflating the first airbag 2 and the second airbag 3. The first airbag 2 is located on the outside of the boot, gradually expanding and covering the outer surface of the boot during inflation; the second airbag 3 extends into the boot through the opening, inflating and tightly fitting against the inner surface of the boot. Since the surfaces of the two airbags are respectively equipped with a first conductive layer 4 and a second conductive layer 5, after inflation, these two conductive layers make full contact with the outer and inner walls of the boot, establishing a complete testing circuit.

[0026] Once the testing is ready, the high-voltage detection system 6 is activated, applying a specified DC or AC high voltage (e.g., 10kV) between the first conductive layer 4 and the second conductive layer 5 via the control module. Ideally, a qualified insulating boot will exhibit extremely high dielectric strength, with near-zero current leakage between the two conductive layers. The current detection module in the system collects the leakage current value in real time during this period and transmits the data to the control system for analysis.

[0027] If the insulating boot has internal breakdown, cracks, or material aging, high voltage will create a weak current path between the inner and outer conductive layers. In this case, the current sensor will detect an abnormal leakage value. The control system determines whether the current test is qualified based on a preset threshold and can automatically output the test results, for example, through red / green indicator lights, audible prompts, or numerical displays.

[0028] This process not only simulates the high-voltage working conditions of insulated boots in power operation environments, but also ensures the integrity and uniformity of electrical contact through inner and outer double airbags, eliminating interference factors such as poor human contact or insufficient contact points of clamps, thus making the test results more reliable.

[0029] This implementation effectively solves the problems of uneven contact, difficult positioning, and inaccurate testing in traditional insulating boot testing. The inflatable structure of the first airbag 2 and the second airbag 3 ensures that the conductive layer tightly adheres to the inner and outer surfaces of the boot, improving the accuracy and repeatability of the test. By setting up the high-voltage testing system 6 and applying voltage, the performance of the insulating material can be directly tested, achieving rapid, accurate, and non-destructive testing of insulating boots. The device has a compact structure, is easy to operate, and is suitable for batch testing.

[0030] It is worth noting that the structure of the test container 1 can be adjusted according to the size of different models of insulating boots, and an adjustable or modular design can be adopted to adapt to different specifications of boot bodies; the first airbag 2 and the second airbag 3 can use different flexible materials, such as silicone, thermoplastic elastomers, etc., to improve fit and durability; the conductive layer can also use other conductive flexible materials such as metal-coated fabric or carbon nanotube composite rubber to further enhance conductivity stability; the voltage value applied in the high-voltage detection system 6 can be adjusted according to the test standard to adapt to the testing requirements of insulating boots of different voltage levels.

[0031] Please see Figure 1 In one possible implementation, the first airbag 2 and the second airbag 3 are respectively connected to a separately provided air pump unit 7 through independent air pipes to achieve independent inflation control of the inner and outer airbags.

[0032] In actual testing, to ensure that the conductive layer evenly adheres to both the inner and outer surfaces of the insulating boot, the expansion states of the inner and outer air bladders need to be controlled separately. Therefore, the device design employs a dual-air-path structure, where the first air bladder 2 is connected to the first air pump unit 7, and the second air bladder 3 is connected to the second air pump unit 7. Each air pipe is equipped with an independent control valve. The control system can independently adjust the start / stop time, pressure output, and on / off state of each air pump, thereby achieving separate inflation and deflation of the two air bladders.

[0033] This structure allows operators to set the inflation level of the inner and outer air bladders according to the actual shape of different models, materials, or sizes of insulating boots, avoiding contact failure of the conductive layer or deformation of the boot body due to over-inflation or under-inflation of one air bladder. Air pump unit 7 can be a miniature air pump with pressure feedback control, ensuring a controllable, rapid, and safe inflation process. This independent inflation design improves the flexibility and adaptability of the entire testing process.

[0034] This approach can significantly improve the uniformity of the fit between the airbag and the boot body and the accuracy of pressure control, thereby improving the stability and repeatability of the detected electrical signals and ensuring the scientific validity and reliability of the insulation performance assessment.

[0035] In other implementation variations, pressure regulators or buffer chambers can be configured for each of the two air pump systems to reduce the impact of pressure fluctuations on the bonding state of the conductive layer; the air tubes can be in the form of quick-connect couplings for easy maintenance and replacement; if used in a high-volume testing environment, a centralized air supply system can also be used, with the inflation process of the airbags at each testing station controlled by solenoid valve groups, thereby improving the system integration and automation level.

[0036] Please see Figure 1-2 In one possible implementation, the first airbag 2 and the second airbag 3 are each equipped with a pressure sensor 8 for real-time acquisition of their respective internal air pressure data.

[0037] During the testing process, to ensure a stable fit between the first airbag 2 and the outer surface of the insulating boot, and between the second airbag 3 and the inner surface of the insulating boot, pressure sensors 8 are installed on the first airbag 2 and the second airbag 3, respectively. These pressure sensors 8 can be flexible diaphragm or micro-capacitor structures, embedded in appropriate positions on the inner wall of the airbag without interfering with the airbag inflation function. Each pressure sensor 8 is connected to the control unit 9 via a signal line or wirelessly, transmitting the current air pressure value inside the airbag in real time.

[0038] During the testing process, the control system monitors and records the received air pressure data in real time to determine whether the airbag has reached the preset fitting pressure threshold. If the air pressure of a certain airbag deviates from the target value, the system can issue an alarm or automatically adjust the working status of the corresponding air pump unit 7 until the airbag pressure returns to a reasonable range.

[0039] This structure ensures quantifiable control over the fit between the airbag and the boot during testing, providing a fundamental guarantee for the reliability of subsequent high-pressure testing. It also facilitates the collection of air pressure change data at various stages, aiding in the evaluation of the long-term stability and durability of the airbag system.

[0040] Among them, the pressure sensor 8 can be further integrated with temperature compensation function to adapt to the detection needs in high and low temperature environments; a wireless data transmission module can also be used to make the device structure simpler; for airbags of different sizes, multiple sensors can be set to improve the accuracy of overall air pressure distribution detection and avoid problems such as local air leakage or insufficient fit.

[0041] Please see Figure 1 In one possible implementation, a control unit 9 is also included. The control unit 9 is used to receive signals from the pressure sensor 8 and to control the air pump unit 7 to perform inflation or deflation operations so that the airbag reaches a predetermined fit.

[0042] During the testing of the insulating boots, a control unit 9 is installed as the core coordination module to achieve precise control of the first airbag 2 and the second airbag 3. The control unit 9 is equipped with a signal acquisition interface, a power control module, and an automatic feedback logic loop. It receives signals from the pressure sensors 8 respectively installed on the first airbag 2 and the second airbag 3 to determine in real time whether the inflation status of each airbag has reached the set target value.

[0043] When the internal pressure of one of the airbags falls below a set threshold, the control unit 9 automatically triggers the air pump unit 7 connected to that airbag to begin inflation. When the pressure reaches the upper limit threshold or exceeds the target value, the system controls the relevant solenoid valve or pressure relief unit to open and perform a deflation operation. In this way, the system can dynamically adjust the expansion state of the two airbags, ensuring a stable fit regardless of the shape of the insulating boot.

[0044] Furthermore, the control unit 9 supports multiple operating modes. In fully automatic mode, air pressure control and high-pressure detection are completed automatically; in manual mode, the operator can make fine adjustments according to the actual situation. The entire inflation and deflation process is stably carried out under the unified management of the control unit 9, ensuring the repeatability and accuracy of test conditions.

[0045] The control unit 9 can also integrate a microprocessor to achieve multi-channel parallel control and support functions such as touch screen display, remote control or communication with a host computer; the control logic can preset multiple air pressure configuration files to quickly adapt to different types of insulated boot detection scenarios; to improve system stability, redundant safety mechanisms can be introduced, such as automatic power-off protection or alarm prompt function for abnormal pressure.

[0046] In one possible implementation, the high-voltage detection system 6 includes a high-voltage power supply and a current acquisition module, which is used to monitor the leakage current between the two conductive layers of the insulating boot when a high voltage is applied.

[0047] During the insulation performance testing phase, once the first airbag 2 and the second airbag 3 are respectively attached to the outer and inner surfaces of the insulating boot and form electrical contact with the boot body through the first conductive layer 4 and the second conductive layer 5 configured on their exterior, the high-voltage testing system 6 begins to operate. The high-voltage power supply configured within the system can output a stable and adjustable high-voltage signal (such as DC 10kV). This high-voltage signal is controlled by the control unit 9 to adjust its application time and activation conditions, and is connected to the first conductive layer 4 and the second conductive layer 5 via cables.

[0048] After high voltage is applied, if the insulating boot material is intact and has good insulation performance, no significant current will be generated between the two conductive layers; otherwise, if there are defects such as aging, cracks, or breakdown, a weak current path will be generated. The current acquisition module, as a key component of this system, is composed of high-precision sampling resistors, isolation operational amplifiers, and analog-to-digital conversion circuits. It can reliably detect leakage current signals under high voltage conditions and feed them back to the control unit 9 for processing in real time.

[0049] The system typically has multiple current detection levels to meet testing needs of different voltage levels or detection accuracy requirements. The current values ​​collected during testing can not only be used to determine whether the insulation performance is up to standard, but also to further analyze the material degradation trend, serving as a reference for equipment maintenance and replacement.

[0050] It is worth noting that the high-voltage power supply can use programmable modules to adapt to the insulation testing standards of different countries / regions; the current acquisition module can also use opto-isolated acquisition or wireless acquisition methods to improve electrical safety; in addition, a load regulation module can be introduced to make the system compatible with a wider range of test objects, including different types of wearable protective equipment such as insulating boots and insulating gloves.

[0051] In one possible implementation, the control unit 9 includes a judgment module, which receives the leakage current signal output by the current acquisition module and compares the leakage current signal with a preset current threshold to output a detection result signal indicating whether the insulation performance of the insulating boot is qualified.

[0052] During high-voltage detection, the current acquisition module transmits the real-time monitored leakage current signal to the judgment module inside the control unit 9. This judgment module typically consists of an embedded processor, an A / D conversion circuit, and a logic discrimination program. It can digitize the input analog current signal and compare it with a preset current threshold.

[0053] When the leakage current value is less than or equal to the threshold, the judgment module outputs a "qualified" signal, indicating that the tested insulating boot has good insulation performance; if the leakage current value exceeds the threshold, the system outputs a "unqualified" signal, indicating the presence of an insulation defect. This judgment process is fully automatic, requiring no manual intervention, and can significantly improve detection efficiency and consistency.

[0054] The threshold parameters of the judgment module can be set through the system initialization interface, or multiple judgment criteria can be preset according to different boot types, standards, or usage scenarios to achieve differentiated detection strategies. Simultaneously, this module also has data storage and export functions, allowing historical detection results and corresponding parameters to be archived for easy traceability and statistical analysis.

[0055] The judgment module can also embed fuzzy logic algorithms for boundary value processing to avoid misjudgment of critical states; it can also be combined with other detection dimensions such as airbag pressure data and detection time to achieve comprehensive intelligent judgment; its output signal can drive the display module 10 and can also be transmitted to the central monitoring system or remote platform through the communication interface to realize networked and centralized detection management.

[0056] Please see Figure 1 In one possible implementation, it also includes a display module 10 for displaying the insulation performance test results and related test parameters in a graphical or numerical manner.

[0057] To improve the visualization and ease of operation of the testing device, the system is equipped with a display module 10, which is typically an LCD screen or a color touch screen. This module can receive key parameters and judgment results throughout the testing process via the data interface of the control unit 9. The displayed content includes, but is not limited to: current airbag pressure value, detection voltage value, leakage current value, detection judgment result (pass / fail), and corresponding timestamp.

[0058] After a test is completed, the display module 10 automatically displays the test results output by the judgment module graphically, for example, using color indicators (green for pass, red for fail), and simultaneously displays the specific value of the leakage current in digital form, making it easy for the operator to intuitively judge the reliability of the results. If equipped with touch functionality, users can also view historical test records, switch display modes, export test data, or set system parameters through the operation interface.

[0059] Display module 10 supports multilingual interface selection to meet the needs of different countries and regions; the interface layout is simple and clear, supporting the operating habits of daily maintenance personnel and non-professionals.

[0060] The display module 10 can be integrated with the control unit 9 into a single operating interface; alternatively, an external display or industrial tablet can be used to enhance flexibility. For automated inspection production lines, the inspection data can be displayed to a host computer platform via a wireless module or bus interface for centralized monitoring and management. This module also supports customized software interface development to adapt to specific industry standards or customer needs.

[0061] In one possible implementation, the first conductive layer 4 and the second conductive layer 5 are respectively made of flexible conductive rubber material to enhance their adhesion to the surface of the insulating boot and their conductive stability.

[0062] In this testing device, to ensure reliable and stable electrical contact between the first conductive layer 4 and the outer surface of the insulating boot, and between the second conductive layer 5 and the inner surface of the insulating boot, a flexible conductive rubber material is selected as the main material for the conductive layers. This material possesses excellent softness, elasticity, and conductivity, and can automatically adapt to the microscopic undulations and deformations of the boot body during airbag inflation, thereby achieving large-area adhesion and current conduction.

[0063] Conductive rubber can be made from silicone rubber composites filled with silver powder, carbon black, or carbon nanotubes. Its thickness and hardness are optimized to maintain sufficient conductivity without applying excessive stress to the surface of the boot. Its material properties not only ensure stable conductivity but also have advantages such as pressure resistance, aging resistance, and corrosion resistance, making it suitable for long-term high-pressure testing conditions.

[0064] The introduction of this structure significantly improves the consistency and reliability of electrical contact during the testing process, avoiding testing errors or misjudgments caused by poor contact. It is particularly suitable for insulating boots with irregular surfaces, soft materials, or large size variations.

[0065] The formulation of the flexible conductive rubber material can be adjusted according to application requirements, such as improving flexibility for smaller boot sizes or enhancing compressive strength for heavy-duty testing scenarios. The conductive layer can also adopt a multi-layer composite structure, using highly conductive rubber in the inner layer and a wear-resistant protective film on the outer layer to extend service life. In addition, the conductive layer can be fixed to the surface of the airbag through various processes such as molding, heat bonding, adhesive bonding or overall wrapping to further improve the stability of its interface with the boot.

[0066] In one possible implementation, the control unit 9 is used to trigger the high-pressure detection system 6 to apply a high-pressure signal when the air pressure of the first airbag 2 and the second airbag 3 both reach the corresponding preset threshold.

[0067] To ensure the accuracy of insulation performance test results, this device sets trigger conditions through control unit 9: control unit 9 only activates high-voltage detection system 6 when the internal air pressure of the first airbag 2 and the second airbag 3 both reach their respective preset contact thresholds. This logical judgment process relies on the pressure sensors 8 respectively configured on the two airbags to collect and report the current air pressure status in real time.

[0068] The control unit 9 continuously compares the collected air pressure values ​​with internally stored standard thresholds. When both airbags are in a stable, fitted state, meaning the air pressure values ​​simultaneously meet or exceed the set standard, the judgment module issues a "start detection" command, which in turn triggers the high-voltage power supply to apply a predetermined voltage between the first conductive layer 4 and the second conductive layer 5. This logic avoids erroneous detection when the airbags are not fully fitted, eliminating risks such as poor contact and false judgments at the source.

[0069] This solution ensures that electrical signal testing is based on reliable mechanical contact, improving the repeatability and scientific rigor of the test results. The triggering mechanism can be set to automatic or a manual verification interface can be provided for operators to perform secondary confirmation based on interface prompts.

[0070] It is worth noting that the preset air pressure threshold can be adaptively adjusted by the system based on the model, material, or shape of the insulating boot; the judgment logic can also be optimized through training models to improve the trigger response speed and reliability; in a multi-station detection platform, this logic can be embedded in the local controller of each station to achieve distributed parallel detection.

[0071] In one possible implementation, the preset threshold is set according to the airbag structure parameters and the insulating boot shape parameters, respectively corresponding to the bonding state between the first conductive layer 4 and the outer surface of the insulating boot, and the bonding state between the second conductive layer 5 and the inner surface of the insulating boot.

[0072] To ensure sufficient contact between the conductive layer and the surface of the insulating boot before high-voltage testing, the preset air pressure threshold in the system is not fixed, but is set based on the structural dimensions (such as volume, wall thickness, and expansion elastic coefficient) of the first airbag 2 and the second airbag 3, as well as the morphological characteristics (such as size, cylinder rigidity, and inner cavity diameter) of the insulating boot being tested. After these parameters are initialized by the system or manually input by the user, the control unit 9 automatically matches a suitable target air pressure in conjunction with the preset calculation model.

[0073] For example, for a pair of insulated boots with a wide shaft and a stiff material, the air pressure threshold needs to be set slightly higher to ensure the outer airbag is fully covered; while the threshold for the inner airbag is set relatively moderately to ensure it does not rupture the inner lining of the boot. By modeling the fit and combining it with experimental data to form a corresponding relationship, the system can intelligently adjust the threshold to adapt to the needs of different boot types.

[0074] This method significantly improves the device's adaptability to various types of insulating boots, ensuring an ideal fit under different boot types, thus providing consistent and stable preconditions for subsequent insulation performance testing. It also avoids problems such as overly tight or insufficient fit caused by a one-size-fits-all fixed air pressure setting.

[0075] The preset threshold can be dynamically optimized based on historical detection data through machine learning algorithms; the system can also store multiple boot types and corresponding parameter templates for quick retrieval; if a 3D scanning or visual recognition unit is configured, it can also automatically identify the boot size and update the fitting threshold accordingly, achieving a high degree of automation and intelligence in the detection process.
