Description

Technical Field

[0001] This disclosure relates to the field of deep-sea high-pressure environment testing. More specifically, it relates to a simulation device, method, and testing system for simulating deep-sea high-pressure environments. Background Technology

[0003] The deep sea holds extremely rich strategic resources. In the deep-sea plains at depths of 4000-6000 meters, there are polymetallic nodules rich in manganese (approximately 25%), nickel (approximately 1.3%), cobalt (approximately 0.22%), and copper (approximately 1%), with total reserves reaching up to 3 trillion tons. The content of key metals such as nickel and cobalt far exceeds that of terrestrial mines, making them extremely valuable for mining. Cobalt, as a key element in high-temperature alloys, is widely used in aerospace, military, and other defense fields; while rare earth resources are the cornerstone of advancements in high-end electronic information equipment. Therefore, whether driven by the urgent needs of national defense and security or the development of strategic resources, the in-depth development of deep-sea engineering has become an inevitable trend.

[0004] The advancement of deep-sea engineering relies heavily on high-performance, highly reliable deep-sea engineering equipment. However, due to the unique operating environment of this equipment—facing extremely high hydrostatic pressure, high internal heat generated during operation, and the impact of high-voltage, high-frequency electrical signals—it is extremely difficult to verify the equipment in the actual deep-sea environment. Field tests are not only time-consuming and costly, but also limited by factors such as the difficulty of data acquisition and ecological interference, making it difficult to conduct rapid and effective performance evaluations during the research and development iteration of equipment and related components.

[0005] However, there is currently a lack of effective integrated testing methods for the performance verification of electronic components in deep-sea engineering equipment. This is not due to oversight in technology selection, but rather because integrating environmental simulation with electrical performance testing within the existing technological framework faces significant technical barriers. Specifically, conventional environmental simulation equipment, such as pressure tanks and temperature chambers, and electrical performance testing platforms are designed to serve drastically different operating conditions. The former focuses on pressure and temperature control in sealed containers, typically requiring only simple physical sensing circuitry; the latter focuses on precise electrical signal measurement, demanding extremely high standards for the dielectric properties of the test environment and the insulation and shielding of the circuitry. Simply placing the component under test in the liquid medium of a traditional pressure tank and attempting to apply high-voltage, high-frequency electrical signals through conventional lead holes will immediately trigger a series of serious problems such as dielectric breakdown, signal attenuation, and short circuits, rendering electrical performance testing impossible or producing distorted results. Therefore, these two types of testing have long been separate and operated independently. Summary of the Invention

[0006] The purpose of this disclosure is to provide a simulation device, method, and testing system for simulating and testing deep-sea high-pressure environments with high coupling in terms of pressure, temperature, and electrical performance, so as to solve at least one of the problems existing in the prior art.

[0007] To achieve the above objectives, the present disclosure adopts the following technical solution: The first aspect of this disclosure provides a simulation device for simulating a high-pressure environment in the deep sea, comprising: The simulator, controller, and multiple probes; The simulation chamber contains a test chamber filled with hydraulic oil. Multiple probes are inserted into the test chamber and sealed to the simulation chamber, and each probe is used to electrically connect to a device under test (DUT) in a deep-sea environment located within the test chamber; the probe is used to connect to a power supply to perform electrical performance testing on the DUT. The simulation chamber is equipped with a heater and a pressure control assembly; the test chamber is equipped with a pressure monitoring element for monitoring its pressure and a temperature monitoring element for monitoring its temperature. The controller is configured to acquire preset target pressure value, target temperature value, pressure holding time, and heat holding time; based on the pressure monitored by the pressure monitoring element, control the pressure control component to deliver hydraulic oil into the test chamber until the pressure in the test chamber reaches the target pressure value and is maintained for the pressure holding time; based on the temperature monitored by the temperature monitoring element, control the heater to heat the test chamber until the temperature in the test chamber reaches the target temperature value and is maintained for the heat holding time.

[0008] Optionally, the simulation chamber is sealed with a sealing cover; Multiple probes are inserted into the test chamber through the sealing cover.

[0009] Optionally, the heater includes a resistance heater.

[0010] Optionally, the pressure control assembly includes an oil storage tank and an oil pump, wherein the oil storage tank is connected to the test chamber via the oil pump; The controller is used to control the oil pump to deliver hydraulic oil into the test chamber until the pressure in the test chamber reaches the target pressure value and maintains the pressure for the specified time.

[0011] Optionally, the oil pump is a booster pump.

[0012] Optionally, the pressure monitoring element is a pressure sensor or a pressure transmitter; the temperature monitoring element is a temperature sensor or a temperature transmitter.

[0013] The second aspect of this disclosure provides a simulation method for simulating a deep-sea high-pressure environment applied to a simulation device as described in any one of the first aspects, the method comprising: The system acquires preset target pressure, target temperature, pressure holding time, and heat holding time; based on the pressure monitored by the pressure monitoring element, it controls the pressure control component to deliver hydraulic oil into the test chamber until the pressure in the test chamber reaches the target pressure and is maintained for the pressure holding time; based on the temperature monitored by the temperature monitoring element, it controls the heater to heat the test chamber until the temperature in the test chamber reaches the target temperature and is maintained for the heat holding time.

[0014] Optionally, the target pressure value ranges from 0.1 MPa to 17 MPa; the target temperature value ranges from 15°C to 150°C.

[0015] The third embodiment of the present invention provides a test system for simulating a high-pressure environment in the deep sea, including a power supply and a simulation device as described in the first embodiment; The power supply is used to output AC power with the preset target voltage value and preset target frequency to the corresponding components under test through multiple probes; and to output an alarm signal in response to the breakdown of all components under test.

[0016] Optionally, the preset target voltage value is less than or equal to 2000V, and the preset target frequency is 1kHz to 4kHz.

[0017] The beneficial effects of this disclosure are as follows: First, by using hydraulic oil as the pressure transmission medium and setting up multiple probes that are sealed and connected to the simulation chamber, this invention solves the problems of medium breakdown and circuit short circuit that are prone to occur when high-voltage high-frequency electrical signals are introduced in a high-pressure environment.

[0018] Secondly, the present invention can simultaneously apply deep-sea hydrostatic pressure, high-temperature environment and high-voltage high-frequency electrical stress to the component under test, thereby achieving high-fidelity simulation of the actual service environment of electronic components of deep-sea equipment and related applications.

[0019] Third, the controller of this invention can accurately set and maintain the target pressure value, temperature value, pressure holding time and heat holding time, making the test process highly repeatable.

[0020] Fourth, this invention can quickly complete the performance evaluation of deep-sea engineering equipment and its electronic components in a laboratory environment, without the need to frequently organize expensive and time-consuming deep-sea field trials, thereby significantly improving the R&D efficiency of deep-sea equipment.

[0021] Fifth, the system of this invention can monitor the status of the components under test (DUTs) in real time under high voltage, high temperature, and high frequency electrical signal impacts. When a DUT fails due to breakdown, it will be fed back through real-time current detection, and the data will be stored simultaneously. When all DUTs fail, the power supply system will cut off the voltage output and sound an alarm, ensuring safety. This makes the device not only an environmental simulation device, but also a comprehensive testing system integrating environmental simulation and electrical performance failure analysis. Attached Figure Description

[0022] The specific embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0023] Figure 1 This diagram shows a schematic of the structure of a simulation device for simulating a high-pressure environment in the deep sea. Detailed Implementation

[0024] To more clearly illustrate this disclosure, the following description, in conjunction with embodiments and accompanying drawings, provides further insight. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of this disclosure.

[0025] like Figure 1 As shown, the first embodiment of this disclosure provides a simulation device for simulating a high-pressure environment in the deep sea, comprising: The simulator 60, controller, and multiple probes 20; A test chamber 61 is formed inside the simulation chamber 60; the test chamber 61 is filled with hydraulic oil. Multiple probes 20 are inserted into the test chamber 61 and sealed to the simulation chamber 60, and each probe 20 is used to electrically connect to a test element 70 in a deep-sea environment disposed in the test chamber; the probe 20 is used to connect to the power supply 10 to perform electrical performance testing on the test element 70. The simulation chamber 60 is equipped with a heater 80 and a pressure control assembly; the test chamber 61 is equipped with a pressure monitoring element for monitoring its pressure and a temperature monitoring element for monitoring its temperature. The controller is configured to acquire preset target pressure value, target temperature value, pressure holding time, and heat holding time; based on the pressure monitored by the pressure monitoring element, control the pressure control component to deliver hydraulic oil into the test chamber 61 until the pressure in the test chamber 61 reaches the target pressure value and maintains the pressure holding time; based on the temperature monitored by the temperature monitoring element, control the heater 80 to heat the test chamber 61 until the temperature in the test chamber 61 reaches the target temperature value and maintains the heat holding time.

[0026] This invention solves the problems of medium breakdown and circuit short circuit that easily occur when high-voltage high-frequency electrical signals are introduced under high pressure environment by using hydraulic oil as the pressure transmission medium and setting up multiple probes 20 that are sealed and connected to the simulation chamber 60.

[0027] This invention can simultaneously apply deep-sea hydrostatic pressure, high-temperature environment, and high-voltage high-frequency electrical stress to the component under test, achieving high-fidelity reproduction of the actual service environment of electronic components in deep-sea equipment and related applications.

[0028] The controller of this invention can accurately set and maintain target pressure, temperature, pressure holding time, and temperature holding time, making the testing process highly repeatable.

[0029] This invention enables rapid performance evaluation of deep-sea engineering equipment and its electronic components in a laboratory environment, eliminating the need for frequent, expensive, and time-consuming field trials, thereby significantly improving the R&D efficiency of deep-sea equipment.

[0030] It should be noted that the deep-sea environment described in this embodiment specifically refers to the ocean space with a depth of less than 200 meters to tens of thousands of meters. This definition incorporates the standard in marine ecology based on light penetration capacity, i.e., the area below 200 meters is a light-free zone, and also incorporates the general classification standards in the field of marine engineering. The core characteristics of this environment are reflected in: First, the extremely high hydrostatic pressure. Seawater pressure increases linearly with depth, increasing by about one atmosphere for every 10 meters of depth; at a depth of 4,000 meters, the pressure can reach 40 MPa, while at a depth of 10,000 meters, it can even exceed 100 MPa.

[0031] Secondly, the complex thermal environment. It should be noted that the deep-sea environment simulated in this disclosure focuses on hydrostatic pressure and thermal field effects, without considering the chemical corrosion effects of seawater. This is because equipment and electronic components actually used in deep-sea applications typically employ sealed encapsulation structures, such as pressure-resistant hulls or potting treatments. This encapsulation layer effectively isolates the device under test 70 from external seawater, thereby avoiding direct electrochemical corrosion from seawater. Therefore, in the laboratory simulation environment, using insulating hydraulic oil as the pressure transmission medium can both reproduce the hydrostatic pressure conditions of deep seawater and conform to the electrical isolation state of the equipment during actual service. In this embodiment, the equipment and electronic components used in deep-sea applications are defined as the device under test 70.

[0032] Meanwhile, while existing encapsulation structures can isolate the device from seawater, they also significantly weaken the device's ability to exchange heat with the external seawater. In the deep-sea environment, although the external seawater temperature is low, the high thermal resistance of the encapsulation layer makes it difficult to dissipate the heat generated during device operation in a timely manner, leading to heat accumulation inside and causing internal temperature rise. Especially when the device is operating at high power, the internal temperature can reach over 50°C, posing a challenge to electronic components for long-term high-temperature service. Therefore, this device simulates deep-sea pressure while also precisely controlling the temperature field to reproduce the internal thermal environment characteristics of the device under encapsulation conditions.

[0033] Meanwhile, to ensure stable operation of the equipment under high pressure and high temperature environments, especially for deep-sea exploration equipment that requires high voltage signal output, such as common marine electromagnetic transmitters or electric spark sources, whose operating voltage is often in the range of 1~3kV, the electronic components used must have high withstand voltage strength. In summary, the device under test 70 in this disclosure operates in a high temperature, high pressure and high voltage environment.

[0034] In a specific example, an anti-wear hydraulic oil is selected. The difference between anti-wear hydraulic oil and seawater is that seawater is an excellent conductor of electricity. Seawater contains a large amount of salt, which dissolves in water and decomposes into positively charged sodium ions and negatively charged chloride ions. When a voltage is applied, these ions move in a directed manner to form an electric current. Hydraulic oil, on the other hand, is an insulator. Whether it is hydraulic oil or a further-specific anti-wear hydraulic oil, its main component is base oil, which has a stable molecular structure and contains almost no freely moving charged particles, therefore it is non-conductive.

[0035] In a specific example, the probe 20 employs a coaxial multilayer insulation structure. Specifically, each probe 20 has a conductive core rod at its center for transmitting high-voltage, high-frequency electrical signals to the device under test 70. The core rod is sequentially covered with a high-temperature and high-pressure resistant insulation layer and a metal shielding layer. The insulation layer is preferably made of polyetheretherketone (PEEK) or ceramic material to prevent interference from the high-voltage electric field to the surrounding environment and adjacent probes. The outermost layer of the probe 20 is provided with a sealing seat that is mechanically connected to the simulation chamber 60 or the sealing cover 30. The sealing seat and the chamber are sealed using a radial or end-face sealing structure, such as an O-ring or a metal gasket, to ensure no hydraulic oil leakage under a maximum pressure of 17 MPa. The tail of the probe 20 is connected to the power supply 10 via a high-voltage connector or terminal block, while its head extends into the test chamber 61. A special clamp or adapter can be provided depending on the interface type of the device under test 70. To further improve insulation reliability, a skirt structure can be provided in the area where the probe 20 is inserted into the test chamber 61 to increase the creepage distance.

[0036] In another specific embodiment, the probe 20 employs a standardized high-voltage electrical connector, such as an underwater pluggable connector. This connector is internally filled with an insulating medium and undergoes rigorous withstand voltage testing, with a rated operating voltage of no less than 4kV and an insulation resistance greater than 200MΩ. The probe 20 and the sealing cover 30 are connected by threads and secured with a sealing ring to ensure a good seal even after repeated disassembly and reassembly.

[0037] In another specific embodiment, the probe 20 can be customized as a multi-core structure, that is, multiple independent conductive channels are integrated within a single probe assembly, with each channel isolated by an insulating layer. This structure can be used to simultaneously transmit multiple electrical signals to the same device under test 70, or to provide independent electrical connections for multiple devices under test 70, thereby simplifying the number of openings on the sealing cover 30 and improving the overall structural strength and sealing reliability of the simulation chamber 60.

[0038] In another specific embodiment, the connection end between the probe 20 and the element under test 70 is provided with an elastic contact probe or spring pin to adapt to minute displacements caused by temperature changes or pressure fluctuations, ensuring long-term stability of the electrical contact. Meanwhile, the outer shell material of the probe 20 is preferably stainless steel or titanium alloy to balance corrosion resistance, mechanical strength, and coefficient of thermal expansion; the internal insulating components are made of polymer materials with low hygroscopicity and high volume resistivity.

[0039] In one specific example, the probe 20 and the power supply 10 are connected by a cable, which is a high-voltage resistant cable configured with a withstand voltage rating of 2kV-4kV. To meet the requirements, a high-voltage probe with a withstand voltage of 10MPa-70MPa is selected. Furthermore, testing has verified that the probe can operate stably for a long period at 10MPa, 70℃, 4kHz, and a peak voltage of 2kV.

[0040] It should be noted that the above-described probe 20 structure is merely an example of the present invention, and the present invention does not limit the specific structure of the probe 20.

[0041] In one possible implementation, a sealing cover 30 is provided on the simulation chamber 60; multiple probes 20 are respectively inserted into the test chamber 61 through the sealing cover 30. The present invention provides an independent sealing cover 30 on the simulation chamber 60 and centrally places multiple probes 20 through the sealing cover 30, which facilitates the setting of probes 20 and the device under test 70, and also facilitates maintenance.

[0042] In one possible implementation, the heater 80 includes a resistance heater 80. A resistance heater 80 is a device that generates heat energy using the thermal effect of electric current. Currently, existing analog equipment generally uses water bath heating. However, in this embodiment, the analog equipment needs to apply high-frequency alternating current to electronic components under high pressure. The hydraulic oil filling the test chamber 61 is itself designed to ensure electrical insulation performance. If water bath heating is used, it means that a water jacket or water tank needs to be installed outside the chamber. If the seal fails or condensation occurs, water may seep into the test chamber 61 or contact the probe 20. Water is conductive and will damage the insulation environment, leading to test signal leakage and measurement distortion, or even short circuits or equipment damage.

[0043] This simulation device uses a resistance heater 80 to heat the hydraulic oil. It has excellent electrical compatibility. Resistance heating is a purely resistive load. During operation, it only generates a thermal field without introducing alternating electromagnetic interference, ensuring that the high-frequency AC signal applied by the power supply 10 to the device under test 70 through the probe 20 is pure and stable. The resistance heater 80 can be directly attached to the bulkhead. It has a short heat transfer path and low thermal inertia. When combined with temperature monitoring elements, it can achieve high-precision closed-loop temperature control.

[0044] In this embodiment, multiple resistance heaters 80 can be used. In addition, tubular, plate or ring-shaped forms can be selected according to the structure of the simulation chamber 60 and the heating requirements.

[0045] In a specific example, the heater 80 in this embodiment is a tubular heater 80, which can be bent into a U-shape or a spiral shape to facilitate immersion heating by extending into the test chamber 61 from the sealing cover 30. It has good heating uniformity and is suitable for applications where hydraulic oil is directly heated. Using a tubular heater 80 to extend into the chamber through the sealing cover 30 for immersion heating can achieve a faster heating rate and a more uniform temperature field distribution.

[0046] In another example, there are multiple heaters 80, which are evenly attached to the outer wall of the simulation chamber 60.

[0047] In one possible implementation, the pressure control assembly includes an oil storage tank 100 and an oil pump 90, the oil storage tank 100 being connected to the test chamber 61 via the oil pump 90; The controller is used to control the oil pump 90 to deliver hydraulic oil into the test chamber 61 to regulate the pressure in the test chamber 61 until the pressure in the test chamber 61 reaches the target pressure value and is maintained for the specified holding time. This invention uses a pressure control component consisting of an oil storage tank 100 and an oil pump 90. The controller regulates the pressure in the test chamber 61 through a closed-loop control. In this embodiment, the oil pump 90 has a fast response speed and can accurately control the delivery volume of hydraulic oil based on real-time feedback from the pressure monitoring element, allowing the pressure in the test chamber 61 to rise steadily to the preset target value. During the holding period, it dynamically compensates for pressure fluctuations caused by temperature changes or minor leaks, ensuring that the pressure stability meets the test requirements.

[0048] In a specific example, the oil storage tank 100 includes a tank body, the interior of which is divided into a sedimentation zone, a filtration zone, and a degassing zone connected in sequence. The sedimentation zone has an inclined bottom and a drain outlet for settling and discharging large particulate impurities; the filtration zone has a filter screen and magnetic adsorption elements for intercepting small particles and metal shavings; the degassing zone has an exhaust valve at the top for releasing air bubbles in the oil. After sedimentation, filtration, and degassing, the oil is supplied to the oil pump 90 through the outlet of the oil storage tank 100. By performing sedimentation, filtration, and degassing treatment on the hydraulic oil in the oil storage tank 100, impurities or air bubbles are prevented from entering the test chamber 61. Air bubbles are prone to causing partial discharge under high voltage, and impurities may wear down the oil pump 90 or contaminate the component under test 70. This invention, through the pretreatment function of the oil storage tank 100, ensures the purity of the test environment and the reliability of equipment operation from the source.

[0049] In one possible implementation, the oil pump 90 is a booster pump. In a specific example, a booster pump is a fluid transport device used to increase the pressure of a liquid and deliver it to a high-pressure system. Its working principle is to apply mechanical energy to the liquid through mechanical motion, increasing the liquid's pressure energy to overcome system resistance or reach a preset pressure value.

[0050] In one possible implementation, the pressure monitoring element is a pressure sensor or a pressure transmitter; the temperature monitoring element is a temperature sensor or a temperature transmitter.

[0051] The second embodiment of this disclosure provides a simulation method for simulating a deep-sea high-pressure environment using a simulation device as described in any one of the first embodiments. The method is applied to a controller and includes: The system acquires preset target pressure, target temperature, pressure holding time, and heat holding time; based on the pressure monitored by the pressure monitoring element, it controls the pressure control component to deliver hydraulic oil into the test chamber 61 until the pressure in the test chamber reaches the target pressure and is maintained for the pressure holding time; based on the temperature monitored by the temperature monitoring element, it controls the heater 80 to heat the test chamber 61 until the temperature in the test chamber 61 reaches the target temperature and is maintained for the heat holding time.

[0052] In a specific example, the simulation method includes the following steps: The component under test 70 is clamped onto a special fixture, specifically, the other end of the fixture is connected to the probe 20 to receive electrical signals. The device is equipped with a total of 8 probes 20, which can test up to 8 samples at a time. After the samples are fixed, the sealing cover 30 is lowered onto the simulation chamber 60 via an auxiliary lead screw, and the fixing bolts 40 are tightened to complete the sealing of the test chamber 61.

[0053] The controller inputs preset target pressure, target temperature, pressure holding time, and temperature holding time onto the operation panel. Based on the real-time pressure monitoring of the pressure monitoring element, the controller controls the oil pump 90 to deliver hydraulic oil from the oil storage tank 100 to the test chamber 61, causing the pressure to rise steadily to the target pressure value and maintain the set pressure holding time. Simultaneously, based on the real-time temperature monitoring of the temperature monitoring element, the controller controls the heating element to heat the test chamber 61, causing the temperature to rise to the target temperature value and maintain the set temperature holding time. Once both pressure and temperature reach the preset conditions, the power supply 10 outputs AC power with preset target voltage and preset target frequency to the corresponding test element 70 through multiple probes 20.

[0054] During the test, the holding time can be set via the controller, with a maximum setting of 8 hours. During this holding time, the controller continuously maintains the pressure and temperature in the test chamber 61 at the target pressure and temperature values ​​based on feedback from the pressure and temperature monitoring elements until the holding time ends. For long-term tests (≥8 hours), there is no need to set the holding time or temperature holding time; the target parameters are maintained continuously during the test, and the equipment can be shut down after the test.

[0055] During the test, pressure and temperature data within the chamber are collected in real time using pressure and temperature transmitters and displayed on a touch panel. After the test, the pressure and temperature data curves over time for the test period can be exported to a USB drive for subsequent analysis.

[0056] After the test is completed, turn off the heating and pressurization program via the controller, and then turn off the external high-voltage power supply. After the pressure inside the chamber has been released to a safe value, loosen the fixing bolt 40, lift the sealing cover 30 via the screw, and remove the test sample.

[0057] In one specific example, an auxiliary lead screw 50 for limiting the installation of the sealing cover 30 is inserted between the sealing cover 30 and the simulation chamber 60. The auxiliary lead screw 50 is fixed to the simulation chamber 60.

[0058] In one specific example, the alarm signal includes the probe channel identification information where a breakdown has occurred; the controller determines the faulty component under test 70 based on the channel identification information.

[0059] In one possible implementation, the target pressure value ranges from 0.1 MPa to 17 MPa. Preferably, it is from 9 MPa to 15 MPa.

[0060] In one possible implementation, the target temperature value ranges from 15°C to 150°C. Preferably, it is from 50°C to 100°C.

[0061] In one possible implementation, the preset target voltage value is less than or equal to 2000V, and the preset target frequency is in the range of 1kHz to 4kHz.

[0062] In a specific example, the present invention was verified through testing. The test equipment operated for 48 hours under conditions of 10 MPa pressure, 70°C temperature, 4 kHz frequency, and 4 kV AC power without exhibiting any abnormalities. It can operate stably for 48 hours. Furthermore, testing showed that this environment can meet the stability testing requirements of most components.

[0063] In one possible implementation, the third embodiment of the present invention provides a test system for simulating a deep-sea high-pressure environment, including a power supply and a simulation device as described in any one of the first embodiments; The power supply is used to output AC power with the preset target voltage value and preset target frequency to the corresponding components under test through multiple probes; and to output an alarm signal in response to the breakdown of all components under test.

[0064] The system of this invention can monitor the status of the components under test (DUTs) in real time under high voltage, high temperature, and high frequency electrical signal impacts. When a DUT fails due to breakdown, the failure will be detected and reported in real time via current detection, and the data will be stored. When all DUTs fail, the power supply system will cut off the voltage output and sound an alarm to ensure safety. This makes the device not only an environmental simulation device, but also a comprehensive testing system integrating environmental simulation and electrical performance failure analysis.

[0065] In one specific embodiment, eight probes 20 are connected in parallel to the power supply 10 via a high-voltage junction box. During testing, an external power supply is used as the power supply 10, and an oscilloscope is used as a current and voltage monitoring device to monitor the total current and voltage changes in the circuit in real time, so as to ensure that the voltage applied to each component under test is consistent with the preset value.

[0066] In a single test scenario for a component under test, if a breakdown occurs and an internal circuit is formed, the power supply system will immediately trigger an alarm and cut off the voltage input.

[0067] Similarly, when multiple components under test are tested in parallel, the failure process and monitoring logic are as follows: When high-voltage AC current is applied to each parallel-connected component under test (DUT), the oscilloscope acquires and records the total current value of the circuit in real time. Because the components are connected in parallel, when one component breaks down and short-circuits, a complete short-circuit path is not formed due to the presence of other normal components in the circuit. At this point, the current change is used to determine the breakdown failure of a particular DUT. The detection system records the current abnormal current value and the corresponding timestamp in local storage. As subsequent components break down one by one, when the last DUT breaks down, the total circuit impedance approaches zero. When power is applied again for detection, the total current instantly surges to the short-circuit current, triggering the overcurrent alarm threshold of the external power supply, and the controller immediately outputs an alarm signal.

[0068] In one possible implementation, the preset target voltage value is less than or equal to 2000V, and the preset target frequency is in the range of 1kHz to 4kHz.
