Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of controllable nuclear fusion, and in particular to a hydrogen thyratron intelligent heating control method, device, equipment and storage medium. BACKGROUND

[0002] As a gas switch with strong through-flow capacity, high working voltage and fast opening speed, the hydrogen thyratron is widely used in the field of high-voltage pulse power. When the hydrogen thyratron works, a heating voltage needs to be applied on a heating power source for a period of time to raise the temperature of the hydrogen storage chamber inside the hydrogen thyratron, so that the hydrogen storage device releases hydrogen, thereby increasing the gas pressure in the hydrogen thyratron. After the gas pressure in the hydrogen thyratron is raised, a lower trigger voltage applied on the trigger electrode can turn the hydrogen thyratron from an insulating state to a conducting state. When the current flowing through the hydrogen thyratron cannot maintain the plasma discharge, the hydrogen thyratron is automatically turned off.

[0003] In the conduction process of the hydrogen thyratron, the heating voltage plays a very key role. If the heating voltage is too low, the gas inside the hydrogen thyratron cannot be heated sufficiently, and even if a correct trigger pulse is applied, the hydrogen thyratron cannot be turned on. On the contrary, if the heating voltage is too high, the gas inside the hydrogen thyratron is overheated, and the hydrogen thyratron may be turned on in advance due to self-flashing before the trigger pulse arrives. Whether the heating voltage is too low or too high, the reliability of the hydrogen thyratron in normal conduction according to the timing sequence is affected.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0021] In order to facilitate the understanding of the technical solutions of the present application, the technical problems to be solved by the present application will be described first.

[0022] Hydrogen thyratron is a commonly used gas switch in the field of high-voltage pulse power, which has the advantages of strong current-carrying capacity, high working voltage, and fast turn-on speed. By first applying a heating voltage to the heating power supply, the internal hydrogen storage chamber is heated to release hydrogen, and the gas pressure in the tube is raised. Then, a low trigger voltage is triggered to conduct. When the current cannot maintain plasma discharge, it will automatically shut off.

[0023] In the conduction of hydrogen thyratron, too low heating voltage will result in insufficient heating of the gas, and the correct trigger pulse cannot be applied to conduct. Too high heating voltage will cause the gas to overheat, which may lead to early conduction before the trigger pulse arrives. Both of them affect the reliability of the normal conduction according to the timing. Therefore, the heating voltage needs to be precisely controlled.

[0024] Current hydrogen thyratron heating control mainly relies on manual open-loop adjustment or simple mechanical control, which has the problems of low adjustment precision and slow response speed, and it is difficult to meet the demand for accurate and efficient control. Therefore, how to realize high-precision control of hydrogen thyratron heating has become a technical problem to be solved.

[0025] To solve the above problems, the application provides a hydrogen thyratron intelligent heating control method, which obtains real-time temperature data of the hydrogen thyratron, converts the real-time temperature into voltage analog quantity, further converts the voltage analog quantity into current analog quantity, and finally generates a control signal according to the current analog quantity to control the heating voltage of the heating power supply of the hydrogen thyratron, so as to realize closed-loop control of the hydrogen thyratron and keep the hydrogen thyratron at the optimal working temperature. Not only can the heating voltage of the heating power supply of the hydrogen thyratron be adjusted by avoiding relying on manual open-loop adjustment or simple mechanical control, but also the real-time temperature of the hydrogen thyratron can be converted into current analog quantity, and the heating voltage of the heating power supply can be controlled based on the current analog quantity, so that the temperature adjustment precision and response speed of the hydrogen thyratron can be greatly improved.

[0026] The hydrogen thyratron intelligent heating control method of the embodiment of the application will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 , Figure 1 The hydrogen thyratron intelligent heating control method of the embodiment of the application will be described in detail below with reference to the accompanying drawings. Figure 2 The hydrogen thyratron intelligent heating control system model diagram of the embodiment of the application is shown.

[0028] As Figure 1 shown, the method steps include S110-S140.

[0029] S110, real-time temperature data of the hydrogen thyratron is obtained, and the real-time temperature data is converted into representative temperature voltage data of the hydrogen thyratron. The step corresponds to step a in Figure 2 .

[0030] As Figure 2 shown, in the implementation process of the application, in step a, the real-time temperature data of the hydrogen thyratron is converted into representative temperature voltage data of the hydrogen thyratron by a temperature-voltage conversion unit, and the step S110 will be described in detail below.

[0031] It can be understood that the temperature signal is converted into the voltage signal to adapt the processing logic of the electronic control system. By converting the real-time temperature data of the hydrogen thyratron into representative temperature voltage data, the change response of the hydrogen thyratron temperature is converted into the change response of the hydrogen thyratron voltage.

[0032] In the embodiment of the application, the real-time temperature data is converted into representative temperature voltage data of the hydrogen thyratron by a resistance voltage dividing circuit.

[0033] It can be understood that the resistance voltage dividing circuit indirectly converts the resistance value change of the thermistor into the representative temperature voltage data of the hydrogen thyratron by using the resistance value change characteristic of the temperature sensitive resistance with temperature, by Ohm's law and the voltage dividing principle.

[0034] By accurate design of the resistance voltage dividing circuit parameters and in combination with the clear conversion formula, the linearity and accuracy of the temperature-voltage mapping are ensured, and reliable original data is provided for subsequent control.

[0035] Since the resistance voltage dividing circuit only needs to connect the fixed resistance and the thermistor in series to obtain the voltage dividing resistance, and then connect the voltage dividing resistance with the input power supply, the real-time temperature data of the hydrogen thyratron is measured by the thermistor, and the representative temperature voltage data of the hydrogen thyratron is obtained by measuring the voltage at the output end of the voltage dividing resistance. The advantage is that the resistance voltage dividing circuit has a simple structure, low cost, no additional heating interference, and will not cause distortion of the measured real-time temperature data.

[0036] In some embodiments, the real-time temperature data can be converted into the representative temperature voltage data of the hydrogen thyratron by the combination of the thermal resistance and the bridge.

[0037] It can be understood that the combination of the thermal resistance and the bridge is to tightly attach a thermistor to the hydrogen thyratron for measuring the real-time temperature data of the hydrogen thyratron, and the above thermistor and another three fixed resistors are respectively used as the resistance arms of the bridge, and then one diagonal of the bridge is connected with a direct current power supply and the other diagonal is used as an output end, so that the representative temperature voltage data of the hydrogen thyratron is obtained by measuring the voltage at the output end. Since the bridge can offset the influence of power supply fluctuation and wire resistance, the error of the measured real-time temperature data of the hydrogen thyratron is small. The resistance value of the thermal resistance itself has a linear relationship with temperature, and the output voltage of the bridge also changes linearly with temperature, so that subsequent calculation does not need complex calibration, and data processing is simpler.

[0038] In the embodiments of the present application, the calculation formula of the resistance voltage dividing circuit is:

[0039] wherein, V out （t） Vt is the representative temperature voltage data of the hydrogen thyratron at time t, V ref Vref is the reference power supply voltage data of the voltage dividing circuit, R f Rf is the fixed current limiting resistance of the voltage dividing circuit, R 0 R0 is the nominal resistance value of the temperature detection element at 0 degrees, α K is the resistance temperature coefficient of the temperature detection element, T(t) T is the actual temperature of the hydrogen thyratron at time t,t This is a time parameter.

[0040] In some embodiments, the temperature-sensitive resistor in the resistive voltage divider circuit is a PT100 resistor or an NTC resistor, etc.

[0041] It is understandable that the temperature changes of the hydrogen thyratron can be captured in real time by directly contacting the temperature-sensitive resistor on the surface of the hydrogen thyratron.

[0042] S120, based on representative temperature and voltage data, obtains the analog voltage quantity used in the voltage regulation stage. This step is related to... Figure 2 This corresponds to step b in the middle.

[0043] like Figure 2 As shown, in the implementation process of this invention, in step b, the representative temperature and voltage data output by the temperature-to-voltage conversion unit, and the voltage value corresponding to the optimal operating temperature of the hydrogen thyratron (i.e., V) are used. set-temp The difference between the two is calculated, and then the difference is input to the proportional-integral controller, which processes the voltage analog quantity to obtain the voltage analog quantity.

[0044] Understandably, converting the voltage signal related to the temperature of the hydrogen thyratron into a quantized command that can be directly used for voltage regulation builds a bridge between temperature feedback and voltage control, ensuring that the voltage regulation process can accurately respond to temperature changes.

[0045] S130 converts the analog voltage signal into a first analog current signal for use in the current regulation circuit. Step S130 is related to... Figure 2 This corresponds to step c in the middle.

[0046] like Figure 2 As shown, in the implementation process of this invention, in step c, the real-time voltage data of the hydrogen thyratron is obtained through a voltage sensor, and the initial value of the heating voltage of the hydrogen thyratron (i.e., V) is obtained. set-heat ), and based on the analog voltage and the initial value of the heating voltage (i.e., V). set-heat The second voltage difference is obtained by combining the real-time voltage data with the input of the second proportional-integral controller to obtain the first analog current.

[0047] It is understandable that converting voltage commands into current commands can improve the current drive characteristics of the heating power supply adapted to the hydrogen thyratron, making the control commands closer to the needs of the execution end, while improving the response speed of the heating power supply of the hydrogen thyratron.

[0048] S140: Based on the first analog current, a control signal is generated to adjust the heating voltage of the heating power supply for the hydrogen thyratron. The magnitude of the heating voltage is controlled based on this control signal to ensure the hydrogen thyratron is always at its optimal operating temperature. This step is related to... Figure 2This corresponds to step d in the middle section.

[0049] like Figure 2 As shown, in the implementation process of this invention, in step d, the real-time current data of the hydrogen thyratron is obtained by a current sensor. Based on the analog current and the real-time current data, the current difference between the two is calculated. The current difference is then used as the input of the current PI controller to obtain the second analog current. Finally, the second analog current is used as the input of the PWM controller to obtain the control signal for adjusting the heating voltage of the heating power supply of the hydrogen thyratron.

[0050] Understandably, the first analog current quantity serves as a crucial bridge connecting the voltage regulation requirements with the final heating voltage control. It visualizes the voltage regulation required for temperature stabilization as an executable current regulation parameter, and is a key intermediate instruction for achieving closed-loop temperature control, ensuring the effective transmission of regulation logic from the temperature target to the actual heating control.

[0051] Below, on Figure 1 Steps S120-S140 are further explained in detail.

[0052] refer to Figure 3 , Figure 3 A flowchart of step S120 of an embodiment of the present invention is shown, wherein step S120 includes: S121, obtain the voltage value corresponding to the optimal operating temperature of the hydrogen thyratron.

[0053] S122, based on the voltage value corresponding to the optimal operating temperature and the voltage data of the representative temperature, obtain the first voltage difference.

[0054] S123, based on the first voltage difference, obtain the analog voltage quantity.

[0055] In an embodiment of the present invention, the first voltage difference is obtained by subtracting the voltage data representing the temperature from the voltage value corresponding to the optimal operating temperature. The first voltage difference is then used as the input of the first proportional-integral controller to obtain the analog voltage quantity.

[0056] In an embodiment of the present invention, the formula for calculating the analog voltage is as follows:

[0057] in, V cl （t） Let be the analog voltage at time t. K p This refers to the proportional coefficient in the first proportional-integral controller. K i The integral coefficient in the first proportional-integral controller. V set-tempthe voltage value corresponding to the optimal working temperature, t the time parameter, x the time integral variable, V out (t) is the representative temperature voltage data of the hydrogen thyratron at the moment t, is the representative temperature voltage data of the hydrogen thyratron at the moment x.

[0058] It can be understood that the closed-loop logic of temperature feedback-voltage regulation is first constructed, which breaks through the limitation that the traditional open-loop control cannot correct the deviation, and ensures that the temperature of the hydrogen thyratron converges to the optimal value; the integral action of the first proportional-integral controller (PI controller) can completely eliminate the temperature deviation, and solve the problem that the temperature is stabilized at a non-optimal value in the traditional control; the proportional action can quickly respond to the temperature fluctuation, shorten the adjustment time, and improve the adaptability of the system to dynamic changes.

[0059] In the embodiment of the present application, when the voltage analog quantity is higher than the preset highest voltage value or lower than the preset lowest voltage, the hydrogen thyratron control system corrects the voltage analog quantity through the anti-windup integral algorithm, so that the voltage analog quantity is kept between the highest voltage value and the lowest voltage value, thereby preventing the voltage analog quantity from being too high to cause the output voltage of the heating power supply of the hydrogen thyratron controlled by the finally generated control signal to be too high, so that the working temperature of the hydrogen thyratron is too high and the hydrogen thyratron is damaged, and preventing the voltage analog quantity from being too low to cause the output voltage of the heating power supply of the hydrogen thyratron controlled by the finally generated control signal to be too low, so that the working temperature of the hydrogen thyratron is too low and the hydrogen thyratron cannot be turned on, thereby improving the reliability and safety of the system. By setting the anti-windup integral algorithm, it is ensured that the hydrogen thyratron control system can maintain rapid and non-delayed dynamic response performance in the limiting amplitude state.

[0060] Reference Figure 4 , Figure 4 A flowchart of step S130 of the embodiment of the present application is shown, wherein step S130 comprises: S131, obtaining the initial heating voltage value of the hydrogen thyratron and the real-time voltage data of the hydrogen thyratron.

[0061] In the embodiment of the present application, the real-time voltage data of the hydrogen thyratron can be obtained through a voltage sensor.

[0062] S132, obtaining the second voltage difference value based on the voltage analog quantity, the initial heating voltage value and the real-time voltage data.

[0063] In the embodiment of the present application, the voltage analog quantity is added to the initial heating voltage value to obtain an accumulated voltage value, and then the accumulated voltage is subtracted from the real-time voltage data to obtain the second voltage difference value.

[0064] It can be understood that the dynamic target voltage reference (accumulated voltage value) is generated by accumulating the voltage analog quantity to the heating voltage initial value, and then compared with the real-time voltage data to obtain the second voltage difference value, which is essentially to construct the deviation quantitative index of the dynamic target value and the actual value, and to provide accurate deviation basis for subsequent current regulation.

[0065] In the embodiment of the present application, the second voltage difference value is taken as the input of the second proportional-integral controller to obtain the first current analog quantity.

[0066] In the embodiment of the present application, the second voltage difference value is taken as the input of the second proportional-integral controller to obtain the first current analog quantity.

[0067] It can be understood that the first current analog quantity is generated by taking the second voltage difference value as the input through the second proportional-integral (PI) controller, which essentially converts the voltage deviation into current regulation instruction to realize the link transmission from voltage control to current control. The PI controller quickly responds to the voltage deviation through the proportional element (the greater the deviation, the stronger the current regulation instruction), and eliminates the static deviation through the integral element (to avoid long-term deviation of the voltage from the target value), and finally the output current analog quantity directly guides the subsequent current regulation.

[0068] In the embodiment of the present application, the calculation formula of the first current analog quantity is:

[0069] Wherein, I cl （t） is the first current analog quantity at t moment, K p2 is the proportional coefficient in the second proportional-integral controller, V set-heat is the heating voltage initial value, V real （t） is the real-time voltage data at t moment, K i2 is the integral coefficient in the second proportional-integral controller, t is a time parameter, x is a time integral variable, V cl （x） is the voltage analog quantity at x moment, V real （x） is the real-time voltage data at x moment.

[0070] It can be understood that the voltage-current secondary closed loop is added on the basis of temperature-voltage closed loop to realize the control from temperature control to voltage control and then to current control, and further to refine the control granularity of the control system to the heating power supply of the hydrogen thyratron.

[0071] Reference Figure 5 , Figure 5 A flow chart of step S140 of the embodiment of the application is shown, wherein step S140 comprises: S141, obtaining real-time current data of the hydrogen thyratron.

[0072] S142, obtaining a current difference value based on the first current analog quantity and the real-time current data.

[0073] In the embodiment of the application, the current difference value is obtained by subtracting the real-time current data from the current analog quantity.

[0074] It can be understood that the current difference value directly reflects the gap between the current actual current and the target current (for example, if the difference value is positive, it means that the actual current is lower than the target; if the difference value is negative, it means that the actual current is higher than the target). This quantitative result is the original signal for subsequent accurate current regulation, which ensures that the regulation direction (increasing / decreasing current) and amplitude have clear data support.

[0075] S143, obtaining a second current analog quantity based on the current difference value.

[0076] In the embodiment of the application, the current difference value is taken as the input of the third proportional-integral controller to obtain the second current analog quantity.

[0077] In the embodiment of the application, the calculation formula of the second current analog quantity is:

[0078] wherein, I out (t) is the second current analog quantity at time t, K p3 is the proportional coefficient of the third proportional-integral controller, I cl (t) is the first current analog quantity at the above-mentioned time t, I real (t) is the real-time current data at time t, K i3 is the integral coefficient of the third proportional-integral controller, t is a time parameter, x is a time integral variable, I cl (x) is the first current analog quantity at time x, I real (x) is the real-time current data at time x.

[0079] It can be understood that the third proportional-integral (PI) controller takes the current difference value as the input, quickly responds to the deviation through the proportional element, eliminates the static deviation through the integral element, and finally outputs the second current analog quantity. This process is essentially a dynamic correction and optimization of the current deviation, which converts the original deviation signal into a smoother and more accurate current regulation instruction, laying a foundation for the generation of the final control signal.

[0080] In the embodiments of the present application, when the second current analog quantity is higher than the preset maximum current value or lower than the preset minimum current value, the hydrogen thyratron control system corrects the second current analog quantity by the anti-saturation integral algorithm, so that the second current analog quantity is kept between the maximum current value and the minimum current value, thereby preventing the second current analog quantity from being too high, which causes the output voltage of the heating power supply of the hydrogen thyratron controlled by the finally generated control signal to be too high, and the working temperature of the hydrogen thyratron to be too high, resulting in damage to the hydrogen thyratron, and preventing the second current analog quantity from being too low, which causes the output voltage of the heating power supply of the hydrogen thyratron controlled by the finally generated control signal to be too low, and the working temperature of the hydrogen thyratron to be too low, resulting in that the hydrogen thyratron cannot be turned on, thereby improving the reliability and safety of the system. By providing the anti-saturation integral algorithm, it is ensured that the hydrogen thyratron control system can maintain fast and non-delayed dynamic response performance in the limiting amplitude state.

[0081] S144, generating a control signal based on the second current analog quantity.

[0082] In the embodiments of the present application, the second current analog quantity is taken as the input of the pulse width modulation controller to obtain the control signal.

[0083] It should be noted that the control signal can include a duty cycle adjustment instruction. The duty cycle adjustment instruction can include an instruction to increase the duty cycle if the second current analog quantity indicates that the actual current is less than the target current. For example, the original duty cycle of the PWM pulse is 30% (i.e., the high level time accounts for 30% in one period), and now it is adjusted to 50%. This will prolong the conduction time of the heating power supply of the hydrogen thyratron, more electric energy can be transferred to the related circuit, and finally the working temperature of the hydrogen thyratron is improved, so that the hydrogen thyratron is always in the best working temperature state.

[0084] It can be understood that after the pulse width modulation (PWM) controller receives the second current analog quantity, it is converted into a pulse control signal with a specific duty cycle. The size of the duty cycle directly corresponds to the current regulation demand (for example, increasing the duty cycle can prolong the conduction time of the hydrogen thyratron and increase the actual current; reducing the duty cycle can shorten the conduction time and reduce the actual current). The control signal can directly act on the heating power supply of the hydrogen thyratron, and by adjusting the working time or power, the actual current can be finally stabilized in the target range, completing the closed loop from deviation detection to physical control.

[0085] In some embodiments, the second current analog quantity can be taken as the input of the programmable logic controller to obtain the control signal.

[0086] It can be understood that compared with the programmable logic controller, the pulse width modulation controller has the advantages of higher efficiency, higher control precision, stronger anti-interference ability, more stable signal transmission, etc.

[0087] It can be understood that a three-level closed-loop system of temperature-voltage-current-execution signal is constructed, and feedback correction is introduced at each link from perception to execution, so that the problems of low precision and slow response of traditional open-loop control are completely solved; the PWM controller can realize stepless adjustment of the output of the heating power supply through the linear correlation of duty ratio and output current data, and the precision is much higher than that of mechanical switch or step adjustment; the third proportional-integral controller performs final correction for current deviation, can compensate for end disturbances such as load changes and sensor errors, and ensures that the final heating current is stable at the target value; through full-link closed-loop control, the hydrogen thyratron temperature is finally stabilized at the optimal working temperature, avoiding the problems of insufficient heating and self-flashing due to overheating, and significantly improving the reliability of the hydrogen thyratron in terms of timing conduction.

[0088] In the embodiment of the present application, before controlling the size of the heating voltage of the heating power supply of the hydrogen thyratron based on the control signal, the control signal is further subjected to filtering processing. Wherein, the step corresponds to e in Figure 2 .

[0089] As shown in Figure 2 , in the implementation process of the present application, the control signal is taken as the input of the inductance-capacitance (LC) filter in step e, and the filtering processing of the control signal is realized.

[0090] In the embodiment of the present application, the intelligent heating control method of the hydrogen thyratron further includes over-temperature protection and over-current protection.

[0091] Referring to Figure 2 , in the implementation process of the present application, the above-mentioned step corresponds to step f protection in Figure 2 .

[0092] Wherein, the over-temperature protection can include: presetting the maximum allowable temperature of the hydrogen thyratron, when the real-time temperature of the hydrogen thyratron exceeds the maximum allowable temperature, the control system immediately blocks the PWM pulse, the duty ratio drops to 0, and the heating power supply is turned off.

[0093] In some embodiments, the maximum allowable temperature of the hydrogen thyratron is 110 degrees Celsius.

[0094] It can be understood that, since the hydrogen pressure inside the hydrogen thyratron is positively correlated with the temperature, when the temperature exceeds the maximum allowable temperature, it can cause the hydrogen storage device to excessively release hydrogen, the pressure in the pipe to rise sharply, the sealing in the pipe to fail, the electrodes to ablate, and even the pipe body to burst, and other serious faults; at the same time, high temperature can damage the insulation performance of the hydrogen thyratron, increasing the risk of internal breakdown. The over-temperature protection cuts off the heating source by instant power-off, preventing the temperature from continuing to rise and avoiding the core components from being scrapped. The hydrogen thyratron is mainly used in high-voltage pulse power systems, and if it has problems such as leakage and breakdown due to high temperature, it can conduct faults to other modules (such as trigger circuits and high-voltage power supplies) of the system, causing the entire pulse power system to malfunction. The over-temperature protection quickly isolates the fault source to prevent risk spreading and ensure the overall operation safety of the system. Without real-time manual monitoring of the temperature of the hydrogen thyratron, the protection function can automatically identify the risk of exceeding the limit and perform protection actions, reducing the need for manual intervention and the probability of human error.

[0095] In the embodiments of the present application, the over-current protection can include: presetting an over-current protection value of the heating power supply of the hydrogen thyratron, and when the output current of the heating power supply of the hydrogen thyratron is higher than the over-current protection value in a fault condition, the control system immediately closes the PWM pulse, and the heating power supply enters the hiccup mode. After the fault is eliminated, the control system immediately opens the PWM pulse, and the heating power supply automatically recovers to normal.

[0096] It can be understood that the hiccup mode of the heating power supply is an over-current or short-circuit protection mechanism that balances protection and system recovery by periodically attempting to restart, mainly applied in switching power supplies. The core function is to intermittently shut down the output when over-current or short-circuit is detected, and if the fault is still detected after multiple attempts, the power supply will be completely turned off. This mode can not only avoid continuous downtime caused by transient faults (such as sudden inrush current), but also reduce the risk of component damage. After the over-current is no longer detected, the power supply can automatically recover to normal.

[0097] In some embodiments, the current of the heating power supply of the hydrogen thyratron is within 25A, and the over-current protection value can be set to about 30A.

[0098] It can be understood that, in a fault condition (such as short circuit of the heating power supply of the hydrogen thyratron or damage of the line insulation), the output current of the heating power supply can be far beyond the normal range, causing the power switch device (MOSFET / IGBT) and the line wire to be burned due to over-current and high temperature. The over-current protection cuts off the current by instantaneously shutting down the PWM, preventing the components from being damaged due to overheating and reducing maintenance costs.

[0099] Unlike rigid protection that shuts down completely once overcurrent occurs, the hiccup mode can distinguish between transient faults (such as start-up inrush current, temporary line disturbance) and persistent faults (such as permanent short circuit) by periodically attempting to restart: if it is a transient fault, the power supply can automatically resume normal operation after troubleshooting, avoiding long-term system downtime due to accidental disturbance; if it is a persistent fault, the power supply is completely shut down after multiple attempts to restart, preventing the fault from expanding and reducing unnecessary manual restart operations, thereby improving the fault tolerance and stability of the system.

[0100] Overcurrent protection does not require manual troubleshooting, can monitor current in real time and trigger protection action instantly, avoiding the deterioration of faults caused by persistent overcurrent (such as sparks and smoke caused by short circuits), and the automatic recovery design after troubleshooting can quickly restore normal operation of the system, reducing the impact of faults on the working time sequence of the hydrogen thyratron.
