Description

Technical Field

[0001] The present disclosure belongs to the technical field of high-voltage fast switching, and in particular relates to an adaptive hydrogen thyratron drive system and a control method. Background Art

[0002] A hydrogen thyratron is an electron tube, a type of gas discharge tube, which can use the blocking characteristics of hydrogen when it is discharged under high voltage to control and amplify the current. It is a metal tube shell with a heating wire inside and filled with titanium hydrogen compound powder, and the tube wall has pores. When the hot wire is powered on and heated, the titanium hydrogen compound decomposes and releases hydrogen, and it has controllable electrodes and anodes. When the hydrogen thyratron is working, the heating wire needs to be powered on and kept heated at all times, so as to decompose the titanium hydrogen compound and release hydrogen.

[0003] Hydrogen thyratrons are powered by household or industrial power grids. Hydrogen thyratrons can adjust the voltage of the heating wire to ensure that they can work normally in the on state. Each type of hydrogen thyratron has a clear range of requirements for the voltage of the heating wire, so the operation of hydrogen thyratrons requires a stable power supply. The voltage of household or industrial power grids will be disturbed by the peak and trough periods of electricity consumption, resulting in unstable power supply voltage, which affects the use of hydrogen thyratrons.

[0004] If the voltage of the heating wire is not within the technical requirements of the hydrogen thyratron, the heating process of the hydrogen thyratron is improper or excessive, which may affect the service life of the hydrogen thyratron. The specific impact is as follows: if the voltage of the heating wire is too low, the heating process of the hydrogen thyratron is improper, the heating time is insufficient, the titanium hydrogen compound powder cannot be completely decomposed, resulting in insufficient hydrogen production, which in turn affects the printer transmission power of the hydrogen thyratron and cannot reach the designed working state; if the voltage of the heating wire is too high, it will cause the temperature of the hydrogen thyratron to be too high, thereby accelerating the aging process, affecting the service life, and even causing the internal pressure of the hydrogen thyratron to be too high, resulting in the destruction of the vacuum and affecting the operation. Summary of the invention

[0005] The purpose of the present disclosure is to provide an adaptive hydrogen thyratron drive system and control method, so as to solve at least part of the above technical problems.

[0006] A first aspect of the disclosed embodiment provides an adaptive hydrogen thyristor drive system, the drive system comprising a hydrogen thyristor, a first rectifier and filter module for converting an AC grid power supply into a DC voltage, a MOS tube for controlling the triggering of the hydrogen thyristor, a first transformer for voltage conversion, a control module for receiving an external command and controlling the triggering module to generate a pulse signal, a triggering module for receiving a pulse signal of the control module and amplifying and controlling the MOS tube, a relay module for selectively switching the input gear of the first transformer according to the instruction of the control module, a second transformer for providing a stable voltage for the heating wire of the hydrogen thyristor, a third transformer for providing an isolated power supply for the control module, and a second rectifier and filter module for converting the AC output of the second transformer into a DC voltage to supply the heating wire of the hydrogen thyristor;

[0007] Among them, the output of the first rectifier and filter module is connected to the drain of the MOS tube and the primary of the first transformer, the gate of the MOS tube is connected to the trigger module, the secondary of the first transformer is connected to the trigger end of the hydrogen thyristor, the control module is connected to the relay module and the trigger module, the output end of the relay module is connected to the primary of the first transformer to select different input gears, the primary of the second transformer is connected to the grid power supply, the secondary is connected to the second rectifier and filter module, the output end of the second rectifier and filter module is connected to the heating wire of the hydrogen thyristor, the primary of the third transformer is connected to the grid power supply, and the secondary provides a stable DC voltage for the control module. The control module automatically adjusts the relay module according to the change of the grid voltage to maintain the stability of the voltage at both ends of the hydrogen thyristor.

[0008] The main technical effect achieved by the embodiment of the present disclosure is that the adaptive hydrogen thyratron drive system realizes precise control of the voltage at both ends of the hydrogen thyratron through the integrated control module and relay module. Specifically, when the grid power supply voltage fluctuates, the system can monitor these changes through the control module and automatically adjust the relay module to switch the input gear of the first transformer. Such a design keeps the voltage at both ends of the hydrogen thyratron at a suitable stable level, thereby ensuring the stable operation and efficient energy conversion of the hydrogen thyratron; in addition, the system also converts the AC grid power supply into a DC voltage through the first rectifier and filter module to provide the voltage required for triggering the MOS tube. The control module is also responsible for receiving the feedback signal from the second rectifier and filter module, and further adjusting the output of the first rectifier and filter module to adapt to the working requirements of the hydrogen thyratron. This closed-loop control strategy improves the response speed and regulation accuracy of the system, and reduces the risk of performance degradation or damage of the hydrogen thyratron due to grid fluctuations.

[0020] Optionally, the control method further includes:

[0021] The control module stores historical grid power supply voltage data and analyzes this data to predict voltage change trends;

[0022] Based on the prediction results, the control module pre-adjusts the working state of the relay module to maintain the stability of the voltage across the hydrogen thyristor.

[0045] like Figure 1 As shown, the first aspect of the embodiment of the present disclosure provides an adaptive hydrogen thyristor 600 driving system, the driving system includes a hydrogen thyristor 600, a first rectifier filter module 100 for converting an AC grid power supply into a DC voltage, a MOS tube for controlling the triggering of the hydrogen thyristor 600, a first transformer T1 for voltage conversion, a control module 200 for receiving an external command and controlling the trigger module 300 to generate a pulse signal, a trigger module 300 for receiving a pulse signal of the control module 200 and amplifying and controlling the MOS tube, a relay module 400 for selectively switching the input gear of the first transformer T1 according to the instruction of the control module 200, a second transformer T2 for providing a stable voltage for the heating wire of the hydrogen thyristor 600, a third transformer T3 for providing an isolated power supply for the control module 200, and a second rectifier filter module 500 for converting the AC output of the second transformer T2 into a DC voltage to supply the heating wire of the hydrogen thyristor 600;

[0046] Among them, the output of the first rectifier and filter module 100 is connected to the drain of the MOS tube and the primary of the first transformer T1, the gate of the MOS tube is connected to the trigger module 300, the secondary of the first transformer T1 is connected to the trigger end of the hydrogen thyristor 600, the control module 200 is connected to the relay module 400 and the trigger module 300, the output end of the relay module 400 is connected to the primary of the first transformer T1 to select different input gears, the primary of the second transformer T2 is connected to the grid power supply, and the secondary is connected to the second rectifier and filter module 500, the output end of the second rectifier and filter module 500 is connected to the heating wire of the hydrogen thyristor 600, the primary of the third transformer T3 is connected to the grid power supply, and the secondary provides a stable DC voltage for the control module 200, and the control module 200 automatically adjusts the relay module 400 according to the change of the grid voltage to maintain the stability of the voltage across the hydrogen thyristor 600.

[0047] The adaptive hydrogen thyristor 600 driving system realizes precise control of the voltage across the hydrogen thyristor 600 through the integrated control module 200 and the relay module 400. Specifically, when the grid power supply voltage fluctuates, the system can monitor these changes through the control module 200 and automatically adjust the relay module 400 to switch the input gear of the first transformer T1. Such a design keeps the voltage across the hydrogen thyristor 600 at a suitable stable level, thereby ensuring the stable operation and efficient energy conversion of the hydrogen thyristor 600; in addition, the system also converts the AC grid power supply into a DC voltage through the first rectifier and filter module 100 to provide the voltage required for triggering the MOS tube. The control module 200 is also responsible for receiving the feedback signal from the second rectifier and filter module 500, and further adjusting the output of the first rectifier and filter module 100 to adapt to the working requirements of the hydrogen thyristor 600. This closed-loop control strategy improves the response speed and regulation accuracy of the system, and reduces the risk of performance degradation or damage of the hydrogen thyristor 600 due to grid fluctuations.

[0048] Through this adaptive control method, the system not only improves the working efficiency of the hydrogen thyratron 600, but also extends its service life, while also improving the reliability and stability of the entire drive system. This is particularly important for applications that require high-reliability power supplies, such as medical equipment, communication base stations, and industrial control systems.

[0049] As an optional implementation, the drive system further includes a resistor R1 and a resistor R2 connected in parallel to each other; the resistor R1 and the resistor R2 are connected between the output end of the first rectifier filter module 100 and the drain of the MOS tube. The MOS tube may encounter a sharp change in current during the switching process, which may cause damage to the device. The parallel connection of resistors R1 and R2 provides an additional protection mechanism to protect the MOS tube by limiting the current. This current limiting effect can reduce the impact of grid fluctuations or current mutations during the switching process on the MOS tube, thereby improving the safety and reliability of the system.

[0050] As an optional embodiment, the drive system also includes a resistor R3 and a resistor R4 connected in parallel with each other; the resistor R3 and the resistor R4 are connected between the output end of the second rectifier filter module 500 and the heating wire of the hydrogen thyratron 600. The heating wire of the hydrogen thyratron 600 requires a stable current to maintain a suitable operating temperature. The parallel connection of resistors R3 and R4 helps to stabilize the current of the heating wire and prevent the heating wire from overheating or uneven heating due to current fluctuations. This stable heating is essential to maintaining the performance of the hydrogen thyratron 600, and also helps to prevent premature aging or damage of the device due to temperature fluctuations.

[0051] Continue to refer Figure 1 The second aspect of the embodiment of the present disclosure provides a control method for an adaptive hydrogen thyristor 600 driving system; wherein the first rectifier and filter module 100 is used to rectify and filter the network power supply signal into a large DC voltage. The first rectifier and filter module 100 is connected to an external network power supply, and the module rectifies and filters the signal into a large DC voltage, and uses R1 and R2 resistors in parallel to limit the current, and then connects the drain of Q1 and one end of the first transformer T1.

[0052] The control module 200 is connected to the external communication protocol, receives commands from the outside, and then controls the trigger module 300 to modulate the small pulse signal; the control module 200 also receives a signal from the parallel connection of resistors R3 and R4, and controls the relay module 400 to select to open the switch according to the signal.

[0053] The trigger module 300 is used to modulate the pulse signal according to the received command. After receiving the command from the control module 200, the trigger module 300 modulates the pulse signal and connects to the second transformer T2.

[0054] The relay module 400 is used to connect the grid power supply to the third transformer T3. According to the command from the control module 200, one of the relay switches is turned on to connect the grid power supply to the input gear of T3.

[0055] The second rectifying and filtering module 500 is used to rectify and filter the AC signal into a small DC voltage. The second rectifying and filtering module 500 is connected to the heating wire of the hydrogen thyristor 600600 and the resistor R3, rectifying the AC voltage of the heating wire of the hydrogen thyristor 600600 into a small DC voltage, and limiting the current by connecting the resistors R3 and R4 in parallel.

[0056] When the system is running, the control module 200 opens one of the switches of the relay module 400 by default, so that the network power supply is connected to the 220V gear input end of the third transformer T3, and the cathode and hydrogen storage of the hydrogen thyristor 600 are heated through the third transformer T3. The second rectifier and filter module 500 rectifies and filters the stabilized AC voltage of the heating filament into a small DC voltage, and limits the current in parallel through resistors R3 and R4, and then feeds it back to the control module 200. At the same time, after the first rectifier and filter module 100 receives the AC voltage of the network power supply, it becomes a large DC voltage through rectification and filtering. After the R1 and R2 resistors limit the large DC voltage in parallel, they are connected to the source of Q1 of the MOS tube and the first transformer T1, waiting for the gate signal of the MOS tube.

[0057] The DC voltage fed back to the control module 200 is proportional to the grid power supply. The control module 200 then turns on the corresponding relay group switch of the relay module 400 and connects to the third transformer T3 according to the actual DC voltage received. For example, when the AC voltage of the grid power supply is 217V, the corresponding relay group switch of the relay module 400 should make the gear of the third transformer T3 at 220V. When the control module 200 receives a command from the external communication protocol, the control module 200 immediately sends a command to the trigger module 300, and the trigger module 300 immediately generates a small pulse signal, which is amplified by the second transformer T2 and controls the gate of the MOS tube Q1, so that the DC large voltage connecting the source of the MOS tube Q1 and the pulse transformer T1 becomes a large voltage pulse signal. After the large voltage pulse signal is amplified by the first transformer T1, it becomes a high-voltage trigger signal input to the gate of the hydrogen thyristor 600, and the hydrogen thyristor 600 outputs a high-voltage pulse through the externally connected DC high voltage HV.

[0058] The control method can make the hydrogen thyratron 600 effectively adapt to the grid power supply of various environments, thereby effectively reducing the abnormal working conditions of the hydrogen thyratron 600 and effectively extending the service life of the hydrogen thyratron 600, so that the hydrogen thyratron 600 can be used for a longer time.

[0059] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the scope of protection of the present disclosure.
