Description

Technical Field

[0001] The present application relates to the technical field of pulse power control, and in particular to an intelligent control system and method for hydrogen thyratron filament heating. Background Art

[0002] As a key component in high-power pulse modulators, the performance of hydrogen thyratrons directly affects the stability and reliability of the entire system. Filament heating is the basis for the normal operation of hydrogen thyratrons. Insufficient heating will cause the filament to be underheated, instantly destroying the thyratron; while excessive heating may cause overheating, which also affects the life of the thyratron. In addition, as the use time of hydrogen thyratrons increases, the internal hydrogen pressure will gradually decrease. It is necessary to maintain an appropriate hydrogen concentration by adjusting the heating voltage of the hydrogen generator to ensure the normal operation of the thyratron.

[0003] The existing technology for controlling the heating of hydrogen thyratron filaments mostly relies on manual adjustment or simple mechanical control, resulting in low adjustment accuracy and slow response speed for the hydrogen thyratron, making it difficult to achieve the demand for high-precision and high-stability control of the hydrogen thyratron. Summary of the invention

[0004] Based on this, it is necessary to provide an intelligent control system and method for hydrogen thyratron filament heating in view of the fact that the existing technology for controlling the heating of hydrogen thyratron filament mostly relies on manual adjustment or simple mechanical control, resulting in low adjustment accuracy and slow response speed for the hydrogen thyratron, making it difficult to achieve the demand for high-precision and high-stability control of the hydrogen thyratron.

[0005] In one aspect, the present application provides a hydrogen thyratron filament heating intelligent control system, comprising:

[0006] A detection unit, the detection unit is electrically connected to the hydrogen thyratron, and the voltage and current passing through the hydrogen thyratron are detected in real time by the detection unit;

[0007] A controller, wherein the detection unit is electrically connected to the controller;

[0008] A heating transformer, the heating transformer is arranged between the controller and the hydrogen thyratron, and the heating transformer is provided with a plurality of transformation ratios;

[0009] The regulating part is electrically connected to the controller and is arranged between the controller and the heating transformer.

[0010] On the other hand, the present application also provides a hydrogen thyratron filament heating intelligent control method, comprising:

[0011] Set voltage threshold;

[0012] Acquire the actual voltage of the hydrogen thyratron, and calculate the target transformation ratio of the heating transformer according to the actual voltage of the hydrogen thyratron;

[0013] Set the hysteresis area to determine whether the target ratio of the heating transformer is the same as the actual ratio;

[0014] If the target transformation ratio of the heating transformer is different from the actual transformation ratio, different adjustment switches of the adjustment part are adjusted by hysteresis control to adjust the actual transformation ratio of the heating transformer to the target transformation ratio.

[0015] The present application relates to an intelligent control system and method for heating a hydrogen thyratron filament. The intelligent control system for heating a hydrogen thyratron filament detects the actual voltage and actual current of the hydrogen thyratron in real time through a detection unit, and transmits the detection data to a controller. The controller determines whether it is necessary to adjust the transformation ratio of the heating transformer based on the received detection data. If it is necessary to adjust the transformation ratio of the heating transformer, the actual transformation ratio of the heating transformer is converted into a target transformation ratio by adjusting the adjustment unit to adjust the actual voltage and actual current of the hydrogen thyratron. The present application adjusts the transformation ratio of the heating transformer through the controller, and thereby adjusts the actual voltage and actual current of the hydrogen thyratron, thereby achieving precise control of the hydrogen thyratron, avoiding underheating or overheating of the hydrogen thyratron filament, and achieving higher regulation efficiency.

[0021] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] The present application provides a hydrogen thyratron filament heating intelligent control system and control method.

[0023] like Figure 1As shown, in one embodiment of the present application, a hydrogen thyratron filament heating intelligent control system is provided, and the hydrogen thyratron filament heating intelligent control system includes a detection unit 100, a controller 200, a heating transformer 300 and a regulating unit 400.

[0024] The detection unit 100 is electrically connected to the hydrogen thyristor, and the voltage and current passing through the hydrogen thyristor are detected in real time by the detection unit 100. The detection unit 100 is electrically connected to the controller 200. The heating transformer 300 is arranged between the controller 200 and the hydrogen thyristor, and the heating transformer 300 is provided with a plurality of transformation ratios. The regulating unit 400 is electrically connected to the controller 200, and the regulating unit 400 is arranged between the controller 200 and the heating transformer 300.

[0025] Specifically, the transformation ratio includes transformer ratio, voltage transformer ratio and current transformer ratio. The transformation ratio K (i.e., voltage ratio) of the transformer is the ratio of the high-voltage winding voltage U1 to the low-voltage winding voltage U2 under the no-load condition of the transformer. The voltage ratio between the primary winding and the secondary winding of the voltage transformer or the current ratio between the primary winding and the secondary winding of the current transformer.

[0026] In this embodiment, the actual voltage and actual current of the hydrogen thyratron are detected in real time by the detection unit 100, and the detection data is transmitted to the controller 200. The controller 200 determines whether it is necessary to adjust the transformation ratio of the heating transformer 300 based on the received detection data. If it is necessary to adjust the transformation ratio of the heating transformer 300, the actual transformation ratio of the heating transformer 300 is converted into the target transformation ratio by adjusting the adjustment unit 400 to adjust the actual voltage and actual current of the hydrogen thyratron. The present application adjusts the transformation ratio of the heating transformer 300 by the controller 200, and thereby adjusts the actual voltage and actual current of the hydrogen thyratron, thereby achieving precise control of the hydrogen thyratron, avoiding underheating or overheating of the hydrogen thyratron filament, and having higher regulation efficiency.

[0027] like Figure 1 As shown, in one embodiment of the present application, the detection unit 100 includes a current detection unit 102 and a voltage detection unit 101, and both the current detection unit 102 and the voltage detection unit 101 are electrically connected to the hydrogen thyristor.

[0028] Specifically, the current detection unit 102 is connected in series to the hydrogen thyristor, and the voltage detection unit 101 is connected in parallel to the hydrogen thyristor.

[0029] In this embodiment, the current detecting unit 102 detects the current passing through the hydrogen thyratron filament, and the voltage detecting unit 101 detects the voltage of the hydrogen thyratron filament. The detection result of the current detecting unit 102 and the detection result of the voltage detecting unit 101 are transmitted to the controller 200. The controller 200 adjusts the regulating unit 400 according to the detection result of the current detecting unit 102 and the detection result of the voltage detecting unit 101, thereby adjusting the heating voltage passing through the hydrogen thyratron filament to maintain the normal operation of the hydrogen thyratron.

[0030] like Figure 1 As shown, in one embodiment of the present application, the regulating unit 400 includes a plurality of regulating switches 401 , and the plurality of regulating switches 401 are electrically connected to different transformation ratios of the heating transformer 300 , respectively.

[0031] Specifically, the regulating switch 401 may be a normally open relay or a thyristor switch.

[0032] In this embodiment, since different adjustment switches 401 correspond to different transformation ratios of the heating transformer, the transformation ratio of the heating transformer can be adjusted by closing the corresponding adjustment switch 401 .

[0033] For example, the regulating switches 401 are respectively recorded as regulating switch K1, regulating switch K2, ..., regulating switch K5, and the transformation ratio of the heating transformer 300 corresponding to each regulating switch 401 is N1, N2, ..., N5.

[0034] Since in the actual working process, there is only one regulating switch 401 in the closed state, if the regulating switch K3 is in the closed state, then the transformation ratio of the heating transformer 300 is N3.

[0035] like Figure 2 As shown, in one embodiment of the present application, a hydrogen thyratron filament heating intelligent control method is provided, and the hydrogen thyratron filament heating intelligent control method includes:

[0036] S100, setting a voltage threshold.

[0037] Specifically, the voltage threshold is the ideal voltage. However, since there is resistance in the circuit during the actual working process, there is a certain error between the actual voltage and the ideal voltage.

[0038] S200, obtaining the actual voltage of the hydrogen thyristor, and calculating the target transformation ratio of the heating transformer according to the actual voltage of the hydrogen thyristor.

[0039] S300, setting a hysteresis region to determine whether the target transformation ratio of the heating transformer is the same as the actual transformation ratio.

[0040] S400: If the target transformation ratio of the heating transformer is different from the actual transformation ratio, different adjustment switches of the adjustment part are adjusted by hysteresis control to adjust the actual transformation ratio of the heating transformer to the target transformation ratio.

[0041] Specifically, in order to make the text concise, only the relevant embodiments of the hydrogen thyratron filament heating intelligent control system are numbered.

[0042] In this embodiment, a voltage threshold is first set, and then the actual voltage of the hydrogen thyratron is obtained. The target transformation ratio of the heating transformer is calculated according to the actual voltage of the hydrogen thyratron. Then, a hysteresis region is set to determine whether the target transformation ratio of the heating transformer is the same as the actual transformation ratio. If the target transformation ratio of the heating transformer is different from the actual transformation ratio, different adjustment switches of the adjustment part are adjusted by hysteresis control to adjust the actual transformation ratio of the heating transformer to the target transformation ratio. The present application calculates the target transformation ratio of the heating transformer by the actual voltage of the hydrogen thyratron, and converts the actual transformation ratio of the heating transformer into the target transformation ratio by hysteresis control, so that the voltage stability can always be maintained when adjusting the voltage of the hydrogen thyratron, thereby ensuring the long-term stable operation of the hydrogen thyratron.

[0043] In one embodiment of the present application, the S200 includes:

[0044] S210, obtaining the actual voltage of the hydrogen thyristor.

[0045] Specifically, the actual voltage of the hydrogen thyristor is the voltage of the hydrogen thyristor detected by the voltage detection unit.

[0046] S220, calculating the input voltage value of the heating transformer by using Formula 1 based on the actual voltage of the hydrogen thyristor.

[0047]

[0048] Among them, Vi is the input voltage value of the heating transformer, Vref is the voltage threshold, Vref+ΔV is the actual voltage value of the hydrogen thyristor, and N0 is the preset actual transformation ratio.

[0049] S230, calculating the target transformation ratio by using Formula 2 based on the input voltage value of the heating transformer.

[0050]

[0051] Among them, Vi is the input voltage value of the heating transformer, Vref is the voltage threshold, and NX is the target transformation ratio.

[0052] In this embodiment, since there is an error between the actual voltage and the voltage threshold, and this error is ΔV, the relative transformation ratio of the voltage threshold should also change after the error occurs, so as to meet the transformation ratio of the actual voltage.

[0053] In the process of adjusting the transformation ratio of the heating transformer from the transformation ratio corresponding to the voltage threshold to the target transformation ratio corresponding to the actual voltage, the input voltage value of the heating transformer is first calculated according to the actual voltage by formula 1, and then the target transformation ratio corresponding to the actual voltage is determined based on the input voltage value of the heating transformer. Since each transformation ratio has its corresponding adjustment switch, after determining the target transformation ratio, the adjustment switch that needs to be closed can be determined.

[0054] In one embodiment of the present application, the S300 includes:

[0055] S310, setting a plurality of reference low turns ratios and a plurality of reference high turns ratios, wherein each reference low turns ratio corresponds to a reference high turns ratio. The plurality of reference low turns ratios are respectively recorded as NL1, NL2, ..., NLn, and the plurality of reference high turns ratios are respectively recorded as NH1, NH2, ..., NHn.

[0056] S320, establishing n hysteresis regions based on each pair of reference low turns ratio NL and reference high turns ratio NH Multiple hysteresis regions are recorded as Y1, Y2, ..., Yn. Among them, NL is the reference low turns ratio, NH is the reference high turns ratio, A is the hysteresis coefficient, It is the middle line of the hysteresis region.

[0057] In this embodiment, the purpose of setting the hysteresis region is to reduce the situation where a small voltage change causes the opening and closing frequency of the regulating switch to be too high, thereby affecting the normal operation of the hydrogen thyristor.

[0058] In the actual working process, the voltage cannot always maintain a stable value, but will fluctuate up and down. However, the amplitude of this fluctuation may not be large. For example, the voltage fluctuation only fluctuates within 5% of the ideal voltage. If the opening and closing of the regulating switch are adjusted for each small voltage fluctuation, it will affect the normal operation of the hydrogen thyratron. Sometimes the voltage fluctuation amplitude may be relatively large. If a large voltage fluctuation occurs, the opening and closing of the regulating switch should be adjusted in time to maintain the input voltage of the hydrogen thyratron.

[0059] Therefore, the concept of hysteresis region is proposed. The existence of hysteresis region first converts the voltage fluctuation into the fluctuation of transformation ratio, and then judges whether the fluctuation amplitude of transformation ratio is within the hysteresis region, so as to judge whether the regulating switch needs to be adjusted.

[0060] When the target transformation ratio and the actual transformation ratio are in the same hysteresis region, it can be considered that the voltage fluctuation amplitude is small, so there is no need to adjust the turns ratio of the heating transformer to adapt to the voltage fluctuation, so there is no need to adjust the regulating switch.

[0061] When the target transformation ratio and the actual transformation ratio are not in the same hysteresis area, it can be considered that the voltage fluctuation amplitude is large. Therefore, the turns ratio of the heating transformer needs to be adjusted to adapt to the voltage fluctuation. Therefore, it is necessary to close the appropriate adjustment switch to make the heating transformer at a suitable turns ratio.

[0062] When setting the hysteresis area, there are two cases: one is to set multiple hysteresis areas, and the other is to set a single hysteresis area.

[0063] In this embodiment, a plurality of hysteresis regions are provided, and each hysteresis region has a relatively small range, so that the response sensitivity to the change of the transformation ratio can be improved.

[0064] The input voltage is 220V, and the input voltage fluctuates between 200V and 240V, then four hysteresis regions of 203V~207V, 213V~217V, 223V~227V, and 233V~237V can be divided, which are denoted as Y1, Y2, Y4 and Y5 respectively. The transformation ratio corresponding to each hysteresis region is N1, N2, N4 and N5 respectively, and the turns ratio corresponding to 220V is denoted as N3.

[0065] If the voltage threshold is set to 5V and A=0.2, then through step S320, the hysteresis areas can be calculated as Y1[40.6,41.4], Y2[42.6,43.4], Y4[44.6,45.4] and Y5[46.6,47.4], and the transformation ratio corresponding to each hysteresis area is N1=40, N2=42, N3=44, N4=46 and N5=48.

[0066] In one embodiment of the present application, providing S300 includes:

[0067] S330, setting a reference low turns ratio NL and a reference high turns ratio NH.

[0068] S340, build hysteresis region based on reference low turns ratio NL and reference high turns ratio NH Where NL is the reference low turns ratio, NH is the reference high turns ratio, A is the hysteresis coefficient, It is the middle line of the hysteresis region.

[0069] In this embodiment, only one hysteresis region is set. Compared with the previous embodiment, the range of the hysteresis region in this application is larger, so it is less sensitive to small fluctuations in the transformation ratio, thereby reducing the frequent changes of the regulating switch caused by small fluctuations in the transformation ratio.

[0070] In one embodiment of the present application, the S400 includes:

[0071] S410, determining whether the target transformation ratio is greater than the actual transformation ratio.

[0072] S420, if the target transformation ratio is greater than the actual transformation ratio, determine the hysteresis region where the target transformation ratio is located, open the original regulating switch, and close the regulating switch corresponding to the previous hysteresis region adjacent to the hysteresis region where the target transformation ratio is located.

[0073] Specifically, if the target transformation ratio and the actual transformation ratio are in the same hysteresis region, then there is no need to adjust the adjustment switch, and the original adjustment switch can be maintained.

[0074] In the present embodiment, for the case where multiple hysteresis regions are set, since the multiple hysteresis regions are not continuous, for example, the hysteresis region Y1 and the hysteresis region Y2 in the aforementioned embodiment, there is a fracture zone of 41.4-42.6 between the hysteresis region Y1 and the hysteresis region Y2, so for multiple hysteresis regions, there may be a situation where the target transformation ratio falls outside any hysteresis region.

[0075] For the case where the target ratio falls outside any hysteresis region, there are two cases. The first case is that the target ratio is greater than the actual ratio as described in this embodiment. When the target ratio is greater than the actual ratio and the target ratio is not in any hysteresis region, when adjusting the adjustment switch, it is necessary to close the adjustment switch corresponding to the hysteresis region with a smaller ratio number and open the original adjustment switch.

[0076] According to the hysteresis regions Y1 to Y5 described in the aforementioned embodiment, if the original input voltage is 220V, and the transformation ratio at this time is N3, the regulating switch K3 corresponding to N3 is in a closed state, and the actual voltage of the hydrogen thyratron is 5.7V, then according to Formula 1 and Formula 2, the target transformation ratio can be obtained as 47.88. The target transformation ratio exceeds the maximum value of the hysteresis region Y5 [46.6, 47.4]. It can be considered that the target transformation ratio is in the Y5 hysteresis region. Since the original transformation ratio is N3, it is necessary to disconnect the regulating switch K3 corresponding to the original N3 and close the regulating switch K5 corresponding to N5.

[0077] For a single hysteresis area, after the target ratio is calculated according to Formula 1 and Formula 2, as long as the target ratio is not in the hysteresis area, the corresponding adjustment switch can be closed according to the target ratio. If the target ratio is still in the hysteresis area, there is no need to adjust the adjustment switch, and only the original adjustment switch needs to be maintained.

[0078] In one embodiment of the present application, the S400 further includes:

[0079] S430, determining whether the target transformation ratio is smaller than the actual transformation ratio.

[0080] S440, if the target transformation ratio is smaller than the actual transformation ratio, determine the hysteresis region where the target transformation ratio is located, open the original regulating switch, and close the regulating switch corresponding to the next hysteresis region adjacent to the hysteresis region where the target transformation ratio is located.

[0081] In this embodiment, according to the hysteresis regions Y1 to Y5 described in the previous embodiment, if the original input voltage is 220V, similarly, the transformation ratio at this time is N3, and the regulating switch K3 corresponding to N3 is in a closed state, and the actual voltage of the hydrogen thyristor is 4.9V. According to Formula 1 and Formula 2, the target transformation ratio can be obtained as 41.16, which is lower than the lower limit threshold of the hysteresis region Y2 [42.6-43.4] and higher than the lower limit threshold of the hysteresis region Y1 [40.6-41.4]. It can be seen that the target transformation ratio is within the hysteresis region Y1 [40.6-41.4]. Therefore, according to S440, it is necessary to close the regulating switch corresponding to the hysteresis region Y2 [42.6-43.4] after the hysteresis region Y1 [40.6-41.4], that is, disconnect the regulating switch K3 corresponding to the original N3, and close the regulating switch K2 corresponding to N2.

[0082] However, similarly, when the target ratio is smaller than the actual ratio, there is also a situation where the target ratio is outside any hysteresis region, that is, the target ratio is smaller than the actual ratio and the target ratio is outside any hysteresis region. In order to ensure that the normal operation of the hydrogen thyratron can be maintained, the regulating switch corresponding to the hysteresis region closest to the target ratio and greater than the target ratio should be closed.

[0083] If the target transformation ratio is 41.9, which is between the hysteresis area Y1 [40.6 ~ 41.4] and the hysteresis area Y2 [42.6 ~ 43.4], then the hysteresis area closest to the target transformation ratio and larger than the target transformation ratio is the hysteresis area Y2 [42.6 ~ 43.4]. Therefore, the regulating switch K3 corresponding to the original N3 should also be opened, and the regulating switch K2 corresponding to N2 should be closed.

[0084] When the target ratio is smaller than the actual ratio, it is only necessary to determine the minimum value of which hysteresis region the target ratio is smaller than. When it is determined that the target ratio is smaller than the minimum value of the hysteresis region, the regulating switch corresponding to the hysteresis region with the smallest minimum value is closed.

[0085] When the target ratio is greater than the actual ratio, it is only necessary to determine whether the target ratio is greater than the maximum value of the hysteresis region. When it is determined that the target ratio is greater than the maximum value of the hysteresis region, the regulating switch corresponding to the hysteresis region with the largest maximum value is closed.

[0086] In one embodiment of the present application, the hydrogen thyratron filament heating intelligent control method further includes:

[0087] S510, setting a current threshold.

[0088] S520, obtaining the actual current of the hydrogen thyratron.

[0089] S530, determining whether the actual current of the hydrogen thyristor is greater than or equal to the current threshold.

[0090] S540, if the actual current of the hydrogen thyristor is greater than or equal to the current threshold, an alarm is issued.

[0091] In this embodiment, in addition to monitoring and adjusting the voltage of the hydrogen thyristor, the current of the hydrogen thyristor also needs to be monitored synchronously.

[0092] Therefore, by setting a current threshold and judging whether the actual current passing through the hydrogen thyristor is greater than or equal to the current threshold, an alarm is issued when the actual current of the hydrogen thyristor is greater than or equal to the current threshold.

[0093] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
