Description

Technical Field

[0001] The invention relates to the technical field of pulse power, and in particular to a universal high-power pump xenon lamp detection power supply. Background Art

[0002] Pulse power technology has been widely used in many fields such as accelerators, radar transmitters, safety inspections, industrial non-destructive testing, controlled nuclear fusion, etc. The application of high-power pulsed xenon lamps is also based on pulse power technology. With the development of science and technology, the application of high-power pumped xenon lamps has become more and more extensive in recent years, such as chemical coating curing, ink curing, sterilization, photolithography, high-speed photography, laser cleaning and controlled nuclear fusion.

[0003] The pulse discharge characteristic indicators of high-power pumped xenon lamps, such as energy density, transmission efficiency, and pump consistency, directly affect and determine the application of high-power pumped xenon lamps, while the indicators of high-power pumped xenon lamps, such as gas filling pressure, withstand voltage, pulse width, peak current, and explosion energy, determine the service life of the pumped xenon lamp and the stability of the device operation. Because high-power pumped xenon lamps are widely used, they are filled with inert gas and the application belongs to the process of plasma discharge. In addition, the arc length, inner diameter, and gas filling pressure of the xenon lamp are affected by the processing and manufacturing process and manufacturing accuracy, which will lead to inconsistency, shortened service life, and unstable output of the pumped xenon lamp. According to the different application requirements of high-power pumped xenon lamps, the lamp length, inner diameter, and gas pressure of the xenon lamp are inconsistent, and the indicators of its pulse discharge characteristics need to be determined according to the parameters of the capacitor, resistor, and inductor in the pump source and the system loop distribution parameters.

[0004] Therefore, the detection of high-power pumped xenon lamps is still limited by high-power laser pump sources. Different xenon lamps need to be customized with different pump sources after calculation and simulation according to their operating modes and parameters, and this type of power supply can only meet the setting of a single mode explosion coefficient. First, the main index test of xenon lamps by xenon lamp manufacturers can only be based on the static parameter test of xenon lamp arc length, inner diameter, air pressure, etc.; secondly, the end customers carry out pulse discharge characteristic tests based on xenon lamp applications. Different high-power pumped xenon lamps need to be customized with high-power pump sources that meet their pulse discharge characteristics according to their specific electrical parameters of the circuit, and this type of power supply is difficult to achieve and meet different explosion coefficient requirements, and cannot be switched among pumped xenon lamps of various specifications and models. When meeting the needs of conventional tests, it is impossible to carry out xenon lamp life tests under a certain explosion coefficient, and different pump sources need to be customized for pumped xenon lamps of different specifications and models, which is very costly. Therefore, it is difficult to carry out a comprehensive application evaluation of static parameters, pulse discharge characteristics and life of high-power pumped xenon lamps. The development and application of xenon lamps can only rely on data collection from end users. There are many uncertainties in the development process of pump xenon lamps, and it is very easy for batches to be scrapped due to unqualified quality.

[0005] Therefore, traditional pump power supplies need to be customized individually and cannot be compatible with different pump xenon lamp models and specifications, and cannot be universal. Summary of the invention

[0047] The charging control cabinet is composed of two sets of main and pre-charging power supplies, a control unit and an acquisition unit. The main and pre-charging power supplies provide 0-40kV charging energy storage for the energy storage cabinet energy storage capacitor respectively. Pre-charging can realize the pre-ionization of the pump xenon lamp and provide a plasma discharge channel for the main pulse discharge, accelerate the formation of the plasma channel, make the main pulse discharge more uniform, and improve the radiation efficiency of the pulse discharge of the pump xenon lamp. The control unit realizes the detection of power supply parameter settings, parameter simulation calculations, and mode switching.

Different xenon lamp loads require appropriate loop distribution parameters, and loop parameters are allocated according to the pulse discharge requirements and the discharge loop requirements. After determining the pump xenon lamp model and the pulse discharge characteristics that need to be carried out, automatic matching is achieved through S1`~Sn, RL1~RL17 and C1~C17. The number of load loops needs to be combined with the modulation inductor L1~L5 to achieve single-loop to 5-loop load output requirements, and the system loop is matched through series and parallel connections.

[0054] like Figure 2 , 3As shown, No. 2 and No. 4 are energy storage cabinets. The two cabinets are symmetrically arranged on both sides of No. 3 switch discharge cabinet, mainly providing charging protection R1 and R1`, current limiting protection D1 and D1`, reverse peak protection D2 and D2` for the system. The loop switching switches S1`~Sn`, protection inductors RL1~RL17 and energy storage capacitors C1~C17 provide high-voltage energy storage for the system and are symmetrically arranged. Under the control of the control system, the energy storage cabinet realizes automatic busbar switching selection through the loop switching switch to complete the scheme selection of different test operation parameters. For universal application and convenience, only the loop protection components need to be switched to complete the test parameter matching; the protection inductors RL1~RL17 can absorb the loop energy storage capacity when the energy storage capacitor is short-circuited and broken down, withstand the impact of large fault current, and prevent secondary damage to the equipment. No. 3 is a switch discharge cabinet, which uses all-solid-state discharge switch components S1 and S2 inside. The discharge switch components are composed of solid thyristor devices in series, which can meet the pulse discharge requirements of rated withstand voltage 60kV and pulse discharge current 330kA. The discharge switches S3 and S4, discharge resistors Rx and Rx1 together constitute the discharge unit to ensure the safety of the system and operators; the modulating inductors L1~L5 constitute the load output circuit, which can achieve matching output from single circuit to 5 circuits. By switching the modulating inductors with different parameters, the matching requirements of different xenon lamp load parameters can also be met; the modulating inductor can absorb fault energy to protect the safety of equipment in the event of abnormal short circuit at the cable end and short circuit of the load xenon lamp; the waveform acquisition adopts Rogowski coil integral sampling. The Rogowski coil takes the load branch discharge current pulse, which is integrated by the integral board and sent to the control unit for acquisition calculation to ensure the acquisition accuracy.

[0055] No. 5 is an energy storage expansion cabinet, which is mainly used for the needs of pump xenon lamp expansion test. It is equipped with energy storage capacitors and protective inductors. It can be quickly connected to the system through high-voltage busbars to meet the matching requirements of pulse discharge characteristic parameters of different load parameters; No. 6 is a xenon lamp load cabinet, which uses quick connection terminals to achieve fast replacement of xenon lamps of different specifications and models. The internal structure design uses quick connection terminals, and the internal height can be quickly adjusted to achieve installation convenience between 380 and 2150 mm for different xenon lamp loads. The connection terminals use butterfly connection mode, which is convenient for operators to operate quickly. It can realize the accelerated life test of a single xenon lamp, the normal operation mode test of two lamps in series, the pulse discharge characteristic test of two lamps in series, the output efficiency test of pump source, the normal operation mode of multiple lamps in series, the output pulse discharge characteristic test of multiple circuits, the rated operation life test of multiple circuits and the pump inconsistency test, etc. The quick connection terminal in the xenon lamp load cabinet is connected to the output end of the discharge cabinet, and is connected to the xenon lamp to be tested through the quick connection terminal.

[0056] like Figure 3As shown in the figure, the internal layout of a universal high-power pump xenon lamp detection power supply, serial numbers 7 to 10 are busbars for adjusting the internal parameters of the detection power supply. By adopting a mechanical high-current conduction switch, under the control of the control extension, the corresponding busbars are automatically selected to form the main circuit link according to the load xenon lamp operation mode, the parameter environment required to operate, the explosion coefficient and other parameters to meet the requirements of the detection power supply operation parameters. Serial number 11 is the busbar of the energy storage expansion cabinet, which can be expanded and selected according to the pump pulse energy, efficiency and pulse discharge characteristics of the load xenon lamp. Serial number 12 is a modulating inductor component. The number of modulating inductors is determined according to the number of user load detection loops, and the appropriate modulating inductor is selected according to the load parameters to participate in the detection. The modulating inductor has the function of matching the pulse waveform. In the case of short circuit of the output cable and abnormal short circuit of the xenon lamp, it absorbs the circuit fault energy and protects the equipment. This solution can achieve the advantages of universality and compatibility, that is, through the free matching of serial numbers 7 to 12, the explosion coefficient adjustment and test mode selection of the pump xenon lamp under different specifications and technical indicators are met and realized. The core is to select appropriate parameters through calculation and simulation, and use the above scheme to meet the requirements of xenon lamp loads of different specifications and models, and to carry out pump xenon lamp testing under different explosion coefficients and different experimental modes. After determining the parameters of the energy storage capacitor and the protective inductor, you can simply adjust the serial numbers 7 to 10 to achieve compatibility and universality. For pump xenon lamps with special parameters, the energy storage and protective inductor parameters can be expanded through serial number 11 to simply achieve.

[0057] like Figure 4As shown in the figure, it is a software control logic diagram of a general high-power pump xenon lamp detection power supply. The charging control cabinet communicates with the main and pre-charging extensions respectively, and controls the main and pre-charging extensions to charge the main and pre-energy storage capacitors respectively. After the voltage on the energy storage capacitor reaches the system setting voltage, the synchronous trigger signal controls the main and pre-discharge switches to conduct and discharge. The waveform acquisition system collects the load current pulse through the current transformer, sends it to the data acquisition for data processing, and then transmits it to the control extension for waveform reading and judgment, and transmits it to the host computer for waveform interpretation and data display. The host computer software has the functions of operating parameter setting, system parameter configuration, automatic detection, automatic calibration, operating mode selection, operating status alarm, abnormal status processing and database management. The user sets the operating parameters according to the parameters of the xenon lamp under test. The host computer software calculates the capacitance and inductance parameters of the circuit matching according to the operating mode and load xenon lamp parameters, load explosion energy, current pulse width and other parameters. The system parameter configuration sends instructions to the control extension, and the control extension controls the circuit switching switch S1`~Sn` to complete the system parameter configuration. After configuration, the host computer software completes the simulation measurement and automatic detection and verification according to the built circuit to ensure that the system circuit parameters basically meet the operating parameter requirements. During the operation, the system circuit is monitored and detected in real time to ensure that the equipment status can operate normally, and the process voltage, current, and pulse waveform data are collected. According to the mode selection, loop voltage and current, and xenon lamp parameters, combined with the discharge voltage, pulse current, and pulse width at 10% and 30% during discharge, it is judged whether the xenon lamp operating parameters are normal. Through the background operation and calculation of the host computer, the system operation data judgment is given, which can realize the statistics of the effective data during the operation process, and prompt the user to replace the life device before the life device reaches the end of its service life. It is used to realize system health management, which can provide operators with the validity of the operation process data and reduce the identification and judgment of abnormal parameters by operators. Secondly, the system can realize real-time monitoring of system operation data through software status display and hardware current protection point setting, and ensure the stable operation of the system by monitoring, identifying and judging the abnormal state during the operation. It realizes the switching selection between automatic mode and manual mode, ensures the convenience and safety of the operator's operation, and improves the system operation efficiency.
