Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
A hydrogen thyratron detection system includes a power supply 100, a signal generator 200, and an oscilloscope 300. As shown in fig. 1, the output end of the power supply 100 is connected with the hydrogen storage and the cathode of the hydrogen thyratron 400, and is used for heating the hydrogen storage and the cathode of the hydrogen thyratron; the output end of the signal generator 200 is connected with the grid electrode of the hydrogen thyristors 400 and is used for sending trigger signals to the hydrogen thyristors at different moments; the input end of the oscilloscope 300 is connected with the output end of the signal generator 200 and is used for capturing and indicating a trigger signal. The signal generator sends a first trigger signal in a state that the hydrogen thyristors are not heated, and sends a second trigger signal in a state that the hydrogen thyristors are heated; the oscilloscope captures a first trigger signal and a second trigger signal, indicating the magnitude and time of occurrence of the first trigger signal and the second trigger signal. The first trigger signal and the second trigger signal are square wave pulse signals, the square wave pulse signals are more than or equal to 5kv, and the pulse width is in microsecond level. The power supply is an adjustable direct current high-voltage source, and the working range is 0-20kv.
The specific detection process is as follows:
in the unheated state of the hydrogen thyristors, the signal generator sends a first trigger signal, the oscilloscope captures the first trigger signal in a trigger mode, and the signal is set to a reference signal value, namely a cold state signal of a gate of the hydrogen thyristors, as shown in fig. 2;
after the first trigger signal is captured, a power supply is started to preheat a hydrogen storage device and a cathode of the hydrogen thyristors, so that the hydrogen thyristors reach a normal working state of a thermal state;
in the heating completion state of the hydrogen thyristors, the signal generator sends a second trigger signal, and the oscilloscope captures the second trigger signal in a trigger mode, wherein the signal is an ignition trigger signal of the grid electrode of the hydrogen thyristors;
according to the first stage of the working process of the hydrogen thyristors, after the grid electrode receives the second trigger signal, the grid voltage is gradually increased, and the grid current is gradually increased. When the grid current is increased to the grid ignition current, the grid starts to ignite, the grid current obviously increases suddenly, and the grid voltage rapidly decreases. Therefore, the value of the second trigger signal (shown by a dotted line in fig. 3) measured by the oscilloscope is smaller than the value of the reference signal (shown by a solid line in fig. 3), and the peak arrival time of the pulse signal is within the pulse rising time interval of the value of the reference signal, so that the result shows that the pulse signal meets the requirement of the gate ignition stage description of the hydrogen thyristors as shown in fig. 3, and the hydrogen thyristors are judged to be qualified. At intervals thereafter, a square wave pulse is sent with a signal generator, the signals of which oscilloscopes should all be as shown in fig. 3. If the peak arrival time of the pulse signal is after the pulse rising time interval of the reference signal value, the hydrogen thyristors are judged to be unqualified, and the thermal state signal waveform after the preheating of the unqualified hydrogen thyristors is completed is shown in the following figure 4.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present application without departing from the spirit or scope of the application. Thus, if such modifications and variations of the present application fall within the scope of the claims and the equivalents thereof, the present application is intended to cover such modifications and variations.
