Embodiment Construction

[0016] As shown in FIG. 1 , the present invention includes a pulse signal generator 1 , a pulse power supply 2 , an experiment cavity 3 , a current measurement sensor 4 , a high-speed digital oscilloscope 5 , and a signal conversion circuit 6 . The fast pulse control signal generated by the pulse signal generator 1 is transmitted to the pulse power supply 2, and the pulse power supply 2 is controlled to generate high-voltage pulses, and then the high-voltage pulses are applied to the positive and negative poles of the experimental chamber 3. At the same time, the negative pole of the experimental chamber 3 is grounded through the high-voltage lead wire 28 of the current measurement sensor 4, and the discharge current of the experimental chamber 3 is directly introduced into the current measurement sensor 4. The current measurement sensor 4 can use a non-inductive resistor shunt or a Rogowski current coil. , the signal obtained by the current measurement sensor 4 is sent to a me...

Abstract

A device for real-time shutdown protection of high-voltage fast pulse signals, the pulse signal generator (1) generates a control signal for high-voltage fast pulse generation, controls the pulse power supply (2) to generate high-voltage fast pulses, and acts on the experimental chamber (3) , the discharge current of the experimental cavity (3) is introduced into the current measurement sensor (4), and the voltage signal on the current measurement sensor (4) is connected to a measurement channel of the digital oscilloscope (5), as the trigger source of the oscilloscope, a suitable trigger level. Once the medium breaks down, the discharge current is too large, and the voltage signal on the current measurement sensor (4) is enough to trigger the oscilloscope (5), then the trigger feedback port of the oscilloscope (5) will immediately output a TTL logic signal, which passes through the signal The conversion circuit (6) performs processing, outputs a signal conforming to the shutdown signal interface standard of the pulse signal generator, and turns it off, thereby playing a protective role. The time delay of the present invention can be controlled within 10 μs.

Description

technical field [0001] The invention relates to a device for real-time shutdown protection of high-voltage fast pulse discharge, in particular to a device for high-power high-voltage fast pulse discharge experiment. Background technique [0002] In recent years, with the development and wide application of high-voltage pulse technology, the research on the characteristics of related dielectrics under high-voltage fast pulse discharge has become increasingly in-depth, such as dielectric breakdown, dielectric barrier discharge applications, and electric tree development.
