Description

technical field [0001] The invention relates to a radio frequency external trigger method of a gas discharge tube and a gas discharge tube switch, more specifically, to a method for using radio frequency to externally trigger the electrical conduction of a gas discharge tube and a radio frequency external trigger gas discharge switch, which are widely used in shock Gas discharge switches in systems such as current wave generators, impulse voltage wave generators, accelerators, strong lasers, and radars. Background technique [0002] Impulse current wave generators or impulse voltage wave generators are very versatile. The switch is the main building block in the structure of impulse current wave generator or impulse voltage wave generator. Through the on and off of the switch, electric pulses are generated to form electromagnetic impact energy, even huge electromagnetic impact energy.

Problems solved by technology

The biggest disadvantages of this ball gap discharge method and its device are: high noise, large energy loss, and difficulty in regulating the ball gap discharge gap.

[0006]① Due to the two discharge gaps (anode-grid, grid-cathode), the power consumption is still too large. If the single gap voltage drop is 20V~30V, The voltage drop between the two gaps will double to 40V~60V, the power consumption will inevitably double, and the energy loss will be large

[0007]② Due to the large power consumption, the supporting auxiliary facilities are bound to increase, resulting in an increase in manufacturing costs

[0008]③ Since the hydrogen thyratron is filled with hydrogen gas, the conductivity of hydrogen gas is low (compared with argon gas, only a few tenths of that of argon gas), To maintain a certain conductivity, there must be a sufficiently large charge passing surface, and the volume of the entire hydrogen thyratron must be large enough, so that the miniaturization of the hydrogen thyratron and its switch encounters insurmountable obstacles, and it becomes a hydrogen thyratron and a hydrogen thyratron. The technical bottleneck of its switch miniaturization

[0009]④The anode and cathode of the hydrogen thyratron must be electrically connected to the positive and negative electrodes of the external circuit respectively, that is to say, the electrodes of the hydrogen thyratron have polarity For the difference, you can’t make a mistake when connecting with the circuit, which will bring inconvenience to the design and actual operation.

And above-mentioned ball gap discharge method and its switch, hydrogen thyratron method and hydrogen thyratron, all can not meet the requirement because of its own technical defect
