The invention discloses a discharge tube with controllable discharge frequency and a manufacturing method therefor. The discharge tube comprises a ceramic circular substrate, a negative electrode end cover, a positive electrode end cover, a negative electrode, a trigger electrode, a ceramic cylinder, a negative electrode binding post, a positive electrode and a positive electrode binding post. The discharge tube is provided with the trigger electrode; when the discharge tube is in use, the trigger electrode is connected with a high voltage pulse control generator; when the trigger electrode receives high voltage pulse signals, the trigger electrode sends the high voltage pulse to the negative electrode to boost the voltage at the two ends of the discharge tube to breakdown gas among electrodes so as to realize ignition discharge. The discharge tube with such structure can improve the discharge voltage scope as well as can control the discharge frequency; and a plurality of the discharge tubes may work synchronously, and the reliability of igniters is improved. The manufacturing method for the discharge tube is easy to implement, high in production efficiency and can guarantee the capacity.
Description
technical field [0001] The invention relates to the technical field of discharge tubes, in particular to a discharge tube with controllable discharge frequency and a manufacturing method thereof. Background technique [0002] At present, the basic structure of the traditional high-energy ignition gas discharge tube is a closed tube body, in which there are two parallel and centered electrodes, and a certain amount of working gas is filled. According to the required discharge voltage, the distance between the electrodes and the type and pressure of the working gas are designed according to the electron flow theory and Paschen's law. When working, add a high voltage to the ignition system to charge the energy storage capacitor. Since the discharge tube is connected in parallel with the energy storage capacitor, the voltage at both ends of the discharge tube also rises. When the voltage at both ends of the discharge tube exceeds the ignition voltage, the gas between the electr...
