Jitter-recording trigger tube type switch conduction process equivalent modeling method and system

The invention discloses a trigger tube type switch conduction process equivalent modeling method and system remembering jitter, and the method comprises the steps: obtaining structure parameters, gas parameters and conduction characteristics of a trigger tube type switch, and carrying out the Monte Carlo analysis of spark resistance and breakdown time delay; establishing a discretized dispersive generation array, and generating probability distribution and jitter required by fast and slow conduction mode random selection and a time delay model; building two parallel branches, controlling the conduction of the two branches through node voltage of a dispersive generation array, and building a fast and slow conduction mode random selection model; the time delay characteristic of the switch is equivalent by combining dispersive node voltage generated by the array and a self-packaged voltage-controlled resistor and controlling a capacitor charging time constant through working voltage; and extracting a gap conduct
