A multi-branch delayed discharge high voltage power supply and discharge method

Abstract

The invention discloses a multi-branch delayed discharge high-voltage power supply and a discharge method, and aims to provide a power supply and a discharge method in which the discharge voltage and the delayed discharge time can be adjusted. The power supply is composed of a discharge system and a control system. The discharge system is composed of N discharge branches connected in parallel. Each discharge branch is composed of a high-voltage module, a charging switch, a charging protection resistor, a thyristor, an explosive bridge wire, a voltmeter, a capacitor, and a short circuit switch. Composed of short-circuit protection resistors, the control system is composed of a display screen, a charging module, a discharging module, a short-circuit module, and a display module. The invention can charge voltages of different sizes to the capacitors of multiple branch circuits in parallel, so that the multiple branch circuits can output energy of different sizes and form a plurality of bubbles of different sizes in the water. The high-level signal output by the control system can be quickly turned on by the thyristor to control the discharge time of each branch capacitor, so as to realize the accurate and controllable discharge time of multiple branches, thereby controlling the generation time interval of multiple bubbles.

Description

technical field [0001] The invention relates to a time-delay energy release device, in particular to a high-voltage power supply with multiple channels capable of instantaneous discharge at different times. Background technique [0002] Underwater bubbles have important applications in medical, cleaning, marine and military fields. In the medical field, the high-speed jet generated by the interaction of two micron-sized bubbles can be used for cell membrane perforation and drug delivery. Ultrasonic waves are used to generate a large number of bubbles in the liquid, and the complex interaction between the bubbles and the bubbles and the wall can have a cleaning and disinfection effect. Cavitation bubbles are generated during the rotation of the ship's propeller, and the jets generated by these bubbles during the collapse process may corrode the propeller. In military affairs, the bubble pulsation and jet flow generated by near-field explosions may cause overall damage to th...

AI Technical Summary

Problems solved by technology

[0004] In the spark bubble experiment, due to the lack of multi-channel high-voltage power sources that can delay discharge, when studying the interaction between different bubbles, only multiple power sources can be used to discharge, and the time interval of different power discharges cannot be adjusted independently, so it is very difficult It is difficult to precisely control the generation time of bubbles of different sizes underwater

But there is no public report on the high-voltage power supply of the instantaneous discharge that can control the discharge time and the discharge voltage size at present
