Low-temperature plasma discharge power supply device

Abstract

The invention discloses a low-temperature plasma discharge power supply device. The power supply device comprises a power supply casing. A control unit, a switching power supply, an inverter, a dry type transformer and a power module are arranged in the power supply casing. The front side wall of the power supply casing is provided with an output voltage indicator, a running state indicator, a power switch capable of starting and shutting down discharge of the switching power supply, a manual adjustment knob, a front end heat dissipation hole and an output power indicator. The dry type transformer is adopted, and the device space is saved. A cooling fan and an internal cooling fin and the like are utilized, so that a power device can be effectively cooled, and the influence of temperature rise on the device is reduced. High voltage output terminals are isolated through a voltage-resistant insulting material, and a socket is in the high voltage protection wiring form, can be connected with a discharge module quickly and is easy to install, debug and maintain.

Description

technical field [0001] The invention relates to the fields of environmental engineering and plasma science and technology, and more specifically relates to a low-temperature plasma discharge power supply device. Background technique [0002] In recent years, low-temperature plasma technology has attracted more and more attention. Plasma is called the fourth form of matter besides solid, liquid and gas, and is composed of electrons, ions, free radicals and neutral particles. Yes, the overall electrical neutrality is maintained. Dielectric barrier discharge is a common form of discharge, which can be used in industries such as ozone generation, air purification, and surface modification. Dielectric barrier discharge, the load is a capacitive load, not a linear conversion, requiring a harsh driving power supply.

AI Technical Summary

Problems solved by technology

[0003] The existing high-voltage discharge power supply is relatively large in size, complex in installation and wiring, unstable in output, does not have protection functions such as short circuit, open circuit, overcurrent, and overvoltage, and cannot be intuitively reflected on the device. Feedback the operating status of the power supply device; cannot automatically match the load, and the energy efficiency is low; and cannot intuitively feedback the output high-voltage voltage and power; nor can it realize functions such as remote control and data recording
