Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a plasma generating device. Background technique [0002] Plasma is the fourth form of matter besides gas, liquid, and solid. It was first proposed by British physicist and chemist W. Crookes in 1879. The generation of plasma requires driving energy, which can be in the form of electricity, magnetism, light, heat, etc., and gas discharge under high voltage is the most commonly used plasma generation method, and the applied voltage waveform may be DC, AC, pulse or coupled and other forms. Under the complex electromagnetic field, the components of the plasma generating device will also produce conductance loss, polarization loss, induction loss, etc., resulting in deterioration or damage to the insulation of the device, and the plasma generating device may need to work continuously for a long time, and the working environment may be high temperature, High humidity, complex compon...

Under the complex electromagnetic field, the components of the plasma generating device will also produce conductance loss, polarization loss, induction loss, etc., resulting in deterioration or damage to the insulation of the device, and the plasma generating device may need to work continuously for a long time, and the working environment may be high temperature, High humidity, complex components, etc., the electrical insulation performance is the key to the safety and reliability of the plasma generator, therefore, it is very important to enhance the electrical insulation performance of the plasma generator

[0003] One of the main problems faced by the existing high-voltage discharge plasma generating device is insufficient insulation performance. During long-term operation or under harsh working environment, the plasma generating device is prone to partial discharge, which leads to deterioration or damage of the insulating material. Discharge or volume breakdown failure, resulting in damage to the plasma generating device

The existing technology often adopts methods such as increasing the size of insulating materials or replacing expensive high-performance insulating materials to reduce the probability of device damage, so it also has the disadvantage of poor economy
