Description

technical field [0001] The invention belongs to the field of high-voltage electrostatics, and in particular relates to a discharge system for adjusting the electrostatic voltage of high-voltage electrostatic equipment. Background technique [0002] Precise control of voltage in high voltage electrostatic applications is difficult. If there is a discharge tube whose discharge speed can be controlled in real time, combined with a non-contact high-voltage electrostatic voltage measuring instrument to discharge slowly when the voltage exceeds a predetermined value, precise control of the voltage can be realized. [0003] Chinese patent: Application number: CN201410408700.4 Patent name: A high-voltage electrostatic discharge tube (hereinafter referred to as the prior art A), which provides a method for adjusting the static voltage of the equipment. Static voltage at the output, but with the following technical defects: [0004] Technical defects 1. It has mechanical movement, w...

AI Technical Summary

Problems solved by technology

[0004] Technical defect 1. It has mechanical movement, which is easy to wear and affects the service life

[0005] Technical defect 2. When it discharges each time, the released charge is quantitative. The higher the pressure difference that needs to be adjusted, the more times the charge needs to be released. There is a technical defect of 'wasting time'

[0006] Technical defect 3. Electromagnetic conduction and magnetic conduction torsion beams lead to a reduction in the distance between the two main conductors, shortening in disguise, and the distance between the two output ends of the high-voltage electrostatic equipment is likely to cause creepage (high-voltage static electricity passes through the conductive Magnetic torsion beam pulls out the arc), the higher the static voltage, the easier the static voltage control will fail, and there is a technical defect of "easy to fail"

[0007] Technical defect 4. After a long running time, due to the wear of the torsion shaft, the ratio of the control current to the unloading speed of the charge shifts, which needs to be corrected, and there is a technical defect of 'difficult to control'

[0008] Technical defect 5. Since there are always errors in engineering products, each product entity of the prior art A needs to be carefully tested and recorded to cause the relationship curve between the control current and the charge unloading speed before it can be used. There is a 'complicated production process' ' and 'slow production speed', the two technical flaws
