Research on the Real-Time Online Measurement System for DBD Type Ozone Generator Electric Parameters

To solve the problems of time consuming, labor consuming and low efficiency in traditional geometric measurement methods, a real-time online measurement system for the electrical parameters of DBD (Dielectric Barrier Discharge) type ozone generator is designed in this paper. With this system, the accuracy and efficiency of electrical parameter measurement are greatly improved. First, the design idea of the proposed measurement system is introduced in detail from hardware circuit systems such as the controller unit circuit, signal detection circuit as well as software systems like data processing unit and result output. Second, the key points of voltage and current of DBD ozone generator at different moments are collected in real time by setting up the experiment platform of real-time online measurement system, and dielectric barrier capacitance, air gap capacitance and discharge power of DBD ozone generator are rapidly calculated. Then, based on the comparison method, the efficiency and accuracy of the main characteristic discharge parameters are verified experimentally. The experimental data show that the realtime online measurement system designed in this paper is more stable than the traditional manual calculation method, and the efficiency is improved by at least two orders magnitude. Finally, the online measurement system is briefly summarized.
