去离子装置的电场分布及气流流动对带电粒子作用的研究

分析了强迫风冷大电流封闭母线中气体带电粒子产生的原因和其中的气体流动状况;采用有限单元法计算了平板式和圆筒式去离子装置端口处电场分布,分析了气流中带电粒子在电场的作用下的运动情况;通过在模型段上对去离子装置的测试,进一步确定了去离子装置设计的方案。

The reasons of producing electric particle of gas and the condition of air flowing in large current enclosed busbar with forced air cooling are analysed. The finite element method is used to calculate the electric-field distribution on the port of the planar and cylidrical deionization device. The movements of electric particle in airflow by the action of electric field are analysed. By the test measurement of deionization device on the model,the scheme of the deionization device is identified.
