【摘要】 针对静电复印机高压电源中升压电磁变压器线匝之间易打火、击穿、故障率高问题 ,采用 PMMN陶瓷材料制备出片式结构的压电陶瓷变压器 ,又以压电陶瓷变压器为升压器件研制出符合静电复印机技术要求的压电陶瓷变压器高压电源 ,从根本上解决了传统高压电源存在的问题 ,这种电源还具有体积小、质量轻、不怕短路、工作效率高等特点更多还原

【Abstract】 Focused on the problems of high fault ratio and frequently appeared arcing between electromagnetic loops of high voltage power in copyflo,one kind of long shaped piezoelectric ceramic transformer was fabricated with a modified PMMN piezoelectric ceramic material A high voltage power was made with this transformer as voltage riser This power was applied to copyflo and resolved the problems of traditional high voltage power At the same time,this kind of high voltage power has such advantages as small size?light?high efficiency and no deterioration while in short cut更多还原
