既然大家对压电变压器这么感兴趣,我接着发电我们产品的测试数据

压电陶瓷变压器是一种实现电能--机械能--电能转换的新型元件.压电陶瓷变压器的工作原理是利用压电陶瓷的正和逆压电效应,它通过对压电陶瓷体的电极和极化方向取向的不同进行设计,利用逆压电效应使输入端相连接的压电陶瓷在电压作用下产生机械振动,再通过正压电效应使输出端连接的压电陶瓷产生电压.当输入和输出端的阻抗不相等时,导致它们的电压和电流也不相等,从而实现输入和输出端之间的电压和电流大小变换的功能.其主要器件压电陶瓷片是用无机非金属材料经高温烧结和高压极化等一系列工艺而制成的新型功能陶瓷材料.此类变压器与传统电磁变压器相比,具有体积小、重量轻、结构简单、不用铜铁材料、不怕受潮、不会燃烧、不受电磁干扰等优点.压电陶瓷变压器具有转换效率高、无电磁辐射、体积小、不燃烧、安全和可靠的特点.
压电陶瓷变压器的优势主要有以下几个方面: ①转换的效率很高,与传统变压器的60%至85%的效率相比,压电陶瓷变压器很容易做到98%以上; ②能量密度很大,相应体积可以做到很小,很薄; ③没有电磁干扰,由于换能的过程是由机械振动完成,并不是电磁转换; ④环境适用性强,耐低温、耐高湿、耐酸耐碱、不会霉变,寿命长; ⑤标准正弦输出,不受变压器输入波形畸变的影响;
⑥变压器输入输出之间耐压高,漏流低,一般情况下,变压器的输入输出之间在3700VDC/分下,漏流<20μA,在3000VAC/分下,漏流<200μA;
⑦变压器自身具有很好的滤波功能;
⑧变压器具有短路自动保护功能.500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/64/2504941208759704.jpg?x-oss-process=image/watermark,g_center,image_YXJ0aWNsZS9wdWJsaWMvd2F0ZXJtYXJrLnBuZz94LW9zcy1wcm9jZXNzPWltYWdlL3Jlc2l6ZSxQXzQwCg,t_20');}" onmousewheel="return imgzoom(this);">500) {this.resized=true;
