<p><a href="http://www.chenfeipower.com/"><strong>高频变压?/strong></a>拉弧是指电压超过空气的耐受力使空气电离变成导体也就是产生电?电弧一般会绕过绝缘体沿着绝缘体的表面产生 因而会对绝缘体产生损坏 如电弧的高温会使绝缘体融化或碎裂。辟如开关上表明额定短路开断电?0KA,表示20KA内的短路跳闸触头灭弧热元件动作等有效，超过这个绝限跳闸接头灭弧热元件动作不保证，会产?拉弧?<br />
</p>
<p><br />
一般高频变压器打火拉弧但是还能正常工作,就要去测试ARCING.但是如果不能正常工作,那就要去测HI-POT(可能是线圈对线圈打火短路,或者是线圈对磁芯打火短?. 正常情况下在高频变压器的生产过程中HI-POT和ARCING都是必须要测试的.<br />
</p>
<p><br />
HI-POT测试主要是测试变压器是否损坏和变压器能否达到额定的耐压需?而ARCING测试是专门针对电弧放电进行的测试,是为了检测出变压器任何地方存在电弧放电现?避免因为电弧放电导致变压器的寿命缩短.一般高频变压器ARCING测试的等级都设定?,也就?.5mA.<br />
<br />
以上就是为大家介绍的有关高频变压器打火拉弧应该如何处理的问题分析，希望能够帮到大家?br />
