<p>为了保证变压器(或电抗器)能正常运行需定期检查和维护,一般在干燥清洁的场所,每年进行一次检查,在其它场合,如可能有灰尘或化学烟雾污染空气进入时,每3-6个月进行一次检查。检查变压器(电抗器?各部位(铁心与线圈之间风道内、铁心及线圈本体上、变压器柜体内部等)有无异物,紧固件是否松动,紧固件松动的须拧紧。在紧固过程中,为防止变压器(电抗器)引线及线鼻子受损或折断,应避免引线及线鼻子转动。如运行过程中产生积灰,请用干燥的压缩空气清除?/p> <p>变压器(电抗器)退出运行后,一般不需要采取其它措施即可重新投入运行。若在高湿度下已发生凝露现象,必须经过干燥处理后才能重新投入运行?/p> <!-- InstanceEndEditable --></div> </div> <span class="clear"></span> <div id="bottom"> <div id="bottom-1k"> <div
