避免或减少过载运行,营造好的散热环境等。然而我们发现,采用上述措施后,过热事故虽有所减少,但还未达到人们所期望的要求。笔者几年来跟踪数十例变压器过热事故,在排除安装工艺、过负荷等因素后发现,几乎每例过热事故都出现了导电杆和引出线间的连接螺丝回松(松动)现象。究其原因是:变压器用软连接(电缆,铜、铝绞线等)作引出线时,拉(压)、风、操作(如装拆接地线)及短路、冲击负荷等应力作用到连接螺丝上引起螺丝回松。
R32不能和空气混合,一定要抽真空,以免发生事故,我们也多次强调。而R41A变频空调要抽真空,主要有以下2点原因:R41A是近共沸制冷剂,是两种制冷剂(R32与R125(5%:5%wt))按照1:1混合而成的,处于气态时比例就会改变。原因很简单,因为两种的沸点不同,一种已经气化,另一种还没有。所以不能使用外气排空法,因为外气排空法将改变冷媒比例。R41A压缩机使用醚油润滑。
