A 3P220V US counter machine. Before the external machine heat sink leakage of fluoride. Check the repair later. Use about two weeks, the external machine AC contactor coil burned, with CJX2-2510, three groups in parallel instead. And use 2 weeks or so, the effect has been good. Now suddenly start a minute or two later. Power trip. And the compressor heat protection. Checked. The size of the external capacitor is normal. Outside the heat sink is also clean. Inside the fan is also normal. Unplug the compressor line. Will not trip. So the question is coming. Now measure the three resistance of the compressor line 1.7 1.8 3.2 and start (and after the operation) current up to 30 or more. Run for a couple of minutes on heat and the power trip. Let go of some fluoride. Start running low voltage 0.35 after ten seconds to increase to 0.5 minutes after a minute or trip and hot burst. Ask you a great God diagnosis
一台3P220V的美的柜机。以前外机散热片漏氟。检查维修好了以后。使用两周左右，外机交流接触器线圈烧毁，用CJX2-2510，三组并联代替。又使用2周左右，效果一直不错。现在突然开机一两分钟后。电源跳闸。并且压缩机热保。经检查。外机大小电容正常。外散热片也干净。内机风扇也正常。拔掉压缩机线。不会跳闸。那么问题来了。现在测量压缩机三根线阻值1.7 1.8 3.2 并且启动（且运转后）电流高达30多安。运转一两分钟就热保并且电源跳闸。放掉部分氟以后。开机运转低压0.35十几秒后增加到0.5.一分钟左右后，还是跳闸并且热爆。请教各位大神诊断
排除掉压机连接线接触不良，那么只剩压机扎间短路了
