<div class="kmtxt">1 环境温度降额
当逆变单元在+40℃~+50℃的环境温度下工作时，环境温度每增加 1℃，额定输出电流须降额 1%，将产品额定值表中的电流给定值乘以降额系数（ke），即可得出此温度下输出电流。
 2 海拔高度降额
逆变单元在海拔 1000m 以上工作时需降额使用，海拔每升高 100m 降额 1%，当工作环境海拔超过 2000m 时，请

原理：漏电保护开关检测的是输入共模电流，正常情况下，零序电流为零。但变频器输出侧为 PWM 波，电机电缆与大地之间存在长电缆的电容效应，使用带屏蔽层的电缆时，电容效应更明显。在变频器工作时，电容充放电产生电流，该电流通过电容流入大地，并从进线侧的接地线再流回变频器，形成电流回路，导致漏电保护 ...</div>
