变频器的选型以及变频器应用注意的问题是什么

发布日期:2019-01-03 作者: 点击:

在日常工作当中,变频器选型时应该要注意哪些事项呢?首先我们要知道变频器不是在任何情况下都能正常使用,因此用户有必要对负载、环境要求和变频器有更多了解。变频器厂

(3)在输入侧装交流电抗器或EMC波器根据变频器安装场所的其他设备对电网品质的要求,若变频器工作时已影响到这些设备的正常运行,可在变频器输入侧装交流电抗器或EMC滤波器,抑制由功率器件通断引起的电磁十扰。若与变频器连接的电网的变压器中性点不接地.则不能选用EMC滤波器当变频器用500v以上电压驭动电机时,需在输出侧配置du/dt滤波器,以抑制逆变输出电压尖峰和电压的变化.有利于保护电机,同时.也降低了容性漏电流和电机电缆的高频辐射以及电机的高频损耗和轴承电流。使用du/dt滤波器时要注意滤波器土的电压降将引起电机转矩的稍微降低:变频器与滤波器之间电缆长度不得超过3m。变频器厂
