LENZE变频器常见故障及解决方法

创建日期:2024-8-30 12:03:23 |来源: Lenze/Lenz

01脉冲变压器损坏

对于早期的比如8100系列、8300系列变频器,我们比较常见的故障就是开关电源的损坏,大部分都是脉冲变压器的损坏,体现出来的现象就是通电之后机器没反应,控制端无电压。因为脉冲变压器的骨架不容易拆卸,给变压器的维修造成了一定的困难,而且各个变频器品牌使用的脉冲变压器的参数都不相同,也给我们的绕线带来了一定的困难。由于此类机器市场比较小,所以我们就不详细讨论了。02

OC故障

OC5故障应该是我们在8220/8240系列变频器中经常遇到的故障现象。OC5就是变频器的过载,过载的检测一般都是通过霍尔传感器来完成的,它检测UV两相的电流,然后通过两个输入端或者门极COMOS电路来判断变频器是否过载。 OC5的故障点一般是传感器损坏和门电路损坏引起的,霍尔传感器容易受环境影响,出现工作点漂移,门电路经常会因为工作电压和输入信号的影响而损坏。更换一个损坏的器件应该可以排除此类故障。

03输出缺相

输出缺相也是我们经常遇到的故障之一。我们都知道在缺相的状态下是无法拖动三相交流异步电机的,在拖动电机的情况下会出现过流报警,而且断开电机后测量3相输出电压,3相输出电压往往是相对不同的,此时首先要检查功率模块是否损坏,驱动波形是否正常。在LENZE 8240系列变频器中,经常会遇到驱动电路没有电压的现象。 8240系列变频器与其他变频器的区别在于驱动电源不是由开关电源直接供电的,驱动电路和开关电源之间有隔离。所以我们还要检查隔离变压器是否有问题。排除上述故障要确定给驱动电路供电是否正常。04

开关电源故障

在8200系列通用变频器的维修中,我们会经常碰到开关电源的损坏,主要故障点有功率开关管的损坏和开关电源控制电路的损坏。开关管的损坏比较容易更换,原型号的三极管及其替换三极管都可以买到,控制电路发生故障后的维修相对复杂,该类型机的控制电路元器件都集成在绝缘陶瓷片上,不易更换,需要一定的经验和维修技巧。05

变频器散热引起的故障

散热器分离散热技术也是LENNZE变频器的一大卖点,我们都知道常规变频器都有散热风扇来散热,但是在某些场合散热风扇的使用往往会成为变频器常见的故障点。这种现象主要常见于纺织厂,纺织厂空气中的棉絮、化纤等往往会堵塞风扇,引起变频器故障报警。 LENZE变频器的散热器分离散热技术解决了这个问题。但是我们也会遇到使用一段时间后无法承受重负载的客户,从我们的经验分析,也可能是变频器的散热问题导致的,由于散热不足,元器件更容易老化,损耗也比较快。这种情况,更换老化的器件就可以解决问题。

另外,在实际应用中,我们还可以根据变频器发光二极管的状态来判断变频器的状态和故障,特别是在没有面板的情况下,一般绿灯亮,红灯灭,是控制面板运行状态,如果绿灯闪烁,红灯亮,就是控制面板禁用,绿灯灭,红灯每秒闪一次,变频器处于故障状态。
