    电梯变频器的保养方法

    关于电梯变频器日常的保养:现在电梯都是用变频器来控制,当变频器出故障就会给很多人带来不便,也会急坏管理人员,如果平时有对变频器进行保养,则可大大降低变频器的故障率,我们在维修大量电梯变频器后,总结出平时保养的几个要注意的问题:

    1、电梯电气室温度不能太高,否则变频器元件容易老化,装有空调,效果相当不错!

    2、防止雨水淋湿,通常是在刮台风时,窗门被风吹坏而使变频器淋到雨水。

    3、防雷电,这个就关系到整栋楼或整个小区防雷设施问题,被雷击的变频器一般损坏严重。

    4、变频器的散热风扇要定时清尘,发现其有响声或不运转就要更换。

    5、电梯电机有不正常响声通常是变频器有问题,如电机三相电流不平衡,这时就要维修,等到变频器不行则损坏可能比较严重。

    6、如果自己没有维修经验就不要自己维修,要请专业维修人员修理。自己瞎弄会把变频器弄得更坏

    About the daily maintenance of elevator frequency converter: now the elevator is controlled by frequency converter. When the frequency converter breaks down, it will bring inconvenience to many people and break down the management personnel. If the frequency converter is maintained at ordinary times, the failure rate of frequency converter can be greatly reduced. After the maintenance of a large number of elevator frequency converter, we summarize several problems that should be paid attention to at ordinary times:

    1. The temperature of the elevator electrical room should not be too high, otherwise, the inverter components are easy to age, equipped with air conditioning, and the effect is quite good!

    2. Prevent the rain from getting wet. Usually, when the typhoon blows, the windows and doors are damaged by the wind, which causes the inverter to get rain.

    3. Lightning protection, which is related to the lightning protection facilities of the whole building or the whole community. Generally, the frequency converter hit by lightning is seriously damaged.

    4. The cooling fan of the frequency converter shall be cleaned regularly, and it shall be replaced if it is found to be noisy or not running.

    5. The abnormal noise of elevator motor is usually caused by the problem of frequency converter. If the three-phase current of the motor is unbalanced, it needs to be repaired. If the frequency converter fails, the damage may be serious.

    6. If you don't have maintenance experience, don't repair by yourself. Ask professional maintenance personnel to repair. If you do it yourself, you will make the inverter worse.
