济南变频器维修时零部件的更换

浏览量:   来源:www.bcabb.com  作者:宝川

济南变频器故障常常拆换的零配件关键有散热器风扇和滤波电容,实际的缘故大家一起来认识一下吧


Jinan frequency converter failure often dismantled parts of the key radiator fan and filter capacitor, the actual reason for everyone to know it together


散热器风扇是通用变频器的输出功率控制模块是发烫最比较严重的元器件,其持续工作中所造成的发热量务必要立即排出来,通常电扇的使用寿命大概为10Kh—40Kh。


Radiator fan is the output power control module of general frequency converter, which is the most serious component. The heat generated by continuous work must be discharged immediately. Usually, the service life of the fan is about 10 Kh-40 Kh.


按通用变频器连续运行折算为2—3年就要更换一次风扇,直接冷却风扇有二线和三线之分,二线风扇其中一线为正极,另一线为负极,更换时不要接错。


Converted to 2-3 years of continuous operation of general frequency converter, the primary fan should be replaced. The direct cooling fan can be divided into two or three lines. One line of the second-line fan is positive, the other line is negative. Do not make any mistake when replacing the second-line fan.


四线电扇除开正、负级外也有一条检测线,拆换时干万留意,不然会造成通用变频器超温警报。沟通交流电扇通常为220V、380V之分,拆换时额定电压不必弄错。


Four-wire fans have a detection line besides positive and negative stages. Be careful when they are dismantled, or they will cause overtemperature alarm of universal frequency converter. Communication AC fans are usually divided into 220 V and 380 V. There is no need to make mistakes in the rated voltage when they are dismantled.


滤波电容又称电解电容,其主要作用就是平滑直流电压,吸收直流中的低频谐波,它的连续工作产生的热量加上通用变频器本身产生的热量都会加快其电解液的干涸,直接影响其容量的大小。


The filter capacitor is also called electrolytic capacitor. Its main function is to smooth DC voltage and absorb low-frequency harmonics in DC. The heat generated by its continuous operation and the heat generated by the universal frequency converter itself will accelerate the drying up of its electrolyte, which directly affects its capacity.


通常情况下电容器的使用期为5年。提议历年定期维护电容器容积一回,通常其容积降低20%左右应拆换。


Usually the life of the capacitor is five years. It is proposed that the capacitor volume be maintained periodically over the years. Usually, the capacitor volume should be replaced when it is reduced by about 20%.http://www.bcabb.com
