濟(jì)南變頻器故障常常拆換的零配件關(guān)鍵有散熱器風(fēng)扇和濾波電容，實(shí)際的緣故大家一起來認(rèn)識(shí)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
散熱器風(fēng)扇是通用變頻器的輸出功率控制模塊是發(fā)燙比較嚴(yán)重的元器件，其持續(xù)工作中所造成的發(fā)熱量務(wù)必要立即排出來，通常電扇的使用壽命大概為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.
按通用變頻器連續(xù)運(yùn)行折算為2—3年就要更換一次風(fēng)扇，直接冷卻風(fēng)扇有二線和三線之分，二線風(fēng)扇其中一線為正ji，另一線為負(fù)ji，更換時(shí)不要接錯(cuò)。
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.
四線電扇除開正、負(fù)級(jí)外也有一條檢測線，拆換時(shí)干萬留意，不然會(huì)造成通用變頻器超溫警報(bào)。溝通交流電扇通常為220V、380V之分，拆換時(shí)額定電壓不必弄錯(cuò)。
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.
濾波電容又稱電解電容，其主要作用就是平滑直流電壓，吸收直流中的低頻諧波，它的連續(xù)工作產(chǎn)生的熱量加上通用變頻器本身產(chǎn)生的熱量都會(huì)加快其電解液的干涸，直接影響其容量的大小。
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.
通常情況下電容器的使用期為5年。提議歷年定期維護(hù)電容器容積一回，通常其容積降低百分之20左右應(yīng)拆換。
