江西快3In order to ensure the normal and reliable operation of the inverters, it is necessary to cool the inverters.

YINGDUIBIANPINQIFAREDEZHUYAOFANGFAYOU:

The main ways to deal with the fever of the frequency converter are as follows:

(1)FENGSHANSANRE:BIANPINQINEIBUFENGSHANKEYIDAIZOUBIANPINQIXIANGNEIDESANRE。

(1) Fan heat dissipation: the fan inside the converter can take away the heat dissipation in the converter box.

(2)HUANJINGWENDU:NIBIANQISHIYIZHONGDIANZISHEBEI,BAOHANDIANJIEDIANRONGDENGDIANZIYUANJIAN,YINCIWENDUDUIQISHOUMINGYOUJIAODAYINGXIANG。YIBANBIANPINQIDEHUANJINGGONGZUOWENDUYIBANYAOQIUWEI-10℃ ~+50℃,RUGUONENGJIANGDIBIANPINQIDEGONGZUOWENDU,BIANPINQIDESHIYONGSHOUMINGJIANGHUIYANZHANG,XINGNENGJIANGHUIWENDING。WOMENYIZHIMANGYUNIBIANQIDEWEIHU。(1)KEYIYANZHANGBIANPINQIDESHIYONGSHOUMING(2)ZAIDIANQIFANGMIAN,KEYISHUOJIANGDILEWEIXIULV(3)YEKEYIFANYINGGONGSIDEGUANLIHEXINGXIANG!

Generally, the ambient working temperature of frequency converter is - 10 +50. If the working temperature of frequency converter can be reduced, the service life of frequency converter will be prolonged and its performance will be stable. We have been busy with the maintenance of inverters. (1) Can extend the life of the converter (2) In the electrical field, it can be said that the maintenance rate (3) can also reflect the company's management and image!

1. Frequency converter must be disintegrated to see if there are any abnormal phenomena inside. (e.g. loosening of upsetting wire, solder peeling off, device loosening, device burning, burning phenomenon.)

2、 JIANCHABIANPINQINEIBUYILAOHUAQIJIAN,RU:FENGSHAN,GONGLVQIJIAN,GONGLVDIANRONG,JIYINBANLAOHUAXIANXIANG。

A new imported electronic cleaner is used for spray cleaning to remove the aging layer and conductive substances.
