MVME147-013嚴(yán)重惡劣環(huán)境下的對策
有的環(huán)境十分惡劣,既有高溫還有腐蝕性氣體、灰塵、潮氣等,變頻器極易發(fā)生故障。
1)對策如同油浸變壓器一樣,對變頻器進(jìn)行全密封強(qiáng)迫循環(huán)冷卻,具體辦法如下。
(1)做一密閉容器,容器上安裝好變頻器的三相輸入/輸出、外接制動電阻、引出控制的接線柱,變頻器內(nèi)置,若有制動單元則制動單元也內(nèi)置;容器上下兩側(cè)有進(jìn)油孔和出油孔,油泵強(qiáng)迫油循環(huán),油在外部進(jìn)行交換散熱。

(2)對變頻器內(nèi)部的元器件涂刷圓耀猿遍絕緣漆以保證變頻器浸入油中時其元器件同油相隔離。
(3)冷卻介質(zhì)為變壓器油。
(4)變頻器的發(fā)熱器件應(yīng)盡量在油路通道上。
(5)拆除原散熱風(fēng)機(jī)。
