加濕器的電氣連接一定需要專(zhuān)業(yè)人員操作嗎?
加濕器的電氣連接需要由具有資格的專(zhuān)業(yè)人員執行
Theelectricalconnectionofthehumidifierneedstobecarriedoutbyqualifiedprofessionals.
機組使用的電源應由專(zhuān)線(xiàn)提供作業(yè),機組提供了完整的內部電路,電路的安裝及配置均按照設備銘牌中所標定的電壓及頻率;機器不可在超過(guò)制造范圍的電壓及頻率下進(jìn)行操作。

機組總電源進(jìn)線(xiàn)為五色電纜,接入機組電器柜的相應接線(xiàn)端子排上;在連接機組總電源進(jìn)線(xiàn)時(shí),需要注意五色電纜中線(xiàn)直徑較細的芯線(xiàn)接三相電源中線(xiàn),黃綠線(xiàn)接地,其余三根線(xiàn)接電源。

在機組接通主電源前,應對三相交流供電進(jìn)行檢查,以確保所供電壓波動(dòng)范圍不超過(guò)設備表明電壓及頻率的10%,對于高負荷場(chǎng)合能夠引起電壓的波動(dòng),此項檢查尤為重要;機組必須接地,且設置帶熔斷器的空氣開(kāi)關(guān)以保證設備在檢查和服務(wù)時(shí)與電源絕緣。

熔斷器的熔斷功率必須與所安裝機組的型號及類(lèi)型相一致。熔斷器應該安裝在容易觸及的機組控制板上;電纜尺寸及熔斷功率,供電電纜及主電熔器對于所安裝的機組來(lái)說(shuō)必須有對應正確的尺寸及熔斷功率,細節參見(jiàn)附后的電氣資料;機組的電源進(jìn)線(xiàn)上需要增加火警斷電保護以便及時(shí)發(fā)現問(wèn)題、減少不必要的麻煩。
