電動機作為一種拖動機械因具有結構簡單、價格低廉、使用維護方便等優點，變頻器FTB-8-7R5/11P接線方法，在國民經濟各個方面被廣泛采用。在當代，隨著電子技術的發展和智能電動機保護器技術的成熟而普及率越來越高。智能電動機保護器采用了微處理器技術，不僅解決了傳統的熱繼整定粗糙、不能實現斷相保護，重復性差、測量參數誤差大的缺點。保護器通過電流來判斷斷相故障，軟件模擬熱積累過程的方法來實現過載保護等方法保證了電機的可靠運行，而微處理器強大的擴展性包括開關量輸入、繼電器輸出，4~20mA變送輸出、RS485通訊等很好的滿足了控制系統的“四遙”功能。電動機保護器提高了電動機運行的可靠性和系統智能化要求，因此保護器的可靠運行起著舉足輕重的作用，同時也對保護器抗外界干擾提出了比較現實的要求。電動機原來接線圖中，把一次接線的A、B、C三相（交流接觸器主觸點出線側）分別穿過電動機綜合保護器的三個電流互感器孔，將電動機綜合保護器的常閉觸點接入電動機二次控制回路中（交流接觸器線圈進線端），將電動機綜合保護器的線圈和交流接觸器線圈并接即可。當電動機由于某種原因造成故障，電流增加到綜合保護器動作值時，電動機綜合保護器動作，將電動機交流接觸器斷開電源，使電動機停止運行，從而保護電動機。注意電動機綜合保護器動作值的整定，要躲過電動機的啟動電流值。 變頻器FTB-8-7R5/11P接線方法-富田電氣(推薦商家)由秦皇島富田電氣設備有限公司提供。秦皇島富田電氣設備有限公司在儀器儀表這一領域傾注了諸多的熱忱和熱情，富田電氣一直以客戶為中心、為客戶創造價值的理念、以品質、服務來贏得市場，衷心希望能與社會各界合作，共創成功，共創輝煌。相關業務歡迎垂詢，聯系人：付先生。
