描述
變頻器的日常維護(hù)中也有一些需要特別注意的事項(xiàng),如何若發(fā)現(xiàn)變頻器故障跳停,不要像一般人處理那樣,立即打開變頻器進(jìn)行維修。這樣做是很危險(xiǎn)的,有可能發(fā)生人身觸電事故。這是因?yàn)榧词棺冾l器不處于運(yùn)行狀態(tài),甚至電源已經(jīng)切斷,由于其中的電容器的存在,變頻器的電源輸入線、直流端子和電動(dòng)機(jī)端子上仍然可能帶有電壓。其次,對(duì)變頻器的輸出參數(shù)進(jìn)行測(cè)量時(shí)也要特別注意。應(yīng)根據(jù)各控制方式的不同來(lái)不同對(duì)待
