無論在基礎上還是起步時間上都落后于歐美國家。但至少目前技術已經不是與國外變頻器行業(yè)的壁壘,而穩(wěn)定性及產品性能才是各個廠商面臨的主要技術問題。許多國內軟啟動企業(yè)都在變頻器研發(fā)上投入大量的人力與物力,力求在變頻器技術方面占領制高點。一批的變頻器企業(yè)脫穎而出,成為了國內上市企業(yè)。盡管如此,變頻器的核心器件IGBT和芯片始終依賴進口,成為制約變頻器國產的瓶頸。變頻器核心器件的研發(fā)制造是變頻器產業(yè)需要突破的一個重要關口,威爾凱電氣也正在這個領域進行不懈地堅持和努力。我想不久的將來,的變頻技術是有可能達到甚至超越外國先進水平,至于多久能夠實現(xiàn),我們一起拭目以待吧。全球性“節(jié)能減排”工業(yè)改造計劃正在大規(guī)模推行,作為大國也高度重視節(jié)能減排。
