工控自動(dòng)化產(chǎn)品變頻器本身產(chǎn)生了節(jié)能省電是一種錯(cuò)誤的認(rèn)識(shí)。變頻器是否能夠達(dá)到省電、節(jié)能的效果,還需要根據(jù)所使用的實(shí)際情況而定。
在很多資料或文獻(xiàn)中,工控自動(dòng)化產(chǎn)品變頻器都被描述成為節(jié)電、節(jié)能的控制自動(dòng)化產(chǎn)品,因此,很多人都會(huì)認(rèn)為,只要設(shè)備裝上變頻器就一定能節(jié)能省電,其實(shí)并不是這樣的。工控自動(dòng)化產(chǎn)品變頻器本身產(chǎn)生了節(jié)能省電是一種錯(cuò)誤的認(rèn)識(shí)。變頻器是否能夠達(dá)到省電、節(jié)能的效果,還需要根據(jù)所使用的實(shí)際情況而定。
誤區(qū)一、很多人都認(rèn)為兩個(gè)電機(jī)的扭矩沒有達(dá)到電機(jī)的額定扭矩狀態(tài)下工作(頻率,轉(zhuǎn)速還是一樣50HZ),變頻器也會(huì)起到節(jié)能省電的作用,這是一種錯(cuò)誤的認(rèn)為。
誤區(qū)二、兩個(gè)一模一樣的電機(jī)都工作在50HZ的工頻狀態(tài)下,一個(gè)使用變頻器,一個(gè)沒有,同時(shí)轉(zhuǎn)速和扭矩都在電機(jī)的額定狀態(tài)下,相信大多數(shù)人都會(huì)認(rèn)為哪個(gè)使用變頻器的電機(jī)會(huì)比較節(jié)能省電。其實(shí)這也是一種錯(cuò)誤的想法。
誤區(qū)三、同樣的條件,很多人都認(rèn)為空載狀態(tài)下能省能省下很多電,但其實(shí)拖動(dòng)型負(fù)載空載狀態(tài)也節(jié)省不了多大的電能。
變頻器之所以在大部分的情況下能夠達(dá)到節(jié)電、節(jié)能的效果、其原因在于變頻器對(duì)電機(jī)進(jìn)行了調(diào)速控制,但實(shí)際上,大部分的調(diào)速設(shè)備都可以達(dá)到這一效果,因?yàn)楹苊黠@我們并不能因此而認(rèn)定變頻器就是一種節(jié)能型產(chǎn)品。
26) 每個(gè)人都是他人生的主角,可是一旦淪為配角,就是他傷心的時(shí)候。
