變頻器是快速卷簾門產(chan)品(pin)安(an)裝和使用時必不可少的(de)一大配件(jian)，它(ta)通過(guo)變(bian)頻(pin)調換來實現快(kuai)速開(kai)啟、關(guan)閉的(de)效果，對(dui)于滿足(zu)快(kuai)速卷簾門日常運行的(de)輔助作用十(shi)分(fen)重(zhong)要。對(dui)于變(bian)頻(pin)器，真(zhen)正了解(jie)的(de)人并不多，因此蘇州快(kuai)速卷簾門廠家襄陽理想門業就來給(gei)大家介紹下變(bian)頻(pin)器的(de)有(you)關(guan)知識。

　　所謂的(de)(de)(de)快速(su)卷簾門變(bian)(bian)頻(pin)(pin)器是(shi)把(ba)工(gong)頻(pin)(pin)電(dian)(dian)源(yuan)(50Hz或60Hz)變(bian)(bian)換成各種頻(pin)(pin)率(lv)的(de)(de)(de)交(jiao)流(liu)電(dian)(dian)源(yuan)，以實現電(dian)(dian)機的(de)(de)(de)變(bian)(bian)速(su)運(yun)行(xing)(xing)的(de)(de)(de)設備，其中控(kong)(kong)制電(dian)(dian)路(lu)完成對(dui)主電(dian)(dian)路(lu)的(de)(de)(de)控(kong)(kong)制，整流(liu)電(dian)(dian)路(lu)將交(jiao)流(liu)電(dian)(dian)變(bian)(bian)換成直流(liu)電(dian)(dian)，直流(liu)中間(jian)電(dian)(dian)路(lu)對(dui)整流(liu)電(dian)(dian)路(lu)的(de)(de)(de)輸出進行(xing)(xing)平(ping)滑(hua)濾波，逆變(bian)(bian)電(dian)(dian)路(lu)將直流(liu)電(dian)(dian)再(zai)逆流(liu)電(dian)(dian)。而對(dui)于如矢(shi)量(liang)控(kong)(kong)制變(bian)(bian)頻(pin)(pin)器這種需要大量(liang)運(yun)算(suan)(suan)的(de)(de)(de)變(bian)(bian)頻(pin)(pin)器來說，有(you)時(shi)還需要一個進行(xing)(xing)轉矩計算(suan)(suan)的(de)(de)(de)CPU以及一些相應的(de)(de)(de)電(dian)(dian)路(lu)。一句話(hua)來說，就是(shi)變(bian)(bian)頻(pin)(pin)調速(su)是(shi)通過(guo)改變(bian)(bian)電(dian)(dian)機定子繞組(zu)供電(dian)(dian)的(de)(de)(de)頻(pin)(pin)率(lv)來達到調速(su)的(de)(de)(de)目的(de)(de)(de)。

　　快速(su)卷簾門所(suo)用的(de)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)有多種分(fen)類(lei)(lei)方(fang)法，其(qi)中按(an)(an)照(zhao)主電路工作方(fang)式分(fen)類(lei)(lei)，可(ke)(ke)以(yi)分(fen)為(wei)(wei)電壓型(xing)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)和(he)電流型(xing)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi);按(an)(an)照(zhao)開關方(fang)式分(fen)類(lei)(lei)，可(ke)(ke)以(yi)分(fen)為(wei)(wei)PAM控(kong)(kong)制變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)、PWM控(kong)(kong)制變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)和(he)高(gao)載頻(pin)(pin)PWM控(kong)(kong)制變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi);按(an)(an)照(zhao)工作原理分(fen)類(lei)(lei)，可(ke)(ke)以(yi)分(fen)為(wei)(wei)V/f控(kong)(kong)制變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)、轉(zhuan)差頻(pin)(pin)率控(kong)(kong)制變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)和(he)矢量控(kong)(kong)制變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)等;按(an)(an)照(zhao)用途分(fen)類(lei)(lei)，可(ke)(ke)以(yi)分(fen)為(wei)(wei)通(tong)用變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)、高(gao)性能專用變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)、高(gao)頻(pin)(pin)變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)、單(dan)相變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)和(he)三相變(bian)(bian)(bian)頻(pin)(pin)器(qi)(qi)(qi)等等。

　　而目(mu)前各國使(shi)用(yong)的交流供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)，無論是用(yong)于家庭還是用(yong)于工廠，其電(dian)(dian)(dian)(dian)壓和頻(pin)率(lv)(lv)均為400V/50Hz或200V/60Hz(50Hz)等。我們通常(chang)把電(dian)(dian)(dian)(dian)壓和頻(pin)率(lv)(lv)固定不(bu)變的交流電(dian)(dian)(dian)(dian)變換(huan)為電(dian)(dian)(dian)(dian)壓或頻(pin)率(lv)(lv)可(ke)(ke)變的交流電(dian)(dian)(dian)(dian)的裝置(zhi)稱作“變頻(pin)器(qi)(qi)”。為了(le)產(chan)生(sheng)可(ke)(ke)變的電(dian)(dian)(dian)(dian)壓和頻(pin)率(lv)(lv)，該設備首先要把電(dian)(dian)(dian)(dian)源(yuan)的交流電(dian)(dian)(dian)(dian)變換(huan)為直流電(dian)(dian)(dian)(dian)(DC)。而用(yong)于電(dian)(dian)(dian)(dian)機控制的變頻(pin)器(qi)(qi)，既可(ke)(ke)以(yi)改(gai)變電(dian)(dian)(dian)(dian)壓，又可(ke)(ke)以(yi)改(gai)變頻(pin)率(lv)(lv)，如此才能滿足快速(su)卷簾門(men)高(gao)速(su)運行的需要。
