荧光灯上使用无锡变频器的主要目的是调节电源供电频率

来源: 日期:2020-01-28

无锡变频器是应用非常广泛,种类型号也是多种多样,但不论是用于家庭还是用于企业和工厂的,不论是单相交流电还是三相交流电,它们的电压和频率都是大同小异的,每个国家也都有一定的规定标准。各国间的标准可能并不一样,就我国而言直接用户单相交流电压为220V,三相交流电线电压为380V,频率为50Hz,那么无锡变频器的工作原理大家清楚吗?

通常,把电(dian)(dian)(dian)压(ya)和频(pin)(pin)(pin)(pin)率(lv)(lv)固定不变(bian)(bian)(bian)的(de)(de)(de)工频(pin)(pin)(pin)(pin)交(jiao)(jiao)流(liu)电(dian)(dian)(dian)变(bian)(bian)(bian)换为(wei)(wei)电(dian)(dian)(dian)压(ya)或频(pin)(pin)(pin)(pin)率(lv)(lv)可(ke)变(bian)(bian)(bian)的(de)(de)(de)交(jiao)(jiao)流(liu)电(dian)(dian)(dian)的(de)(de)(de)装(zhuang)置(zhi)称作“变(bian)(bian)(bian)频(pin)(pin)(pin)(pin)器(qi)”。为(wei)(wei)了产生可(ke)变(bian)(bian)(bian)的(de)(de)(de)电(dian)(dian)(dian)压(ya)和频(pin)(pin)(pin)(pin)率(lv)(lv),该设备首先要(yao)把电(dian)(dian)(dian)源的(de)(de)(de)交(jiao)(jiao)流(liu)电(dian)(dian)(dian)变(bian)(bian)(bian)换为(wei)(wei)直流(liu)电(dian)(dian)(dian)(DC),这(zhei)个过程叫整流(liu)。一(yi)般(ban)逆(ni)(ni)变(bian)(bian)(bian)器(qi)是把直流(liu)电(dian)(dian)(dian)源逆(ni)(ni)变(bian)(bian)(bian)为(wei)(wei)一(yi)定频(pin)(pin)(pin)(pin)率(lv)(lv)和一(yi)定电(dian)(dian)(dian)压(ya)的(de)(de)(de)逆(ni)(ni)变(bian)(bian)(bian)电(dian)(dian)(dian)源。对(dui)于逆(ni)(ni)变(bian)(bian)(bian)电(dian)(dian)(dian)源频(pin)(pin)(pin)(pin)率(lv)(lv)和电(dian)(dian)(dian)压(ya)可(ke)调的(de)(de)(de)逆(ni)(ni)变(bian)(bian)(bian)器(qi)我们称为(wei)(wei)变(bian)(bian)(bian)频(pin)(pin)(pin)(pin)器(qi)。

变(bian)频(pin)器(qi)输出的(de)(de)(de)波(bo)(bo)形是(shi)模拟正弦(xian)波(bo)(bo),主要(yao)是(shi)用在三相异步电(dian)(dian)动机调(diao)速用,又叫变(bian)频(pin)调(diao)速器(qi)。对于主要(yao)用在仪器(qi)仪表的(de)(de)(de)检测设备中的(de)(de)(de)波(bo)(bo)形要(yao)求(qiu)较高(gao)的(de)(de)(de)可变(bian)频(pin)率逆变(bian)器(qi),要(yao)对波(bo)(bo)形进行(xing)整理(li),可以输出标(biao)准的(de)(de)(de)正弦(xian)波(bo)(bo),叫变(bian)频(pin)电(dian)(dian)源。一般变(bian)频(pin)电(dian)(dian)源是(shi)变(bian)频(pin)器(qi)价格(ge)的(de)(de)(de)15--20倍。

变(bian)(bian)(bian)频(pin)(pin)(pin)器(qi)(qi)也可(ke)用(yong)(yong)于(yu)(yu)(yu)(yu)家电(dian)(dian)产(chan)品(pin)。使用(yong)(yong)变(bian)(bian)(bian)频(pin)(pin)(pin)器(qi)(qi)的(de)家电(dian)(dian)产(chan)品(pin)中,不仅有(you)电(dian)(dian)机(ji)(ji)(例(li)如空调等),还有(you)荧光灯(deng)(deng)等产(chan)品(pin)。用(yong)(yong)于(yu)(yu)(yu)(yu)电(dian)(dian)机(ji)(ji)控制的(de)变(bian)(bian)(bian)频(pin)(pin)(pin)器(qi)(qi),既可(ke)以(yi)改变(bian)(bian)(bian)电(dian)(dian)压,又可(ke)以(yi)改变(bian)(bian)(bian)频(pin)(pin)(pin)率。但用(yong)(yong)于(yu)(yu)(yu)(yu)荧光灯(deng)(deng)的(de)变(bian)(bian)(bian)频(pin)(pin)(pin)器(qi)(qi)主要用(yong)(yong)于(yu)(yu)(yu)(yu)调节电(dian)(dian)源供电(dian)(dian)的(de)频(pin)(pin)(pin)率。变(bian)(bian)(bian)频(pin)(pin)(pin)器(qi)(qi)的(de)工作原理(li)被广(guang)泛应用(yong)(yong)于(yu)(yu)(yu)(yu)各个领域(yu)。例(li)如计算机(ji)(ji)电(dian)(dian)源的(de)供电(dian)(dian),在该(gai)项(xiang)应用(yong)(yong)中,变(bian)(bian)(bian)频(pin)(pin)(pin)器(qi)(qi)用(yong)(yong)于(yu)(yu)(yu)(yu)抑(yi)制反向电(dian)(dian)压、频(pin)(pin)(pin)率的(de)波动及电(dian)(dian)源的(de)瞬间断电(dian)(dian)。

无锡变频器

变(bian)频器主要采用(yong)交(jiao)(jiao)—直(zhi)—交(jiao)(jiao)方式(shi)(VVVF变(bian)频或矢量控制变(bian)频),先把(ba)工频交(jiao)(jiao)流(liu)(liu)电(dian)源通过整流(liu)(liu)器转换成直(zhi)流(liu)(liu)电(dian)源,然后再(zai)将直(zhi)流(liu)(liu)电(dian)

源(yuan)转(zhuan)换成(cheng)频率、电压均可控制的(de)交(jiao)流电源(yuan)以供给电动(dong)(dong)机。变(bian)频器主要由整(zheng)流(交(jiao)流变(bian)直(zhi)流)、滤(lv)波、逆变(bian)(直(zhi)流变(bian)交(jiao)流)、制动(dong)(dong)单(dan)(dan)元(yuan)(yuan)、驱动(dong)(dong)单(dan)(dan)元(yuan)(yuan)、检测(ce)单(dan)(dan)元(yuan)(yuan)微处理单(dan)(dan)元(yuan)(yuan)等组成(cheng)的(de)。

其实变频器的工作原理被广泛应用于各个领域,较为常见的是我们经常使用的计算机,计算机的电源供电中变频器用于抑制反向电压、频率波动及电源的瞬间断电等;还有我们家庭中的一些用品,像是空调、荧光灯等都有用到变频器。如果大家想对无锡变频器进行详细了解,可咨询无锡市科德科技有限公司,我们是一家经验丰富的从事三垦变频器的销售、设计及售后服务的企业。
