(1)電力電子設備
電(dian)(dian)力電(dian)(dian)子設備主要包括整(zheng)(zheng)流(liu)器、變頻(pin)器、開關(guan)電(dian)(dian)源、靜態換流(liu)器、晶閘管系統(tong)及其他SCR控(kong)制(zhi)系統(tong)等。由于工(gong)業與(yu)民用(yong)電(dian)(dian)力設備常用(yong)到這類(lei)電(dian)(dian)力電(dian)(dian)子設備和(he)電(dian)(dian)路,如整(zheng)(zheng)新和(he)變領(ling)電(dian)(dian)路,其負載性(xing)質(zhi)一(yi)般分為感(gan)性(xing)和(he)容(rong)(rong)性(xing)兩種,感(gan)性(xing)負載的(de)(de)單相(xiang)(xiang)整(zheng)(zheng)流(liu)電(dian)(dian)路為含奇次(ci)諧(xie)(xie)波(bo)(bo)(bo)(bo)的(de)(de)電(dian)(dian)流(liu)型諧(xie)(xie)波(bo)(bo)(bo)(bo)源。而容(rong)(rong)性(xing)負載的(de)(de)單相(xiang)(xiang)整(zheng)(zheng)流(liu)電(dian)(dian)路,由于電(dian)(dian)容(rong)(rong)電(dian)(dian)壓(ya)會通過(guo)整(zheng)(zheng)流(liu)管向電(dian)(dian)源反饋,屬于電(dian)(dian)壓(ya)型諧(xie)(xie)波(bo)(bo)(bo)(bo)源,其諧(xie)(xie)波(bo)(bo)(bo)(bo)含量與(yu)電(dian)(dian)容(rong)(rong)值的(de)(de)大(da)(da)小(xiao)有關(guan),電(dian)(dian)容(rong)(rong)值越大(da)(da),諧(xie)(xie)波(bo)(bo)(bo)(bo)含量越大(da)(da)。變頻(pin)電(dian)(dian)路諧(xie)(xie)波(bo)(bo)(bo)(bo)源由于采用(yong)的(de)(de)是相(xiang)(xiang)位(wei)控(kong)制(zhi),其諧(xie)(xie)波(bo)(bo)(bo)(bo)成(cheng)分不僅含有整(zheng)(zheng)數(shu)(shu)倍(bei)數(shu)(shu)的(de)(de)諧(xie)(xie)波(bo)(bo)(bo)(bo),還含有非整(zheng)(zheng)數(shu)(shu)倍(bei)數(shu)(shu)的(de)(de)間諧(xie)(xie)波(bo)(bo)(bo)(bo)。
