1. 抑制浪涌:
在大功率電力電子電路中,合閘瞬間,往往產(chǎn)生一個很大的沖擊電流(浪涌電流),浪涌電流雖然作用時間短,但峰值卻很大。比如,電弧爐、大型軋鋼機,大型開關(guān)電源,UPS電源,變頻器等,開機浪涌電流往往超過正常工作電流的100倍以上。在輸入側(cè)串接電抗器,能有效的抑制這種浪涌電流。『合閘瞬間,電抗器呈高阻態(tài)(相當于開路)』。
2. 抑制諧波電流
隨著電力電子技術(shù)的廣泛應用,我們的電網(wǎng)中增加了大量的非線性負載,比如,AC-DC電源,UPS,變頻器等,它們都是以開關(guān)方式工作的。這些以開關(guān)方式工作的用電設備,往往變成了諧波電流的發(fā)生源,“污染”電網(wǎng),使電網(wǎng)電壓波形畸變。諧波的危害之一便是中心線過載發(fā)熱燃燒。電抗器的接入,能有效抑制諧波污染。

電抗器的作用如下:
電路中電抗器一般有兩個作用:①抑制浪涌(電壓、電流);②抑制諧波電流。
1. 抑制浪涌:
在大功率電力電子電路中,合閘瞬間,往往產(chǎn)生一個很大的沖擊電流(浪涌電流),浪涌電流雖然作用時間短,但峰值卻很大。比如,電弧爐、大型軋鋼機,大型開關(guān)電源,UPS電源,變頻器等,開機浪涌電流往往超過正常工作電流的100倍以上。在輸入側(cè)串接電抗器,能有效的抑制這種浪涌電流。『合閘瞬間,電抗器呈高阻態(tài)(相當于開路)』。
2. 抑制諧波電流
隨著電力電子技術(shù)的廣泛應用,我們的電網(wǎng)中增加了大量的非線性負載,比如,AC-DC電源,UPS,變頻器等,它們都是以開關(guān)方式工作的。這些以開關(guān)方式工作的用電設備,往往變成了諧波電流的發(fā)生源,“污染”電網(wǎng),使電網(wǎng)電壓波形畸變。諧波的危害之一便是中心線過載發(fā)熱燃燒。電抗器的接入,能有效抑制諧波污染。
