高壓電解電容一般有哪幾種？

答：高壓電解電容我們通常所說的大電容，一般有兩個(gè)，由于其耐壓值特別高，所以體積非常大。按容量分，高壓電解電容一般有330uf、470uf、680uf、820uf、1000uf、1200uf等，耐壓值一般是200V，耐溫85度。

需要控制的電機(jī)及變頻器自身

1）電機(jī)的極數(shù)。一般電機(jī)極數(shù)以不多于(極為宜，否則變頻器容量就要適當(dāng)加大。

2）轉(zhuǎn)矩特性、臨界轉(zhuǎn)矩、加速轉(zhuǎn)矩。在同等電機(jī)功率情況下，相對(duì)于高過載轉(zhuǎn)矩模式，變頻器規(guī)格可以降額選取。3）電磁兼容性。為減少主電源干擾，使用時(shí)可在中間電路或變頻器輸入電路中增加電抗器，或安裝前置隔離變壓器。一般當(dāng)電機(jī)與變頻器距離超過50m時(shí)，應(yīng)在它們中間串入電抗器、濾波器或采用屏蔽防護(hù)電纜
