BP2頻敏變阻器
一、用途
1、BP2頻敏變阻器用于繞線式三相異步電動(dòng)機(jī)的起動(dòng),接在三相異步電動(dòng)機(jī)的轉(zhuǎn)子回路。
BP2頻敏變阻器是由三相繞組,厚鋼板做成的鐵芯制成。電機(jī)起動(dòng)時(shí),因轉(zhuǎn)差率高,感抗大,可限制起動(dòng)電流,隨著轉(zhuǎn)速增加,差率下降,感抗減小,轉(zhuǎn)子電流增加。
完成起動(dòng)過程,BP2頻敏變阻器可長(zhǎng)期接在轉(zhuǎn)子回路。也可用接觸器予以短接。
2、BP2-700系列頻敏變阻器系接于三相交流50赫芝繞線型異步電動(dòng)機(jī)(JR、JRZ、JRQ等)轉(zhuǎn)子回路中,作為短時(shí)起動(dòng)之用。
電動(dòng)機(jī)起動(dòng)完畢后,應(yīng)將變阻器切除。切除用的接觸器,刀開關(guān)等由用戶自備。
3、BP2-400、600系列頻敏變阻器,接于三相交流落50赫茲繞線型異步電動(dòng)機(jī)(JR、JRZ、JRQ型)轉(zhuǎn)子同路中,作為重復(fù)短時(shí)起動(dòng),及反接或動(dòng)力制動(dòng)之用。
BP2-400、600系列變阻器,允許長(zhǎng)期接于轉(zhuǎn)子回路中,可不另設(shè)短接器。
