制動(dòng)電阻發(fā)熱是很正常的現(xiàn)象,但是如果是發(fā)熱嚴(yán)重那就說(shuō)明是不正常了,我們應(yīng)當(dāng)查找原因,及時(shí)解決問(wèn)題??赡芎芏嗳诉€不太了解這方面的知識(shí),那么電工之家?guī)私庖幌孪嚓P(guān)的東西,說(shuō)不定什么時(shí)候就用上了。
1、制動(dòng)的時(shí)候電阻發(fā)熱是正常了,只要不超出正常范圍;
2、變頻器啟動(dòng)制動(dòng)頻繁的時(shí)候,制動(dòng)電阻發(fā)熱嚴(yán)重,頻率下降的時(shí)候發(fā)熱減少屬于正?,F(xiàn)象;
3、制動(dòng)電阻發(fā)熱嚴(yán)重時(shí),注意查看其功率大小,只要沒(méi)超出額定范圍也是OK的;

4、如果變頻器還沒(méi)制動(dòng)而制動(dòng)電阻就已經(jīng)嚴(yán)重發(fā)熱,那說(shuō)明肯定有故障;
5、當(dāng)電阻發(fā)熱嚴(yán)重,電阻功率又超過(guò)額定功率的時(shí)候就要更換額定功率較大的電阻了;
6、長(zhǎng)時(shí)間嚴(yán)重發(fā)熱會(huì)有可能導(dǎo)致制動(dòng)電阻燒壞,電壓過(guò)大造成停機(jī),是系統(tǒng)突然中斷,后果不堪設(shè)想,因?yàn)橐坏╇娮鑷?yán)重發(fā)熱一定要及時(shí)關(guān)注,發(fā)生意外。
