style="text-indent:25px">電機(jī)比過去更容易燒毀由于絕緣技術(shù)的不斷發(fā)展，在電機(jī)的設(shè)計(jì)上既要求增加出力，又要求減小體積，使新型電機(jī)的熱容量越來越小，過負(fù)荷能力越來越弱；再由于生產(chǎn)自動(dòng)化程度的提高，要求電機(jī)經(jīng)常運(yùn)行在頻繁的起動(dòng)、制動(dòng)、正反轉(zhuǎn)以及變負(fù)荷等多種方式，對(duì)電機(jī)保護(hù)裝置提出了更高的要求。另外，電機(jī)的應(yīng)用面更廣，常工作于環(huán)境極為惡劣的場合，如潮濕、高溫、多塵、腐蝕等場合。所有這些，造成了電機(jī)更容易損壞，尤其是過載、短路、缺相、掃膛等故障出現(xiàn)頻率較高。傳統(tǒng)的保護(hù)裝置保護(hù)效果不甚理想：傳統(tǒng)的電機(jī)保護(hù)裝置以熱繼電器為主，但熱繼電器靈敏度低、誤差大，制動(dòng)器廠家、穩(wěn)定性差，保護(hù)不可靠。事實(shí)也是這樣，制動(dòng)器廠家，制動(dòng)器廠家，盡管許多設(shè)備安裝了熱繼電器，但電機(jī)損壞而影響正常生產(chǎn)的現(xiàn)象仍普遍存在。永磁電動(dòng)機(jī)的電刷使用單性金屬片或金屬石墨電刷、電化石墨電刷。制動(dòng)器廠家</p><div
