此外，還可采用液體介質(zhì)冷卻，例如水的相對冷卻能力為空氣的50倍，帶走同樣的熱量，所需水的流量比空氣小得多。因此，在線圈里采用一部分空心導(dǎo)線，導(dǎo)線中通水冷卻，就可以**降低電機(jī)溫升，延緩絕緣老化，增長電機(jī)壽命。1956年，英國*****臺(tái)12000千瓦定子線圈水內(nèi)冷汽輪發(fā)電機(jī)。1958年，中國由浙江大學(xué)、上海電機(jī)廠首先研制成***臺(tái)定、轉(zhuǎn)子線圈都采用水內(nèi)冷的12000千瓦雙水內(nèi)冷汽輪發(fā)電機(jī)，為這種冷卻方式奠定了基礎(chǔ)。世界一些國家在大容量電機(jī)中也***采用水內(nèi)冷技術(shù)，并制造出了幾十萬到一百多萬千瓦的巨型發(fā)電機(jī)。除了水冷外，液體冷卻介質(zhì)還可使用變壓器油，其相對導(dǎo)熱能力約為水的40%，絕緣性能好，可將發(fā)電機(jī)額定電壓提高到幾萬伏，從而節(jié)約了升壓變壓器的投資。近年來，還在研究用氟利昂作為冷卻介質(zhì)的蒸發(fā)冷卻技術(shù)。氟利昂絕緣好，很容易氣化，利用其氣化潛熱來冷卻電機(jī)，是一種有意義的探索方向。低速同步發(fā)電機(jī)多數(shù)由較低速度的水輪機(jī)或柴油機(jī)驅(qū)動(dòng)，上海進(jìn)口直流電機(jī)維修。電機(jī)磁極數(shù)由4極到60極，上海進(jìn)口直流電機(jī)維修，甚至更多。對應(yīng)的轉(zhuǎn)速為1500～100轉(zhuǎn)/分及以下。由于轉(zhuǎn)速較低，一般都采用對材料和制造工藝要求較低的凸極式轉(zhuǎn)子。凸極式轉(zhuǎn)子的每個(gè)磁極常由1～2毫米厚的鋼板疊成，用鉚釘裝成整體，上海進(jìn)口直流電機(jī)維修。濱湖區(qū)直流電機(jī)維修，宜興市聚源電機(jī)維修有限公司。上海進(jìn)口直流電機(jī)維修</p><div
