发(fa)电(dian)(dian)(dian)机(ji)(ji)(ji)的(de)绝(jue)(jue)缘(yuan)(yuan)等(deng)(deng)级(ji)(ji)(ji)决(jue)定(ding)于它所采用的(de)绝(jue)(jue)缘(yuan)(yuan)材料(liao)的(de)耐热等(deng)(deng)级(ji)(ji)(ji)。若一台电(dian)(dian)(dian)机(ji)(ji)(ji)主要(yao)部件的(de)绝(jue)(jue)缘(yuan)(yuan)结构采用不同(tong)耐热等(deng)(deng)级(ji)(ji)(ji)的(de)绝(jue)(jue)缘(yuan)(yuan)材料(liao),其绝(jue)(jue)缘(yuan)(yuan)等(deng)(deng)级(ji)(ji)(ji)按绝(jue)(jue)缘(yuan)(yuan)材料(liao)的(de).低耐热等(deng)(deng)级(ji)(ji)(ji)考核。发(fa)电(dian)(dian)(dian)机(ji)(ji)(ji)绝(jue)(jue)缘(yuan)(yuan)等(deng)(deng)级(ji)(ji)(ji)无优劣之分(fen),具体要(yao)看所在的(de)应用场合(he)。本篇(pian)由专业柴油发(fa)电(dian)(dian)(dian)机(ji)(ji)(ji)厂家(jia)--江苏星光发(fa)电(dian)(dian)(dian)设备有限公(gong)司(si)为大家(jia)介(jie)绍下发(fa)电(dian)(dian)(dian)机(ji)(ji)(ji)的(de)绝(jue)(jue)缘(yuan)(yuan)等(deng)(deng)级(ji)(ji)(ji)的(de)相关说(shuo)明。

其具体(ti)等级是:

分A、E、B、F、H级(ji)。

允(yun)许温升是指电(dian)动机的温度(du)与周围环(huan)境(jing)温度(du)相比升高的限度(du)。

绝缘的(de)温度等(deng)级(ji)A级(ji)E级(ji)B级(ji)F级(ji)H级(ji)

至高(gao)允(yun)许温(wen)度(℃)105 120 130 155 180

绕组温升限值(zhi)(K)60 75 80 100 125

性能参考温(wen)度(℃)80 95 100 120 145

所谓温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)是(shi)(shi)指电(dian)动(dong)(dong)机(ji)(ji)高出环(huan)境的(de)(de)温(wen)(wen)(wen)(wen)度(du)(du)(du)。例如环(huan)境温(wen)(wen)(wen)(wen)度(du)(du)(du)是(shi)(shi)30℃,电(dian)动(dong)(dong)机(ji)(ji)温(wen)(wen)(wen)(wen)度(du)(du)(du)是(shi)(shi)80℃,则(ze)温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)就(jiu)(jiu)是(shi)(shi)50℃。电(dian)动(dong)(dong)机(ji)(ji)铭牌上(shang)的(de)(de)温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng),是(shi)(shi)指在(zai)(zai)规定(ding)的(de)(de)环(huan)境温(wen)(wen)(wen)(wen)度(du)(du)(du)下(xia)(一(yi)般为35℃),绕(rao)组(zu)的(de)(de)允(yun)许温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng),即绕(rao)组(zu)的(de)(de).高允(yun)许温(wen)(wen)(wen)(wen)度(du)(du)(du)与规定(ding)环(huan)境温(wen)(wen)(wen)(wen)度(du)(du)(du)之(zhi)差。例如铭牌上(shang)的(de)(de)温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)为60℃,表明在(zai)(zai)环(huan)境温(wen)(wen)(wen)(wen)度(du)(du)(du)为35℃时(shi),即绕(rao)组(zu)的(de)(de)温(wen)(wen)(wen)(wen)度(du)(du)(du)不得超过(guo)(guo)95℃。绕(rao)组(zu)的(de)(de)允(yun)许温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)是(shi)(shi)由发电(dian)机(ji)(ji)绝(jue)缘(yuan)(yuan)等级(ji)(ji)决定(ding)的(de)(de),不同的(de)(de)绝(jue)缘(yuan)(yuan)等级(ji)(ji)有不同的(de)(de)允(yun)许温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng),所以一(yi)般电(dian)动(dong)(dong)机(ji)(ji)铭牌上(shang)都标明了绝(jue)缘(yuan)(yuan)等级(ji)(ji)。电(dian)动(dong)(dong)机(ji)(ji)在(zai)(zai)正(zheng)常运(yun)行时(shi),实际温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)如果超过(guo)(guo)了允(yun)许温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng),就(jiu)(jiu)说明电(dian)动(dong)(dong)机(ji)(ji)有故障或(huo)电(dian)源电(dian)压不正(zheng)常。电(dian)动(dong)(dong)机(ji)(ji)温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)超过(guo)(guo)允(yun)许值时(shi),绝(jue)缘(yuan)(yuan)材料将(jiang)加速老(lao)化,其机(ji)(ji)械强(qiang)度(du)(du)(du)和绝(jue)缘(yuan)(yuan)强(qiang)度(du)(du)(du)将(jiang)迅速降低,使电(dian)动(dong)(dong)机(ji)(ji)寿命(ming)大(da)大(da)缩短,一(yi)般电(dian)动(dong)(dong)机(ji)(ji)在(zai)(zai)允(yun)许温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)下(xia)运(yun)行可以用20年(nian)左右,但若高出额(e)定(ding)温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)百分之(zhi)四十运(yun)行就(jiu)(jiu)只能(neng)用几(ji)十天,高出额(e)定(ding)温(wen)(wen)(wen)(wen)升(sheng)(sheng)(sheng)到(dao)一(yi)定(ding)时(shi)运(yun)行,3小时(shi)就(jiu)(jiu)会烧坏(huai)。
