   ä»Žç›¸æ•°å±‚面来看,可以分为单相变压器和三相变压器,其中单相变压器用于单相负荷和三相变压器组,结构简单、体积小、损耗低,主要是铁损小,适宜在负荷密度较小的低压配电网中应用和推广。而三相变压器用于三相系统的升、降电压,三个独立的绕组,通过不同的接法(如:星形、三角形),使其输入或输出三相交流电源ã€?/p><p><br/></p><p>      从冷却方式来看的话可以分为干式变压器和油浸式变压器。干式变压器主要依靠空气对流进行自然冷却或增加风机冷却,多用于高层建筑、高速收费站点用电及局部照明、电子线路等小容量变压器。油浸式变压器则依靠油作冷却介质、如油浸自冷、油浸风冷、油浸水冷、强迫油循环等ã€?/p><p><br/></p><p>       ä»Žç”¨é€”方面来看的话,有主要用于输配电系统的升、降电压的电力变压器;用于测量仪表和继电保护装置的仪用变压器如电压互感器、电流互感器;能产生高压,对电气设备进行高压试验的试验变压器以及特种变压器如电炉变压器、整流变压器、调整变压器、电容式变压器、移相变压器等ã€?/p><p><br/></p><p>       æŒ‰ä¸åŒçš„绕组形式来分的话,有两组绕有导线的线åœ?并且彼此以电感方式组合一起,用于连接电力系统中的两个电压等级的双绕组变压器;三绕组变压器每相æœ?个绕ç»?å½?个绕组接到交流电源后,另外2个绕组就感应出不同的电势,三绕组变压器一般用于电力系统区域变电站中,连接三个电压等级。自耦变电器初级和次级相联通,具有省漆包线,损耗小的特点多用于连接不同电压的电力系统,也可做为普通的升压或降后变压器用ã€?/p><p><br/></p><p>       è¿˜æœ‰ä»?a href="http://www.etarea.com" target="_self" _href="http://www.etarea.com">变压å™?/a>原材料铁芯形式来看的话,有芯式用于高压的电力变压器;用新型导磁材料,空载电流下降çº?0%的非晶合金铁芯变压器;壳式用于大电流的特殊变压器,如电炉变压器、电焊变压器或用于电子仪器及电视、收音机等的电源变压器ã€?/p><p><br/></p> </div> <div class="return"><a
