    干式变压器就是铁芯和绕组不浸渍在绝缘油中的变压器。干式变压器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。干式变压器的安全运行和使用寿命有着很大的关系。为了使干式变压器能够安全运行,下面跟随Ameya360电子元器件采购网来看看如下关于变压器的型号分类和保养方法。

干式变压器的型号分类和保养方法

    型号分类:

    1、按电压等级分:1000KV,750KV,500KV,330KV,220KV,110KV,66KV,35KV,20KV,10KV,6KV,0.66KV,0.38KV,0.22KV等。

    2、按绝缘散热介质分:干式变压器,油浸式变压器,其中干式变压器又分为:SCB环氧树脂浇注干式变压器和SGB10非包封H级绝缘干式变压器。

    3、按铁芯结构材质分:硅钢叠片变压器,硅钢卷铁芯变压器,非晶合金铁芯变压器。

    4、按设计节能序列分:SG,SJ,S7,S9,S11,S13,S15。

    5、按相数分:单相变压器,三相变压器。

    6、按容量来说国现在变压器的额定容量是3KVA,5KVA,10KVA,15KVA,20KVA,25KVA,30KVA,40KVA,50KVA,80KVA,100KVA,125KVA,160KVA,200KVA,250KVA,315KVA,400KVA,500KVA,630KVA,800KVA,1000KVA,1250KVA,1600KVA,2000KVA,2500KVA,3150KVA,4000KVA,5000KVA等。

    保养方法:

    1、清扫瓷套管和变压器线圈,防止爬电现象发生

    2、检查线圈有无开裂及放电痕迹,有的话,及时联系变压器生产厂家进行检测,确定能否再次投运

    3、检查硅胶垫等缓冲件是否老化失效,及时更换。

    4、检查变压器所有紧固件是否紧固,防止线圈移位和噪声过大,干式变压器性能下降。

    5、检查电气连接螺栓是否紧固,防止接触电阻过大,烧蚀连接处,造成事故

    6、检查电气连接处是否锈蚀,清理干净,防止接触电阻过大。

    7、清理铁心上面的灰尘和异物,避免铁芯多点接地。

    8、检查高压引线的绝缘距离,保证用电安全。

    9、检查外壳是否有漏洞,防止动物进入变压器室。

    10、检查变压器风机是否能正常运行。

    11、测量铁心对地、线圈对地绝缘,保证干式变压器绝缘可靠。

    12、检查变压器室闭锁是否可靠运行。

    13、检查有载开关能否可靠运行。

    以上就是Ameya360电子元器件采购网关于《干式变压器的型号分类和保养方法讲解》的相关内容介绍,一般干式变压器主要适用在室内或者组合式箱式变电站,比如局部照明、高层建筑、机场,码头CNC机械设备等场所。
