KBSGY-40/1.14型干式变压器制造

Developing KBSGY-40/1.14 Dry-type Transformer

由于煤矿井下没有满足电焊机需要的～380V电源，所以利用闲置设备，开发了一种干式变压器。该变压器不仅能满足井下焊接需要，还可为绞车、水泵提供～660V电源。介绍了该变压器的制造方案，分析了电气工作原理，并给出了该变压器的使用规则。

Because of no power of 380 voltage for electric welding machine under mining, design and manufacture a dry - type transformer, benefiting abandoned equipment. It can not only generate a kind of power for welding, but also provide power of 660 voltage for winches and water pumps under mining. Describes the making scheme of the transformer, analyzes the electricity principle, and gives the using rules of the transformer.
