改变配电变压器结线组别实现抽油机降压节能

Change Distribution Transformer Connection to Realize Pumping Unit's Energy Conservation

针对许多游梁式抽油机用电动机不能直接应用D/Y切换技术实现节能的困难,提出了一种改变配电变压器结线,实现抽油机电动机节能的新方法,同时讨论了实施这种新方法时的具体问题及解决方法,总结了该方法的优缺点。

In view of the difficulty that many beam pumping unit to use electric motor can not directly to apply the D/Y switch technology for realizirig energy conservation, this paper proposed a new method which changes distribution transformer connection to realize any pumping unit＇s electric motor and the energy conservation effect for equation of the D/Y switch technology, meanwhile discussed several details questions and its solution when implements this new method. It summarized the advantages and disadvantages of this method as well.
