Abstract: A method replaces a saturable core reactor (SCRs) in a rectifier power transformer disposed in a transformer vault at its field location. The transformer has an oil-filled tank housing the SCRs. The tank has a manhole opening therein. A busbar structure is associated with each SCR. The method drains the oil from the tank. A busbar structure is disconnected from an associated SCR. The disconnected busbar structure is moved away from the transformer. The SCR is removed from the tank through the manhole opening and is lowered. The SCR is then conveyed from the transformer vault. A replacement SCR is moved to be adjacent the manhole opening and is then slid through the manhole opening and into the tank to a certain location. The busbar structure is moved so as to be associated with a replacement SCR and is connected to the replacement SCR.

Abstract translation: 一种方法在其现场位置替换设在变压器保险库中的整流器电力变压器中的可饱和核心电抗器（SCR）。 变压器有一个储油罐，装有SCR。 坦克里有一个人孔。 汇流排结构与每个SCR相关联。 该方法从油箱中排出油。 汇流排结构与相关的SCR断开连接。 断开的母线结构远离变压器。 SCR通过人孔开口从罐中移出并降低。 然后从变压器保险库传送SCR。 替换SCR移动到与人孔开口相邻，然后滑动通过人孔开口并进入罐中到某一位置。 母线结构被移动以与替换SCR相关联并且连接到替换SCR。
