摘要： A method of fabricating an electric generator main lead bushing is provided for attaching a flange to a hollow conductor. In one application typically used for an air side flange, a gap is formed in the flange that is sized to receive an end of the conductor, a groove is formed in the conductor end, a braze alloy insert is placed into the groove, the conductor end is inserted into the gap, and the flange and the conductor are heated and cooled to provide a seal between the flange and the conductor. In another application typically used for a gas side flange, a counterbore is formed in an inner portion of the hollow conductor that is sized to receive the flange, a groove is formed in the counterbore, a braze alloy insert is placed into the groove, the flange is fitted into the counterbore, and the flange and the conductor are heated and cooled to provide a seal between the flange and the conductor.

摘要翻译： 提供一种制造发电机主引线衬套的方法，用于将法兰附接到中空导体。 在通常用于空气侧凸缘的一个应用中，在凸缘中形成一个间隙，其尺寸被设计成接收导体的端部，在导体端形成凹槽，将钎焊合金插入件放置在凹槽中，导体 端部插入到间隙中，并且法兰和导体被加热和冷却以在凸缘和导体之间提供密封。 在通常用于气体侧凸缘的另一应用中，沉孔形成在中空导体的内部，其尺寸被设计成容纳凸缘，凹槽形成在沉孔中，钎焊合金插入件放置在凹槽中， 法兰被安装到沉孔中，法兰和导体被加热和冷却以在凸缘和导体之间提供密封。
