Generator rotor pole crossover |
摘要 |
The present invention increases the life of a pole crossover while minimizing the need for timely inspections and costly replacements. The present invention splits the pole crossover band 4 at one or more locations along its circumference and then joins the multiple arcs with a flexible member 10 , such as an omega shaped bow. As deflection related stresses 8 increase, the circumference of the pole crossover band, the flexible member 10 allows for a natural expansion point in the otherwise rigid material. This relieves stresses that would otherwise be transferred to the connection point 6 between the pole crossover and the generator windings that can cause cracking and eventually generator failure.
