一种防止断裂的风力发电机转子过桥线结构

A Kind of Breakage-proof Rotor Bridge Link Structure in the Wind Turbine

通过对某型1.5MW双馈风力发电机转子过桥线断裂原因进行分析,提出了一种防止断裂的转子过桥线结构。改进后的过桥线固定在支架上不再悬空,大幅减小了离心力带来的应力集中,解决了过桥线断裂问题。

Based on the analysis on the breakage cause of the rotor bridge link of the 1. 5MW doubly-fed wind turbine, a kind of breakage-proof rotor bridge links structure is proposed, in which the bridge line is fixed on the bracket and no longer suspended, so as to greatly reduce the stress concentration caused by centrifugal force, and solve the problem of bridge link breakage.
