目的
2
风电联轴器力矩限制器打滑失效会导致风电机组传动系统受损。以5 MW机组联轴器力矩限制器为对象,探究打滑失效关键原因,为提升可靠性及机组稳定性提供支撑。
方法
2
结合故障数据、现场拆解结果与标定测试数据开展多维度分析。计算端转矩,分析转速匹配性及转矩波动;拆解检测摩擦片磨损与结构缺陷;通过出厂标定测试研究转矩波动及标定方法影响。
结果
2
失效主因包括变流器信号不稳产生超额冲击转矩、两瓣式悬臂结构致摩擦片偏磨、标定方法导致转矩控制精度不足。优化后可有效解决打滑问题,延长使用寿命,提升运行可靠性。
Objective
2
Slipping failure of the wind power coupling torque limiter could cause damage to the transmission system of wind turbines. The coupling torque limiter of a 5 MW unit was taken as the research object
and the key causes of its slipping failure were explored to provide support for improving reliability and unit stability.
Methods
2
A multi-dimensional analysis was adopted
combined with fault data
on-site disassembly results
and calibration test data. End torque was calculated
and speed matching and torque fluctuation were analyzed; the failure limiter was disassembled to inspect friction plate wear and structural defects; and calibration tests were conducted to study the influence of torque fluctuation and calibration methods.
Results
2
The main causes of failure include: unstable converter signals leading to excessive impact torque; the two-lobe cantilever structure causing uneven wear of friction plates; and inadequate torque control accuracy due to the calibration method. After optimization
the slipping problem can be effectively solved
and the service life and operational reliability were improved.
