广西桥巩水电站发电机组定子铁芯组装工作在现场进行,根据国家规程规范规定,对现场叠压装配的定子铁芯进行铁芯损耗试验,通过铁损试验检查定子铁芯压紧螺栓的压紧情况和发现铁芯局部发热的故障点及绝缘性能。本次试验通过对定子铁损试验接线方式择优选择、试验参数合理的计算和试验结果详细的分析,使试验误差降低到最小值,单位铁芯损耗值等各项指标均优于国家或厂家的标准值,为电站今后定子检修提供参考。
The work of assembling the stator iron core of Qiaogong Hydropower Station in Guangxi is carried out on site. According to the regulations of the state regulations, the iron core loss test is carried out on the laminated stator iron core. The iron core damage test is used to check the compression of the stator iron core compression bolt Situation and found that the core of the local heating fault and insulation properties. This test through the stator iron loss test wiring options, the rational calculation of test parameters and test results detailed analysis of the experimental error to a minimum, the unit core loss values and other indicators are better than the country or manufacturer Standard value, provide reference for the future maintenance of the stator.
