施耐德控制器 TSXP576634M
电气方面暂时没发现问题,当时初步判断,可能是设备机械部分出了问题,但机修人员打开设备箱体检查没发现问题。于是只能继续查找电气方面的问题,这一查还真就发现了一点问题,发现电机在低速转动的时候有不明显的停顿感,不仔细的话很难看出来。后来在电机连接器上稍加力度,发现电枢电流急剧变大,就排除了设备机械问题。
再次检查电机和电机轴承没发现明显问题后,考虑是控制器的问题。查看控制器参数没问题,拆开控制器也没明显问题,无奈只能让专业维修点给做个检测。经过他们检查还真有问题,说是里面的整流模块有问题。等了三天,换了模块的控制器装了上去。
满怀希望的开机试机,问题依旧。询问维修点,给提供各种方法解决,都无济于事,看来也不是控制器造成的这种故障。当时真是无计可施了,都打算放弃,然后找厂家售后了。放弃前打算再挣扎一下,准备再查查电机内部,电机里面灰尘有点多,弄的满手都是灰。于是让新来的小同事找个吹风机吹一下,结果小同事一脸紧张的过来说,他把电机线吹断了。当时那个激动啊,多大的风能把那么粗的线吹断,应该是电机出问题了,赶紧过去查看。
