S120驱动器基本调试步骤总结
一、整流柜调试 |
上电前直流母排测量
测量直流母排对地绝缘阻值:有一个对地很小几千欧姆,但绝不能短路;直流相间阻值无穷,调换表笔后由于二极管特性阻值很小;
24V 母排测量:对地不能为零(24V 正对地7.2M,24V 负对地5.1 欧);
整流柜电压测量
整流进线柜进线电压测量(偏差正负10%)
整流进线柜进线电压与预充电断路器上火电压相位测量(相位要相同),整流进线柜进线电压与其他整流进线电压相位测量(相位要相同);(相位相同电压为0,相位不同电压690V)
注意:万用表挡位要在交流电压档,不要搞错! |
整流柜预充电断路器下火与K4 预充电接触器上火电阻阻值测量(注意是电阻
档,同一相阻值为零,不是同一相阻值为无穷);
测试合分闸逻辑
高压停电,进线断路器合闸线圈拆下X27 端子,短接几个整流柜X9 的3、4 端
子预充电完成信号
