日本SINANO(信浓)自动化备件 SE04-10WA 

1、测试整流电路

找下结果，可以判定电路已出现异常，A.到变频器内部直流电源的P端和N端，将万用表调到电阻X10档，红表棒接到P，黑表棒分别依到R、S、T，正常时有几十欧的阻值，且基本平衡。相反将黑表棒接到P端，红表棒依次接到R、S、T，有一个接近于无穷大的阻值。将红表棒接到N端，重复以上步骤，都应得到相同结果。如果有以阻值三相不平衡，说明整流桥有故障.B.红表棒接P端时，电阻无穷大，可以断定整流桥故障或启动电阻出现故障。

2、测试逆变电路

将红表棒接到P端，黑表棒分别接U、V、W上，应该有几十欧的阻值，且各相阻值基本相同。将黑表棒N端，，反相应该为无穷大，重复以上步骤应得到相同结果，否则可确定逆变模块有故障。

1. Test the rectifier circuit

Find the results, you can determine that the circuit has been abnormal, A. To the P and N ends of the DC power supply inside the inverter, the multimeter is adjusted to the resistance X10, the red meter rod is connected to P, the black meter rod is respectively according to R, S, T, and the normal resistance value is tens of ohMs, and the basic balance. Instead, the black bar is connected to the P terminal, and the red bar is successively connected to R, S, and T, with a resistance value approaching infinity. Connect the red watch rod to the N end and repeat the above steps to get the same result. If there is a three-phase imbalance with the resistance value, it indicates that the rectifier bridge is faulty. B. When the red meter rod is connected to the P end, the resistance is infinite, and it can be determined that the rectifier bridge is faulty or the starting resistance is faulty.

2. Test the inverter circuit

The red meter rod is connected to the P end, and the black meter rod is connected to U, V and W respectively, and there should be a resistance value of tens of ohm, and the resistance value of each phase is basically the same. The N end of the black watch rod, the reverse phase should be infinity, repeat the above steps should get the same result, otherwise it can be determined that the inverter module is faulty.
