When you install a large capacity machine drive repair, please confirm transformer impedance values, the transformer capacity is appropriate. Also drive repair factory, in the following three cases, the input side of the inverter mounted on ac reactor. Especially in small and large capacity drive inverter is installed in the same place to note the following three points: ① transformer capacity exceeding 500kva ② distance between the transformer and the inverter input current value ③ less than 10m more than the inverter rated output current Because of the smaller grid inductance value of the harmonic current will be greater, so even the drive may cause damage to the bridge rectifier DC drive repair, drive repair Dandong, on the people by the Shenyang Electric Man Electric Co.
