1,How to deal with the interference between inverter PLC andother delicate instrument?
Answer:
(1) The harmonic interference between input side of invertergrid system:
a: Add input filtercapacitors absorb board to the input side of inverter.
b: Add a magnetic ring on the power cable (220V power supply)add single-phase filterisolating transformer.
c: Inverter should be independently grounded.
(2) The interference between output side of inverter delicate instrument:
a: Add magnetic rings to the three-phase cables of output side of inverter. Please put more ringsadd filters.
b: Add magnetic rings to test output signal cables before they are connected to signal processing boardsignal collecting system.
c: On the signal processing board, please connect ceramic capacitor in parallel between two disturbed signal cables.
d: Separate signal cablespower cables,please adopt shielding cable for signal cable.
e: Please decrease carrier-wave value correctly.
