  • The reactor is loud and dull, unstable and trembling.

  • Failure phenomenon: the device can start, but the voltage is not high, the reactor is very loud and dull, the voltage rises very unstable and trembles. From time to time, there are overcurrent or overvoltage failures, and sometimes it even burns the inverter tube, but it is good to break the rectifier part of the inverter circuit.


    Fault analysis and processing: most of this fault is the reactor has problems.

    The inductance of A. reactor is larger than that of normal. The magnetic circuit is saturated. It doesn't play the role of continuous current filtering, nor can it separate the current between AC and DC terminals. The number of turns of reactor is much higher than normal.


    The air gap plate of the B. reactor is thinner than the normal, and the inductance varies greatly. At this time, the air gap plate is thickened.
    .

    In the coil of the C. reactor, there is a phenomenon of fire and discharge between the turns of the coil and the decrease of the interturn insulation.
