感应加热设备的滤波电抗器故障如何维修

　 　感应加热设备的滤波电抗器线圈绝缘损坏，线圈匝间击穿短路时，低直流电压，低直流电流可以起动；加大直流电压，由于电感量下降，电路中电流突变造成过流；这故障原因为线圈对铁芯短路时，造成整流电路对地短路可能使整流晶闸管击穿；电抗器声音异常，铁芯或气隙未夹紧或三相电压有波动；感应加热设备的滤波电抗器线圈水路堵塞制造成。

How to Repair the Fault of Filter Reactor of Induction Heating Equipment

The insulation of the filter reactor coil of the induction heating equipment is damaged. When the coil is broken down and short-circuited between turns, low DC voltage and low DC current can start; if the DC voltage is increased, due to the decrease in inductance, the current in the circuit suddenly causes overcurrent; the cause of the fault When the coil is short-circuited to the iron core, the short-circuit of the rectifier circuit to the ground may cause the rectifier thyristor to break down; the sound of the reactor is abnormal, the iron core or air gap is not clamped or the three-phase voltage fluctuates; the filter reactor coil waterway of the induction heating equipment Blockage is made.
