●安装进线刀开关、进线电流表、电压表（可切换）和进线电压指示灯。

●安装三相全控晶闸管整流桥，实现高频焊机功率调节。

●安装平波电抗、平波电容及滤波器，以提高平波系数。

Switch Rectifying Cabinet

We integrate the switch gear cabinet part and rectifier part, besides the functions of switch cabinet, this design also has rectifying control functions on solid-state H.F. welders.

● Install incoming disconnect switch，incoming current meter，voltage meter (switchable) and incoming voltage indicator light.

● Install 3-phase full-controllable thyristor rectifying bridge to achieve power regulation of H.F. welders.

● Install flight wave reactor，flight capacitor and filter to increase flight coefficient.
