Embodiment Construction
[0021] Such as figure 2 As shown, a DC pulse power supply scheme for electrostatic precipitator, the designed power supply includes a main circuit switch ② connected to the three-phase AC power ①, a DC generating unit ③ connected to the main circuit switch and a pulse generating unit ⑧ , the pulse generation unit is connected to a signal control unit ⑨, the output of the DC generation unit and the pulse generation unit is connected to the dust collector plate ④ through a DC and pulse superposition unit ⑩. Among them, the DC generation unit is composed of a power frequency transformer step-up module and a three-phase bridge uncontrolled rectification module in series; the pulse generation unit is sequentially composed of a three-phase bridge full-control rectification module ⑤, a DC-DC step-up circuit ⑥, a pulse step-up Module ⑦ constitutes. After the three-phase AC power supply is switched by the main circuit, one path is boosted and rectified by the DC generating unit to ob...
