Three-phase high voltage power supply design for electrostatic precipitator based on phase sequence self-adaption and redundant spark detection
The three-phase power supply has the advantages of small voltage ripple, balance three-phase load and high output power. It is suitable for application in the large electrostatic precipitators of the sintering machine head and the coal fired boiler. This paper designs the three-phase power supply based on phase sequence self-adaption and redundant spark detection. The winding connection mode of Y-Y and the full-bridge rectification circuit are used. This is beneficial to the energy saving, and the energy saving effect is also analyzed. In addition, the three-phase intermittent control is realized. The comparative experiments of voltage boosting between the three-phase power supply and the single-phase power supply demonstrate that the proposed design is effective.
Electrostatic Precipitator Power Supply- A Review
The aim of this work is to analyze and understand the operation of various power supplies evolved for the application of Electrostatic Precipitator (ESP). From this work it is possible to identify the problems arouse in the power supply section and the way they get resolved can be understand. Also the problems still need to be solved has to be identified and the possible solutions has to be formed.
