Problems solved by technology

[0003] In the traditional electrostatic precipitator power supply, most of its high-voltage generators use three-phase bridge six-pulse rectification to obtain DC high voltage. The DC high voltage output of this type of power supply has a large ripple coefficient and a high spark rate, and it is difficult to generate higher voltage. Voltage level, at the same time, a large number of low-order harmonics will be generated, polluting the power grid

Abstract

The invention provides a 220 kV ultrahigh-voltage electrostatic dust removal power supply, which obtains a 220 kV twelve-pulse ultrahigh-voltage direct current through a six-phase twelve-pulse rectifier transformer and a three-phase rectifier bridge connected in series. According to the invention, the ripple coefficient of the dust removal power supply is reduced, the corona power of the dust remover is improved, the driving speed of the dust is increased, so that the dust removal efficiency is improved, and meanwhile, the pollution of a low-order harmonic waves to a power grid is effectivelyreduced, which can achieve energy conservation and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a 220kV ultra-high voltage electrostatic precipitator power supply, which is suitable for special dust removal power supplies for electrostatic precipitators in the fields of metallurgy, chemical industry and energy. Background technique [0002] The electrostatic precipitator uses a high-voltage and strong electric field to cause corona discharge between the cathode and anode in the dust removal body, ionize the gas, and generate a large number of ions and electrons, so that the dust particles are charged, and under the action of the electric field force, the dust A dust removal device in which particles move toward the poles and are captured. The dust removal efficiency of the electrostatic precipitator depends on the driving speed of the dust, and the driving speed of the dust is proportional to the corona power. It can be seen that to improve the dust remov...
