Abstract

The invention discloses a three-phase L-C constant current source high-voltage power supply, which is mainly characterized in that the three-phase power supply is respectively connected with three groups of L-C resonance four-end network converters from an input end, the three groups of L-C resonance four-end network converters are connected with a high-voltage generator, the high-voltage generator is connected with a rectifying silicon stack, and the rectifying silicon stack is connected with a load system. The three-phase L-C constant current source high-voltage power supply is used for replacing a traditional single-phase L-C constant current source high-voltage direct current dust-removing power supply device. Besides having the following technical characteristics of a single-phase L-C constant current source high-voltage power supply: constant current, a positive feedback, a parallel modular design, a high power factor, complete sinusoidal wave of input and output voltage and the like, the three-phase L-C constant current source high-voltage power supply further has the following advantages of a three-phase symmetrical load, a high density of aureole current, an effective reduction of circuit consumption and idle work consumption, lower power supply cost, and continuity and reliability of work. Compared with a single-phase power supply, the three-phase L-C constant current source high-voltage power supply is more suitable for being designed into a power supply with larger power on technology and process aspects.

Description

technical field [0001] The invention relates to a high-voltage dust removal power supply device using a three-phase L-C constant current source. Background technique [0002] The traditional single-phase L-C constant current source high-voltage DC power supply in the prior art has the advantages of constant current output characteristics, high power factor, continuous and reliable operation, etc., and has been used in many special dust removal environments, such as electric demisting devices and electric coking devices. be widely used. Its shortcomings are: since the constant current source high-voltage DC power supply adopts single-phase power supply, it is easy to cause grid imbalance and affect the safety of the power grid, and the manufacturing cost of single-phase large-capacity constant current source high-voltage power supply is high. Contents of the invention [0003] The invention provides a three-phase balanced load, which can effectively reduce line loss and re...
