Abstract
The utility model relates to a power supply for high-voltage electro-static cleaner, which is characterized in that the power supply for high-voltage electro-static cleaner adopts three-phase alternating current; the three-phase alternating current is full-wave rectified by a silicon stack after the three-phase alternating current is transformed through the two winding transformers of a triangular and a star type; a twelve-phase rectification direct current voltage is obtained when the three-phase alternating current is added; then the direct current voltage can be acted as the power supply of the electro-static cleaner after filtered. The power supply for high-voltage electro-static cleaner has the advantages of high energy conversion rate, small pulse coefficient, simple structure, little possibility of failure, low cost, etc.
Description
The utility model belongs to the improvement of high-voltage electrostatic dust separator power supply architecture.
Because software feature electrostatic precipitator power supply is compared with hardware features electrostatic precipitator power supply, has advantages such as anion conversion efficiency height, good dedusting effect, and make it obtain using widely.At present for advanced software feature electrostatic precipitator power supply is China's 88205985.8 patents, but it also comes with some shortcomings: (1) owing to adopt high-frequency conversion circuit, the circuit structure complexity, and power device is often burnt, so its poor reliability; (2) along with the fluctuation of load, the also proportional variation of AC ripple; (3) energy is through the multiple conversions of AC-DC-high-frequency AC-DC, loses greatlyyer, and conversion efficiency is low; (4) device line complexity, cost height.The purpose of this utility model is exactly at above-mentioned weak point, designs a kind of high-voltage electrostatic dust separator power supply and solves existing problem.
Principal character of the present utility model is: designed power supply adopts three-phase alternating current behind the triangle and two winding transformations of star of transformer, again through with the corresponding two groups of silicon stacks of two windings (6 every group) full-wave rectification after addition, obtain 12 commutating phase DC voltages, after inductor filtering, can be as the power supply of electrostatic precipitator.Accompanying drawing 1 is the circuit theory diagrams of the designed high-voltage electrostatic dust separator power supply of the utility model.
Structure from figure and combination are calculated and can be found out, the power conversion mode of the high-voltage electrostatic dust separator power supply that the utility model is designed is AC-DC, and its conversion ratio can reach more than 95%, and does not change with the fluctuation of load, ripple factor is 2.85%, and its circuit is simple, cost is low.The parameter of its each winding of transformer, and the model of silicon stack and inductor all are to calculate the back according to the desired voltage and current of electrostatic precipitator to determine that silicon stack can be selected the series of 2DL or 2CL for use.
