High-frequency dust removing transformer

Abstract

The invention discloses a high-frequency dedusting transformer which comprises a low voltage winding, a high voltage winding and an iron core; the iron core takes a 'Square' shape which consists of two half-'Square' shapes in butt joint, and the iron core is made from ferrite material; the output voltage of the low voltage winding is 0.68kV, the output voltage of the high voltage winding is 66kV, and the working frequency of the transformer is 7-8kHz. The low voltage winding is wound by copper foil, the high voltage winding is of multi-pancake continuous type, and insulation and cooling are realized by transformer oil. Compared with the prior art, the high-frequency dedusting transformer has the advantages that the operation is stable, the dedusting efficiency is increased by about 20% relative to that of a power frequency transformer, the volume of the transformer is decreased by about 10%, which facilitates the installation of the whole set of equipment, and the high-frequency dedusting transformer is applicable to environment-friendly dedusting equipment.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to a high-frequency dust removal transformer used in flue gas dust removal equipment. Background technique [0002] The combustion process of coal, oil, natural gas and other fuels is the most important source of pollutants delivered to the atmosphere. my country's air pollution is soot-type pollution. The total amount of coal-burning pollution accounts for 96% of the total fuel combustion emissions. A large amount of smoke and dust pollution has caused a sharp drop in urban transparency and shortened daytime sunshine hours, which have seriously affected human life and survival. Therefore, the state has formulated a series of policies and regulations to prevent and control air pollution, and take mandatory measures for energy conservation and emission reduction. Therefore, actively using new technologies to reduce the generation and discharge of pollutants has become an urgent issue for...

AI Technical Summary

Problems solved by technology

Therefore, the disadvantages of this transformer are: 1. Due to the low operating frequency, the rectified waveform and impedance matching of the output voltage of the transformer are difficult to meet the dust removal requirements. When the dust specific resistance is too high and partial discharge occurs, the transformer’s The output voltage has a great influence, and the fluctuation of the output voltage of the transformer greatly reduces the dust removal efficiency

2. Under frequent load current fluctuations, the efficiency of dust removal is also greatly reduced, and the service life of the step-up transformer itself will also be affected
