Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 , figure 2 , image 3 As shown, a high-power active filter reactor includes a box body 1, a cylindrical iron core 2 and a coil 3. The box body 1 includes a bottom plate 4, a box body cover plate 5, a front panel 6, a rear panel 7 and The two side wall plates 8 , the box body cover plate 5 and the bottom plate 4 of the box body 1 are provided with lead-out rows 9 ; the coil 3 is wound on the cylindrical iron core 2 . It also includes several chassis slat pairs 10 and fans 11,
[0022] The bottom plate of the box body 1 is provided with diversion holes 12; the bottom frame slats 10 are uniform along the width direction on the bottom plate 4 of the box body, and there are guide holes between the two bottom frame slats in the bottom frame slats 10. Flow gap; the diversion gap matches the diversion hole 12;
[0023] The bottom frame slat pair 1...

The invention discloses a high-power active power filter reactor. The high-power active power filter reactor comprises a box body, barrel-shaped iron cores and coils, the high-power active power filter reactor further comprises multiple underframe batten pairs and draught fans, and flow guide holes are formed in a bottom plate of the box body; the underframe batten pairs are evenly arranged on the bottom plate of the box body in the width direction, and a flow guide gap is formed between every two adjacent underframe battens in the underframe batten pairs; the flow guide gaps are matched with the flow guide holes; the underframe batten pairs support the lower ends of the iron cores where the coils are wound, and the central holes of the iron cores are opposite to the flow guide holes in the bottom plate of the box body; multiple air inlets are formed in a cover plate of the box body, the draught fans are arranged on the cover plate of the box body, and air outlets of the draught fans are opposite to the air inlets. Due to the fact that the structure is adopted, heat of the iron cores can be dissipated quickly due to the arrangement of the draught fans, temperature rise can be effectively lowered, the service life can be effectively prolonged, and the working environment can be improved; noise can be lowered due to the use of the iron-silicon iron cores.
Description
technical field [0001] The invention relates to an active filter reactor, in particular to a high-power active filter reactor. Background technique [0002] The active filter device is a kind of power equipment that quickly tracks and filters the harmonic current generated in the power system. In recent years, with the maturity of the active filter technology, the power of the filter device is increasing. Traditional active filter reactors have large dimensions, high temperature, high noise, and relatively high cost. Contents of the invention [0003] The purpose of the present invention is to provide a high-power active filter reactor, which can effectively reduce the volume of the product and reduce the temperature rise and noise generated when the device is running. [0004] The present invention is realized in the following way: a high-power active filter reactor includes a box body, a cylindrical iron core and a coil, and the box body includes a bottom plate, a box b...
