Two, break through the confinement of conventional planar structure, adopt three identical semi-circular section volume iron cores, be combined into equilateral three-dimensional tri-phase iron core, make tri-phase iron core magnetic circuit full symmetric, magnetic resistance greatly reduces, exciting curent, no-load loss significantly reduce, and become running noises less, the energy-efficient triangle volume iron core new product that structure is more compact.Therefore, of the present invention have the Regulatable reactor of carrying to be widely used in the economize on electricity product of electrical network and distribution system online, and particularly the distribution system of voltage levels high power capacity has more unique advantage.Owing to thering is unique adjustable function of not power-off online, be also widely used in power electronics, wind-powered electricity generation, photovoltaic and intelligent grid.
Three, save material, reduce costs.Stereo-triangular wound iron core rod cross section in the present invention is accurate polygon, cross section activity coefficient can reach 0.95～0.96, and the stem cross section of traditional folded iron core is notch cuttype, cross section activity coefficient is only 0.89～0.925, therefore the in the situation that of same cross-sectional area, stereo-triangular wound iron core in the present invention, than the average turn length 2～3% of the heart line bag of the folded iron core of tradition, is namely saved copper material 2～3%, saves silicon strip approximately 15%.
Four, improve performance, reduce the wastage.Because the average magnetic circuit of stereo-triangular wound iron core of the present invention is shorter than the average magnetic circuit of traditional folded iron core, the weight of the folded iron core that therefore weight ratio of stereo-triangular wound iron core of the present invention is traditional is obviously light.In the situation that technological coefficient is identical, the no-load loss of stereo-triangular wound iron core of the present invention is just obviously low, and performance is good.Three-dimensional winding iron core reactor of the present invention with the comparison of capacity lamination reactor, save silicon steel sheet consumption approximately 20%, copper consumption 2～3%, no-load current declines 70%, noise decline 5dB (A)～9dB (A).
Five, reduce noise.Stereo-triangular wound iron core of the present invention is to be reeled and form successively by several trapezoidal material strips, tightr between silicon strip, the magnetic conduction direction of silicon strip and the magnetic circuit direction of iron core are in full accord, during work, vibrate little, and can solve the noise that traditional folded iron core sends because magnetic circuit is discontinuous, can make reducing noise to bottom line, general comparable folded appendiron core transformer reduces by 8～15dB (A), substantially reaches mute state.
Six, three-phase equilibrium.Because three stems of traditional folded iron core are planar alignment, make like this length of magnetic path of three stems inconsistent: the length of magnetic path of middle stem is the shortest, the magnetic circuit of two side columns is longer, the average length of magnetic path of two side columns is longer more than 20% than the average length of magnetic path of center pillar, thereby cause the loss difference of three stems larger, center pillar loss is minimum, and the loss of two side columns is larger, causes three-phase imbalance.And stereo-triangular wound iron core in the present invention is to be put together by three identical single frames, three stems are triangular arranged, and the length of magnetic path of three stems is in full accord, and the shortest, and three stem losses are consistent, thereby three-phase equilibrium.
