Abstract
The utility model provides a multi-loop DC transformer for smelting, which aims at eliminating reactance loss and eddy loss. The transformer comprises two groups of iron cores which are wound by coils, wherein two ends of each coil are respectively connected in series with rectifying elements; and the two ends of each group of coils are connected together, and the DC is output to an arc furnace through a short network. According to the transformer provided by the utility model, multi-loop DC is adopted, the unit sectional area of a conductor winding is effectively reduced, so that the shortcoming of conductor skin effect is overcome to the utmost, and the eddy loss is effectively reduced; a multi-loop DC power supply smelting method is adopted to suppress the generation of harmonic waves and purify the power supply quality of the power network; as the rectifying elements are directly mounted on low-voltage terminals, a separated rectifier cabinet is saved, field installation space is greatly reduced and the equipment investment cost is also reduced; and moreover, the cooling system of the rectifying elements can be omitted, and the rectifying elements and the transformer can share one cooling system.
Description
Technical field
The utility model relates to a kind of transformer, especially a kind of multiloop direct current smelting transformer.
Background technology
The short net copper bar (or copper pipe) of the hot stove in common interchange ore deposit has kelvin effect, eddy current is arranged, reactance is arranged; Change can produce the loss of voltage that eddy current loss, reactance are brought so; And commutator transformer uses in the middle of smelting, and these problems are all solved, and has only to exchange and smelts the resistance loss that also exists.And transformer is before diauxic shift is not direct current; Conductor in the coil also has kelvin effect and vortex phenomenon; For reduce loss as far as possible; We adopt multiloop direct current smelting transformer (like figure), make it reach the output of 12 pulse wave formulas, 24 pulse waves, are specially adapted to the smelting production of vast capacity (more than the 30000KVA).
The utility model content
The purpose of the utility model provides a kind of multiloop direct current smelting transformer of eliminating reactance loss and eddy current loss.
Realize the multiloop direct current smelting transformer of the utility model purpose, comprise two groups of iron cores, every group of iron core comprises the iron core more than three, is tied with coil on the said iron core, and the two ends of said each coil are in series with rectifier cell respectively; The two ends of every group coil are connected to together, export to the hot stove in said ore deposit through short net direct current.
Said two groups of iron cores are separately positioned on the both sides of the hot stove in said ore deposit.
Said two groups of iron cores are arranged on a side of the hot stove in said ore deposit, and the input of said two groups of iron cores links to each other.
The beneficial effect of the multiloop direct current smelting transformer of the utility model is: reduce the unit cross-sectional area of conductor winding effectively, overcome this shortcoming of conductor kelvin effect the biglyyest, effectively reduce eddy current loss; Multiloop direct current supply smelting process has suppressed the generation of harmonic wave, has purified the power supply quality of electrical network; Saved an independent rectifier cabinet, only needed a small-sized control cubicle to get final product, practiced thrift the place installing space greatly and reduced the equipment input cost.

Embodiment
Embodiment 1: as shown in Figure 1, the multiloop direct current smelting transformer of the utility model comprises two groups of iron cores, and every group of iron core comprises the iron core 1 more than three, is tied with coil 2 on the said iron core 1, and the two ends of said each coil 2 are in series with rectifier cell 3 respectively; The two ends of every group coil 2 are connected to together, export to the hot stove 4 in said ore deposit through short net direct current.Said two groups of iron cores are separately positioned on the both sides of the hot stove 4 in said ore deposit.
Embodiment: 2: as shown in Figure 2, the multiloop direct current smelting transformer of the utility model comprises two groups of iron cores, and every group of iron core comprises the iron core 1 more than three, is tied with coil 2 on the said iron core 1, and the two ends of said each coil 2 are in series with rectifier cell 3 respectively; The two ends of every group coil 2 are connected to together, export to the hot stove 4 in said ore deposit through short net direct current.Said two groups of iron cores are arranged on a side of the hot stove 4 in said ore deposit, and the input of said two groups of iron cores links to each other.
The advantage of the multiloop direct current smelting transformer of the utility model is following: the utility model can be practiced thrift the installing space of a rectifier cabinet, reduces the mounting distance of 1500MM, has just reduced resistance loss.Many transformers of multiloop can reduce negative loss 5-8% than separate unit with the smelting of capacity.Because system is direct current output, with the reactance of existing technology and the shorter mesh portions of apparatus in comparison be zero, eddy current loss is zero, the synthesis energy saving effect can reach 5-8%.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection range that claims of the utility model confirm.
