Abstract
A transformer of a full constant power output energy-saving submerged arc furnace comprises a shell, an iron core, a high-voltage winding and a low-voltage winding, and is characterized in that the low-voltage winding adopts a paper-covered copper wire double-helix multi-parallel-winding concentric coil structure, the even cross transposition is realized, every two blocks with opposite current directions in a lead-out copper bar are arranged close to each other, and an insulating layer is inserted in the middle. The design parameters leave enough margin, no large oil duct needs to be left in the low-voltage winding, the axial and radial spaces in the iron core are effectively utilized, the magnetic leakage and load loss are reduced, the circulating current loss is avoided, the constant output power of all gears is ensured, the smelting process requirement is met, the energy-saving effect is obvious, and the iron loss and the copper loss are only 70% of the national standard respectively.
Description
The invention provides a kind of full constant power output transformer for energy-saving ore smelting furnace.
Use in the mine heat furnace smelting technology and require the reduction of transformer along with the secondary output voltage, the corresponding increase of output current promptly requires each gear power output constant.But because the secondary low-voltage winding of existing ore heat furnace transformer adopts the two cake concentric coil structures of conventional bare copper wire single-screw alternating expression coil or paper bag copper cash single-screw several paralleled conductor alternating expression coil or paper bag copper cash several paralleled conductor, all exist leakage field big, the impedance voltage height, circulation loss is big, big weak point takes up room, when the secondary output voltage is reduced to a certain degree, output current just can not be along with voltage reduces and continues to increase, promptly when low-voltage is exported, power output will diminish, thereby prolong smelting time, and thermal losses is big, the product quality of smelting is low, product electricity consumption unit consumption height.
The objective of the invention is in order to overcome above-mentioned weak point, and provide a kind of leakage field little, load loss is low, no circulation loss, and the secondary capacity is big, and energy-saving effect is remarkable, and all gears outputs all can reach the full constant power output transformer for energy-saving ore smelting furnace of rated capacity.
The object of the present invention is achieved like this: full constant power output transformer for energy-saving ore smelting furnace comprises shell, iron core, high pressure winding, low pressure winding, it is characterized in that the low pressure winding is for adopting paper bag copper cash double helix several paralleled conductor concentric coil structure, evenly coordinated transposition, whenever, divide 2 or 4 groups of parallel connections to draw mutually, the parallel connection of every component 2-3 section, the tail end of leading portion and the head end of back segment are in same axial horizontal level, winding is drawn per two close mutually arrangements of current opposite in direction in the copper bar, the middle insulating barrier that inserts.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a low pressure winding construction schematic diagram.
Now illustrated embodiment is made detailed description to the present invention in conjunction with the accompanying drawings.
With the HKSSP-6300/35 product is example, full constant power output transformer for energy-saving ore smelting furnace comprises shell 1, unshakable in one's determination 2, high pressure winding 3, low pressure winding 4, low pressure winding 4 is for 32 of employing paper bag flat type copper wire double helixs and around the concentric coil structure, evenly coordinated transposition, every conductor length is equated, whenever, divide 4 groups and coupling copper bar to draw mutually, 2 sections parallel connections of every component, the empty road of two intersegmental no big leakage fields, the tail end of leading portion and the head end of back segment are at same axial horizontal level, also need not to be provided with the empty road of big leakage field middle the adding between 5, two groups of the solid insulation pieces, chooses lower magnetic flux density B=1.5-1.68T and current density j=2.2-2.8A/mm in the design parameter
2Under the situation that does not increase axial and radial size, go out rated capacity 1.2-1.5 big capacity low pressure coil doubly in former space coiling that can only coiling rated capacity coil, the low pressure winding draw current opposite in direction in the copper bar per two mutually near arranging the middle insulating barrier 6 that inserts.After being inserted in high pressure winding 3, unshakable in one's determination 2 in the low pressure winding 4 respectively, install shell 1 again, each winding lead-out wire is connected on the binding post on the shell 1.
The present invention is owing to adopt above architecture advances, design parameter leaves enough leeway, the secondary low-voltage winding adopts the big capacity concentric coil of the double helix structure that need not stay big oil duct, evenly coordinated transposition, draw per two close mutually arrangements of current opposite in direction in the copper bar, effectively utilized interior axial and radial space unshakable in one's determination, reduce leakage field and load loss, no circulation loss, guarantee that all gear power outputs are constant, satisfy the requirement of smelting process to transformer, energy-saving effect is remarkable, and iron loss, copper loss only are respectively 70% of GB.
