Description
Technical field
The utility model is specifically related to a kind of transformer copper aluminium syndeton.
Background technology
Transformer adopts wire to be coiled into solenoid form conventionally, the magnetic circuit therefore generally being formed by iron core, coil in transformer, and the lead-out wire in magnetic circuit is connected with binding post, forms integral product.Transformer is generally paper bag flat type copper wire coiling form, and wherein lead-out wire is directly flat type copper wire, uses for client.
But in the current transformer or inverter cabinet of electric power system, because cabinet dimensions design cost is limited conventionally, transformer need to be made into aluminium winding material sometimes; it when outlet, is exposed flat aluminium wire; or flat aluminium wire is directly accessed in terminal board, aluminium is oxidizable, easily produces corrosion; even in transformer case; because transformer is in uniform temperature and appropriate environment for a long time, can make aluminum steel corrosion, shorten the useful life of transformer; finally directly cause product rejection, even affect whole system.If it is aluminum steel that wiring is drawn in the outside of integrated transformers, connected while being copper cash when in use, between copper aluminium, can produce secondary electrically and chemical corrosion, cause aluminum steel to be corroded, this has made specified in more detail in GJB594-1988, and this kind of connection forbidden adopting.
The problems referred to above that run into for solving aluminium winding transformer, the way conventionally adopting is that the flat aluminium wire of winding being drawn in transformer inside is converted into copper strap wire, then enters terminal board, is connected with outside copper cash.Traditional implementation has following several: 1, adopt one section of aluminum bronze transition wire, this line one end is that the aluminium material other end is copper material, therefore aluminium material end can easier be realized welding with flat aluminium wire, same copper material end also can easier be realized and being welded to connect with copper strap wire, thereby realizes the conversion of flat aluminium wire to copper strap wire.This implementation is owing to co-existing in two interfaces in transformer inside, one is aluminium aluminium interface, and another is copper copper connecting, and the interface of material of the same race is more easily realized welding.2, another kind of implementation is in transformer, to adopt argon arc welding or tin immersion liquid welding directly flat aluminium wire to be connected with copper strap wire.As Chinese invention patent prospectus CN 101462189A discloses the welding method between a kind of aluminium enamel-covered wire and copper conductor of motor aluminium enamel-covered wire winding, it is all wrapped in the aluminium enamel-covered wire part after depainting on copper conductor link, and the copper aluminium enamel-covered wire part after being wound around is all immersed in tin liquor.
But there is following problems in said method: first: first method, because aluminium aluminium interface is oxidizable, affects the performance of transformer; The existence of two interfaces simultaneously increases pad, and transformer performance declines; Moreover aluminum bronze transition wire price is higher, has increased cost; Secondly: above two kinds of methods are because junction mechanical strength is poor, and welding procedure is more complicated, and after strenuous vibration, junction easily bends, and cause cracking or disconnect, impact is normally used.Last: the above two kinds of medium-term and long-term operation of method junctions easily produce chemical reaction, cause resistivity to increase, produce local overheating phenomenon.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of transformer copper aluminium syndeton, makes that it still has under long-time running state that cost is low, stable performance, well-set feature.
The technical solution of the utility model is: copper aluminium syndeton for a kind of transformer, comprise neat upper and lower overlapping copper strap wire and flat aluminium wire, and its outside comprises ring-type fixed connector, insulating tape winding layer and insulating sleeve successively; The two ends of insulating tape winding layer exceed ring-type fixed connector, and the copper flat aluminium wire part that is positioned at insulating tape winding layer inside is to remove the exposed copper flat aluminium wire of protective layer, and the copper flat aluminium wire part that is positioned at ring-type fixed connector inside is coated with scolding tin; Space between ring-type fixed connector inside and copper flat aluminium wire adopts scolding tin to fill.
Optimize, the specification of the diameter of ring-type fixed connector and length and copper flat aluminium wire lap adapts, and the bossing that is positioned at the upper and lower front and back of copper flat aluminium wire operates and the laminating of copper flat aluminium wire surface by compression.
Optimize, the material of described ring-type fixed connector adopts copper.
Optimize the outer fine material of silicon in described insulating sleeve adopts.
Optimize, described insulating sleeve is open type, and fixes with restraint zone in outside.
The beneficial effects of the utility model are, 1, the utility model adopts overlapping exposed copper flat aluminium wire and scolding tin is filled, only realize the conversion of flat aluminium wire to copper strap wire by having adopted a pad just, welding procedure is simple to operation, can ensure the stability after long-term use, and cost is lower; By adopting three layers of ring-type fixed connector, insulating tape winding layer and insulating sleeves to combine to play, strengthening is fixing, the effect of insulation protection; mechanical strength and the insulation property of junction are strengthened; after strenuous vibration, junction is also difficult for bending; can not cause cracking or disconnect; after long-term use, junction is also difficult for producing chemical reaction, can ensure normal use.2, by the employing ultrasonic wave method of attachment that goes between, instead of independent employing argon arc welding or copper-aluminium joint connecting lead wire, can make aluminum transformer lead-in wire connect as one, after being used under long-time running state, transformer still there is Stability Analysis of Structures, feature firmly, more reliable when use, safer.2, the structure that the utility model is fitted by the selection of ring-type fixed connector specification with copper flat aluminium wire surface, dwindle the space between ring-type fixed connector and copper flat aluminium wire, simplify welding procedure, improved the welding quality connecting, further strengthened the fastness at tie point place.3, the material of ring-type fixed connector adopts copper, has strengthened the fixed performance of ring-type fixed connector; 4, insulating sleeve adopts the outer fine material of interior silicon, effectively raises the safe and reliable insulating effect of aluminum transformer junction, and reduces costs.5, insulating sleeve of the present utility model passes through to adopt open type, and fixes with restraint zone in outside, has further strengthened the fixed performance of junction.
In sum, the transformer that the utility model provides has connection, insulate, fixes, reduces costs quadruple effect by copper aluminium syndeton, has multifunctionality.
