Abstract
The utility model relates to an inner sealing triangular lead wire type electric furnace transformer, which comprises a transformer body. The utility model is characterized in that at least three groups of vertical junction copper bar assemblies are distributed on the wire outlet end of the transformer body, and the output end of each group of vertical junction copper bar assemblies is connected with the input end of a wiring sheet. Meanwhile, the output end of the wiring sheet is connected with a conductive rod assembly. Thereby, the vertical junction copper bar assemblies, the wiring sheets and the conductive rod assemblies form triangular wiring. The utility model omits the design of a transverse copper bar, and correspondingly reduces and saves the transformer oil and the copper materials. Through the triangular wiring formed among the vertical junction copper bar assemblies, the wiring sheets and the conductive rod assemblies, the heat radiation effect can be effectively improved.
Description
Technical field
The utility model relates to a kind of transformer, relates in particular to a kind of interior envelope triangular form lead type furnace transformer.
Background technology
The furnace transformer low-voltage lead is the path of drawing of transformer internal current, and the electric current in the transformer coil is drawn out to the fuel tank outside by low-voltage lead, outlet terminal, supplies with electric furnace work.Traditional low pressure internal interface is that D connects, conducting rod is drawn, the furnace transformer of side outlet, structure is: the every phase coil outlet of transformer is connected respectively to vertical confluence copper bar end to end, link by the connection copper bar of level then and finish D together and connect, weld lug plate on level connection copper bar, the other end of lug plate is received conducting rod.But, owing to adopted horizontal copper bar, poor radiation.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of interior envelope triangular form lead type furnace transformer is provided.
For realizing envelope triangular form lead type furnace transformer in the purpose of this utility model, include the transformer body, wherein: the leading-out terminal of transformer body is distributed with vertical confluence copper bar assembly; Described vertical confluence copper bar assembly has three groups at least, and each output of organizing vertical confluence copper bar assembly is connected into the input of lug plate, and the output of described lug plate is connected into the conducting rod assembly.
Further, above-mentioned interior envelope triangular form lead type furnace transformer, wherein, the output of described vertical confluence copper bar assembly is provided with four out splice going splices at least, all is connected with independently lug plate on described four out splice going splices.
Further, above-mentioned interior envelope triangular form lead type furnace transformer, wherein, described conducting rod assembly is a U type water-cooled conducting rod.
Again further, above-mentioned interior envelope triangular form lead type furnace transformer, wherein, described U type water-cooled conducting rod is provided with and patches joint.
Adopt technical solutions of the utility model, cancelled the design of horizontal copper bar, correspondingly reduce to have saved transformer oil and copper material.Simultaneously, rely on formation triangular shape wiring between vertical confluence copper bar assembly, lug plate and the conducting rod assembly, can effectively promote radiating effect.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of envelope triangular form lead type furnace transformer in this.
The implication of each Reference numeral is as follows among the figure:
1 transformer body, 2 vertical confluence copper bar assemblies
3 lug plates, 4 out splice going splices
5 U type water-cooled conducting rods 6 patch joint
Embodiment
Interior envelope triangular form lead type furnace transformer as shown in Figure 1, include the transformer body, its unusual part is: the leading-out terminal at the transformer body is distributed with vertical confluence copper bar assembly, this vertical confluence copper bar assembly has three groups at least, and each output of organizing vertical confluence copper bar assembly is connected into the input of lug plate.Simultaneously, the output of lug plate is connected into the conducting rod assembly.Thus, make between vertical confluence copper bar assembly, lug plate and the conducting rod assembly and to constitute the triangular shape wiring.
In conjunction with the utility model one preferred implementation, in order to help consolidating the transmission performance of triangular shape wiring, the output of the vertical confluence copper bar assembly that adopts is provided with four out splice going splices at least, all is connected with independently lug plate on described four out splice going splices.
Further, consider to produce bigger heat in the function of furnace transformer that in order effectively to cool off, the conducting rod assembly that the utility model adopted is a U type water-cooled conducting rod.Simultaneously,, be convenient to itself and smooth butt joint of U type water-cooled conducting rod, on U type water-cooled conducting rod, be provided with and patch joint for radiating requirements corresponding to vertical confluence copper bar assembly.Like this, the output of vertical confluence copper bar assembly cooperates as media by lug plate and patches joint and can be connected into U type water-cooled conducting rod, and both the D that finishes transformer by U type water-cooled conducting rod connect.
Be used for seeing in conjunction with actual making of the present utility model, the furnace transformer major function is to be used for smelting system energy is provided, its operating current is generally very big to be generally several kiloamperes to tens thousand of amperes, in order to guarantee that electric current passes through, the copper bar sectional area of the low-voltage lead of transformer is very big, forms very strong magnetic field around copper bar, and this magnetic field forms eddy current generation loss in the metallic conductor around, in order to reduce this loss, should guarantee enough distances from copper bar in transformer device structure raising middle flask span.The utility model has been cancelled loaded down with trivial details horizontal copper bar structure, and relies on formation triangular shape wiring between vertical confluence copper bar assembly, lug plate and the conducting rod assembly, has promoted the heat-dissipating distance between the vertical confluence copper bar assembly.
By above-mentioned character express and in conjunction with the accompanying drawings as can be seen, adopt the utility model after, cancelled the design of horizontal copper bar, correspondingly reduce to have saved transformer oil and copper material.Simultaneously, rely on formation triangular shape wiring between vertical confluence copper bar assembly, lug plate and the conducting rod assembly, can effectively promote radiating effect.
Certainly, more than only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
