Description
本發明有關一種組合變壓器結構，尤指一種可增加變壓器沿邊距離的組合變壓器結構。The invention relates to a combined transformer structure, in particular to a combined transformer structure which can increase the distance along the edge of the transformer.
以電力實施的各種電器產品中，變壓器通常扮演著轉換電力或隔離訊號的重要角色。然而，變壓器於通電工作的過程中會產生非常劇烈且明顯的電流變化以及電壓變化，因此，各國政府為了確保變壓器在通電工作過程中的安全性，針對變壓器制定了非常嚴苛的安全規範，如IEC/UL 60950-1：2000等安全規範。Among various electrical products implemented by electricity, transformers often play an important role in converting power or isolating signals. However, transformers generate very sharp and obvious current changes and voltage changes during power-on operation. Therefore, in order to ensure the safety of transformers during power-on operation, governments have established very strict safety regulations for transformers, such as Safety regulations such as IEC/UL 60950-1:2000.
就以IEC/UL 60950-1：2000來說，其規範了變壓器結構在安全實施的情況下應該具有的絕緣條件，如沿面距離(Creepage Distance)以及隔空距離(Clearcnce)等。其中，所稱的沿面距離又稱爬牆距離，若以兩線圈繞組的沿面距離進行解釋，其是指電氣橫越一線圈繞組至另一線圈繞組，所需經過變壓器線架表面的最短距離，也就是指電氣攀爬變壓器線架到另一線圈繞組所經過的變壓器表面最短距離，而安全規範中所制定的最少沿面距離是依據每一變壓器實施環境的不同而有相應的距離限制。為能符合安全規範對於沿面距離的限制，每一廠商無一不對此提出一個相應的結構，就如中華民國專利第I353613、I390558、M421580以及I338310號專利案。然而，現在廠商普遍是將變壓器線架一次側與二次側之間的間距加大，令沿邊距離可以延長，但這樣的舉動卻會導致變壓器線架的結構體積不斷的擴大，而無法微型化。除上述實施方式之外，如I338310號專利案所揭，其是利用一明顯向外突伸的第一絕緣部增加變壓器線架的沿邊距離，但第一絕緣部向外延伸的部分卻導致該變壓器線架無法以臥式實施，僅能以I338310號專利案所揭露的立式實施。In the case of IEC/UL 60950-1:2000, it specifies the insulation conditions that the transformer structure should have in the case of safe implementation, such as Creepage Distance and Clearance. Wherein, the so-called creeping distance is also called the creeping wall distance. If the creeping distance of the two coil windings is explained, it refers to the shortest distance that the electrical cross-winding of one coil winding to the other coil winding. It refers to the shortest distance of the surface of the transformer through which the electric climbing transformer wireframe passes to the other coil winding, and the minimum creeping distance specified in the safety specification has a corresponding distance limitation depending on the environment in which each transformer is implemented. In order to comply with the safety regulations for the creepage distance, each manufacturer has a corresponding structure, such as the patents of the Republic of China patents I353613, I390558, M421580 and I338310. However, manufacturers generally increase the distance between the primary side and the secondary side of the transformer wireframe, so that the distance along the edge can be extended, but such a move will lead to the continuous expansion of the structural volume of the transformer wireframe, and cannot be miniaturized. . In addition to the above embodiments, as disclosed in the I338310 patent, the first insulating portion that protrudes outwardly is used to increase the edge distance of the transformer wire frame, but the portion of the first insulating portion that extends outward causes the The transformer cable frame cannot be implemented in a horizontal manner and can only be implemented in the vertical form disclosed in the I338310 patent case.
本發明之主要目的，在於克服習用變壓器結構為了能夠符合安全規範中的絕緣條件限制，卻導致體積無法縮小或無法實施於多種態樣的問題。The main object of the present invention is to overcome the problem that the conventional transformer structure can not be reduced in size or can be implemented in various aspects in order to be able to comply with the insulation condition limitation in the safety specification.

In addition, the present invention can further provide a leakage inductance adjusting member 5 on the insulating support frame 2, and the leakage inductance adjusting member 5 includes a magnetic conductive member 51 buried in the leakage inductance adjusting member 5, The magnetic conductive element 51 affects the magnetic path of the primary coil 111 and the secondary coil 121, and changes the leakage inductance between the primary coil 111 and the secondary coil 121. To this end, the first insulating half-shell 21 has a first assembly portion 219 extending from the first auxiliary alignment portion 218 above the first engaging portion 216, and the second insulating half-shell 22 has a The second auxiliary alignment portion 228 extends from the second assembly portion 229 above the second engagement portion 226 , and the leakage inductance adjustment member 5 has two components respectively assembled to the first assembly portion 219 and the second assembly portion 229 . Upper track portion 52.
綜上所述，本發明該具較長沿邊距離的組合變壓器結構，包含有一主繞線架以及一裝設於該主繞線架上的絕緣支撐架。本發明該絕緣支撐架是由一第一絕緣半殼及一第二絕緣半殼組成，該第一、第二絕緣半殼分別具有一包覆該主繞線架的第一、第二包覆部，該第一、第二包覆部分別具有該第一、第二絕緣部以及分別從該第一、第二絕緣部延伸的第一、第二隔離部，該第一隔離部於一端具有一朝該第二隔離部延伸設置而覆蓋該第二隔離部的第一覆蓋部，該第二隔離部於受該第一覆蓋部所覆蓋的另一端具有一朝該第一隔離部方向延伸設置而覆蓋該第一隔離部的第二覆蓋部。藉此，以在該組合變壓器結構的體積不變情況下，增加該組合變壓器結構的沿面距離。In summary, the combined transformer structure with a longer edge distance includes a main bobbin and an insulating support frame mounted on the main bobbin. The insulating support frame of the present invention is composed of a first insulating half shell and a second insulating half shell, and the first and second insulating half shells respectively have a first and a second cladding covering the main winding frame The first and second covering portions respectively have the first and second insulating portions and the first and second separating portions respectively extending from the first and second insulating portions, the first insulating portion having one end at one end a first covering portion extending toward the second partition portion to cover the second partition portion, the second partition portion having a second cover portion extending from the first cover portion and extending toward the first partition portion And covering the second covering portion of the first partition. Thereby, the creeping distance of the combined transformer structure is increased under the condition that the volume of the combined transformer structure is constant.
