電気エネルギーを伝達する媒介体であるバスバー（Ｂｕｓ ｂａｒ）は、発電所、大型建物、大型工場、大型デパート、地下鉄、新空港などで電流の容量が大きな大型送配電線、電気機器用導体、通信ケーブルなどの送電回路を構成し、一般的には主にケーブルが多く使われてきたが、最近ではバスバーが多様な長所を有しているため、ケーブルの代替品として多く使われている。 Bus bars, which are mediators that transmit electrical energy, are used in power plants, large buildings, large factories, large department stores, subways, new airports, etc., and have large current transmission and distribution lines, conductors for electrical equipment, and communications. Cables have been mainly used to form power transmission circuits such as cables, but recently, busbars have various advantages and are often used as a substitute for cables.
バスバーとケーブルを構造の面で比較してみると、類似点は導体と絶縁体を有するという点であるが、バスバーの最大の長所は同じ体積の導体でより多くの電気エネルギーを伝達できるという点である。したがって、大容量の配電システムにおいてバスバーの長所が認識されてその使用量が急速に増加しており、過去と比較して大容量の電気エネルギーを必要とする大型建物、大型工場、発電所、地下鉄などの需要が急増する趨勢に合わせて、バスバーは安全かつエネルギーの損失が少ないため現代の大容量送電システムに非常に適合した部品と認識されている。 Comparing busbars and cables in terms of structure, the similarities are that they have conductors and insulators, but the biggest advantage of busbars is that they can transfer more electrical energy with the same volume of conductors. Is. Therefore, the advantages of busbars in large-capacity distribution systems have been recognized and their usage is increasing rapidly, and large buildings, large factories, power plants, and subways that require large amounts of electrical energy compared to the past. Busbars are recognized as highly suitable parts for modern high-capacity power transmission systems because they are safe and have low energy loss in line with the rapidly increasing demand.
韓国登録特許第１０−０９７７０８９号（２０１０．０８．１３登録）にはバスバーおよびバスバー加工方法について記載されており、開示された技術によると、電気伝導体物質を押出成形して、側端部が
韓国登録特許第１０−０６０３０２１号（２００６．０７．１２登録）には銀コーティング層が添加された銅−アルミニウムクラッドバスバーおよびその製造方法について記載されている。開示された技術によると、電気エネルギーを伝達する通電用バスバーにおいて、前記バスバーの胴体は一定の長さと厚さのアルミニウムで形成され、前記アルミニウムの全体の表面に一定厚さの銀層が存在し、前記銀層の表面に一定厚さの銅層が存在する銅−銀−アルミニウム積層構造を含むことを特徴とする。 Korean Registered Patent No. 10-0603021 (registered on 2006.07.12) describes a copper-aluminum clad busbar to which a silver coating layer is added and a method for producing the same. According to the disclosed technology, in an energizing busbar that transmits electrical energy, the body of the busbar is made of aluminum of a certain length and thickness, and a silver layer of a certain thickness is present on the entire surface of the aluminum.

Otherwise, heat is generated when energized. Therefore, there is a problem that a cooler must be installed depending on the usage environment, and there is a high possibility that the aluminum material with a low melting point will melt due to the arc that can occur when energized, so the capacity of heavy electrical equipment or higher There is a problem that the device is not suitable.

以下、本発明の実施例に係るバスバー製造方法について図面を参照して詳細に説明する。 Hereinafter, the bus bar manufacturing method according to the embodiment of the present invention will be described in detail with reference to the drawings.

図１を参照すると、まず、移送装置を利用して第１電気伝導体の両端に第２電気伝導体をそれぞれ配置するＳ１００。 Referring to FIG. 1, first, S100 in which the second electric conductors are arranged at both ends of the first electric conductor by using a transfer device.
前述した段階Ｓ１００において、第１電気伝導体は棒状のアルミニウムであり、第２電気伝導体は棒状の銅であることを特徴とする。この時、電気接点が発生する部分に、相対的に電気伝導度が高く溶融点が高い銅素材を位置させることが好ましい。 In the above-mentioned step S100, the first electric conductor is rod-shaped aluminum, and the second electric conductor is rod-shaped copper. At this time, it is preferable to position a copper material having a relatively high electric conductivity and a high melting point at a portion where an electric contact is generated.
前述した段階Ｓ１００において、第１電気伝導体と第２電気伝導体は棒状であることが好ましいが、必要に応じて多様な形状および大きさで形成され得る。 In the above-mentioned step S100, the first electric conductor and the second electric conductor are preferably rod-shaped, but can be formed in various shapes and sizes as required.
前述した段階Ｓ１００において、第１電気伝導体の両端に第２電気伝導体が密着するように配置することができる。 In the step S100 described above, the second electric conductor can be arranged so as to be in close contact with both ends of the first electric conductor.
前述した段階Ｓ１００で配置された第１電気伝導体と第２電気伝導体の間を摩擦溶接機を利用して摩擦溶接するＳ２００。 S200 for friction welding between the first electric conductor and the second electric conductor arranged in the above-mentioned step S100 by using a friction welder.
摩擦溶接は、素材を１分に１６００−２２００ｒｐｍで回転させながら３−１０ｔｏｎの範囲で停止した素材の側面を加圧して接触面で１０００−１４００℃の摩擦熱が発生するようにし、その後、回転する素材を停止させるとともに接触面の方向で７−２０ｔｏｎの範囲で再度加圧して接触面を焼成変形させることによって溶接する方式である。 In friction welding, the material is rotated at 1600-2200 rpm per minute and the side surface of the material stopped in the range of 3-10 ton is pressurized so that frictional heat of 1000-1400 ° C is generated on the contact surface, and then the rotation is performed. It is a method of welding by stopping the material to be welded and pressurizing it again in the range of 7 to 20 tons in the direction of the contact surface to deform the contact surface by firing.
前述した段階Ｓ２００において、第１電気伝導体および第２電気伝導体を摩擦溶接機に装着して、回転力によって第１電気伝導体および第２電気伝導体を相互に逆方向に回転させ、第１電気伝導体と第２電気伝導体の密着面で発生する摩擦熱によって接合させることができる。これにより、互いに逆回転する第１電気伝導体と第２電気伝導体を密着させることによって、相対速度を第１電気伝導体と第２電気伝導体の回転速度を足し合わせた分くらいに増加させることができるだけでなく、外部からの制動力がない場合にも、正回転する第１電気伝導体の偶力と逆回転する第２電気伝導体の逆偶力が密着面で力の合成によって慣性が相殺されることによって制動されるようにする効果を提供することができる。 In the above-mentioned step S200, the first electric conductor and the second electric conductor are mounted on the friction welding machine, and the first electric conductor and the second electric conductor are rotated in opposite directions by the rotational force. It can be joined by the frictional heat generated on the contact surface between the 1 electric conductor and the 2nd electric conductor. As a result, the first electric conductor and the second electric conductor that rotate in opposite directions are brought into close contact with each other, so that the relative speed is increased by the sum of the rotation speeds of the first electric conductor and the second electric conductor. Not only can this be done, but even when there is no external braking force, the couple of the first electric conductor that rotates in the forward direction and the reverse couple of the second electric conductor that rotates in the opposite direction are inertial due to the combination of forces on the contact surface. Can provide the effect of being dampened by being offset.
前述した段階Ｓ２００において、第１電気伝導体および第２電気伝導体を相互に逆方向に既設定された回転速度（例えば、１分に１６００〜２２００ｒｐｍなど）で回転させることができ、第１電気伝導体と第２電気伝導体の密着面の摩擦熱が既設定された温度（例えば、第１電気伝導体および第２電気伝導体の融点など）に到達するまで回転させることができる。 In the above-mentioned step S200, the first electric conductor and the second electric conductor can be rotated in opposite directions at a preset rotation speed (for example, 1600 to 2200 rpm per minute), and the first electricity can be rotated. The frictional heat of the contact surface between the conductor and the second electric conductor can be rotated until it reaches a preset temperature (for example, the melting point of the first electric conductor and the second electric conductor).
前述した段階Ｓ２００において、第１電気伝導体と第２電気伝導体が密着した状態で相互に逆方向に回転する間に、密着面方向に７〜２０ｔｏｎ範囲で加圧力を提供することができる。 In the step S200 described above, while the first electric conductor and the second electric conductor are in close contact with each other and rotate in opposite directions, a pressing force can be provided in the range of 7 to 20 tons in the close contact surface direction.

前述した段階Ｓ３００において、摩擦溶接段階で摩擦溶接された第１電気伝導体と第２電気伝導体を圧延ロール装置を通過させて圧延成形することができる。この時、圧延成形を容易とするために第１電気伝導体と第２電気伝導体をあらかじめ加熱することができ、圧延成形を通じて第１電気伝導体と第２電気伝導体の角部分を丸く（ラウンディング）成形するなどの多様な形状に成形することができる。 In the step S300 described above, the first electric conductor and the second electric conductor that have been friction-welded in the friction welding step can be rolled and molded by passing through a rolling roll device. At this time, the first electric conductor and the second electric conductor can be preheated in order to facilitate rolling molding, and the corner portions of the first electric conductor and the second electric conductor are rounded through rolling molding ( It can be molded into various shapes such as rolling).
前述した段階Ｓ３００において、第１電気伝導体を平面の形態または３次元の形態に成形することができる。 In step S300 described above, the first electrical conductor can be molded into a planar or three-dimensional form.
前述した段階Ｓ３００で形成されたバスバーを所望の大きさで切断することができ、バスバーの両端をパンチングして端子連結のためのホールを形成することができる。 The bus bar formed in the above-mentioned step S300 can be cut to a desired size, and both ends of the bus bar can be punched to form a hole for connecting terminals.
前述したような段階を有するバスバー製造方法は、アルミニウムの両端に銅を摩擦溶接してバスバーを製造することによって、原価を節減し、重さを減らし、性能を向上させることができる。また、アルミニウムと銅間の結合力が堅固で高い強度を有するだけでなく、所望の大きさおよび形状のバスバーを製造することができる。 In the bus bar manufacturing method having the steps as described above, the cost can be reduced, the weight can be reduced, and the performance can be improved by friction-welding copper to both ends of aluminum to manufacture the bus bar. Moreover, not only the bonding force between aluminum and copper is firm and has high strength, but also a bus bar of a desired size and shape can be manufactured.

It is possible to prevent the bonding force between the electric conductors from becoming weak.

If the tempering temperature is less than 400 ° C., the effect is insufficient, and if the tempering temperature exceeds 500 ° C., the strength may decrease.
