Description

本考案は、小型リアクトルにおいて、性能の安定化、並びに製造性の向上を図ったバイパス磁路式リアクトルに関するものである。   The present invention relates to a bypass magnetic path type reactor in which performance is stabilized and manufacturability is improved in a small reactor.

小型リアクトルは、成型ボビンにコイルを巻装して構成し、このコイルにE形珪素鋼板を多数積層して構成されている。   A small reactor is formed by winding a coil around a molded bobbin, and a large number of E-shaped silicon steel plates are laminated on the coil.

この種のリアクトルは、漏洩磁束による過電流損失が発生するので、この損失を少なくする考案の提供が望まれている。   Since this type of reactor causes an overcurrent loss due to leakage magnetic flux, provision of a device for reducing this loss is desired.

特許文献1の公報には、漏洩磁束を低減することができるリアクトルの発明が記載されている。   Patent Document 1 discloses an invention of a reactor that can reduce leakage magnetic flux.

特開2006−100513号公報JP 2006-100513 A

小型リアクトルは、成型ボビンにコイルを巻装して校正紙、このコイルにE形珪素鋼板を多数積層して構成される。
又、E型鋼板の積厚は使用ボビンの内径寸法により決まり、I型鋼板は相当する成型品の金具の寸法に合わせて鋼板を挿入するように構成されている。
従来知られている図4に示す小型リアクトルによれば、I型鋼板を固定する金具9の寸法は鋼板の型式により決まり、組立用の金具9は積層されたE型鋼板及びI形鋼板が容易に挿入出来るように若干(0.5mm程度)大きく出来ている為、E型鋼板の積層寸法L2とI型鋼板の積厚寸法L1が合わないものであった。
A small reactor is formed by winding a coil around a molded bobbin and proofing paper, and laminating a number of E-shaped silicon steel plates on the coil.
In addition, the thickness of the E-type steel plate is determined by the inner diameter of the bobbin used, and the I-type steel plate is configured to insert the steel plate in accordance with the size of the fitting of the corresponding molded product.
According to the conventionally known small reactor shown in FIG. 4, the size of the metal fitting 9 for fixing the I-shaped steel plate is determined by the type of the steel plate, and the assembled metal fitting 9 is easy to be a laminated E-shaped steel plate and I-shaped steel plate. Therefore, the stacking dimension L2 of the E-type steel sheet and the stacking dimension L1 of the I-type steel sheet do not match.

全体を組立てる場合は、E型鋼板とI型鋼板の接合部に非磁性材を用いて間隙を設け、金具を使用して全体の組立作業やインダクタンス値の調整を行うようになされている。
しかし、「組立作業」や「インダクタンス値の調整」は金具を使用しなければできなかった。
更にボビンの形状によりI形鋼板がボビンの角部に接触し、鋼板間隙を一定以下にするのは困難であった。又、ワニス処理等を行った場合、ワニスの侵入によりインダクタンス値が変化してしまい再調整等の必要性が生じていた。
When the whole is assembled, a gap is formed by using a non-magnetic material at the joint between the E-type steel plate and the I-type steel plate, and the whole assembly operation and adjustment of the inductance value are performed using metal fittings.
However, “assembly work” and “adjustment of inductance value” could not be performed without using metal fittings.
Further, the I-shaped steel plate contacts the corner of the bobbin due to the shape of the bobbin, and it is difficult to keep the steel plate gap below a certain level. Further, when varnish treatment or the like is performed, the inductance value changes due to the penetration of the varnish, and the need for readjustment or the like has arisen.

前記特許文献1に記載された発明は、漏洩磁束を低減するために、巻鉄心からなる継鉄心と、この継鉄心に直行するように配置され、積層加工された積鉄心を設けたものであるが、構成が複雑で、加工や組み立て性においても、未だ充全ものとはいえないものである。
又、特許文献1の場合は鋼板の間隙用絶縁材の挿入がコイル内部の中間となる為、間隙調製用絶縁材を正確に挿入する事が困難であった。
本考案は、従来一般に知られている小型リアクトルや、特許文献1に記載された発明の課題を解決し、簡単な構成で、漏洩磁束による損失を大幅に低減することができるバイパス磁路式リアクトルを提供することを目的としてなされたものである。
The invention described in Patent Document 1 is provided with a yoke core made of a wound iron core and a stacked iron core that is arranged so as to be orthogonal to the yoke core in order to reduce leakage magnetic flux. However, the structure is complicated, and the processing and assemblability are not yet satisfactory.
In the case of Patent Document 1, since the insertion of the insulating material for gaps in the steel plate is in the middle of the coil, it is difficult to accurately insert the insulating material for gap adjustment.
The present invention solves the problems of the conventionally known small-sized reactor and the invention described in Patent Document 1, and is a bypass magnetic path type reactor that can greatly reduce loss due to leakage magnetic flux with a simple configuration. It was made for the purpose of providing.

本考案は、前記目的を達成するために、E型に型抜きされた磁性鋼板を積層して主磁路鉄心を形成するバイパス磁路式リアクトルにおいて、この主磁路鉄心の両側のE型鋼板を、他のE型鋼板と反対方向に積層してバイパス磁路式リアクトルを構成したものである。
又、前記両側のE型鋼板の開放方向にI型鋼板を配置してバイパス磁路式リアクトルを構成したものである。
In order to achieve the above object, the present invention provides a bypass magnetic path type reactor in which magnetic steel sheets cut into E-shape are laminated to form a main magnetic path core, and E-shaped steel sheets on both sides of the main magnetic path core. Are laminated in a direction opposite to that of other E-shaped steel plates to constitute a bypass magnetic path type reactor.
Further, a bypass magnetic path type reactor is configured by arranging I-type steel plates in the opening direction of the E-type steel plates on both sides.

補足説明すれば、E形鋼板の挿入方法により、バイパス磁路を設ける本考案は、両サイドのE型鋼板の挿入方向を逆方向にする事によりI型鋼板の固定が容易になり、鋼板の積厚も一定にする事が可能で、更に、I型鋼板の固定も容易になり、鋼板間隙も任意に調整することが出来る。
又、間隙調整後は鋼板の外周を粘着テ−プ7等にて固定することにより、コイル、鋼板、間隙調整材が一体化されて固定される。調整後は、調整値を再確認し、金具にて機械的に固定して、ワニス処理を施し、本考案のバイパス磁路式リアクトルを得ることができる。
If it explains supplementarily, this invention which provides a bypass magnetic path by the insertion method of an E-shaped steel plate makes it easy to fix an I-shaped steel plate by reversing the insertion direction of the E-shaped steel plates on both sides. The stacking thickness can be made constant, the I-type steel plate can be easily fixed, and the gap between the steel plates can be arbitrarily adjusted.
Further, after the gap adjustment, the outer periphery of the steel plate is fixed with an adhesive tape 7 or the like, so that the coil, the steel plate, and the gap adjusting material are integrated and fixed. After the adjustment, the adjustment value can be reconfirmed, mechanically fixed with metal fittings, varnished, and the bypass magnetic path reactor of the present invention can be obtained.

前述したように、本考案によれば、簡単な構成で、漏洩磁束による損失を大幅に低減することができるバイパス磁路式リアクトルを提供することができるものである。   As described above, according to the present invention, it is possible to provide a bypass magnetic path type reactor that can significantly reduce loss due to leakage magnetic flux with a simple configuration.

又、金具を使用せずにインダクタンス値の調整が出来るので、調整作業が容易になり任意の間隙に調整出来るので調整範囲が拡大する。   In addition, since the inductance value can be adjusted without using a metal fitting, the adjustment work becomes easy and the gap can be adjusted to an arbitrary gap, so that the adjustment range is expanded.

性能的にも本考案の構成とすると、電圧−電流比の直線性を保ちながら、インダクタンス値を、従来に比較して大きな値に調整できるものである。   In terms of performance, if the configuration of the present invention is used, the inductance value can be adjusted to a larger value than the conventional one while maintaining the linearity of the voltage-current ratio.

It has been made as a basic configuration to facilitate.

尚、両サイドのバイパス鋼板の量により特性的に直線性が損なわれたりすることがあるので、特性に合わせて最適な量とすることが望まれる。   In addition, since linearity may be impaired characteristically depending on the amount of the bypass steel plates on both sides, it is desirable to set the optimum amount in accordance with the characteristics.
