Description
本発明は、オンロードタップ切換器（ＯＬＴＣ、ｏｎ−Ｌｏａｄ Ｔａｐ Ｃｈａｎｇｅｒ）に関し、具体的には永久磁石により駆動されるオンロードタップ切換器に関する。 The present invention relates to an on-road tap changer (OLTC), and more particularly to an on-road tap changer driven by a permanent magnet.
変圧器は、一つのタップから他の一つのタップに切換えることによって変圧器の高電圧側のコイルの有効巻数を変え、電圧調整の目的を実現する。オンロードタップ切換器は切換開閉器によって負荷電流を切換え、高速機構は切換開閉器の動力の源となっている。現在、高速機構は主にばねによるエネルギー放出装置を用いるが、ばねの信頼性は低く、一度主なばねが損傷されると高速機構全体が使えなくなる。使用時間が長くなることにつれて、ばねの弾性性能が段々悪くなるかばね自体が断裂される可能性があるため、深刻の結果を招いてしまう。 The transformer changes the effective number of turns of the coil on the high voltage side of the transformer by switching from one tap to another tap, thereby realizing the purpose of voltage regulation. The on-load tap switch switches the load current by a switching switch, and the high-speed mechanism is a source of power for the switching switch. At present, the high-speed mechanism mainly uses an energy release device by a spring, but the reliability of the spring is low, and once the main spring is damaged, the entire high-speed mechanism cannot be used. As the usage time increases, the elastic performance of the spring gradually deteriorates or the spring itself may be torn off, resulting in serious consequences.
本発明は、上記問題に鑑みてなされたものであり、高速機構を必要とせず、可動接点が直接動作し、迅速かつ信頼性が高く、使用寿命の長い永久磁石駆動のオンロードタップ切換器を提供することを目的とする。 The present invention has been made in view of the above problems, and does not require a high-speed mechanism, a movable contact operates directly, a quick, reliable, long-life permanent magnet drive on-load tap changer. The purpose is to provide.
上記目的を達成するための本発明に係る永久磁石駆動のオンロードタップ切換器は、切換開閉器回路を含み、該切換開閉器回路は、構造が同じである奇数タップ切換回路および偶数タップ切換回路を有し、前記奇数タップ切換回路および前記偶数タップ切換回路は、いずれも動作接点、過渡接点、および動作接点と過渡接点との間の過渡抵抗を備えており、前記動作接点および過渡接点は、いずれも一つの可動接点に直面しており、各可動接点は互いに並列に接続され、各々の可動接点には可動接点永久磁石の一端が接続されており、可動接点永久磁石の他端は可動接点駆動機構に直面している。前記可動接点駆動機構は、移動により可動接点永久磁石に対する作用力を変え、可動接点と、動作接点および過渡接点とを接触または分離させる移動永久磁石を含む。移動永久磁石を移動させることにより、移動永久磁石の可動接点永久磁石に作用する力を変え、可動接点と、動作接点および過渡接点との接触、分離を実現する。移動永久磁石と可動接点永久磁石との同じ種類の磁極が近づく場合、移動永久磁石は可動接点永久磁石に対して反発する力が働き、可動接点と動作接点／過渡接点とは接触する。一方、移動永久磁石と可動接点永久磁石との異なる種類の磁極が近づく場合、移動永久磁石は可動接点永久磁石に対して引き合う力が働き、可動接点と動作接点／過渡接点とは分離する。 In order to achieve the above object, a permanent magnet drive on-load tap changer according to the present invention includes a switching switch circuit, and the switching switch circuit has an odd-numbered tap switching circuit and an even-numbered tap switching circuit having the same structure.

The movable contact drive mechanism includes a moving permanent magnet that changes an acting force on the movable contact permanent magnet by movement to contact or separate the movable contact from the operating contact and the transient contact. By moving the moving permanent magnet, the force acting on the moving contact permanent magnet of the moving permanent magnet is changed, and contact and separation between the moving contact, the operating contact and the transient contact are realized. When the same kind of magnetic poles of the moving permanent magnet and the movable contact permanent magnet approach each other, the moving permanent magnet exerts a repulsive force against the movable contact permanent magnet, and the movable contact and the operating / transient contact come into contact with each other. On the other hand, when different types of magnetic poles of the moving permanent magnet and the movable contact permanent magnet approach each other, the moving permanent magnet is attracted to the movable contact permanent magnet, and the movable contact and the operating contact / transient contact are separated.
前記移動永久磁石は、間隔をおいて並列に設けられている複数の永久磁石により構成され、隣り合う永久磁石の同じ側の磁極は異なる。これによって、可動接点の動作に対する制御が便利になる。 The moving permanent magnet is composed of a plurality of permanent magnets arranged in parallel at intervals, and the magnetic poles on the same side of adjacent permanent magnets are different. This makes it convenient to control the operation of the movable contact.
可動接点は可動接点永久磁石の同じ種類の磁極側に接続され、可動接点永久磁石の同じ種類の磁極側とは可動接点永久磁石の可動接点駆動機構に直面している磁極側である。これによって、移動永久磁石の設計や製造が便利になるとともに、可動接点永久磁石が受ける力の調整も便宜になる。 The movable contact is connected to the same type of magnetic pole side of the movable contact permanent magnet, and the same type of magnetic pole side of the movable contact permanent magnet is the magnetic pole side facing the movable contact driving mechanism of the movable contact permanent magnet. This makes it convenient to design and manufacture the moving permanent magnet and also adjusts the force received by the movable contact permanent magnet.

図１に示すように、移動永久磁石の上側がＮ極である永久磁石を可動接点Ｄ１に直面させておくと、可動接点Ｄ１に対して反発する力が働き、可動接点Ｄ１を動作接点Ｋ１に接触させる。一方、上側がＳ極である永久磁石は可動接点Ｄ２、Ｄ３、Ｄ４に直面され、該三つの可動接点に対して引き合う力が働き、可動接点Ｄ２、Ｄ３、Ｄ４をそれぞれ直面している過渡接点ｋ１、ｋ２および動作接点Ｋ２と分離させる。これによって、タップＩとの接続が実現される。続いて、移動永久磁石を右側に移動させ、図２に示すように、上側がＮ極である永久磁石を同時に可動接点Ｄ１、Ｄ２に直面させておくと、可動接点Ｄ２も上方向に向いて推されて過渡接点ｋ１と接触する。一方、上側がＳ極である永久磁石は可動接点Ｄ３、Ｄ４のみに直面され、引き続いて動作接点と過渡接点とが分離されている状態である。続いて、移動永久磁石をさらに右側に移動させ、図３に示すように、上側がＮ極である永久磁石を可動接点Ｄ２、Ｄ３に直面させておくと、可動接点Ｄ２、Ｄ３はそれぞれが直面している過渡接点と接触される。一方、左側の上側がＳ極の永久磁石は可動接点Ｄ１に直面され、引き合う力の作用のもと、可動接点Ｄ１と動作接点Ｋ１とは分離される。この際、右側の上側がＳ極である永久磁石は依然として可動接点Ｄ４に直面され可動接点Ｄ４と動作接点Ｋ２とを分離させる。最後に、引き続いて移動永久磁石を右側に移動させ、同様の原理により、図５に示すようになるまで、可動接点Ｄ１、Ｄ２、Ｄ３を対応する動作接点または過渡接点と分離させ、可動接点Ｄ４を動作接点Ｋ２と接触させて、タップＩからタップＩＩへの切換えを完成する。
