Description

本考案は、例えば一次側に付与された高圧パルスを昇圧して、二次側にその高 圧パルスを誘起する高圧パルストランスに使用されるコイル装置に関する。 The present invention relates to a coil device used in a high-voltage pulse transformer that boosts a high-voltage pulse applied to the primary side and induces the high-voltage pulse on the secondary side, for example.
【０００２】[0002]
図３に示すような用途に使用される高圧パルストランスＴの回路の一次側端子 ａ−ａ′間に例えば図４のような高圧パルスを印可すると、二次側端子ｂ−ｂ′ 間にはこの高圧パルスが昇圧されて図５のようなパルスが発生する。このような 機能を持つ回路の一例を図６に示している。 When a high-voltage pulse as shown in FIG. 4 is applied between the primary side terminals aa 'of the circuit of the high-voltage pulse transformer T used for the application shown in FIG. 3, the secondary side terminals b-b' are connected. This high voltage pulse is boosted to generate a pulse as shown in FIG. An example of a circuit having such a function is shown in FIG.
【０００３】 この図６の回路の動作状態について説明する。駆動回路ＡのコンデンサＣに電 荷が徐々に充電されてきて、この充電電圧がギヤップＧ−Ｇ′間の放電開始電圧 に達すると、このギヤップＧ−Ｇ′間で絶縁破壊現象を起こし、コンデンサＣに 蓄積された電荷は、高圧パルストランスＴの一次巻線Ｌ1 を介して放電する。こ のとき、高圧パルストランスＴの一次側には図４のような電圧波形の高圧パルス が発生する。この高圧パルスが、高圧パルストランスＴにより昇圧されて二次側 には図５のような電圧波形の高圧パルスが得られる。ここでコンデンサＣの両端 電圧及び一次側電圧を図７に示している。The operating state of the circuit of FIG. 6 will be described. When the capacitor C of the drive circuit A is gradually charged with the charge and the charging voltage reaches the discharge start voltage between the gaps G-G ', a dielectric breakdown phenomenon occurs between the gaps G-G' and the capacitor C The electric charge accumulated in C is discharged through the primary winding L 1 of the high voltage pulse transformer T. At this time, a high voltage pulse having a voltage waveform as shown in FIG. 4 is generated on the primary side of the high voltage pulse transformer T. This high-voltage pulse is boosted by the high-voltage pulse transformer T, and a high-voltage pulse having a voltage waveform as shown in FIG. 5 is obtained on the secondary side. Here, the voltage across the capacitor C and the voltage on the primary side are shown in FIG.
【０００４】 図８には、このような働きをする高圧パルストランスのコイル装置の一例を示 している。この高圧パルストランスでは、コアＲの外周に於ける一次巻線Ｌ1 を 有する一次ボビンＱ1 の外側の二次ボビンＱ2 に巻回されている巻線Ｌ2 は、巻 線間に生ずる約５００Ｖ以上の電位差に対する耐圧を付与する必要がある。その ために隣接する巻線間には或る程度の隙間を持たせなければならないので、二次 側巻線Ｌ2 は、二次ボビンＱ2 に穿設された角形の溝Ｍ内に埋設しながら巻線を ボビンに巻回している。FIG. 8 shows an example of a coil device of a high-voltage pulse transformer that performs such a function. In this high-voltage pulse transformer, the winding L 2 wound around the secondary bobbin Q 2 outside the primary bobbin Q 1 having the primary winding L 1 on the outer periphery of the core R is generated between windings. It is necessary to provide withstand voltage against a potential difference of 500 V or more. For this reason, a certain gap must be provided between the adjacent windings, so that the secondary winding L 2 is embedded in the rectangular groove M formed in the secondary bobbin Q 2. While winding the winding on a bobbin.
【０００５】[0005]
そこで図９に示すようにボビンＮに穿設された角形の溝Ｍ内に埋設しながら巻 線Ｌを、そのボビンＮに巻回するのであるが、ボビンＮの溝Ｍの加工上の問題か ら巻線Ｌのコイルターン間隔以上の溝間寸法ｄ1 の壁体Ｏが必要であり、且つ巻 線工程上の問題から溝Ｍ内の巻線Ｌとの間には（ｄ2 ＋ｄ3 ）の隙間が必要であ る。そしてボビンＮの溝Ｍの加工上の問題から隣接する角形の溝Ｍ、Ｍ間の壁体 Ｏの幅ｄ1 は、耐圧確保の観点からも必要な寸法となる。このような理由から従 来のコイル装置では、その軸方向の長さｌを短縮することができず、従ってコイ ル装置全体を小型に設計できない問題点がある。Therefore, as shown in FIG. 9, the winding L is wound around the bobbin N while being embedded in the rectangular groove M formed in the bobbin N. Is this a problem in processing the groove M of the bobbin N? A wall body O having a groove dimension d 1 which is equal to or larger than the coil turn interval of the winding L, and (d 2 + d 3 ) between the winding L and the winding L in the groove M due to a problem in the winding process. Gap is required. From the problem of processing the groove M of the bobbin N, the width d 1 of the wall O between the adjacent rectangular grooves M, M is a necessary dimension from the viewpoint of ensuring the pressure resistance. For this reason, the conventional coil device has a problem in that the axial length l cannot be shortened, so that the coil device cannot be designed as a whole.
【０００６】 本考案は前記のような問題点に鑑み、その目的とするところは、ボビンの溝加 工工作を容易にできるばかりでなく、ボビンの軸方向の長さを短縮できて、コイ ル装置全体を小型化することにある。The present invention has been made in view of the above problems, and an object of the present invention is not only to facilitate the groove machining of the bobbin, but also to shorten the axial length of the bobbin, and It is to downsize the entire device.

本考案の高圧パルストランスのコイル装置は、底部両側の少なくとも一側に傾 斜面を有する溝をボビン外周に設けて、その隣接する溝相互間に山型形状の壁体 を形成し、その溝内に嵌合しながら巻線を前記ボビンに巻回することにより、前 記目的を達成することができた。 The coil device of the high-voltage pulse transformer of the present invention is provided with a groove having a slanted surface on at least one side on both sides of the bottom portion on the outer circumference of the bobbin, and a mountain-shaped wall body is formed between the adjacent grooves. By winding the winding wire around the bobbin while fitting into, the above-mentioned object could be achieved.

次に本考案の作用について述べる。底部両側の少なくとも一側に傾斜面を有す る溝をボビン外周に設け、その隣接する溝相互間に山型形状の壁体を形成するこ とにより、ボビンの溝の加工上取り除くことができなかった溝相互間に位置する 壁体の不必要な箇所を省略して、巻線相互間の耐圧を確保するために必要な絶縁 距離を充分に取ると共に、絶縁性能を低下させることなく、而もコイル装置全体 の軸方向の長さを短縮する。 Next, the operation of the present invention will be described. By forming a groove with an inclined surface on at least one side on both sides of the bottom part on the outer circumference of the bobbin, and forming a mountain-shaped wall between the adjacent grooves, it is possible to remove it for machining the bobbin groove. The unnecessary wall portions located between the grooves, which were not provided, are omitted to ensure a sufficient insulation distance for securing the withstand voltage between the windings, and the insulation performance is not deteriorated. Also reduces the axial length of the entire coil system.

It is explanatory drawing which compares with. In the case of the conventional rectangular groove 2'of FIG. 2B, the width of the wall 8'between the windings 7 depends on the bobbin machining problem, and the width between the windings 7'requires the required insulation between the windings 7. It is much larger than the distance. In other words, the width of the wall 8'includes the shaded portion x 1 of FIG. 2B, so that this portion is an excessive portion with respect to the pressure resistance performance of the entire coil device, and therefore the coil device is not. The overall axial length cannot be reduced.

By omitting it, a sufficient insulation distance can be secured to secure the withstand voltage between the windings 7, and therefore the insulation performance does not deteriorate, and the axial length of the entire coil device is shortened. can do.
【００１２】 上記は図１の（Ａ）（Ｂ）（Ｃ）に示す溝に共通する利点であるが、（Ｃ）に 示す溝は巻線間の壁体の根元部分の幅を大きく取ることができることになり、他 の（Ａ）（Ｂ）の溝に比較して特に頑丈な構造とすることができる。The above is an advantage common to the grooves shown in (A), (B) and (C) of FIG. 1, but the groove shown in (C) has a large width at the root portion of the wall between windings. Therefore, the structure can be made particularly robust as compared with the other grooves (A) and (B).
