経年変化により機能が低下するなどの問題がある。In order to prevent disasters caused by abnormal temperature rises in discharge lamp ballasts or abnormal currents caused by interlayer short circuits, it is most common to incorporate thermal fuses, thermostats, etc. into the ballasts. However, when used for many years, there are problems such as a decline in functionality due to aging.

層間短絡が生じた場合の異常電流を減少させることかで
きる効果が得られる。As described above, in the present invention, the coil constituting one ballast is divided into a plurality of parts, each of the divided coils is wound around the main core at intervals, and leakage occurs between each of the divided coils. Since the iron core is embedded in the coil, the heat generated in the coil and main core is transmitted to the leakage core and radiated to the outside, so there is little temperature rise in the ballast.In addition, since the coil is divided into multiple parts, the heat generated in the coil and main core is radiated to the outside. The dielectric strength of the ballast may be low, which not only improves the safety of the ballast, but also reduces abnormal current when an interlayer short circuit occurs in the coil.
次にその場合の動作を説明する。Next, the operation in that case will be explained.
第6図aはコイルが分割されず又コイル間に漏洩鉄心の
ない従来の安定器を放電灯に接続した正常状態における
コイルと磁束分布を示す。FIG. 6a shows the coil and magnetic flux distribution in a normal state when a conventional ballast with no split coils and no leaky core between the coils is connected to a discharge lamp.
この状態で同図Cに示すようにコイルの一部nに層間短
絡が生じると、健全な部分のコイルmに対し層間短絡を
生じたコイルnがトランスの二次巻線と同様な関係にな
って、コイルnに同図bに示すように逆方向の異常電流
が発生し、そのためコイルnか加熱されて災害の原因と
なる。In this state, if an interlayer short circuit occurs in part n of the coil as shown in Figure C, the coil n that has experienced the interlayer short circuit will have a similar relationship to the secondary winding of the transformer with respect to the healthy part of the coil m. As a result, an abnormal current is generated in the opposite direction in the coil n as shown in FIG.
一方本発明では正常動作時には同図dに示すように主磁
束φのほかに漏洩磁束φ1,φ2,φ3,φ4かあるが
、各漏洩磁束は互いに逆方向であるので打ち消されて0
である。On the other hand, in the present invention, during normal operation, there are leakage magnetic fluxes φ1, φ2, φ3, and φ4 in addition to the main magnetic flux φ, as shown in figure d, but since each leakage magnetic flux is in the opposite direction, they are canceled out and 0.
It is.
この状態でコイル3dに層間短絡が生じると、同図eに
示すように健全なコイルによる主磁束φはその大部分が
漏洩鉄心4cを通り、層間短絡を生じたコイル3dに交
叉しなくなり、コイル3dに生じる逆起電力が低下し、
異常電流は減少し、その温度上昇が抑圧されて災害を未
然に防止することができる。If an interlayer short circuit occurs in the coil 3d in this state, most of the main magnetic flux φ from the healthy coil passes through the leaky core 4c and does not intersect with the coil 3d in which the interlayer short circuit has occurred, as shown in the figure e. The back electromotive force generated at 3d decreases,
Abnormal current is reduced and its temperature rise is suppressed, making it possible to prevent disasters.
なお、上述の実施例はいずれも外鉄型安定器の例である
が、本発明は外鉄型の場合のみでなく内鉄型の安定器に
も同様に実施することができる。In addition, although the above-mentioned embodiments are all examples of external iron type ballasts, the present invention can be implemented not only in the case of external iron type ballasts but also in internal iron type ballasts.
第7図はかかる場合の一例である。FIG. 7 shows an example of such a case.
同図において20は主鉄心、21a〜21hは分割され

挿入された漏洩鉄心を示す。In the figure, 20 is a main core, 21a to 21h are divided coils, and 22a to 22f are leaky cores inserted between each divided coil.
