測定値の再現性が悪いという欠点がある。(3) Prior Art and Problems As detectors using conventional coils, those using Rogowski coils and search coils are known. These coils have the following drawbacks: That is, in the former case, if it is desired to obtain an accurate discharge waveform, the number of turns of the coil must be increased. In such a case, since the output becomes large, there is a drawback that a monitoring device capable of responding to the output must be prepared. In addition, in the latter case, it is sensitive to positional changes,
The disadvantage is that the reproducibility of measured values is poor.

This is achieved by forming the above-mentioned coil and making the number of turns of the outward coil winding portion different from the number of turns of the return coil winding portion.
(6) 考案の実施例
以下、添付図面を参照して本考案の実施例を説
明する。(6) Embodiments of the invention Hereinafter, embodiments of the invention will be described with reference to the attached drawings.
添付図面は本考案の一実施例を示す。１は絶縁
性ボビンで、その上に電流検出素子であるコイル
２が巻装され、その巻装端は積分回路３を介して
モニター装置４へ接続されている。コイル２は往
路コイル巻装部分２ａとこの部分２ａの巻装方向
とは逆向きの復路コイル巻装部分２ｂとから成
り、これらコイル巻装部分の巻数は異ならしめて
巻装されている。 The accompanying drawings illustrate an embodiment of the invention. Reference numeral 1 denotes an insulating bobbin, on which a coil 2 serving as a current detection element is wound, and the winding end thereof is connected to a monitor device 4 via an integrating circuit 3. The coil 2 consists of an outward coil winding section 2a and a return coil winding section 2b which is opposite to the winding direction of this section 2a, and these coil winding sections are wound with different numbers of turns.
この構造によれば、往路コイル巻装部分２ａは
ボビン１上で右巻きに巻かれ、ボビン１を一周し
たところで左巻きに巻き戻されて復路コイル巻装
部分２ｂを形成し、それらコイル巻装部分の巻数
に差があるから、各コイル巻装部分での巻数が多
くても、電流の検出に実効的に効いて来る巻数は
上述の巻数差となる。従つて、高電流パルスを低
い電流検出素子出力で正確に、しかも再現性よく
簡単に測定することが出来る。 According to this structure, the outward coil winding portion 2a is wound clockwise on the bobbin 1, and after going around the bobbin 1, it is unwound counterclockwise to form the return coil winding portion 2b. Since there is a difference in the number of turns, even if the number of turns in each coil winding part is large, the number of turns that is effectively effective for current detection is the difference in the number of turns described above. Therefore, high current pulses can be easily measured accurately and with good reproducibility with a low current detection element output.
上記実施例で述べた巻数差が実効的に得られる
ならば、各コイル巻装部分の構造に制限はない。 As long as the difference in the number of turns described in the above embodiment can be effectively obtained, there is no restriction on the structure of each coil winding portion.
