次に動作について三相電流を監視する場合を例にとっ
て説明する。Next, the operation will be described by taking the case of monitoring the three-phase current as an example.
まず、取付台（７）に取付ける場合は第６図の様に従

の高さにあるブスバー（11）の電流を監視することもで
きるがこの場合に電流検出器は、取付台（７）への取付
けのみで、ブスバー（11）の固定はしていない。First, when mounting on the mounting base (7), the conventional three-phase current sensor for chassis mounting (1) can be used as it is as shown in FIG. 6, and at this time, it is equivalent to the circular penetrating part (3). It is also possible to monitor the current of the bus bar (11) at the height, but in this case, the current detector is only mounted on the mounting base (7) and the bus bar (11) is not fixed.
次いで取付台（７）がなく直にブスバー（11）に取付

（８）にて宙釣り状態で固定する。また信号線（13）
は、電流検出器側が３方に分岐したものを用いている。Next, when the bus bar (11) is directly mounted without the mounting base (7), three single-phase current detectors (9) for mounting the bus bar are used as shown in FIG. In this case, it is fixed to the bus bar (11) having a screw hole by the mounting screw (8) via the bus bar mounting portion (12) in the state of air fishing. Signal line (13)
, The current detector side is branched into three directions.

った電流検出器とは絶縁距離を確保して取付ける。Finally, when mounting on the printed circuit board (14), only the one for single phase is installed as in the case of mounting on the bus bar (11). As shown in Fig. 10, the current detector (15) for mounting on the printed circuit board is installed. In this case, three conductive wires (4) are wound around the current detecting portion (2), and both ends of the conductive wire (4) and the leads of the output terminal (5) are fixed to the printed board (14) by soldering. At this time, a bare wire is often used as the conductive wire (4), so that the conductive wire (4) is mounted with an insulation distance from the adjacent current detector.
従来の電流検出器によって多相電流を監視する場合
は、以上のように構成されているので、その用途別にそ
れぞれ専用の電流検出器を用いなければならず、部品の
共用性に欠けていた。When the multi-phase current is monitored by the conventional current detector, since it is configured as described above, it is necessary to use a dedicated current detector for each application, which lacks the commonality of parts.
また、ブスバー（11）あるいはプリント基板（14）に
取付ける場合は、単相電流検出器を複数個用いなければ
ならず、取付スペースが増大し組立工数も増加する。Further, when mounting on the bus bar (11) or the printed circuit board (14), it is necessary to use a plurality of single-phase current detectors, which increases the mounting space and the number of assembling steps.
また、ブスバー（11）に取付ける場合、分岐した信号
線（13）を使っているので誤配線の恐れもある。In addition, since the branched signal line (13) is used when mounting on the bus bar (11), there is a risk of incorrect wiring.

器との絶縁距離を確保して取付ける必要があり、コスト
面、品質面においても問題点があった。When it is mounted on the printed circuit board (14), it is fixed only by the leads of the output terminal (5) and both ends of the conductive wire (4), so there is concern about strength. Also, a bare wire is used for the conductive wire (4). In the case of winding around the current detecting section (2), it is necessary to secure the insulation distance from the adjacent current detector, and there are problems in terms of cost and quality.
