Description of the Invention: [Technical Field] The present invention relates to an optical converter for an electronic device, and is particularly useful for an optical converter for an electronic device which can improve the measurement accuracy of current. [Prior Art] Normally, (4) Electronic devices such as the home appliance, gas circuit breaker, and Qianguanyuan main bus are used as power transmission and distribution equipment. In these electronic machines, in order to measure the current flowing through the through-body disposed in the sealed container, a scheme using an optical converter has been proposed. - Lulu's Newstream H uses a conventional glass fiber as a current sensor. In the case of the reflective optical converter, as shown in FIGS. 9(a) and 9(b), when the current-carrying conductor 1 through which the current flows is disposed in a container (not shown) in which a circular electronic device is formed The optical fiber 2 is wound around the current-carrying conductor 1 so that the current-carrying conductor 1 and the optical fiber 2 are perpendicular (intersecting). An optical element 3 having a permanent magnet is disposed at one end of the optical fiber 2, and the reflective element 4' is disposed at the other end. The optical element 3 and the reflective element 4 are disposed on a winding circle of the optical fiber 2, that is, The winding of the optical fiber 2 wound around the axis of the current-carrying conductor 1 is perpendicular (intersecting). As a result, for example, as shown in FIGS. 9(a) and 9(b), when the current I flows upward from the lower side of the current-carrying conductor 1, a magnetic field Η generated in a direction perpendicular to the current I is added to the optical fiber 2. In this reflective optical converter, linear light is formed from a light-emitting portion (not shown)

Since the incoming linearly polarized light system is an outgoing light beam that is rotated by the Faraday effect of the optical fiber, the rotation of the incident light beam is calculated by the measuring unit, and the energization current is measured. In the Japanese Patent Laid-Open Publication No. 2000-314751 (Patent Literature!), it has been proposed to combine the optically variable flow H with an electronic device, and the optical fiber for arranging the wound electric conductor is used for the end face in the axial direction. The scheme of the ring frame. In the optical greening system described in Patent Document 1, the light is fixed in the groove of the annular frame and the conductive mosquito is placed at the end of the circumference (10) (four), and the polarizing portion extending in the surrounding direction is disposed. With the test piece. Due to the structure in which the splint is formed, the total length is shortened as compared with the phase of the it-like frame, and the optical transmission loss can be reduced. Further, in the Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The influence of the magnetic field generated by the current flowing through the energized conductor is also eliminated, and no measurement error is generated. In the _streamer described in Patent Document 2, when the winding end portion of the optical fiber is folded outward, the input end of the polarizer is disposed, and the output end of the analyzer is disposed, from the position where the optical fiber is wound to the input end. By the magnetic cover, it is possible to prevent the influence of the magnetic field and form a high precision without measurement error. In the conventional light-converting flow shown in FIG. 9 described above and the light 201209421 converter described in the patent document, the optical element (4) is disposed on a winding circle of an optical fiber that is perpendicular (crossed) to the direction in which the current conductor is scented, that is, The winding extension line of the optical fiber perpendicular to the axial direction of the energization conductor , is disposed with the optical q · , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , direction. In such a light-changing flow H, a magnetic field due to a current flowing through the current-carrying conductor increases the influence on the permanent magnet in the optical element, which is a cause of measurement error. That is, the reason is as follows. The optical element _ permanent magnet has the effect of its magnetic field so that the linearly polarized wave is audible and (four) is light money. When a current flows through the current-carrying conductor, a magnetic field is generated. However, when the magnetic field of the wire element_permanent magnet coincides with the direction of the magnetic field generated by the current flowing through the current-carrying conductor, even if the magnetic field is further added from the outside, the linearly polarized light is saturated by 6 Not affected. However, when the direction of the magnetic field of the permanent magnet is opposite to the direction of the magnetic field η generated by the current 丨 flowing through the current-carrying conductor ', if it is formed (the magnetic field generated by the permanent magnet) _ (the magnetic field generated by the current flowing through the energizing conductor) < (Linear-polarized wave-light saturation magnetic field), the linearly-polarized wave becomes incapable of being saturated, and the current value is measured on the premise that the magnetic field of the permanent magnet in the optical element 3 is saturated, which is a cause of the error. Further, as in the case of the current-carrying device of Patent Document 2, when the winding end portion of the optical fiber is disposed as the input end of the polarizer and the output end of the polarizer is disposed, the magnetic cover is covered to eliminate the influence of the magnetic field. The winding end of the optical fiber is complicated in construction and makes it difficult to manufacture.

In the electronic (four) optical converter according to the present invention, when the optical fiber is wound around the current conducting conductor, the permanent magnet in the optical element disposed at the end of the optical fiber is disposed on the shaft passing through the conducting conductor. In the virtual plane created, the magnetic field of the permanent magnet is significantly less affected by the magnetic field generated by the current flowing through the current conducting conductor. The optical unit n of the present invention can be used to improve the measurement accuracy of current more than a conventional optical converter by a simple configuration. [Embodiment] The optical converter for an electronic device according to the present invention is characterized in that an optical converter for an electronic device is provided with a current-carrying conductor in a container of an electronic device, and the optical fiber is wound around the axial direction of the current-carrying conductor. An optical element having a permanent magnet is disposed at one end of the optical fiber while a reflective element is disposed at the other end.

[Embodiment 1] Hereinafter, the optical converter for an electronic device according to the present invention will be described in the same manner as in the prior art, with the same reference numerals as in the drawings. As shown in Fig. 4 (4) and Fig. 1, the current-carrying conductor 1 through which the current flows is disposed inside the electronic device (not shown) which forms a closed electron, and is sealed by using an insulating gas. In this case, the optical fiber 2 is wound around at least one turn in a manner to surround it.
