阅读说明：本技术 单体的玻璃环和用于光学电流测量的方法 (Monolithic glass ring and method for optical current measurement ) 是由 S.舒伯思 于 2019-09-06 设计创作，主要内容包括：本发明涉及一种用于电流测量的玻璃环(1),其具有玻璃体,玻璃体可以围绕电导体(2)布置并且具有光进入面(4)和光逸出面(5)。玻璃环(1)构造用于,可以使通过光进入面(4)进入玻璃体内的光在玻璃体中通过在玻璃体的外表面上的反射、完全环绕导体(2),其中,光在光逸出面(5)上从玻璃体逸出。玻璃环(1)由单体的玻璃体构成。根据本发明的用于光学电流测量的方法包括,在电导体(2)中的电流(3)产生围绕导体(2)的电磁场,通过电磁场、在光束围绕导体(2)环绕时改变围绕导体(2)布置的玻璃环(1)中的光束的偏振,其中玻璃环尤其以一个平面垂直于导体的纵轴线。(The invention relates to a glass ring (1) for current measurement, comprising a glass body which can be arranged around an electrical conductor (2) and has a light entry surface (4) and a light exit surface (5). The glass ring (1) is designed such that light entering the glass body through the light entry surface (4) can completely surround the conductor (2) in the glass body by reflection on the outer surface of the glass body, wherein the light escapes from the glass body at the light exit surface (5). The glass ring (1) is formed from a single glass body. The method according to the invention for optical current measurement comprises generating an electromagnetic field around a conductor (2) by means of a current (3) in an electrical conductor (2), changing the polarization of a light beam in a glass ring (1) arranged around the conductor (2) when the light beam is looped around the conductor (2) by means of the electromagnetic field, wherein the glass ring is perpendicular to the longitudinal axis of the conductor, in particular in one plane.)
