线圈式传感器、包括其的测量装置、断路器及其缠绕方法
摘要：
一种用于测量电流的罗氏线圈式传感器，包括：载体和至少一个次级绕组(3)。该绕组包括：具有高匝密度的至少一个内层(6)，沿从绕组(3)的第一端(5)朝向相对的第二端(9)的“向外”的第一缠绕方向(10)缠绕，以及具有低匝密度的至少一个外层(7)，所述层沿“返回”的第二缠绕方向(11)缠绕。具有低匝密度的外层包括：具有高匝密度的第一补偿部分(12)，该部分具有小的长度(L1)并且接近第一端，具有低匝密度的中部部分(13)，该部分具有大的长度(L2)，以及具有高匝密度的第二补偿部分(14)，该部分具有小的长度(L3)并且接近第二端。
摘要（英）：

A Rogowski coil type sensor for measuring current includes a carrier and at least one secondary winding (3). The winding includes: at least one internal layer (6) with a high turn density, which layeris wound in an 'outward' first winding direction (10) from the first end (5) to a second opposite end (9) of the winding (3), and at least one external layer (7) with a low turn density, which layeris wound in a 'return' second winding direction (11). The external layer with a low turn density includes: a first compensating portion (12) with a high turn density, which portion is of small length(L1) and close to the first end, a central portion (13) with a low turn density, which portion is of large length (L2), and a second compensating portion (14) with a high turn density, which portion is of small length (L3) and close to the second end.
