CLIP-ON CURRENT TRANSDUCER OR CURRENT TRANSFORMER

摘要

Electrical current transducer for mounting around an electrical primary conductor carrying a current to be measured, comprising a primary conductor receiving aperture (16), a housing (4), a magnetic core (6) mounted in the housing, and a secondary coil (10) wound around a branch of the magnetic core. The housing comprises a major portion (4a) and a minor portion (4b), the major portion being separable from the minor portion and configured to be mounted and locked around the primary conductor, the housing major and minor portions joinable together at joining faces (32a, 36a). The magnetic core comprises a major portion (6a) mountable in a core receiving cavity (20) of the housing major portion (4a), and a minor portion (6b) mountable in a core receiving cavity (22) of the housing minor portion (4b). The housing further comprises an electrical component support body (4c) comprising a coil support portion (28) around which the secondary coil is mounted, the secondary coil and coil support portion being received in a first branch receiving portion (20a) of the core receiving cavity of the housing major portion (4a), the coil support portion comprising a core receiving cavity (26) comprising a first branch receiving portion (26a) receiving a first branch (7a) of the magnetic core major portion (6a) therein, a longitudinal axis (A) of the magnetic core first branch (7a) being in a transverse direction to the general direction of the joining faces (32a, 36a).
