Current converter, preferably for circuit breaker, has U-shaped windings with parallel inner/outer arms, bridge covering one end, longer arm bent over other end, joined to next winding

摘要

The device has an annular core (11), a primary coil and a secondary coil (12). Each secondary winding has a rigid section about the core with ends connected to adjacent windings at the core outside. Each winding is U-shaped with different length arms parallel to surface lines inside and outside the core, the bridge covering one end surface of the core and the longer arm bent over the other end surface and joined to the next winding. The device has an annular core (11), a primary coil and a secondary coil (12) with at least one winding passing through the interior of the core. Each secondary winding has a rigid section about the core with ends connected to adjacent windings, preferably by laser or electron beam welding at the core outside. Each winding is U-shaped with different length arms parallel to surface lines inside and outside the core, the bridge covering one end surface of the core and the longer arm bent over the other end surface and joined to the next winding.
