COIL OF DIFFERENTIATION INDUCTION CURRENT CONVERTER Russian patent published in 2018 - IPC H01F38/32 H02H7/45 

FIELD: electricity.

SUBSTANCE: coil covers an entrance insulator in any electric equipment: a switch, a power transformer or another. The input bus is the conductor through which the measured current passes. The coil of differentiation induction current converters (DICC) contains a carrying toroid, made on the basis of an elastic tube of dielectric material, the interface surfaces of which are tightly connected one with another when installing the DICC coil on the coupling sleeve of the entrance insulator. N identical sectional circular solenoids have single-layer windings. The winding connectors with detachable contacts and (n-1) couplings are made of rigid insulating material and attached to the carrying toroid. Each of the couplings is equipped with two tongues having the form of a circular cylinder. The first tongue of m-th coupling is tightly connected with the cylindrical bore of the m-th solenoid frame, and the second tongue of the m-th-coupling - with the cylindrical bore of the (m +1)-solenoid frame. Sectional couplings are evenly distributed along the axial line of the carrying solenoid. The return wire extends inside the coil in the cylindrical through channels of the couplings in the direction opposite to the longitudinal centreline of the coil. The start of the return wire is connected to the end of the coil of the n-th solenoid. The start of the coil of the first solenoid and the end of the return wire are connected to the coil clamps.

EFFECT: reducing the cost of differentiation inductance current converters by simplifying the manufacturing and installation techniques.
