INDUCTION APPARATUS FOR CABLE CONNECTION AND REPAIRS Russian patent published in 2005 - IPC

FIELD: electrical engineering; design features of induction apparatuses for cable connection and repairs.

SUBSTANCE: proposed induction apparatus has laminated core with odd number of legs, each carrying inductor coils, as well as two ferromagnetic steel half-molds with inserts mounted on magnetic core loose ends; plane of half-mold split joint is aligned with direction of magnetic flux in mentioned legs. Electromagnetic shunts assembled of set of electric steel plates are installed on external surfaces of half-molds; only first copper or brass insert is electrically connected in half-molds to their edges, this electrical connection being made both in left- and right-hand parts of half-molds and its total length amounting to width of extreme leg and half the distance between extreme and central legs. Next inserts of half-molds are made of metal immune to frictional sparking.

EFFECT: enlarged functional capabilities, reduced consumption of high-cost copper due to highly uniform temperature field built up by apparatus.
