Apparatus for electrically connecting at least four electrical conductors
An apparatus for electrically connecting at least four electrical conductors includes a connecting element and at least four shielding pipes, which are each provided for receiving at least one conductor. In order to enable a simple and economical connection, the connecting element forms pipe connection pieces and each connection piece is integrally joined or materially bonded to a respective shielding pipe.
1. An apparatus for electrically connecting at least four electrical conductors, the apparatus comprising:
at least four shielding pipes each configured to receive at least one of the conductors;
a connecting element forming pipe connection pieces, each of said pipe connection pieces being connected to a respective one of said shielding pipes by a material-bonded connection; and
a paper insulation surrounding said connecting element, said pipe connection pieces and said shielding pipes.
2. The apparatus according to claim 1 , wherein said connecting element and each of said shielding pipes are formed of an electrically conductive material.
3. The apparatus according to claim 1 , wherein each of said pipe connection pieces is soldered or welded to a respective one of said shielding pipes.
4. The apparatus according to claim 1 , wherein said pipe connection pieces have at least one of different structures or different diameters.
5. The apparatus according to claim 1 , wherein said pipe connection pieces and said shielding pipes respectfully connected to said pipe connection pieces have different diameters from one another.
6. A transformer, comprising an apparatus according to claim 1 .
7. An inductor, comprising an apparatus according to claim 1 .
8. An apparatus for electrically connecting at least four electrical conductors, the apparatus comprising:
at least four shielding pipes each configured to receive at least one of the conductors;
a connecting element forming pipe connection pieces, each of said pipe connection pieces being connected to a respective one of said shielding pipes by a material-bonded connection; and
a barrier system made of pressboard, said shielding pipes and said connecting element being surrounded by said barrier system.
9. The apparatus according to claim 8 , which further comprises a housing of a transformer or an inductor, said connecting element and said shielding pipes being disposed in an oil bath inside said housing.
10. The apparatus according to claim 9 , wherein said transformer or said inductor has windings, and at least one of the conductors is electrically conductively connected a respective one of said windings.
11. An apparatus for electrically connecting at least four electrical conductors, the apparatus comprising:
at least four shielding pipes each configured to receive at least one of the conductors;
a connecting element forming pipe connection pieces, each of said pipe connection pieces being connected to a respective one of said shielding pipes by a material-bonded connection; and
at least one of said pipe connection pieces and said shielding pipe connected thereto forming a contact point and spanning an angle (alpha) of less than 180 degrees with one another with respect to said contact point.
