Abstract
The article deals with technological possibilities of operation reliability enhancement of high-current electrical connections while assembling unattended assembly joints under the pressure of pulsed magnetic field. The results of numerical modeling and experimental research of the catenary assembly process for the monometallic, bimetallic and composite multistranded wires between themselves and between them and terminals including those resulting vias made of aluminum and copper. The results of heat and electric tests of resulted connections are presented. It is ascertained that mechanical breaking strength of connections obtained under the pressure of pulsed magnetic field reaches 98…100% of intact wire strength. The factors of electrical contact defectiveness per resistance and per overtemp with rated current while making magnetic-impulse assembly of a wire and a coupling are lower than limit values, which are established for connections of feed wires, connectors and connecting clamps, which are obtained by pressing.
