Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic pulse crimping, in particular to an electromagnetic pulse crimping device for a tubular insulated bus conductor. Background Art

[0002] Due to its high current carrying capacity, good insulation and heat dissipation performance, tubular insulated busbars are often used in power transmission systems, especially high-voltage distribution networks. When connecting tubular insulated busbars, copper connecting tubes are usually required, which are mainly formed by crimping the tubular insulated busbar conductor and the copper connecting tube.

[0003] At present, crimping is mainly carried out through mechanical crimping methods such as hydraulic pliers. However, this mechanical crimping method has defects such as uneven crimping force, large gaps in the cross-section of the crimped copper connecting tube, poor crimping effect and poor connection reliability. Based on this, an electromagnetic pulse crimping forming technology has been developed. It is a method that uses the instantaneous high pressure and high speed generated by electromagnetic pulses to achieve metal material connection. Electromagnetic pulse crimping can complete the connection in a very short time, greatly improving production efficiency; at the same time, electromagnetic pulses can produce uniform pressure distribution to ensure close bonding of the connection area.

[0004] However, the electromagnetic pulse crimping equipment currently used for tubular insulated busbar conductors can only complete the alignment and compression of one set of tubular insulated busbars and copper connecting tubes at a time. After each set of tubular insulated busbars and copper connecting tubes is crimped, they need to be continuously disassembled, assembled and replaced. The disassembly, assembly and replacement time accounts for a large proportion, and the overall work cycle is long.
