Detachable connector of high current flat plate copper conductor

Abstract

The invention belongs to a detachable connector of a flat plate copper conductor longitudinal field coil in a fusion reaction experimental device. The detachable connector comprises copper plates at the two ends, the copper plates at the two ends are provided with slots which are all shaped like a finger, an insertion bar is inserted in each slot, a circular hole is formed in the middle of each insertion bar, and a locating pin is driven in the circular hole; two long holes are formed in each copper plate of the two ends, and four same holes are correspondingly formed in each insertion bar, wherein the holes near a seam are used for mounting draw-in bolt components, and the outer side holes are used for mounting expansion bolt components. The detachable connector of the high current flat plate copper conductor has the advantages that in the structure of the detachable connector of the high current flat plate copper conductor, the insertion bars play a role of conducting currents of the copper plates at the two ends, the material selection of the insertion bars is improved simultaneously, and the strength of the copper plate bodies is reduced due to the slots; the draw-in bolt components are pre-tightened to guarantee that the insertion bars are closely attached to the slot faces of the copper plates, and the good conductive performance is guaranteed; meanwhile, the mechanical strength of the whole connector is improved simultaneously.

Description

technical field [0001] The invention belongs to a detachable joint of a large-current flat copper conductor, in particular to a detachable joint of a longitudinal field coil of a flat copper conductor in a fusion reaction experimental device. Background technique [0002] The longitudinal field coil working in the nuclear fusion device has a current as large as 100-200kA and a magnetic field strength of 2-3T, which will generate a large in-plane electromagnetic force, and because of mutual induction with other coil currents and plasma currents An out-of-plane electromagnetic force is generated. Under such conditions, the coil has to be made into a detachable structure. Ordinary electrical connectors cannot meet the needs. Coupled with the space limitation of the connector position, it cannot be clamped in a direction perpendicular to the large area of ​​the coil conductor. , so it is urgent to develop a joint that can satisfy both low resistance and high mechanical strength ...
