Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gas insulated transmission line (GIL) processing tooling, in particular to a three-phase common box GIL intelligent conductor automatic clamping device for preventing axial movement. BACKGROUND

[0002] The three-phase common box GIL is a core device for high-voltage power transmission with large capacity and long distance. The three-phase metal conductor inside the device needs to be crimped and formed with the end of the three-pole insulator. The stress, coaxiality and surface integrity of the crimping interface between the conductor and the insulator directly determine the long-term insulation performance, electrical performance and operation reliability of the GIL. The existing GIL conductor assembly tooling has three major defects: (1) Conductor transfer relies entirely on manual lifting: GIL conductors are heavy metal pipes, and manual lifting and transfer are prone to knocking the conductor outer wall, causing conductor eccentricity and deviation. Manual positioning on the roller table has poor positioning accuracy, and the labor intensity is high. High-altitude lifting poses a risk of workpiece falling and personnel knocking; (2) No reliable axial positioning structure for crimping process: The tooling roller table only provides radial support for the conductor, without an axial constraint structure. When the external crimping device exerts pressure, the conductor slips axially under the pressure, forming irreversible residual internal stress at the crimping interface. After long-term operation of the device, interface cracking, contact resistance soaring, and metal particle shedding may occur, significantly reducing the service life of the GIL; (3) Transfer clamps and crimping positioning tooling are separate: In traditional production lines, the conductor transfer tooling and the crimping positioning tooling are independent of each other. After the conductor transfer is complete, it needs to be positioned again by manual clamping. The process is complicated, the assembly efficiency is low, and it is difficult to unify the coaxiality of the three-phase conductors. Batch products have poor quality consistency.

[0003] The existing GIL conductor clamping tooling can only achieve single conductor transfer or static positioning, and cannot integrate automatic feeding and crimping axial two-way locking functions, making it difficult to meet the high-precision, automated batch assembly production needs of three-phase common box GIL.
