Abstract

The invention provides a positioning method for a conductive end of a solid-insulation-embedded pole in an insulating sheath casting process. An upper conductive terminal of the solid-insulation-embedded pole is fixed to the static conductive end of a vacuum interrupter. The positioning method is characterized in that the dynamic conductive end of the vacuum interrupter is fixed into a cylindrical chamber; the cylindrical chamber positions the outer cylindrical surface of the vacuum interrupter; a cylindrical end surface at one side of an additional fixing components abuts against the contact surface of the upper conductive terminal and furthermore the additional fixing component and the upper conductive terminal are coaxially arranged; the fixing component penetrates through the through hole of the additional fixing component and is fixed to the mounting hole of the upper conductive terminal; and the other side of the additional fixing component is positioned on the upper end surface of a vertical pole. Furthermore the invention provides a positioning device for the conductive end of the solid-insulation-embedded pole in the insulating sheath casting process. The invention provides the positioning method and the positioning device for the conductive end of the solid-insulation-embedded pole in the insulating sheath casting process, wherein the positioning method and the positioning device effectively prevent contact resistance increase and equipment temperature increase.

Description

Technical field [0001] The invention relates to the processing technical field of a solid-sealed pole, in particular to a method and device for positioning the conductive end of a solid-sealed pole used in an insulating sheath casting process. Background technique [0002] The insulating sheath of the solid-sealed pole is manufactured by casting or injection, and the vacuum interrupter connected with the conductive end is required to be coaxial with the insulating sheath. To facilitate the placement of conductive terminals as inserts in the mold, additional fixing elements for transition are provided in the mold. The additional components can be positioned in the mold. Therefore, the connection position with the conductive end also needs to be relatively fixed, and the insulating material can be removed after cooling and solidification. [0003] In order to solve the problem of figure 1 For the rotation and positioning of the middle X-axis, it is currently commonly used to open tw...
