| titleOfInvention | Rotary casting forming device and process for non-porous three-pillar insulator with gradient structure |
| abstract | The invention relates to the field of ultra-high voltage power transmission equipment manufacturing, and provides a rotary casting forming device and a process for a non-porous three-pillar insulator with a gradient structure. The device includes a two-component quantitative feeding system, a self-heating mold, a central rotating shaft, a negative pressure system and a The control system; the two-component quantitative feeding system outputs the epoxy resin mixture whose filler concentration changes with time to the self-heating mold; the self-heating mold can be closely attached to the central rotating shaft to heat, cure and shape the epoxy resin mixture; The negative pressure system makes the self-heating mold form negative pressure; the control system controls the feeding, forming negative pressure and the rotation of the central shaft. The invention can realize the gradient change of the dielectric constant of the three-pillar insulator along the radial direction of the pillar, and can freely set the control ability of the three-pillar insulator to the electric field, realize the integrated manufacturing of controllability and shape, avoid flashover along the surface, and avoid bubbles in the pouring process. The generated pores ensure the mechanical properties of the three-pillar insulator, and can be cast in batches to achieve large-scale benefits. |
