Abstract

The invention discloses a manufacturing device and method for a dual-component mixed epoxy casting dielectric functional gradient insulator. The manufacturing device comprises a dual-material feedingsystem, wherein an extrusion head of the feeding system is arranged on a three-dimensional motion system; the diameter of a spray hole of the extrusion head is adjustable, and one end of the extrusionhead is positioned inside an epoxy casting metal mould; the three-dimensional motion system is connected to a control system; the control system and the feeding system are separately connected to a computer through cables for raw material supply, mixing and extruding as well as control, on X-direction, Y-direction and Z-direction positions, of the extrusion head, so that manufacturing of a dielectric-constant functional gradient insulator is accomplished. Two epoxy resin composite materials of different dielectric properties are mixed on line, so that materials are accurately transferred to specific positions in the mould through a three-dimensional motion platform, and a large-dimension insulator with continuous dielectric characteristic gradient distribution can be manufactured withoutchanging other characteristics of an insulating structure, and therefore, along-surface electrical resistance is improved.

Description

Technical field

[0001] The invention belongs to the technical field of high-voltage equipment manufacturing, and specifically relates to a two-component mixed epoxy pouring dielectric functionally graded insulation manufacturing device and method. Background technique

[0002] Epoxy cast insulators have been widely used in power equipment such as switch cabinets, metal-enclosed SF6 insulated composite electrical appliances and power transmission lines (GIS and GIL) due to their excellent comprehensive performance. Since the electrical strength along the surface of the insulator is relatively low compared to the body characteristics, it directly determines the overall performance of the power equipment. In addition, with the development of equipment miniaturization, how to reduce the scale of the insulation structure is also a key issue to be solved urgently. Because the traditional epoxy cast insulation structure is a homogeneous material, the electric field distribution is unev...
