Abstract

The invention relates to a preparation process of an inner umbrella skirt of a hollow post composite insulator, which comprises the following steps: A, preparing raw materials: manufacturing a steel core, and manufacturing a circular epoxy resin plate and a circular epoxy resin pipe which are coated with PRTV (permanent-room-temperature-vulcanized) paint; B, assembling: installing an end fixing device at one end of the steel core, sequentially embedding and sleeving the circular epoxy resin plate and circular epoxy resin pipe in the steel core, compressing, and installing another end fixing device at the other end of the steel core; C, additionally spreading nano reinforced fluorinated silicone rubber paint at the seams on the surfaces of the assembled circular epoxy resin plate and circular epoxy resin pipe; D, uniformly spraying a coupling agent onto the surfaces of the circular epoxy resin plate and circular epoxy resin pipe; E, wrapping with glass fibers, and shaping; and F, removing the auxiliary devices, thus finishing the manufacturing process of the inner umbrella skirt. The hollow post composite insulator prepared by the invention has the characteristics of favorable bending strength, long inner insulation leakage distance, blanketing gas erosion resistance and the like.

Description

Technical field [0001] The present invention involves the field of pillars composite insulator technology, especially the preparation process involving an empty core pillar composite insulator inner umbrella skirt. Background technique [0002] In various electrical equipment, insulators are often used.At present, the pillar insulator used in a large number of domestic high -voltage projects includes three types: porch pillar insulator, porcelain core pillar composite insulator, and pillar composite insulator.The existing pillar composite insulator is basically a real core structure, and rarely is the empty core structure.Internal filling SF6, N2 or other insulating gas of the core structure.The empty core composite insulators made of epoxy glass fiber wound tube as the substrate have the characteristics of explosion -proof and strong resistance, good shock resistance, small size, light weight, good anti -aging, no need to clean, no maintenance and other characteristics.Although ...
