Embodiment Construction
[0010] figure 1 The structure of the hollow silicone rubber composite insulator of the present invention is shown. The insulator 1 is a glass fiber reinforced epoxy cylinder. Flanges 2 are fixed at both ends of the insulator 1. The outside of the insulator 1 is a silicone rubber shed made of silicone rubber shed segments 3. .
[0011] Such as image 3 As shown, the production steps are as follows:
[0012] A. Two or more sets of prefabricated silicone rubber shed segments 3 are first connected in series and then bonded with conventional silicone rubber adhesives to form a silicone rubber shed, that is, an outer insulator. The entire outer insulator is fixed in the special fixture 4, and the two ends are sleeved with the flange 2, so that the outer insulation and the flange 2 form a sealed outer mold 5.
[0013] B. Making the fiber fabric layer 14 of the insulator 1: the fiber roving is used to weave a cylindrical profiling fabric in advance, the axial direction of the tubul...

Abstract
The invention discloses a production method for a hollow silicon rubber composite insulator. The method is characterized by comprising the following steps of: prefabricating a silicon rubber integral umbrella skirt or umbrella skirt segments, fixing the prefabricated silicon rubber integral umbrella skirt or the sequentially connected umbrella skirt segments on a special clamp, and arranging flanges on two ends, taking the flanges as external molds; and shaping an epoxy resin glass steel inner insulator on an inner side of the external mold silicon rubber umbrella skirt by a vacuum diversion shaping technology, curing the insulator and removing the clamp, and arranging and processing to obtain the hollow silicon rubber composite insulator. The reinforcing fiber of the inner insulation glass steel in the technology is made into fabrics according to direction strength of each product, and the flexural modulus is more than 25 GPa so that the performance of fiber materials of insulation pipes is best developed; the material resource is saved; shaping of the inner insulation pipe is the last procedure so that the reliability and the stability are higher; and a vertical matched mold repairing seam does not exist in the technology so that the insulation strength is not reduced caused by dust at the matched mold seam, and the insulation property of the product is higher.
Description
technical field [0001] The invention relates to a hollow insulator for high-voltage electrical appliances in the electric power industry, specifically a production method in which a silicone rubber integral shed or a plurality of silicon rubber single sheds are sleeved and bonded as the outer insulation, and epoxy glass fiber reinforced glass steel is used as the inner insulation. Background technique [0002] The existing hollow insulators for electric high-voltage electrical appliances mainly include porcelain insulators and silicon rubber composite insulators. A technology similar to the present invention is the silicone rubber composite insulator. Silicone rubber composite insulators currently on the market have strong pollution flashover resistance and light weight, but their disadvantages are that the outer insulating shed is molded in two halves, and there are mold closing and trimming seams that run through from top to bottom, which affects certain insulation stabili...
