Abstract
The utility model relates to a composite support insulator used for a high pressure power transmitting in the electric industry, consisting of a flange, a mandrel and an umbrella cover, which is characterized in that the mandrel is sleeved with a plurality of umbrella covers outside, and the mandrel consists of an insulation sleeve and a filling object; wherein, the insulation sleeve is a hollow tube made by winding epoxy glass fabrics. As the insulation sleeve is a hollow tube made by winding epoxy glass fabrics, the utility model improves the comprehensive mechanism intensity of the insulation sleeve; furthermore, due to the filling object in the insulation sleeve and the proportion of the lower filling bigger than the proportion of the upper filling, the utility model makes the mandrel in a light weight, providing perfect economics.
Description
The utility model relates to a kind of composite post insulator that the power industry high voltage power transmission is used.
Relevant by retrieval patent documentation does not retrieve the composite post insulator identical with the utility model structure at present as yet.The high-voltage strut insulator of common outdoor use is generally porcelain rod insulator.Along with improving constantly of scientific and technological level, people have higher requirement to the power station electric equipment.Not only require to have higher insulation property for the power station with composite post insulator, also want to bear bending, reverse, composite machine load such as stretching, how to develop the high-performance composite post insulator, the running quality of raising equipment, be the new problem of pendulum in face of people, so person skilled is being occupied in research with great concentration.
The purpose of this utility model is to provide that a kind of to adopt the mixture of composite material be packing material, has the intensity height, a kind of composite post insulator that insulation is good.
Technical characterictic of the present utility model is: be designed on the basis of considering dependable performance, a kind of composite post insulator that it is made up of flange, plug, umbrella cover, umbrella cover is formed by silicon rubber vulcanization, outer cover at plug is equipped with several umbrella covers, two ends at plug are fixed with flange, described plug is made up of insulating case, filler, and insulating case is that epoxy glass fiber twines the hollow pipe of making.
Filler in the described plug by following filler, go up filler and form, described filler down is the mixture of quartz sand and epoxy resin, described on filler be the mixture of swelling perlite powder and epoxy resin.
Described umbrella cover is made up of last coupling part, full skirt part, following coupling part, and the full skirt partial design becomes downward-sloping version, and the lower edge of full skirt part is provided with the circular arc A that falls into water; On the external diameter of following coupling part, be provided with circular arc B.
During assembling, be packed on the flange, on the outer wall of plug, coat binding agent with the end of binding agent with plug, be fixed in several umbrella covers on the plug respectively, and coat binding agent in the coupling part of adjacent umbrella cover, the other end with plug installs upper flange again, then obtains the utility model.
The utility model has the advantages that; Because insulating case adopts epoxy glass fiber to twine and makes, thereby improved the intensity of insulating case because insulating case inside is provided with filler, and down the proportion of filler greater than the proportion of last filler, thereby make in light weight, the good economy performance of plug.Because the junction of adjacent two umbrella covers is designed betwixt apart from the middle part, thereby make umbrella cover be not easy to damage; Because the lower edge of umbrella cover full skirt part is provided with the circular arc A that drips, the external diameter of following coupling part is provided with circular arc B, thereby has reduced the generation of point discharge phenomenon; Because the mode that adopts several umbrella covers to link to each other forms overall structure, thereby make product be easy to processing; Because simple in structure, dependable performance is so there is very big practical and popularizing value.
Below with reference to description of drawings embodiment of the present utility model:
Accompanying drawing 1 is the structural representation of the utility model composite post insulator.
Accompanying drawing 2 is structural representations of the umbrella cover of composite post insulator.
With reference to accompanying drawing 1, accompanying drawing 2, the utility model is made up of flange 1, plug 2, umbrella cover 3, coats binding agent in the outside of plug 2, is set with several umbrella covers 3; Described plug 2 is made up of insulating case 4, filler 5, and insulating case 4 twines the hollow pipe of making for epoxy glass fiber.Filler 5 in the plug 2 is by descending filler 6, last filler 7 to form, and following filler 6 is the mixture of quartz sand and epoxy resin, and last filler 7 is the mixture of swelling perlite powder and epoxy resin.Described umbrella cover 3 adopts silicon rubber vulcanization to form, umbrella cover 3 is made up of last coupling part 8, full skirt part 9, following coupling part 10, full skirt part 9 is designed to downward-sloping version, and the lower edge of full skirt part 9 is provided with the circular arc A that drips, and is provided with circular arc B on the external diameter of following coupling part 10.Two ends at plug 2 are fixed with flange 1 respectively with binding agent.
