Abstract
The utility model relates to a post composite insulator for a 126 kV outdoor high-voltage AC isolation switch used in the power industry. The post composite insulator comprises an upper connecting part, a core bar, an umbrella body, a sheath and a lower connecting part, wherein the upper connecting part is fixedly adhered at the upper end of the core bar; the umbrella body with an integral structure is fixedly adhered at the external part of the core bar; the core bar is a bar body formed by drawing and squeezing epoxy glass fiber reinforced resin; the umbrella body is integrally made of high-temperature vulcanized silicone rubber by vacuum injection molding; the lower end of the core bar is fixedly adhered onto the lower connecting part; and the lower connecting part is adhered to the sheath connected with the umbrella. Since the lower connecting part is a heightened fixed base body, the stability and the verticality of the core bar and the umbrella body are enhanced, thereby ensuring the reliability of switch on and switch off operation of the isolation switch; since the sheath is arranged, the post composite insulator can meet the requirement of insulation distance. Because of the sheath, the post composite insulator can meet the requirement of insulation distance. The post composite insulator also has the advantages of lowered weight, and improved toughness and shock resistance due to the adoption of the core bar and the umbrella body, which are prepared by the above method.
Description
Technical field
The utility model relates to a kind of post composite insulator that power industry is used, specifically a kind of 126kV outdoor high-voltage alternating current isolating switch post composite insulator.
Background technology
Relevant by retrieval patent documentation does not retrieve the 126kV outdoor high-voltage alternating current isolating switch post composite insulator identical with the utility model structure at present as yet.Existing isolated switchgear mainly is divided into two big classes with insulator: the porcelain insulator of ceramic material and porcelain core composite insulator.Porcelain insulator is because weight is big, anti-pollution characteristic is low, poor seismic behavior, burning process complexity, large-scale porcelain vase rate of finished products is low, application brings certain difficulty to product, and because weight is big, particularly at wind and snow weather, phenomenons such as inclination then appear easily, bring potential safety hazard for the normal operation of power transmission and transformation,, produce actual needs to satisfy better so be necessary existing outdoor high-voltage alternating current isolating switch is improved with insulator.
Summary of the invention
The purpose of this utility model is that a kind of employing glass fiber reinforced epoxy resin will be provided is that material is made plug, the integrally-built high-temperature silicon disulfide rubber umbrella of peripheral hardware body has a kind of 126kV outdoor high-voltage alternating current isolating switch post composite insulator that stability is good, perpendicularity is high.
To achieve these goals, the utility model adopts following technical scheme:
126kV outdoor high-voltage alternating current isolating switch post composite insulator, comprise end connection, plug, umbrella body, sheath, following end connection, last end connection cements in the upper end of plug, outside cementation at plug has an integrally-built umbrella body, plug is the barred body that epoxy glass fiber strengthens the resin pultrusion, the umbrella body is for being the integral body of material vacuum injection molding with the high-temperature silicon disulfide rubber, also cementation has a following end connection in the lower end of plug, and cementation has the sheath that links to each other with the umbrella body on end connection down.
Described plug is to be impregnated with the solid that the glass fibre pultrusion of epoxide-resin glue forms, and the glass fiber yarn in the plug is uninterrupted glass fiber yarn.
The high-temperature silicon disulfide rubber of described preparation umbrella body is made up of methyl vinyl silicone rubber and white carbon, aluminium hydroxide, silicone oil, vulcanizing agent, and its composition by weight is: methyl vinyl silicone rubber 20～50%, white carbon 20～57%, aluminium hydroxide 20～50%, silicone oil 2～5%, vulcanizing agent 1%.
Described sheath is the integral body with the high-temperature silicon disulfide rubber vacuum injection molding, form by methyl vinyl silicone rubber and white carbon, aluminium hydroxide, silicone oil, vulcanizing agent, its composition by weight is: methyl vinyl silicone rubber 20～50%, white carbon 20～57%, aluminium hydroxide 20～50%, silicone oil 2～5%, vulcanizing agent 1%.
Described end connection down is the fixed base frame of increasing.
The utility model has the advantages that: because end connection is the fixed base frame of increasing down, thereby the stability of plug and umbrella body and perpendicularity are improved, guaranteed that high-voltage alternating current isolating switch closes, the reliability of separating brake; Owing on following end connection, be provided with the sheath that links to each other with the umbrella body, thereby satisfied the requirement of insulation distance under the high pressure conditions; Strengthen the barred body of resin pultrusion because plug is an epoxy glass fiber, and be that material is made the umbrella body, thereby greatly reduce whole weight, improved the toughness and the anti-seismic performance of product with the high-temperature silicon disulfide rubber; Because rational in infrastructure, dependable performance is so there is very big practical and popularizing value.
