Description

A kind of insulator core precast body and insulator
Technical field
The utility model relates to power industry power transmission and transformation insulator technology fields, more particularly to a kind of insulator core Precast body and insulator.
Background technique
With extra high voltage line in China increasing year by year, the dosage of power transmission and transformation support insulator is consequently increased.It is existing The support insulator for having power transmission and transformation includes: that full porcelain type, porcelain core add the additional silicon rubber umbrella of silicon rubber umbrella skirt type, composite material inner core Skirt type.There are weight weights for full porcelain strut insulator, are easy to appear fracture and brittle failure, length increasing etc. lacks after voltage class improves It falls into.Porcelain core adds silicon rubber umbrella skirt t shore insulator there are external shed silastic materials Nian Jie with ceramic core loosely, generates bubble The phenomenon that, influence electric property and the service life of product.With the raising of power transmission and transformation voltage class, the additional silicon rubber of composite material inner core The dosage accounting of glue full skirt t shore insulator increases with it.
The plug of the additional silicon rubber umbrella skirt t shore insulator of composite material inner core is made of composite material, due to diameter It is larger, a pultrusion is difficult for pultrude process.The molding mode that the core of support insulator uses at present is mostly various The small drawing and extruding bar of specification bundles carry out overall perfusion, but such technique exists due to thinner more inner core rod structures Adhesive layer is excessive, and biggish area ratio is occupied in the cross-sectional area of core, and internal generation is biggish interior in solidification process The defects of stress, unbalanced stress causes inside to crack, is extremely difficult to ideal using effect in actual use.
The core of support insulator can also form in the following way: 1. inside be pultrusion plug, outer layer several times into Row winding.Although this molding mode can satisfy actual operation requirements, but production efficiency is lower, and outer layer need to be twined repeatedly It is more for the procedure calls in winding process around need to repeatedly solidifying, and it is larger to consume energy, substantially increase the manufacture of product at This.In addition, the mechanical property that fiber has certain abrasion to will be greatly reduced core during the winding process.2. another molding mode It is pultrusion plug for inside, outside is prepared into precast body by the techniques such as winding, weaving, rolling, integrally true using epoxy resin Empty form core.Though such mode substantially increases production efficiency and reduces the porosity defects of product, begin Exist eventually and generate interface between drawing and extruding bar and rear wrapper, forms layering hidden danger.
Though existing pillar insulator core using which kind of mode molded preforms, inside there is always an inner cores Then there is interface always in interior mandrel outer molded preforms, such inner core rod and outer layer subsequent forming part again in stick, and in this way Interface then will affect the electric property of product.
CN1731539A discloses a kind of preparation method of glass fiber impregnating resin wound-type composite insulator core: By glass fibre by the resin based sols after fusing, stirred evenly at 150 revs/min of revolving speed;Glass fibre and epoxy resin-matrix Solution curing molding after continuous winding at high temperature.The above method needs repeatedly winding, and production efficiency is low, waste of material is big. CN101740185A discloses the preparation method of major diameter composite insulator inner core rod: choose solid pultrusion insulation mandrel diameter≤ 130mm;The processing of plug outer surface is coarse, and outer surface is scrubbed with acetone, is put into constant temperature in baking oven;The re-coating of stick outer surface 2% absolute alcohol solution places into constant temperature 1 hour in baking oven;The configuration of resin glue weighs in proportion and pours into vacuum stirring It is stirred under vacuum 20 minutes in device, stands 50 minutes;The inner core rod of processing is installed to and starts to wind in numerical control winding machine, it is to be wound Machine is wound into design size;Then injection resin glue is vacuumized;Injecting glue, which finishes, closes both ends valve and is put into curing oven and heats rank Ladder solidification.The above method still uses canoe to prepare plug, so that glass fibre and inner core rod axially exist compared with mitre, The strength and stiffness of final products are not high.In addition, the surface treatment procedure of the above method is tediously long, curing process is unreasonable, still There is further improved space.
