Abstract
A traditional post insulator is made of glass or ceramic. In cloudy, rainy, and foggy conditions, flashover of a surface of the insulator easily happens to cause an accident. On the other hand, according to an existing post insulator, a core post end and a metal accessory of a post are usually connected through adhesion. When a post torque requirement is large, a structure often does not reach the standard. The utility model provides a combined post insulator which comprises an umbrella skirt, a core rod, a fixed flange and a screw hole, wherein the umbrella skirt is formed by high temperature vulcanization of polymeric material with silica gel as a matrix, the umbrella skirt is pasted to an external surface of the core rod through a bonding agent, and a lower end of the core rod is embedded with the fixed flange which is provided with the screw hole. The combined post insulator has excellent anti-pollution performance, flashover voltage is larger than that of a common ceramic post insulator by 2 to 3 times, the lower end of the core rod is embedded with the fixed flange, the metal accessory is connected with the fixed flange through the screw hole, and mechanical strength and torsion resistant capacity are raised.
Description
Technical field
The utility model relates to insulator and makes the field, relates in particular to a kind of combination post insulator.
Background technology
Post insulator is a kind of special insulation control, can play an important role in overhead transmission line.Traditional post insulator is generally made by glass or pottery.Because its antifouling ability is relatively poor, behind the surface deposition dirt, insulation level can descend, and particularly descends in the moon, rain, mist condition, and pollution flashover occurs easily on the surface, causes the accident.On the other hand, existing post insulator passes through bonding connection between the stem stem end of its pillar and the metal-ware usually, although have simple in structure, easily manufactured having a few, but its anti-twisting property is poor, and when requiring the pillar moment of torsion larger, this structure is often not up to standard.
The utility model content
For existing technical problem, the utility model provides a kind of combination post insulator, and it can prevent pollution flashover accident effectively, mechanical strength is high, anti-twisting property is strong.To achieve these goals, technical solution adopted in the utility model is, a kind of combination post insulator comprises full skirt, plug, mounting flange, screw hole, wherein, full skirt for the macromolecule polymeric material take silica gel as parent through high temperature vulcanized forming; Full skirt is by the sticking outer surface that is posted on plug of binding agent; The plug lower end is inlaid with mounting flange, digs screw hole on the mounting flange.
A kind of combination post insulator that the utility model provides, preparation technology is simple, good insulating, mechanical strength are high, have excellent antifouling performance, pollution flashover voltage than the general large 2-3 of porcelain pillar insulator doubly, the plug lower end is inlaid with mounting flange, metal-ware is connected with mounting flange by screw hole, has improved mechanical strength and anti-twisting property.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, full skirt, 2, plug, 3, mounting flange, 4, screw hole
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model, comprises full skirt 1, plug 2, mounting flange 3, screw hole 4, and wherein, full skirt 1 is high temperature vulcanized the forming of the process of the macromolecule polymeric material take silica gel as parent; Full skirt 1 is by the sticking outer surface that is posted on plug 2 of binding agent; Plug 2 lower ends are inlaid with mounting flange 3, dig screw hole 4 on the mounting flange 3.A kind of combination post insulator that the utility model provides, preparation technology is simple, good insulating, mechanical strength are high, have excellent antifouling performance, pollution flashover voltage than the general large 2-3 of porcelain pillar insulator doubly, plug 2 lower ends are inlaid with mounting flange 3, metal-ware is connected with 4 mounting flanges 3 by screw hole, has improved mechanical strength and anti-twisting property.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; with not being restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
