Abstract
The utility model relate to a cross-arm composite insulator and mainly solves a technical problem of easy fracture of a porcelain cross-arm in a use process caused by poor bending resistance strength of a cross-arm composite insulator in the prior art. The cross-arm composite insulator comprises a core rod, a protection sleeve, an umbrella skirt and connection metal tools, wherein the connection metal tools comprises a steel pin and a steel cap, the steel pin and the steel cap are respectively arranged at two ends of the protection sleeve, the umbrella skirt is prepared by silicone rubber and is in integration connection at a periphery of the protection sleeve, and the core rod is prepared by epoxy resin glass fiber and is accommodated at an inner portion of the protection sleeve. A composite suspension insulator is applicable to use in a filthy area, by utilizing three parts of the epoxy resin glass fiber core rod, the silicone rubber umbrella skirt and the metal tools, reliability and production efficiency of the composite insulator are effectively improved, and the cross-arm composite insulator has advantages of high strength, small volume and light weight.
Description
Technical field
The utility model relates to a kind of insulator, refers in particular to a kind of cross-arm composite insulator that is installed on the porcelain pole arm.
Background technology
Along with development of science and technology, insulator plays two basic roles in overhead transmission line, it is support wire and prevent that electric current from going back to ground, these two effects must be guaranteed, insulator should be owing to environment and the electric loading condition various dynamo-electric stress that causes that changes lost efficacy, otherwise insulator just can not produce great function, will damage use and the service life of whole piece circuit.At present, the cross-arm composite insulator is being installed on the porcelain pole arm, and in use, because the influence of external environment, cross-arm composite insulator amplitude of fluctuation is bigger, therefore, easily causes the impaired influence of porcelain pole arm to use.
Summary of the invention
For shortcoming and the weak point that overcomes background technology, the utility model provides a kind of cross-arm composite insulator, solves existing cross-arm composite insulator because anti-bending strength is relatively poor, therefore in use easily causes the technical problem of porcelain pole arm fracture.
The technical solution of the utility model is: a kind of cross-arm composite insulator comprises sheath, exhausted
Edge plug and full skirt, the two ends of described sheath are provided with the gold utensil that matches with insulation mandrel, and the sheath inboard is made and be socketed on to described insulation mandrel by the ethylene-propylene rubber material.
Described full skirt is made and is obliquely installed in the sheath periphery by epoxide resin material.
Described full skirt is evenly distributed along sheath.
Described gold utensil is provided with step trough, and described sheath is provided with the Ka Tai that cooperates with described step trough clamping.
The utlity model has following beneficial effect: because this cross-arm composite insulator adopts counter-bending structure; in use bending property is stronger; effectively avoid porcelain pole arm to be damaged and caused phenomenon of rupture, better played the effect of protection, improved useful life and the serviceability of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place structure enlarged drawing among the utility model Fig. 1.
Among the figure, sheath 1, insulation mandrel 2, full skirt 3, gold utensil 4, step trough 5, card platform 6.
Embodiment
At accompanying drawing embodiment of the present utility model is described further below:
Shown in figure, a kind of cross-arm composite insulator comprises sheath 1, insulation mandrel 2 and full skirt 3, and the two ends of described sheath 1 are provided with the gold utensil 4 that matches with insulation mandrel 2, and sheath 1 inboard is made and be socketed on to described insulation mandrel 2 by the ethylene-propylene rubber material.According to such scheme, because this cross-arm composite insulator adopts counter-bending structure, in use bending property is stronger, has effectively avoided porcelain pole arm to be damaged and has caused phenomenon of rupture, better plays the effect of protection, improves useful life and the serviceability of product.
In the utility model, described full skirt 3 make and be obliquely installed by epoxide resin material in
In the utility model, described gold utensil 4 is provided with step trough 5, and described sheath 1 is provided with the card platform 6 that cooperates with described step trough 5 clampings, and the connective stability height effectively improves the serviceability of product.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
