Abstract
The utility model relates to an electrical switch box insulating device and a generator switch. The utility model is characterized in that a heat-resisting layer (such as polytetrafluoroethylene, PFA or perfluorinated ethylene-propylene copolymer) is fixedly connected with the matrix of the insulating device, wherein the glass transition temperature of the heat-resisting layer is at least 100 DEG C and preferably at least 115 DEG C. The thickness of the heat-resisting layer (1) is smaller than 3mm. The heat-resisting layer (1) and the matrix (7) of the insulating device are connected together through first plastic.
Description
Technical field
The utility model relates to the field of electrical insulation device, in particular for the field of the electrical insulation device of medium-voltage equipment and high-tension apparatus.The utility model relates to the manufacture of seal and this seal with refractory layer.
Background technology
Electrical insulation device often has the material of thermal sensitivity, for example plastics.When this seal is used in the environment of short-term warming at least, described seal must be by the protection of refractory layer heat, to for example avoid reducing of mechanical failure that the carbonization by plastics causes and dielectric strength.
Utility model content
Task of the present utility model is, provide a kind of electrical insulation device for, described seal is heat-resisting.
First aspect of the present utility model is the electrical switch box seal for generator contactor, described switch-box seal has seal matrix and the refractory layer being fixedly connected with described seal matrix, it is characterized in that, the thickness of described refractory layer is less than to be realized being connected by the first plastics between 3mm and described refractory layer and described seal matrix.
Further, described the first plastics are adhesives.
Further, the side towards described seal matrix of described refractory layer is corroded, to improve the wetting of described corrosive side by adhesive.
Further, described seal matrix has the second plastics, it is characterized in that, described the second plastics are epoxy resin.
Further, described refractory layer has polytetrafluoroethylene or perfluoro alkoxy.
Further, described seal matrix is comprised of the plastics that strengthen with aramid fibre.
Second aspect of the present utility model is a kind of generator contactor, it is characterized in that, described generator contactor comprises above-mentioned electrical switch box seal.
Theme of the present utility model is, vitrification point is at least 100 degrees Celsius, be preferably at least the refractory layer (for example polytetrafluoroethylene, perfluoroalkoxy or perfluoroethylene-propylene copolymer) of 115 degrees Celsius is fixedly connected with seal matrix, and the thickness of described refractory layer is less than to be realized being connected by the first plastics between 3mm and described refractory layer and described seal matrix.This makes it possible to that described seal matrix is carried out to material and effectively protects.
Accompanying drawing explanation
Next according to embodiment, further illustrate by reference to the accompanying drawings the utility model.
Fig. 1 illustrates has the surperficial refractory layer that is corroded;
Fig. 2 & 3 illustrates for the manufacture of heat cured seal matrix and by being wound around (Wickeln), carrys out the method step of connection insulator matrix and refractory layer simultaneously; And
Fig. 4 illustrates the seal with refractory layer.
The reference marker using is in the accompanying drawings summarized in list of reference signs.Substantially, identical part is marked by same reference marker.
Embodiment
Fig. 1 illustrates the refractory layer 1 of being made by PFA.One side of described refractory layer 1 is corroded with sodium metal.
Fig. 2 illustrates the winding mandrel (winkeldorn) 4 for heat cured wet type winding method.Refractory layer 1 is placed on and is wound around on mandrel 4 and is therefore formed in side closed in the circumferential direction that is wound around mandrel 4.At this, described layer 1 side being corroded deviates from described winding mandrel 4.
Fig. 3 illustrates the fortifying fibre 5 adopting through dipping and in corrosive side, the refractory layer 1 being placed on described winding mandrel 4 is wound around, and described fortifying fibre 5 state with sclerosis after being wound around forms seal matrix 7.At this, described fortifying fibre 5 passed through epoxy resin impregnated by means of immersion system 6 before being wound around.Continue described winding until draw the desired shape of described seal matrix 7 always.Therefore by the fortifying fibre 5 through dipping is wrapped in the corrosive side of described refractory layer 1, apply unnecessary epoxy resin and between described refractory layer and described seal matrix, there is the joint face of adhesive wetted.After described epoxy cure, complete bondingly, between the refractory layer 1 in inner radial and the seal matrix 7 at the hollow cylinder bodily form of radially outer, form and connect thus.The seal of so manufacturing is especially favourable as the heating chamber seal for generator contactor.
At this, the kind of described fortifying fibre 5 and orientation can change.Therefore by prepreg (Prepregs), as fortifying fibre 5, be for example, possible.For guaranteeing that refractory layer 1 passes on winding mandrel 4 in circumferential direction, can in circumferential direction, be wound around described refractory layer 1 until the end edge of the start edge of described layer 1 and described layer 1 forms overlapping around described winding mandrel 4.As alternative, described start edge and end edge can be placed directly on joint (Stoss) above and adopt additional the bringing of described refractory layer 1 to cover described joint.Therefore, can avoid there is the gap that is filled with epoxy resin between described start edge and described end edge, the gap that is filled with epoxy resin becomes conductive by the relevant carbonization meeting of heat.Replace wet type winding method, can also use the dry type winding method that adopts follow-up injection dipping.
Fig. 4 illustrates seal, this seal have seal matrix 7 with described seal matrix 7 by the bonding refractory layer being connected 1.The side 3 towards described seal matrix 7 of described refractory layer 1 is corroded.
