Description
Technical field
The utility model is related to porcelain insulator correlative technology field, more particularly to the multilayer steps suspension type porcelain of a kind of high intensity
Insulator.
Background technology
Porcelain insulator is generally risen in high-tension overhead line absolutely using a kind of most universal and most important line insulator
Edge and fixed function are mainly made of chapeau de fer, steel feet, the porcelain piece with full skirt with adhesive, and porcelain insulator is the weight of transmission line of electricity
Component part is wanted, is electrical insulations and important structural support, the insulation performance and mechanical performance of porcelain insulator and its is matched
The reasonability set directly affects the safe and stable operation of circuit, is mainly in the load of mechanical properties, porcelain insulator
It is axial and partially radially on tensile load, what line insulator will bear to be determined by conducting wire and dead weight and its wire tension
Tensile stress, and the variation of strong wind, icing and its temperature can also make suffered pulling force become larger.Insulator is also possible to bear a variety of
Transient state load, conductor vibration or wave can all so that insulator bears an oscillating load, under natural environment as climb wind,
It shakes, the coating ice falling etc. of conducting wire, so that insulator is born a shock loading, act on the mechanical load master on porcelain insulator
It to be born by chapeau de fer, steel feet, porcelain piece and their mutual adhesives, currently, existing suspended porcelain insulator structure is strong
Degree is not high, and security and stability, service life etc. have to be hoisted.
Utility model content
For the above-mentioned prior art the problem of middle porcelain insulator, the utility model provide it is a kind of it is reasonable for structure,
Safety and stability, tensile strength height, multilayer steps suspended porcelain insulator with long service life.
The technical problems to be solved in the utility model is adopted the technical scheme that：A kind of multilayer steps suspension type porcelain insulating
Son, including cohesive chapeau de fer, porcelain piece, steel feet successively from top to bottom, are provided with outer cementing layer between the chapeau de fer and porcelain piece, described
It is provided with interior cementing layer between porcelain piece and steel feet, connecting plate is provided in the chapeau de fer, connecting hole is provided on connecting plate, it is described
The first full skirt and the second full skirt are provided in porcelain piece, it is 30-60 ° that the second full skirt, which is tilted with horizontal angle, the steel feet top
Portion is provided with axial notch, and upper ring is disposed with from top to bottom in an axial direction on the steel feet outer surface in stretching into interior cementing layer
Platform, middle land and lower land, the outer diameter of the upper land, middle land and lower land are sequentially increased, and the lower land outer diameter is little
In twice of steel feet diameter.
Further, the cross section of the axial notch is cross or linear type.
The utility model is compared with prior art, recessed by the way that ring shaped axial is respectively set at the top of steel feet and outer surface
Slot, several land so that the connection stress between steel feet, porcelain piece and interior cementing layer increases, and overall performance is improved, and solves
Porcelain insulator is insecure in axially connection and steel feet is caused to loosen the problem of even causing overall deformation.
Description of the drawings
Fig. 1 is the main section view structure schematic diagram of the utility model.
In the figure 1, chapeau de fer 2, connecting hole 3, connecting plate 4, axial notch 5, upper land 6, middle land 7,
Lower land 8, steel feet 9, interior cementing layer 10, the second full skirt 11, the first full skirt 12, outer cementing layer 13, porcelain piece.
Specific implementation mode
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below according to attached drawing in conjunction with next
The utility model is described in further detail.
As shown in Figure 1, a kind of multilayer steps suspended porcelain insulator, including cohesive chapeau de fer 1, porcelain successively from top to bottom
Part 13, steel feet 8 are provided with outer cementing layer 12, interior gluing are provided between the porcelain piece and steel feet between the chapeau de fer and porcelain piece
Layer 9 is provided with connecting plate 3 in the chapeau de fer, connecting hole 2 is provided on connecting plate, the first full skirt 11 is provided in the porcelain piece
With the second full skirt 10, the first full skirt is substantially parallel with horizontal line, and the second full skirt tilts in a certain angle with horizontal line（30-60°）,
It is provided with axial notch 4 at the top of the steel feet, is set successively from top to bottom in an axial direction on the steel feet outer surface for stretch into interior cementing layer
Be equipped with land 5, middle land 6, lower land 7, the outer diameter of the upper land, middle land and lower land is sequentially increased, with in cone
The interior cementing layer of shape is corresponding, and upper land, middle land and lower land longitudinal section are arc-shaped, are trapezoidal or rectangular, the lower land
Outer diameter is not more than twice of steel feet diameter.The upper land 5, middle land 6, lower land 7 are all contained by interior cementing layer, most parcel
Hold thickness and be not less than 3-5 millimeters, to better adapt to the drawing force of connecting wire in different directions.
Preferably, in order to further more in cementing layer and steel feet bonding strength, the cross section of the axial notch is
Cross or linear type.
Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although with reference to specific embodiment
The utility model is described in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the utility model
Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of technical solutions of the utility model, should all be covered
In the protective scope of the claims of the utility model.
