Abstract
The invention discloses a large-diameter rod insulator mandrel which is characterized in that the mandrel (2) is provided with circular grooves (4) or thread grooves (5). The large-diameter rod insulator mandrel has the advantage that after the grooves on the mandrel (2) are solidified, under the effect of solidified binder, intensity between the grooves is increased further. Through detection of an FZSPW-1120/16 type 1120kV composite large-pillar insulator made of the mandrel, bending strength is 18-20kN, twisting strength is 22-26kN-m, tensile strength is 210-250kN, and compression strength is 1550-1800kN. The parameters are much higher than recommended parameter, and rate of finished products is improved from the original of about 80% to 90%-92%.
Description
Technical field
The invention belongs to the bar-shaped composite insulator technical field of using in the electric power T ﹠ D Technology field, definite saying is a kind of major diameter rod insulator plug.
Background technology
At present, make the major diameter rod insulator, such as large-diameter pillar insulator, owing to be subject to the restriction of material, need to adopt the combination plug through after certain PROCESS FOR TREATMENT, consist of large diameter plug, the application number of once applying for such as me is: 200920280937.3, name is called: a kind of combination core rod insulator namely discloses the insulator of this structure.But because the problem of plug itself, after curing, produce easily inner defects i.e.cracks, the requirement so that the physical indexs such as the tension of insulator, resistance to compression, bending resistance are arrived, and because the existence of these underbead cracks, so that the fabrication yield of major diameter composite insulator is lower, although taked a lot of innovative technologies, but, rate of finished products does not still reach 80%, so also so that the manufacturing cost of large-diameter pillar insulator is high, thereby have influence on quality and normal use of insulator.In order to address this problem, designer of the present invention has done in earnest research, has proposed goal of the invention of the present invention.
Summary of the invention
Defective and not enough the putting forward such as underbead crack that goal of the invention of the present invention exists in manufacture process in order to overcome present major diameter core rod of insulator.A kind of major diameter rod insulator plug namely is provided.
Technical solution of the present invention is achieved in that this major diameter rod insulator plug, it is characterized in that having cannelure (4) or thread groove (5) on the said plug (2).
Useful technique effect of the present invention is: the groove on the plug (2) under the effect of the binding agent that has solidified, has further increased intensity between groove and the groove after solidify.Through " the FZSPW-1120/16 type 1120kV composite post insulator " made by this kind plug detected bending strength: 18～20kN; Torsional strength: 22～26kNm; Hot strength: 210～250kN; Compressive strength: 1550～1800kN.The regulation that is much higher than recommended parameter, and rate of finished products brings up to 90%～92% by original less than 80%.
Description of drawings
Accompanying drawing 1 is mandrel structure generalized section of the present invention, and accompanying drawing 2 is the partial cutaway schematic with the spiral fluted plug, and accompanying drawing 3 is two plug arrangement architecture schematic diagrames, and accompanying drawing 4 is vertical views of accompanying drawing 2, mainly illustrates the planform of vertical slot.The rectangle of structure in the accompanying drawing 5,6,7,8 explanation plug, square, circular arc and the different cross section shape such as trapezoidal, be not only that the cross section is for circular, also can be according to the cross sectional shape in the accompanying drawing, perhaps further the planform in cross section is expanded to other geometric figures, as arc; arc triangle edge etc., all can think a concrete extension of the present invention.Sequence number in the accompanying drawings is: 1, cured layer, 2, plug, 3, outer cured layer, 4, cannelure, 5, helicla flute, 6, vertical slot.
Embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present invention and use are elaborated.With reference to accompanying drawing, this kind major diameter rod insulator plug is characterized in that having on the said plug (2) cannelure (4) that shows in the accompanying drawing 3.Perhaps has the thread groove (5) in the accompanying drawing 2.For the manufacturing needs of the post insulator that makes its suitable different size model, said plug is the epoxy resin rod.Perhaps said plug is the glass-epoxy rod.The size of plug can be the combination of sizes.
Simple and convenient in order to process, the cannelure on the said plug or thread groove form by the lathe turning cutting.
Make if produce in enormous quantities, the cannelure on the said plug or thread groove can be that die casting or cast form.
In order further to increase the intensity that mutually combines of plug, reduce the defectives such as underbead crack, have the vertical slot (6) that parallels to the axis in the outer surface increase of said plug.
Adopt one of this plug concrete implementer's case of making post insulator to be: the composite insulator plug that is formed by described a kind of major diameter rod insulator plug, it is characterized in that core rod of insulator inside has plug (2) by certain assembled arrangement as skeleton, has epoxy resin fiberglass cured layer (1) in the outside of this plug combined frame, the outer cured layer (3) of the epoxy resin that perhaps increases as required.Like this, after solidifying, the epoxy resin of filling in the middle of the cannelure on the plug or the thread groove solidifies two plugs adjacent to each other closely and connects as one, further, if with vertical slot, then after solidifying, its vertical slot and cannelure or thread groove have formed crisscross consolidated structures, so that the intensity of plug inside further strengthened, thereby overcome the deficiency that original because epoxy resin cure layer can only solidify at mandrel surface.Greatly improved the physical index such as tension, resistance to compression of post insulator.
Embodiment closer to practical application is: the composite insulator plug that is comprised of described a kind of major diameter rod insulator plug, it is characterized in that core rod of insulator inside has evenly distributed plug (2) as skeleton, has epoxy resin fiberglass cured layer (1) in the outside of this plug combined frame, the outer cured layer (3) of the epoxy resin that perhaps increases as required has the silicon rubber full skirt in the outside of epoxy resin cure layer (3).
