Abstract
The utility model provides a bell jar type exchanges resistant dirty disk suspension type and exchanges porcelain insulator, including steel cap, porcelain spare, slot and steel foot, bond through the glue between steel cap, porcelain spare and the steel foot, steel cap, steel foot are equipped with the one deck buffer layer with glue contact surface, the buffer layer is silicon sulfide rubber layer. The full skirt edge of porcelain spare is inside bury underground with porcelain spare coaxial, be used for improving the shield ring of insulator along face field distribution, the shape of shield ring is consistent with the marginal shape of the full skirt of porcelain spare. Through adopting the silicon sulfide buffer layer, increase substantially the disk suspension type bell jar type that exchanges porcelain insulator and tremble ripples endurance, disk suspension type bell jar type insulator have under the 1V filth good resistance to soiling can, under the close and grey close condition of the same salt, the resistant pollution flashover ability of disk suspension type bell jar type insulator is 1.8 times of ordinary disk suspension type bell jar type insulator at least.
Description
Technical field
The utility model relates to a kind of insulator used for transmission line, particularly relates to a kind of bell-shaped and exchanges resistant disc suspension Porcelain insulator.
Background technology
Cap and pin insulator is a kind of insulator for transmission line, in all kinds of line insulator, cap and pin insulator be main, be simultaneously also the maximum one of consumption.Insulator is mainly used in overhead transmission line, plays insulation and hangs wire.Insulator mainly bears the comprehensive function of the factors such as pulling force, vibration, system voltage, overvoltage and various atmospheric conditions in use.Insulator structure can be divided into tip portion and insulating part full skirt two parts.Insulating part full skirt and the insulator visible part except tip portion, insulating part full skirt is generally in disc.Insulator tip portion mainly gives insulator mechanical strength and interior insulation property, and insulating part full skirt part mainly gives insulator external insulation performance.
Insulator is positioned in open-air atmosphere, when there is the meteorological condition such as sleet, snow melt in the winter time in the transmission line of northern provinces and cities, there will be insulator string and slipped bridge joint phenomenon by ice, the dielectric strength of the insulator string be bridged significantly reduces, as easy as rolling off a log generation flashover fault, therefore needs the structure of insulator to do and improves to improve its stabilization ripple tolerance a bit.
Utility model content
The technical problems to be solved in the utility model, be to provide a kind of structure simple disc suspension Porcelain insulator, that can improve insulator trembles ripple tolerance.
The utility model is achieved in that a kind of bell-shaped exchanges resistant disc suspension Porcelain insulator, comprise steel cap, porcelain piece, groove and steel pin, bondd by adhesive between steel cap, porcelain piece and steel pin, described steel cap, steel pin and adhesive contact surface are provided with one deck resilient coating, and described resilient coating is sulphurated siliastic layer; The inside, full skirt edge of described porcelain piece be embedded with coaxial with porcelain piece, for improving the shading ring of insulator along face Electric Field Distribution, the shape of described shading ring is consistent with the full skirt edge shape of porcelain piece.
Wherein, described porcelain piece and described groove are all enclosed with the thick sulphurated siliastic layer of 5mm.
Wherein, the head of described porcelain piece is columniform.
Wherein, the porcelain piece head facade position of described cylindrical porcelain adopts wave structure.
Wherein, the dish footpath of described insulator is 400mm, and the creepage distance of insulator is 550mm.
The utility model has the advantage of:
By adopting described silicon sulfide resilient coating, increase substantially interchange disc suspension bell-shaped porcelain insulator and tremble ripple tolerance, disc suspension bell-shaped insulator has good anti-pollution characteristic under 1V filth, close with under the close condition of ash at identical salt, the resistance to pollution flashover ability of disc suspension bell-shaped insulator is at least 1.8 times of common disc suspension bell-shaped insulator; Improve the situation of insulator along face non-uniform electric after introducing shading ring, effectively reduce insulator surrounding electric field intensity, thus suppress flashover and the generation punctured, increase substantially the insulation property of insulator.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model bell-shaped exchanges resistant disc suspension Porcelain insulator.
Label declaration:
Steel cap-1 porcelain piece-2 groove-3 steel pin-4 resilient coating-5 sulphurated siliastic layer-6 shading ring-7.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Consult shown in Fig. 1, a kind of bell-shaped of the present utility model exchanges resistant disc suspension Porcelain insulator, comprise steel cap 1, porcelain piece 2, groove 3 and steel pin 4, steel cap 1, bondd by adhesive between porcelain piece 2 and steel pin 4, described steel cap 1, steel pin 4 and adhesive contact surface are provided with one deck resilient coating 5, described resilient coating 5 is sulphurated siliastic layer, the inside, full skirt edge of described porcelain piece is embedded with porcelain piece coaxial, for improving the shading ring 7 of insulator along face Electric Field Distribution, the shape of described shading ring 7 is consistent with the full skirt edge shape of porcelain piece, the cross section of described shading ring 7 can be circular or oval.Improve the situation of insulator along face non-uniform electric after introducing shading ring 7, effectively reduce insulator surrounding electric field intensity, thus suppress flashover and the generation punctured, increase substantially the insulation property of insulator.Bell-shaped exchanges resistant disc suspension Porcelain insulator high-temperature silicon disulfide rubber and does resilient coating 5, interchange disc suspension bell-shaped porcelain insulator can be increased substantially and tremble ripple tolerance, can by being examined by 2.85 times of negative polarity lightning impulse voltages according to amplitude method.Silicone rubber formulations is unique, technique is advanced, the sulphurated siliastic resilient coating 5 formed is determined through artificial pollution experiment, the insulator of disc suspension bell-jar has good anti-pollution characteristic under the filth of 1V level, under the condition that identical salt is close and ash is close, the durability against pollution of the bell-shaped cap and pin insulator of present embodiment is 1.8 times of common bell-shaped insulator.
In above-mentioned execution mode, preferred described porcelain piece 2 and described groove 3 are all enclosed with the thick sulphurated siliastic layer 6 of 5mm.The sulphurated siliastic layer 6 of 5mm is comparatively reasonable on thickness, and is easy to production and processing, and when the thickness of described sulphurated siliastic layer 6 is 5mm, its anti-pollution characteristic is better.The head of described porcelain piece 2 is columniform, and the head of described porcelain piece 2 is not only restricted to columniform, and such as conical or other shapes all can be applied in above-mentioned execution mode.In order to increase the frictional force between adhesive and porcelain piece 2, the porcelain piece 2 head facade position of described cylindrical porcelain adopts wave structure.The dish footpath of described insulator is 400mm, and the creepage distance of insulator is 550mm, and the dish footpath of setting insulator and creepage distance, control the size of described insulator, make its performance better.
The embodiment that the utility model bell-shaped exchanges resistant disc suspension Porcelain insulator is only described in upper; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
