Background technology
In the last few years, China greatly developed electric utility, actively expanded transferring electricity from the west to the east scale, strengthened north and south interconnected and on national network, increase north, in, southern three major path ability of supplying electric powers, actively push forward long distance, Large Copacity power transmission, realize trans-regionally transmitting electricity across basin.For realizing this goal, must improve transmission voltage grade, building a collection of AC and DC UHV Transmission Engineering, namely exchange 750kV and 1000kV, direct current ± 800kV transmission line, its ability to transmit electricity comparatively exchanges 500kV and direct current ± 500kV transmission line improves several times.
Porcelain insulator is then the visual plant of high-tension electricity conveying, and it mainly plays insulation and fixing cord effect.Existing suspended porcelain insulator comprises insulator body, porcelain head and conductive cap.Porcelain head is fixed in insulator body, and conduction cap is located on porcelain head, and is fixed by bonding agent.On the one hand, the lifting surface area of bonding agent is little, and fixed effect is bad.On the other hand, because conductive cap adopts iron, silver or copper to become mostly, its cost is higher.Existing design is all towards the cost development reducing conductive cap, and the size of conductive cap and porcelain head are closely related, if the size of minimizing porcelain head, then can reduce the intensity of whole insulator; And in order to the intensity of whole insulator, then will certainly increase the size of conductive cap, thus increase cost.
Summary of the invention
Object of the present invention, providing a kind of microcephaly's suspended porcelain insulator head construction, to reduce the cost of conductive cap, reduces the manufacturing cost of enterprise.
In order to achieve the above object, base case of the present invention is: a kind of microcephaly's suspended porcelain insulator head construction, comprise porcelain head, conductive cap, wherein, described porcelain head is provided with screw thread, described screw thread is tapered thread, and described conductive cap and porcelain head threaded engagement, be provided with glue layer between described porcelain head and conductive cap.
Principle and the beneficial effect of this base case are: porcelain head and conductive cap are fixed together by threaded engagement by this programme, and are aided with adhesive and porcelain head and conductive cap are fixed further.On the one hand, by threaded engagement, add the bond area of adhesive, adhesive plays good fixed effect; On the other hand, because porcelain head is different from the material of conductive cap, then cause porcelain head different from the intensity of conductive cap, by the material that the fragile intensity of threaded engagement is low, and adhesive forms thin film between porcelain head and conductive cap, serve good isolation and cushioning effect, porcelain head or conductive cap can be avoided to damage.Screw thread is tapered thread, then this porcelain head is also taper, relative to common column porcelain head, can using one end less for taper as the size with the first sample of traditional porcelain, what then the part of conductive cap and the larger one end fits of porcelain head can be done is thinner, has saved raw material, thus has reduced cost.
Scheme two: based on this, scheme is preferred, the top center of described porcelain head is provided with anti-skidding projection, and described porcelain head is provided with the groove that projection anti-skidding with this is mated mutually.When porcelain head coordinates completely with conductive cap, anti-skidding projection just snaps in groove, prevents from further producing relative sliding between porcelain head and conductive cap.
Scheme three: this is the preferred of scheme two, described glue layer is cement glue.Relative to other adhesives, the insulating properties of cement glue is better.
Scheme four: based on this, scheme any one of scheme to scheme three is preferred, and described conductive cap is aluminum conductive cap.Relative to silver, copper, the conductivity of aluminum conductive cap is more or less the same, but the weight of aluminum conductive cap is lighter, less to the active force of porcelain head, can increase the intensity of porcelain head.Relative to iron, aluminum conductive cap is lightweight, and not easily gets rusty again, high life.
