Abstract
The utility model discloses a composite hollow supporting post insulator for a high-speed railway. A glass fiber reinforced plastic insulation cylinder is formed by winding of fiber glass filaments and epoxy resin; an upper connection support seat is installed at the upper end of the glass fiber reinforced plastic insulation cylinder by a gluing way; and a lower connection support seat is installed at the lower end of the glass fiber reinforced plastic insulation cylinder by a gluing way. The upper connection support seat and the lower connection support seat are connected with the glass fiber reinforced plastic insulation cylinder by flanges. The flanges are provided with flange inner rings and flange outer rings; and the flange inner rings and the flange outer rings are respectively connected to the inner surface and the outer surface of the glass fiber reinforced plastic insulation cylinder by a gluing way with organic high-strength materials. Besides, the inside of the glass fiber reinforced plastic insulation cylinder is filled with a low-density high-polymer insulating material; a group of air bags is arranged in the low-density high-polymer insulating material; and the outer surface of the glass fiber reinforced plastic insulation cylinder is provided with a silicone rubber parachute sleeve by an integrated mould pressing way. The provided insulator has the characteristics of long dry arcing distance, good antifouling property, light weight, good rigidity, and low cost and is suitable for the high-speed railway.
Description
Technical field
The utility model relates to a kind of composite post hollow insulator, is specifically related to a kind of used for high-speed railway composite post hollow insulator.
Background technology
Along with the fast development of China railways cause, increasing high-speed railway starts build and put into operation, and the post insulator for high-speed railway circuit mainly contains two kinds at present:
1, porcelain strut insulator, its major defect is Heavy Weight, and the hydrophily of insulator causes forming continuous moisture film on overcast and rainy insulator surface, especially in heavy pollution area, the probability that makes insulator surface that flashover occur increases greatly.
2, compound solid core insulator, its major defect be poor in rigidity, cost is high.
Summary of the invention
In order to overcome the shortcoming of existing high-speed railway post insulator, the purpose of this utility model is to provide a kind of used for high-speed railway composite post hollow insulator, and this composite post hollow insulator can effectively improve integral bending and insulation property, reduces costs.
The purpose of this utility model is achieved through the following technical solutions:
A kind of used for high-speed railway composite post hollow insulator, it is characterized in that: this hollow insulator comprises connecting support seat, glass fibre reinforced plastic insulating cylinder, silicon rubber skirt cover, low-density insulating polymeric material, air bag and lower link bearing, and described glass fibre reinforced plastic insulating cylinder is entwined by glass fiber and epoxy resin; On glass fibre reinforced plastic insulating cylinder upper end mucilage binding has connecting support seat, in glass fibre reinforced plastic insulating cylinder lower end, mucilage binding has lower link bearing; Upper connecting support seat is all connected with glass fibre reinforced plastic insulating cylinder by flange with lower link bearing; Flange is provided with ring and flange outer shroud in flange, in this flange, encircle and flange outer shroud respectively with glass fibre reinforced plastic insulating tube inner surface and organic Materials with High Strength mucilage binding for outer surface; In glass fibre reinforced plastic insulating cylinder inside, be filled with low-density insulating polymeric material; In low-density insulating polymeric material, be provided with one group of air bag; At glass fibre reinforced plastic insulating tube outer surface integral die, there is silicon rubber skirt cover.
In the utility model, in flange, the height of ring is higher than the height of flange outer shroud.In flange, the height of ring and the aspect ratio of flange outer shroud are 1.2:1.
The utlity model has mechanical strength high, the advantages such as electrical insulation properties, moistureproof anti-weathering aging function admirable.Integral bending and insulation property have greatly been improved; Can also be able to improve anti-soil sudden strain of a muscle level.The utility model is applicable in high-speed railway.
