The composite insulator comprises an upper cover (1), an upper connection (2), a silicon-rubber outer sleeve (3), an insulator body (4) and a pedestal (5), wherein the insulator body (4) is connected with the upper cover (1) through the upper connection (2), the silicon- rubber outer sleeve (3) is arranged outside the insulator body (4), the pedestal (5) is arranged below the insulator body (4), an inner core of the insulator body (4) is an epoxy-glass fiber rod, and the silicon-rubber outer sleeve (3) adopts a macromolecular polymer taking modified silicon rubber as the base material. The utility model has excellent electric insulativity, electric corrosion and ageing resistance, and good hydrophobic property enables the insulator to have great anti-dirtiness performance, therefore, the reliable operation of the electrical locomotive is ensured. An inner core of the insulator has good electric insulativity, mechanical property, shock absorption and creep deformation resistance, and the electrical strength, tensile strength and bending strength thereof are greatly superior to those of high-strength porcelain, so that the overall mechanical and electrical performances of the insulator are improved.
Description
Technical field
The utility model belongs to a kind of alternating current gasification railway locomotive special isolation, is specifically related to a kind of top high-voltage strut of electric locomotive composite insulator that is applicable to.
Background technology
At present, the porcelain insulators that adopt in the electric locomotive more, the whole mechanical electric performance of porcelain insulator is low, a little less than electrical insulation capability, electrocorrosion-resisting performance, ageing resistace, damping performance, the creep-resistant property, the electrical strength of porcelain insulator, tensile strength, bending strength, the dirty poor performance of resistant, the maintenance cost height, human input is bigger.
Summary of the invention
It is low that the utility model will solve the whole mechanical electric performance of porcelain insulator exactly, a little less than electrical insulation capability, electrocorrosion-resisting performance, ageing resistace, damping performance, the creep-resistant property, electrical strength, tensile strength, bending strength, the dirty poor performance of resistant, the maintenance cost height, the problem that human input is bigger.
The utility model is by the following technical solutions: a kind of top high-voltage strut of electric locomotive composite insulator that is applicable to, it comprise loam cake 1, on connect 2, silastic material 3, insulator 4, base 5; Insulator 4 is connected with loam cake 1 by last connection 2, is provided with silastic material 3 outside the insulator 4, and insulator 4 has base 5, and insulator 4 inner cores are the epoxy glass fiber rod, and it is the high molecular polymer of base material that silastic material 3 adopts modified silicon rubbers.
Compared with prior art, the utlity model has following beneficial effect:
1, to adopt modified silicon rubber be that the high molecular polymer of base material is made to silastic material, and silicon rubber has excellent electric insulation performance, electrocorrosion-resisting and ageing resistance.Particularly the hydrophobicity that silastic material is good makes insulator have the dirty performance of extremely strong resistant, and pollution flashover voltage improves 2～3 times than porcelain insulator, thereby has guaranteed the reliability service of electric locomotive.Silicon rubber insulator can clean in addition, avoids safeguarding, has reduced human input.
2, the insulator inner core is the epoxy glass fiber rod, has excellent electric insulating and mechanical performance.Its electrical strength, tensile strength and bending strength are better than high strength china greatly, have good damping property and creep resisting ability simultaneously, have improved the whole mechanical electric performance of insulator.
3, the utilization of advanced composite material (ACM) has alleviated product weight, compared with similar products, and weight saving 40%.In addition, the softness of silastic material and elasticity have guaranteed that product is easy to installation and transportation.
4, special adhesion process has been adopted in the product assembling, makes to have guaranteed the integral insulation performance by the reliable solid construction of the inner formation of insulator.
5, strengthened minimum arcing distance and creepage distance, made the product operation more safe and reliable.
