Abstract
The utility model relates to a synthetic insulator which is used for electrical insulation and particularly be used for contact hangings in low clearance tunnels of electric railways. The insulator of the utility model adopts an integral tubular sheath which is made of polytetrafluoroethene, and the sheath is provided with a smooth surface (replaces the original umbrella skirt-shaped insulator sheaths). The sheath is sheathed on a core rod which is made of 811-typed glass fibre epoxy resins.
Description
The utility model is used for electric insulation, especially for a kind of novel composite insulator of contact suspension in the electric railway low headroom tunnel.
The present both at home and abroad composite insulator that adopts, E-01 type epoxy resins insulation for example, material is easily aging, and processing technology exists technological deficiencies such as cracking.Faults such as easy as rolling off a log generation dielectric surface flashover and internal breakdown cause that contact line has a power failure, and cut off traffic the influence transportation.And general insulator mostly is the form of band full skirt.Though this kind shortened the structure length of insulator,,, reduced the useful life of insulator so reduced the anti-soil withstand voltage properties of insulator owing to easily pollute.The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of composite insulator both to satisfy the leakage distance of insulator, improved insulation property, prolonged its useful life again.
Accompanying drawing 1 is electric insulation composite insulator schematic diagram.1 is the connection steel cap of insulator among the figure, and 2 is the bonding agent between steel cap and plug, and 3 is the polytetrafluoroethylene sheath, and 4 is filler, and 5 is plug, and 6 is rivet.
The utility model characteristics are that the sheath (3) of insulator has adopted good insulation preformance, and high-and low-temperature resistance performance, corrosion resistance and good have self-lubricating again, and the synthetic material polytetrafluoroethylene of viscosity is not made.Replaced the aging easily epoxy resin of original material.Sheath changes ganoid integral cannula into by general umbrella-skirt type.
Now 1 describe embodiments of the invention in detail in conjunction with the accompanying drawings:
The plug of this composite insulator (5) is to be processed by 811 type glass fibre epoxy spike pullings.Behind plug (5) the suit sheath (3), dry, vacuumize, between plug (5) and sheath (3), insert filler (4) filler then and adopt epoxy resin.The length of plug (5) is greater than sheath (3).Plug (5) two ends embed the steel insulator pin joint and adopt epoxy resin to carry out bonding.As after scheming assembling, fix with rivet.
The utility model compared with the prior art has good insulating properties. Greatly improved the service life of insulator, simple in structure, easy to maintenance. If be used for the tunnel, can reduce the head room that the contact suspension structure takies. Reduce cost, for contact net keeps in repair less, freedom from repairs creates favorable conditions.
Claims (3)
1, a kind of composite insulator that is used for electric insulation, be made up of plug, sheath and union piece, the sheath (3) that it is characterized in that insulator is the ganoid integral cannula of being made by polytetrafluoroethylene.
2, according to the described insulator of claim 1, it is characterized in that plug (5) adopts 811 type glass fibre epoxy spike pullings to make, the two ends of plug (5) are connected steel cap (1) with binding agent (2) with insulator bonding.
