Abstract
The utility model relates to a synthetic insulation pull rod which belongs to components of high voltage switches in the technical field of the electric transmission and distribution. The utility model is characterized in that an end sleeve and an umbrella skirt are adhesively fixed to the outer side of a core rod, and the core rod is made from an epoxy spun glass guiding and dialing rod; so an insulator is formed. Connection hardware fittings are fixed to both ends of the core rod, and connecting rods are fixed on the connection hardware fittings. The utility model has the advantages that the mechanical performance is good, the anti-fatigue fracture performance is good, the toughness is good, the discharge performance is good even under a moisture condition, the anti-pollution flashover capacity is strong, the volume is small, the weight is light, the installation is convenient, and the utility model is difficult to damage.
Description
The utility model belongs to the parts of power transmission and transformation technical field mesohigh switch.
Development along with China's electric utility, more and more high requirement has been proposed for high-voltage switch gear reliability of operation, fail safe and life-span, in high-voltage switch gear, pull bar is the connector between action element and the driving mechanism, its end connects with electrified body, and an end connects with the earth, and it also works the transfer function of putting forth effort simultaneously, the electric power that driving mechanism is produced passes to the switch motion element, so pull bar must possess electric property and mechanical performance preferably; The pull bar that uses in the conventional switch all uses electroceramics to make, and at the indoor type switch of low-voltage grade the glass epoxide of use material is also arranged; These materials very easily take place to dodge the road under the wet condition of dirt, thereby cause the motionless or misoperation of switch, even it is destroyed together to connect driving mechanism; In addition, electroporcelain material " crisp " fractures easily, and is annual because the power outage that the problem of pull bar aspect causes occupies significant proportion.
The purpose of this utility model provides a kind of power outage that reduces, the composite insulation pull bar that pollution flashover voltage and mechanical performance are all good.
The technical scheme that realizes the utility model purpose is, the utility model comprises connecting rod, the insulator that connects gold utensil and plug, end cover, full skirt composition, plug is made by the epoxy glass fiber leading-drawing rod, the master bears mechanical load and interior insulation, end cover and full skirt are formed through hot-press vulcanization in mould by the high molecular polymer that with silicon rubber or ethylene-propylene rubber is matrix, closely are bonded in the plug outside with special bonding agent, do not have air gap therebetween; Connect gold utensil and made by steel or aluminium alloy, on crimping, riveted joint, the bonding two ends that are fixed in plug 4, connecting rod is fixed on the connection gold utensil with the mode of screw thread, and compresses with nut; Its two ends seal with bonding agent.
Adopt the composite insulation pull bar of said structure, its advantage is: 1. good mechanical property, and tensile strength is higher 3～4 times than porcelain pull bar, and the fatigue crack-resistant performance is good, good toughness; 2. the discharge performance under the dirty wet condition is good, and anti-soil sudden strain of a muscle ability is strong, is 2～4 times of porcelain pull bar, is difficult for taking place flashover; 3. volume is little, in light weight, installation and transportation convenience, not cracky; 4. make simply the rate of finished products height.
Accompanying drawing is an outline drawing of the present utility model.
Be that embodiment further specifies the utility model below with the accompanying drawing:
The utility model is made up of connecting rod 1, connection gold utensil 3 and insulator, insulator comprises plug 4, end cover 6 and full skirt 5, plug 4 is made by the epoxy glass fiber leading-drawing rod, mainly bear mechanical load and interior insulation, the size and the length of its diameter are selected according to actual needs, end cover 6 and full skirt 5 are formed through hot-press vulcanization in mould by the high molecular polymer that with silicon rubber is matrix, be adhesively fixed on the outside of plug 4 with special bonding agent, there is not air gap therebetween, constitute the insulated part of composite insulation pull bar, have good hydrophobicity, arc resistant, ageing resistace; Connect gold utensil 3 usefulness steel or aluminium alloy and make, adopt crimping, riveted joint, bonding, or several mode is used with, be fixed in the two ends of plug 4, carry out the transmission of power, the mode of connecting rod 1 usefulness screw thread screws in and connects in the gold utensil 3, and compress with nut 2, its two ends seal with special bonding agent.
