Description

A kind of erecting device of conducting rod

Technical field

The utility model relates to the erecting device technical field of conducting rod, is particularly useful for high pressure, ultra high voltage, EHV bushing assembly technology.

Background technology

At present, electric pressure rising along with high voltage electric equipment, the creepage distance of line porcelain bushing (composite bushing) and insulation distance also increase thereupon, the diameter of corresponding porcelain bushing and length also increase thereupon, diameter as 1,000,000 volts of line porcelain bushings reaches more than one meter, and length reaches tens meters long especially.in the porcelain bushing of this length when conducting rod is installed, the phenomenon that exists conducting rod " to bow ", general solution has following two kinds: a kind of method is directly in the end of conducting rod, to increase the sheath of being made by flexible material, with sheath, with internal surface of sleeve pipe, contact, although this method sheath is simple in structure, but between sheath and porcelain bushing, there is larger friction, in the process that sheath moves with conducting rod, the end of conducting rod usually can be from exposing sheath, so that sheath is not in place to the protection of conducting rod, make the end of conducting rod directly to contact with the inwall of porcelain bushing, finally cause the inwall of porcelain bushing to scratch, another kind method is to use a jigger to hold conducting rod at inside pipe casing, avoid the end of conducting rod and the inwall of sleeve pipe to collide with, this method is no doubt simple, but in use, jigger can only be avoided the collide with inwall of porcelain bushing of the end of conducting rod, can not help conducting rod centering and location, in follow-up assembly work, the centering and the location that also need other means to assist, this has just increased the labour intensity of conducting rod assembling.

it is a kind of for GIS three-phase non-segregated bus conducting rod frock guide car that notification number is that the Chinese utility model patent of CN202363840U discloses, the discoid guide body and the positioning disk that before and after this guide car comprises, distribute successively, the connecting rod that guide body and positioning disk extend by front and back coaxially is connected, the relative conductor bores that offers for passing for conducting rod to be installed on guide body and positioning disk, on the hole wall of conductor bores, be evenly equipped with several trundles, and on the periphery of guide body several big rollers, so that guide body is coaxially slipped in the endoporus of bus bar canister, guarantee that on conductor bores and the bus bar canister on guide body and positioning disk, the touch base on disk insulator is relative, but the continuous increase along with the bus bar canister caliber, guide body on corresponding this guide car and the diameter of positioning disk also need corresponding increase, thereby make whole guide car become heavy, the amount of labour and the work difficulty of conducting rod installed in increase in bus bar canister, reduce working effect.
