Description
Technical field
The invention belongs to the high-speed electric railway equipment technical field, relate in particular to the special-purpose section insulator of a kind of electrification railway contact net.
Background technology
At present, there is the hard spot phenomenon in several special-purpose section insulator majorities of high speed railway electrified contacting nets always, it is relatively poor that the low and complicated parts of integral body mechanical stretching load intensity need connection at the scene easily to get loose stability, the scene required accessory appliances of installation and accessory are many, and the insulating power that have are hanged down and caused the generation that slide plate discharges, interior breakdown fault appears in insulator of insulating.The dropper line is subject to shackle deadweight influence distortion sometimes, can make shackle meeting inclined impact pantograph after the distortion, in that being installed, shackle device place do not have elasticity, because the shackle deadweight can form big hard spot, when motorcycle pantograph slided into the shackle below, the hard spot situation that the shackle deadweight forms forced pantograph pan and shackle slideway to increase the weight of hard grind and decreases, influence the pantograph-catenary current collection quality and cause pantograph and catenary fault easily, damage motorcycle pantograph and cause a serious accident.
Summary of the invention
The defective of comprehensive above-mentioned present shackle, the present invention is according to raising and the demand of present high ferro technical requirements, designs a kind of section insulator and is difficult for producing the ship type section insulator that discharge, good insulation preformance, overall mechanical strength height, installation place do not have hard spot.This ship type section insulator includes: composite insulator, quick fixation structure termination, high-strength aluminium deadhead, insulating support, insulation slideway, extinguishing arc conduction slideway, extinguishing arc piece, balance bracket and connecting clamp.It is characterized in that: this ship type section insulator adopts single composite insulator to be connected with the crimping of quick fixation structure termination, and the quick fixation structure termination is inlaid in the high-strength aluminium deadhead and uses bolt.Three insulating supports are separately fixed on the composite insulator, two insulation slideways are separately fixed on three insulating supports, four arcing ring conduction slideways are installed in the high-strength aluminium deadhead outside at two ends respectively, form the whole skeleton of firm shackle, on the arcing ring conduction slideway extinguishing arc piece is set, two balance brackets are installed in respectively on the high-strength aluminium deadhead uses bolt, and integral body is ship type shape.The tail end of said extinguishing arc conduction slideway is provided with C type arcing ring, and C type arcing ring has rapid arc extinction, shortens discharge time, has protection insulation slide plate, insulator effect.
The present invention is simple in structure in light weight, easy for installation non-maintaining; The high unit design sound construction of integral structure mechanical load intensity; Integral structure good insulation preformance, creep distance and air insulation distance are big.C type arcing ring has quick elimination arcing, electric discharge phenomena; More possess good antifouling property, use in the contact system place that is fit to the heavy pollution environment; Single unit system can keep balance, good springiness automatically, mainly eliminates the hard spot that the shackle own wt causes, and can make shackle place and bow net keep elasticity consistent, ensures that the locomotive high-speed secure is current.
