Description
technical field:
the utility model relates to the silica gel protected cover of a kind of 500kV insulator.
background technology:
500kV transmission line is located in field, wilderness, high mountain jungle mostly, these environment birds are numerous, and bird above line insulator string, hanging point cross-arm is nested, during defecation, surrounding electric field distorts, be easy to cause electric discharge flashover fault, and bird is when defecation, birds droppings can fall on the insulator and knot is solid at insulator surface, the insulator surface that accumulates over a long period can amass full birds droppings, birds droppings can form electrically conductive particles and be attached to insulator surface, greatly reduces the insulating effect of insulator, and electric discharge flashover fault very easily occurs.
replace season at the beginning of spring, the winter of entering changes in temperature, very easily occur sleet, rime, sleet, foggy weather, circuit suspension insulator is easy to accumulated snow and freezes, and forms rime, and especially synthetic insulator umbrella spacing is little, and accumulated snow is just more easily formed with freezing.Insulator string freezes or can run through the icicle of whole string after forming rime, every day is when the direct projection of the 10-14 o'clock sun, temperature gos up, or time more than zero centigrade, icicle starts to melt, the frozen water melted drops down under suspension insulator edge, Leakage Current increases severely, and forms continuous print frozen water conductive path, electric field distortion, cause the flashover voltage of insulator under power-frequency voltage significantly reduce thus under operating voltage, flashover occur, trip accident occurs.
in recent years, the filthy materials such as the dust of air and particulate get more and more, along with the flowing of air, the filthy material such as dust and particulate can be bonded at insulator surface with water molecules, accumulate over a long period, the dunghill of insulator surface can get more and more, in dry conditions, the resistance of filthy dust is very large, insulation property can not reduce, but under the condition that the air humiditys such as mist, dew, drizzle are large, the pollution layer of insulator surface will be moistening, greatly will increase in voltage effect lower surface conductance and Leakage Current, thus cause insulator to discharge along face pollution flashover.
one deck corrosion resistant coating can periodically be whitewashed in electric power line pole tower tower material surface, and corrosion resistant coating conduction.When whitewashing the cross-arm on insulator, be certain to inevitably drippage and there is the corrosion resistant coating of electric conductivity at insulator surface, and corrosion resistant coating can condense in insulator surface rapidly, is not easily eliminated.The corrosion resistant coating with electric conductivity can reduce the insulation property of line insulator greatly, and under the high pressure of 500kV, the possibility of circuit generation flashover fault can be very large.
summary of the invention:
the purpose of this utility model is to provide the silica gel protected cover of a kind of 500kV insulator.
above-mentioned object is realized by following technical scheme:
the silica gel protected cover of a kind of 500kV insulator; its composition comprises: silica gel full skirt A, silica gel full skirt B; described silica gel full skirt A and silica gel full skirt B joint have semicircle gap; described silica gel full skirt A and silica gel full skirt B has connection board respectively; the connection board of described silica gel full skirt A and silica gel full skirt B has screwed hole, and described silica gel full skirt A is corresponding with the screwed hole on the connection board of silica gel full skirt B.
the beneficial effects of the utility model:
1. the utility model can be mixed with bright-coloured redness, utilizes the sensitivity of bird to redness to fear and feature that the arc reflection sunray of device itself is strong, plays the effect of scaring birds, flock of birds dare not just be nested on the insulator.
anti-ice-flashing accident function: this device is arranged on directly over suspension insulator, accumulated snow is not icing can to protect 850-1000mm at sleet and snow ice weather, plays available protecting effect, thus avoid the formation of the whole string icicle of insulator to insulator string epimere 98%.It is through that insulator can not form the whole string of icicle, and icicle melts, and frozen water just can not form the bridge joint of insulator string, electric field distortion, and electric discharge trip accident is also avoided, and anti-ice-flashing object reaches, and proved is obvious.
heavy rain, foggy weather, because this device dish footpath is large, also make insulator creepage distance increase, and insulator string edge can not form continuous print electric discharge eaves gutter, reduce somewhat the occurrence probability of heavy rain, dense fog sudden strain of a muscle accident.
, antifouling work accident function: enough large in this device dish footpath itself, effectively can prevent corrosion resistant coating, the dunghill drippages such as birds droppings on the insulator, and be make with insulating material silica gel, the dust umbrella for insulator can be formed, there is special material on surface, there is good hydrophobicity performance, under the Nature rainwash and under the effect of wind-force, the self-cleaning ability on surface strengthens, not easily form concentrated discharge channel, thus there is higher anti-fouling flashover performance, the porcelain even reducing unknown cause can be reduced to a certain extent, glass, the flashover fault of composite organic insulator.
