Description
Technical field
It the utility model is related to electric railway technical field, and in particular to a kind of electric railway sand cutting environment insulation
Son.
Background technology
With the gradual perfection of railway gauze and the needs of development of the West Regions, the Northwest's electric railway gradually starts to build
If.For railway electrification equipment along the outdoor arrangement of circuit, working environment is severe, by the Effect of Natural Disaster such as wind and snow, saline and alkaline, mist compared with
Greatly, particularly insulator.Lanzhou-Xinjiang high ferro and the Lan-xing Railway are by salt lake section, due to special geographical position and weather ring
Border, often there is strong wind sand and with the weather of sleet mist, will result in the large quantities of flashover tripping operations of insulator.2013 to 2016
Year, two lines there occurs insulator contamination accident, cause very big interference to normal operation, have a strong impact on the fortune of electric railway
Battalion's safety.
The content of the invention
The purpose of this utility model is to provide a kind of electric railway sand cutting environment insulator, overcomes and deposits in the prior art
The defects of.
Technical scheme is used by the utility model：
A kind of electric railway sand cutting environment insulator, it is characterised in that：
Including insulator body, upper metal cap and lower metal cap, upper metal cap and lower metal cap pass through adhesive and pad
It is separately fixed at the upper and lower end parts of insulator body；
Arranged for interval big full skirt and small full skirt in insulator body.
The umbrella disk of big full skirt and small full skirt is shaped as turing the fairshaped straight prismatic of length.
Creeping-increasing skirt is set in big full skirt in the middle part of insulator body.
Big full skirt and small full skirt surface attachment have PRTV coating materials.
Upper metal cap and lower metal cap end set chamfering, chamfering curvature are 7mm.
Upper metal cap outer end is connection end, is provided with bolt pin and U-shaped clip, passes through pressing plate, thin nut, packing ring, nut
Fastening installation.
The utility model has advantages below：
（1）The utility model full skirt size interval is distributed, and increases distance between two big full skirts, and increase gamp umbrella edge stretches out
Amount, prevents the connection of dunghill, improves the performance of antifouling work.
（2）Using the straight prismatic umbrella disk of fairshaped length, the wind and rain self-cleaning ability of insulator can be improved, reduces dust, salt
Deng aggregation of the dunghill on porcelain insulator umbrella disk surface.
（3）A piece of creeping-increasing skirt is bonded on insulator cluster parachute surface by viscose glue, creeping-increasing skirt is located in the middle part of insulator, Ke Yigai
Become the characteristic and planform on porcelain surface, improve pollution flashover voltage.
（4）Full skirt surface attachment PRTV coating, the mechanical performance of coating can reach the strong of the umbrella sheath material of insulator
Degree.
（6）Chamfered is carried out in upper metal cap and lower metal cap end, chamfering curvature is 7mm, can be effectively improved sharp
Metal corner angle electric field distortion.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1- pressing plates, 2- thin nuts, 3- nuts, 4- packing rings, 5- pads, 6- adhesives, the upper metal caps of 7-, 8- insulation
Sub- body, metal cap under 9-, 10-U shape clips, 11- bolt pins, 12- big full skirts, the small full skirts of 13-.
Embodiment
The utility model is described in detail with reference to embodiment.
A kind of electric railway sand cutting environment insulator that the utility model is related to, including insulator body 8, upper metal
Cap 7 and lower metal cap 9, upper metal cap 7 and lower metal cap 9 are separately fixed at insulator body 8 by adhesive 6 and pad 5
Upper and lower end parts.
Arranged for interval big full skirt 12 and small full skirt 13 in insulator body 8.Distance is to 20mm between increasing two big full skirts 12,
Increase the umbrella edge overhang of big full skirt 12 to 250mm, prevent the connection of dunghill, improve the performance of antifouling work.Big full skirt 12 and small
The umbrella disk of full skirt 13 is shaped as turing the straight prismatic of fairshaped length, can improve the wind and rain self-cleaning ability of insulator, reduces dust, salt
Deng aggregation of the dunghill on porcelain insulator umbrella disk surface.Creeping-increasing skirt is set in the big full skirt 12 at the middle part of insulator body 8, passed through
Viscose glue is on insulator cluster parachute surface, thus it is possible to vary the characteristic and planform on porcelain surface, improves pollution flashover voltage, pollution flashover voltage is relative
Raising amount can reach 60.3%, and have safe enough nargin.Big full skirt 12 and the surface attachment of small full skirt 13 have PRTV coating materials
Material, PRTV coating are that the high insulation supporting material of nanoscale is added on RTV coating bases, make it have very high mechanical strength
And adhesive force, the erosion of high wind sand weather is resistant to, meets requirement that overhaul of the equipments scrunches, can under filthy special serious conditions
Necessary water flushing or cleaning are carried out, the mechanical performance of coating is high.
Upper metal cap 7 and the end set chamfering of lower metal cap 9, chamfering curvature are 7mm.Conventional insulators metal cap seamed edge is
Right angle, according to Theory of Electromagnetic Field, sharp metal corner angle can cause electric field distortion.Carried out in upper metal cap 7 and the lower end of metal cap 9
Chamfered, chamfering curvature are 7mm, can be effectively improved sharp metal corner angle electric field distortion.The upper outer end of metal cap 7 is connection end,
Bolt pin 11 and U-shaped clip 10 are provided with, passes through pressing plate 1, thin nut 2, packing ring 4, the fastening installation of nut 3.
