Abstract
The utility model discloses a kind of locomotive Anti-fog lightning arrester, lightning arrester inside installs zinc oxide resistance sheet in epoxy resins insulation pipe, Base top contact wire bonding is at top wiring position and at its free end crimping binding post, bottom lightning arrester, circular flange is installed, flange is bolted on locomotive header, flange welds an earth connection with insulating outer layer, the end crimping binding post of earth connection, lightning arrester outside adopts silicon rubber to wrap up the exposed wire in all outsides and metal.The utility model is by adopting the mode of integrated outlet, silicon rubber is adopted to implement full parcel to lightning arrester outside, incident roof apparatus electric discharge flashover when effectively prevent the bad weather such as haze, ice and snow, decrease maintenance and set-up time, reduce maintenance cost, ensure that the safe operation of locomotive integral and the safety of contact line under bad weather.
Description
Technical field
The utility model relates to a kind of lightning arrester, particularly relates to a kind of locomotive Anti-fog lightning arrester, belongs to railway locomotive technical field.
Background technology
Essential electrical protection component on locomotive, the quality of its insulation quality directly affects the safe operation of locomotive integral and the safety of contact line.Locomotive lightning arrester is mounted on locomotive header, need work out of doors, and lightning arrester top lead position and lead-out wire and bottom mounting flange all in atmosphere exposed, if when there is the bad weathers such as haze, ice and snow and sand and dust in electrified sections, because the pollutant suspended in air often can cause the class of insulation between air to decline, easy generation power locomotive top equipment electric discharge flashover, contact line can be blown time serious, safely hidden danger is brought to locomotive operation, affects safety of railway traffic.Railway use section door by the cabling on cable rack position installing insulating sheath of lightning arrester, lead-out wire overcoat pyrocondensation insulating sleeve, be coated with insulating cement at mounting flange place, bottom, the nut at mounting flange place buckles insulator cap to strengthen protection to lightning arrester.When normal work, be arranged on lightning arrester top lead position on locomotive header and lead-out wire all with the high-tension electricity of 25kV, because Base top contact line is with bolts, need to overhaul this bolt when maintenance repair whether fastening, bolt looseness will produce electric discharge phenomena, thus causes the construction bolt position in sheath to generate heat and make insulating sleeve produce thawing.Also lead-out wire cover insulation heat-shrinkable T bush can be caused to melt if disconnected stock occurs Base top contact line.Bottom mounting flange needs when maintenance repair lightning arrester construction bolt to take off, and causes the increase of maintenance workload also to increase the impaired danger of sheath.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art, a kind of class of insulation that can improve locomotive lightning arrester is provided, avoid the generation of electrion accident, solve locomotive lightning arrester mist and dodge electric discharge problem, the locomotive Anti-fog lightning arrester of maintenance cost can be reduced.
The purpose of this utility model is achieved through the following technical solutions, this locomotive Anti-fog lightning arrester, lightning arrester inside installs zinc oxide resistance sheet in epoxy resins insulation pipe, Base top contact wire bonding crimps binding post in lightning arrester top post and at the free end of Base top contact line, bottom lightning arrester, circular flange is installed, circular flange is bolted on locomotive header, circular flange welds an earth connection, the earth terminal crimping binding post of earth connection, lightning arrester outside adopts silicone rubber insulation layer to wrap up the exposed wire in all outsides and metal.Lightning arrester adopts the mode of integrated outlet, and the overall silicone rubber insulation layer of lightning arrester adopts integral die process heat to be solidified into molded rubber parts.
The beneficial effects of the utility model, it is utility model locomotive Anti-fog lightning arrester, effectively can promote the class of insulation of lightning arrester cabling on cable rack position and lead-out wire and bottom mounting flange and other metal objects in inclement weather, effectively avoid the charged position of lightning arrester to installing circular flange and the electric discharge of other metalworks bottom it, decrease maintenance and set-up time, reduce maintenance cost, ensure that the safe operation of locomotive integral and the safety of contact line under bad weather.
Accompanying drawing explanation
Fig. 1 is the utility model locomotive Anti-fog lightning arrester structural representation.
In figure: 1-top post, 2-zinc oxide resistance sheet, 3-silicone rubber insulation layer, 4-circular flange, 5-earth connection, 6-Base top contact line.
Embodiment
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, carry out knowing to the technical solution of the utility model and intactly describe, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See accompanying drawing, the utility model locomotive Anti-fog lightning arrester is a brand-new lightning arrester, lightning arrester adopts the mode of integrated outlet, lightning arrester inside installs zinc oxide resistance sheet 2 in epoxy resins insulation pipe, Base top contact line 6 is welded on the free end crimping binding post of also Base top contact line 6 in lightning arrester top post 1, circular flange 4 is installed bottom lightning arrester, circular flange 4 is bolted on locomotive header, circular flange 4 welds an earth connection 5, the earth terminal crimping binding post of earth connection 5, lightning arrester outside adopts silicone rubber insulation layer 3 to wrap up the exposed wire in all outsides and metal.
The employing bulk silicon rubber insulation 3 mould pressing process thermosetting of lightning arrester changes into molded rubber parts, and lightning arrester core body is put into mould, injects silicon rubber, and lightning arrester outside adopts silicone rubber insulation layer 3 to wrap up the exposed wire in all outsides and metal.
The utility model locomotive Anti-fog lightning arrester, all adopt silicone rubber insulation layer 3 to wrap up exposed lightning arrester outlet point and Base top contact line 6 and bottom circular flange 4, earth connection 5 exactly, lightning arrester top post 1 adopts bolted and uses solder technology it to be linked into an integrated entity completely.At the free end crimping binding post of Base top contact line 6, and make the cluster parachute creepage distance of lightning arrester be not less than 1000mm, thus improve the class of insulation of the charged position of lightning arrester and its bottom circular flange 4 and other metal objects.At lightning arrester bottom circular flange 4 place, welding draws earth connection 5 with insulating outer layer, its earth terminal crimping binding post, can effectively avoid like this lightning arrester Base top contact line 6 to its circular flange 4 and other metal objects the electric discharge phenomena under the bad weather such as haze, ice and snow.Maintenance and set-up time effectively can be reduced after adopting this kind of lightning arrester.
