Abstract
The utility model discloses an anti-pollution flashover ascent skit insulator with super safety performance, which comprises a cored bar and au umbrella skirt. One end of the cored bar is provided with a rigid mount member, the side surface of which is provided with an insulating material layer connected with the umbrella skirt. The structure of the utility model is quite simple in that the insulating material layer (or anti-pollution flashover ascent skit) must be formed an integral insulating layer with a certain degree of cohesion with the umbrella skirt, which can increase the insulation of the surface electricity creeping and downsize the current leakage. The point where the piezoelectric charge centers is completely covered, therefore the high tension electricity of centered piezoelectric charge will not puncture the insulating layer, thereby downsizing the occurrence ratio of insulator flashover accident and enhancing the safety of the insulator.
Description
Technical field:
The utility model relates to the electric fittings of use for electric locomotive, specifically is meant the locomotive insulator that uses under the high pressure.
Technical background:
Electric locomotive operates in different atmospheric environments and weather conditions, insulator on its roof is subjected to various pollutions, seriously regional as filth, mist vapour, icing, accumulated snow, light rain, dust and greasy dirt etc., insulator generally is the top that is fixed on locomotive, the basic structure of insulator is to be provided with the full skirt that insulating material is made on plug, its upper end is a fixed installation part, the effect of full skirt is an arc, increase and climb and anti-pollution flashover, but because the height of insulator and the restriction that umbrella directly is subjected to technology and standard, can not arbitrarily increase, still have and to discharge between umbrella edge and the fixed installation part, full skirt lining one deck dunghill of particularly working as insulator, dunghill forms electric pathway on the surface of insulator, and the insulation property of insulator are greatly reduced, and flashover takes place, pollution flashover voltage is difficult to be improved, it is short to reveal distance along face, very easily causes the insulator full skirt to the fixed installation part, mount pad and all edge discharges thereof cause serious threat for the safe operation of locomotive.
Summary of the invention:
Goal of the invention of the present utility model is to disclose a kind of insulator with good electrical security performance.
Realize that technical solution of the present utility model is as follows: comprise plug 4 and full skirt 3, plug 4 one ends have fixed installation part 1, and key is that fixed installation part 1 side surface is provided with an insulation material layer 2, and insulation material layer 2 is connected with full skirt 3.
Described fixed installation part 1 is a flange.
Described fixed installation part 1 is one to have the cylindrical body of negative thread.
Described insulation material layer 2 is connected with full skirt 3 one.
Described insulation material layer 2 has an end face extending level section 5 to fixed installation part 1.
Described insulation material layer 2 can be silicon rubber or plastics or epoxy resin or polytetrafluoroethylene.
The utility model structure is very simple, described insulation material layer can directly be enclosed within on the insulator top fixed installation part or through whole sulfuration and make itself and fixed installation part form the insulating barrier with certain adhesive strength, above-mentioned insulation material layer (can be described as dirt-proof flashing increase and climb skirt) must and the full skirt of insulator between form an all-in-one-piece insulation top layer mutually, then greatly increasing surface creepage isolates, reduce leakage current, and the tip that high voltage electricity is concentrated is all covered, the high-tension electricity that produces because of accumulation can not puncture insulating barrier, thereby reduce the probability of happening of insulator arc-over fault, finally improved the electrical safety performance of insulator.
Description of drawings:
Fig. 1 is the structural representation of an embodiment of the present utility model.
Fig. 2 is the structural representation of another embodiment of the present utility model.
Embodiment:
See also Fig. 1~Fig. 2, specific embodiment of the utility model is as follows: comprise plug 4 and full skirt 3 (also claiming to dodge skirt), plug 4 one ends have fixed installation part 1, insulator can be connected with locomotive or electric equipment by fixed installation part 1, full skirt 3 can play arc, increase and climb and the effect of anti-pollution flashover, key is that fixed installation part 1 side surface is provided with an insulation material layer 2, and insulation material layer 2 is connected with full skirt 3; Because the existence of insulation material layer 2, in the basic size that does not change existing compound support pantograph, bus-bar insulator, the gold utensil that insulator top can be leaked outside coats, improved the whole creepage distance of insulator, insulation subbase creep distance behind the coated insulation material layer 2 increases by 45~60mm, and total length will be above 1200mm.
Described fixed installation part 1 is a flange, is connected with locomotive or electric equipment by flange.
Described fixed installation part 1 is one to have the cylindrical body of negative thread, is connected with locomotive or electric equipment by negative thread, and different fixed installation parts 1 can make things convenient for the I﹠M of actual use.
Described insulation material layer 2 is connected with full skirt 3 one; It can be produce once one-body molded, but also insulation material layer 2 is made with full skirt 3 gradation, but the two must cover insulator surface fully, to improve insulation effect.
Described insulation material layer 2 has an end face extending level section 5 to fixed installation part 1; The existence of this horizontal segment 5 can further improve insulation effect, and insulation material layer 2 is an elastic material simultaneously, when fixed installation part 1 is installed with locomotive or electric equipment, the slit can be filled with fully, and insulation effect is better.
Described insulation material layer 2 can be silicon rubber or plastics or epoxy resin or polytetrafluoroethylene.
