Abstract
The utility model discloses an anti-flashing insulator with an integrated structure of climbing increasing skirt and parachute, consisting of a mandrel 1 and a fixed installation component 3 at one end of the mandrel 1. The utility model is mainly characterized in that the parachute skirt 2 on the mandrel 1 and the climbing increasing skirt 4 with a fixed installation component are constituted by polymer material; and that the climbing increasing skirt 4 and parachute skirt 2 constituted by polymer material extend towards both ends to completely cover the mandrel 1 and the fixed installation component 3 at the end. The utility model, without changing the basic measurements of present composite support pantograph and bus insulator, integrates organically the same insulating material of the climbing increasing skirt and the parachute skirt of the insulator, eliminating the original air gap and realizing gapless connection between the climbing increasing skirt and the parachute skirt with the withstood voltage of the joint surface is more than 25kv.
Description
Technical field:
The utility model relates to the power circuit high-tension insulator, particularly is the roof supporting insulator of use for electric locomotive.
Technical background:
The basic structure of insulator is to be provided with umbrella (sudden strain of a muscle) skirt that insulating material is made on plug, the effect of full skirt is arc, increases and climb and anti-pollution flashover, there is fixed installation part (flange) end of insulator, also is provided with an insulating barrier (being creeping-increasing skirt) on the fixed installation part (flange).But, therefore still there is air gap with the portion that combines (being equitant position between full skirt and creeping-increasing skirt) of umbrella (sudden strain of a muscle) skirt at creeping-increasing skirt because the height of insulator and the restriction that umbrella directly is subjected to technology and standard can not arbitrarily increase.Because the existence of air gap, make direct dry withstand voltage between this place and gold utensil less than 20KV, easily breakdown and form discharge, especially power circuit causes the full skirt of insulator to be coated with one deck dunghill with all using under pollution severity environment or bad weather condition in high-tension insulator and the use for electric locomotive roof supporting insulator.Dunghill forms electric pathway on the surface of insulator, flashover takes place, and pollution flashover voltage is difficult to be improved, and it is short to reveal distance along face, very easily cause the insulator full skirt that fixed installation part, mount pad and all edge discharges thereof, the particularly safe operation to electric locomotive are caused serious threat.
Summary of the invention:
The utility model discloses and a kind ofly can thoroughly eliminate the air gap that exists between upper and lower flange creeping-increasing skirt of insulator and full skirt, effectively improve the insulator electrical strength, further reduce the insulator probability of disruptive discharge over the ground, reach the creeping-increasing skirt of best anti-pollution flashover effect and the antifouling flash insulator of full skirt integral structure.
Realize that technical solution of the present utility model is as follows: comprise plug 1, the end of plug 1 is provided with fixed installation part 3, and key is that the creeping-increasing skirt 4 on full skirt 2 on the plug 1 and the end fixed installation part 3 is macromolecular material one formation; The fixed installation part 3 that creeping-increasing skirt 4 that described macromolecular material one constitutes and full skirt 2 extend plug 1 and end to two ends covers fully.
The macromolecular material of described one is at least more than one deck.
The surface coverage binding site of described fixed installation part 3 and plug 1 is shaped as the integral structure of cylinder or tetragonal body.
The utility model is on the basis of the basic size that does not change existing compound support pantograph, bus-bar insulator, combine adopting the same dielectric material to carry out organic one between the creeping-increasing skirt of insulator and full skirt, eliminated original air gap, realized seamless connection the between creeping-increasing skirt and full skirt, the junction outer surface to the gold utensil dry withstand voltage greater than 25KV.
Description of drawings:
Fig. 1 is an overall structure schematic diagram of the present utility model.
Embodiment:
See also Fig. 1, specific embodiment of the utility model is as follows: comprise plug 1, the end of plug 1 is provided with fixed installation part 3, key is that the creeping-increasing skirt 4 on full skirt 2 on the plug 1 and the end fixed installation part 3 constitutes for the macromolecular material one, and creeping-increasing skirt 4 that described macromolecular material one constitutes and full skirt 2 cover fully to the fixed installation part 3 of two ends extension with plug 1 and end; The one or both ends of plug 1 are provided with fixed installation part 3, fixed installation part 3 is a flange, plug 1 can be connected with locomotive or miscellaneous equipment by installed part 3, plug 1 surface is provided with the full skirt 2 that insulating material is made, full skirt 2 is used for arc, increases and climb and anti-pollution flashover, is the blocking-up insulator upper flange place of discharging over the ground, the most advanced and sophisticated point of shielding accumulation, be provided with the creeping-increasing skirt 4 that insulating material is made at fixed installation part 3 upper surfaces, creeping-increasing skirt 4 is an overall structure with full skirt 2.Full skirt 2 and creeping-increasing skirt 4 are all used with a kind of macromolecular material and are made, as are all composite materials such as silicon rubber or ethylene-propylene rubber, plastics, epoxy resin.The creeping-increasing skirt 4 and the full skirt 2 that are made of above-mentioned macromolecular material one cover fully to the fixed installation part 3 of two ends extension with plug 1 and end, make creeping-increasing skirt 4 and full skirt 2 with plug 1 and fixed installation part 3 closely knit integral coating, realize seamless connection the between creeping-increasing skirt and full skirt, make insulator full skirt (being the main body full skirt) and creeping-increasing skirt (on, the lower flange creeping-increasing skirt) forms a complete integral insulation structure with identical molecular structure, thoroughly eliminated the overlapped and air-gap that produces between the creeping-increasing skirt of existing insulator and full skirt joint portion, make direct dry withstand voltage between this place and gold utensil greater than 25KV, greatly promoted the electric property of insulator.
The macromolecular material of above-mentioned one is at least more than one deck; For making insulator further promote the electric property of insulator, the macromolecular material of above-mentioned one can be multilayer, promptly be covered with one deck earlier has and the strong macromolecular material of plug 1 associativity on the surface of plug 1, make itself and plug 1 strong bonded, can prevent to produce air gap because of a variety of causes causes macromolecular material and 1 of plug in actual use, and then be covered with at least one floor height molecular material at this floor height molecular material, make itself and first floor macromolecular material strong bonded, form sandwich construction, insulator full skirt and creeping-increasing skirt use the insulating material of same nature, form the integrated binding of same molecular structure, possessed identical electric property and mechanical performance simultaneously; Or every floor height molecular material can use different macromolecular materials as required, gives full play to the high voltage performance that used different macromolecular materials self possess separately, further improves the insulator electric property, reaches best anti-pollution flashover effect; The generation type of above-mentioned insulating barrier can be to form by different technical process (containing process form repetition, identical).
The above-mentioned fixed installation part 3 and the surface coverage binding site of plug 1 are shaped as the integral structure of cylinder or tetragonal body; The assembly that the integrated joint portion profile that coats of insulator full skirt and creeping-increasing skirt can be cylinder or tetragonal body or cylinder and tetragonal body also can be mounted in the space that the metal polygon device on the insulator forms, to be adapted to all kinds of high-tension apparatuses.
