Abstract
The utility model relates to a kind of silicon rubber insulator that is provided with shed skeleton, is made up of insulation mandrel 1, full skirt 2, base 3 and top nested 4.Be provided with the shed skeleton 2-1 that radius length does not wait in a week of its insulation mandrel, be coated with silastic-layer 2-2 at the outer surface of shed skeleton and insulation mandrel, described insulation mandrel, full skirt, base and top are nested to be bonded as one by compacting.This insulator is mainly used in the electric locomotive of electrified main line, and mine mining etc. of modernization is industrial.It is good to possess existing hydrophobicity, outside the good advantage of the insulating properties of electrocorrosion-resisting, material and ageing resistace; It is many also to have full skirt sheet number, and the skirt chip size is big, diameter of mandrel is little, and big or small full skirt ratio is big, has increased creepage distance and solid firm, good integrity widely, and mechanical strength is much higher than like product, advantages such as long service life.
Description
Technical field
The utility model belongs to the power industry technologies field, specifically a kind of silicon rubber insulator that is provided with shed skeleton, and it is mainly used in the electric locomotive of electrified main line, and mine mining etc. of modernization is industrial.
Technical background
Fast development along with my Chinese Railway electric railway, main line is realized electrified substantially, the railroad traction of electrified main line leans on high-tension electricity as power resources, electric power is got involved in the process of locomotive, necessary electrification motorcycle pantograph supporting insulator, each electric locomotive head is equipped with tens such insulators.The original pantograph supporting insulator that uses of China is full porcelain insulator, this insulator is because the dirty flashover voltage level of resistant is low, and hydrophobicity is poor, under the inexorable trend that train constantly raises speed, the weakness of himself, the safe operation to train causes serious threat.Use the silicon rubber insulation porcelain insulator in the electric locomotive abroad for a long time, it can address the above problem, yet because block of bow collector of electric locomotive supports that the technical difficulty of silicon rubber insulator is bigger, so make slow progress, also there is such or such problem: for example, because the silastic material self character determined, make that the full skirt skirt sheet of simple silicon rubber insulator can not make excessive, quantity is too much, cross conference in storm because self intensity difference easy fracture or bending; Too much the skirt sheet easily is in contact with one another and causes the full skirt bridge joint to cause flashover; So, because the skirt sheet is not only few but also little, make creepage distance little, the electric easy puncture in interface is so insulating reliability is poor.
Summary of the invention
The purpose of this utility model is in order to overcome defective of the prior art, provides that a kind of full skirt intensity is good, the better silicon rubber insulator of bulk strength, has increased creepage distance effectively, has improved insulating reliability widely.
This purpose realizes with following technical proposal: be provided with the silicon rubber insulator of shed skeleton, it is formed by insulation mandrel, full skirt, base and top are nested.Week at its insulation mandrel is provided with the shed skeleton that radius length does not wait, and is coated with silastic-layer at the outer surface of shed skeleton and insulation mandrel.Described insulation mandrel, full skirt, base and top are nested to be to be bonded as one by compacting.
The utility model is compared with the prior art: except the hydrophobicity that possesses prior art is good, outside the advantage such as the insulating properties of electrocorrosion-resisting, material and ageing resistace are good; It also has self characteristics, for example same insulator highly, product of the present utility model can increase full skirt sheet number, strengthens the skirt chip size, dwindles diameter of mandrel, makes plug firm, size full skirt ratio is big, thereby increased creepage distance widely, helped resistant and dodge, be commonly called as and climb middle insulator greatly, its insulating reliability can be three to five times of prior art, prevents pollution flashover accident effectively.In addition, it makes its solid more firm, good integrity through the type of attachment that disposable notes are pressed, hot pressing becomes one, and its mechanical strength is much higher than like product, so it has in light weight, the characteristics of withstand voltage, folding, impact-resistant characteristic, long service life.
Description of drawings
Fig. 1 is the utility model overall structure cutaway view.
Embodiment
In conjunction with the accompanying drawings overall structure of the present utility model is constituted and is described specifically:
As shown in Figure 1, described silicon rubber insulator, form by insulation mandrel 1, full skirt 2, base 3 and top nested 4, be provided with the shed skeleton 2-1 that radius length does not wait in a week of its insulation mandrel, outer surface at shed skeleton and insulation mandrel is coated with silastic-layer 2-2, and described insulation mandrel, full skirt, base and top are nested to be to be bonded as one by compacting.
Manufacturing process of the present utility model: according to the profile and the size of insulator, at first carry out mold design, plug and shed skeleton are to adopt high strength, anti-measuring body glassfiber insulation resin material compacting, they are nested with metal material base, top, press through annotating in mould, hot pressing becomes one.The formed body that suppresses is put into another mould carry out the silicon rubber coating, with solid state si rubber through the fusing, silicon rubber after the fusing injects in the mould, makes it to be penetrated into equably all sites strong bond parcel of skeleton under the effect of pressure, and in suitable temperature and time curing molding.
