Description
Technical field
The utility model relates to transmission line technical field, particularly a kind ofly can prevent dirt from spilling, improve mechanical strength, the composite insulator of reinforced insulation performance.
Background technology
Composite insulator is a kind of special insulation control, can play an important role in overhead transmission line.In one's early years, insulator is used for electric pole, and slowly develop and hung the insulator of a lot of plate-like in one end of high type high-tension bus-bar connection tower, it is made up of glass or pottery usually in order to increase creepage distance, is just insulator.Insulator plays two basic roles in overhead transmission line, namely support wire and prevent electric current return ground, these two effects must be guaranteed, insulator should not to change the various dynamo-electric stress that causes and losing efficacy due to environment and electric loading condition, otherwise insulator would not produce great effect, use and the service life of whole piece circuit will be damaged.
When traditional composite insulator is applied to high aerial; usually can be subject to the erosion of sleet; or the excremental pollution of flying bird; As time goes on; if can not be cleared up in time and be protected; this erosion or pollution can be more and more serious, probably cause composite insulator to lose efficacy, produce the serious consequence being difficult to expect.Up to the present, under different umbrella skirt construction Parameter Conditions, the research for composite post insulator DC Flashover Characteristics is less, can not provide Flashover Characteristics preferably composite post insulator parameter.Also there is significant limitation in existing composite insulator in addition in mechanical strength, and such as the insulator holding capacity of ceramic core rod is little at present, and applicable object is very narrow, can only be applied in the special occasions not bearing or only bear very little pulling force.For this reason, how design is optimized to overcome above-mentioned defect to the structure of suspension type composite post insulator, becomes those skilled in the art's problem demanding prompt solution.
Summary of the invention
The purpose of this utility model overcomes the potential safety hazard existed in existing composite insulator, provides a kind of and can prevent that dirt from spilling, reinforced insulation performance, improves the composite insulator of mechanical strength.
For reaching above-mentioned purpose, the utility model proposes a kind of electric railway contact porcelain composite rod insulator, comprise insulation mandrel, insulation full skirt and be connected gold utensil, described insulation mandrel is played a supporting role to composite insulator, for realizing interior insulation function, and bear mechanical load; It is outer that described insulation full skirt is arranged on described insulation mandrel, for realizing external insulation function; Described connection gold utensil is the metal termination at composite insulator two ends, for realizing the connection of composite insulator and other electric equipment; Wherein, described insulation mandrel is solid ceramic rod; Described insulation full skirt is silastic structure, comprises multiple insulation gamp and multiple insulation umbellule and the both ends of described insulation full skirt are insulation gamp, is provided with multiple insulation umbellule between adjacent two insulation gamps.
According to the composite insulator that the utility model proposes, wherein, 7 insulation gamps and 12 insulation umbellules are comprised in described insulation full skirt altogether.
According to the composite insulator that the utility model proposes, wherein, the diameter of described insulation gamp is 210mm, and the diameter of described insulation umbellule is 180mm; Or the diameter of described insulation gamp is 220mm, the diameter of described insulation umbellule is 190mm.
According to the composite insulator that the utility model proposes, wherein, described connection gold utensil comprises the pressing plate gold utensil of one end and the monaural gold utensil of the other end.
Compared with prior art, the utility model has the following advantages:
1) the utility model adopts solid porcelain rod as insulation mandrel, and exterior insulation adopts silicon rubber umbrella skirt structure, is pioneering in electrification railway contact net insulator;
2) beveled structure adopts aerodynamic principle, adopts large umbellule structure, and full skirt design increases the duty ratio of umbrella shape, improves effective creepage distance utilance, also can reduce full skirt surface contamination amount in operation, thus improve the antifouling work ability of product;
3) compared with traditional porcelain insulator, umbrella spacing of the present utility model, creepage distance increases all greatly, thus makes the improvement Flashover Characteristics of insulator, significantly improves the pollution flashover voltage of insulator.
4) compared with traditional composite insulator, mechanical strength improves greatly, ensure that the safe operation of contact line circuit.
5) porcelain core composite insulator of the present utility model is electric railway and high-speed railway special isolation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the electric railway contact porcelain composite rod insulator of the utility model first embodiment;
Description of reference numerals: 10-insulate full skirt; The upper link of 20-; Link under 30-; 40-insulation mandrel; 101-insulate gamp; 102-insulate umbellule.
Embodiment
Below in conjunction with accompanying drawing, with regard to above-mentioned being described further with other technical characteristic and advantage of the utility model.
Referring to Fig. 1, is the structural representation of the electric railway contact porcelain composite rod insulator of the utility model first embodiment.As shown in Figure 1, composite insulator centre in the present embodiment is an insulation mandrel be made up of solid ceramic 40, compared with traditional glass fibre plug, ceramic core rod of the present utility model has better mechanical strength, is conducive to the safe operation ensureing contact line circuit; The periphery of insulation mandrel 40 is provided with silicone insulation full skirt 10, the full skirt 10 that wherein insulate comprises according to aerodynamic principle the insulation gamp 101 that 7 diameters are 210mm, comprise the insulation umbellule 102 that two diameters are 180mm between adjacent two insulation gamps 101, the length of whole insulation full skirt 10 is approximately 520mm.According to different application scenarios, above-mentioned size can suitably change, and the diameter as the gamp 101 that insulate is set to 220mm, and the diameter of insulation umbellule 102 is set to 190mm.Full skirt design of the present utility model increases the duty ratio of umbrella shape, improves effective creepage distance utilance, thus can reduce the contamination amount on full skirt surface in running, improves the antifouling work ability of product.
Link 20 and 30 is respectively used to be connected other electric equipments.According to different connection requests, upper link 20 and lower link 30 can have different forms.Shown in Fig. 1 is a kind of comparatively conventional form, and namely one end is pressing plate gold utensil, and the other end is monaural gold utensil.Other common connected mode also can be set in addition according to actual needs, repeat no longer one by one herein.
