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, research for composite post insulator DC Flashover Characteristics is less, Flashover Characteristics preferably composite post insulator parameter can not be provided, for this reason, how design is optimized to overcome above-mentioned defect to the full skirt 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 suspension insulator, provides a kind of and can prevent that dirt from spilling, the composite insulator of reinforced insulation performance.
For reaching above-mentioned purpose, the utility model proposes in the anti-lightning of a kind of contact nets in electrified railways, cast anchor composite 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 full skirt comprises multiple insulation gamp, comprise umbrella in one or more insulation between adjacent two insulation gamps, comprise one or more insulation umbellule between umbrella in adjacent insulation gamp and insulation, the spacing wherein between adjacent two insulation gamps are greater than 60mm.
According to the composite insulator that the utility model proposes, the diameter of wherein said insulation gamp is 140mm, and in described insulation, the diameter of umbrella is 110mm, and the diameter of described insulation umbellule is 80mm.
According to the composite insulator that the utility model proposes, wherein said insulation full skirt comprises umbrella and 10 insulation umbellules in 5 insulation gamps, 5 insulation altogether.
According to the composite insulator that the utility model proposes, wherein said connection gold utensil comprises link and lower link, and described upper link and described lower link have identical structure.
According to the composite insulator that the utility model proposes, wherein said connection gold utensil comprises link and lower link, and described upper link and described lower link have different structures.
According to the composite insulator that the utility model proposes, the form of wherein said upper link is any one in ball-and-socket gold utensil, ears gold utensil, bulb gold utensil or monaural gold utensil.
According to the composite insulator that the utility model proposes, the form of wherein said lower link is any one in ears gold utensil, bulb gold utensil or monaural gold utensil.
Compared with prior art, the utility model has the following advantages:
1) the utility model has carried out design optimization on original beveled structure basis, makes beveled structure become large, medium and small 5 beveled structures;
2) after design optimization, the distance between gamp strengthens, and insulator creepage distance also strengthens simultaneously, thus improves the thunder-lightning flashover of composite insulator, the ability of pollution flashover; Umbrella spacing extends arc channel after strengthening, and the ice efficiently solving insulator dodges, rain dodges problem;
3) insulator high-pressure side full skirt of the present utility model diminishes gradually, contributes to the arc-distribution of balanced insulator high-pressure side, thus improves the thunder-lightning flashover of composite insulator;
4) composite insulator of the present utility model is electric railway and high-speed railway specific complex insulator.
