Abstract
The utility model relates to a bar-shaped suspension type ground wire insulator. The utility model is provided with an insulating element 1, electric-conducting elements 2 and 3 which are fixed on the insulating element 1, and an upper electrode 4 and a lower electrode 5 which are connected with the electric-conducting elements 2 and 3. The insulating element 1 is a solid bar body, and an inner breakdown distance of insulating element 1 is corresponding to the and an outer flashover distance of the insulating element 1; thus, the breakdown phenomenon can not be generated. The utility model is not provided with an inner glue mounting structure, so the service life of the utility model is long. A gap protecting distance can be regulated before the utility model is used, so the gap distance can be easily and accurately controlled. Porcelain sand is glued at both ends of the insulating element, so the firm effect between the insulating element and an iron cap can be ensured, the stability of the gap protecting distance is assured, and the high reliability is realized.
Description
The utility model relates to a kind of ground wire insulator, especially a kind of rod insulator ground wire insulator.
The ground wire insulator is by insulating part, is fixed on the electric-conductor on the insulating part and the upper/lower electrode that links to each other with electric-conductor is constituted, and disc suspension ground wire insulator is traditional a kind of in the ground wire insulator.The insulating part that plays insulating effect in the disc suspension ground wire insulator is a porcelain spare, porcelain spare is processed to the porcelain head of hollow and the full skirt of dish type usually, electric-conductor is chapeau de fer and steel pin, the chapeau de fer mucilage binding is in the outside of hollow porcelain head, steel pin mucilage binding is at the interior eye of hollow porcelain head, upper and lower electrode then is connected on chapeau de fer and the steel pin, and the thickness of this hollow porcelain head only is part to tens/one of dry arc-over distance, and punch-through takes place easily.In addition, because the steel pin is to locate at the interior eye of hollow porcelain head with the adhesive mucilage binding, if adhesive raises with temperature swelling has taken place, then the porcelain head of hollow is difficult to bear, and can crack; Otherwise; contraction occurred if adhesive reduces with temperature, then the steel pin just might become flexible, rotate, and loosening, the rotation of steel pin will cause being fixed on the change in location of the bottom electrode on the steel pin; and then changed the protection clearance distance, will directly influence the protective value of whole ground wire insulator like this.
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and the reliable rod insulator ground wire of a kind of insulation property insulator is provided.
The utility model above-mentioned purpose realizes by following these means of skill.A kind of rod insulator ground wire insulator is provided with insulating part 1, is fixed on electric-conductor 2,3 on the insulating part 1 and top electrode 4, the bottom electrode 5 that links to each other with electric-conductor 2,3, and insulating part 1 is solid barred body.
Electric-conductor 2,3 is the chapeau de fer that is fixed on insulator [1] termination.
Insulating part 1 two ends are stained with porcelain sand, and the chapeau de fer mucilage binding is on termination, insulating part 1 two ends.
The insulating part of rod insulator ground wire insulator provided by the utility model is solid porcelain rod, and striking distance is suitable with outer flashover distance in it, punch-through can not take place, and does not have interior mucilage binding structure, long service life.Upper and lower electrode uses the bolt lock ring respectively on the chapeau de fer of top and bottom; enough fastening forces are arranged; clearance distance can be in the preceding adjustment of reaching the standard grade; be easy to accurate control gap distance; and the sticking porcelain sand in insulating part two ends; guaranteed between insulating part and chapeau de fer firmly, make the protection clearance distance stable, the reliability height.
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model example structure schematic diagram.
Fig. 3 is the vertical view of the utility model example structure.
Below in conjunction with drawings and Examples the utility model is further described.As Fig. 1, Fig. 2, shown in Figure 3: the utility model embodiment is equipped with insulating part 1 with existing disc suspension ground wire insulator, is fixed on electric-conductor 2,3 on the insulating part 1 and top electrode 4, the bottom electrode 5 that links to each other with electric-conductor 2,3, the insulating part 1 that different is among the utility model embodiment is solid porcelain rod, the two ends of solid porcelain rod is stained with porcelain sand, electric-conductor 2,3 is chapeau de fer, mucilage binding is on the termination of solid porcelain rod, one end of top electrode 4, bottom electrode 5 is a buckle-like, each with two bolt lock rings on upper and lower chapeau de fer.The protection gap is stable, and the reliability height can not produce punch-through.
