Abstract
The invention discloses a large-tonnage disc-shaped suspension type glass insulator, comprising an iron cap, a glass piece and a steel pin, wherein the iron cap is arranged at the upper end of the glass piece through a cement adhesive in an adhered manner; the steel pin is arranged in an inner diameter of the glass piece through the cement adhesive in the adhered manner; the iron cap is internally provided with an inner hole matched with the steel pin in size; a locking pin is arranged at the bottom of the inner hole; the head part of the glass piece is cylindrical and the lower end of the glass piece is of a high-low staggered umbrella skirt structure; the outer diameter of the glass piece is 400mm and the diameter of the head part of the glass piece is 120mm; the height of the head part of the glass piece is 120mm and the diameter of the steel pin is 33mm. The head part of the glass piece is designed to be the cylindrical and high-low staggered umbrella skirt structure and the size of the glass insulator is reasonably matched, so that the strength grade of a product can reach 76 tons and parallel-connection string number in the actual use can be reduced; and therefore, the materials and the space for constructing an ultrahigh-voltage power transmission line are greatly saved and the safety performance is greatly improved.
Description
Technical field
The present invention relates to a kind of glass insulator, relate in particular to a kind of large-tonnage disc suspension glass insulator.
Background technology
Cap and pin insulator is the most most important a kind of line insulator of a kind of use.According to existing domestic and international standard code; Its specified machinery () tensile failure load value is as the foundation of dividing this product; Existing product strength grade has: 9 grades such as 4 tons, 7 tons, 10 tons, 12 tons, 16 tons, 21 tons, 30 tons, 40 tons, 53 tons, insulator adopts two strings or many string structures pattern to satisfy the needs of varying strength during use.But do not surpass 53 tons insulator in the prior art, and in the extra-high voltage electric power conveying circuit is built, if can improve the product strength grade then can reduce parallel connection string number, not only economical with materials and space greatly, its coefficient of safety also significantly improves.
Summary of the invention
To above-mentioned technological deficiency, the present invention proposes a kind of large-tonnage disc suspension glass insulator.
In order to solve the problems of the technologies described above, technical scheme of the present invention is following;
A kind of large-tonnage disc suspension glass insulator comprises chapeau de fer, glass workpiece and steel pin, and said chapeau de fer is located at the upper end of said glass workpiece through the cement glue mucilage binding; Said steel pin is located in the internal diameter of said glass workpiece through the cement glue mucilage binding; Be provided with the endoporus that cooperates with steel pin size in the said chapeau de fer; Said endoporus bottom is provided with locking pin; Said glass workpiece head is cylindrical, and the lower end is the umbrella skirt construction that height interlaces, and the overall diameter of said glass workpiece is 400mm, and said glass workpiece head diameter is 120mm, and said glass workpiece height of head is 120mm, and said steel pin diameter is 33mm.
A kind of large-tonnage disc suspension glass insulation substring, glass insulator is located at the steel pin of another glass insulator through the inner hole sleeve of chapeau de fer and is locked through said locking pin.
Further, above-mentioned locking pin is " R " type.
Beneficial effect of the present invention is: through the umbrella skirt construction glass workpiece head design is cylindrical and that height interlaces; And through rational Match to size of the present invention; Make the product strength grade can reach 76 tons; Can reduce parallel connection string number in actual use, make the extra-high voltage electric power conveying circuit build economical with materials and space greatly, security performance also significantly improves.
Description of drawings
Fig. 1 is a perspective view of the present invention.
Embodiment
To combine accompanying drawing and specific embodiment that the present invention is done further explanation below.
The mechanical strength of glass insulator has confidential relation with the size of its textural association and accessory, and its mechanical strength of various structure is different, even structure is identical, but each accessory size is different, and its mechanical strength also alters a great deal.Adopt the glass workpiece 5 column type heads and the umbrella rib structure combining that just interlaces among the present invention; Have good mechanical properties and electric property; Then through improving the selected of chapeau de fer 2 and steel pin 3 load-carrying surface form parameters; Convert glass workpiece when making product bear tensile load substantially to and bear even compression, effectively raise mechanical failure load.Further, the present invention provides the disc suspension glass insulator of a kind of mechanical strength up to 76 tonnes, and this glass insulator is made up of chapeau de fer 2, glass workpiece 5 and steel pin 3 three big major parts.Belong to socket cap and the staggered umbrella skirt construction of height by head and umbrella shape type 6 shapes, mucilage binding structure in belonging to by the mucilage binding pattern, this structure is can puncture type type B insulator.Chapeau de fer 2 is glued at glass workpiece 5 tops through cement glue 4, and chapeau de fer 2 is provided with endoporus 7, and this endoporus 7 can be connected on the electric power pylon through gold utensil; 3 on steel pin is glued at glass workpiece 5 internal diameters through cement glue 4, can connect and fixing output lead through gold utensil, and insulator is to connect bunchiness (the ball-and-socket socket of the bulb of steel pin 3 and chapeau de fer 2) according to electric pressure; So the monolithic insulator is called the string element; All connecting portions all adopt 1 locking of " R " type locking pin, and the characteristics of " R " locking pin 1 are that locking is safe and reliable, and dismounting is convenient; The insulator string element has maximum twisting space, avoids the disappearance of losing insulator because of the jam of locking.Chapeau de fer 2, steel pin 3 adopt the high strength cement adhesive glued with the adhesive of glass workpiece 5, make it to become rigid body.76 tonnes of its intensity of disc suspension glass insulator is about 1.5 times of existing highest ranking.Critical component is an insulating glass spare 5, and the diameter of glass workpiece 5 reaches 400mm (disk track), head diameter 120mm, height of head 120mm, weight 13kg, steel pin 3 diameter 33mm.Glass workpiece 5 of the present invention can adopt common soda-lime-silica glass, uses compression moulding, and steel pin 3 can adopt No. 65 manganese steel of diameter 33mm.Steel cap 2 can adopt magnesium iron, and adhesive uses Portland cement, and mixing 6# sand is aggregate.76 tonnes of insulators of the present invention have improved insulator greatly and have carried the lead ability.Such as replace 53 tonnes of insulators of 3 strings with 2 strings, can reduce parallel connection string number, make the extra-high voltage electric power conveying circuit build economical with materials and space greatly.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the present invention's design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the protection range of the present invention.
