Abstract
The utility model discloses a composite suspension insulator with increase in an iron cap capped silicone rubber umbrella skirt. The composite suspension insulator with the increase in the iron cap capped silicone rubber umbrella skirt possesses an iron cap and a steel pin which are fixedly connected as one via a cement adhesive on the inner and outer walls of the insulator, at least one iron cap boss is arranged on the iron cap, and the outer surfaces of the iron cap, the steel pin and an insulator possess the silicone rubber umbrella skirts. The composite suspension insulator with the increase in the iron cap capped silicone rubber umbrella skirt is characterized in that the silicone rubber umbrella skirt at the outer wall of the iron cap is extended to the position of the boss of the iron cap. The advantages of the utility model are that the thicknesses of the roots of the silicone rubber umbrella skirt group and the accommodation range to the outer surface of the iron cap are increased, so that the whole composite suspension insulator enables the number of the umbrella fins to be increased but barely increasing the weight under the premise of reducing the diameters of the silicone rubber umbrella fins, can satisfy the demands for high-voltage long-distance power transmission and transformation on any condition, and enables the diameters of the umbrellas and the damaged rate caused by suffering lightning stroke or overvoltage impact during use to be reduced, the number of the umbrellas and a creep distance to be increased, the breakdown resistance and steep wave impact resistance of a product and the service life and use performance of the product to be enhanced.
Description
Technical field
The utility model belongs to the dish-type composite insulator using in power circuit, and definite saying is a kind of composite suspension type insulators that increases chapeau de fer coated Si rubber full skirt.
Background technology
For the compound dish-type insulator of current use, the structure of its inner core is continued to use the basic structure of original porcelain or nature of glass dish-type insulator always, at the umbrella wing of the additional one deck silicon rubber of its outer surface, (the umbrella wing is called again full skirt) is although solved a lot of problems, such as anti-pollution flashover, durable, reduce circuit cleaning time and number of times etc., obtained applying greatly.But, because being has continued to use original dish configuration, just cause the inevitable problem existing in a manufacture and actual use, that is: because the axial dimension of the dish-type insulator of original structure is partially short, umbrella wing quantity only has 1 to 2, reach at most reluctantly 3, under the mal-condition in strict experiment condition and the practical application such as steep wave, creepage experiment, very easily lost efficacy.And in order to improve creepage distance and anti-breakdown performance, need to strengthen the diameter of the silicon rubber umbrella wing, but after having strengthened umbrella wing diameter, cause the distortion, sagging of the umbrella wing, not only have influence on and hang construction, also cause the interplane short circuit accident of umbrella to occur, made its demand that can not adapt in actual applications high-grade voltage circuit, also inconvenient maintaining.In order to address these problems, designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
This goal of the invention of the present utility model is larger in order to overcome above-mentioned silicon rubber umbrella wing diameter, umbrella wing quantity is on the low side and by the outside upwardly extending structure of the improved insulator of present inventor (number of patent application: 201320519566.6), although solved this problem, but increased the problem that insulator dead weight brings and put forward.A kind of composite suspension type insulators that increases chapeau de fer coated Si rubber full skirt is provided.
Technical solution of the present utility model is to realize like this, this kind increases the composite suspension type insulators of chapeau de fer coated Si rubber full skirt, there is the chapeau de fer (1) and the steel pin (5) that on the inside and outside wall of insulator (3), are fixedly connected by cement glue (2), on chapeau de fer, there is at least one chapeau de fer boss (6), there is silicon rubber full skirt (4) at the outer surface of chapeau de fer and steel pin and insulator, it is characterized in that the silicon rubber full skirt at chapeau de fer outer wall place extends to the position of chapeau de fer boss (6).
Useful technique effect of the present utility model is: increased the thickness of silicon rubber cluster parachute root and the range comprehension to chapeau de fer outer surface, like this, whole composite suspension type insulators can increase the quantity of the umbrella wing under the prerequisite that has reduced silicon rubber umbrella wing diameter, the weight that is unlikely to again to bring because insulator outwards and upwards extends increases, the deadweight of insulator is not increased substantially, can meet high voltage length under any condition needs apart from power transmission and transformation.And can easily realize and reduce umbrella footpath, increase umbrella number, increase creepage distance, strengthen that product resistance to punctures, resistance to steep wave impact property, improve product overall performance, reduce in use when being struck by lightning or the destroyed rate of overvoltage after impacting, improve product useful life.
Accompanying drawing explanation
Accompanying drawing is structural profile schematic diagram of the present utility model.Sequence number in accompanying drawing is: 1, chapeau de fer, 2, cement glue, 3, insulator, 4, silicon rubber full skirt, 5, steel pin, 6, chapeau de fer boss.
Embodiment
Below in conjunction with the embodiment providing in accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this kind increases the composite suspension type insulators of chapeau de fer coated Si rubber full skirt, there is the chapeau de fer (1) and the steel pin (5) that on the inside and outside wall of insulator (3), are fixedly connected by cement glue (2), on chapeau de fer, there is at least one chapeau de fer boss (6), there is silicon rubber full skirt (4) at the outer surface of chapeau de fer and steel pin and insulator, it is characterized in that the silicon rubber full skirt at chapeau de fer outer wall place extends to the position of chapeau de fer boss (6).
Owing to having increased coated height and the thickness of silicon rubber to chapeau de fer outer wall, can reduce smoothly umbrella footpath, increase umbrella number, simultaneously, the weight of composite suspension type insulators itself increases seldom, like this, creepage distance can increased, strengthen that product resistance to punctures, resistance to steep wave impact property, improve product overall performance, reduce in use when being struck by lightning or suffering the destroyed rate after overvoltage is impacted, when improving product useful life, improve the group number that insulator hangs, the needs of voltage power transmission and transformation line so that adaptation is upgraded
Boss on chapeau de fer can increase the structural strength of chapeau de fer; fixture clamping while meeting line attendant replacing insulator; improve the reliability that assembling and positioning is installed; upwards extension of the silicon rubber of chapeau de fer outside; both increased the protection to chapeau de fer outer wall; creepage distance and the breakdown characteristics that can improve again whole insulator, have larger application value.
Claims (1)
1. one kind increases the composite suspension type insulators of chapeau de fer coated Si rubber full skirt, there is the chapeau de fer (1) and the steel pin (5) that on the inside and outside wall of insulator (3), are fixedly connected by cement glue (2), on chapeau de fer, there is at least one chapeau de fer boss (6), there is silicon rubber full skirt (4) at the outer surface of chapeau de fer and steel pin and insulator, it is characterized in that the silicon rubber full skirt at chapeau de fer outer wall place extends to the position of chapeau de fer boss (6).
