Abstract
The invention discloses a novel composite suspended type disc-shaped insulator with an improved structure. The novel composite suspended type disc-shaped insulator is provided with an iron cap and a steel foot, wherein the iron cap and an inner core of the insulator are integrally bonded by an iron-cap bonding agent; the steel foot and the inner core and the insulator are integrally bonded by a steel-foot bonding agent; silicone-rubber umbrella wings are arranged on the outer surface of the inner core of the insulator; at least one circle of ring groove is formed in the inner core of the insulator; the bonding agent is used for filling and curing between the ring groove and the outer wall of the iron cap. The novel composite suspended type disc-shaped insulator disclosed by the invention has the advantages that due to the structure characteristics of the ring groove, the axial size of the inner core of the insulator is increased, the diameter of the silicone-rubber umbrella wings is reduced, the quantity of the umbrella wings are increased, the creepage distance is increased, the use performance of a product and the whole performance of the product are improved, the broken rate when the product is stuck by lightning or impacted by voltage in use is reduced and the service life of the product is prolonged; when the insulator is constructed and maintained, the suspending operation is simple and convenient; by preliminary test in a factory, the creepage distance can be increased by 80%-250%, and the promotion and application values are extremely high.
Description
Technical field
The invention belongs to the dish-type composite insulator used in power circuit, definite saying is a kind of NEW TYPE OF COMPOSITE suspension type disc insulator that improves structure.
Background technology
Compound dish-type insulator for 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, the umbrella wing at 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 caused the inevitable problem existed in a manufacture and actual the 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,, very easily lost efficacy under strict experiment condition and the mal-condition in practical application in steep wave, creepage experiment etc.And the structure of chapeau de fer to be also its inwall solidify and be connected by binding agent and inner core always, because its connection power is less, cause its suspension force also to be difficult to improve, power and just formed the bottleneck of insulator restricted number for extra-high pressure.And wear performance in order to improve creepage distance and resistance, need to strengthen the diameter of the silicon rubber umbrella wing, but after having strengthened umbrella wing diameter, caused 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 it can not adapt to the demand of high-grade voltage circuit in actual applications, also inconvenient maintaining.In order to address these problems, the present inventor has done research in earnest, has proposed goal of the invention of the present invention.
Summary of the invention
Goal of the invention of the present invention is larger in order to overcome above-mentioned silicon rubber umbrella wing diameter, and the umbrella wing quantity problem of bringing on the low side puts forward.A kind of NEW TYPE OF COMPOSITE suspension type disc insulator that improves structure is provided.
Technical solution of the present invention is to realize like this, this kind improves the NEW TYPE OF COMPOSITE suspension type disc insulator of structure, there is chapeau de fer (1) and steel pin (7), chapeau de fer (1) is bonded as one by chapeau de fer binding agent (2) and insulator inner core (4), steel pin (7) is bonded as one by steel pin adhesive (3) and insulator inner core (4), there is the silicon rubber umbrella wing (5) in the outside of insulator inner core, it is characterized in that thering is at least one ring groove (6) on the insulator inner core, between the outer wall of this annular groove and chapeau de fer, by binding agent, fill and solidify.
Useful technique effect of the present invention is: due to the design feature of annular groove, increased the axial dimension of insulator inner core, reduced the diameter of the silicon rubber umbrella wing, increase umbrella wing quantity, increased creepage distance, improve the serviceability of product and the overall performance of product, reduced in use when being struck by lightning or suffering the destroyed rate after overvoltage is impacted, improved product useful life.And, when the insulator construction maintenance, suspension operational is simple and convenient.Through preliminary test in factory, creepage distance can improve 80%～250%, has great application value.And, the outer wall of chapeau de fer also is cured as one by the annular groove of binding agent and inner core, greatly improve its connection power, effectively overcome superhigh pressure supply line due to the hypodynamic bottleneck of the suspension of composite suspension type insulators, obtained beyond thought actual track result of use.
The accompanying drawing explanation
Accompanying drawing is structure semi-section schematic diagram of the present invention.Sequence number in accompanying drawing is: 1, chapeau de fer, 2, the chapeau de fer adhesive, 3, steel pin adhesive, 4, the insulator inner core, 5, the silicon rubber umbrella wing, 6, annular groove, 7, the steel pin, 8, annular projection.
Embodiment
Below in conjunction with the embodiment provided in accompanying drawing, structure of the present invention and use are elaborated.With reference to accompanying drawing, this kind improves the NEW TYPE OF COMPOSITE suspension type disc insulator of structure, there is chapeau de fer (1) and steel pin (7), chapeau de fer (1) is bonded as one by chapeau de fer binding agent (2) and insulator inner core (4), steel pin (7) is bonded as one by steel pin adhesive (3) and insulator inner core (4), there is the silicon rubber umbrella wing (5) in the outside of insulator inner core, it is characterized in that thering is at least one ring groove (6) on the insulator inner core, between the outer wall of this annular groove and chapeau de fer, by binding agent, fill and solidify.
There is through hole on the sidewall of said chapeau de fer (1).
Said umbrella wing quantity is 1 to 12.
The umbrella wing quantity of optimizing is 2 to 8.
Optimized umbrella wing quantity is 3 to 7.
Further umbrella wing quantity can be 46, under exquisite condition, can be 4 to 5 umbrella wings.
In order to improve the positioning precision of suspension insulator, convenient maintenance and the needs of manufacturing, on the outer wall of said chapeau de fer, design has the projection (8) of a ring-type.
Design feature due to the annular groove on dish-type insulator inner core, be equivalent to increase the axial dimension of dish-type insulator inner core, like this, the quantity of its outer field silicon rubber umbrella wing can be arranged according to best umbrella wing structure, can be increased to 4 to 6 umbrella wings by maximum 3 the umbrella wings of 2 original umbrella wings easily.Obviously, the quantity of the umbrella wing has increased, and its corresponding creepage distance also just increases thereupon, not changing under the prerequisite that meets disc insulator overall weight and creepage distance, can reduce the diameter of composite suspension type insulators.That is: be equivalent to method by increasing umbrella wing quantity offset umbrella wing diameter reduce with the minimizing of creepage distance, improved the resistance to sparking energy of insulator.So both facilitated to manufacture and installed, and also given and safeguard that replacing has brought huge convenience.After having shortened the diameter of the umbrella wing, the distortion of silicon rubber insulator has also reduced simultaneously, and like this, operation and maintenance is also very convenient.
