Abstract
A composite disk-type insulator relates to an insulator and solves the problems that a conventional suspension insulator is poor in antifouling performance, is cumbersome and has large maintenance workload, string breakage failure frequently occurs, and an outer insulating core rod and an internal insulating core rod are easy to damage to cause accidents. The composite disk-type insulator comprises an external fitting seat, an external umbrella skirt, an internal umbrella skirt, an internal fitting seat, a metal pull rod and a ball head, wherein the external fitting seat, the external umbrella skirt and the internal umbrella skirt are sequentially connected from the top down; the upper end of the internal fitting seat sequentially penetrates the middles of both the internal umbrella skirt and the external umbrella skirt to be inserted into the inner chambers of the fitting seats; the upper end of the metal pull rod is inserted into the internal fitting seat, whereas the lower end of the metal pull rod is integrally and fixedly connected with the ball head; the ball head is exposed outside the lower surface of the internal umbrella skirt; an open slot is formed at the upper end of the external fitting seat; and the width of the open slot is smaller than that of the upper end surface of the metal pull rod. The insulator provided by the invention is suitable for high-voltage power transmission.
Description
Technical field
The present invention relates to a kind of insulator, be specifically related to a kind of compound disk insulator.
Background technology
Suspension insulator is the visual plant of electricity generation system and transmission system, and at present, suspension insulator used in the electric power system has: ceramic disc insulator, glass disc insulator, bar type compound inslation substring.Electric power system operation practice for many years shows that ceramic disc insulator shortcoming has: often fall to go here and there phenomenon, pottery belongs to hydrophilic material, and antifouling property is poor, needs detection " null value " porcelain vase regularly, and maintenance workload is big, and weight is big; The shortcoming of glass fibre reinforced plastic insulating is: the same hydrophilic material that belongs to of fiberglass with pottery, and antifouling property is poor, and it is bigger regularly to clean maintenance workload, and volume is heavy, falls the string problem and often takes place, and " null value " problem occurs with the form of blast; Though bar type compound inslation substring does not have above-mentioned shortcoming; But the length of 220KV and the above every string of bar type compound inslation is all more than 2 meters, particularly 500KV and above electric pressure, and every string length is all more than 5 meters; Transportation and construction are all very inconvenient; And because oversize, the accident of damage insulator external insulation plug and interior insulation mandrel often has generation, stays hidden danger for the safe operation of electrical network.
Summary of the invention
The present invention is poor for solving existing suspension insulator antifouling property, often falls to go here and there phenomenon, the volume heaviness, and maintenance workload is big, and often damages external insulation plug and the accidents caused problem of interior insulation mandrel, and then proposes a kind of compound disk insulator.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes outer gold utensil seat, external shed, interior full skirt, interior gold utensil seat, metal pull bar and bulb; Outer gold utensil seat, external shed, interior full skirt from top to bottom connect successively; The middle part that the upper end of interior gold utensil seat is passed interior full skirt, external shed from the bottom to top successively is inserted in the inner chamber of outer gold utensil seat; In the gold utensil seat, the lower end of metal pull bar and bulb are affixed to be integral in the upper end of metal pull bar was inserted into, and bulb is exposed at outward outside the lower surface of interior full skirt; The upper end of outer gold utensil seat is provided with open slot, and the width of rebate of open slot is less than the width of metal pull bar upper end end face.
The invention has the beneficial effects as follows: the width of metal pull bar of the present invention upper end end face is greater than the width of outer gold utensil seat upper shed groove, so stopped in transmission line, to fall the phenomenon generation of string; The angle of inclination on external shed surface is more than 2 times of traditional bar type composite insulator, has further improved the self-cleaning ability on external shed surface; High strength glass fiber insulation filling layer between metal pull bar and outer gold utensil seat can because of the variation of ambient temperature or vibrations crack or broken, can stop the problem of " null value "; External shed and interior full skirt adopt silastic material, and weight reduces greatly, can realize non-maintaining; The present invention adopts the combination of different disk tracks to realize anti-pollution flashover, anti-birds droppings evil, put ice sudden strain of a muscle, rainproof sudden strain of a muscle; The present invention has reduced the capital expenditure of electrical network under the prerequisite of the security reliability that improves electrical network, reduced the operating cost of electrical network.
