Abstract
The utility model discloses a hollow disc type composite insulator comprising a hardware seat, a metal pull rod, stuffing, a ceramic core, an external and an internal umbrellas, and a trumpet-shaped umbrella. The stuffing in a cavity of the hardware seat adheres the hardware seat, a metal pull rod and a ceramic core together. The external umbrella and the internal umbrella formed by mould pressing are compounded on the ceramic core and the trumpet-shaped umbrella is extended upward from the inclined bottom of the ceramic core. Small umbrellas around the metal pull rod below the ceramic core are integrated with. The external and internal umbrellas and a trumpet-shaped umbrella are adhered by coupling agent. The internal umbrella made of silicon rubber can increase the creep distance and mechanical strength thereof. The small umbrellas at the lower part of the ceramic core is an observation point for a transmission line attendant to check whether the ceramic core is intact in the operation process by a telescope when inspection of transmission line. Compared with conventional ceramic bottle or glass steel disc type insulator, the ceramic core possesses reduced weight, strong self-clean capacity, ice coating flashover and rainwater coating flashover prevention, lowered grid infrastructure investment and operation cost, and application to 35KV-1000KV transmission lines.
Description
Technical field
The utility model is that electric power transmission equipment, particularly high pressure, superhigh pressure are relevant with ultra high voltage suspension type disc insulator, specifically is a kind of hollow disc type composite insulator.
Background technology
Suspension insulator is the visual plant of electricity generation system and transmission system, the suspension insulator that the current power transmission system is used: suspension porcelain insulator, fiberglass suspension insulator, bar type composite insulator.Electric power system operating experience for many years shows, pottery and fiberglass suspension insulator weight is big, maintenance workload is big.Bar type compound inslation substring; Though there is not above-mentioned shortcoming, the length of 220KV and above bar type compound inslation substring is all more than 2 meters, and particularly 500KV and the above every string length of electric pressure are more than 5 meters; Transportation and construction are all very inconvenient; And because oversize, the example of damage insulator external insulation and interior insulation happens occasionally, and stays hidden danger for the safe operation of electrical network.
The utility model content
The purpose of the utility model is in order to overcome above-mentioned deficiency, a kind of weight reduction greatly to be provided, to improve its self-cleaning ability, anti-ice sudden strain of a muscle and the strong hollow disc type composite insulator of rain sudden strain of a muscle ability.
The technical scheme of the utility model is achieved in that a kind of hollow disc type composite insulator; It is characterized in that by comprising that gold utensil seat, metal pull bar, inserts, porcelain core, interior external shed, horn-like full skirt constitute; Be integral gold utensil seat, metal pull bar and porcelain core are bonding with the inserts of gold utensil seat inner chamber; On the porcelain core a compound external shed and an interior full skirt that is molded into external shed and porcelain core tiltedly below on the horn-like full skirt that stretches out; Little full skirt and the porcelain core established around the metal pull bar of porcelain core below are an integral body, and interior external shed and horn-like full skirt combine through coupling agent with the porcelain core interface.
According to the hollow disc type composite insulator described in the utility model, it is characterized in that interior external shed, its material of horn-like full skirt are silica gel, the packing material material is a high-strength adhesive, the porcelain core material is that pottery or fiberglass all can.
The utility model adopts porcelain core and silica gel contact-making surface to keep coarse in order to make firm bonding of silica gel and porcelain core, and silica gel is pressed in before the porcelain core with press moulding mode, and porcelain core is coated with coupling agent on the interface, generation molecular effect after vulcanizing.Little full skirt around the metal pull bar below the porcelain core is in order to observe porcelain core whether the point of observation of damage to be arranged, and can in time get rid of hidden danger.External shed is molded into one in the silica gel, can strengthen the mechanical strength of full skirt, has increased the creepage distance of the utility model again.The utility model and traditional disk insulator compare, and have fully used the characteristics of the hydrophobicity of silica gel, and hollow disc type composite insulator clean surfaces power is strong, utilizes the characteristic of silica gel light specific gravity, makes the weight saving of hollow disc type composite insulator a lot.The creepage distance of hollow disc type composite insulator increases about 25% than unidimensional traditional disk insulator, the anti-soil that has improved transmission line dodges, and ice dodges the ability with the rain sudden strain of a muscle.Under the precondition of the security reliability of the utility model realization raising electrical network, can effectively reduce the electrical network capital expenditure, reduce the operation of power networks cost, have tangible economic benefit and social benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model
Among the figure: 1-gold utensil seat, 2-metal pull bar, 3-inserts, full skirt in 4-pottery or the glass steel core, 5-, 6-external shed, the little full skirt of 7-porcelain or fiberglass, the horn-like full skirt of 8-.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Shown in the figure: hollow disc type composite insulator; Comprise gold utensil seat 1, metal pull bar 2, inserts 3, porcelain core 4, interior full skirt 5, external shed 6; Pottery or fiberglass umbellule skirt 7, horn-like full skirt 8 constitute; Inserts 3 with gold utensil seat inner chamber links into an integrated entity gold utensil seat 1, metal pull bar 2 and porcelain core 4; On the porcelain core 4 compound external shed 6 and the interior full skirt 5 that is molded into external shed and porcelain core tiltedly below on the horn-like full skirt 8 that stretches out, little full skirt and the porcelain core 4 established around the metal pull bar 2 of porcelain core 4 belows are an integral body, interior external shed 5 and horn-like full skirt 8 combine through coupling agent with porcelain core 4 interfaces.
External shed, its material of horn-like full skirt are silica gel in said, and the packing material material is a high-strength adhesive, and the porcelain core material is that pottery or fiberglass all can.
The utility model adopts ceramic core 4 and silica gel contact-making surface to keep coarse in order to make firm bonding of silica gel and porcelain core, and silica gel is pressed in before the ceramic core 4 with press moulding mode, and ceramic core is coated with coupling agent on the interface, generation molecular effect after sulfuration.Umbellule skirt 7 around the metal pull bar 2 below the ceramic core 4 is in order to observe ceramic core 4 whether the point of observation of damage to be arranged, and can in time get rid of hidden danger.External shed is molded into one in the silica gel, can strengthen the mechanical strength of full skirt, has increased the creepage distance of the utility model again.
The hollow disc type composite insulator of the utility model is applicable to the use of 35KV-1000KV transmission line, and effectively reduces electrical network capital expenditure and operating cost.
