Abstract
The utility model discloses a bell jar type composite disc insulator which is characterized by being formed by a glass insulator, a coupling agent layer, an outer shed, an inner shed and a non-composite silicone rubber area. A silicon rubber layer is respectively combined on the upper surface and the lower surface of the insulator, the insulator extends, and a layer of coupling agent is arranged between interfaces of the insulator, the composite silicon rubber layer and the glass (ceramic) insulator are cast into one body firmly through the coupling agent, and the non-composite silicone rubber area is arranged on the lower surface of the glass (ceramic) insulator. The bell jar type composite disc insulator is light in weight, strong in self-cleaning capacity, safe and reliable, achieves maintenance free in operation of a power grid, and reduces operation cost of the power grid. Simultaneously, creepage distance of a single insulator is large, anti-over-voltage capacity is strong without increasing the number of insulators on a power transmission line, and the bell jar type composite disc insulator can be widely applied to a 35KV-1000KV power transmission line and has good economic benefit and social benefit. In addition, the non-composite silicone rubber area is arranged under the glass insulator, can prevent the characteristics of zero explosion of toughened glass from being blocked, and facilitates line walkers to find fault points in time.
Description
Technical field
The utility model relates to electric power transmission line and transformer station, and is special relevant with the suspension type disc insulator of high pressure, superhigh pressure and ultra high voltage, specifically is the compound disk insulator of a kind of bell jar type.
Background technology
Suspension insulator is the visual plant of transmission of electricity and electricity generation system, and used suspension insulator has pottery, glass suspension insulator and clavate composite insulator at present.Preceding two kinds of Heavy Weights, the operation maintenance workload is big, and then a kind of is clavate compound inslation substring; Though in light weight, non-maintaining, very long transportation of insulator string and construction are all inconvenient; And external insulation in the unavoidable clashing and breaking hides some dangers for for the safe operation of electrical network in carrying and installation process, and " the compound disk insulator of bell jar type " inventor applied in 2011 once that application number was 201120468306.1 patents for this reason; Although this patent has antifouling preferably ability,, be applied on 220KV and the above transmission line through experiment back proof repeatedly; Its reliability does not reach 100%, and therefore, the applicant has designed the compound disk insulator of bell jar type again.
The utility model content
The purpose of the utility model is for addressing the above problem, provide a kind of resistance tocrocking good, and anti-damage to crops caused by thunder ability is strong, can realize the non-maintaining compound disk insulator of bell jar type.
The technical problem of the utility model is to solve like this; The compound disk insulator of a kind of bell jar type; The composite silicone rubber zone constitutes to it is characterized in that reaching by glass (pottery) insulator, coupling agent layer, external shed, interior full skirt; The upper and lower surface recombination of glass (pottery) insulator has silastic-layer and extends; One deck coupling agent is arranged between its interface, make compound silastic-layer and insulator cast solid regularly through coupling agent, the lower surface of glass (pottery) insulator also is provided with not composite silicone rubber zone.
According to the compound disk insulator of the described bell jar type of the utility model, it is characterized in that silastic-layer is compounded on the complete glass or ceramic insulator.
The utility model is in light weight, self-cleaning ability is strong, it is non-maintaining to realize in the operation of power networks, reduce operation of power networks cost, safe and reliable.Because the creepage distance of monolithic insulator is big, do not increase at transmission line under the situation of insulator sheet number simultaneously, the ability of anti overvoltage is stronger, has favorable economic benefit and social benefit so be widely used in the compound disk insulator of 35KV-1000KV.Be provided with the not zone of composite silicone rubber below the not outer glass insulator, its effect is that the broken quick-fried characteristics of toughened glass " null value " can be obstructed, and utilizes the circuit patrolman in time to find the fault point.

Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of looking up of Fig. 1.
Among the figure 1, glass (pottery) insulator; 2, coupling agent layer; 3, external shed; 4, interior full skirt; 5, composite silicone rubber is not regional.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1, shown in 2; The compound disk insulator of a kind of bell jar type; Reach not composite silicone rubber zone 5 formations by glass (pottery) insulator 1, coupling agent layer 2, external shed 3, interior full skirt 4, the upper and lower surface recombination of glass (pottery) insulator has silastic-layer and extends, and one deck coupling agent layer 2 is arranged between its interface; Make compound silastic-layer and glass (pottery) insulator cast solid securely through coupling agent, the lower surface of glass (pottery) insulator 1 also is provided with not composite silicone rubber zone.
