Abstract
A kind of 330KV high-voltage terminal devices, its structure is：Aluminium foil is surrounded by outside cable, aluminium foil is coated with crimped paper, crimped paper is coated with strap, above construction packages are in insulating cylinder, stay is provided between insulating cylinder outer shroud week and strap inner periphery, stay makes to be supported by gap between insulating cylinder and strap and is mutually not in contact with each other, and oil is inoculated with the gap between insulating cylinder and strap, and described gap forms insulating oil duct.The utility model passes through said structure, there is provided a kind of simple structure, using effect are good, with short production cycle and reduce the outgoing line device of manufacturing cost.
Description
Technical field
The utility model is related to a kind of outgoing line device, especially a kind of 330KV high-voltage terminal devices.
Background technology
Now, domestic many areas are 330KV power networks, with the improvement of aluminium industrial situation, the use of 330KV outlet structures
More and more extensively, existing outlet structure, complex structure are long in time limit, and cost is higher, it is necessary to through the manufacturer production that insulate.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of 330KV high-voltage terminal devices, and its structure is：
Aluminium foil is surrounded by outside cable, aluminium foil is coated with crimped paper, and crimped paper is coated with strap, and above construction packages are in insulating cylinder
In, stay is provided between insulating cylinder outer shroud week and strap inner periphery, stay makes to be supported by gap between insulating cylinder and strap
Mutually it is not in contact with each other, oil is inoculated with the gap between insulating cylinder and strap, described gap forms insulating oil duct.Solve existing skill
Due to producing long in time limit and cost technical problem high caused by outlet structure complexity present in art,
To achieve these goals, the technical solution adopted in the utility model is：330KV high-voltage terminal devices, its feature
It is：Aluminium foil is surrounded by outside cable, aluminium foil is coated with crimped paper, and crimped paper is coated with strap, and above construction packages exist
In insulating cylinder, stay is provided between insulating cylinder outer shroud week and strap inner periphery, stay makes to be supported between insulating cylinder and strap
There is gap not contact mutually, oil is inoculated with the gap between insulating cylinder and strap, described gap forms insulating oil duct.
Described insulating cylinder is provided with five layers altogether, fixes support using stay between every layer of insulating cylinder, and be formed with absolutely
Edge oil duct.
Stay described in described edge cylinder is uniformly distributed, and four stays are provided with every layer of insulating cylinder.
Between described insulating cylinder, square ring is provided with.
The beneficial effects of the utility model are：Utility model provides a kind of 330KV high-voltage terminal devices, its structure
For：Aluminium foil is surrounded by outside cable, aluminium foil is coated with crimped paper, and crimped paper is coated with strap, and above construction packages are exhausted
In edge cylinder, stay is provided between insulating cylinder outer shroud week and strap inner periphery, stay makes to be supported by between insulating cylinder and strap
Gap is mutually not in contact with each other, and oil is inoculated with the gap between insulating cylinder and strap, and described gap forms insulating oil duct.This practicality is new
Type pass through said structure, there is provided a kind of simple structure, using effect it is good, with short production cycle and it is low cost of manufacture go out it is traditional thread binding
Put.
Brief description of the drawings
Fig. 1：It is utility model structural representation.
Fig. 2：It is Fig. 1 along A-A faces view.
Specific embodiment
330KV high-voltage terminal devices, its structure is：Aluminium foil 2 is surrounded by outside cable 1, aluminium foil is coated with crimped paper 3,
Crimped paper 3 is coated with strap 4, and above construction packages are all and the inner periphery of strap 4 between in the outer shroud of insulating cylinder 5 in insulating cylinder 5
It is provided with stay 7, stay 7 makes to be supported by gap between insulating cylinder 5 and strap 4 and is mutually not in contact with each other, between insulating cylinder 5 and strap 4
Gap in be inoculated with oil, described gap forms insulating oil duct.
Described insulating cylinder 5 is provided with five layers altogether, fixes support using stay 7 between every layer of insulating cylinder 5, and be formed with
Insulating oil duct.
Stay 7 described in described edge cylinder 5 is uniformly distributed, and four stays 7 are provided with every layer of insulating cylinder 5.
Between described insulating cylinder 5, square ring 8 is provided with.It is specific by outside interior, the 3rd, 4,5, the appearance of layer insulating cylinder 5
Square ring 8 is provided with face.The square ring 8 set on described three-layer insulated cylinder 5 is by innermost layer to outermost layer successively away from cable 1
Leading-out terminal set, and the distance between internal layer is equal, and the shape of square ring 8 is consistent with electric field equipotential wire shaped at its position, is used for
The possibility that creeping discharge occurs is reduced, the dielectric strength of end construction is improved.
