Description
Technical field
The present invention relates to a kind of extra-high voltage sleeve pipe, a kind of new structure ultrahigh voltage direct current wall bushing.
Background technology
Along with the development of national economy, resident and the surge of industrial electricity, transportion wire road electric pressure is to supertension
Developing with extra-high voltage direction, domestic beginning builds extra-high voltage 1100kV exchange transportion wire road and ± 800kV direct current conveying circuit,
And planning construction ± 1100kV direct current conveying circuit, the extra-high voltage direct-current sleeve pipe therefore matched with transportion wire road has wide
Market prospect.
Direct-current wall bushing uses glue impregnated paper condenser type, two glue impregnated paper condenser-type terminal connection of general employing the most both at home and abroad
Knot composition, lower insulation position fills SF6 gas-insulated.This casing wt weight, the production cycle is long, and price is high, and DC bushing is due to outward
Portion's voltage's distribiuting is uneven, and sleeve pipe maker generally increases external insulation dry arcing distance and solves, and which not only adds product
Cost, too increases the manufacture difficulty of product.
Summary of the invention
The technical problem to be solved is, overcomes the deficiencies in the prior art, it is provided that a kind of extra-high voltage direct-current is through walls
Sleeve pipe, this sleeve pipe is with short production cycle, lightweight, low cost of manufacture, bending strength are high, safe and reliable to operation, significantly improves electrically
Performance.
In order to solve above technical problem, the ultrahigh voltage direct current wall bushing that the present invention provides, including: it is fixed on ground connection cylinder
The insulated part of both sides, runs through the high-field electrode of described insulated part, and is fixed on the ground electrode of ground connection cylinder inwall, its feature
It is: described insulated part at least has two adjacent sub-set pipes, is fixed as one by rebound between adjacent sub-set pipe,
Described wall bushing is internally provided with the target between ground electrode and high-field electrode, the two ends of described target
Fixed by two rebounds respectively, sub-set pipe internal surface uniform winding enamel-cover resistance wire.
In order to solve above technical problem further, the present invention also has the feature that
1, described insulated part outer end is provided with end plate.
2, described sub-set tube-surface has silicon rubber umbrella.
3, equipped with end shield measurement terminal, current transformer and for being arranged on the flange arrangement of body of wall at ground connection cylinder.
4, described sub-set pipe is glass steel material.
5, described sub-set pipe is fixing with mucilage binding between rebound and end plate is connected.
6, high-field electrode and upper head plate and bottom plate short circuit, target and upper end rebound and lower end rebound short circuit.
7, insulation gas filled in sleeve pipe.
8, described insulating gas is sulfur hexafluoride.
Two ends of the present invention insulated part is divided into two or more sub-set pipe, centre to be connected by rebound, sub-set tubing matter
For fiberglass, outer surface has silicon rubber umbrella, for solving the uneven situation of outer surface voltage that sub-set pipe causes, at sub-set pipe
Inner surface uniform winding enamel-cover resistance wire, this layer of enamel-cover resistance wire can make sub-set tube-surface distribution of resistance more uniform, work as height
When having space charge to occur at pressure, can be discharged by enamel-cover resistance wire, performance is put in the office being greatly improved product.Each parts are straight
Connecing employing mucilage binding structure, add the bulk strength of product, the production cycle shortens, and (only paper condenser is through walls for weight
/ 4th of casing wt), manufacturing cost reduces, bending strength is high and safe and reliable to operation.
High-field electrode carries ballast current conductor as sleeve pipe, is in high potential.Target and two ends rebound connect, three
Isoelectric level, is calculated by design, makes voltage at target be about the half of terminal voltage.Ground electrode and ground connection cylinder are even
Connect, be in earth potential.Ensure the piece electrical performance of sleeve pipe.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail.But the invention is not restricted to given example.
As it is shown in figure 1, the present embodiment ultrahigh voltage direct current wall bushing, including: it is fixed on the insulated part of ground connection cylinder both sides,
Run through the high-field electrode of insulated part, and be fixed on the ground electrode of ground connection cylinder inwall.At ground connection cylinder equipped with end shield measurement terminal,
Current transformer and for being arranged on the flange arrangement of body of wall.Sleeve pipe ensures cannula tip by spring structure 7 and sealing member
Seal, in sleeve pipe, fill SF6 insulating gas 10.Insulated part outer end is provided with end plate.(connect as a example by the insulated part of top in scheming
Cylinder both sides, ground insulation system is identical), insulated part has two sub-sleeve pipes: save in insulation and insulate lower joint, and in insulation, joint is with exhausted
It is fixed as one by rebound between joint under edge.In insulation, joint and the lower joint surface of insulation are with silicon rubber umbrella, and insulation saves
With insulation lower joint inner surface uniform winding enamel-cover resistance wire, can uniformly external insulation sheet resistance be distributed, the harmful sky of release in time
