Abstract
The utility model discloses an ultra-high voltage AC-DC porcelain pillar insulator. The ultra-high voltage AC-DC porcelain pillar insulator is formed by connecting two groups of pillar insulators through flanges, wherein the uppermost end is a group of solid pillar insulators, the lower is a group of hollow pillar insulators, and the hollow pillar insulator is composed of an upper flange, a lower flange, a hollow porcelain bushing and an internally filled low-density flame-retardant and moisture resistant high-molecular insulating material. The ultra-high voltage AC-DC porcelain pillar insulator has the advantages of light weight, high intensity and excellent electrical performance.
Description
Technical field
The utility model relates to a kind of extra-high voltage alternating current-direct current porcelain strut insulator.
Background technology
Development along with national economy, the surge of resident and industrial electric weight, transportion wire road electric pressure is to superhigh pressure and ultra high voltage future development, domestic start to build ultra high voltage 1100kV exchange the transportion wire road and ± 800kV direct current conveying circuit, and planning construction ± 1100kV direct current conveying circuit, therefore and the ultra-high-voltage post insulator that matches of transportion wire road wide market prospects are arranged.
The post insulator that applies to now extra high voltage line is two kinds of composite insulator and solid core insulation, and subject matter has:
The composite post insulator used now is substantially all solid, has two problems:
1.1 solid strut insulator Heavy Weight, cost is high, because technological problems need to divide several times, solidifies.
1.2 the solid bar amount of deflection is large, stressed lower easy bending may affect the security of operation of equipment,
Present part post insulator is the mode of useful hollow insulating cylinder also, and for reaching the bending strength of regulation, diameter is very large, and inner hollow insulation is also a great problem.
Present solid heart post insulator weight is large, and producting process difficulty is large and power consumption is large; Because weight own is large, the dead-load moment that stressed bending is subject to is also very large, may affect the equipment security of operation.
Summary of the invention
The problem existed in order to overcome prior art, the purpose of this utility model is to provide a kind of extra-high voltage alternating current-direct current porcelain strut insulator, this extra-high voltage alternating current-direct current porcelain strut insulator bending strength is large, lightweight, improve insulator internal electric intensity, guaranteed the whole good electric property of insulator.
The purpose of this utility model is achieved through the following technical solutions:
A kind of extra-high voltage alternating current-direct current porcelain strut insulator is characterized in that: this insulator comprises one group of solid strut insulator and one group of Hollow Pillar insulator, and the solid strut insulator is arranged on Hollow Pillar insulator upper end.
In the utility model, described Hollow Pillar insulator comprises upper flange, hollow insulator, filler and lower flange, and filler is the damp insulating polymeric material of the fire-retardant resistance of low-density; Upper flange and lower flange and hollow insulator outside fill with cement gel, inner with organic Materials with High Strength hermetically mucilage binding together, filler is filled in hollow insulator.Be provided with in upper flange and encircle in upper flange, in lower flange, be provided with in lower flange and encircle; Upper flange and lower flange outside fill with cement gel, and mucilage binding is on hollow insulator hermetically by organic Materials with High Strength for interior ring, and in flange, ring is higher than the flange outer shroud.
The beneficial effects of the utility model are:
1, set up interior ring on flange, analyze from the engineering loading angle, increased the lifting surface area of porcelain piece and be subject to force component, greatly improved the bending strength of post insulator.
2, by raising interior ring height, improve the critical section position, optimized product distribution of force situation, and because increasing the flange height, do not reduced product dry arcing distance (increase outer shroud and can shorten the product dry arcing distance), affected the product electric property.
3, one group of upper end is solid heart post insulator, one group of lower end is porcelain Hollow Pillar insulator, in the Hollow Pillar insulator, ring is higher than the flange outer shroud, and the mucilage binding height uprises, and improves bending strength, because the insulating polymeric material that the inside packed density is little, do not need to increase the dry arcing distance of insulator, therefore can effectively reduce weight and the height of insulator, thereby reduce the insulator height, improve insulator internal electric intensity, guaranteed the whole good electric property of insulator.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The structural representation that Fig. 2 is the utility model hollow core insulator.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of extra-high voltage alternating current-direct current porcelain strut insulator described in the utility model, connected to form by flange by two groups of post insulators altogether.One group of upper end is solid strut insulator 1, below one group be Hollow Pillar insulator 2; Lower end Hollow Pillar insulator 2 is divided into upper flange 21, hollow insulator 22, filler 23 and lower flange 24; Filler is the damp insulating polymeric material of the fire-retardant resistance of low-density, wherein upper flange 21 and lower flange 24 are provided with ring 25 and the interior ring 26 of lower flange in upper flange, in upper flange, the height of ring is higher than the upper flange outer shroud, in lower flange, the height of ring is higher than the lower flange outer shroud, hollow insulator is contained in cement gel between the outer shroud of upper and lower flange, with organic Materials with High Strength mucilage binding between the interior ring of upper and lower flange.
During making, at first by upper flange, lower flange together with hollow insulator adhesive binding, then be filled with the damp insulating polymeric material of the fire-retardant resistance of low-density as filler in hollow insulator, finally each joint solid strut insulator and Hollow Pillar insulator fitted together and get final product.
