Abstract
The utility model discloses an extra-high voltage AC/DC composite supporting insulator comprising a lower flange, an upper flange, an inner FRP (fiber reinforced polymer) cylinder and an outer FRP cylinder. The upper flange is provided with an upper flange inner ring and an upper flange outer ring. The lower flange is provided with a lower flange inner ring and a lower flange outer ring. The upper flange inner ring and the lower flange inner ring are casted together with the inner FRP cylinder and the outer FRP cylinder. The upper flange outer ring and the lower flange outer ring are casted together with the outer FRP cylinder. Low-density anti-flaming and moisture-proof high-molecular insulation materials are filled between the inner FRP cylinder and the outer FRP cylinder as well as inside the inner FRP cylinder. The surface of the outer FRP cylinder is bonded with a silicone rubber composite umbrella cover. The extra-high voltage AC/DC composite supporting insulator is reasonable in structure, strong in bending strength and small in curve; and the diameter of the required hollow insulation cylinder is small.
Description
Technical field
The utility model relates to a kind of post insulator, specifically a kind of ultrahigh voltage AC and DC composite post insulator.
Background technology
When the supports such as 750kV above switch, reactor and bus require bending strength higher with post insulator, with electroceramics, relatively be difficult to realize, especially 800kV above direct current post insulator, because creepage distance requires very high, can only adopt composite rod insulator (fuse glass steel material, outside with the compound umbrella cover of silicon rubber).The superhigh pressure composite post insulator used now mainly is divided into following two kinds:
1, the 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,
2, the present also mode of useful hollow insulating cylinder of part post insulator, for reaching the bending strength of regulation, diameter is very large, and inner hollow insulation is also a great problem.
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 ultrahigh voltage AC and DC composite post insulator, and this ultrahigh voltage AC and DC composite post insulator is rational in infrastructure, and required hollow insulating cylinder diameter is little, bending is little, bending strength is high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of ultrahigh voltage AC and DC composite post insulator, it is characterized in that: this insulator comprises lower flange, upper flange, interior glass fibre reinforced plastic cylinder and outer glass fibre reinforced plastic cylinder, be provided with ring and upper flange outer shroud in upper flange on upper flange, be provided with in lower flange ring and lower flange outer shroud on lower flange, in upper flange ring with in lower flange, encircle with interior glass fibre reinforced plastic cylinder with together with outer glass fibre reinforced plastic cylinder is cast in, upper flange outer shroud and lower flange outer shroud be with together with outer glass fibre reinforced plastic cylinder is cast in; Reach interior glass fibre reinforced plastic cylinder inside and be filled with the damp insulating polymeric material of the fire-retardant resistance of low-density between interior glass fibre reinforced plastic cylinder and outer glass fibre reinforced plastic cylinder, the glass fibre reinforced plastic cylinder surface binded has the compound umbrella cover of silicon rubber outside.
In the utility model, in described lower flange, the height of ring is higher than the lower flange outer shroud; In upper flange, the height of ring is higher than the upper flange outer shroud.Together with ring and encircling in lower flange is cast in by organic Materials with High Strength with outer glass fibre reinforced plastic cylinder with interior glass fibre reinforced plastic cylinder in upper flange; Together with the upper flange outer shroud is cast in by organic Materials with High Strength with outer glass fibre reinforced plastic cylinder with the lower flange outer shroud.
In the utility model, ring, higher than the flange outer shroud, together with respectively with two glass fibre reinforced plastic cylinder mucilage bindings, has increased the bending strength of product in flange, between outer glass fibre reinforced plastic cylinder and interior glass fibre reinforced plastic cylinder, is filled with insulating polymeric material, has guaranteed the dielectric strength between two end flanges.
The beneficial effects of the utility model are:
1, add a hollow insulating cylinder in hollow insulating cylinder again, from the engineering loading angle, carry out appropriate design, required hollow insulating cylinder diameter diminishes, and reduces bending.
2, at the inner damp insulating polymeric material of the fire-retardant resistance of low-density of filling of hollow insulator, utilize inner creeping discharge to coordinate characteristics, increase the height of metal part, improve bending strength.
The accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is implemented.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of ultrahigh voltage AC and DC composite post insulator described in the utility model, comprise lower flange 1, outer glass fibre reinforced plastic cylinder 4, damp insulating polymeric material 5, interior glass fibre reinforced plastic cylinder 6, upper flange 7 and the silicon rubber composite sheath 8 of the fire-retardant resistance of low-density.Be provided with ring 71 and upper flange outer shroud 72 in upper flange on upper flange, be provided with ring 11 and lower flange outer shroud 12 in lower flange on lower flange, in lower flange, the height of ring is higher than the lower flange outer shroud; In upper flange, the height of ring is higher than the upper flange outer shroud.In upper flange ring 71 with lower flange in, encircle 11 with interior glass fibre reinforced plastic cylinder 6, with outer glass fibre reinforced plastic cylinder 4, by organic Materials with High Strength, be cast in together with; Together with the upper flange outer shroud is cast in by organic Materials with High Strength with outer glass fibre reinforced plastic cylinder with the lower flange outer shroud.Reach interior glass fibre reinforced plastic cylinder inside and be filled with the damp insulating polymeric material 5 of the fire-retardant resistance of low-density between interior glass fibre reinforced plastic cylinder and outer glass fibre reinforced plastic cylinder, the glass fibre reinforced plastic cylinder surface binded has the compound umbrella cover 8 of silicon rubber outside.
