According to above the deficiencies in the prior art, the technical problem that the utility model mainly solves is: provide a kind of insulator strength height, insulation effect is good, highly low, easy for installation and the difficult aging outdoor bar-shaped porcelain insulator of interchange 220kV.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
The outdoor bar-shaped porcelain insulator of described interchange 220kV, comprise porcelain spare, porcelain spare upper end arranges upper flange, porcelain spare lower end arranges lower flange, porcelain spare is provided with a plurality of gamps and a plurality of umbellule, and gamp and umbellule are spaced, and the edge of gamp and umbellule and coupling part are no rib camber line structure, the porcelain insulator that porcelain spare, upper flange and lower flange are formed is the single-unit structure, and the insulator structure total height that porcelain spare, upper flange and lower flange are formed is 1800mm-2120mm.
The outdoor bar-shaped porcelain insulator of described interchange 220kV is single-unit porcelain element, and joint number is few, and under same requirement of mechanical strength, the porcelain insulator diameter is little, economical with materials.In addition, the utility model is guaranteeing under the creepage condition than distance, umbrella shape is designed to the open shape structure of size, this kind beveled structure is easier to moulding and the wind and rain self-cleaning property is good, wherein gamp and umbellule constitute the cluster parachute structure on the porcelain spare, the cluster parachute structure can adopt the different big umbellule alternating structure of diameter, also can adopt the identical umbrella structure of diameter.The brown glaze that the insulator surface last layer is smooth, shinny and hard, improved the machinery of product and electric property simultaneously upper flange and lower flange material all adopt spheroidal graphite cast-iron, processing rear surface hot galvanizing is handled, and has increased the decay resistance of flange.Compare the low 200～400mm of height of the product of two joint porcelain insulator elements compositions, reduced a pair of flange, installation difficulty and cost be corresponding reduction all.
Described porcelain spare is divided on the porcelain spare in main body, the porcelain spare main body three parts under the main body and porcelain spare from top to bottom successively, and the main body upper end connects upper flange on the porcelain spare, and the main body lower end connects lower flange under the porcelain spare, and main body is provided with a plurality of gamps and a plurality of umbellule in the porcelain spare.Strengthen anti-mechanical strength ability.
Main body is integral by cement glue and upper flange mucilage binding on the described porcelain spare, and main body is integral by cement glue and lower flange mucilage binding under the porcelain spare.Adopt cement glue to make porcelain spare and flange mucilage binding in aggregates, the reliability of reinforced insulation effectively prevents from wearing out.
The beneficial effect that the utility model has is:
The outdoor bar-shaped porcelain insulator of described interchange 220kV is single-unit porcelain element, and its product total height is 1800～2120mm, hangs down 200～400mm than two height that save the product of porcelain insulator elements composition, has reduced a pair of flange, and installation difficulty and cost be corresponding reduction all.The utility model product hangs down 200～400mm than the height of the product that two joint porcelain insulator elements are formed, and it is few to connect joint number, and under same requirement of mechanical strength, the porcelain insulator diameter is little, economical with materials.In addition, the utility model is guaranteeing under the creepage condition than distance, and umbrella shape is designed to the open shape structure of size, and this kind beveled structure is easier to moulding and the wind and rain self-cleaning property is good.
