Abstract
The invention discloses an 800kV outdoor rod-shaped post porcelain insulator. The 800kV outdoor rod-shaped post porcelain insulator comprises two porcelain insulator bodies and four metal fasteners, wherein two of the metal fasteners are arranged at the two ends of one porcelain insulator body respectively, the other two metal fasteners are arranged at the two ends of the other porcelain insulator body respectively, and every two adjacent metal fasteners are fixedly connected. The 800kV outdoor rod-shaped post porcelain insulator is characterized in that the porcelain insulator bodies comprise rod-shaped porcelain rod bodies and even numbers of array porcelain umbrella bodies which are arranged on the peripheries of the rod-shaped porcelain rod bodies; the even numbers of array porcelain umbrella bodies comprise a plurality of large-diameter porcelain umbrella bodies, and meanwhile two small-diameter porcelain umbrella bodies are arranged between every two adjacent large-diameter porcelain umbrella bodies in a spaced mode. The 800kV outdoor rod-shaped post porcelain insulator has the advantages that the distances S between umbrellas can be longer by the adoption of the even numbers of array porcelain umbrella bodies, the probability of a flashover path formed in the way that bridging happens to rainwater between every two adjacent large-diameter porcelain umbrella bodies is lowered, the structural mode that two elements are combined into an 800 kV outdoor rod-shaped post porcelain insulator is adopted, a larger insulation margin is obtained, and thus the 800kV outdoor rod-shaped post porcelain insulator achieves a more reliable external insulation and high-voltage resistance level under an abnormal state rain wetting environment or a humid environment.
Description
Technical field
the present invention relates to a kind of 800kV outdoor solid core post insulator, be mainly used in the electric equipments such as 800kV high pressure above power station bus or isolating switch.
Background technology
ceramic material pillar rod insulator is the necessary part of insulating supporting of the electric equipment electric conductor such as 800kV high pressure above power station bus or isolating switch, sized by the umbrella shape of international standard type porcelain insulator product, umbrella or equal diameter umbrella odd number array, be generally applicable to the term of reference environment of normality or standard.Existing 800kV outdoor solid core post insulator is generally combined by three elements or four elements simultaneously, but due to standard porcelain insulator umbrella shape and size limitation and multicomponent combination metal connecting piece causes insulation distance loss to cause insulator to tolerate wet flashover more or hygral shock voltage levvl hoisting power is limited, under level and vertical rainfall are greater than the inferior unconventional high humidity environment of 5mm and heavy showers environment, very easily there is trip phenomenon.
Summary of the invention
the present invention seeks to: not only structure is simple to provide one, and reduces the probability that rainwater forms flashover path, reduces metal fastenings quantity between porcelain insulator body, and improves the 800kV outdoor solid core post insulator of insulation margin.
technical scheme of the present invention is: a kind of 800kV outdoor solid core post insulator, comprise two porcelain insulator bodies, and be located at four metal fastenings at two porcelain insulator body two ends respectively, wherein adjacent two metal fastenings are fixedly connected with, described porcelain insulator body comprises the rod type porcelain body of rod, and be located at the even numbers array porcelain umbrella body of described rod type porcelain body of rod periphery, described even numbers array porcelain umbrella body comprises several major diameter porcelain umbrella bodies, is interval with two minor diameter porcelain umbrella bodies between adjacent major diameter porcelain umbrella body simultaneously.
as preferred technical scheme, height and the H1 of single porcelain insulator body and its two ends metal fastenings are 2311mm ± 50mm, and the height H of described 800kV outdoor solid core post insulator is 4628mm ± 50mm simultaneously.
as preferred technical scheme, described minor diameter porcelain umbrella body is 55 mm ± 20mm relative to the value p1 that stretches out of the described rod type porcelain body of rod, and described major diameter porcelain umbrella body is 95 mm ± 20mm relative to the value p2 that stretches out of the described rod type porcelain body of rod.
as preferred technical scheme, the umbrella spacing S of adjacent major diameter porcelain umbrella body is 132 mm ± 20mm.
as preferred technical scheme, described even numbers array porcelain umbrella body and the described rod type porcelain body of rod one-body molded.
advantage of the present invention is:
1. the present invention adopts even numbers array porcelain umbrella body to form space between some long spacing umbrellas, namely umbrella spacing S is increased, reduce rainwater bridge joint between two major diameter porcelain umbrella bodies and form the probability of flashover path, and take two element to be combined into 800kV outdoor solid core post insulator frame mode, compared with the 800kV outdoor solid core post insulator of three elements or four elements combinations in prior art, in it, insulation and external insulation space accounting in the product all increase, therefore larger insulation margin is obtained, 800kV outdoor solid core post insulator of the present invention is made to drench with rain abnormal or possess more reliable external insulation under wet environment, high pressure resistant level, can safe operation under unconventional high humidity environment and heavy showers environment,
2. the present invention comes alternative three elements or four elements combinations with two element, decrease metal fastenings quantity between porcelain insulator body, and the space shared by virgin metal securing member is replaced by porcelain insulator, thus obtain larger insulation margin, make invention 800kV outdoor solid core post insulator drench with rain abnormal or under wet environment, possess more reliable external insulation, high pressure resistant level.
