Abstract
The invention discloses a direct-current disc type suspension bell-shaped porcelain composite insulator dedicated to 210kN. The direct-current disc type suspension bell-shaped porcelain composite insulator includes a steel cap, a porcelain umbrella plate, a groove and a steel pin, wherein the diameter of the insulator is 330mm, the creep distance of the insulator is 500mm, and the porcelain umbrella plate and the groove are comprehensively covered with a silicon sulfide rubber umbrella sleeve which is 6mm thick. Through forming the outer insulating component which is 6mm thick and formed by sulphuration on the surface of the insulator, the steep wave resistance of the direct-current disc type suspension bell-shaped porcelain composite insulator is greatly improved, the porcelain composite insulator can pass 2.85-time negative lightning impulse voltage check by an amplitude method; through the determination of an artificial pollution test, the disc type suspension bell-shaped porcelain composite insulator has good pollution resistance under the condition of IV-level pollution; under the conditions of the same salt density and dust density, the pollution flashover resistance of the disc type suspension bell-shaped porcelain composite insulator is at least 1.8 times that of a disc type suspension bell-shaped porcelain insulator.
Description
Technical field
The invention belongs to cap and pin insulator technical field, particularly relate to a kind of suspension type of dc disc shape bell shape porcelain composite insulator being exclusively used in 210kN.
Background technology
Current, many provinces and cities of China, when especially the meteorological condition such as sleet, snow melt occurs the transmission line of provinces and cities in the north in the winter time, the insulator string that there will be vertical suspension is slipped bridge joint phenomenon by ice, the dielectric strength of the insulator string be bridged significantly reduces, and very easily flashover fault occurs.
For avoiding insulator string to be slipped bridge joint by ice, the multiple directions of people to insulator technology are developed, and wherein, tremble ripple tolerance and the anti-pollution ability that improve insulator become a Main way in people's research.
Summary of the invention
The object of this invention is to provide a kind of suspension type of dc disc shape bell shape porcelain composite insulator being exclusively used in 210kN, tremble ripple tolerance and anti-pollution ability with what improve insulator.
In order to realize object of the present invention, the invention provides a kind of suspension type of dc disc shape bell shape porcelain composite insulator being exclusively used in 210kN, comprise: steel cap, porcelain umbrella disk, groove and steel pin, the dish footpath of described insulator is 330mm, the creepage distance of described insulator is 500mm, wherein, described porcelain umbrella disk and groove are enclosed with the thick sulphurated siliastic umbrella cover of 6mm comprehensively.
The present invention, compared with prior art, the external insulation parts of the thick sulfuration of 6 ㎜ are formed at insulator surface by optimization silicone rubber formulations and processing technology, increase substantially suspension type of dc disc shape bell shape porcelain composite insulator steep wave tolerance, can by the porcelain composite insulator of amplitude method by 2.85 times of negative polarity lightning impulse voltage examinations; Because high temperature silicone rubber formula is unique, technique is advanced, the sulphurated siliastic umbrella cover of 6 millimeters thick formed is determined through artificial pollution test, disc suspension bell shape porcelain composite insulator has good anti-pollution characteristic under the filth of IV level, close with under the close condition of ash at identical salt, the resistance to pollution flashover ability of disc suspension bell shape porcelain composite insulator is at least 1.8 times of disc suspension bell shape porcelain insulator.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure, 1-steel cap, 2-porcelain umbrella disk, 3-groove, 4-steel pin, 5-sulphurated siliastic umbrella cover.
Embodiment
In order to make object of the present invention, technical scheme and beneficial effect clearly understand, below in conjunction with embodiment, the present invention is further elaborated.Should be understood to specific embodiment described herein only in order to explain the present invention, be not limited to protection scope of the present invention.
As shown in Figure 1, the invention provides a kind of suspension type of dc disc shape bell shape porcelain composite insulator being exclusively used in 210kN, comprise: steel cap, porcelain umbrella disk, groove and steel pin, the dish footpath of described insulator is 330mm, the creepage distance of described insulator is 500mm, wherein, described porcelain umbrella disk and groove are enclosed with the thick sulphurated siliastic umbrella cover of 6mm comprehensively.
210kN suspension type of dc disc shape bell shape porcelain composite insulator is according to the definition of Q/GDW 167-2007 to insulator name of product, carry out technical thought expansion to innovate with product structure: based on traditional direct current standard disc suspension bell shape porcelain insulator, develop a kind of Novel DC disc suspension bell shape porcelain composite insulator being applicable to direct-current ultra high voltage transmission line, high filthy area.By standard suspension type of dc disc shape bell shape porcelain or glass insulator high-temperature silicon disulfide rubber, porcelain umbrella disk and groove special formulation high-temperature silicon disulfide rubber are wrapped up comprehensively, adopt the low-temp low-pressure technology vulcanizing mold of original creation molded, form the sulphurated siliastic umbrella cover of 6 millimeters thick.
Wherein, compound umbrella cover insulating material refers to and forms the external insulation parts of the thick sulfuration of 6 ㎜ by optimizing silicone rubber formulations and processing technology at insulator surface, increase substantially suspension type of dc disc shape bell shape porcelain composite insulator steep wave tolerance, can by the porcelain composite insulator of amplitude method by 2.85 times of negative polarity lightning impulse voltage examinations.
Because high temperature silicone rubber formula is unique, technique is advanced, the sulphurated siliastic umbrella cover of 6 millimeters thick formed is determined through artificial pollution test, disc suspension bell shape porcelain composite insulator has good anti-pollution characteristic under the filth of IV level, close with under the close condition of ash at identical salt, the resistance to pollution flashover ability of disc suspension bell shape porcelain composite insulator is at least 1.8 times of disc suspension bell shape porcelain insulator.
Product provided by the invention, meets GB/T19443-2004 " nominal voltage is higher than the overhead transmission line insulator-direct current system porcelain of 1000V or glass insulation sub-element-definition, test method and acceptance criteria " requirement.Room temperature vulcanized silicone rubber used, sealing compound, related request by DL/T 627 " Prospect on RTV of Solidified Silicon Rubber in Normal Temperature for Insulator " standard.Suspension type of dc disc shape bell shape porcelain composite insulator of the present invention, meet Q/GDW167-2007 " direct current system dish type porcelain or glass compound full skirt insulator element ", " nominal voltage is higher than 1000V overhead transmission line composite insulator-definition for GB/T19519-2004, test method and acceptance criteria " and GB/T 1001.1-2003 " nominal voltage is higher than the direct current overhead transmission line composite insulator-definition of 1000V, test method and acceptance criteria ", the related request of DL/T-2006 " nominal voltage uses directive/guide part 1 higher than 1000V overhead transmission line insulator: direct current system porcelain or glass insulator " DL/T810-2012 " ± 500kV and above direct current composite rod insulator technical conditions " etc.
The present invention, except meeting above-mentioned requirements, also reaches following requirement:
1. impulse breakdown resistance test in air after poach, meets the requirement of " GB/T20642-2006 " standard, according to the porcelain composite insulator of amplitude method by 2.85 times of negative polarity lightning impulse voltage steep waves examinations;
