Abstract
The utility model belongs to the technical field of power transmission and transformation apparatuses, particularly relates to a double-umbrella stain-resistant discoid suspension type glass insulator. The task of the utility model is to provide a double-umbrella stain-resistant discoid suspension type glass insulator capable of preventing the rainwater at the top of an upper umbrella of a glass member of the insulator from permeating towards an inner side at the bottom of the upper umbrella of the glass member of the insulator, aiming at the disadvantage that the rainwater at the top of the upper umbrella of the glass member of a conventional double-umbrella discoid glass insulator can permeate towards the inner side at the bottom of the upper umbrella of the glass member of the insulator. The double-umbrella stain-resistant discoid suspension type glass insulator comprises an iron cap, a glass piece and a steel leg; the glass piece is in a double-umbrella-shaped structure; an upper umbrella and a lower umbrella are arranged on the glass piece; the upper umbrella is discoid; the surface of the upper umbrella is streamlined; a water dripping ring is arranged on the edge of the bottom of the upper umbrella; the lower umbrella is inverted bowl-shaped; the outer side of the lower umbrella is a convex cambered surface; the inner side of the lower umbrella is a concave cambered surface; the diameter of the upper umbrella of the glass member is bigger than that of the lower umbrella; and an annular groove is arranged at the top of the inner side of the lower umbrella of the glass piece.
Description
Technical field
The utility model belongs to electric power defeated, power transformation equipment technical field, particularly a kind of pair of umbrella anti-pollution type disc suspension glass insulator.
Background technology
The safety of grid power transmission is the critical problem of transmission of electricity, and the key factor of influence transmission of electricity safety is a caused pollution flashover after the insulator contamination deposit makes moist.According to incompletely statistics, the rate of failure that China causes because of pollution flashover has caused tremendous loss up to more than 70% to economic society.According to pollution flashover mechanism characteristics, the approach that solves pollution flashover is to improve the insulator dielectric level, in order to improve the resistant insulation level of insulator, since nearly half a century, people have taked the increase creepage distance, be coated with water-repellent agent on its surface, improve contour structures design or the like measure, though obtained certain effect, but distance expection practical function hope preferably differs greatly, up to date two, 30 years, by the continuous accumulation of operating experience, people have designed a kind of pair of umbrella plate shape glass insulator, on the glass workpiece of this glass insulator adopts, following two beveled structures, last umbrella is big, subumbrella is little, and last umbrella surface is streamlined, be easy to rainwater and natural wind the filth of upper surface is eliminated, this glass insulator has certain resistant insulation effect; But in actual use, it is found that the rainwater at existing pair of umbrella plate shape glass insulator umbrella top on rainy day insulator glass spare can the umbrella bottom inside permeate on insulator glass spare, and cause the insulation resistance of insulator to descend.
Summary of the invention
Task of the present utility model is can umbrella bottom inside infiltration on insulator glass spare at the rainwater at existing pair of umbrella plate shape glass insulator umbrella top on rainy day insulator glass spare, and the weak point that the insulation resistance that causes insulator descends provides a kind of two umbrella anti-pollution type disc suspension glass insulators that stop rainwater umbrella bottom inside infiltration on insulator glass spare at umbrella top on the insulator glass spare.
The technical solution adopted in the utility model is finished in the following way: a kind of pair of umbrella anti-pollution type disc suspension glass insulator, it comprises chapeau de fer, glass workpiece and steel pin, glass workpiece is two beveled structures, be provided with umbrella and subumbrella on the glass workpiece, last umbrella is in the form of annular discs, and last umbrella surface is streamlined, the edge of last umbrella bottom is provided with a drip loop, it is inverted bowl-shape that subumbrella is, and the outside of subumbrella is a convex globoidal, and the inboard of subumbrella is a cancave cambered surface.
In above-mentioned pair of umbrella anti-pollution type disc suspension glass insulator, the last umbrella diameter of glass workpiece is greater than the subumbrella diameter.
In above-mentioned pair of umbrella anti-pollution type disc suspension glass insulator, be provided with cannelure at the top of the subumbrella inboard of glass workpiece.
The utility model is compared with existing pair of umbrella plate shape glass insulator, has following characteristics:
1, because the last umbrella surface of glass workpiece of the present utility model is streamlined, so be easy to the filth removing of rainwater and natural wind with the glass insulator upper surface.
2, because the edge of the last umbrella bottom of glass workpiece of the present utility model is provided with a drip loop, so when rainwater flows into this drip loop, can form the globule and downward drippage, stop further umbrella bottom inside infiltration on insulator of humidity, guaranteed enough effective creepage distances.
3, because the top of the subumbrella inboard of glass workpiece of the present utility model is provided with cannelure, very easily form spiral air flow when distinguished and admirable during through this place, dunghill is blown away, form good self-cleaning effect.
The structure that the utility model adopted, can remove the hidden danger that forms pollution flashover effectively---cause insulation resistance sharply to descend because of dunghill makes moist, reduced the probability of pollution flashover effectively.
