Abstract

The utility model provides a 10kv tensioning and insulating double-head pull ring which comprises an upper pull ring and a lower pull ring, wherein the upper pull ring and the lower pull ring are connected with each other by means of sheathing and buckling, and the two rings are not contacted with each other; the middle of the upper pull ring and the lower pull ring is externally provided with an insulating body which simultaneously separates the two rings from each other; and two heads of the upper pull ring and the lower pull ring are outwards exposed. The 10kv tensioning and insulating double-head pull ring is characterized in that the upper pull ring and the lower pull ring are welded by a U-shaped bent ring and an H-shaped iron plate which are made from hot galvanized round steels; the insulating body is cylindrical; and the outer wall of the cylindrical insulating body is provided with a resin surface layer and a V-shaped convex rib. For the pull ring, the force bearing area is large by adopting the H-shaped iron plate, the mutual contact can be avoided due to a concave part, the pull ring is cleaner after being poured by rain since the resin surface layer is durable and good in insulating effect, the service life is as long as more than 20 years, and the wall of the convex rib is thin and the convex corner of the convex rib is sharp so as to be similar to be arrester-shaped, so that the material is saved, the appearance is attractive, and the electric shock resistance is strong.

Description

10kV tension insulation double end draw ring

Technical field

The utility model relates to the connection draw ring of electric pole tension, particularly relates to a kind of 10KV tension insulation double end draw ring, belongs to the electric power facility field.

Background technology

The electric pole that is positioned on 10KV circuit corner must have printed line at angle bar cross-arm place with steel strand be embedded in underground piece stone or the cement prefab tension, to guarantee the balance of circuit, if circuit is loosening, lead on the 10KV power transmission sequence tower will make printed line charged, will cause electric shock accidents in case human body hits charged printed line.For fear of the generation of accident, prior art generally connects the insulator that porcelain insulator or steel inner core and outer wall are made with elastomeric material in backguy, though porcelain insulator low price breaks easily.And the insulator that steel inner core and outer wall are made with elastomeric material is stupid because of structured soil, and the dirty reason such as bad of outside resistant is not used in a large number, and the printed line of present most of 10KV circuit is in the unprotect state.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, and a kind of 10KV of being applicable to electric pole tension is provided, and ability to bear reaches 9 tons of pulling force, satisfies the power equipment safety requirement, and the good 10KV tension insulation double end draw ring of clean surfaces ability.

The technical scheme of the utility model 10KV tension insulation double end draw ring is: comprise draw ring and following draw ring, last draw ring is connected with the mutual hitch of following draw ring, but two rings do not contact, outside the middle part of upper and lower draw ring, isolator is arranged, isolator separates two rings simultaneously, expose at two of upper and lower draw ring, it is characterized in that the described draw ring of going up comprises curved ring of U font and the H shape iron plate welding fabrication that the galvanizing round steel is made with following draw ring, described isolator is a cylindrical insulator, and the outer wall of cylindrical insulator has the convex tendon of resin surface layer and V font.

The utility model discloses a kind of 10KV tension insulation double end draw ring, comprise, following two draw rings and isolator, main feature is that every draw ring has comprised the curved ring of U font that the galvanizing round steel is made, opening head welded H shape iron plate at the curved ring of U font, on, following two draw ring hitch connect, and angle staggers, and does not contact mutually, so between two draw rings and the outside, junction all separate and surround by isolator, particularly between two draw rings, to bear the compression of 9 tons of pulling force, therefore, adopt H shape iron plate lifting surface area big, recess is avoided again contacting with each other, add that resin surface layer is durable, insulation effect is good, and rainwater one drenches cleaner, long service life, can guarantee to use more than 20 years, and the convex tendon wall approaches the salient angle point, and similar Zinc-Oxide Arrester external form is so material is economized, beautiful outline form, the protection against electric shock performance is strong.

The utility model 10KV tension insulation double end draw ring, described galvanizing round steel is the A3 steel, the round steel diameter of the curved ring of U font in the upper and lower draw ring

Be 14mm, the galvanizing round steel of 14mm has been arranged, ability to bear is good, and intensity guarantees.The outside of described resin surface layer scribbles the special grand self-cleaning layer of fluorine.The special grand self-cleaning layer of fluorine has been arranged, and it is filthy especially to be difficult for knot on the surface of V font convex tendon.

The specific embodiment

The utility model relates to 10KV tension insulation double end draw ring, as Fig. 1-shown in Figure 4, comprise draw ring and following draw ring, last draw ring is connected with the mutual hitch of following draw ring, but two rings do not contact, last, outside the middle part of following draw ring isolator is arranged, isolator separates two rings simultaneously, on, following draw ring 1, expose at two of 2, it is characterized in that the described draw ring 1 of going up comprises the curved ring 11 of U font that the galvanizing round steel is made with following draw ring 2,21 and H

shape iron plate

12,22 welding fabrications, described isolator is a cylindrical insulator 3, and the outer wall of cylindrical insulator 3 has the convex tendon 31 of resin surface layer 32 and V font.Comprise, following two draw rings 1,2 and isolator 3, main feature is that every draw ring has comprised the curved ring 11 of U font that the galvanizing round steel is made, 21, opening head welded H shape iron plate 12 at the curved ring of U font, 22, on, following two draw rings 1,2 hitch connect, angle staggers, do not contact mutually, thus between two draw rings and the outside, junction all separate and surround by isolator 3, particularly between two draw rings, to bear the compression of 9 tons of pulling force, therefore, adopt H

shape iron plate
