Abstract
The utility model relates to a strain insulator-string which is applicable in installation and fixation of insulated aerial cable with rated voltage of 10 KV or less, consisting of a strain insulating wire clamp and insulator. The strain insulating wire clamp is stringed with the insulator through the pull rod 4 of the strain insulating wire clamp and the big pull ring 5 of the insulator; and the central axle lines of the strain insulating wire clamp are concentric. As the strain insulating wire clamp is stringed with the insulator, the utility model is convenient and rapid in construction and installation, great in shock resistance and swing prevention, great in clamping of aerial cable as well as uneasy in wire sliding, energy saving and pleasant.
Description
The utility model relates to a kind of installation and fixture of aerial insulated cable, is that a kind of interchange volume voltage that is applicable to is installed and fixing insulation strain insulator-string at 10KV and following aerial insulated cable specifically.
Along with the development need of China's modernization industry and urban construction, domestic " urban network restructuring " work open up comprehensively in, the 10KV aerial insulated cable has been adopted in a large number for power utilization network in the city, has improved the reliability, the fail safe that supply electricity consumption greatly.At present, China 10KV overhead wire is the outstanding bottle that adopts 2 P-4.5 basically on terminal and disconnected link rod, add with pistol screw bolt-type strain clamp these old products are installed, mainly there is the volume heaviness, easily broken, line loss is big, install loaded down with trivial detailsly, be easy to generate zero resistance insulator, also will regularly clean filthy deposition.So bring many Djumahs tired to site operation, the existing development need of incompatibility, the needs of more not satisfied aerial insulated cable, the new material, new technology, the new product that must employing match with it.But the installation and the fixture of existing aerial insulated cable exist weak point: 1, the insulation strain clamp is together not supporting with insulator, brings many inconvenience to construction and installation, and existing installation shock resistance, anti-pendulosity are not strong.2, insulation strain clamp clamping aerial cable holding force intensity not enough, exist the slip problem in the construction.
Main purpose of the present utility model is to provide a kind of insulation strain clamp and insulator string, and quick, the shock resistance of construction install convenience and anti-pendulosity are strong together, the clamping aerial cable hold put forth effort strong, be difficult for slip insulation strain insulator-string energy-conservation, attractive in appearance.
To achieve these goals, the technical solution of the utility model is a kind of insulation strain insulator-string, it is made up of insulation strain clamp and insulator, and the insulation strain clamp is connected in series with the big draw ring 5 of insulator mutually with the pull bar 4 of insulator by the insulation strain clamp, and insulation strain clamp central axis is concentric; The insulation strain clamp is by plastics wedge core 1, cover plate 2, housing 3, pull bar 4 is formed, plastics wedge core 1 is to be made by the block-shaped identical insulating material in two sides, its outer surface is half cone-shaped, the inner surface semicircular in shape, plastics wedge core 1 is positioned at housing 3, housing 3 has an opening 8 vertically, the taper seat of the inner surface of housing 3 for matching with plastics wedge core 1 outer surface, its difference is a plastics wedge core 1, inner surface has pawl 7, plastics wedge core 1 central authorities have hole slot 9 vertically, and the opening 8 of housing 3 is provided with cover plate 2, and pull bar 4 is inserted in the back with housing 3 by two pin vertical direction on the pull bar 4 and flexibly connects; Insulator is made up of big draw ring 5, silicon rubber full skirt cover 6, insulating rod, and silicon rubber full skirt cover 6 is enclosed within on the insulating rod, and big draw ring 5 buries riveted joint with insulating rod pin cross.
Aforesaid plastics wedge core adopts high-strength engineering plastic, and pawl is the 1.5mm height.
The utility model is owing to adopted said structure, 1, the insulation strain clamp is connected in series together supporting with insulator, make construction and installation more convenient, quick, the flexible connection of adopting big draw ring of insulator and housing to form is to installing the pneumatic effect of having played damping, having resisted pendulum of aerial insulated cable.2, plastics wedge core adopts high-strength engineering plastic; It is that semicircle back of the body open type 4 half compresses that plastics wedge core central authorities have hole slot 9 vertically; Adopt the high reverse pawl of 1.5mm, the clamping aerial cable makes the contact-making surface of aerial cable clamping bigger, thereby holding of it put forth effort byer force, has overcome the problem of slip in the construction.3, insulator is made up of big draw ring 5, silicon rubber full skirt cover 6, insulating rod, and silicon rubber full skirt cover 6 is enclosed within on the insulating rod, and big draw ring 5 buries riveted joint with insulating rod pin cross.Strengthen tensile strength.Replaced heavy suspension type ceramics with the silicon rubber full skirt, not only made product attractive in appearance, the more important thing is to make volume-diminished, weight saving is difficult for fragmentation, and self-cleaning is good, and is non-maintaining.4, the utility model has used nonmagnetic substance to satisfy the shell structure requirement as housing cover, has solved the eddy current of closed-loop path, and caused magnetic hysteresis loss has played energy-conservation effect.5, metal bracelet plays the effect that connects cover plate and housing in structure, has also played the effect of beautiful decoration.
Below in conjunction with each accompanying drawing the utility model is described in further detail.
