Description
Technical field
The utility model relates to the insulation accessory technical field of UHV transmission line, relates in particular to a kind of intermediate connector of binodal DC compound insulator.
Background technology
In the UHV transmission line of ± 1100kv electric pressure, electric property to insulator has very high requirement, because extra high voltage direct current transmission line is in operation and has Electrostatic Absorption, arc current does not have situations such as zero crossing, cause requiring very harsh to the external insulation leakage distance of insulator, possesses sufficiently long external insulation leakage distance and will satisfy insulator, the length of ± 1100kV extra-high voltage direct-current insulator often reaches tens meters, as use the insulator of this length of single-unit, do the time spent in wind or other external force in the use, the gold utensil of insulator end bears very big moment of flexure stress, excessive moment of flexure stress can make the gold utensil distortion, thereby influences the useful life of insulator; In addition, the insulator of tens meters length is given the transportation of product and is installed and all brought many difficulties.
Binodal structure composite insulator can solve the long problem of bringing of single-unit insulator length, binodal structure composite insulator is about to long insulator and is divided into two short single-unit insulators, and then connect into the composite insulator of the length that meets the requirements by intermediate connector, install and transportation with convenient, in the binodal infrastructure product, the effect of intermediate connector is extremely important.The design of intermediate connector is unreasonable, and the mechanical strength of whole composite insulator and electric property just may be not up to standard.
Summary of the invention
Be to solve the problems referred to above of prior art, the utility model provides a kind of reasonable in design, can eliminate the intermediate connector of binodal DC compound insulator of the moment of flexure stress of insulator end gold utensil.
For achieving the above object, the intermediate connector of a kind of binodal DC compound insulator of the present utility model, comprise connector main body, the two ends of connector main body respectively are provided with one group of connector that is used for the gold utensil of connection insulator, every group of connector has structure detachable and the flexible connection gold utensil, and two groups of connectors leave the different slit of direction so that two gold utensils rotate in two planes that are not parallel to each other around the tie point of connector and gold utensil.
Wherein, every group of connector comprises two veneers parallel to each other, leave described slit between two veneers of every group of connector, each veneer is provided with jack, this intermediate connector also comprises two groups of bolt and nuts that are connected with the jack of two groups of connectors respectively, and bolt and nut is used for gold utensil is bolted in connector.
Wherein, veneer is orthogonal between two groups of connectors.
Wherein, the angle between the bolt of two groups of connectors is 90 °.
Wherein, connector main body is one-body molded.
The beneficial effects of the utility model are: the gold utensil that is connected in the connector at connector two ends turns, and two gold utensils do not rotate on same plane, eliminated the moment of flexure stress that masterpiece time spent insulator end gold utensil outside bears so effectively, strengthen the mechanical strength of composite insulator, ensured the long-term mechanical performance of using of composite insulator; Simultaneously, intermediate connector and two single-unit insulators removably connect, and make things convenient for transportation and the installation of binodal composite insulator.

Embodiment
For the purpose, technical scheme and the advantage that make utility model is clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.
The utility model provides a kind of gold utensil with the insulator end the detachable and movable intermediate connector that is connected, and intermediate connector is connected to become a binodal composite insulator with two single-unit insulators.The gold utensil that is connected in the connector two ends is rotatable, two gold utensils rotate on two planes respectively, these two planes are not parallel, like this no matter external force from which directive effect in composite insulator, the gold utensil of the insulator end of two single-units all turns, and when two planes at two gold utensils rotation places were 90 °, can eliminate the moment of flexure stress that gold utensil bears this moment to greatest extent, thereby reach the protection gold utensil, strengthen the purpose of the mechanical strength of binodal composite insulator; Simultaneously, the utility model and two single-unit insulators removably connect, and the binodal composite insulator can be divided into two single-unit insulators during transportation, and convenient transportation also can hang on the job location respectively with the single-unit insulator during installation and assemble, makes things convenient for work high above the ground.
Be illustrated in figure 1 as the connector main body 1 of a kind of preferred embodiment of the present utility model, the two ends of connector respectively are provided with one group of connector 11, every group of connector 11 comprises two veneers parallel to each other 12, every veneer 12 is provided with jack 13, jack 13 on two veneers 12 of same group of connector 11 in correspondence with each other, between two veneers 12 of same group of connector 11 slit is arranged, two groups of connectors veneer between slit direction difference.Described connector main body is one-body molded.See this connector main body 1 from four sides respectively, can see that four sides of connector main body 1 all are concave shape.The veneer 12 of two groups of connectors 11 is orthogonal so that be connected in the gold utensil of two single-unit insulator ends of intermediate connector of the present utility model can be respectively be that rotate on 90 ° plane at two angles.
