Description
Technical field
The utility model belongs to high-voltage dc transmission electrical domain, particularly a kind of converter valve tower layer insulation and excellent core.
Background technology
High voltage direct current transmission converter valve valve tower, its structure substantially all adopts suspension type, flexible shockproof structure design: assembled by many layer insulation between each valve layer of valve tower, each layer insulation is fixed on by plain bolt, on lower valve layer slot in frames steel, because the length of each layer insulation there are differences, insulator is installed can be more difficult, the general length by increasing and decreasing insulator between pad covert regulating course on frame base at present, thus make the sub-uniform force of each layer insulation between the valve layer after installing, though the method is feasible, but compare when installing and waste time and energy.For this reason, the utility model proposes a kind of converter valve layer insulation that can regulate length easily and fast.
Utility model content
The purpose of this utility model, be to provide a kind of converter valve tower layer insulation and excellent core, this converter valve tower layer insulation and excellent core are convenient to length adjustment and the installation of insulator between valve layer.
In order to reach above-mentioned purpose, solution of the present utility model is: the excellent core of converter valve tower layer insulation, comprises excellent core body; It is characterized in that: one end of described excellent core body is provided with screw thread, form an excellent core threaded rod; Or the two ends of excellent core body are equipped with screw thread, form two excellent core threaded rods; Also comprise the metal connection end be connected with excellent core threaded rod; Described metal connection end comprises pull bar and flower basket bolt; One end of described pull bar is also provided with screw thread, forms pull rod screw bar; Rod core threaded rod and described flower basket bolt suitable and screw in flower basket bolt from the other end of the gaily decorated basket; When rotating described flower basket bolt, the length of described metal connection end can be regulated, to finely tune the length of the excellent core of described converter valve tower layer insulation.
As the technical scheme that the utility model improves further, the other end of pull bar is barrel nut structure.
For realizing above-mentioned technical purpose, the another kind of technical scheme that the utility model is taked is: converter valve tower layer insulation, comprises excellent core and is enclosed within the umbrella disk on excellent core; It is characterized in that: described excellent core is the above-mentioned excellent core of converter valve tower layer insulation, and described umbrella disk is enclosed within excellent core body.
It is inner that pull rod screw rods and bars core threaded rod of the present utility model screws in flower basket bolt, regulate by rotating the length of flower basket bolt to metal connection end, thus the length of the converter valve tower layer insulation excellent core of son or converter valve tower layer insulation is finely tuned.
In the utility model, the excellent core body of converter valve tower insulator rod core is identical with the plug of conventional insulators.In the utility model, the umbrella disk of converter valve tower insulator is identical with the umbrella disk of conventional insulators, and umbrella disk number creepage distance is as required determined, each umbrella disk shape both can be identical, also can be different.
In a word, in the utility model, both only flower basket bolt can be used to the upper metal connection end of the sub-one end of layer insulation, also flower basket bolt can be used to the upper and lower metal connection end of insulator simultaneously; Can finely tune the length of the converter valve tower layer insulation excellent core of son or converter valve tower layer insulation; Can finely tune the length of converter valve tower layer insulation easily and fast, be convenient to converter valve tower layer insulation and install, and make the sub-uniform force of each converter valve tower layer insulation between valve layer.
