Abstract
The invention provides an interlayer insulator mandril core for a converter valve tower. The mandril core comprises a mandril core body; threads are formed at one end of the mandril core body to form a mandril core thread rod; or threads are formed at the two ends of the mandril core body to form two mandril core thread rods. In addition, the mandril core also includes a metal connecting end connected with the mandril core thread rod; the metal connecting end includes a pull rod and a turnbuckle; a thread is formed at one end of the pull rod to form a pull rod thread rod; and the mandril core thread rod matches the turnbuckle and can be screwed into the turnbuckle from the other end of the turnbuckle. When the turnbuckle rotates, the length of the metal connecting end can be adjusted, thereby realizing fine tuning of the length of the interlayer insulator mandril core for a converter valve tower. In addition, the invention also discloses an interlayer insulator for a converter valve tower. According to the invention, when a converter valve is installed, fine tuning of the length of the interlayer insulator for a converter valve tower can be realized, so that forces exerted on all insulators for converter valve towers become uniform.
Description
Technical field
The invention belongs to high-voltage dc transmission electrical domain, sub and excellent particularly to a kind of converter valve tower layer insulation
Core.
Background technology
High voltage direct current transmission converter valve valve tower, its structure the most all uses suspension, flexible shockproof structure to design:
Being assembled by many layer insulation between each valve layer of valve tower, each layer insulation is solid by plain bolt
It is scheduled on upper and lower valve layer slot in frames steel, owing to the length of each layer insulation there are differences, insulator
Installing can be relatively difficult, the most typically in a disguised form regulates interlayer insulator by increase and decrease pad on frame base
Length, so that the sub-uniform force of each layer insulation between the valve layer after An Zhuaning, though the method is feasible, but peace
During dress relatively time-consuming arduously.To this end, the present invention proposes a kind of converter valve layer that can regulate length easily and fast
Between insulator.
Summary of the invention
The purpose of the present invention, is to provide a kind of sub and excellent core of converter valve tower layer insulation, this converter valve
Sub and the excellent core of tower layer insulation is easy to length adjustment and the installation of insulator between valve layer.
In order to reach above-mentioned purpose, the solution of the present invention is: converter valve tower layer insulation sub-rod core,
Including rod core body；It is characterized in that: one end of described rod core body is provided with screw thread, forms an excellent core screw thread
Bar；Or the two ends of rod core body are equipped with screw thread, form two excellent core threaded rods；Also include and rod core screw thread
The metal connection end that bar connects；Described metal connection end includes pull bar and flower basket bolt；The one of described pull bar
End also is provided with screw thread, forms pull rod screw bar；Rod core threaded rod and described flower basket bolt is suitable and from the gaily decorated basket
The other end screws in flower basket bolt；When rotating described flower basket bolt, it is possible to regulate described metal connection end
Length, is finely adjusted with the length to described converter valve tower layer insulation sub-rod core.
As further improved technical scheme of the present invention, the other end of pull bar is barrel nut structure.
For realizing above-mentioned technical purpose, the another kind of technical scheme that the present invention takes is: converter valve tower interlayer
Insulator, including rod core and the umbrella disk being enclosed within rod core；It is characterized in that: described rod core is above-mentioned converter valve
Valve tower layer insulation sub-rod core, described umbrella disk is enclosed within rod core body.
The pull rod screw rods and bars core threaded rod of the present invention screws in inside flower basket bolt, by rotating flower basket bolt
The length of metal connection end is adjusted, thus to converter valve tower layer insulation sub-rod core or the change of current
The length of valve valve tower layer insulation is finely adjusted.
In the present invention, the excellent core body of converter valve tower insulator rod core is identical with the plug of conventional insulators.This
In invention, the umbrella disk of converter valve tower insulator is identical with the umbrella disk of conventional insulators, and umbrella disk number is as required
Creep age distance determine, each umbrella disk shape both can be identical, it is also possible to is different.
In a word, in the present invention both can only sub-to layer insulation one end upper metal connection end use flower basket bolt,
Also the upper and lower metal connection end of insulator can be used flower basket bolt simultaneously；Can be to converter valve tower interlayer
The length of insulator rod core or converter valve tower layer insulation is finely adjusted；Can easily and fast right
The length of converter valve tower layer insulation is finely adjusted, it is simple to converter valve tower layer insulation is installed,
And make each converter valve uniform force of tower layer insulation between valve layer.
Accompanying drawing explanation
Fig. 1 is layer insulation position view in converter valve tower.
Fig. 2 is the converter valve schematic diagram of tower layer insulation that the present invention proposes.
In accompanying drawing, each parts labelling is as follows: 1-rod core body, 2-umbrella disk, 3-metal connection end, 4-rod core
Threaded rod, 5-pull bar, 6-flower basket bolt, 7-pull rod screw bar.
Below with reference to accompanying drawing, technical scheme is described in detail.
