Background technology
Fast development along with Chinese national economy; Power industry has also had significant progress, but the electric power breach still continues to increase, for satisfying growing need for electricity; For surge power is injected in economic development; Except building energetically the generating plant, must adopt high voltage, jumbo power transmission and transformation system, improve electric energy transmitting efficient.Therefore 500,000 and even 1,000,000 volts of high voltage AC and DC transmission lines of electricity constantly build up.
Meanwhile how to guarantee the problem that the safe operation of transmission line of electricity has become each scientific research department and power equipment manufacturing enterprise to solve.For reaching this purpose, in the design of power equipment and circuit, manufacture process, must carry out high-caliber detection, can safe and reliable operation with assurance equipment.Need set up high-level product detects and the research laboratory for this reason.High-tension laboratory is because its singularity must reach following standard:
1), has good shield effectiveness.Because the hyundai electronics industrial expansion, various wireless device interference sources are ubiquitous, and therefore when power transmission and transforming equipment was carried out partial discharge test, testing laboratory must have good shielding.
2), testing laboratory is because the monomer scale of construction is huge, general area is at 1200m
2More than, the clear space height is between 20-55m, so the noise of test specimen is tested and the interference of test echo is very serious, and something must be done to controls.
Because voltage was low, adopt two to overlap independently that system carries out usually: screen layer and sound absorbing layer were installed separately in the past, and screen layer adopts six shieldings of steel plate welding, and abatvoix is installed in the screen layer surface, and there is following problem in this way:
1. the shielding steel plate is extremely thin, burns easily during welding, is out of shape, and is uneven when large tracts of land is laid, and influences attractive in appearance.
2. high temperature destroys surface of steel plate anti-oxidation protection layer when welding, influences screen layer serviceable life.
3. welding job amount is big, and long construction period and cost are high.
4. welding produces a large amount of harmful gases, and the workmen is healthy in infringement.
5. a large amount of artificial welding job and work high above the ground can't guarantee welding quality and personal safety.
6. be suspended on the screen layer surface owing to abatvoix, its metal fixing is easy to generate point discharge, serious disturbing effect test result.
Summary of the invention
The utility model provides a kind of high-tension laboratory shield assembly with shielding and sound-absorbing double effects, so that overcome in existing shielding and the sound absorbing layer construction: welding deformation, protective seam destroy, and problems such as metal fixing point discharge reach shielding and sound-absorbing effect.
The utility model for solving the scheme that its technical matters adopted: the high-tension laboratory shield assembly with shielding and sound-absorbing double effects; It is characterized in that: comprise barricade and abatvoix at least; Described barricade has the polylith splicing, and the junction between the barricade splicing has 90
0The right angle crimp, 90
0Magnetic material layer between the right angle crimp; The first right angle crimp, magnetic material and the second right angle crimp are connected through set bolt; Make the first right angle crimp, magnetic material and the second right angle crimp be integrally formed the formula screen layer; Abatvoix is laid in and shields the barricade rear side, and abatvoix supports through supporting purlin 7.
Described magnetic material adopts elastic magnetic material.
Described barricade 90
0The right angle crimp adopts assembly unit punching contraposition.
The beneficial effect of the utility model is: because the junction between the barricade 5 has 90
0The right angle crimp, 90
03 layers of magnetic materials separately are connected with the second right angle crimp 9 the first right angle crimp 8, magnetic material 3 between the right angle crimp through set bolt 4, make the first right angle crimp 8, magnetic material 3 and the second right angle crimp 9 be integrally formed the formula screen layer; Screen layer adopts punching shielding steel plate; According to concrete shielding requirements and sound-absorbing effect, select corresponding perforate size and percentage of open area, barricade adopts elastic magnetic material transition, erection method to connect; Sound absorbing layer is installed in after the screen layer; Select material different and thickness as requested, adopt extra purlin to support, therefore not be used in metal fixing is installed on the screen layer.The attractive material that is laid in behind the screen layer absorbs, and the echoing in the huge space of testing laboratory is effectively controlled.When reaching shielding and attracting technical requirement, can shorten construction period (can adopt the ground surface large area that the mode of integral hoisting is installed), reduce investment, and construction accomplish after testing laboratory's internal shield surfacing attractive in appearance, the barricade protective seam is intact.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further:
Fig. 1 is the utility model example structure synoptic diagram.
Among the figure: 1. testing laboratory's inner high voltage strong interferers, 2. outdoor wireless electrical interference source, 3. magnetic material, 4. set bolt, 5. barricade, 6. abatvoix, 7. supporting purlin, the 8. first right angle crimp, the 9. second right angle crimp.
Embodiment
As shown in Figure 1, have the shielding and the high-tension laboratory shield assembly of sound-absorbing double effects, comprise barricade 5 and abatvoix 6 at least, the junction between the described barricade 5 is by having 90
