Abstract
The utility model relates to an electric vacuum element for low-voltage power distribution, in particular to an electric arc extinguish chamber contact, belonging to the technical field of electric appliances. The contact is formed by compounding a CuCr alloy piece and a T2Y anaerobic copper piece. An arc extinguish chamber manufactured by adopting the vacuum arc extinguish chamber contact has electric performance superior to that of an arc extinguish chamber manufactured by adopting a CuCr alloy contact; and the cost can be greatly lowered.
Description
Technical field
The utility model relates to the electron tube, particularly vacuum arc-extinguishing chamber contact of low pressure for distribution, belongs to technical field of electric appliances.
Background technology
The low pressure permanent magnet type vacuum circuit-breaker of up-to-date appearance, because its highly reliable, long-life excellent properties enjoys the market favor, one of technical characterstic that it attracts people's attention is, substitute traditional air blowout grid with vacuum interrupter, improved circuit breaker and closed ability and the number of times that closes with the disjunction short circuit current, and electric life is up to more than ten thousand times.
Vacuum interrupter cut-offs and closes the ability of closing short circuit current, except that the Mechanics of Machinery parameter that need are mated, depends primarily on the material and the magnetic field structure of arc control device contact.Low-voltage vacuum arc control device contact all adopts single CuCr alloy material to manufacture both at home and abroad at present, and loop resistance is bigger than normal, and Electric Field Distribution is desirable not enough, and price is more expensive, makes the circuit breaker cost increase, and has limited application.
The utility model content
The purpose of this utility model is, solves the deficiency that exists in the above-mentioned technology, provides that a kind of Electric Field Distribution is even, loop resistance is little, connecting-disconnecting function is strong to innovation, simple in structure, technology maturation, vacuum arc-extinguishing chamber contact with low cost.
The purpose of this utility model is achieved in that two kinds of compound manufacturing of different metal material that vacuum arc-extinguishing chamber contact is strong by connecting-disconnecting function and conduct electricity very well, and in technical solution of the present utility model, contact is by CuCr alloy sheet and T
2Y anaerobic copper sheet is composited.
The CuCr alloy sheet and the T of described contact
2Y anaerobic copper sheet has identical external diameter.
The arc control device that the arc control device that adopt the utility model to manufacture are manufactured than single CuCr alloy sheet contact, loop resistance is little, and is low in energy consumption, Electric Field Distribution is obviously improved, connecting-disconnecting function increases, and the consumption of CuCr material also obviously reduces, and the cost of vacuum interrupter is reduced significantly.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is that the contact that the utility model proposes is assemblied in the indoor partial sectional view of vacuum extinction.
Embodiment
Describe the structure of the vacuum arc-extinguishing chamber contact that the utility model proposes in detail below in conjunction with accompanying drawing.
Contrast Fig. 1, the moving guide rod 5 of vacuum interrupter 6 is drawn back under external force as can be seen, and the contact 3 in the vacuum interrupter 6 is by CuCr alloy sheet 2 and T
2Y anaerobic copper sheet 1 compound composition.It can also be seen that two contacts 3 are assemblied in respectively on moving conductive rod 5 and the static conductive rod 4, and two CuCr alloy sheets 2 are corresponding mutually in the axial direction.
In the present embodiment, the external diameter of contact 1 is φ 52mm, and the thickness of CuCr alloy sheet 2 is 3mm, T
2The thickness of Y anaerobic copper sheet 1 is 8mm, and these two kinds of different metal disks adopt soldering processes to be combined into one.The short circuit current pass of vacuum interrupter under the 400V rated voltage closed and cut-off verification experimental verification, and making capability reaches 143kA, and connecting-disconnecting function reaches 65kA.
The foregoing description has only been enumerated a kind of size of contact 3, all change contact 3 diameters, changes CuCr alloy sheet 2 and T
2The thickness proportion of Y anaerobic copper sheet 1 concerns the variation on the equidimension, all belongs to and is equal to replacement, all in the claimed scope of the utility model.
Claims (2)
1. vacuum arc-extinguishing chamber contact, it is characterized in that: contact (3) is by CuCr alloy sheet (2) and T
2Y anaerobic copper sheet (1) is composited.
2. vacuum arc-extinguishing chamber contact according to claim 1 is characterized in that: CuCr alloy sheet (2) and T
