Specific implementation mode
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Shown in a and Fig. 2 b as shown in Figure 1, Figure 2, arc-control device provided by the invention, including grid made of side plate 1, isolation material
Grid 23, protective plate 4 and run-on tab component 5 made of piece 1, metal material；Side plate 1 can be side as shown in Figure 1
The rectangular shape of opening, grid 1 are connect with 1 inner wall of side plate, grid 1 include at least spaced partition board 22, adjacent two
Cavity is formed between a partition board 22, grid 23 is located in the space of two grid 1 formation, the limiting device on 23 head of grid
32 are located in one 2 card slot 23 of grid, and protective plate 4 is located inside side plate 1, the top of grid 1 and grid 23, run-on tab component 5
Inside side plate 1,23 both ends of grid 1 and grid.
As shown in figure 3, grid 1 is arranged in order inside side plate 1, it is Nian Jie with 1 inner wall of side plate by high-temperature plastic.It is adjacent
Cavity can be formed among two grid 1, grid 23 is packed into cavity, protective plate 4 is packed into first limit of the grid 1 with side plate 1
Between the platform 12 of position, it is respectively packed into a run-on tab component 5 on the outside of one 2 both ends of grid, the installation on side plate 1 is connected to by fastener
Hole can form the arc-control device of the present invention.
As shown in figures 4 a and 4b, the second limiting stand 11 and limitation protective plate 4 of restricted grid 1 inside side plate 1
First limiting stand 12；Second limiting stand 11 has slope, angular range 120 ° -170 ° angled with 1 inner wall of side plate.
1 two sides of side plate have primary and secondary buckle, 1 four jiaos of side plate to have connection through-hole；1 material of side plate can be SMC, DMC, PF, ureaformaldehyde modeling
The combination of one or more of material.
As shown in Fig. 5 a- Fig. 5 c, the side of grid 1 is tablet 21, is contacted with side plate 1 that the other side is partition board 22；Grid
It opens there are two card slot 23 on one 2 tops；Grid 1 is made of insulating materials, preferably ceramic.Deformed in one 2 forming process of grid it is small,
It especially reduces traditional U-shaped ceramics grid to dehisce excessive phenomenon, greatly reduces poor fit when between being packed into two side plates
And phenomenon of rupture.In order to reduce the initial resistance that electric arc enters arc-control device, need to note in traditional U-shaped ceramics grid assembling process
Two neighboring grid notch of anticipating is staggered, and production efficiency is relatively low；Using grid 1, due to the self structure of side plate 1 and grid 1
Limitation, notch can be staggered automatically when assembly, can prevent loading error substantially, greatly improve production efficiency.
Grid 23 can be tablet or U-shape.As shown in figures 6 a and 6b, the preferred grid 23 of the present embodiment is U-shaped；
The limiting device 32 to match with card slot 23 is arranged at 23 top of grid；It opens there are two notch 31 23 lower part of grid；31 shape of notch
Can be the combination of one or more of triangle, semicircle, arc, preferably triangle；Notch 31 is biased in grid 23 respectively
Heart line both sides, two notches 31 are mutually staggered；23 material of grid can be copper plated steel, nickel-clad steel plate, galvanized steel plain sheet, fine copper
Plate etc..Grid 23 can prevent the case where tablet grid multistage arc portions advance, part retreats during arc extinguishing, thus can
Improve electric arc movement speed；Notch 31 can form the magnetic flux of magnetic circuit distortion in grid lower part, make to generate to attract to electric arc
With more conducively electric arc enters arc-control device；Notch 31 biases, and notch staggers successively when installation, it is possible to reduce electric arc is initially encountered
The quantity of grid, to reduce the initial resistance into arc-control device.Classic flat-plate grid, grid notch person's electric arc placed in the middle enter
Initial resistance is larger when arc-control device, and grid notch biasing person needs to pay attention to adjacent grid when installing and staggers successively, production efficiency
It is relatively low；Grid 23 using the present invention keeps 23 direction of all grid to be unanimously inserted into grid 1 i.e. in practical set
Can, limiting device 32 is caught in the card slot 23 of grid 1, since 23 self structure of grid institute jagged 31 can be staggered automatically, can drop
Low loading error rate improves production efficiency.
As shown in figs. 7 a and 7b, run-on tab component 5 includes the big run-on tab 51 connected by connector 53 and small striking
Plate 52, big run-on tab 51 are in contact with the inner wall of side plate 1；Big run-on tab 51, small run-on tab 52 be metal conductive materials, preferably pure
Copper coin.
When practical arc extinguishing, electric arc is led to electric arc inside arc-control device by run-on tab component 5, electric arc first with grid
Electric arc is divided into the short arc of multi-stage series by 23 contacts, grid 23, and arc extinguishing is carried out using cathode and anode drop.Electric arc is in grid
23 surface of piece is moved to 4 direction of protective plate, if electric arc does not extinguish yet when reaching grid 1, electric arc will be close with grid 1
Contact carries out the secondary extinguishing of electric arc using the cooling of grid 1 with surface recombination effect.Protective plate 4 can reduce arc extinguishing mistake
The noise generated in journey, while outside can be reduced to the pollution inside arc-control device, reduce contact steam in contact fragmentation procedure
Diffusion into air.
For tradition all using the arc-control device of ceramic grid, The present invention reduces arc-control device quality, reduce relatively
Voltage reduces cost, reduces failure rate；Tradition relatively all using the arc-control device of metal grid, present invention decreases
Arc-control device volume improves frequent arc extinguishing ability, thus the advantages of had both the two, the shortcomings that both overcoming.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that those skilled in the art without
It needs creative work according to the present invention can conceive and makes many modifications and variations.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical solution, all should be in the protection domain being defined in the patent claims.
