Specific embodiment
The present invention is further described in detail with reference to the accompanying drawings and embodiments.
The present invention is single in order to solve performance dimension existing for the arc-chutes or breaker of the prior art, i.e., is added by producing gas
Fast arc extinguishing provides one the deficiencies of can only selecting one with temperature resistant grade is enhanced by thermosetting material, can not carry out performance fusion, complementation
The breaker of kind arc-chutes and the arc-chutes, thermosetting material is effectively combined with gas exhausted material, and then play association
Same-action, i.e. thermosetting material and gas exhausted material respectively play the role of it is due except, also formed and had complementary functions, and then promoted and make
With the service life, and guarantee good interrupting performance.
As shown in Figure 1 and Figure 2, the arc-chutes 10 include several arc extinguishing grid pieces 11, flash barrier 12, and arc extinguishing grid pieces 11 are set
It sets between two flash barriers 12；Arc extinguishing grid pieces 11 form arrangement in the height direction, and are provided with and accommodate the progress of moving contact 20
The active chamber 101 of movement accelerates arc extinction and enhancing heatproof etc. to be provided simultaneously with arc-chutes 10 of the present invention
Grade sets gradually on the side wall 102 for accommodating the active chamber 101 that moving contact 20 is moved and produces gas plate 13, thermosetting bracket 14,
Thermosetting bracket 14 blocks between production gas plate 13 and moving contact 20.As shown in Figure 3, Figure 4, in the present embodiment, arc extinguishing grid pieces 11 are wrapped
The grid foot with spacing is included, active chamber 101 is mainly by the grid bottoms of the arc extinguishing grid pieces 11 arranged along short transverse at shape
At between the grid foot of all arc extinguishing grid pieces 11.Corresponding, the side wall 102 of the active chamber 101 is along height side
Opposite two planes or curved surface spatially formed to the grid foot inner side edge edge of the arc extinguishing grid pieces 11 of arrangement.In turn, base
In the side wall 102, produces gas plate 13 and be successively superposed on side wall 102 with thermosetting bracket 14.The thermosetting bracket 14
It is produced, and is blocked in producing between gas plate 13 and moving contact 20 using thermosetting material, then can avoid high temperature ablation, make to produce gas
The deformation of plate 13 and moving contact 20 are contacted with the formation of gas plate 13 is produced, and cause 20 clamping stagnation of moving contact.
Specifically, as shown in Figure 5, Figure 6, the cladding of thermosetting bracket 14 produces gas plate 13, offers air passing hole on thermosetting bracket 14
141, it produces gas plate 13 and is communicated by air passing hole 141 with active chamber 101, then produce the H of the generation of gas plate 132It can be from air passing hole 141
Into in active chamber 101, the pressure in arc-chutes 10 is improved, accelerates arc motion.In the present embodiment, the air passing hole
It 141 opens up for several transverse directions, the long hole of longitudinal arrangement.The air passing hole 141 of longitudinal arrangement corresponds to the arc extinguishing with certain altitude
Room 10 enables in arc-chutes 10 for accelerating the gas pressure of arc motion to reach whole uniform.The air passing hole laterally opened up
141 can cover the lateral length of entire active chamber 101 as much as possible, to add on entire lateral length to electric arc
Speed.
In order to facilitate assembly, while the part deformed by high temperature is set as little as possible, is guaranteed under high-temperature work environment
Job stability, in the present invention, thermosetting bracket 14 is using nail installation is exempted from, and specifically, the upper and lower ends of thermosetting bracket 14 are distinguished
Equipped with position-limit mechanism, thermosetting bracket 14 is installed on flash barrier 12 by position-limit mechanism, and forms longitudinal direction, and perpendicular to flash barrier
The limit in 12 directions.Thermosetting bracket 14 is set on flash barrier 12 by position-limit mechanism, is set by the structure of position-limit mechanism
Meter, can be realized longitudinal limit, and perpendicular to the limit in 12 direction of flash barrier, prevent thermosetting bracket 14 from longitudinal, vertical
Directly fall off on 12 direction of flash barrier.In the present embodiment, 14 upper and lower ends position-limit mechanism of thermosetting bracket is respectively the upper card of " L " type
Button 142, lower buckle 143, the upper buckle 142 of " L " type and lower 143 pairs of flash barriers 12 of buckle form clamping limit.After being installed in place,
The upper buckle 142 of " L " type, it is lower buckle 143 vertical plane flash barrier 12 outside formed necking, can be realized perpendicular to arc
The limit in 12 direction of plate；The upper buckle 142 of " L " type, it is lower buckle 143 lateral face flash barrier 12 upper lower edge formed clamping limit
Position, can be realized longitudinal limit.
In order to guarantee the installation stability of thermosetting bracket 14, the upper of flash barrier 12 transversely offers resigning breach 121, on
Buckle 142, which is assembled to, to be installed in resigning breach 121；The lower edge of flash barrier 12 is provided with step 122, for lower buckle 143
Form contact limit.It, can be by thermosetting bracket 14 by the clamping limit of resigning breach 121 and the contact limit of step 122
It is precisely fitted into position.The mounting means for simplifying thermosetting bracket 14 simultaneously, i.e., from thermosetting bracket 14 towards the side of moving contact 20
To being slidably inserted into.
Gas plate 13 is produced in order to body more closely protect, the direction of thermosetting bracket 14 towards moving contact 20 is provided with cladding wall 144,
Coat the end face that wall 144 covers flash barrier 12, produces gas plate 13, arc extinguishing grid pieces 11.Meanwhile cladding wall 144 also can be to thermosetting branch
Installation site of the frame 14 on flash barrier 12 is positioned, and 14 excessive slip of thermosetting bracket is prevented to be inserted into.
The side for producing gas plate 13 towards arc extinguishing grid pieces 11 is provided with grid slot 131, and the correspondence of arc extinguishing grid pieces 11 is installed in grid
In slot 131, adjacent arc extinguishing grid pieces 11 are separated by grid slot 131, prevent the grid foot of arc extinguishing grid pieces 11 by
During arc erosion, puncture between grid foot and influence arc voltage, improves the class of insulation between arc extinguishing grid pieces 11,
Improve arc extinction performance.And locked by screw 132 from outside, locking produces gas plate 13, guarantee the installation stability for producing gas plate 13, from
The screw 132 that outside is locked avoids high temperature from influencing deformation far from electric arc.
Based on the arc-chutes 10, the present invention also provides a kind of breakers for assembling the arc-chutes 10, such as Fig. 7, figure
8, shown in Fig. 9, including arc-chutes 10, moving contact 20, static contact 21, pedestal 22, in the present embodiment, static contact 21 is mounted on arc extinguishing
The lower section of room 10, one end of moving contact 20 are rotatably arranged on pedestal 22, and the other end is set in active chamber 101.In pedestal 22
221 inner wall of installation room of arc-chutes 10 is set, equipped with the spacing block set 222 opposite with thermosetting bracket 14, spacing block set 222 and heat
Clamped 14 contact of frame forms thermosetting bracket 14 in the direction towards moving contact 20 and limits.
Further, it is additionally provided with upper cover 23, after upper cover 23 is installed in place, forms contact limit from the position of upper buckle 142
The stability of thermosetting bracket 14 is reinforced in position.
Above-described embodiment is intended merely to illustrate the present invention, and is not used as limitation of the invention.As long as according to this hair
Bright technical spirit is changed above-described embodiment, modification etc. will all be fallen in the scope of the claims of the invention.
