The content of the invention
Therefore the technical problem to be solved in the present invention is especially to provide a kind of extinguisher and a kind of safe controller switching equipment, it
Be characterised by, avoid occur foreword describe in detail knotty problem simultaneously, improve distribution capacity.
Above-mentioned technical problem passes through a kind of extinguisher and a kind of mechanical and electrical safety distribution with according to extinguisher of the invention
Equipment is addressed.
There is switch contact and arc-chutes according to extinguisher of the invention, switch contact includes fixed contact and relative in itself
In the motion contact that it is moved.Additionally, the first end that extinguisher has guide rail and wire turn, guide rail is located in the region of arc-chutes, with
And its second end is located in cup area, wire turn is conductively connected with the second end of guide rail, wherein, wire turn is in electric arc from motion contact
Just it is powered after being transformed on guide rail.Wire turn has first paragraph herein, and it is arranged on by the side of switch contact, so as to by electric arc at it
Extruded towards arc-chutes direction after conversion.Additionally, wire turn has second segment, it is at least partially disposed in arc-chutes with safe controller switching equipment
Shell side wide between, so as to by electric arc after its conversion towards arc-chutes direction attract.
It is powered by wire turn, an electromagnetic force for squeezing electric arc towards arc-chutes direction is applied on electric arc, so as to there
Extinguish electric arc.In other words：It is it is applied electromagnetic force on electric arc that electric circle can be powered, it is therefore an objective in "on" position, that is,
After in the transferred arc to guide rail, electric arc can be promoted towards arc-chutes direction.Now the first paragraph of wire turn is by electric arc towards arc-chutes
Direction extrudes cup area, in other words：First paragraph applies magnetic repulsion power on electric arc.Conversely, wire turn is at least partially disposed in going out
Second segment between arc chamber and safe controller switching equipment shell side wide, then suction out electric arc towards arc-chutes direction from cup area, changes sentence
Talk about：Second segment has magnetic attachment to act on electric arc.In a word, bigger power is applied on electric arc based on this design, so as to
It is rapider to extinguish electric arc.Distribution capacity thus, it is possible to be obviously improved extinguisher.

The characteristics of the first on off state is, extinguisher 10 by fixed contact 13 and can motion of relative its motion touch
The switch contact 12 of the composition of point 14 is closed, so electric current I can flow through switch contact 12.Illustrate by multiple arrows in fig. ib
Represent correspondingly, electric current I by this by the current path 8 of extinguisher 10：Electric current I is connect by the input that safety is equipped with equipment
Head (not shown), fixed contact 13 is flowed to via magnet exciting coil 2, and, in the case where switch contact 12 is closed, by motion
Contact 14 flows to the out splice going splice 9 of safe controller switching equipment.In order to extinguish the electric arc 11 formed when switch contact 12 is opened (see figure
2B), extinguisher 10 also has an arc-chutes 20.So-called cup area 21 (being represented by dashed line) is in arc-chutes 20 and switch contact 12
Between.Additionally, extinguisher 10 also has guide rail 23, its first end 23-1 is arranged on the lower section of arc-chutes 20, and by its second end 23-

It is first if leaving fixed contact by moving contact 14 in the state of energization to move and open switch contact 12
Electric arc 11 first is formed between fixed contact 13 and motion contact 14, so keeping electric current flowing to be touched by switch by electric arc 11
Point 12.If motion contact 14 further moves from fixed contact 13, based on increasing, distance is continuous to improve arc voltage, until
Electric arc 11 is changed from motion contact 14, that is, is jumped on guide rail 23.More precisely, electric arc 11 jumps to the second of guide rail 23
On the 23-2 of end, it is arranged on below switch contact 12 in cup area 21.The electric arc 11 burnt between feeler 24 and guide rail 23,
The feeler 24 being conductively connected by guide rail 23 and below fixed contact 13 and with it, is touched via another with feeler 24 and fixation
The guide rail 26 that point 13 is conductively connected, towards the direction guiding of arc-chutes 20.Herein, arc-chutes 20 are designed as traditional arc-chutes,
It has many arc quenching plates 22 for being set up in parallel and being spaced.If electric arc 11 drives from cup area 21 towards this direction of arc-chutes 20,
Multiple points of electric arcs are then divided into when it is collided on arc quenching plate 22, they then each arc quenching plate 22 and another guide rail 26 it
Between burn.Based on point electric arc of multiple this circuit sequence series connection, so producing arc voltage high, this ultimately results in tear electricity
Thus arc 11 simultaneously extinguishes electric arc 11.
In order to be able to further improve the distribution capacity of extinguisher 10, electric arc 11 should be pushed away more quickly towards the direction of arc-chutes 20
It is dynamic, and thus extinguished more rapidly.Therefore, extinguisher 10 has wire turn 30, it is conductively connected with the second end 23-2 of guide rail 23,
And be just powered after electric arc 11 is transformed on guide rail 23 from motion contact 14.Herein, wire turn 30 has first paragraph 31, it constitute with
The end 23-2 of guide rail 23 second is conductively connected and is arranged on by the side of switch contact 12, to be changed from cup area 21 in electric arc 11
It is extruded towards the direction of arc-chutes 20 afterwards.The second segment 32 of wire turn 30 is connected on first paragraph 31, it is at least partially disposed in goes out
Between arc chamber 20 and safe controller switching equipment shell side 4 wide, it is therefore an objective to by it towards arc-chutes after electric arc 11 is changed from cup area 21
20 directions attract.
Because the sense of current opposite orientation of the sense of current and electric arc 11 in the first paragraph 31 of wire turn 30, in electric arc
The electromagnetic force of repulsion effect is produced on 11.Conversely, the sense of current in second segment 32 is determined parallel to the sense of current of electric arc 11
To thus causing the electromagnetic force of sucking action on electric arc 11.In a word, due to this design of wire turn 30, made on electric arc 11
Acted on into dual power, it forces electric arc 11 that the direction of arc-chutes 20 is more quickly gone to from cup area.Electricity is made by described
Arc 11 more quickly enters in arc-chutes 20, significantly improves the distribution capacity of extinguisher 10.
In addition the detail drawing corresponding with shown in 1B with Figure 1A of wire turn 30 is schematically illustrated in fig. 1 c.In order to view it is clear for the sake of,
There is no arc-chutes 20 in this view.The integral design herein of wire turn 30, but it is also possible to by wire turn 30 be designed as by
Multi-section is grouped into.Additionally, wire turn 30 can with or be designed as plane, it is that is, flat, or be designed as bending, make it and cup area
Spatial depiction in 21 is adapted.Herein it can for example be configured to sheet metal bending part, have the wire rod of varying cross-section shape into
Type part can also be configured to pliable part, such as twisted wire.As well as may be by wire turn 30, outstanding other second segments 32,
Not only it is arranged between arc-chutes 20 and shell side 4 wide in side, but it is wide with two shells to be arranged on arc-chutes 20 in both sides
Between each of side 4.Therefore, wire turn 30 must have two second segments 32, circuit is connected mutually or in series or in parallel for they.
Fig. 2A to 2C schematically illustrates extinguisher 10 the first embodiment in corresponding view, and it is in different from the first
Second on off state.Fig. 2 B still schematically illustrate the side view of extinguisher 10.Fig. 2A represents corresponding underside view.Fig. 2 C

The characteristics of second on off state is that the switch contact 12 of extinguisher 10 has been opened now.Now form electricity
Arc 11, it burns between fixed contact 13 and motion contact 14 first.At this moment, electric current I is continued on through by switch contact 12
Flowing.If motion contact 14 is moved further away from fixed contact 13, arc voltage further increases, until electric arc 11 is from fortune
Movable contact 13 is transformed on the second end 23-2 of guide rail 23.Represent that this electric arc 11 is converted and in guide rail 23 in fig. 2b
The second end 23-2 and feeler 24 between state.The current path 8 for still being schematically illustrated with multiple arrows, matches somebody with somebody from safety herein
The input adapter of electric equipment, feeler 24 is extended to by magnet exciting coil 2 and fixed contact 13, from there through the direction guiding rail of electric arc 11
23 the second end 23-2 extends, and further the wire turn 30 by being powered now extends to out splice going splice 9.In further arc extinguishing
During, electric arc 11 by towards the direction of arc-chutes 20 promote, and there first guide rail 23, each arc quenching plate 22 and another
Burnt between guide rail 26.Fig. 2A represents this state.
Fig. 2 C represent the current path of the wire turn 30 not being powered in the same time at two, wherein also illustrating at two
Not electric arc 11 in the same time.In order to show both different state/moment, electric arc is represented with mark 11-1 and 11-2 in figure.
Fig. 2 C represent electric arc 11-1 directly after transferred arc first：Now electric arc 11-1 is in feeler 24 and the end of guide rail 23 second
Between 23-2.In this case, current path 8 extends to the second end 23-2 via electric arc 11-1, and via with this second end
The wire turn 30 of 23-2 connections extends to out splice going splice 9.It is in cup area 21 therein at this moment in electric arc 11-1, by electricity
The sense of current of arc 11-1, with the sense of current orientation opposite each other in the first paragraph 31 of wire turn 30.Because the electricity of opposite orientation
Stream is repelled one another, and electromagnetic force F1 is thus applied on electric arc 11-1, and electric arc 11-1 is stopped up the extruding of 20 directions by it towards arc extinguishing.
At second moment slightly late shown in Fig. 2 C, electric arc 11 has been in the region of arc-chutes 20 (see Fig. 2 B), is
Without representing arc-chutes 20 in the view of Fig. 2 C for the sake of view is clear.In this case, current path 8 passes through another
Guide rail 26 and electric arc 11-2 extend to the first end 23-1 of guide rail 23, further extend to its second end 23-2 by guide rail 23, with
And via the wire turn 30 being connected with this second end 23-2 extend to out splice going splice 9 again.At this moment by the electric current of electric arc 11-2
Direction and the sense of current in the second segment 31-2 of wire turn 30, orientation parallel to each other.Because same direction current attracts each other, therefore
Apply electromagnetic force F2 on electric arc 11-2, electric arc 11-2 is stopped up the attraction of 20 directions or held it in arc-chutes 20 by it towards arc extinguishing,
Purpose is to prevent to be gone out from arc-chutes 20.
By this design, hence it is evident that power effect of the increase on electric arc 11, this power is acted on electric arc 11 towards arc-chutes 20
Direction is squeezed, and electric arc 11 is more quickly entered in arc-chutes 20, and thus reach and more quickly extinguish electric arc.Therefore it is aobvious
Write the distribution capacity for improving extinguisher capacitance simultaneously thus improving safe controller switching equipment.
Fig. 3 A and 3B schematically illustrate second embodiment of extinguisher 10.Herein, in the region of the second segment 32 of wire turn 30
One ferromagnetic component 35 of additional setting, it is used to strengthen electromagnetic force of the second segment 32 on electric arc 11-2.No and line
The ferromagnetic component 35 that circle 30 is conductively connected, is preferably arranged between arc-chutes 20 and side wide 4 inside wire turn 30.Enhancing the
Two section of 32 electromagnetic force on electric arc 11-2, especially when electric current is favourable less than 1000 ampere-hours, because in such case
Under the electromagnetic force that is produced on electric arc 11 by wire turn 30, be often not enough in electric arc 1 smoothly push-in arc-chutes 20 and to be maintained at
There.
In addition it is at least partially disposed between arc-chutes 20 and side wide 4 by by the second segment 32 of wire turn 30, is additionally provided
