Convex shoulder 40 keeps interlocking.
As shown in figure ia, contact board mount 36 is maintained at its on-position by ratchet 41 against the power of switch spring 42
In, in the on-position contact plate 15 from keep convex shoulder 40 lift and contact 17 is abutted under the pressure of spring 38,18,
On 22, to make line protection switch be maintained in its on-state.
In the trouble-free normal operation of the line protection switch according to the present invention, electric current passes through electromagnetism from binding post 16
The coil 11 of electrical apparatus release 10 flow to the first contact 17, the second contact 18 is flow to by contact plate 15 and passes through primary current path 19
Wire element flow to another binding post 20.Although contact 22 is closed, it is practically without electric current and flows through with the He of thermal trip 23
Open circuit and the primary current path of trip assembley therefor 24, because primary current path 21 is by the short circuit of primary current path 19.
If because failure is in the electrical appliance side generation overcurrent of power network, magnetictrip 10 is responded and armature 12 makes
Striker 14 hits contact plate 15, is represented as shown in fig. 2 and in fig. 2b by empty position 43.Thus, connect
Touch panel 15 surrounds the pivot axis pivot formed by contact 17,22 against the power of spring 38 so that contact plate 15 it is corresponding right
Answer contact to be lifted from contact 18, thus open contact 18, and first and the 3rd contact 17,22 remain closed.In the illustrated case
Represented as spring 38 with compression spring, the compression spring is further compressed by the pivoting action of contact plate 15, thus makes to connect
Touch panel 15 keeps rabbeting with the power of increase and contact 17 and 22.In addition, overcurrent also flows through the coil 11 of magnetictrip 10, connect

If manually switch 33 is taken to after the Failure elimination in power network in its on-position, switch lever again
During 46 return to position shown in figure ia from position shown in Figure 4 A along clockwise movement, thus spine is made by the motion
Pawl 41 also from it during shown open position moves to on-position shown in figure ia again in Figure 4 A, wherein, the spine
Pawl again with ratchet spring rabbet, the ratchet spring make herein ratchet 41 in the counterclockwise direction so pivot so that the ratchet with
Retaining pin 45 on contact board mount 36 is formed keeps interlocking in other words.When switch lever 46 and ratchet 41 continue to move, hinge
The ratchet 41 being connected on rotatable switch lever 46 makes the contact board mount 36 rabbeted by its retaining pin 45 and ratchet 41 again
Move in its closure or on-position.Here, switch spring 42 is tensioned.
If being transformed into it by thermal trip 23 due to overcurrent according to the line protection switch of the present invention disconnects shape
In state, then the line protection switch can at once be reclosed after failure is eliminated without other measures.For excessively electric
Stream is only applied to the situation on line protection switch in short time, because the line protection switch for example connected below has responded to
And the fault zone of already off power network, armature 12 also falls after rise and spring 38 can take contact plate again to institute in figure ia
In the on-position shown.
But in the event of short circuit, then magnetictrip 10 is responded and interrupted first as in the case of overcurrent
Primary current path 19, thus short circuit current flow flow through primary current path.From unlike the situation of overcurrent, now open circuit and thread off
Component 24 is responded, and the open circuit and trip assembley therefor actually simultaneously switch off primary current path and make switch lock by means of its striker 29
30 lever 48 being pivotally supported is pivoted counterclockwise, as shown in Figure 3 A, as shown in.Lever 48 is in its supporting member 49
Upper to have projection 50, the projection, which contacts convex portion 51 with the second of ratchet 41 and produced in pivoting action, to be rabbeted and makes the ratchet inverse
Ratchet spring power along pivot clockwise so that the retaining pin 45 of the ratchet release contact board mount 36, be then brought into plate branch
Frame 36 be switched on and off as in overcurrent situations spring 42 move to its in Figure 4 A shown in open position in.Herein, by
In interruption primary current path and primary current path, currentless contact 17,22 is opened, without occurring electric arc.
Here, open circuit and trip assembley therefor 24 are suitably made up of Fuse assembly, the fusible link of the Fuse assembly and/or holding
Silk makes contact plug 29 be maintained at the institute in Figure 1A, 2A and 4A of the contact plug against dropout spring force in a manner not shown in detail
In the ready position shown.Once the fusible link of Fuse assembly and possible holding silk are fused due to big short circuit current flow, then set
Put the dropout spring in Fuse assembly to move in its trip positions with making the impact type of striker 29, thus the striker as above institute
Manipulate switch lock 30 with stating.
Open circuit and trip assembley therefor 24 must be replaced after line protection switch is threaded off in a short-circuit situation.It is this such as attached
As dotted line is shown in figure, removable cover 52 or like are set on the housing 37 of line protection switch.Cover 52 outstanding
It is provided with shaft-like extension 53, and the extension has hook 54 on its free end, and hook interlocking is in open circuit and trip assembley therefor
Below 24 or below.If cover 52 takes upwards in the accompanying drawings after being released by suitable immobilising device (not shown) if necessary
Get off, then open circuit and trip assembley therefor 24 are removed upwards together simultaneously and pulled out between contact element 25,26.Therefore,
Open circuit and trip assembley therefor 24 can take out from the line protection switch according to the present invention in the case of without instrument and with
One new open circuit and trip assembley therefor are replaced.Because switch lever 46 prevents from taking in on-state by its operator region
Go out cover 52, thus must change open circuit and trip assembley therefor 24 before open-circuit line protection switch.But if in advance without real
Existing this point, then forcibly open-circuit line protection switch, because not only the operator region of the switch lever 46 of hand switch 33 is closed
Cover 52 has been locked to remove and therefore forcibly manipulate the operator region when removing cover 52, and because with open circuit and trip assembley therefor

As shown in Fig. 5 A and 5B, contact board mount 36 is by ratchet 41 against switch spring 42 and spring 38
Power is maintained in its on-position, and contact plate 15 is lifted and in the pressure of spring 38 from holding convex shoulder 40 in the on-position
Under abut on contact 17,18,22, to make line protection switch be maintained in its on-state.
In the failure free operation of the line protection switch according to the present invention, electric current takes off from binding post 16 by electromagnetism
The coil 11 of button device 10 flow to the first contact 17, the second contact 18 is flow to by contact plate 15 and by primary current path 19
Wire element flow to another binding post 20.Although contact 22 is closed, it is practically without electric current and flows through with thermal trip 23 and break
Road and the primary current path 21 of trip assembley therefor 24, because primary current path 21 is by the short circuit of primary current path 19.
If due to On-line Fault road protection switch electrical appliance side produce overcurrent, magnetictrip 10 respond and
Armature 12 makes striker 14 hit the first lever arm 115, to make swing rod 114 around its pivot axis 14 ' in shown embodiment
It is middle to be pivoted along clockwise so that the swing rod is applied to contact by the contact convex portion 116 ' being arranged on the second lever arm 116

This, contact plate 15 surrounds the pivot axis formed by correspondence contact 17 ', 22 ' against the power of spring 38 and pivoted so that contact plate 15
Lifted by its corresponding correspondence contact 18 ' by contact 18 and therefore open contact 18, and first and the 3rd contact 17,22 keep
Closure.Represented in the illustrated case as spring 38 with compression spring, the compression spring is entered by the pivoting action of contact plate 15
One step is compressed, and thus makes contact plate 15 keep rabbeting with the power of increase and contact 17 and 22.In addition, magnetictrip 10 is also produced
Power, the power is applied to contact plate by swing rod 114 by the striker 14 of the magnetictrip along the power identical direction with spring 38
On 15, but act on the opposite side of pivot axis.Thus, contact plate 15 according to seesaw mode with its correspondence contact 17 ',
22 ' compress contact 17,22, so that the contact 17,22 of opening first and the 3rd when opening the second contact 18 is reliably prevented, because
When opening the second contact 18 power that is applied on contact plate 15 from the same side rather than as before from double side acting to the contact
On plate.Here, by contact plate 15 being configured as into pivot plate or seesaw realizes the reciprocal work of closing force and tensile force
With.
Here, can be by the suitable association of the power of spring 38 and magnetictrip 10 and the quality of contact plate 15 and structure
Adjust the duration of the duration of interruption for making primary current path 19, i.e. the second contact 18 of opening most short.
After opening the second contact 18 and interrupting primary current path 19, overcurrent additionally flows through the coil of magnetictrip 10
11st, contact plate 15 and now pass through primary current path 21 and thus by thermal trip 23 bimetallic element and by open circuit and
Trip assembley therefor 24.Overcurrent heats bimetallic element, but will not respond open circuit and trip assembley therefor 24.Because overcurrent is being beaten
Do not interrupt, but be only transported on primary current path 21 when opening the second contact 18, i.e. when interrupting primary current path 19, then beating
Electric arc is not produced when opening the second contact 18.
Due to overcurrent, the direction bending of the arrow A shown in the bimetallic element along Fig. 6 A of thermal trip 23, and and spine
Contact arm 143 on pawl 41 is contacted, and ratchet edge is rotated about it axis 44 clockwise against the spine not being shown specifically
The power of latch spring is pivoted, so that the retaining pin 45 on the release contact board mount 36 of ratchet 41.In the guarantor of release contact board mount 36
After holding pin 45, switch spring 42 moves the retaining pin to it in fig. 7 in shown open position.Meanwhile, it is supported on switch
Switch spring 42 on 33 switch lever 46 rotatably supported makes switch lever 46 be pivoted to that it is shown in fig. 7,
In the position for representing line protection switch off-state.
If manually switch 33 is taken to after the Failure elimination in power network in its on-position, i.e. switch thill again
In the position that bar 46 returns to shown in Fig. 5 A or 6A along clockwise movement from position shown in fig. 7, then ratchet 41 passes through
The motion also from it during shown open position moves to the on-position shown in Fig. 5 A or 6A in fig. 7 again, its
In, the ratchet is rabbeted with ratchet spring again, and the ratchet spring makes ratchet 41 be pivoted along so counterclockwise herein so that the ratchet
Formed with the retaining pin 45 contacted on board mount 36 and keep rabbeting in other words.When switch lever 46 and ratchet 41 continue to move,
The ratchet 41 being hinged on rotatable switch lever 46 makes the contact board mount 36 rabbeted by its retaining pin 45 with ratchet 41
Move to again in its closure or on-position.Here, switch spring 42 is tensioned and switch lever 46 is maintained at top dead centre position
In putting.
If disconnected according to the line protection switch of the present invention because overcurrent is transformed into it by thermal trip 23
In state, then line protection switch can again be connected at once after failure is eliminated without other measures.For overcurrent only
Be applied to the situation on line protection switch in short time because the line protection switch for example connected below have responded to and
The fault zone of already off power network, armature 12 also falls after rise and spring 38 can take contact plate again to the institute in Fig. 5 A or 6A
In the on-position shown.
But in the event of short circuit, then the magnetictrip 10 as under overcurrent situations responds and interrupts master first
Current path 19, as shown in position 43 in the fig. 8b by a dotted line, so that short circuit current flow only flows through primary current road
Footpath 21.But from unlike the situation of overcurrent, now open circuit and trip assembley therefor 24 respond, the open circuit and trip assembley therefor reality
It is upper to have interrupted primary current path 21 simultaneously and made lever 148 along pivot clockwise by means of its striker 29, such as institute in fig. 8 a
As showing.
The lever 148 being pivotally supported around pivot axis 149 has the first lever arm 150 and the second lever arm 151,
The striker 29 of open circuit and trip assembley therefor 24 is acted on first lever arm, and protuberance 152 is constructed on second lever arm, should
Protuberance is applied on the contact arm 143 of the ratchet 41 of switch lock 30, to discharge contact board mount 36 so that the contact plate branch
Frame can be switched on and off spring 42 and take in open position.
If lever 148 from its in fig. 5 shown resting position pivoted by the striker 29 of open circuit and trip assembley therefor 24
Into trip positions shown in fig. 8 a, then the lever first is connect by what the free tip of protuberance 152 was pressed onto ratchet 41
On contact arm 143, and make the ratchet against the power of ratchet spring along pivot clockwise, so that ratchet release contact board mount
36 retaining pin 45, is then brought into board mount 36 and is switched on and off spring 42 as under overcurrent situations moving its institute in figure 9 a to
In the open position shown.Herein, due to disconnection primary current path and primary current path, currentless contact 17,22 is beaten
Open, without occurring electric arc.
In order to prevent from being no longer maintained at it by magnetictrip 10 shown in fig. 8 a after primary current path is interrupted
Contact plate 15 in position fall back in its closing position (this may cause, short circuit current flow flow through primary current path 19 and
Undesirable electric arc is produced when opening the first and second contact 17 and 18), so construct the He of the second lever arm 151 of lever 148
The extension 117 of swing rod 114, makes the second lever arm 151 act on the side 117 ' of extension 117 by its free end 151 '
On, thus, once the striker 14 of magnetictrip 10 no longer makes swing rod be maintained in its opening or trip positions, positioned at its dropout
The swing rod 114 of position is prevented from returning in its resting position.Therefore, it is switched off and the pivotable lever 148 of trip assembley therefor 24
Second lever arm 151 is by swing rod 114 and thereby contact plate 15 is maintained at into the second contact 18 opened and in primary current path 19
In disconnected position so that primary current path and primary current path all reliably keep no current, until contact plate 15 should with carrying
The switch spring 42 that the contact board mount 36 of contact plate has been switched on and off lock 30 is moved in open position shown in figure 9 a.
Herein, open circuit and trip assembley therefor 24 are suitably made up of Fuse assembly, the fusible link of the Fuse assembly and/or guarantor
Hold silk makes contact plug 29 be maintained at it shown in Fig. 5 A, 5B and 6A against the power of dropout spring in a manner not shown in detail
In ready position.Once the fusible link of Fuse assembly and holding silk are arranged in Fuse assembly due to big short circuit current flow fusing
Dropout spring move in its trip positions with making the impact type of striker 29, thus the striker is as described above by lever 148
Ground manipulates switch lock 30.
