As Figure 11 and shown in Figure 12, time delay output apparatus 250 is used to carry out so-called MCR (making current release) function, so that overcurrent relay 131 is provided with the electric current of current value to prevent from high current is incorporated into load side and detect introduces, thus when the high current of introducing greater than the predetermined current value moment open circuit breaker.That is to say, carry out the MCR function in order to make overcurrent relay 131, need two kinds of situations of difference, promptly, on the circuit (path) that circuit breaker has been disconnected, fault current is hindered the situation of (, fixed contact and movable contactor are separated) when circuit breaker is closed, and the situation that fault current is threaded off when circuit breaker is closed (, fixed contact contacts with movable contactor).In order to distinguish both of these case, after fixed contact and movable contactor were in contact with one another, time delay output apparatus 250 output devices had the activation signal of constant delay.
As shown in figure 11, time delay output apparatus 250 can comprise: switch 251, and its side that is arranged at main shaft 111 is to be switched on or switched off fixed contact and movable contactor; Postpone member 261, it is arranged between main shaft 111 and the switch 251, being rotated by rotation interworking with main shaft 111, and after fixed contact and movable contactor are in contact with one another to preset delay operation switch 251; And delay member spring 270, it has an end that is connected on the delay member 261, make when main shaft 111 rotates on closing direction, it can promote postpone to apply elastic force on member 261 and the direction that switch 251 contacts, and when main shaft 111 rotated on opening direction, it can apply elastic force to keep postponing member 261 and switch 251 intervals.
With reference to Fig. 5, switch 251 is installed in the casing 141, and postpones the side that member 261 is rotatably installed in switch 251.Contactor 253 (with reference to Figure 11) is arranged on a side of switch 251.The retainer 255 of limited delay member 261 rotations is formed on the upper area of switch 251.Postponing member spring 270 is connected on the side that postpones member 261.
Postponing member 261 can comprise: rotating shaft 263, and itself and main shaft 111 are arranged side by side; First contact site 265, it extends to an end that will be contacted by switch 251 from rotating shaft 263; And second contact site 268, it extends to the other end and with 265 rotations of first contact site from rotating shaft 263.Second contact site 268 can comprise rounded portions 266, and when rotating on opening direction with convenient main shaft 111, it can smoothly contact with the crooked end 174 of restoring board 171.Herein, when postponing member 261 near on the direction of switch 251 during by the dead point of rotations such as external force by spring, crooked end 174 contacts with rounded portions 266, thus the rotation of limited delay member 261.In addition, crooked end 174 is formed obliquely with respect to postponing member 261.This structure makes it possible to guarantee all the time constant delay.For this reason, when main shaft 111 when the enable possition rotates to make position, restoring board 171 is rotated by the resiliency urged power of restoring board spring 178, and this makes crooked end 174 contact with rounded portions 266 then, cause postponing member 261 with switch 251 separated directions on rotate.
Apply elastic force and be connected in a zone that postpones member 261, i.e. first contact site 265 so that postpone the delay member spring 270 of member 261 rotations.When main shaft 111 is in the close position, postpone member spring 270 and promoting to postpone to apply elastic force on member 261 and the direction that switch 251 contacts, yet when main shaft 111 is in the enable possition, because 261 rotations of delay member by postponing the dead point of member spring 270, therefore make delay member 261 and switch 251 keep applying elastic force on the isolated direction.
With reference to Fig. 3, overcurrent relay interworking trip gear 280 is installed in the rear side of overcurrent relay 131, thereby allow to carry out thread off operation, thus by with the interworking of the dismounting of overcurrent relay 131, fixed contact and movable contactor are separated from each other.
To shown in Figure 15, overcurrent interworking trip gear 280 can comprise as Figure 13: shaft 283, and it is rotatably installed in trip gear module 140 places; Motion arm 285, a zone of 283 extends to overcurrent relay 131 and contacts along radial direction from shaft for it; Actuating arm 287, extend in its another zone from shaft 283, rotating simultaneously when shaft 283 rotations, thereby pushes the driving protuberance 188 of dropout slider 181, and trip gear module 140 is pressed and operates to carry out to thread off thus; And elastic component 289, it is promoting to apply elastic force on motion arm 285 and the direction that overcurrent relay 131 contacts.
On the other hand, the PCB (printed circuit board (PCB)) 114 that will be connected to overcurrent relay 131 by screw 147 is fixed to the lower area of casing 141.PCB144 is provided with the connector 145 (with reference to Fig. 5) that is connected on the overcurrent relay 131.
As Figure 12 and shown in Figure 16, trip signal output device 290 and actuator 161 interworkings, described actuator 161 will be threaded off to instruct to output at overcurrent relay 131 and be turned round when outside demonstration actuator 161 has been carried out the dropout operation.
The trip signal output device 290 of trip gear module 140 can comprise: switch 293, and it is output signal when being touched; And interworking member 313, it contacts with switch 293 when dropout slider 181 is in the dropout position.
Switch 293 can be installed in a side place of the actuator 161 in the casing 141 with holding, and the contactor 295 that is touched when being pressed is formed on a side place of switch 293.Interworking member 313 can be included in the rotating shaft 315 of the center, and two arms 317 that extend from rotating shaft 315 in different directions.Two arms 317 extend towards switch 293 with towards dropout slider 181 respectively.Contact chip 319 is arranged between contactor 295 and the interworking member 313 so that equably by being pressed on the contactor 295.Pressing lever 187 extends at dropout slider 181 places, when moving to the dropout position with box lunch dropout slider 181 by the arm 317 that is pressed in the interworking member 313 that is used to rotate.
On the other hand, as Figure 14 and shown in Figure 15, reset components 320 is installed in a side place of casing 141, so that trip signal output device 290 is reset to its initial position.The reset components 320 of trip signal output device 290 can comprise reset arm 321 and release link 331.Described reset arm 321 is arranged on a side place of pushing slider 191, with rotatable between dropout position and make position, moves to make position thereby will push slider 191; Described release link 331 is exposed to the outside by giving prominence to the side from overcurrent relay 131 with reset arm 321 interworkings, and when being pressed reset arm 321 is reset to make position.
Based on this structure, when instruction was threaded off in overcurrent relay 131 outputs, actuator 161 produced magnetic force, and described magnetic force is applied on the stator 162 as power, and makes mover 165 outstanding by described magnetic force.When mover 165 was given prominence to, operating portion 167 interworkings were to be moved to the dropout position.At that time, latch member 211 is operated portion 167 and pushes to rotate to the off-position.
When latch member 211 rotations, push slider 191 and move to the dropout position by the elastic force of pushing slider spring 197.Therefore, dropout slider 181 is pressed and moves to the dropout position.Dropout slider 181 to the motion of dropout position makes switching mechanism 117 avoid by being limited with contacting of dropout slider 181.So switching mechanism 117 is carried out the operation of threading off, this makes main shaft 111 rotate to the dropout position.Therefore, fixed contact and movable contactor are separated from each other.Simultaneously, when dropout slider 181 moved to the dropout position, the interworking member 313 that contacts with pressing lever 187 was pressed, thereby was center rotation with rotating shaft 315.The interworking member 313 of rotation is by being pressed on the contact chip 319.The contact chip 319 that is pressed contacts with the contactor 295 of switch 293.So, switch 293 output trip signals.
When main shaft 111 rotated to the dropout position, restoring board 171 rotated to the dropout position by restoring board actuating arm 114.According to the rotation of restoring board 171, slider 231 is pushed thereon by the plate 171 that is reset and is slided.Then, reset arm 238 is rotated by being pushed thereon by the return pin 235 of slider 231.The reset arm 238 of rotation is pushed mover 165, thereby actuator 161 is reset to its initial position.In this article, when mover 165 reset to its initial position, reset arm 238 was no longer rotated, and this makes the return pin 235 of slider 231 stop.In this state, if shell 233 is pressed to move forward, then level and smooth member 237 is compressed to carry out smoothing function.
When restoring board 171 rotates to the dropout position, the operating portion 167 of restoring board 171 contact actuators 161.Therefore, operating portion 167 is reset to its initial position.
Herein, because dropout slider 181 is by pushing slider 191 restrictions, so dropout slider 181 is positioned at the dropout position, in case anti-avulsion button slider is closed once more.When the user checked out the reason of dropout, the user pushed reset button 335, so that make reset arm 321 rotate to make position by release link 331.When reset arm 321 rotated to make position, the slider 191 of pushing that contacts with reset arm 321 was prevented from and moves to make position.According to pushing the motion of slider 191 to make position, latch member 211 rotates to make position by the resiliency urged power of latch member spring 219.When latch member 211 rotates to make position, push slider 191 and be fixed to make position, and the dropout slider 181 that contacts with latch member 211 is pushed by latch member 211 and is moved to make position, thereby makes dropout slider 181 be in the state that can thread off.
When restoring board 171 rotated to the dropout position, crooked end 174 was by on the delay member 261 that is pressed in time delay output apparatus 250.Then, postpone member 261 with switch 293 direction at interval on rotate.Postpone member spring 270 herein, and pass through the dead point.Therefore, postpone member 261 towards applying resiliency urged power with switch 251 direction at interval.On the other hand, when since main shaft 111 when the rotation of make position makes that restoring board 171 rotates to make position, restoring board 171 rotates to make position by the elastic force of restoring board spring 178.
The crooked end 174 of restoring board 171 is by being pressed on first contactor 265, so that at fixed contact with after movable contactor contacts, make with default time-delay to postpone member 261 and contact, thereby make switch 251 that detection signal is outputed to the outside with the contactor 253 of switch 251.When first contactor 265 contacts with switch 251, switch 251 output signals.Simultaneously, when postpone member 261 by external force etc. when rotating on the direction of switch 251, postpone member 261 because the contact between rounded portions 266 and the crooked end 174 is limited to rotate.
When main shaft 111 rotated to make position, restoring board 171 was by elastic force (in the accompanying drawing) rotation in the clockwise direction of restoring board spring 178.Then, the crooked end of restoring board 171 174 upwards (in the accompanying drawing) is pushed the rounded portions 266 of second contact site 268, postpones member 261 and rotates on the direction of switch 251 further away from each other thereby make.Herein, according to the interaction between crooked end 174 and the rounded portions 266, make 261 rotations of delay member,, thereby make the elastic force that postpones to apply on member 261 and switch 251 direction at interval delay member spring 270 so that delay member spring 270 passes through the dead point.
The crooked end 174 of the restoring board 171 of rotation continues rotation with by being pressed on first contact site 265 via rounded portions 266, passes through the dead point thereby delay member 261 is rotated.Therefore, at fixed contact with after movable contactor contacts, make switch 251 all the time output device the signal of constant delay is arranged.Delay member 261 is tried hard to keep by the resiliency urged that postpones member spring 270 and is held rotation, and first contact site 265 is contacted with the contactor 253 of switch 251.Then, when first contact site 265 contacted with contactor 253, switch 251 outputed to the outside with signal.
Simultaneously, under the situation of check or replacement overcurrent relay 131, when with overcurrent relay 131 when trip gear module 140 disassembles, the elastic force that gathers by elastic component 289 rotates motion arm 285, shaft 283 and actuating arm 287 simultaneously.When actuating arm 287 rotations, drive protuberance 188 and be pressed, so that dropout slider 181 moves down along casing 141.In addition, the part of the switching mechanism 117 that contacts with dropout slider 181 is pressed, to discharge confined switching mechanism 117.Therefore, switching mechanism 117 is carried out the operation of threading off.
