A hole 122 is formed in the cover of the front surface 120 to expose the overcurrent relay 131 abroad. A trigger button 125 and a close button 126 are respectively provided on the surface cover previous 120 so that you manually switch the connection and the switching off switching mechanism 117.

The trigger device module 140 is installed on the rear side of the overcurrent relay 131. The switching mechanism 117 is arranged on one side of the module of firing device 140 to thereby perform a trigger operation of the fixed contactor and the mobile contactor according to the trip command that detects a relay loss current of overcurrent 131.

As depicted in Figures 4 and 5, the trigger device module 140 may include a housing 141 provided with first and second cavities of reception of the arms 148 and 149 (figures 6 and 7) grooved and sized so that they receive tightly the drive arms arranged in main shaft 111 with various separations between phases, a drive 161 received in the housing 141 to generate a handling force when the overcurrent relay 131 Outputs the trigger signal, a reset plate 171 installed in housing 141 for interconnection with the shaft main 111 so that it initializes an output part of the drive 161 and a trigger cursor 181 that can slide to along the housing 141 and connected to the switching mechanism 117 so that it allows the trigger operation of the mechanism of switching 117 when drive 161 performs an operation of Shooting.

The trigger device module 140 additionally includes a 250 timing output device of interconnection with the main shaft 111 to output a signal with a previously set timing after that the fixed contactor comes into contact with the mobile contactor, a overcurrent relay interconnection trip device 280 that interconnects with the overcurrent relay separation 131 to allow the switching mechanism 117 to be triggered, and a trigger signal output device 290 that interconnects with drive 161 to output an outdoor trip signal when drive 161 performs the shooting operation.

The housing 141 may include a main body of the housing 142a provided with an open reception space in its inside and provided with a hole in its front side and a housing cover 142b to be fixed in one piece to the main body of the housing 142a by a plurality of screws 143 so that they close the hole in the front side of the main body of the housing 142a.

The main tree 111 may include a plurality of actuator arms of the mobile contactor for actuate the mobile contactor of each phase separated from each other to have different separations between phases and an arm of actuation of the switching mechanism connected to the mechanism of switching 117. As shown in Figure 6, a plurality of actuator arms of the mobile contactor 113 with a relatively short phase separation L1 are arranged to intervals along a first main shaft 112a provided with a relatively small capacity (for example, 2000 A). How I know depicted in figure 7, a plurality of drive arms of the mobile contactor 113 with a relatively phase distance long L2 are arranged at intervals along the second tree main 112a provided with a relatively greater capacity (for example, 4000 A).

Also, the second main tree 112b is configured in such a way that a drive arm of the plate reset 114 is separated from the drive arms of the mobile contactor 113 due to its relatively large separation between phases The first main tree 112a may not present separately no actuator arm of the plate reset since the drive arms of the mobile contactor 113 actuate the mobile contactor and the plate reset 171. Therefore, the second reception cavity of arms 149 exists as an empty space. Then the first main tree 112a (hereafter referred to as the tree main 111) to which the drive arm of the plate reset and drive arms of the mobile contactor They are integrated with each other will be described in an exemplary manner.

The drive 161 that generates a force of handling when the overcurrent relay 131 outputs the firing command and reset plate 171 rotated by the interconnection with main shaft 111 to reset a part drive handling 161 are installed in the housing 141.

As depicted in Figures 8 to 10, the drive 161 may include a stator 162 which generates a magnetic force when energy is applied to it, a piston 165 protruding by the magnetic force of stator 162 and a spring 169 which applies an elastic force in a direction such that the piston 165 is forced to protrude. Stator 162 may include a housing 163 and a coil 164 disposed inside the housing 163. A handling part 167 that interconnects with the piston 165 is installed at one end of drive 161. The part of manipulation 167 is composed of two pieces, which stand out both towards the reset plate 171 when the 165 piston

An extreme part of the plate reset 171 is arranged articulated in a tree swivel 173 and a curved end portion 174 which drives the timing output device 250 is formed in the other end of the reset plate 171. Springs Circular 176 are coupled to both ends of the rotating shaft 173. A part of the reset arm 175 is shaped curve mode on the side of the reset plate 171 at one end of the rotating shaft 173 so that it can pressing on one of the handling parts 167 of the drive 161 to return drive 161 to its position initial.

A drive reset assembly 230 is provided between the main shaft 111 and drive 161 to restore (return) drive 161 to its initial position. The drive reset assembly 230 may include a reset plate 171 that interconnects with the main shaft 111, a cursor 231 disposed on one side of the reset plate 171 and pressed to be displaced when the reset plate 171 is rotated and a reset arm 238 provided with one end that is in contact with the cursor 231 to be rotated and the other side pressing on the piston 165 of the drive 161 to restore the drive 161 to its initial position. The reset arm 238 may be provided with a reset spring.
foundation 239 which applies an elastic force to the reset arm 238 to force it into its initial position.

As shown in Figure 9, cursor 231 may include a housing 233, a reset pin 235 coupled to be taken out or inserted inside the housing 233 and a stabilization element 237 arranged in the housing 233 to be expanded or contracted and implanted as a compression coil spring to press on the pin reset 235 to force it out of accommodation 233. Here, housing 233 is pressed when the plate rotates reset 171 and is guided by the guided part (no represented) formed in the housing 141 to be displaced linearly towards the reset arm 238.

As depicted in Figures 4 and 5, a trigger cursor 181 is arranged in the direction along in the side part of the housing 141 to be slid between a closing position and a firing position. A reception party 183 is formed in an area of the trigger cursor 181 to receive a part of the switching mechanism 117. Thus, the switching mechanism 117 is limited in a standby state to perform the shooting operation. When the shooting cursor 181 is moved to the firing position, the mechanism part switching 117 in contact with the receiving part 183 is pressed to be mobile and thus its state is released limited. Accordingly, the switching mechanism 117 can Perform the trigger operation immediately. A notch of guided 185 provided with an elongated shape is formed in the cursor trigger 181 to receive guide pins 146 that protrude of a side part of the housing 141. An extreme part of the cursor trigger 181 is in contact with the handling part 167. A pressure cursor 191 to press the trigger cursor 181 towards the firing position is arranged at one end of the cursor of shot 181 next to the trigger cursor 181.

A guide notch 195 provided in one way long is formed in the pressure cursor 191 to receive the guiding pins 146 protruding in the housing 141. A spring of the pressure cursor 197 which applies an elastic force to force the pressure cursor 191 towards the firing position is connected to one end of the pressure cursor 191. A part of contact 196 which is in contact with the trigger cursor 181 to press on it is formed on the pressure cursor 191

A latch element 211 is arranged in a pressure cursor side 191 to set pressure cursor 191 in the closed position. The latch element 211 is installed so you can rotate between a fixing position to fix the pressure cursor 191 and a release position to release the set pressure cursor 191. The latch element 211 rotates centered around a rotating shaft 213 formed in its part central. A washer 217 and circular springs 218 are provided on the rotating shaft 213 to fix the latch element 211. A butt projection 215 is formed at one end of the element of latch 211 and can be inserted inside a slot fixation 193 formed in the pressure cursor 191 to be coupled for the same. The other end of latch element 211 is in contact with the handling part 167 of the drive 161. A latch element spring 219 is provided in the element of latch 211 to reset latch element 211 to its initial position. The latch element 211 is pressed by the handling part 167 to be turned to the position of release when drive 161 performs the operation of shot accordingly, pressure cursor 191 is allowed to be moved to the firing position. Also, when the drive 161 is restored to its initial position by the drive reset assembly 230, the element of latch 211 moves the trigger cursor 181 to the position of tripping by the pushing force of the spring of the element latch 219.

As depicted in Figures 11 and 12, the timing output device 250 is used to perform the so-called current release function during closing (MCR - release by current during closing) so that overcurrent relay 131 sets a current value to prevent a high current from being introduced on one side of charge and detect the current entered to open in that way Instantly the circuit breaker at the time of the introduction of a high current that is greater than a current value previously established. This is, so that the relay of overcurrent 131 perform the current release function during the MCR closure, it is required to distinguish two cases, that is, a case in which the loss current is blocked (that is, the fixed contactor and mobile contactor separate) when the circuit breaker is closed and another case in which the loss current is connected when the circuit breaker is closed (ie the contactor fixed and the mobile contactor are in contact) on a line (or trajectory) in which the circuit breaker has been disconnected due to a loss occurred previously. In order to distinguish the two cases of this type, the timing output device 250 emits from output a contact signal with a constant timing after that the fixed contactor and the mobile contactor have entered contact with each other.

As depicted in Figure 11, the timing output device 250 may include a switch 251 arranged on one side of the main shaft 111 for switch the connection and disconnection of the fixed contactor and the mobile contactor, a delay element 261 arranged between the tree main 111 and switch 251 so that it can be rotated by interconnecting with the rotation of the main shaft 111 and the operation of switch 251 with a pre-timer established after the fixed contactor and the mobile contactor come into contact with each other and a spring of the element of delay 270 provided with an end connected to the delay element 261 so that you can apply an elastic force on a direction in which the delay element 261 is forced into contact with switch 251 when main shaft 111 is turned in a closing direction and applies an elastic force to keep delay element 261 separate from switch 251 when the main shaft 111 is turned in a direction of opening.

With reference to Figure 5, switch 251 is installed in housing 141 and delay element 261 is rotatably installed on one side of switch 251. A contactor 253 (figure 11) is arranged on one side of the switch 251. A stop 255 which limits the rotation of the delay element 261 it is formed in an upper area of switch 251. The spring of the delay element 270 is connected to one side of the element of delay 261.

The delay element 261 may include a rotating shaft 263 arranged next to main shaft 111, a first contact part 265 extending to one end from the rotating shaft 263 to come into contact with the switch 251 and a second contact part 268 extending to the other end from the swivel shaft 263 and that rotates along with the first contact part 265. The second contact part 268 may include a rounded part 266 so that it can enter gently contact the curved end portion 174 of the plate reset 171 when the main shaft 111 is rotated in the opening direction Here, when the delay element 261 is turned through the dead center of the spring by a outside force or similar in one direction to be carried by of switch 251, the curved end portion 174 comes into contact with the rounded part 266 to thereby limit the rotation of the delay element 261. In addition, the curved end portion 174 is shaped to be inclined with respect to the delay element 261. This is configured so that it always ensures a constant timing. With this purpose, when the tree main 111 is rotated from the opening position to the position of closing, the reset plate 171 is rotated by a force spring-loaded spring plate reset 178, which then makes the curved end part come into contact 174 with the rounded part 266, resulting in the rotation of the element delay 261 in an address where it separates from the switch 251

The spring of the delay element 270 which apply the elastic force to rotate the delay element 261 is connected to a zone of the delay element 261, that is, to the first contact part 265. The spring of the delay element 270 applies an elastic force in a direction in which the 261 delay element is forced to contact the switch 251, when the main shaft 111 is in the position of closing while applying an elastic force in one direction such that the delay element 261 is kept separate from the switch 251 because delay element 261 is rotated by passing through the dead center of the spring of the delay element 270, when the main shaft 111 is in the open position.

Referring to figure 3, a overcurrent relay interconnection trip device 280 is installed on the rear side of the overcurrent relay 131 so that it allows the firing operation to be carried out whereby the fixed contactor and the mobile contactor are separated from each other, through interconnection with separation of overcurrent relay 131.

As depicted in Figures 13 to 15, the overcurrent interconnect trip device 280 can include a part of the rotating shaft 283 installed so rotating on the trigger device module 140, an arm of manipulation 285 that extends along a radial direction from an area of the rotating shaft part 283 to enter contact with overcurrent relay 131, an arm of drive 287 extending from the other area of the part of the rotating shaft 283 to be rotated simultaneously when the part of the rotating shaft 283 rotates, therefore pressing on the drive projection 188 of the trigger cursor 181, by which the trigger device module 140 is pressed into the time to perform the trigger operation and an elastic element 289 for the application of an elastic force in one direction in the that the manipulation arm 285 is forced to come into contact with the overcurrent relay 131.

The rotating shaft part 283 is installed rotatably on the front surface of the housing 141 of the trigger device module 140 in one direction across the housing 141. The handling arm 285 which protrudes in a radial direction of the rotating shaft part 283 to be in contact with the overcurrent relay 131 is made up of rotating form in an area of the rotating shaft part 283. The drive shaft 287 is formed in the other area of the part of the swivel shaft 283. The drive arm 287 is in contact with the trigger cursor 181 to allow the cursor to shot 181 is moved to the firing position.

Drive arm 287 extends to contact the actuator boss 188 of the cursor trigger 181 to thereby press on the trigger cursor 181. The elastic element 289 is arranged in the part of the tree swivel 283 to apply an elastic force in such a direction that the part of the rotating shaft 283 comes into contact with the relay of overcurrent 131. The elastic element 289 accumulates a force elastic when overcurrent relay 131 is set and rotates the actuation arm 287 by means of accumulated elastic force when the overcurrent relay 131 is separated. Therefore, the trigger cursor 181 is moved to the firing position, so which movement of the switching mechanism 117 is actuated to perform the shooting operation.

Moreover, a PCB (circuit board printed) 144 connected to overcurrent relay 131 is set to the lower area of the housing 141 by means of screws 147. The plate printed circuit 144 is provided with a connector 145 to be connected to overcurrent relay 131 (figure 5).

As depicted in figures 12 and 16 the trigger signal output device 290 interconnects with the drive 161 actuated when overcurrent relay 131 issues a trip command to display externally that drive 161 has performed the trip operation.

The trigger signal output device 290 of the trigger device module 140 may include a switch 293 to output a signal at the time of being contacted and an interconnection element 313 upon contact with switch 293 when trigger cursor 181 is in the firing position.

Switch 293 is installed so that can be received on one side of drive 161 in the housing 141 and the 295 contactors which come into contact in the moment of being pressed they are formed on one side of the switch 293. Interconnection element 313 may include a tree swivel 315 in its center and two arm parts 317 that are They extend in different directions from the rotating shaft 315. The two arm parts 317 respectively extend towards the switch 293 and toward the trigger cursor 181. A piece of contact 319 is disposed between contactors 295 and the element of interconnection 313 to uniformly press on the contactors 295. A pressure rod 187 extends at the cursor trigger 181 to press on the arm part 317 of the interconnection element 313 for rotation, when the cursor of shot 181 is moved to the firing position.

On the other hand, as represented in the Figures 14 and 15, a reset assembly 320 is installed on one side of the housing 141 to reset the device Output of trigger signal 290 to its initial position. Set reset 320 of the signal output device shot 290 may include a reset arm 321 arranged on one side of the pressure cursor 191 to be rotated between a firing position and closing position so that it displaces the pressure cursor 191 to the closed position and a dipstick restoration 331 that stands out by interconnecting with the reset arm 321 to be exposed from one side of the overcurrent relay 131 outward and restoring arm reset 321 to the closed position when held down.

Reset arm 321 may include a rotating shaft 323 in its central part and two parts of the arm 325 that extend respectively in different directions a of the other. 327 circular springs and a 328 washer for the reset arm coupling 321 are coupled to the rotating shaft 323. An anterior end part of the rod reset 331 extends forward from the body main circuit breaker 110. A rod spring reset 337 is provided on the reset rod 331 to apply an elastic force such that the rod of reset 331 can be shifted to the arm of reset 321. As shown in Figure 1, a button restoration 335 is provided at the front end of the reset rod 331 so that it drives the rod of reset 331 in a pressurized manner. Here, the arm of reset 321 can be configured to be powered by a motor. Also, the anterior extreme part of the arm of reset 331 can be set to be directly exposed outside.

With this setting, when the relay overcurrent 131 issues a trip command, the drive 161 generates a magnetic force as it is applied energy to the stator 162 and the piston 165 is made to protrude through the magnetic force When the piston 165 protrudes, the part of manipulation 167 interconnects to be moved to the position of Shooting. At that time, latch element 211 is pressed by the handling part 167 to be turned to the position of release.

When latch element 211 is rotated, the pressure cursor 191 is moved to the firing position by the spring force of the pressure cursor spring 197. By consequently, the trigger cursor 181 is pressed to be shifted to the firing position. The cursor movement of trigger 181 to the firing position releases the mechanism of switching 117 of being limited by being in contact with the trigger cursor 181. Switching mechanism 117 performs then the firing operation, which causes the tree Main 111 is turned to the firing position. Therefore, the fixed contactor and the mobile contactor are separated from each other. Meanwhile, when the trigger cursor 181 is moved to the trigger position, the interconnection element 313 that is in contact with the pressure rod 187 is pressed to be turned centered around the rotating shaft 315. The element of rotated interconnection 313 presses on the contact piece 319. The pressed contact piece 319 comes into contact with Contactors 295 of Switch 293. Switch 293 then emits Output a trigger signal.

When the main shaft 111 is turned to the firing position, the reset plate 171 is turned to the trigger position by the drive arm of the plate reset 114. Depending on the rotation of the reset plate 171, the cursor 231 is slid being pressed by the plate reset 171. So, reset arm 238 is turned by being pressed by the reset pin 235 of the cursor 231. The reset arm rotated 238 presses the piston 165 so that it restores drive 161 to its position initial. Here, when piston 165 is restored to its position initial, the reset arm 238 stops being turned, so which stops the reset pin 235 of cursor 231. In this state, if the housing 233 is pressed to be moved forward, the stabilization element 237 is compressed to Perform a stabilization function.

When the reset plate 171 is turned to firing position, reset plate 171 comes into contact with the handling part 167 of the drive 161. Accordingly, the handling part 167 is restored to Your initial position.

Here, since trigger cursor 181 is limited by pressure cursor 191, trigger cursor 181 is placed in the firing position so that the trigger cursor close again. When a user has inspected the reason for the shot, the user presses the button reset 335 to rotate reset arm 321 to the closing position by means of the reset rod 331. When the reset arm 321 is turned to the position of closing, the pressure cursor 191 that comes into contact with the arm reset 321 is pushed to be moved to the closing position According to the movement of the pressure cursor 191 a the closing position, the latch element 211 is turned to the closing position by the elastic pushing force of the spring latch element 219. When latch element 211 is turned to the closed position, the pressure cursor 191 is set in the closed position and the trigger cursor 181 entering contact with latch element 211 is pressed by the latch element 211 to be moved to the position of closing, thus being in a state where it can be shot.

While the reset plate 171 is turned to the firing position, the curved end part 174 press on the delay element 261 of the output device of timing 250. The delay element 261 is then rotated in one direction to be separated from switch 293. Here, the Delay element spring 270 passes through the neutral. Therefore, the timing element 261 applies a force elastic push towards a direction to be separated from switch 251. Moreover, when the reset plate 171 is turned to the closed position due to the rotation of the shaft Main 111 to the closed position, the reset plate 171 is turned to the closed position by the elastic force of the reset plate spring 178.

The curved end portion 174 of the plate reset 171 presses on the first contact 265 so that the delay element 261 comes into contact with the contact 253 of switch 251 with the previously set timing after the fixed contactor comes into contact with the contactor mobile so that switch 251 emits output a outdoor detection signal When the first contactor 265 enters in contact with switch 251, switch 251 emits output the signal. Meanwhile, when the delay element 261 is rotated by an external force or similar in the direction so that it near switch 251, delay element 261 is limited in the rotation due to the contact between the rounded part 266 and the curved end part 174.

When the main shaft 111 is turned to the closed position, the reset plate 171 rotates in the clockwise (in the drawing) by force spring elastic plate 178. The part curved end 174 of reset plate 171 presses then the rounded part 266 of the second contact part 268 up (in the drawing) so that it allows the element of delay 261 is turned in one direction away from the switch 251. Here, according to the interaction between the curved end portion 174 and the rounded part 266, the delay element 261 is rotated such so that the spring of the delay element 270 passes through the neutral and thus the elastic force of the spring of the delay element 270 is applied in a direction such that the delay element 261 is separated from switch 251.

The curved end portion 174 of the plate reset 171 rotated through the rounded part 266 is rotated continuously to press on the first part of contact 265, thereby rotating the delay element 261 to That passes through the neutral. Therefore, the switch 251 is allowed to always output a signal with a constant timing after the fixed contactor enters Contact with the mobile contactor. The delay element 261 is keeps rotated by the elastic pushing force of the spring delay element 270 and therefore the first part of contact 265 is brought into contact with contactor 253 of switch 251. Switch 251 then outputs an signal to the outside when the first contact part 265 enters contact with contactor 253.

Meanwhile, at the time of examining or replace the overcurrent relay 131, when the relay overcurrent 131 is separated from the device module of shot 140, the handling arm 285, the tree part swivel 283 and drive arm 287 are rotated simultaneously by the accumulated elastic force of the element elastic 289. When drive arm 287 is rotated, the drive projection 188 is pressed such that the trigger cursor 181 is shifted down along the housing 141. Also, the part of the switching mechanism 117 which is in contact with the trigger cursor 181 is pressed so which releases the limited switching mechanism 117. By consequently, the switching mechanism 117 performs the operation Shooting
