This is because there is a request for replacement. Incidentally, the body 23 and the cover 80 constitute a power transmission.

Figure vJ6 shows an electric circuit diagram, in which a series circuit including a shorting coil 33, a bimetal 39, contacts 36, 75, etc. is inserted between terminal parts 70 and 73. In addition, an auxiliary contact SW consisting of an auxiliary fixed contact 66 and an auxiliary contact spring 67
1 and the coil 5 of the electromagnet section 3 are connected to the auxiliary terminal 22.
It is connected to the. An external switch SW2 is connected to the auxiliary terminal 22. The feature of this breaker is that even if the handle 60 is turned on, the contacts 36.75 will not be turned on and the main circuit will not be energized unless the forger operates the external switch SW2. Then, when the external switch SW2 is turned off or the handle 60 is turned off to turn off the auxiliary contact SW1, the auxiliary contact SW1 and the external switch SW2 are connected to the coil 5 of the electromagnet section 3 in series. Since it is inserted, the electromagnet part 3 is cut off, the contacts 36.75 are opened, and the main circuit is cut off.

Next, the operation of this breaker will be explained.

5 shows a sectional view taken along the line AA in FIG. 3, and FIG. 1 shows a sectional view taken along the line BB in FIG. 3. Figure 5 (a) and @Figure 1 (
a) shows the on state, and Fig. 5 (1]) and Fig. 1 (1]
) shows the off state when the handle 60 is on and the electromagnet part 3 is off, FIG. 5(e) and FIG. 1(c) show the off state, and FIG. 5(d) and FIG. d) shows a trip condition.

First, when the handle 60 is turned on as shown in FIG. 1(a) from the off state of FIG. 1(c), the protrusion 60c of the handle 60 separates from the auxiliary contact spring 67 of the auxiliary contact SW. 67 returns and the auxiliary contact SWl is closed as shown in FIG. 5(a). Therefore, when the external switch Sw2 shown in FIG. 6 is on, the coil 5 of the electromagnet part 3 is excited, and the movable core 7 is attracted to the fixed core 6 as shown in FIG. 5 and FIG. 1(a). be done. When the movable iron core 7 is attracted, the conversion shaft 11 connected to the movable iron core 7 and the U-shaped bin 16 rotates clockwise about the shaft 13, so that the coupling bin 18 is rotated by the rotation of the conversion shaft 11. It moves downward with the movement. When the connecting bottle 18 moves downward, the link 45 connected to the connecting bottle 18 rotates about the rotating shaft 50 in the direction of the half-hour hand. Therefore, the interlocking plate 26 disposed on the ↑ₛ side of the link 45 is moved down against the return force of the opening spring 29. When the interlocking plate 26 moves downward, the movable contact 27 and the contact pressure spring 28 are located in the hole 26a of the interlocking plate 26 as shown in FIG. 5(a). 28 is moved downward, and the movable contact 36 of the movable contact 27 and the fixed contact 75 are moved by the contact force of the contact pressure spring 28.
will come into contact with the main circuit and the main circuit will be energized.

Here, when only the electromagnet section 3 is turned off with the external switch SW2, the movable core 7 returns to the left side of the figure due to the return force of the spring 10, as shown in FIGS. 5 and 1 (11). . This movement of the movable iron core 7 causes the conversion shaft 11 to rotate counterclockwise about the shaft 13. This conversion axis 11
By rotating in this direction for half an hour, the connecting pin 18 is moved upward, and the link 45 is rotated clockwise. Therefore, the interlocking plate 26 whose urging force by the link 45 has been released is moved upward by the return force of the opening spring 29, and the movable contact 27 is also moved upward, and the contacts 36.75 are opened and separated. Also, at this time, the biasing force of the spring 35 that biases the base of the movable contact 27 together with the restoring force of the opening spring 29 rotates half an hour in this direction about the protrusion 37a at once to open the contact. It is something.

Next, when the handle 60 is turned off from the on position, the protrusion 60c of the handle 60 presses the auxiliary contact spring 67 of the auxiliary contact SW1 downward, as shown in FIG. 5 and FIG. , the auxiliary contact spring 67 is the auxiliary fixed contact 66
The auxiliary contact SW1 opens further away. Therefore, the opening of this auxiliary contact SW1 cuts off the current supply to the electromagnet 3, and the connecting pin 18 and the like operate in the same manner as in the above case to open the contact 36.75.

Next, the case of trip state will be explained. First, the case where the main circuit is short-circuited will be explained. In the case of a short-circuit, a large current flows, so that an electromagnetic force is generated in the short-circuit coil 33, causing a trip operation.

Here, in a normal state before a short circuit occurs, as shown in FIG. It is located at the bottom of 44. The latch plate 48 is the latch engagement plate 5
It is engaged with the engagement piece 57 of No. 3.

Furthermore, the engaging portion 56 of the latch engaging plate 53 is shown in FIG.
As shown in FIG. 3, it engages with the head 34a of the drive pin 34. When a short circuit occurs, the electromagnetic force generated in the short circuit coil 33 attracts and moves the drive bin 34 downward. This drive bin 3
4, the engaging portion 56 is pressed into contact with the pin 5.
5 as an axis, the pinch engagement plate 53 rotates in this direction by half an hour. Then, the latch plate 48, which is disengaged from the engagement piece 57 of the clutch engagement plate 53, becomes in the 7-way state, and the link 45
is urged upward via the interlocking plate 26 by the return force of the opening spring 29, and the rotating shaft 50 of the link 45 moves to the upper end of the elongated hole 44 of the seven frames 41.

Therefore, when the downward urging force of the interlocking plate 26 is released, the movable contact 27 also moves upward, and the contacts 36.75 are opened and separated. At this time, the drive bottle 34 is rapidly sucked downward, so that the lower end of the drive bottle 34 is attached to the movable contact 2.
7, apply a rotational force in the n1 direction to the movable contact 27, rotate the movable contact 27 at once, and
6.75 is opened. In addition, the display protrusion 26c can freely protrude from the display window 82 according to the vertical movement of the interlocking plate 26, and when the contacts 36 + 75 are open, the display protrusion 26c protrudes outward, and the contacts 36 and 75 are closed. When the display protrusion 26c does not protrude from the display window 82, the contact point 36.75
It is designed to display the opening and closing of the terminal.

Also, when an overcurrent flows, the bimetal 39 bends,
The screw 40 attached to the tip of the bimetal 39 presses against the back surface 53c of the latch engagement plate 53, rotates the latch engagement plate 53 half an hour in this direction about the pin 55, and the latch plate 48 of the engagement piece 57 is rotated half an hour in this direction. disengage with. , 2, the link 45 moves upward as in the previous case, the urging force on the interlocking plate 26 is released, and the contacts 36.75 are opened.

Next, after the trip operation, the knob 60 is in the on position, the display protrusion 26c protrudes, and by turning off the external switch SW2, the electromagnet section 3 is turned off and the movable iron core 7 is restored. By doing so, as shown in (11) in FIGS. 5 and 1, the connecting pin 18 is moved upward by the conversion shaft 11, and the link 45 is moved as shown. As shown in (c), the handle 60 is operated to the off position to return it to the off state.
0 is turned off and the connecting portion between the link 45 and the latch plate 48 is pressed downward by the pressing piece 68 of the handle 60.
By rotating the latch plate 48 in this direction by half an hour, the engagement recess 58 of the latch plate 48 and the engagement piece 57 of the latch engagement plate 53 can be engaged to perform resetting 7). At this time, since the auxiliary contact SWI is turned off by turning off the /) handle 60, the movable core 7 of the electromagnet section 3 returns to its initial position. Therefore, the reset is done by operating the handle 60 and the electromagnet part:
This can also be done by stopping the supply of voltage to the movable iron core 7 and returning the movable iron core 7 to its original position.

In this way, the movement of the movable core 7 of the electromagnet part 3 moves parallel to the bottom of the mounting base 1 and the bottom of the body 23, and the connecting bin 18 is moved out of the vertical direction via the conversion shaft 11. By completing the conversion, the operational impact of the electromagnet section 3 is not applied directly to the mounting base 1, and there is no adverse effect on other equipment. In addition, there is no vibration or shock in the contact opening/closing mechanism part B, which greatly improves reliability.Also, since the electromagnet part 3 moves in the lateral direction, the height of the remote control breaker can be lowered. is possible and can be made thin. In addition, it can be made into the same form as a general breaker, has a wide range of applications such as general-purpose parts, and can be operated at the same intervals as a combination of a breaker and an electromagnetic contactor. be.

[Effect 1 of the Invention As described above, the present invention has a contact 8 that opens and closes a contact inserted into the main circuit! A housing in which a plurality of electrodes are housed through a partition wall made of an insulating material, and a housing in which the contact mechanism is turned on when the handle is turned on to close the contact, and the contact is driven separately from the turn-off operation of the handle. A mounting base is provided in which an electromagnet part is housed and arranged to open the contact by driving the contact mechanism part off, and the mounting base is removably attached to one surface of the handle, and the contact mechanism part is driven to open the contact. Since the connecting member of the electromagnetic part that opens and closes is connected through a through hole drilled in the partition wall of the housing, there are 8 contacts! The structure part and the electromagnet part are connected through a connecting member, and the mounting base housing the electromagnet part can be detachably attached to the housing housing the contact mechanism part. This has the effect that the capacity of the contact mechanism section, that is, the capacity of the breaker, and the specifications of the electromagnet section can be changed quickly and easily. In addition, since the connecting member that connects the electromagnet part and the contact mechanism part is through a through hole drilled in the partition wall between the poles, even if the connecting member is used, it is not reliable, especially in terms of insulation.
