However, in the design as described above, the space that the machine structure occupies in the breaker is large, the volume of the breaker is relatively large and the cost is high, and the disadvantage of the machine structure body is that it lacks stability and is prone to failure. I can say. If such a breaker breaks down, the user must set it again to work normally, and there is also the inconvenience that the remote control cannot be operated.
In addition, even after a failure due to a short circuit, there is no lock function, so even if the breaker fails, a current is applied and the current increases and the arc becomes larger, causing secondary damage and putting the user at risk. Will be.
Protection against overload current is protected by a bimetal piece or magnetic oil pipe, but the bimetal piece is made of an alloy material and generates heat when energized, so energy consumption and damage cannot be avoided. However, there is also a problem that it is sensitive to temperature and is likely to cause abnormality when the temperature difference is large.

The other end of the lever is connected to the fitting part, and a spring is connected to one end of the fitting part. The other end of the fitting portion is brought into contact with the movable shaft, and further, a releaser and a current adjustment block are provided, and the CT signal passes through shaping amplification, sampling adjustment, preamplification, and power amplification of the electronic circuit to the releaser. The CT and the electronic circuit board are housed in one outer shell, and the telephone, voice system and keyboard, and a remote control system by telephone is configured by a software program, etc., and the remote control part by the voice system and telephone The signal processed in step 1 is transmitted to the CPU circuit in the breaker, the CPU circuit board outputs the signal to the coil of the breaker, and the input end of the breaker is connected to general electricity such as a house. Connect the end to electrical equipment.

  According to the present invention, it offers many advantages such as small volume, simple structure, low cost and easy maintenance, and at the same time, it has succeeded in providing a highly practical breaker that combines a remote control function with a telephone. did.

  As shown in FIGS. 1 and 2, the present invention has an outer shell 3, and a manual button 1 (or switch lever) is provided on the outer shell 3, and the middle of the manual button 1 is a movable shaft 2. A recovery spring 39 is provided on the movable shaft 2, and a lower end of the movable shaft 2 is located in the outer shell 3 and is coupled to the movable copper piece 4. A movable iron core block 6 is connected to the middle section. In the outer shell 3, there are provided stationary silver contacts 5 corresponding to the movable silver contacts 9 provided at both ends of the lower surface of the movable copper piece 4. Connected. A magnetic structure 7 is provided at an intermediate position in the outer shell 3, and the magnetic structure 7 includes an iron core plate 71, a coil rack 72, a permanent magnet 73 and a coil 74, and the two iron core plates. 71 is pure iron. A permanent magnet 73 is provided between the two iron core plates 71, and a coil rack 72 is provided on an upper stage of any of the two iron core plates 71, and is wound around the iron core plate 71. An enameled wire 74 is wound thereon, and the opening and closing of the coil 74 circuit is controlled by the CPU circuit board 10.

Before the coil 74 is energized, the permanent magnet 73 cannot attract the movable iron core block 6 on the movable copper piece 4, the movable shaft 2 does not move, and the manual button 1 is not in the lowered position. Since the movable silver contact 9 on the movable copper piece 4 and the corresponding stationary silver contact 5 are not in contact with each other and are in a non-energized state, the breaker is not yet operated and is not in an energized state. When the circuit of the coil 74 is closed in response to a command from the CPU and becomes conductive with a positive polarity, the iron core plate 71 generates a magnetic force to attract the movable iron core block 6 on the movable copper piece 4, and the movable shaft 2 descends against the spring on the manual button 1, the movable silver contact 9 and the stationary silver contact 5 come into contact with each other, and a power source is energized from a commercial power source to be in an energized state.
After the breaker enters the operating state, the circuit of the coil 74 is opened by a command from the CPU, the coil 74 is deenergized, the iron core plate 71 loses magnetic force and attracts the movable iron core block 6. Although it becomes impossible, since the movable iron core block 6 is close to the permanent magnet 73 in the lowered position, the movable iron core block 6 is attracted by the magnetic force of the permanent magnet 73 and the stationary silver contact 5 is in an energized state. The breaker will continue to operate.
When a fault such as overload, short circuit, electric leakage, or damage is detected, the CPU issues a command and the coil 74 circuit is energized. In this case, it is energized with the opposite polarity to the original polarity. The iron core plate 71 generates magnetism opposite to that described above, the magnetic force of the permanent magnet 73 against the movable iron core block 6 is canceled and the movable iron core block 6 is not attracted, and due to the repulsive force of the recovery spring, The movable copper piece 4 on the movable shaft 2 and the iron core block 6 thereon are repelled upward, the movable silver contact 9 and the stationary silver contact 5 are separated, the current is cut off, and the breaker is not activated. It becomes a state. When it returns to a normal state due to repair or the like, the breaker continues to enter the operating state and the above-described operation is repeated.

As shown in FIGS. 3 and 4, in the structure of the present invention, when the breaker is dropped, the movable copper piece 4 is positioned above, and the movable silver contact 9 and the stationary silver contact 5 at both ends are separated from each other. Therefore, the input end 24 is in a state where the circuit leading to the output end 23 through the copper conductor 22, the stationary silver contact 5, the movable silver contact 9, and the main circuit conductor 16 is cut off, and the breaker is inactivated.
When the breaker is operating normally, the lock bar 17 is in the lowered position, the notch 20 on the lock bar 17 reaches the position of the fitting portion 12, and the fitting portion 12 The fitting part 12 and the lever 11 are engaged with each other by being fitted into the notch 20 by the action. The lever 11 has a rotation axis point (on the breaker). Therefore, the other end of the lever 11 rotates in a clockwise direction, and the movable magnet 14 is pushed up to the position of the broken line in FIG. 15 is separated.
In this state, the switch body 19 is in the lowered position against the repulsive force of the spring, and the movable copper piece 4 brings the movable silver contact 9 on both ends thereof into contact with the stationary silver contact 5 on the lower surface, thereby The input end 24, the copper conductor 22, the stationary silver contact 5, the movable silver contact 9, and the main opening conductor 16 energize the main circuit of the output end 23 to bring the breaker into an operating state.
At this time, the permanent magnet in the magnetic structure 7 attracts the movable iron core block 6 to energize the stationary silver contact, and the copper conductor 22 is constant when the breaker on the iron core plate is operating normally. However, since it is within the range that clears the set value of the copper conductor 22, the action of the magnetic force due to the current during normal operation need not be taken into consideration. The magnetic force generated in the main circuit conductor 16 does not act on the movable magnet 14.
When a short circuit occurs in the main circuit, a very large current flows through the entire circuit, and the copper conductor 22 and the iron core plate generate a huge magnetic force between the permanent magnet 73 and the movable iron core block 6. The magnetic force of the reverse polarity caused by the magnetic field cancels the magnetic force that the permanent magnet 73 attracts the movable core block 6, the switch body 19 is pushed upward by the action of the recovery spring, the stationary silver contact is released, and the main circuit is disconnected. The breaker will not operate.
At the same time, when the short circuit occurs, the main circuit conductor 16 generates a large magnetic force, the movable magnet 14 and the stationary magnet 15 attract each other, rotate the lever 11 counterclockwise, and connect to the other end of the lever 11. The fitting portion 12 that moves away the lock bar 17 from the notch 20, and the lock bar 17 jumps upward by the action of the tension spring 18.

As shown in FIGS. 5 and 6, the CT becomes a current sensing unit 25, and the sensed signal is input to the electronic circuit 26, and after passing through the preamplification, shaping amplification, power amplification, and sampling adjustment, it reaches the releaser 27. The rectified filtering that is output and output by the current sensing unit 25 reaches each part of the electronic circuit 26 described above.
As shown in FIG. 7, the circuit board of the electronic circuit 26 and the current sensing unit 25 are accommodated in one outer shell, and the overload current value sensed by the current regulation block 28 is adjusted.
When working normally, the current is not overloaded. When the current is overloaded, the current sensing unit 25 senses the overload current from the wire of the main circuit line perforation 29, and the signal is It is sent to the electronic circuit 26, and after pre-amplification, shaping amplification, power amplification, and sampling adjustment, it is further output to the releaser 27. The releaser 27 releases the current in the breaking circuit and breaks the electric device. Protect from getting to.

The remote control system is provided to control the electric appliance 36, and the telephone input line 31 of the telephone 30 is connected to the telephone control module 33, the voice system, the keyboard 37, and the display monitor 38, and the output is The CPU circuit board 10 in the breaker 34 is connected to the CPU circuit board 10 to control the enamel wire 74, the input of the magnetic structure breaker is connected to the electric appliance 35 in a general house, and the output is connected to the electric appliance 36. Connect (refer to the broken line in the figure for the end).

  When a telephone call is received, if the electric appliance 36 is to be operated by remote control as shown in FIG. 8, the password is first input and the program is processed in order, but the electric appliance is turned on. The voice system and telephone control module 33 outputs the signal to the CPU circuit board 10 in the breaker 34. The CPU circuit board 10 energizes the enamel wire 74, sucks the movable iron core block 6, brings the movable silver contact 9 on both ends and the stationary silver contact 5 on the lower surface into contact with each other, and the input end 24 The iron 22, the stationary silver contact 25, the copper silver contact 9, and the main circuit conductor 16 are energized to the main circuit of the output end 23, the electric device controlled by the breaker is turned on, and when the breaker is energized, The CPU circuit board 10 in the breaker issues a command again, disconnects the circuit of the enameled wire 74, and the enameled wire 74 is turned off. Accordingly, the iron core block 71 loses its magnetism and the movable iron core block 6 cannot be attracted, the movable iron core block 6 is lowered and approaches the permanent magnet 73, and the permanent magnet 73 attracts the movable iron core block 6. . When trying to turn off the electric device, the software program is processed in the same manner, and the voice system and the telephone control module 33 output a signal to the CPU circuit board 10 in the breaker 34. The circuit board 10 energizes the coil 74 circuit. However, since the power source in the negative direction opposite to the original direction is supplied, the iron core 71 is magnetized in the opposite direction. The magnetic force of the permanent magnet 73 to the movable core block 6 is canceled, the movable core block 6 is not attracted, and the movable shaft 2 is moved to the movable copper piece 4 and the movable core of the plant by the elasticity of the recovery spring. The block 6 is flipped upward, the movable silver contact 9 and the stationary silver contact 5 are separated from each other, the breaker is not operated, and the electric device is turned off.
