Description

[Technical Field] In particular, the electronic switch breaker with magnetic mechanism, remote-phone control system, keyboard, and software program such as a keyboard. The conventional circuit breaker uses mechanical, thermal-magnetic trip mechanism and other components. It can automatically cut off the circuit handle when a fault such as an incoming call occurs, so that the circuit is switched on again. The larger space inside the circuit breaker is relatively expensive, and the mechanical junction is faulty. When the failure occurs, the circuit breaker cannot be reset by hand to make the circuit breaker work again. , 4 remote daze and monitor. After the current short-circuit fault occurs, it is easy to cause the user with a fault. The short-circuit current is large when the second closing barrier is closed. The disconnection is very likely to cause physical damage to the user. In addition, for the protection of overload current, the bimetal is used to generate heat. Such energy-consuming and fragile metal pieces are more sensitive to temperature, and the accuracy and overload current of the Kun tube are all

The structure is to realize overload, short circuit and leakage of the circuit through the lever and transmission mechanism. After the fault is eliminated, the manual movement is required. With this design, the mechanical structure will occupy the circuit breaker and the structure cannot be reduced in size. Automatic recovery is prone to occur, and the user cannot use the conventional mechanical structure circuit breaker to enter. Because there is no mechanism locking function, it is extremely dangerous, because the arc generated by the circuit breaker contact with the relay is also very harmful. The protection is made of bimetallic piece or magnetic tubing alloy material. The metal piece will inevitably be damaged when the power is turned on. In a natural environment, the reliability is poor when the double temperature difference is large. However, the magnetic properties cannot be adjusted, the production process is complicated, and the process is complicated.

5. Description of the invention (2) The noise during operation is also large. It can be seen that the above-mentioned conventional circuit breakers still have many shortcomings and deficiencies. They are not a good designer and need to be improved. In view of the various shortcomings and deficiencies derived from the above-mentioned conventional circuit breakers, the inventor of this case has been eager to improve and innovate. After years of painstaking research, he has successfully developed and completed the electronic switch breaker with magnetic mechanism. [【 Content] This switchgear is simple to use the same power, and it will be in the state after failure. The mechanical structure cost will be sucked after the power is turned on. This will save the mechanism to ensure that the unmanufactured components can adapt to more telephone control. Compared with open circuit It is suitable for easy tripping. Therefore, the large lower iron coil saves the enamelled circuit breaker. It is a large-scale system. It is to provide a circuit breaker attached to a conventional circuit breaker. Compared with a volumetric device, the volume is approximately reduced and reliable. In the case of overload and overload, the fault will be operated remotely; the mechanical mechanism itself will be removed and it is easy to use; the power will be cut off and the magnetic mechanism will keep the energy consumption when the line is energized, and the arc will be limited after the short circuit fault. The only difference is the temperature difference that maintains high power under the elimination of fault product and weight; the present invention will make the system have a group The simple magnetic mechanism will be greatly doubled, and after the leakage and open circuit are eliminated, the complex and self-improving machinery will bring the circuit breaker to the circuit breaker to eliminate the noise and make the circuit breaker before closing; To ensure that the Gongming circuit breaker should be low in cost and electronically open and small, which is commensurate with or inferior to the inertia structure, the failure of the occupied space will be restored. Therefore, the main circuit is connected to work, and the locked closing is reliable with this current control. The electronic switch with magnetic mechanism is used for remote and multi-function to achieve the purpose of the invention. The movable copper and moving silver points on the movable shaft in the middle of the button or switch handle correspond to the positions inside the casing. The left fixed copper on the right and the static silver 2 on the right fixed copper correspond to each other. A magnetic mechanism can be set between the left fixed copper and the right fixed copper. The middle of the sex mechanism is a permanent magnet, and the two sides of the permanent magnet are two iron core plates. One of the iron core plates is provided with a coil bobbin, and the coil frame is wound with an enameled coil, and the coil is connected to the CPU. The other iron core plate is wound with a main circuit wire 丄, and a copper wire is also provided under the movable copper. Another static magnet is connected to the CT string on the main circuit of the electric copper. The static magnet is above the moving magnet. One end of the pull rod is in the position of the moving line of the moving magnet. The other end of the pull rod is connected to the card. One end of the card is connected to the card reset spring. The other end is in contact with the movable shaft. The circuit breaker of the present invention also includes a trip unit and a current adjustment block. The CT signal is amplified, sampled, pre-amplified, and power amplified by the electronic circuit to the trip unit. The CT And the electronic circuit board are arranged in a casing; the circuit breaker of the present invention can be combined with a telephone, a voice system, a keyboard, a software program, etc. to form a remote telephone control system, and the voice system and the telephone control part transmit the processing to the open circuit. CPU circuit board in the controller, the CPU circuit board controls the output to connect the magnet coil of the circuit breaker, the circuit breaker's incoming copper is connected to the mains, and to the electrical appliance. € Net [implementation method] Please refer to Figures 1 and 2 for the schematic diagram of the magnetic mechanism and the specific structure of the electronic circuit breaker with magnetic mechanism of the present invention. It can be seen in 2 openings that an automatic button is installed on the outside of the casing 3. i (also known as ^ 关 把 f 'The middle of the automatic button 1 is the movable shaft 2, which is covered with a reset spring yellow

During operation, the iron suction coil 7 4 Before the power is turned off, the permanent magnet 7 3 cannot attract the moving iron core block 6 on the movable copper 4 because the distance is far, and the movable shaft 2 does not move. Therefore, the automatic button 1 is not down, and the motion on the movable copper 4 is not moved. Point 9 is not in contact with the static silver point 5 corresponding to the up and down position, so the mains power is not turned on, and the circuit breaker does not work. When the line of the suction coil 74 receives the instruction of the CPU, the line of the suction coil 74 is switched on. The iron suction coil 74 is energized (assuming a positive direction), and the iron core plate 7 1 generates magnetic force, attracts the moving iron core block 6 on the movable copper 4 and passes the movable shaft 2 to overcome the pulling force of the reset spring on the automatic button 1 and goes downward. So that the moving silver point 9 and the static silver point 5 contact the mains and the circuit breaker works; after the circuit breaker is turned on, the CPU issues a command to close the line of the iron suction coil 74, so that the iron suction coil 74 is not energized. If the iron core block 7 1 loses its magnetism, it will not be able to attract the moving iron core block 6, but because the moving iron core block 6 TIm A 4 iron 7 3 is close, the permanent magnet 7 3 will attract
