DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] See also Figure 1-Figure 16 , the present invention provides a technical solution:

[0054] An intelligent circuit breaker capable of remotely controlling the opening and closing of a circuit breaker by a mobile phone comprises a control terminal 1 and a circuit breaker housing 2. A circuit breaker mechanism is arranged inside the circuit breaker housing 2 to realize the opening and closing operation of the circuit breaker, and the control terminal 1 realizes the control operation of the circuit breaker mechanism through a remote control system, and the circuit breaker mechanism comprises:

[0055] An overcurrent protection unit 3 is arranged inside the circuit breaker housing 2 and connected to the upper terminal of the circuit breaker, and implements control operation when encountering an overcurrent condition;

[0056] The overvoltage protection unit 4 is arranged inside the circuit breaker housing 2 and connected to the lower terminal of the circuit breaker, and implements control operation when encountering an overvoltage situation.

[0057] The arc extinguishing unit 5 includes an arc extinguishing chamber 51, and a smooth arc extinguishing electrode 52 is installed below the arc extinguishing chamber 51, and the bottom end of the arc extinguishing electrode 52 is connected to an upper metal sheet 53 through a connecting unit 6, and the upper metal sheet 53 is electrically connected to the overcurrent protection unit 3 and the overvoltage protection unit 4 when the circuit breaker is closed, and the rotation operation of the upper metal sheet 53 is completed by the operating mechanism 7, and the extending end of the upper metal sheet 53 is provided with an extension piece 54.

[0058] By providing a circuit breaking mechanism, when an overcurrent or overvoltage operation occurs, the overcurrent protection unit 3 and the overvoltage protection unit 4 are used to realize automatic control of the circuit breaker to complete the opening operation, and the upper metal sheet 53, the contact plate 65, the connecting sheet 64, the connecting plate 61 and the arc extinguishing electrode 52 form a connected transmission surface to complete the guiding and removal operation of the instantaneous arc, thereby effectively improving the safety of the circuit breaker and solving the safety hazards caused by the arc. At the same time, it avoids the problem that the arc cannot be introduced into the arc extinguishing chamber due to the gap or detachment caused by the rotation of the metal sheet.

[0059] See also Figure 3-Figure 5 , the overcurrent protection unit 3 includes:

[0060] The frame 31 is installed above the inside of the circuit breaker housing 2, and a cylindrical iron core 32 is slidably provided through the inner space and the bottom side of the frame 31, and an electromagnetic coil 33 is evenly wound on the surface of the cylindrical iron core 32;

[0061] The stationary contact 34 is installed on the bottom side of the frame 31 , and the upper terminal of the electromagnetic coil 33 is electrically connected to the upper terminal, and the lower terminal of the electromagnetic coil 33 is electrically connected to the end of the stationary contact 34 .

[0062] Among them, the cylindrical iron core 32 is composed of a thick cylinder and a push rod, the push rod and the frame 31 penetrate and slide, and a return spring is sleeved on the surface of the push rod, and the end of the return spring is fixed to the opposite side of the thick cylinder and the frame 31, so as to realize the downward movement operation of the cylindrical iron core 32 when overcurrent occurs.

[0063] When an overcurrent occurs, the current will increase several times, causing the electromagnetic coil 33 to produce an electromagnetic reaction and drive the cylindrical iron core 32 to move downward. The cylindrical iron core 32 resists the rotation of the control frame 71, thereby realizing the power-off operation. At this time, the arc generated by the power-off will be transmitted to the arc extinguishing chamber 51 along a connected transmission surface formed by the upper metal sheet 53, the contact plate 65, the connecting plate 64, the connecting plate 61 and the arc extinguishing electrode 52 for segmentation processing until it is eliminated.

[0064] See also Figure 7 , the overvoltage protection unit 4 includes:

[0066] The lower bracket sheet 42 is fixed to and electrically connected to the lower metal sheet 41 , and the end of the lower bracket sheet 42 is electrically connected to the lower terminal.

[0067] When overvoltage occurs, the temperature of the lower metal sheet 41 will increase until it exceeds the threshold, causing it to bend and press the lever 68 downward. At this time, the lever 68 drives the control frame 71 to rotate to achieve the power-off operation. At this time, the arc generated by the power-off will be transmitted along the upper metal sheet 53, contact plate 65, connecting plate 64, connecting plate 61 and arc extinguishing electrode 52 to form a connected transmission surface and be transmitted to the arc extinguishing chamber 51 for segmentation processing until it is eliminated.

[0068] See also Figure 5-Figure 6 , the operating mechanism 7 comprises:

[0069] The control frame 71 is rotatably mounted inside the circuit breaker housing 2 via a support shaft, and a moving contact is mounted on the side opposite to the upper metal sheet 53, while a pulling assembly 72 is disposed on the lower side of the control frame 71 and the lower side of the upper metal sheet 53;

[0070] The handle 73 is rotatably mounted inside the circuit breaker housing 2 and the toggle portion extends to the outer shell of the circuit breaker housing 2. The handle 73 is connected to the control frame 71 through a convex ring 74, and the convex ring 74 and the handle 73 are rotatably mounted. The convex ring 74 moves in a groove set at the tail of the control frame 71, and a curved spring 76 is installed at a convex column 75 located on the surface of the convex ring 74 and the side of the frame 31.

[0071] See also Figure 6 , the pulling assembly 72 includes:

[0072] The I-shaped ring 721 rotates with the middle extension of the bottom of the upper metal sheet 53 on one side, and moves in contact with the bottom of the control frame 71 on the other side;

[0073] The telescopic spring 722 is sleeved in the middle of the I-shaped ring 721 , and one side of the telescopic spring 722 is in contact with the bottom of the control frame 71 to realize the operation of pressing the telescopic spring 722 when the I-shaped ring 721 and the upper metal sheet 53 rotate relative to each other.

[0074] See also Figure 7-Figure 10 and Figure 12-16 , the connection unit 6 comprises:

[0075] The connecting plate 61 is connected and fixed to the bottom of the arc-extinguishing electrode 52, and a wrapping block 62 is installed at the rear side of the connecting plate 61, and the end of the upper metal sheet 53 rotates with the inner wall of the wrapping block 62, and the connecting plate 61 is connected with a connecting piece 64 through a sliding component 63, and a contact plate 65 is rotatably installed inside the connecting plate 61, and the bottom side of the contact plate 65 is always in close contact with the top surface of the upper metal sheet 53, and the surface of the contact plate 65 is slidable on the top surface of the upper metal sheet 53 through a moving component 66, and a balancing component 67 is provided on the side of the connecting piece 64 close to the contact plate 65 to control the position of the connecting piece 64;

[0076] The lever 68 passes through the control frame 71 and can slide relative to the control frame 71 , and the lever 68 rotates between the extension member 54 . Meanwhile, a baffle 69 is installed at the bottom end of the lever 68 , and the baffle 69 contacts the end of the lower metal sheet 41 .

[0077] By providing a connecting unit 6, when the upper metal sheet 53 rotates, the L-shaped plate 661 and the movable column 662 move in the movable groove 663, so that the contact plate 65 is located on the top surface of the upper metal sheet 53 and moves and maintains continuous contact with the upper metal sheet 53. The direction of the contact plate 65 changes, and the connecting plate 64 moves downward so that the bottom edge of the connecting plate 64 contacts the right side surface of the contact plate 65 or the top surface of the upper metal sheet 53, thereby realizing that the upper metal sheet 53, the contact plate 65, the connecting plate 64, the connecting plate 61 and the arc extinguishing electrode 52 form a connected transmission surface, which can not only avoid the pulling generated when the upper metal sheet 53 rotates, but also maintain a continuous electrical transmission surface between the upper metal sheet 53 and the arc extinguishing electrode 52, thereby improving the smoothness and safety of arc guiding.

[0078] See also Fig.15 The sliding assembly 63 includes a slider 631 symmetrically fixedly mounted on the connecting piece 64, and a slide groove 632 adapted for sliding of the slider 631 is provided on the inner side of the connecting plate 61 and in contact with the connecting piece 64, and the sliding of the slider 631 in the slide groove 632 realizes the vertical movement operation of the connecting piece 64.

[0079] A return spring may be installed on the top of the slider 631 and the opposite side of the slide groove 632 to provide downward force for the slider 631 .

[0080] See also Figure 13-14 The moving component 66 includes an L-shaped plate 661 symmetrically installed on both sides of the contact plate 65, and symmetrical moving columns 662 are respectively installed on the opposite sides of the L-shaped plate 661. A moving groove 663 adapted to accommodate the movement of the moving column 662 is opened on the side opposite to the upper metal sheet 53, and the moving column 662 moves inside the moving groove 663 to realize the movement of the contact plate 65 located on the top surface of the upper metal sheet 53 and maintain continuous contact with the upper metal sheet 53.

[0081] See also Figure 15-16 The balancing assembly 67 includes a balancing sheet 671, a placement slot 672 is provided on one side of the connecting sheet 64 close to the contact plate 65, and the balancing sheet 671 is rotated at the lower side of the placement slot 672, and an arc spring 673 is installed between the balancing sheet 671 and the placement slot 672 to drive the balancing sheet 671 to rotate.

[0082] When the upper metal sheet 53 is higher on the right side and lower on the left side, the balancing sheet 671 on the connecting sheet 64 contacts the right side surface of the contact plate 65. Otherwise, the balancing sheet 671 on the connecting sheet 64 directly contacts the top surface of the upper metal sheet 53, and the bottom edge of the connecting sheet 64 also directly contacts the top surface of the upper metal sheet 53.

[0083] See also Fig.11 , the extension member 54 comprises:

[0084] The extension plate 541 is provided with a rotating rod 542 fixed at the groove of the extension plate 541, and the rotating rod 542 and the lever 68 are intersected and rotated;

[0085] An extension groove 543 is provided at the extension of the bottom surface of the upper metal plate 53, and the extension plate 541 slides inside the extension groove 543, and sliding bars 544 are installed on both sides of the extension plate 541, and a horizontal groove 545 adapted to the sliding of the sliding bar 544 is provided on the opposite side of the extension groove 543.

[0086] By providing the extension piece 54, whether the rotation of the control frame 71 is realized by automatic control or the rotation of the control frame 71 caused by overcurrent and overvoltage, the upper metal sheet 53 will rotate accordingly, thereby avoiding the problem that the relative rotation between the upper metal sheet 53 and the control frame 71 will generate tension and cause the upper metal sheet 53 to be pulled or bent, making the operation of the circuit breaker smoother, safer, and more convenient.

[0087] The remote control system includes a mobile phone terminal and a wireless transmission module, and the wireless transmission module transmits the instructions of the mobile phone terminal to the control terminal 1 through the 5G network, and uses the control terminal 1 to drive the handle 73 in the circuit breaker housing 2 to perform opening and closing operations.

[0088] By setting up a remote control system, the mobile phone is used to generate control instructions for the circuit breaker, and the instructions are transmitted based on the 5G network transmitted between the mobile phone and the circuit breaker. After the instructions are received by the control terminal 1, the handle is controlled to complete the opening or closing operation.

[0089] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0090] When working, the mobile phone or control panel is used to transmit the command, and then the command is transmitted to the control terminal 1 through the wireless transmission module to control the opening and closing operation of the handle 73 in the circuit breaker;

[0091] When the handle 73 is closed downward, the convex ring 74 drives the control frame 71 to rotate, and the control frame 71 drives the extension of the curved spring 76, and the I-shaped ring 721 drives the compression of the telescopic spring 722, and the moving contact on the control frame 71 presses the upper metal sheet 53 to rotate, and the upper metal sheet 53 is separated from the static contact 34, thereby completing the upper side electrical separation operation;

[0092] During the rotation of the upper metal sheet 53, the extended end of the upper metal sheet 53 rotates between the extension plate 541 and the lever 68, and the sliding bar 544 slides in the horizontal groove 545 to make the extension plate 541 move along the extension direction of the metal sheet, and the lever 68 also moves downward accordingly;

[0093] While the upper metal sheet 53 rotates, the L-shaped plate 661 and the moving column 662 move in the moving groove 663, so that the contact plate 65 located on the top surface of the upper metal sheet 53 moves and maintains continuous contact with the upper metal sheet 53. At the same time, as the direction of the contact plate 65 changes, the connecting piece 64 moves downward so that the bottom edge of the connecting piece 64 contacts the right side of the contact plate 65 or the top surface of the upper metal sheet 53, thereby realizing that the upper metal sheet 53, the contact plate 65, the connecting piece 64, the connecting plate 61 and the arc-extinguishing electrode 52 form a connected transmission surface;

[0094] When an overcurrent occurs, the current at this time will increase several times, causing the electromagnetic coil 33 to produce an electromagnetic reaction and drive the cylindrical iron core 32 to move downward, and the cylindrical iron core 32 pushes the control frame 71 to rotate, thereby realizing the power-off operation. At this time, the arc generated by the power-off will be transmitted to the arc extinguishing chamber 51 along a transmission surface formed by the upper metal sheet 53, the contact plate 65, the connecting sheet 64, the connecting plate 61 and the arc extinguishing electrode 52 to be segmented and processed until it is eliminated;

[0095] When overvoltage occurs, the temperature of the lower metal sheet 41 will increase until it exceeds a threshold value, causing it to bend and press the lever 68 downward. At this time, the lever 68 drives the control frame 71 to rotate to achieve a power-off operation and simultaneously complete the arc removal operation.

[0096] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
