DETAILED DESCRIPTION

[0035] The utility model is further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 11 As shown, the intelligent control switch of the utility model includes a shell composed of a bottom shell 1 and an upper shell 2, a control board group 5 is arranged between the bottom shell 1 and the upper shell 2, and is characterized in that: the top of the bottom shell 1 is provided with N inlet terminal 6, L1 inlet terminal 7, L2 inlet terminal 8 and L3 inlet terminal 9 from left to right, and the bottom of the bottom shell 1 is provided with N outlet terminal 10, T1 outlet terminal 11, T2 outlet terminal 12 and T3 outlet terminal 13.

The end is connected with a connected guide rod 17, and the left closing electromagnet 14 and the right closing electromagnet 15 drive the connected guide rod 17 to move at the same time. A locking block 1701 is embedded in the connected guide rod 17, and the locking block 1701 acts on the locking slide 25, that is, when the connected guide rod 17 moves downward, the locking block 1701 also moves downward, and the locking block 1701 pushes the locking slide 25 to move right until the locking block 1701 is stuck in the groove of the locking slide 25. When the connected guide rod 17 moves downward, the micro switch 26 on the left will be toggled to close, and the control board group 5 will detect that the intelligent control switch is in the working closing state at this time and feedback to the display unit and the indicator light.

[0038] An opening electromagnet 27 is provided between the left closing electromagnet 14 and the right closing electromagnet 15. The iron core of the opening electromagnet 27 contacts the middle position of the head end of the conjoined guide rod 17. A opening guide rod 28 is also provided on the iron core of the opening electromagnet 27. The opening guide rod 28 acts on the locking slide 25. That is, when the opening electromagnet 27 is actuated, the opening guide rod 28 pushes the locking slide 25 to move rightward so that the locking block 1701 is disengaged from the groove of the locking slide 25. At this time, the conjoined guide rod 17 moves upward and resets under the action of the reset spring 245 pulling the lower armature 18. When the conjoined guide rod 17 moves upward and resets, the micro switch 26 on the left side loses control and disconnects. The control panel group 5 detects that the intelligent control switch is in the working opening state at this time and feeds back to the display unit and the indicator light.

[0039] The locking slide 25 is plugged into the locking plate pressure plate 29, and a return spring 30 is provided at the joint of the locking slide 25 and the locking plate pressure plate 29. When the locking block 1701 moves downward, the return spring 30 quickly rebounds and locks the locking block 1701 after the locking slide 25 moves to the right. The locking slide 25 moves back and forth in the direction of the locking plate pressure plate 29 plug-in interface. The locking plate pressure plate 29 is fixed on the bottom shell 1. A push rod 31 is provided at the left end of the locking slide 25. The push rod 31 is installed on the bottom shell 1 through a pressure plate. A switch dial button 32 is provided on the left end of the push rod 31. The switch dial button is fixedly installed on the upper shell 2 through two shaft sleeves 33. When the switch dial button 32 is manually pulled down, the locking slide 25 can be pushed to the right through the push rod 31. At this time, the connected guide rod 17 moves up, and the switch is disconnected and the power is cut off.

[0040] The lower end of the integrated guide rod 17 is connected to the moving head slide 16 through a spring, and the top of the moving head slide 16 is inserted into the integrated guide rod 17 through a lock 20. A moving contact 22 is provided on the moving head slide 16, and a static contact 23 is correspondingly provided below the moving contact 22. An arc extinguishing cover 24 is provided between the moving contact 22 and the static contact 23. When closing the circuit breaker, the moving contact 22 passes through the arc extinguishing cover 24 and contacts with the static contact 23. When opening the circuit breaker, the moving contact 22 is disconnected from the static contact 23.

[0041] The current transformer combination includes a metering current transformer 41 that can measure the amount of electricity in the power grid, a self-generated current transformer 42 that can provide power and measure overload and short-circuit currents, and a zero-sequence current transformer 43 that detects residual current in real time and performs leakage protection on the power grid, wherein the metering current transformer 41 is placed in the zero-sequence current transformer 43, the copper soft wire between the N input terminal 6 and the N output terminal 10 passes through the metering current transformer 41 and the zero-sequence current transformer 43, and the copper soft wire between the L1 input terminal 7, the L2 input terminal 8, the L3 input terminal 9 and the moving contact 22 passes through the metering current transformer 41, the self-generated current transformer 42 and the zero-sequence current transformer 43.

[0042] The bottom shell 1 is also provided with a battery 48 for providing working power for the control switch, a wiring terminal 49 for providing active and reactive meter calibration signal output and a 485 interface, and an external communication module interface 50 and a control board group 5 that comply with the Q / GDW1356-2013 standard, that is, an external power supply can be used, and the power generated by the self-generated current transformer of the intelligent control switch body can be used. The control board group is respectively connected to the battery 48, the left closing electromagnet 14 and the right closing electromagnet 15, the opening electromagnet 27, the external communication module interface 50, the metering current transformer 41, the self-generated current transformer 42, and the zero-sequence current transformer 43.

[0043] The upper end of the bottom shell 1 is provided with an upper cover 3 covering the N inlet terminal 6, L1 inlet terminal 7, L2 inlet terminal 8 and L3 inlet terminal 9, and the lower end is provided with a lower cover 4 covering the N outlet terminal 10, T1 outlet terminal 11, T2 outlet terminal 12 and T3 outlet terminal 13, and each of the upper and lower covers is provided with two lead sealing caps 51.

[0044] When in use, the closing electromagnet is energized. At this time, the integrated guide rod 17 moves downward to make the locking block 1701 slide into the groove of the locking slide 25, and the reset spring 30 rebounds quickly to lock the locking block 1701 in the groove of the locking slide 25. At this time, the moving contact 22 on the moving head slide 16 is tightly connected with the static contact 23, and the intelligent control switch is closed and energized; when the mutual inductor combination detection detects leakage or overload signals in the circuit through the control board group 5, a control command is issued to energize the opening electromagnet 27. At this time, the opening guide rod 28 pushes the locking slide 25 to move right, and the locking slide 25 loses the limit on the locking block 1701. At this time, the integrated guide rod 17 moves upward and resets, and the moving contact 22 on the moving head slide 16 is disconnected from the static contact 23, and the intelligent control switch is opened and powered off.

[0045] When the downstream circuit of the switch needs to be repaired or the power is cut off in an emergency, the switch knob 32 is manually dialed down to put the switch knob 32 in the off position. At this time, the knob pushes the top rod 31, and the top rod 31 pushes the locking slide 25 to the right, and the connected guide rod 17 moves up, and the moving contact 22 is separated from the static contact 23 to open the intelligent control switch and cut off the power; when the switch knob 32 is dialed down, the switch knob 32 will lose control of the micro switch 26, and the control board group 5 will detect that it is in the manual off state at this time and feedback to the display unit and the indicator light, and the control board group 5 will cut off the work The power supply prevents the closing electromagnet from being energized. In addition, an anti-misoperation structure is provided on the left side of the groove structure of the locking slide 25. When the switch dial 32 is in the opening position, the locking slide 25 moves to the right, so that the anti-misoperation structure is in the downward movement path of the locking block 1701 on the integrated guide rod 17. Even if the closing electromagnet is energized by mistake, the locking block 1701 cannot continue to move downward due to the obstruction of the anti-misoperation structure, and the switch cannot be closed. The microswitch and the misoperation structure on the locking slide 25 form a two-way electrical and mechanical safety guarantee to avoid danger during maintenance.

[0046] Except for the technical features described in the specification, the other technical features are known technologies to those skilled in the art.
