[0033] The present invention provides an outdoor pole-mounted large-capacity high-voltage circuit breaker.

[0034] like Figures 1 to 3 The outdoor pole-mounted large-capacity high-voltage circuit breaker shown includes a controller, a handheld terminal 4, a connecting cable 41, a junction box 5, a pushing mechanism 2 and a circuit breaker body 1. The pushing mechanism 2 is arranged on the outside of the circuit breaker body 1, and the output end of the pushing mechanism 2 is connected to the handle 11 of the circuit breaker body 1. The pushing mechanism 2 is used to push the handle 11 so that the handle 11 controls the circuit breaker body 1 to open and close. The controller is arranged on the junction box 5, and a connecting socket 53 is provided on the outside of the junction box 5. The connecting socket 53 is electrically connected to the controller. The junction box 5 is used to be arranged at a lower position on the pole; one end of the connecting cable 41 is connected to the handheld terminal 4, and the other end of the connecting cable 41 is detachably connected to the connecting socket 53. The handheld terminal 4 is used to send a control signal to the controller by inserting the connecting cable 41 into the connecting socket 53; the controller is electrically connected to the pushing mechanism 2, and the controller is used to receive the control signal and control the pushing mechanism 2 according to the control signal to open and close the circuit breaker body 1.

[0035] A junction box 5 is set at a lower position of the pole, and a pushing mechanism 2 is set outside the circuit breaker body 1. The staff uses a connecting cable 41 to connect the handheld terminal 4 and the junction box 5, and then controls the pushing mechanism 2 through the handheld terminal 4 to drive the handle 11 to swing, thereby controlling the opening and closing of the circuit breaker body 1. This saves the staff from having to climb to the top of the pole to manually open and close the circuit breaker, making it convenient for the staff to use.

[0036] Specifically, the handheld terminal 4 is used to separately connect multiple junction boxes 5, so that the handheld terminal 4 can control multiple driving mechanisms 2. The one-to-many use of the handheld terminal 4 can reduce the cost of use. One handheld terminal 4 can only control one driving mechanism 2 at a time.

[0037] Specifically, a storage space 51 is provided within the junction box 5, which is also provided with an electrical control cover 52. A connection socket 53 and a controller are both provided within the storage space 51. An identification port (not shown) is provided on the side of the electrical control cover 52 facing away from the storage space 51. A control panel 42 is provided on one side of the handheld terminal 4, and a display window (not shown) is provided on the other side of the handheld terminal 4. The control panel 42 is electrically connected to the connection cable 41, and the display window is used to display an identification code. The controller is electrically connected to the identification port and the electrical control cover 52, respectively. The identification port is used to obtain the identification code displayed in the display window and transmit it to the controller, which is used to control the opening of the electrical control cover 52 based on the identification code. This improves the safety performance of the junction box 5.

[0038] The outdoor pole-mounted high-capacity high-voltage circuit breaker also includes a housing 3, which is fixed to the outside of the circuit breaker body 1 and is used to accommodate the handle 11 and the driving mechanism 2. The provision of the housing 3 can prevent the driving mechanism 2 from being exposed to the outside for a long time and protecting it from erosion by wind and rain.

[0039] The pushing mechanism 2 includes an electric screw 21 and a connecting structure 22. The slide of the electric screw 21 is used to articulate the rotating handle 11 through the connecting structure 22. The electric screw 21 is used to drive the moving path of the connecting structure 22 to be parallel to the swinging path of the rotating handle 11. The controller is electrically connected to the electric screw 21, and the controller is used to control the electric screw 21 to drive the connecting structure 22 to move, so that the connecting structure 22 drives the rotating handle 11 to swing.

[0040] Specifically, the height of the electric screw 21 is lower than that of the handle 11. Due to the internal structure of the circuit breaker body 1, the handle 11 can only be located in the middle position of the outer side of the circuit breaker body 1. Considering the stroke and the thrust of pushing the handle 11, the electric screw 21 does not need to change the external structure of the circuit breaker body 1, and can meet the thrust of pushing the handle 11.

[0041] Specifically, the connecting structure 22 is located between the electric screw 21 and the handle 11

[0042] The connecting structure 22 includes an insulating vertical column 23, an insulating rod 24, a first hinge axis and a second hinge axis. The insulating vertical column 23 is arranged vertically, and the slide drive of the electric screw 21 is connected to one end of the insulating vertical column 23; the insulating vertical column 23 is away from one end of the electric screw 21 and one end of the insulating rod 24, and is hinged through the first hinge axis; the other end of the insulating rod 24 is used to be hinged to the turning handle 11 through the second hinge axis; the first hinge axis and the second hinge axis are parallel and spaced apart, and the first hinge axis and the second hinge axis are both arranged horizontally, and the first hinge axis and the second hinge axis are both perpendicular to the moving path of the insulating vertical column 23; the controller is electrically connected to the electric screw 21, and the controller is used to control the electric screw 21 to drive the insulating vertical column 23 to move, so that the insulating vertical column 23 drives the turning handle 11 to swing through the insulating rod 24.

[0043] An insulating plate 31 is disposed transversely within the housing 3. This plate defines a rectangular through-hole 32, extending along the path of movement of the insulating upright 23. The insulating plate 31 divides the interior of the housing 3 into an operating space 33 and an installation space 34. The electric screw 21 is positioned within the installation space 34, with its slide directly facing the rectangular through-hole 32. The insulating rod 24, the first hinge axis, and the second hinge axis are all positioned within the installation space 34, which also accommodates the handle 11. The insulating upright 23 extends through the rectangular through-hole 32. The provision of the insulating plate 31 can mitigate the risk of leakage current from the circuit breaker body 1 affecting the electric control screw.

[0044] Specifically, two insulating elastic layers (not shown) are disposed within rectangular through-hole 32. One insulating elastic layer, insulating upright post 23, and the other insulating elastic layer are sequentially connected. One end of one insulating elastic layer, away from insulating upright post 23, is connected to one end of rectangular through-hole 32, while the other end of the other insulating elastic layer, away from insulating upright post 23, is connected to the other end of rectangular through-hole 32. These two insulating elastic layers serve to isolate installation space 34 from workspace 33.

[0045] Specifically, a connecting seat 25 and a limiting screw 26 are arranged between the insulating vertical column 23 and the slide of the electric screw 21. The connecting seat 25 is fixed to the slide of the electric screw 21. A receiving hole (not shown in the figure) is provided on the side of the connecting seat 25 close to the insulating plate 31. The receiving hole is used to accommodate the end of the insulating vertical column 23 away from the working space 33; a screw hole is provided in the horizontal direction at the end of the insulating vertical column 23 away from the working space 33 (not shown in the figure), and two limiting through holes are provided in the horizontal direction on the connecting seat 25 (not shown in the figure). The two limiting through holes are symmetrically arranged along the insulating vertical column. The limiting screw 26 is used to, when the insulating vertical column 23 is inserted into the receiving hole, one end of the limiting screw 26 passes through one of the limiting through holes, the threaded connection screw hole and the other limiting through hole in sequence, so as to fix the relative positions of the insulating vertical column 23 and the connecting seat 25.

[0046] Specifically, an insulating handle 27 is provided on the side of the insulating post 23 away from the circuit breaker body 1, and the insulating handle 27 is located within the installation space 34. If the electric screw 21 loses control, the operator can withdraw the limit screw 26 to separate the insulating post 23 from the connecting shaft 25. The operator then pushes the insulating post 23 along the rectangular through hole 32 to control the swing of the handle 11. This not only controls the swing of the handle 11, but also provides insulation protection for the insulating rod 24, insulating post 23, and insulating handle 27, preventing electric shock from direct contact with the handle 11.

[0047] A first door 35 and a second door 36 are provided on one side of the housing 3, away from the circuit breaker body 1. The first door 35 is used to open and close the work space 33, while the second door 36 is used to open and close the installation space 34. The provision of the first and second doors 35, 36 facilitates maintenance of the connecting structure 22 and the electric screw 21.

[0048] A display structure 6 is provided on the side wall outside the housing 3, away from the circuit breaker body 1. A connecting structure 22 drives and connects to the display structure 6. The display structure 6 is used to display the closed or open state of the circuit breaker body 1. The connecting structure 22 is used to drive the display structure 6 to display the closed state when the handle 11 is driven to close the circuit breaker body 1, or to drive the display structure 6 to display the open state when the handle 11 is driven to open the circuit breaker body 1. The provision of the display structure 6 allows workers to intuitively determine the current closed or open state of the circuit breaker body 1 without having to climb to the top of the pole.

[0049] Specifically, the display structure 6 is located between the first door body 35 and the second door body 36 .

[0050] The display structure 6 includes a slider 61 and a connecting column 62, as well as marking layers 63 provided at both ends of the slider 61. One marking layer 63 is used to indicate that the circuit breaker body 1 is in the closed state; the other marking layer 63 is used to indicate that the circuit breaker body 1 is in the open state. A receiving groove 37 is provided on the side wall of the working space 33 away from the circuit breaker body 1. The receiving groove 37 extends along the movement direction of the connecting structure 22. Two marking openings 38 are provided on the outer wall of the box body 3, one of which is connected to one end of the receiving groove 37. Another marking opening 38 communicates with the other end of the receiving slot 37. A slider 61 is slidably connected to the receiving slot 37, and the slider 61 is configured to slide along the extension direction of the receiving slot 37. Two marking layers 63 are located on the side of the slider 61 facing away from the circuit breaker body 1. One end of a connecting post 62 is connected to the slider 61, and the other end of the connecting post 62 is connected to the connecting structure 22. The connecting structure 22 is configured to drive the slider 61 along the receiving slot 37, so that the corresponding marking layer 63 enters the corresponding marking opening 38 when the circuit breaker body 1 is opened or closed. The arrangement of the slider 61 and the marking opening 38 ensures that the slider 61 can only display one state at a time, preventing staff from misidentifying the state.

[0051] Specifically, Figure 1 For example, the marking layer 63 on the left is green and marked with "open", indicating the breaker is in the open state; the marking layer 63 on the right is red and marked with "closed", indicating the breaker is in the closed state. This makes it easier for workers to identify without having to climb up the pole.

[0052] A ventilation hole (not shown) is provided on the top side of the box 3. A canopy 39 is provided on the top of the box 3, spaced apart from the ventilation hole. A wire mesh (not shown) is provided between the canopy 39 and the top side of the box 3, surrounding the top side of the box 3. The ventilation hole helps cool the box 3, the canopy 39 prevents rainwater from entering the box 3 through the ventilation hole, and the wire mesh prevents birds from nesting on the top of the box 3.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
