Technical Field

[0001] This utility model belongs to the field of power distribution technology, and in particular relates to a switching device and a bypass load switch system for a bypass load switch. Background Technology

[0002] When using a bypass load switch for bypass transfer operations, a complete bypass transfer operation requires operating the bypass load switch more than ten times. Traditional operations require manual operation by workers, which necessitates repeatedly wearing insulated gloves and boots and using operating rods, increasing operation time and affecting work efficiency. Furthermore, the bypass load switch may be installed in different locations, making manual opening and closing operations with the operating rod difficult and laborious, directly affecting the quality of the operation. In addition, the bypass load switch may malfunction after prolonged use, and manual operation may cause arcing or mechanical explosion, directly threatening the safety of workers. Utility Model Content

For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this utility model will not be described separately.

[0028] like Figure 1 and Figure 3 As shown, in a first aspect, this utility model provides a switching device for a bypass load switch, including a housing 100, a motor assembly 300, and a robotic arm assembly 200. The motor assembly 300 is fixedly connected to the housing 100 and has a rotating shaft. One end of the robotic arm assembly 200 is connected to the rotating shaft of the motor assembly 300, and the other end of the robotic arm assembly 200 has a connection structure for connecting to a bypass load switch 500. The motor assembly 300 drives the robotic arm assembly 200 to open or close the bypass load switch 500. A wireless component (not shown in the figures) is provided inside the housing 100 for communication with the motor assembly 300. The switching device also includes a control terminal 400, which is wirelessly connected to the wireless component.

[0029] The switch 501 of the bypass load switch 500 is used to control the opening or closing of the bypass load switch 500, and the switch locking switch 502 is used to unlock or lock the movement of the switch 501 on the bypass load switch 500.

[0030] In practical applications, the housing 100 is mounted on the bypass load switch 500. Please refer to [link / reference]. Figure 2 The housing 100 can be installed above the bypass load switch 500, and the housing 100 is fixedly connected to the motor assembly 300. The upper end of the robotic arm assembly 200 is connected to the rotating shaft of the motor assembly 300. The motor assembly 300 and the robotic arm assembly 200 are located on one side of the housing 100 corresponding to the front side of the bypass load switch 500. The switch gate 501 and the switch locking gate 502 of the bypass load switch 500 are both located below the front side of the bypass load switch 500. The lower end of the robotic arm assembly 200 is connected to the switch gate 501 or the switch locking gate 502 through a connecting structure, so that the robotic arm assembly 200 can control the switch gate 501 and the switch locking gate 502.

[0031] Specifically, the robotic arm assembly 200 includes a first transmission assembly 210, and the motor assembly 300 includes a first motor 301, which has a rotating shaft. The first transmission assembly 210 includes a first transmission rod 211 and a first transmission arm 212. A first end of the first transmission rod 211 is fixedly connected to the rotating shaft of the first motor 301, and a second end of the first transmission rod 211 is rotatably connected to the first end of the first transmission arm 212. The second end of the first transmission arm 212 is rotatably connected to the switch 501 of the bypass load switch 500. The rotating shaft of the first motor 301 rotates forward or backward, causing the second end of the first transmission rod 211 to rise or fall.

[0032] When the first motor 301 rotates through the shaft and causes the second end of the first transmission rod 211 to rise, since the first end of the first transmission arm 212 is rotatably connected to the second end of the first transmission rod 211, the first transmission arm 212 is driven upward by the first transmission rod 211; the second end of the first transmission arm 212 is rotatably connected to the switch 501, so the first transmission arm 212 can push and pull the switch 501 upward.

[0033] It is understandable that the second end of the first transmission rod 211 can also be lowered in the same way, the first transmission rod 211 drives the first transmission arm 212 downward, and then the first transmission arm 212 drives the switch 501 to descend.

[0034] Specifically, the connection structure includes a first connecting pin 213, which is used to insert into the first transmission arm 212 and the switch 501, and to rotatably connect the first transmission arm 212 and the switch 501.

[0035] To enable the switch 501 to follow the rise or fall of the first transmission arm 212, a first connecting pin 213 is inserted into the first transmission arm 212, and the first connecting pin 213 is simultaneously inserted into the switch 501. The first transmission arm 212 is rotatably connected to the switch 501 with the first connecting pin 213 as its pivot. When the first transmission arm 212 rises or falls, it drives the switch 501 to swing up and down via the first connecting pin 213.

[0036] Specifically, the first transmission arm 212 has an opening (not shown in the figure), and the switch 501 has an opening near its end (not shown in the figure). When the first transmission arm 212 and the switch 501 need to be connected, the first connecting pin 213 passes through the opening on the switch 501 and the opening on the first transmission arm 212. The first connecting pin 213 serves as the pivot for the pivot connection between the first transmission arm 212 and the switch 501, thereby enabling the first transmission arm 212 to drive the switch 501.

[0037] When installing the housing 100 onto the bypass load switch 500, the operator can first coordinate the positions of the first transmission arm 212 and the switch 501, and insert the first connecting pin 213 into the respective openings of the first transmission arm 212 and the switch 501, so that the first transmission arm 212 and the switch 501 are rotatably connected. When the operator needs to remove the housing 100 from the bypass load switch 500, the first connecting pin 213 can be pulled out to disconnect the first transmission arm 212 from the switch 501.

[0038] Specifically, the robotic arm assembly 200 includes a second transmission assembly 220, and the motor assembly 300 includes a second motor 302 with a rotating shaft. The second transmission assembly 220 includes a second transmission rod 221 and a second transmission arm 222. The first end of the second transmission rod 221 is fixedly connected to the rotating shaft of the second motor 302, and the second end of the second transmission rod 221 is rotatably connected to the first end of the second transmission arm 222. The second end of the second transmission arm 222 is rotatably connected to the switch locking gate 502 of the bypass load switch 500. The rotating shaft of the second motor 302 rotates forward or backward, causing the second end of the second transmission rod 221 to rise or fall.

[0039] When the second motor 302 rotates through the shaft and causes the second end of the second transmission rod 221 to rise, since the first end of the second transmission arm 222 is rotatably connected to the second end of the second transmission rod 221, the second transmission arm 222 is driven upward by the second transmission rod 221. The second end of the second transmission arm 222 is rotatably connected to the switch locking gate 502, so the second transmission arm 222 can push and pull the switch locking gate 502 upward.

[0040] It is understandable that the second end of the second transmission rod 221 can also be lowered in the same way, the second transmission rod 221 drives the second transmission arm 222 downward, and then the second transmission arm 222 drives the switch locking gate 502 to descend.

[0041] Specifically, the connection structure includes a second connecting pin 223, which is used to insert into the second transmission arm 222 and the switch locking gate 502, and to rotatably connect the second transmission arm 222 and the switch locking gate 502.

[0042] To enable the switch locking gate 502 to follow the rise or fall of the second transmission arm 222, a second connecting pin 223 is inserted into the second transmission arm 222, and the second connecting pin 223 is simultaneously inserted into the switch locking gate 502. The second transmission arm 222 is rotatably connected to the switch locking gate 502 with the second connecting pin 223 as its pivot. When the second transmission arm 222 rises or falls, it drives the switch locking gate 502 to swing up and down via the second connecting pin 223.

[0043] Specifically, the second transmission arm 222 has an opening (not shown in the figure), and the switch locking gate 502 has an opening near its end (not shown in the figure). When the second transmission arm 222 and the switch locking gate 502 need to be connected, the second connecting pin 223 passes through the opening on the switch locking gate 502 and the opening on the second transmission arm 222. The second connecting pin 223 serves as the pivot for the pivot connection between the second transmission arm 222 and the switch locking gate 502, thereby enabling the second transmission arm 222 to drive the switch locking gate 502.

[0044] When installing housing 100 onto bypass load switch 500, the operator can first coordinate the positions of the second transmission arm 222 and the switch locking gate 502, and insert the second connecting pin 223 into the respective openings of the second transmission arm 222 and the switch locking gate 502, so that the second transmission arm 222 and the switch locking gate 502 are rotatably connected. When the operator needs to remove housing 100 from bypass load switch 500, the second connecting pin 223 can be pulled out to disconnect the second transmission arm 222 from the switch locking gate 502.

[0045] Understandably, when the switching device is installed on the bypass load switch 500, the user may need to temporarily operate the switch 501 and the switch locking switch 502 manually. To address this, pull rings can be provided on the first connecting pin 213 and the second connecting pin 223, so that when the user needs to manually operate the switch 501 and the switch locking switch 502, the user can remove the first connecting pin 213 and the second connecting pin 223 by inserting the insulating operating rod into the pull ring. This allows the switch 501 and the switch locking switch 502 to be manually operated even when the switching device is installed on the bypass load switch 500.

[0046] A wireless component is installed within the housing 100. This wireless component is communicatively connected to the motor assembly 300 and remotely connected to the control terminal 400. Thus, the operator can remotely control the motor assembly 300 via the control terminal 400, thereby driving the robotic arm assembly 200 to actuate the switch gate 501 and the switch locking gate 502. In specific applications, a control circuit board can be installed within the housing 100, and the wireless component (which can be a WIFI module, Bluetooth module, etc.) can be installed on the control circuit board. The motor assembly 300 can be connected to the control circuit board via a wiring harness.

[0047] By implementing the above scheme, when the circuit breaker is installed on the bypass load switch 500, the operator can remotely control the circuit breaker via the control terminal 400, and remotely control the mechanical arm assembly 200 on the housing 100 via the remote control motor assembly 300, thereby controlling the switch gate 501 and the switch locking gate 502 to open or close the bypass load switch 500. This eliminates the need for manual operation, saves effort, simplifies operation, ensures operator safety, and improves work efficiency.

[0048] When operating outdoors, the housing 100 can protect the wireless components from external damage; the opening and closing operation of the bypass load switch 500 by the opening and closing device is completed by the mechanical arm component 200 driven by the motor component 300, which solves the problem of difficult and laborious operation when operating the bypass load switch 500 manually in the traditional way; the wireless component and control terminal 400 enable the opening and closing device to be remotely controlled, which can solve the problem of difficult operation of the bypass load switch 500 by the staff to a certain extent.

[0049] Understandably, the housing 100 may be provided with a battery or power interface to power the motor assembly 300 and the wireless component, and the housing 100 may be provided with a power switch for controlling the power supply of the motor assembly 300 and the wireless component.

[0050] In some embodiments, the housing 100 is disposed on the upper end of the bypass load switch 500 and surrounds the upper end of the bypass load switch 500. The housing 100 has a fixing notch 101 on one side corresponding to the handling handle 503 on the bypass load switch 500. The fixing notch 101 is used to engage the handling handle 503.

[0051] In practical applications, please refer to Figure 2 A handling handle 503 is provided on the upper side of the bypass load switch 500. In order to make the housing 100 more stable on the bypass load switch 500, a fixing notch 101 can be opened on the side of the housing 100 corresponding to the handling handle 503. When the housing 100 is installed on the upper end of the bypass load switch 500, the handling handle 503 is locked into the fixing notch 101, thereby fixing the housing 100 on the bypass load switch 500. The structure is simple.

[0052] In some embodiments, a fixing screw 102 is provided on one side of the housing 100 corresponding to the front side of the bypass load switch 500, and the fixing screw 102 is used to press the bypass load switch 500 into the housing 100.

[0053] Please see Figure 2 The fixing screw 102 is inserted into the housing 100 and presses the bypass load switch 500 inside the housing 100 to ensure that the relative position between the opening and closing device and the bypass load switch 500 is stable.

[0054] In some embodiments, the housing 100 is provided with a circuit breaker indicator light group 110.

[0055] In practical applications, the housing 100 is equipped with a circuit breaker indicator light group 110 to indicate the status of the circuit breaker / the status of the bypass load switch 500 is known based on the status of the circuit breaker / the operator can confirm the execution result of the circuit breaker after the control terminal 400 issues a command to the wireless component.

[0056] For example, please refer to Figure 2 and Figure 2aIn this embodiment, the opening and closing indicator light group 110 may include four individual indicator lights. In one possible implementation scenario, among the four indicator lights of the opening and closing indicator light group 110, the first indicator light 111 indicates whether the current motor assembly 300 is energized, the second indicator light 112 indicates whether the current first motor 301 has rotated to the closed / open state of the switch gate 501, the third indicator light 113 indicates whether the current second motor 302 has rotated to the unlocked / locked state of the switch locking gate 502, and the fourth indicator light 114 indicates whether the current wireless component inside the housing 100 is connected to the control terminal 400. Thus, operators can intuitively understand the operating status of the opening and closing device or the bypass load switch 500 by observing the illumination or extinguishing of the opening and closing indicator light group 110.

[0057] Understandably, each indicator light in the circuit breaker indicator light group 110 can have a different color for easy identification.

[0058] In some embodiments, the housing 100 is provided with a knob assembly 120 for controlling the rotation of the first motor 301 and the second motor 302.

[0059] In some implementation scenarios, when the switching device is located on the bypass load switch 500, operators may need to operate the switching gate 501 or the locking gate 502 of the bypass load switch 500 without using the control terminal 400. For this purpose, a knob assembly 120 can be provided on the housing 100 to control the rotation of the first motor 301 and the second motor 302. Operators can use the knob assembly 120 to control the rotation of the first motor 301 or the second motor 302, which in turn drives the first transmission component or the second drive component 220 to perform up-and-down pushing and pulling actions, thereby controlling the switching gate 501 to open or close, and the locking gate 502 to unlock or lock.

[0060] Specifically, please refer to Figure 2 and Figure 2a In this embodiment, the knob assembly 120 includes a first knob 121 and a second knob 122 disposed on the housing 100. The first knob 121 and the second knob 122 respectively control the rotation of the first motor 301 and the second motor 302.

[0061] The operator can control the first motor 301 to rotate by turning the first knob 121 provided on the housing 100, thereby causing the first transmission component 210 to push and pull the switch 501 up and down.

[0062] The operator can control the rotation of the second motor 302 by turning the second knob 122 provided on the housing 100, thereby causing the second transmission component 220 to push and pull the lock gate 502.

[0063] By implementing the above scheme, staff can operate the motor assembly 300 by manipulating the knob assembly 120 on the housing 100, thereby driving the robotic arm assembly 200 to push and pull the switch gate 501 or the switch locking gate 502 up and down. This is suitable for emergency situations where the control terminal 400 is not nearby or the wireless signal is interfered with.

[0064] In some embodiments, the control terminal 400 is provided with a trip button and a trip button, which are used to control the first motor 301 to rotate clockwise and counterclockwise, respectively; the control terminal 400 is also provided with an unlock button and a lock button, which are used to control the second motor 302 to rotate clockwise and counterclockwise, respectively.

[0065] Specifically, please refer to Figure 3 In this embodiment, the control terminal 400 is equipped with four buttons: a trip button 410, a close button 420, an unlock button 430, and a lock button 440. By pressing the corresponding button, the operator can control the first motor 301 to rotate clockwise or counterclockwise to drive the first transmission component 210 to perform tripping or closing operations on the switch 501, and control the second motor 302 to rotate clockwise or counterclockwise to drive the second transmission component 220 to perform unlocking or locking operations on the switch locking gate 502.

[0066] Secondly, this application also provides a bypass load switch system, including the opening and closing device described in the first aspect and a bypass load switch 500. The bypass load switch 500 is provided with a switch locking gate 502 and a switch gate 501. The opening and closing device is used to be installed on the bypass load switch 500. The robotic arm assembly 200 is connected to the switch gate 501 and the switch locking gate 502.

[0067] Specifically, the process of using the opening and closing device is as follows:

[0068] Step 1: Inspect and install the switching device

[0069] First, check if the control terminal 400 is working properly. Then, check if the appearance of the robotic arm assembly 200 and the opening / closing indicator light group 110 is intact and undamaged. Next, align the fixing notch 101 on the housing 100 with the handling handle 503 of the bypass load switch 500 and put the housing 100 on the bypass load switch 500. Insert the fixing screw 102 into the housing 100 and abut against the bypass load switch 500 inside the housing 100.

[0070] Step 2: Dating the first transmission assembly 210 and the second transmission assembly 220

[0071] Ensure that the first transmission assembly 210 and the second transmission assembly 220 are normally connected to the first motor 301 and the second motor 302, respectively, or install the first transmission assembly 210 and the second transmission assembly 220 on the first motor 301 and the second motor 302, respectively; align the openings on the first transmission arm 212 and the second transmission arm 222 with the openings on the switch gate 501 and the switch locking gate 502, respectively; insert the first connecting pin 213 into the openings on the first transmission arm 212 and the switch gate 501, and insert the second connecting pin 223 into the openings on the second transmission arm 222 and the switch locking gate 502, ensuring that the first transmission arm 212 is connected to the switch gate 501 by means of the first connecting pin 213, and ensuring that the second transmission arm 222 is connected to the switch locking gate 502 by means of the second connecting pin 223.

[0072] Step 3: Status Confirmation

[0073] Connect the power supply, turn on the power switch on the housing 100, and check whether the indicator light (first indicator light 111) in the control indicator light group 110 that indicates whether the current motor assembly 300 is powered on is lit normally.

[0074] Step 4: Remote Control Operation

[0075] When an operator presses the unlock button 430 on the control terminal 400, the control terminal 400 sends a signal to the wireless module. The wireless module controls the second motor 302 to rotate, thereby driving the second transmission component 220 to push and pull the switch locking gate 502 to the unlocked state. During this process, the indicator light (third indicator light 113) in the open / close indicator light group 110 that indicates whether the switch locking gate 502 is in the unlocked or locked state lights up or goes out. After the switch locking gate 502 is in the unlocked state, the operator presses the open button 410 or the close button 420 on the control terminal 400. The control terminal 400 sends a signal to the wireless module, which controls the first motor 301 to rotate, thereby driving the first transmission component 210 to push and pull the switch gate 501, causing the switch gate 501 to open or close. During this process, the indicator light (second indicator light 112) in the open / close indicator light group 110 that indicates whether the switch gate 501 is in the closed or open state lights up or goes out. After the operation is completed, the staff presses the lock button 440 on the control terminal 400. The control terminal 400 sends a signal to the wireless module, which controls the second motor 302 to rotate, thereby driving the second transmission component 220 to push and pull the lock gate 502 to the locked state.
