[0049] Live bypass operation refers to bypassing the normal power supply line and connecting it to the transfer line, with the transfer line temporarily replacing the normal power supply line for power, thereby achieving power outage and maintenance of the normal power supply line while providing uninterrupted power to users.

[0050] In the related art, the operator needs to electrically connect the connection end of the bypass distribution cabinet used to connect the low-voltage busbar with the low-voltage busbar connection end of the line to be repaired in a live state, and electrically connect the connection end of the bypass distribution cabinet used to connect the low-voltage side of the transformer with the low-voltage side connection end of the transformer of the line to be repaired, so that the bypass distribution cabinet and the distribution cabinet to be repaired or replaced are operated in parallel, and then the distribution cabinet to be repaired or replaced is shut down, and the normal conduction between the low-voltage side of the transformer and the low-voltage busbar is completely dependent on the bypass distribution cabinet. After the repair or replacement work is completed, the distribution cabinet after repair or replacement is operated in parallel with the bypass distribution cabinet, and then the bypass distribution cabinet is shut down to restore normal power supply. At present, electrically connecting the bypass distribution cabinet to the line to be repaired in a live state requires the use of multiple tools, which is cumbersome to operate, resulting in low work efficiency, and safety cannot be effectively guaranteed.

[0051] To address the problems existing in the above-mentioned related technologies, the embodiments of the present application provide a power connection device that can electrically connect a bypass power distribution cabinet to a line to be repaired while energized, with simple operation and high safety. It should be noted that the power connection device provided in the embodiments of the present application is not limited to electrically connecting a bypass power distribution cabinet to a line to be repaired while energized, but is also applicable to other scenarios requiring electrical connection of two connection ends while energized, which is not limited here.

[0052] Figure 1 A schematic structural diagram of a power connection device in one embodiment of the present application is shown; Figure 2 Shown Figure 1 A schematic structural diagram of the power connection device shown in another state.

[0053] In some embodiments, see Figure 1 and Figure 2 , an embodiment of the present application provides an electric power connection device, including a main body 100, a first conductive member 200, a clamping fitting 300 and a drive assembly 400. The main body 100 includes a clamping portion 110 and a holding portion 120 connected to the clamping portion 110, and the holding portion 120 is constructed to extend longitudinally in a direction away from the clamping portion 110. The first conductive member 200 is provided on the main body 100, and the first conductive member 200 includes a first part 210 and a second part 220 connected to each other, the first part 210 is provided on the clamping portion 110 and is at least partially located outside the clamping portion 110, and the second part 220 is provided inside the holding portion 120. The first part 210 is used to electrically connect to the first connection end 10, and the second part 220 is used to electrically connect to the second connection end (not shown in the figure).

[0054] The clamping member 300 is rotatably connected to the clamping portion 110. During rotation, the clamping member 300 can move closer to or farther from the clamping portion 110, thereby forming an installation space A between the clamping portion 110 and the clamping portion 110 for clamping or releasing the first connecting end 10. The driving assembly 400 is connected to the clamping member 300 and is used to drive the clamping member 300 to rotate and provide a clamping force acting on the first connecting end 10 through the clamping member 300, so that the first connecting end 10 and the first portion 210 contact each other and are relatively fixed.

[0055] Specifically, in the use scenario of bypass live operation, the first connection end 10 is the low-voltage busbar connection end or the transformer low-voltage side connection end corresponding to the line to be repaired, and the second connection end is the connection end for connecting the low-voltage busbar on the bypass distribution cabinet or the connection end for connecting the low-voltage side of the transformer. The main body 100 and the clamping fitting 300 should be made of insulating materials to ensure the safety of the power connection device. The structural form (such as layered, strip-shaped, etc.) and setting method (such as clipping, attachment, penetration, etc.) of the first conductive component 200 can be selected according to actual conditions, and the embodiments of the present application do not limit this.

[0056] When the power connection device is in use, the second portion 220 of the first conductive member 200 maintains electrical connection with the second connection end (the connection end of the bypass distribution cabinet). An operator can hold the grip portion 120, insert the first connection end 10 (the connection end of the circuit to be repaired) into the installation space A between the clamping portion 110 and the clamping fitting 300, and operate the drive assembly 400 to apply a clamping force to the first connection end 10 via the clamping fitting 300, thereby electrically connecting the first connection end 10 to the first portion 210 of the first conductive member 200, thereby achieving electrical connection between the bypass distribution cabinet and the circuit to be repaired. The power connection device is simple to operate and highly safe.

[0057] In some embodiments, the drive assembly 400 includes a transmission member 410 and an actuator 420. The transmission member 410 is connected to the clamping member 300 and the actuator 420 at both ends, respectively. The actuator 420 is configured to perform linear reciprocating motion along a first direction (direction X in the figure), thereby driving the clamping member 300 to rotate relative to the clamping portion 110 via the transmission member 410.

[0058] As an optional embodiment, the two ends of the transmission member 410 are rotatably connected to the clamping member 300 and the actuator 420, respectively. It can be understood that the clamping member 300, the transmission member 410, and the actuator 420 form a crank slider mechanism, thereby achieving the mutual conversion between rotation and movement. Specifically, in the illustrated embodiment, when the actuator 420 moves away from the rotation axis of the clamping member 300 and the clamping portion 110 in the first direction, the clamping member 300 rotates clockwise and opens relative to the clamping portion 110. When the actuator 420 moves closer to the rotation axis of the clamping member 300 and the clamping portion 110 in the first direction, the clamping member 300 rotates counterclockwise and closes relative to the clamping portion 110.

[0059] Figure 3 Shown Figure 1 A schematic structural diagram of the power connection device shown at another angle.

[0060] In some embodiments, see Figure 3 The driving assembly 400 further includes a mounting housing 430. The mounting housing 430 is fixed to the grip portion 120, and the actuating member 420 is slidably engaged with the inner wall of the mounting housing 430 along a first direction.

[0061] Specifically, the mounting housing 430 is provided with a sliding groove 431 extending longitudinally along a first direction, and the actuator 420 slidably engages with the sliding groove 431. Optionally, the first direction is parallel to the longitudinal direction of the grip portion 120. In this manner, the actuator 420 is slidably arranged relative to the grip portion 120 via the mounting housing 430. This allows an operator to hold the grip portion 120, insert the first connecting end 10 into the mounting space A, and then conveniently operate the actuator 420 to rotate the clamping member 300, thereby improving work efficiency.

[0062] In some embodiments, the actuator 420 includes a slider portion 421 and an operating portion 422. The slider portion 421 is located within the mounting housing 430, with its ends along the first direction connected to the transmission member 410 and the operating portion 422, respectively. The operating portion 422 at least partially extends beyond the mounting housing 430. The portion of the operating portion 422 extending beyond the mounting housing 430 is configured to respond to external forces and drive the slider portion 421 to move in the first direction. An operator can apply force using the portion of the operating portion 422 extending beyond the mounting housing 430 to cause the actuator 420 to slide in the first direction, thereby improving work efficiency.

[0063] Further, see Figure 2 and Figure 3 The operating portion 422 is rotatably connected to the sliding portion 421 around an axis parallel to the first direction. The mounting housing 430 is provided with a limiting groove 432. When the operating portion 422 is in a preset position, the portion of the operating portion 422 extending from the mounting housing 430 can be engaged with the limiting groove 432 during the rotation process. Specifically, the limiting groove 432 is formed on the side wall of the mounting housing 430, and the limiting groove 432 is connected to the sliding groove 431. In this way, when the portion of the operating portion 422 extending from the mounting housing 430 is engaged with the limiting groove 432, the actuator 420 is limited relative to the mounting housing 430 in the first direction, thereby keeping the clamping member 300 open at a certain angle relative to the clamping portion 110, making it easier for the operator to move the power connection device to the position where the first connection end 10 is located and to extend the first connection end 10 into the mounting space A.

[0064] In some embodiments, the drive assembly 400 further includes an elastic member 440 disposed within the mounting housing 430. The two ends of the elastic member 440 are respectively connected to the mounting housing 430 and the actuator 420 to provide an elastic force acting on the actuator 420. The direction of the elastic force is parallel to the first direction and is directed from the actuator 420 to the clamping member 300 (the X direction in the figure is consistent). The elastic force causes the actuator 420 to have a tendency to approach the rotating shaft between the clamping member 300 and the clamping portion 110. As can be seen from the transmission relationship, the clamping member 300 has a tendency to rotate counterclockwise and thus close relative to the clamping portion 110. After the operator releases the grip, the drive mechanism 400 can also use the elastic force generated by the elastic member 440 to cause the clamping member 300 to apply a clamping force to the first connecting end 10, thereby causing the first connecting end 10 and the first portion 210 to contact each other and be relatively fixed.

[0065] Optionally, the elastic member 440 is a compression spring. The elastic member 440 may be connected to either the slider portion 421 or the operating portion 422. In the illustrated embodiment, the elastic member 440 is connected to the operating portion 422 and is in a compressed state, thereby applying the aforementioned elastic force to the actuator 420. In other embodiments, the elastic member 440 is connected to the slider portion 421 and is in a stretched state, thereby applying the aforementioned elastic force to the actuator 420.

[0066] In some embodiments, the drive assembly 400 further includes a limiting rod 450 disposed in the mounting housing 430. The limiting rod 450 penetrates the elastic member 440 and the actuating member 420 along the first direction, thereby limiting the elastic member 440 and the actuating member 420 relative to the mounting housing 430.

[0067] In some embodiments, see Figure 3 The clamping portion 110 is provided with a first arc surface 111 that matches the outer edge of the first connection end 10, and the first portion 210 of the first conductive member 200 is disposed on the first arc surface 111. This not only increases the contact area between the first conductive member 200 and the first connection end 10, thereby improving the conductive effect, but also increases the contact pressure between the first conductive member 200 and the first connection end 10, thereby improving the connection reliability, avoiding loose connections during live bypass operations, and ensuring the normal operation of the equipment.

[0068] In some embodiments, the first portion 210 of the first conductive member 200 is strip-shaped, and a first engaging groove is provided on the first arcuate surface 111. A portion of the first portion 210 is embedded in the first engaging groove for securing the first portion, while another portion is exposed outside the first engaging groove for conductive contact. In other embodiments, the first portion 210 of the first conductive member 200 is layered and attached to the first arcuate surface 111.

[0069] In some embodiments, see Figure 1 and Figure 2 , the power connection device also includes a second conductive component 500. The second conductive component 500 is arranged on the clamping fitting 300 and is at least partially located outside the clamping fitting 300. The second conductive component 500 is used to electrically connect with the first connection end 10 and the first part 210. The structural form (such as layered, strip-shaped, etc.) and setting method (such as clipping, attachment, penetration, etc.) of the second conductive component 500 can be selected according to actual conditions, and the embodiments of the present application are not limited to this. In this way, the first conductive component 200 and the second conductive component 500 are both in contact with the first connection end 10, and the first conductive component 200 and the second conductive component 500 are in contact with each other, which can increase the conductive area and thus improve the conductive effect.

[0070] For explanation with reference to the accompanying drawings, see Figure 2 The clamping fitting 300 opens at a certain angle relative to the clamping portion 110, so that the first connection end 10 can be inserted into the installation space A. At this time, the first conductive member 200 and the second conductive member 500 are offset from each other and do not contact each other. Figure 1 The clamping fitting 300 is close to the clamping portion 110 to clamp the first connection end 10 in the installation space A. At this time, the first conductive component 200 and the second conductive component 500 are aligned and contacted, and the second conductive component 500 is electrically connected to the first connection end 10 and the first part 210.

[0071] In some embodiments, see Figure 3 The clamping fitting 300 has a second arcuate surface 301 that matches the outer edge of the first connection end 10, and the second conductive member 500 is disposed on the second arcuate surface 301. This increases the contact area between the second conductive member 500 and the first connection end 10, thereby improving the conductivity. Furthermore, it increases the contact pressure between the second conductive member 500 and the first connection end 10, thereby improving connection reliability, preventing loose connections during live bypass operations, and ensuring normal operation of the equipment.

[0072] In some embodiments, the second conductive member 500 is strip-shaped, with a second engaging groove provided on the second arc surface 301. A portion of the second conductive member 500 is embedded in the second engaging groove for securing the second conductive member, while another portion is exposed outside the second engaging groove for conductive contact. In other embodiments, the second conductive member 500 is layered and attached to the first arc surface 111.

[0073] In some embodiments, see Figure 1 and Figure 2The power connection device also includes a plug connector 600, one end of which is connected to the end of the gripping portion 120 away from the clamping portion 110 and is electrically connected to the second portion 220 of the first conductive member 200. The other end of the plug connector 600 is constructed as a quick-plug straight-through connector, which can be easily plugged into the second connection end for easy assembly and disassembly.

[0074] In summary, the power connection device provided in the embodiment of the present application includes at least a main body 100, a first conductive member 200, a clamping fitting 300 and a drive assembly 400. The first portion 210 of the first conductive member 200 is electrically connected to the first connection end 10, and the second portion 220 is electrically connected to the second connection end. The drive assembly 400 provides a clamping force acting on the first connection end 10 with the aid of the clamping fitting 300, so that the first connection end 10 and the first portion 210 are in contact with each other and relatively fixed, thereby achieving an electrical connection between the bypass distribution cabinet and the circuit to be repaired. In some embodiments, the power connection device may further include a second conductive member 500 and a plug-in connector 600. The second conductive member 500 is used to increase the conductive area and thus improve the conductive effect. The plug-in connector 600 is used to electrically connect the second portion 220 of the first conductive member 200 to the second connection end for easy assembly and disassembly. The above-mentioned power connection device is simple to operate and highly safe.
