[0023] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0024] like Figure 1-3As shown, a pole-mounted circuit breaker with integrated current and voltage sensors includes a pole-mounted circuit breaker body 1 and a circuit measuring device 3. The circuit measuring device 3 includes a sensor 8 and a storage device 9. The sensor 8 is disposed on the pole-mounted circuit breaker body 1 and measures the circuit information of the pole-mounted circuit breaker body 1. The sensor 8 includes at least one of a voltage transformer and a current transformer. The pole-mounted circuit breaker body 1 is provided with a device mounting port 2. The storage device 9 is inserted into the device mounting port 2 by means of insertion, screwing, or other methods. The storage device 9 is communicatively connected to the sensor 8 in the inserted position to record measurement data. It also includes an auxiliary operating device 4. The auxiliary operating device 4 includes a fixing frame 5, an unlocking component 6, and a limiting component 7. The fixing frame 5 is connected to the pole, and the unlocking component 6 is insulated and disposed on the fixing frame 5. The limiting component 7 is movably disposed inside the device mounting port 2. When the storage device 9 is inserted into the device mounting port 2, it engages with the limiting component 7. The unlocking component 6 is linked to the limiting component 7 to control the locking or disengagement of the limiting component 7 from the circuit measuring device 3.

[0025] Sensor 8 can monitor the transmission line corresponding to the pole-mounted circuit breaker body, and its related measurement data is saved to the storage device 9 connected to it. Voltage transformers and current transformers can be directly purchased, specifically using the Modbus RTU standard protocol and connected to the storage device 9 via interfaces such as RS485. The storage device 9 can adopt a loop-overwrite storage method similar to a dashcam, so that when data is retrieved, it always records the parameter data of the most recent period, thus eliminating the need for excessive hard drive space for the storage device 9 and effectively reducing equipment procurement costs; Reference Figure 2 and Figure 3 The mounting bracket 5 includes two crossbeams supporting the weight of the pole-mounted circuit breaker body 1 and a sleeve that fastens and holds the pole 10. The pole-mounted circuit breaker body 1 can be specifically fixed to the beams by positioning bolts to ensure its own positional stability. Screws can also be inserted between the sleeve and the pole 10 to further improve the installation strength. By using the unlocking component 6 to control the limit component 7, it is easy for operators at height to access and replace the storage device 9. In the event of a fault at a node or on a certain line, the recent circuit monitoring data can be quickly read, which is convenient for maintenance personnel to determine the cause of the fault and troubleshoot its location and scale. At the same time, the insulation effect at the connection between the unlocking component 6 and the pole-mounted circuit breaker body 1 can form a double insurance with the insulation of the pole-mounted circuit breaker body 1 itself, ensuring the personal safety of operators at height when grabbing or leaning against it.

[0026] The unlocking component 6 is elastically hinged to the fixing frame 5, and the unlocking component 6 can swing around the hinge point; when the unlocking component 6 is in its natural state, the limiting member 7 is in the locking position; when the unlocking component 6 is swung by an external force, the limiting member 7 moves to the disengaged position accordingly; when the external force is removed, the unlocking component 6 swings back to its initial position under the action of elastic restoring force, and drives the limiting member 7 back to the locking position.

[0027] The advantage of the flexible connection is that it can trigger the unlocking action when force is applied and automatically restore the lock when the force is released, thereby simplifying the entire operation process and reducing operation time. At the same time, the hinged form allows the unlocking part 6 to have a circular range of motion covering the vicinity of the operator, which can effectively make good use of the three-dimensional space that the limbs can reach. Moreover, the degree of tilt of the unlocking part 6 when swinging is easier to quickly determine the stroke position by observation compared to the telescopic part, thus improving operational safety.

[0028] The unlocking component 6 is located at the lowest point of its rotation range in the initial position, and the end of the unlocking component 6 away from the hinge point rotates upward during the unlocking swing.

[0029] Setting the initial position of the unlocking component 6 to the lowest point can effectively prevent birds from temporarily standing on it or other objects from bumping into it and causing the unlocking component 6 to be pressed down and misoperated. This ensures that the unlocking effect will only occur when the workers at height deliberately push it upwards, significantly improving the safety of the facility.

[0030] like Figure 4 As shown, the unlocking component 6 includes a connecting rod 61 and an extension rod 62; one end of the connecting rod 61 is hinged to the fixing frame 5, and the other end is connected to the extension rod 62; the extension rod 62 is damped and sleeved on the connecting rod 61, and its extension length can be adjusted along the length direction of the connecting rod 61.

[0031] The extension rod 62 can extend the lever arm before the unlocking operation to save effort, and it can also provide more gripping and support areas to adapt to the position of the climber and reduce the difficulty of position adjustment.

[0032] An abutment 63 is fixedly installed on the outside of the extension rod 62; an abutment groove 64 is provided on the downward-facing area of ​​the abutment 63, and the interior of the abutment groove 64 is provided with anti-slip texture.

[0033] For operators working at height, there are several methods of operation. One is to grip the connecting rod 61 or extension rod 62 with your hand, then apply force with your entire arm to pull the unlocking component 6, causing the limiting component 7 to unlock. Another method is to use your elbow, forearm side, or other parts to rest against the surface of the abutment groove 64 or the connecting rod 61 / extension rod 62, then apply force with your entire arm to pull the unlocking component 6, causing the limiting component 7 to unlock. This method is suitable when the operator is preparing to retrieve the storage device 9 with one hand, but the other hand is unavailable. A third method is to use the side of the thigh or knee of one leg to rest against the surface of the abutment groove 64 or the connecting rod 61 / extension rod 62, then apply force with the entire leg to pull the unlocking component 6, causing the limiting component 7 to unlock. This completely frees up both hands, allowing for more flexible operation.

[0034] The unlocking component 6 is located below the mounting port 2; the inner contour of the abutment groove 64 matches the human knee.

[0035] When the unlocking component 6 is positioned below the mounting port 2, the upper body of the operator is approximately at the same height as the mounting port 2, allowing their legs to be raised and rest against the abutment groove 64 for unlocking operations. This design is more ergonomic and reduces the difficulty of operation. The reason for preferring to use the knee rather than the side where the quadriceps muscle is located is that the knee position (including when wearing knee braces) can provide a stable protrusion that can be partially embedded into the abutment groove 64, making the force applied when driving the unlocking component 6 to rotate more smoothly.

[0036] like Figure 5-6 As shown, the limiting member 7 includes an elastically telescopic insert 71; the insert 71 is connected to the unlocking member 6 via a traction rope 72, and is tightened or loosened as the unlocking member 6 rotates; the storage device 9 has a slot 91 on its side, and when the storage device 9 is inserted into the device mounting port 2, the insert 71 is inserted into the slot 91; the slots 91 are spaced apart along the length of the storage device 9, and the slots 91 correspond to different embedding depths of the storage device 9 in the device mounting port 2.

[0037] When the unlocking component 6 rotates, the traction rope 72 wound on the inward side of the shaft will tighten, and as the rotation angle increases, it will pull the other end of the traction rope 72, the insert 71, so that it will disengage from the slot 91, allowing the storage device 9 to leave the device mounting hole 2 freely. By setting multiple slots 91, the storage device 9 can be aligned with the insert 71 multiple times during the process of leaving the device mounting hole 2, so that it can be temporarily fixed in the middle of the process of taking out the storage device 9, effectively dealing with special situations such as strong winds encountered in the operation diagram, and improving the safety of taking out the storage device 9.

[0038] The equipment installation port 2 is internally connected to an arrangement channel 21; the arrangement channel 21 has a two-section bent structure, and the bent part is higher than the opening of the equipment installation port 2; the insert 71 is telescopically embedded in the inner wall of the arrangement channel 21 near the section of the equipment installation port 2.

[0039] The arrangement channel 21 has a two-section structure, which allows the section near the equipment installation port 2 to be inserted in reverse, thereby preventing rainwater from seeping into the interior of the pole-mounted circuit breaker body 1 under the action of gravity, thus improving the insulation and waterproof performance. Anti-slip pads can be installed on the side walls of the arrangement channel 21, so that the storage device 9 can remain stationary by the friction of the anti-slip pads when it is not completely removed, and will not fall out along the inclined slope. At the same time, a shelf can be added directly below the equipment installation port 2 to further prevent the storage device 9 from falling due to slipping or accidental bumps.

[0040] The sensor 8 is externally connected to a wiring connector 81; the wiring connector 81 includes a base 82, which is connected to the two bends of the arrangement channel 21; the base 82 is provided with interconnected terminals 83 and a first connecting part 84; the terminals 83 are connected to the sensor 8 via a wire harness; the embedded end of the storage device 9 is provided with a second connecting part 92; when the storage device 9 is fully inserted into the device mounting port 2, the first connecting part 84 and the second connecting part 92 are fitted together, and the storage device 9 continuously records the detection data on the sensor 8.

[0041] As mentioned above, the first connecting part 84 and the second connecting part 92 can be connected and cooperated using various types of interfaces such as RS485 and USB; the signal output end of the sensor 8 can be led into the arrangement channel 21 through the line connector 81, which is convenient for connection with the storage device 9.

[0042] A sealing sleeve 93 is also provided on the outer surface of the storage device 9; the sealing sleeve 93 is fitted into the device mounting port 2; when the storage device 9 is fully inserted into the device mounting port 2, the outer contour of the sealing sleeve 93 matches the inner wall of the device mounting port 2, blocking the arrangement channel 21.

[0043] The sealing sleeve 93 can increase friction and improve the stability of the insertion installation. On the other hand, it can further improve the dustproof and moisture-proof capabilities of the arrangement channel 21, ensuring the stable operation of the equipment for a long time and reducing the failure rate.
