Description

Technical Field

[0001] This invention relates to the field of power equipment testing and maintenance tools, and in particular to an adaptive portable high-voltage testing wiring device. Background Technology

[0002] In the operation and maintenance of power systems, preventative tests such as loop resistance testing and dielectric loss testing of high-voltage electrical equipment like transformers, circuit breakers, and disconnectors are routine and important tasks. These tests typically require establishing temporary, reliable test circuits at high altitudes or long distances using wiring devices in environments where the equipment is energized or near energized conductors.

[0003] Currently, the wiring devices used on-site are mainly divided into the following categories, but all of them have obvious technical limitations: (1) Traditional manual wiring pliers: These tools are mostly simple mechanical clamping structures, which are operated remotely by an insulated operating rod. The prominent problems are: (a) the clamping force depends entirely on human feel and physical strength. It is difficult to ensure stable and sufficient contact pressure under the condition of long insulated rods at high altitudes, which can easily lead to excessive contact resistance and affect the test accuracy; (b) they cannot deal with oxide layers, paint or dirt on the conductor surface. These insulating layers can directly lead to test failure or serious data deviation; (c) the operation process depends entirely on the operator's experience and safety awareness. There is a lack of objective and real-time detection means to detect whether the conductor is live or whether the contact is good, which poses a safety risk of accidentally touching a live body.

[0004] (2) Improved devices with single functions: To partially solve the above problems, integrated functional solutions have emerged, but each has its shortcomings. For example, a high-altitude wiring clamp with a grinding function (such as CN205176069U) adds a grinding machine, but the clamping is still manual and does not integrate electrical safety status detection function, so the grinding operation itself has a safety blind spot. Another high-altitude wiring automatic clamping device (such as CN207150026U) uses an electric mechanism to achieve automatic clamping, but its design only focuses on the clamping action and does not involve conductor surface treatment and safety status verification before operation.

[0005] While existing automatic clamping devices improve operational convenience, their fundamental flaws lie in their isolated functions and lack of intelligent safety status logic. They fail to consider the three essential aspects of high-voltage testing—safety status verification, surface treatment, and reliable connection—as a unified, interconnected system. Their simple control mechanisms cannot make safety status decisions based on the conductor's real-time electrical condition or intervene in subsequent operations, leaving inherent risks and efficiency bottlenecks.

[0006] In summary, existing technologies fail to achieve integrated and intelligent linkage of safety status detection, surface treatment, and reliable connection. The workflow has loopholes, relying on manual connection and subjective judgment. Therefore, there is an urgent need for a wiring device that can deeply integrate the above functions and achieve forced safety status interlocking and process closure through built-in intelligent control, in order to fundamentally improve the safety, reliability, and efficiency of operations. Summary of the Invention

[0007] To overcome the shortcomings of existing high-voltage test wiring devices, such as fragmented functions, reliance on manual series operation, and lack of active safety protection, the main technical objective of this invention is to provide an adaptive portable high-voltage test wiring device that integrates functions such as electrical safety status verification, conductor surface treatment, and reliable mechanical connection, and achieves forced safety status interlocking and closed-loop operation process through intelligent control logic.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: An adaptive portable high-voltage test wiring device includes an insulated telescopic pole, and further includes: A clamping module, installed on the insulating telescopic rod, is used to clamp the conductor being tested; A grinding module, installed on the insulating telescopic rod, is used to grind the surface of the conductor being tested; An acoustic-optical voltage detection module, the detection end of which is electrically connected to the clamping module, is used to detect the electrical state between the clamping module and the conductor under test; The control module is electrically connected to the acoustic-optical voltage detection module, the driving component of the clamping module, and the grinding module, respectively. The control module is configured to: receive the detection signal from the acoustic and optical voltage detection module and perform the first electrical status detection; when the detection signal indicates that there is electricity or continuity, prohibit the grinding module from starting and / or prohibit the clamping module from performing the clamping action; and perform a second electrical execution detection after grinding is allowed and before final clamping.

[0009] Preferably, the control module is specifically configured to execute a safety state operation process that includes the following logic: When the clamping module contacts the conductor under test, the first electrical condition detection is initiated. If the initial detection determines that the state is dangerous, the first control strategy is executed; the first control strategy includes triggering an alarm and locking the grinding module and clamping function. If the initial detection determines that the state is safe, then the second control strategy is executed; the second control strategy includes starting the grinding module to perform grinding, and after the grinding is completed, starting a secondary electrical status detection, and controlling the clamping module to finally clamp based on the result of the secondary electrical status detection.

[0010] Preferably, the initial electrical condition detection includes voltage detection and micro-current conduction detection; the control module is configured to combine the signals from both to determine a dangerous or safe state. The locking in the first control strategy is an electrical lock, and the control module maintains the lock until it receives a clear manual reset command.

[0011] The permission to start the grinding module is achieved by releasing its electrical lock at the moment of startup; the control of the clamping module to finally clamp based on the result of the secondary electrical status detection is specifically as follows: if the result of the secondary electrical status detection meets the preset good conduction conditions, the clamping module is controlled to perform clamping and enter the self-locking state; otherwise, a protection action is triggered.

[0012] Preferably, the control module is further configured to: monitor the contact signal in real time during the process of the clamping module contacting the conductor under test, and use this as a trigger condition to start the acoustic-optical voltage detection module.

[0013] Preferably, the control module is configured to: in the safe state, release the electrical lock on the grinding module only before it is started; and in the dangerous state, maintain the electrical lock on the grinding module and the clamping module drive component until a manual reset command is received.

[0014] Preferably, the clamping module includes: The fastener is equipped with upper clamping teeth; The movable component is slidably connected to the fixed component and is provided with lower clamping teeth; An electric actuator, the output end of which is connected to the movable component; An elastic pad is provided between the upper jaw teeth and the lower jaw teeth.

[0015] Preferably, it also includes a pressure sensor, which is disposed on the drive chain of the electric push rod or on the lower jaw and is electrically connected to the control module; the control module is further configured to adjust the clamping force according to the feedback signal of the pressure sensor when the final clamping is performed in step C.

[0016] Preferably, the device further includes a wireless communication module connected to the control module; the control module is further configured to receive remote operation commands through the wireless communication module and send device status, detection results and alarm information to a remote terminal.

[0017] Preferably, the grinding module is mounted via an angle-adjustable fixed bracket, which is equipped with a locking mechanism for adjusting the angle of the grinding head.

[0018] Preferably, it also includes an ambient light sensor, an auxiliary lighting unit, an angle adjustment mechanism, and a vibration monitoring module; An ambient light sensor and an auxiliary lighting unit are provided. The ambient light sensor senses the intensity of ambient light during operation, and the control module controls the auxiliary lighting unit to automatically turn on when there is insufficient light, providing supplementary lighting for the working area of ​​the grinding module. An angle adjustment mechanism is provided on the insulating telescopic rod, including a plum blossom joint and a butterfly locking screw, for manually adjusting the pitch angle of the clamping module; A vibration monitoring module is mounted on the fixed bracket of the grinding module or the clamping module, and is used to detect abnormal vibrations during operation; The control module is configured to: transmit device status information, including data from the vibration monitoring module, via the wireless communication module; when the vibration monitoring module detects abnormal vibration exceeding a threshold, the control module can reduce the rotation speed of the grinding module or trigger an alarm.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In this invention, by embedding the acoustic and optical voltage detection module at the front end of the wiring and electrically connecting it to the clamping module, the control module can obtain the conductor's energized state and initial conductivity in real time the moment the clamping jaws contact the conductor. Based on this signal, the control module executes the core safety state logic: once energization or abnormal conductivity is detected, the grinding module is immediately prohibited from starting and the clamping module from performing the final clamping action. Through an interlocking mechanism that includes detection, judgment, and prohibition, the possibility of grinding and tightening operations under dangerous conditions is physically eliminated, transforming the traditional passive safety state that relies on human visual observation and experience into an active safety state that is enforced by the equipment hardware and program. Even in the event of operator negligence, the device itself can act as a reliable second guardian, effectively preventing serious accidents such as electric shock and short circuits, thereby improving the inherent safety state.

[0020] (2) In this invention, after verifying the electrical safety status, the control module allows the grinding module to be activated to process the conductor surface. After grinding, the device does not clamp directly, but the control module instructs a secondary electrical status verification to confirm whether the ground contact surface has met the good conductivity requirements. This pre-processing-re-verification closed-loop process systematically solves the problem of excessive contact resistance caused by oxide layers, paint, etc. Only after secondary verification and confirmation that the contact surface meets the standards does the device perform the final clamping, thereby ensuring that the contact resistance of each test wiring is in a low and stable state. This fundamentally eliminates test data deviations or instrument false alarms caused by poor contact, and significantly improves the accuracy and reliability of test data.

[0021] (3) In this invention, multiple previously discrete processes such as voltage testing, grinding, verification, and clamping are integrated into a single device's one-time operation process. All process switching and safety status decisions are automatically completed by the control module according to preset logic, with the operator mainly responsible for positioning and triggering. This completely changes the complex mode of traditional operations that requires carrying multiple tools and repeatedly climbing to adjust, simplifying and standardizing the operation process, reducing reliance on personnel skills and experience, and reducing physical exertion and high-altitude operation time. In addition, its integrated and portable design is particularly suitable for complex environments such as substations and field lines, resulting in a substantial improvement in overall operation efficiency.

[0022] (4) In this invention, the sound and light alarm provides real-time on-site feedback, while the control module processes the detection signal, judgment result and execution action throughout the process, which essentially generates a complete set of electronic operation logs, laying the foundation for subsequent expansion of data storage and transmission functions (such as wireless modules), so that the safety status and processing results of each wiring operation can be recorded and traced, thereby providing reliable data support for the standardized and intelligent management of power safety status production, and bringing important management benefits.

[0024] To better illustrate the objectives, technical solutions, and advantages of the present invention, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] While existing automatic clamping devices improve operational convenience, their fundamental flaws lie in their isolated functions and lack of intelligent safety status logic. They fail to consider the three essential aspects of high-voltage testing—safety status verification, surface treatment, and reliable connection—as a unified, interconnected system. Their simple control mechanisms cannot make safety status decisions based on the conductor's real-time electrical condition or intervene in subsequent operations, leaving inherent risks and efficiency bottlenecks.

[0026] Therefore, according to embodiments of the present invention, an intelligent device integrating safety status detection, surface treatment, and reliable connection is provided. Through built-in control logic, the device realizes mandatory safety status interlocking and automated closed-loop of the work process, fundamentally improving the safety status, reliability, and efficiency of the operation.

[0027] As shown in the figure, this is an adaptive portable high-voltage testing wiring device according to an embodiment of the present invention. The device mainly includes an insulated telescopic rod 16, a clamping module, and a polishing module 12. The insulated telescopic rod 16 serves as the support and operating part, enabling remote operation at a safe distance. The clamping module and the polishing module 12 are integrated and mounted on the top of the insulated telescopic rod 16. The clamping module is used to clamp the conductor under test, and the polishing module 12 is used to remove the oxide layer or paint from the conductor surface. The detection end of the acoustic-optical voltage detection module 6 is electrically connected to the clamping module for real-time sensing of the electrical status. The control module is electrically connected to the acoustic-optical voltage detection module 6, the driving component of the clamping module (such as an electric push rod 5), and the polishing module 12, respectively, and is responsible for receiving signals, making judgments, and issuing control commands.

[0028] like Figure 3 As shown, in this embodiment, the control module specifically implements the safe state operation process: S1. Contact Trigger and Initial Detection. When the operator uses the handheld device to make physical contact between the jaws of the clamping module and the conductor under test, the input port of the control module first receives a contact confirmation signal. This signal may originate from a microswitch integrated inside the jaws or be generated by a circuit that detects the continuity of the loop between the jaws and the conductor. This contact confirmation signal serves as the primary trigger condition, and the control module then sends a start command to the audible and visual voltage detection module 6 via its internal control bus to initiate the initial electrical condition detection.

[0029] S2. Safety Status Determination and Path Selection. During the detection phase, the control module simultaneously receives two analog or digital signals from the acoustic-optical voltage detection module 6. These two signals include a voltage detection signal and a micro-current continuity detection signal. The voltage detection signal reflects the potential difference between the conductor and ground or between phases, used to determine whether it is energized. The micro-current continuity detection signal reflects the loop resistance between the clamp and the conductor when a small test current is applied, used to assess the surface insulation condition (such as the presence and thickness of oxide and paint layers).

[0030] The core processing unit of the control module (such as a microcontroller (MCU) calls a built-in safety state determination algorithm to compare the input signal with preset thresholds in real time. It compares the voltage signal with the safety state voltage threshold (e.g., 12V) and the danger state voltage threshold (e.g., 36V); simultaneously, it compares the resistance value calculated from the micro-current signal with the high-resistance insulation threshold. If the voltage signal is lower than the safety state voltage threshold and the micro-current detection indicates that the loop resistance is higher than the high-resistance insulation threshold (in an insulation state), it is determined to be in an initial safe state. If the voltage signal is higher than the danger state voltage threshold or the micro-current signal shows abnormal low-resistance weak conduction (i.e., an unreliable state of partial conduction), it is immediately determined to be in a danger state.

[0031] If a dangerous situation is determined, the control module immediately executes alarm output and hard lockout output. In the alarm output, the audible and visual alarm unit is driven from the alarm output port to emit a high-frequency visual (rapidly flashing red light) and audible (rapid buzzing) alarm. In the hard lockout output, a hard lockout signal (such as a continuous low level) is sent from the control output port to the motor drive circuit of the grinding module 12 and the electric push rod 5 drive circuit of the clamping module, physically cutting off their power supply circuit, rendering all subsequent operation commands invalid, and forcibly interrupting the process.

[0032] If the initial safe state is determined, the control module outputs a signal from the status indicator port to light up the green safe status indicator, indicating that the device has entered the standby state.

[0033] S3, Polishing Execution and Re-verification In standby mode, the control module waits for and receives grinding start commands from the operator via local buttons or wireless remote control. Upon receiving the command, the control module does not act immediately, but instead quickly polls the real-time signal of the audible and visual voltage detection module 6 again to perform a momentary secondary safety status confirmation in case the status changes during the standby period.

[0034] After confirming the safety status twice, the control module sends an enable signal to the motor driver of the grinding module 12 and outputs a specific PWM (pulse width modulation) signal to control the motor to start at a preset optimized speed and begin automatic grinding and cleaning of the conductor contact surface.

[0035] The completion of the grinding operation can be determined in either of the following ways and used as input to the control module: First, timed control, based on a preset grinding duration timer. Second, feedback judgment, monitoring signals from the pressure sensor; when the contact force feedback stabilizes, grinding is considered complete.

[0036] After the grinding process is completed, the control module automatically initiates secondary electrical status detection. During this detection, the control module focuses on analyzing the micro-current continuity detection signal to accurately calculate the contact circuit resistance value after grinding. The processing logic compares this resistance value with a preset, more stringent continuity threshold (e.g., less than 1 milliohm).

[0037] If the resistance value is below the good conduction threshold, the control module determines that the conduction performance is excellent. Subsequently, it outputs a command to drive the electric push rod 5 to execute the final clamping procedure. This procedure may include a closed-loop control sub-process based on real-time feedback from pressure sensor signals to stabilize the clamping force within the set range, and finally activate the mechanical self-locking mechanism inside the push rod.

[0038] If the resistance value is higher than the threshold, the control module determines that the polishing is insufficient or the contact is poor. Its output includes triggering a prompt audible and visual alarm (such as a flashing yellow light or intermittent buzzing) and maintaining the lock on the final clamping command, waiting for operator intervention to check.

[0039] S4. Data Recording and Communication. Throughout the entire work cycle, the control module writes all critical input signals, processing results (such as safety / hazard status indicators, measured voltage and resistance values ​​for each test), and output command sequences into its internal or external non-volatile memory in real time, forming a complete electronic work log. This data can be uploaded to the background management system as needed via its communication port (such as RS-485, CAN bus, or wireless module), enabling traceability and intelligent management of the work process.

[0040] S5. Work Completion and System Reset. After the test is completed, the operator issues a release command. Upon receiving the command, the control module outputs a control signal to drive the electric push rod 5 to release the mechanical self-lock and retract to the fully open position. Subsequently, the control module clears all internal status flags and temporary variables, and restores all output ports to their initial states, awaiting the start of the next work cycle.

[0041] Application Examples The following example illustrates the application process and advantages of this invention by taking a typical scenario of testing the loop resistance of a circuit breaker installed on a support about 5 meters high in a 220kV substation.

[0042] Scenario Overview: One phase terminal block of the circuit breaker under test is located approximately 5 meters above the ground. Due to long-term operation, a dense, dark oxide film has formed on the surface of its copper terminal block, and it may also be contaminated with a small amount of dust. The insulation properties of this oxide film will directly lead to abnormally high circuit resistance test values, and it must be removed before testing. The site environment may have nearby live equipment, and the safety distance may be limited.

[0043] (1) Personnel and preparation: Only one operator is required to operate on the ground. Prepare one adaptive portable high-voltage test wiring device as described in this invention.

[0044] (2) Work process: ① Positioning and Contact: The operator extends the insulated telescopic rod 16 of the device to a suitable length, fine-tunes the jaw posture through the angle adjustment mechanism at the top of the rod, and aligns it with and contacts the circuit breaker terminal block.

[0045] ② One-button start and safety interlock: The operator presses the start button on the handle. The internal control logic of the device operates automatically. Automatic voltage detection: The audible and visual voltage detection module 6 starts immediately to perform the initial test. If any dangerous voltage condition (such as exceeding 36V) is detected, the device will immediately sound an audible and visual alarm and lock all power outputs to prevent misoperation from the source.

[0046] Adaptive clamping and polishing: After confirming a safe state (voltage below 12V and initial resistance extremely high), the control module first instructs the electric push rod 5 to drive the jaws to clamp the terminal block with a constant and appropriate initial force, and then starts the polishing module 12. The polishing head 13 operates at a preset speed, and the device may automatically adjust its posture based on slight vibration feedback.

[0047] ③ Closed-loop verification and reliable connection: After the grinding timer ends, the control module automatically performs a secondary electrical status check. This time, the micro-current detection unit accurately measures the contact resistance after grinding. Only when the resistance value is lower than the set good conduction threshold (e.g., 1 milliohm) will the control module determine that it is qualified and instruct the electric push rod 5 to perform the final precision clamping with pressure feedback closed-loop control until the optimal clamping force is reached and mechanical self-locking is achieved.

[0048] (3) Testing and Recovery: After the operator observes the indicator light on the device (green light is always on) and receives the completion prompt, they can start operating on the testing instrument. After the test is completed, send a release command via the remote control or handle button, and the device will automatically unlock, release the jaws, and reset.

[0049] Therefore, according to the embodiments of the present invention, in terms of safety, it fundamentally transforms high-risk operations such as climbing and manual grinding into remote automated operations on the ground. By utilizing the core detection-judgment-prohibition hardware safety interlock logic, the possibility of accidental contact with live parts is completely eliminated from a physical mechanism, achieving an inherently safer state. In terms of efficiency, the device supports single-person operation, integrating multiple discrete processes such as voltage testing, grinding, verification, and clamping into a continuous automated process. This significantly reduces the wiring preparation time, which traditionally takes 20-30 minutes, to less than 5 minutes, greatly improving work efficiency. In terms of reliability, the unique post-grinding secondary verification process combined with adaptive force control clamping technology ensures low and stable contact resistance for every connection, fundamentally improving the accuracy and repeatability of test data and guaranteeing the reliability of test results. Finally, in terms of convenience, the highly integrated design greatly reduces the types and number of tools required, while the automated process reduces the stringent reliance on the operator's personal skills and experience, making the operation easier to standardize and popularize.

[0050] In this embodiment, specifically, the clamping module preferably includes an upper terminal 1 and a lower terminal 9. The upper terminal 1 is fixed to the top of the insulating telescopic rod 16 by a fixing member, and the upper terminal 1 is provided with upper jaw teeth 2; the lower terminal 9 is fixed to the top of the insulating telescopic rod 16 by a movable member, and the lower terminal 9 is provided with lower jaw teeth 3. The two are precisely linearly opened and closed by a guide rail slide assembly. Specifically, the movable member includes a guide rail slide 7 and a slider 8 slidably disposed on the guide rail slide 7, and the lower terminal 9 is disposed on the slider. Crucially, an elastic pad 4 is embedded between the upper jaw teeth 2 and the lower jaw teeth 3. When the jaws are closed, this elastic structure allows the upper and lower jaw teeth 3 to adaptively fine-tune their angles within a certain range, thereby tightly fitting conductors of different thicknesses or with uneven surfaces, ensuring uniform contact pressure distribution. The effect is to significantly reduce and stabilize contact resistance, improving the reliability of the electrical connection.

[0051] In this embodiment, specifically, the acoustic-optical voltage detection module 6 preferably integrates a voltage detection unit and a micro-current continuity detection unit. The control module is configured to comprehensively process these two signals: voltage detection is used to directly determine whether the conductor is energized, preventing the risk of electric shock; micro-current continuity detection is used to assess the insulation status of the contact surface under low voltage, identifying false insulation caused by oxide layers or paint. The effect is to construct a dual safety criterion, making the voltage detection results more comprehensive and reliable, and avoiding the blind spots that may exist with single detection.

[0052] In this embodiment, specifically, an adaptive portable high-voltage test wiring device further includes an ambient light sensor, an auxiliary lighting unit, an angle adjustment mechanism, and a vibration monitoring module; An ambient light sensor and an auxiliary lighting unit are provided. The ambient light sensor senses the intensity of ambient light during operation, and the control module controls the auxiliary lighting unit to automatically turn on when there is insufficient light, providing supplementary lighting for the working area of ​​the grinding module. An angle adjustment mechanism is located at the top of the insulating telescopic rod and includes a plum blossom joint and a butterfly locking screw, used to manually adjust the pitch angle of the clamping module; A vibration monitoring module is mounted on the fixed bracket of the grinding module or the clamping module, and is used to detect abnormal vibrations during operation; The control module is configured to: transmit device status information, including data from the vibration monitoring module, via the wireless communication module; when the vibration monitoring module detects abnormal vibration exceeding a threshold, the control module can reduce the rotation speed of the grinding module or trigger an alarm.

[0053] In this embodiment, specifically, to further optimize the clamping quality, a pressure sensor can be installed on the drive chain or jaws of the electric push rod 5. During the final clamping stage, the control module can dynamically adjust the output of the electric push rod 5 based on the real-time pressure signal fed back by the sensor, achieving closed-loop control of the clamping force. The effect is that the clamping force can be precisely controlled within the optimal range, preventing damage to the device terminals due to excessive tightness and avoiding poor contact due to excessive looseness, thus achieving refined and adaptive clamping.

[0054] In this embodiment, specifically, the device can be further equipped with a wireless transmission module (such as Wi-Fi or Bluetooth). Through this module, the operator can use a handheld terminal for remote control operation and receive real-time status information, detection data (such as voltage and resistance values), and alarm information transmitted back from the device. This not only increases operational convenience and safety, but also provides a foundation for data recording, traceability, and intelligent management of the operation process.

[0055] In this embodiment, specifically, to address complex spatial angles on-site, the grinding module 12 can be mounted via an adjustable mounting bracket 14. The grinding head 13 is mounted at different positions on the insulating telescopic rod 16 via a butterfly locking screw 11 and the mounting bracket 14, facilitating adjustments to the relative position between the grinding head 13 and the clamping module, thus coordinating grinding and inspection. Simultaneously, an angle adjustment mechanism consisting of a star connector 10 and a butterfly locking screw 11 can be provided at the top of the insulating telescopic rod 16, allowing the clamping module to assume different angular postures relative to the top of the insulating telescopic rod 16. The combined effect of these designs is to endow the device's end effector with flexible posture adjustment capabilities, greatly enhancing the device's adaptability to different installation positions and wiring directions, and broadening its application scenarios.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this application.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
