Description

Technical Field

[0001] The invention relates to the technical field of discharge rods, and in particular to a novel intelligent double-ended discharge rod. Background Art

[0002] In the power system, capacitor banks are one of the important primary equipment in substations and are widely used in voltage regulation and reactive power compensation. Due to the energy storage characteristics of capacitors, each capacitor unit must be thoroughly discharged before power outage inspection or maintenance to ensure that there is no residual charge, thereby ensuring the safety of the staff.

[0003] There are certain limitations in the design of traditional 10kV and 35kV capacitor discharge rods, including but not limited to the following aspects:

[0004] Single-pole discharge limitation: Traditional discharge rods are usually designed with hooked ends, which can only discharge one pole of the capacitor to the ground. When it is necessary to discharge a bipolar capacitor or other similar equipment (such as a capacitor voltage transformer), the operator has to use two discharge rods to contact the two poles of the capacitor at the same time, which not only increases the complexity of the operation, but also increases the safety risk.

[0005] Lack of residual voltage detection function: Existing discharge rods generally lack the function of displaying or judging the residual voltage of capacitors. If the residual voltage in the capacitor is still high and is not discovered in time due to improper operation, large capacity of the tested equipment, insufficient discharge time or environmental factors, it may bring potential electric shock hazards to operators.

[0006] Unstable physical connection: Due to the hook-shaped design at the front end, this structure may not be well adapted to all types of capacitor port layouts, and it is easy to be loosely connected. Especially during the discharge process, if it becomes loose, it may cause an accident.

[0007] In summary, the tools used for capacitor discharge in the prior art have significant operational inconveniences and safety hazards. Summary of the invention

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0040] Example 1

[0041] Reference Figure 1-3, which is the first embodiment of the present invention, provides a new type of intelligent double-end discharge rod, including a rod body 100 and an electric operating member 200 installed on the rod body 100, the rod body 100 includes a hand-held portion 101 and two telescopic portions 102 symmetrically installed at one end of the hand-held portion 101, and each telescopic portion 102 is provided with a clamping member 103 for fixing a capacitor; the electric operating member 200 includes a discharge module 201 and an electric testing module 202 installed on the rod body 100, the discharge module 201 is used to discharge the capacitor, and the electric testing module 202 is used to detect the stored power of the capacitor.

[0042] It should be noted that: Rod body 100: The hand-held portion 101 of the rod body 100 provides a gripping portion for the operator to ensure that the entire tool can be stably controlled during use. Two telescopic portions 102 are symmetrically installed at one end of the hand-held portion 101. Each telescopic portion 102 can be telescoped and locked step by step, similar to the form of a fishing rod. This design allows the operator to adjust the length according to actual needs to adapt to capacitors of different heights and positions. Each telescopic portion 102 is provided with a clamping piece 103 for fixing the capacitor, and a monkey-head double-spring structure hook 103b is used. This design ensures that during the discharge process, the clamping piece 103 can firmly contact the two ends of the capacitor to avoid loosening or falling off, thereby improving the safety and stability of the operation.

[0043] Power operating part 200: The discharge module 201 installed on the rod body 100 includes a direct discharge circuit and a resistance discharge circuit. By switching the switch 201a, the operator can choose direct discharge (fast discharge) or damped discharge (slow discharge) to adapt to different discharge requirements. This design not only improves the flexibility of operation, but also enhances safety. The power test module 202 is used to detect the residual voltage in the capacitor. It includes a step-down device, an analog-to-digital converter, a processor, a buzzer and a warning light. The power test module 202 can monitor the status of the capacitor in real time, and prompt the operator whether the capacitor has been fully discharged through sound and light alarms, thereby further ensuring operational safety.

[0044] The effects are: 1. Improved safety: Double clamping: The double-end design allows the operator to discharge both poles of the capacitor at the same time, reducing the risk of the traditional single-end discharge rod requiring manual operation of two discharge rods. Real-time monitoring: The test module 202 can detect the residual voltage in the capacitor in real time and remind the operator through sound and light alarms to ensure that subsequent operations are carried out under safe conditions. Reliable locking mechanism: The step-by-step locking mechanism of the telescopic part 102 ensures that there will be no accidental sliding during use, increasing the safety of operation. 2. Enhanced efficiency: Fast switching mode: By simply switching the switch 201a, the operator can quickly switch between direct discharge and resistance discharge modes without replacing the grounding wire 101b, greatly improving work efficiency. Flexible adjustment: The design of the telescopic part 102 enables the discharge rod to adapt to capacitors of different heights and positions, reducing the need for ladders or other auxiliary equipment and improving the flexibility of operation. 3. Convenience and portability: Integrated design: All functional modules (discharge module 201 and test module 202) are installed on the rod body 100, reducing the trouble of carrying multiple independent tools and facilitating carrying and storage. Reel 101a: The reel 101a arranged on the outside of the handheld part 101 is used to wind and manage the ground wire 101b, so that the ground wire 101b can be stored in an orderly manner, which is convenient for quick retraction and release, and reduces the risk of line clutter and knotting. 4. Strong adaptability: Widely applicable: This design is not only suitable for 10kV and 35kV capacitor banks, but also can adjust parameters as needed and be applied to equipment of other voltage levels, with strong versatility and adaptability. Environmental tolerance: Considering the special working environment of the power system, the discharge rod usually has a certain level of protection, such as waterproof, dustproof and other characteristics, to ensure normal operation under various harsh conditions.

[0045] Each telescopic portion 102 is configured to be L-shaped, and its two sections are configured to be in the form of multi-stage telescopic rods, and the corners are hinged and bendable.

[0046] It should be noted that: each telescopic part 102 is composed of two sections, forming an L-shape. This design allows the discharge rod to be operated in different directions and adapt to more complex working environments. The telescopic part 102 is telescopic in a step-by-step manner in the form of a fishing rod, and is maintained in an extended state by the friction between the sleeves. When the sleeve is pulled out, the internal friction material (such as a rubber gasket) increases the friction to keep the sleeve in its current position. The corner part of the L-shape adopts a hinged design, allowing the two sections of the telescopic part 102 to bend within a certain angle range. This design increases the overall flexibility of the discharge rod, allowing it to be used more conveniently in confined spaces. Bendable: Through the hinged design, the telescopic part 102 can be folded up when not in use, reducing the overall volume and facilitating storage and carrying.

[0047] The effects are: Enhanced portability: Reduced volume: When not in use, the telescopic portion 102 can be completely retracted, and the L-shaped structure can be folded into a more compact shape through the hinge design, which greatly reduces the overall volume of the discharge rod, making it easier to put into a tool box or backpack for easy carrying. Easy to store: The folded discharge rod takes up less space and is suitable for storage in limited spaces, such as vehicle trunks, tool rooms, etc.

[0048] Operational flexibility: Adaptable to various environments: The L-shaped design and multi-stage telescopic rod enable the discharge rod to adapt to a variety of different working environments, including high places, narrow spaces and complex layouts of power equipment. Flexible adjustment: The hinged design allows the operator to adjust the angle of the telescopic part 102 according to the on-site conditions, so as to better contact the capacitor and ensure that the clamping piece 103 is firmly fixed on the capacitor.

[0049] The clamping member 103 comprises a universal joint 103a installed at one end of the telescopic part 102, and a monkey-head double-spring structure hook 103b arranged on the universal joint 103a. A symmetrical metal clip 103c is arranged inside the monkey-head double-spring structure hook 103b.

[0050] It should be noted that the design of the clamp 103 significantly improves the flexibility, stability and reliability of operation by combining the universal joint 103a and the monkey-head double-spring structure hook 103b. The universal joint 103a allows the hook to rotate freely in multiple directions, so that the operator can easily align and fix it at different positions of the capacitor, which is particularly suitable for environments with limited space or complex angles. The symmetrical metal clips 103c inside the monkey-head double-spring structure hook 103b provide a strong clamping force to ensure that it will not loosen or fall off during the discharge process, while ensuring a good electrical connection and reducing safety risks caused by poor contact. The overall design not only improves the convenience and safety of operation, but also enhances the applicability and durability of the clamp 103 in a variety of application scenarios.

[0051] Example 2

[0052] Reference Figure 1-4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the electrical test module 202 is installed on the rod body 100, and its input end is electrically connected to the metal clip 103c. The electrical test module 202 includes a voltage reducer, an analog-to-digital converter, a processor, a buzzer, and a warning light. One end of the voltage reducer is connected to the clamp 103, and the other end of the voltage reducer is connected to the input end of the analog-to-digital converter. The output end of the analog-to-digital converter is connected to the processor, and the processor is connected to the buzzer and the warning light.

[0053] It should be noted that the test module 202 is mounted on the rod body 100 of the discharge rod to ensure that the operator can easily observe its status. The input end of the test module 202 is electrically connected to the metal clip 103c (i.e., the conductive part inside the monkey-head double-spring structure hook 103b for contacting the capacitor). This means that when the metal clip 103c contacts the capacitor, the voltage on the capacitor will be transmitted to the test module 202 through this connection.

[0054] Components and connections of the voltage test module 202: (1) Voltage reducer: One end of the voltage reducer is directly connected to the clamp 103 (i.e., the metal clip 103c), and the other end is connected to the input of the analog-to-digital converter. The function of the voltage reducer is to reduce the high-voltage signal obtained from the capacitor to a safe voltage level suitable for subsequent circuit processing. This is crucial to protect subsequent electronic components from damage. (2) Analog-to-digital converter (ADC): The analog-to-digital converter receives the low-voltage analog signal from the voltage reducer and converts it into a digital signal. In this way, the processor can read and process the data. The output of the ADC is connected to the processor for data transmission. (3) Processor: The processor is responsible for receiving the digital signal transmitted by the analog-to-digital converter and analyzing and processing the data. The processor determines whether the capacitor has been fully discharged based on a preset safety threshold. If the detected voltage exceeds the safety range, the processor will trigger the corresponding warning mechanism. (4) Buzzer and warning light: The processor is connected to the buzzer and warning light. When the processor determines that there is still a high residual voltage in the capacitor, it will activate the buzzer to sound an alarm and light up the warning light to provide a visual warning. On the other hand, if the capacitor is fully discharged, the processor turns off the buzzer and warning light.

[0055] Effects and advantages of the electrical testing module 202:

[0056] 1. Real-time voltage detection: Instant feedback: When the metal clip 103c contacts the two ends of the capacitor, the voltage reducer will immediately start processing the voltage signal from the capacitor. After the voltage reduction process, the analog-to-digital converter quickly converts the analog signal into a digital signal and transmits it to the processor for analysis. Continuous monitoring: During the entire discharge process, the power detection module 202 can continuously monitor the voltage changes on the capacitor to ensure real-time understanding of the capacitor's status.

[0057] 2. Efficient data processing: Fast response: The processor processes the received data quickly and can complete the evaluation of the capacitor status in a short time. This reduces waiting time and improves work efficiency. Accurate judgment: Through the preset safety thresholds, the processor can accurately judge whether the capacitor has been fully discharged. These thresholds can be adjusted according to different application scenarios and standards to adapt to different types of capacitors and their specific safety requirements.

[0058] 3. Multiple warning mechanisms: Auditory alarm: If the processor detects that there is still a high residual voltage in the capacitor, the buzzer will be activated and an audible alarm will sound. This auditory alarm can immediately attract the operator's attention and effectively convey information even in a noisy working environment. Visual prompt: At the same time, the warning light will also be illuminated, providing an obvious visual signal. The combination of vision and hearing ensures that the operator can get a timely warning even when one or more senses are limited.

[0059] 4. Improve safety: Prevent electric shock accidents: Through effective voltage detection and multiple warning mechanisms, the power test module 202 significantly reduces the risk of electric shock to operators due to incomplete discharge of capacitors. Only after confirming that the capacitor has been safely discharged will the operator continue with subsequent maintenance work. Reduce human errors: Traditional manual detection methods rely on the operator's experience and technical level and are prone to misjudgment. The power test module 202 provides objective data support and reduces the uncertainty caused by subjective factors.

[0060] 5. Enhanced user experience: Intuitive display: Further designs may also be equipped with an LCD display or other visual interface to directly display the current voltage value of the capacitor, allowing operators to more intuitively understand the status of the capacitor. Easy to use: The design of the entire device takes into account the ease of operation, and even non-professionals can easily get started. The monkey-head double-spring structure of the metal clip 103c ensures good contact stability and avoids the common problem of unstable hanging in traditional hook designs.

[0061] 6. Strong adaptability: Widely applicable: The power test module 202 is not only suitable for 10kV and 35kV capacitor banks, but can also be used for equipment of other voltage levels according to the need to adjust parameters, and has strong versatility and adaptability. Environmental tolerance: Considering the special working environment of the power system, the power test module 202 usually has a certain level of protection, such as waterproof and dustproof, to ensure normal operation under various harsh conditions.

[0062] It can be seen from the above description that the power test module 202 greatly improves the safety and efficiency of the capacitor discharge process through its advanced circuit design and multiple safety measures. This innovative technical solution has brought substantial improvements to the maintenance of the power system.

[0063] In this embodiment, when the two ends of the discharge rod of the present application are connected to different positions on the capacitor, the capacitor is tested for electricity when it is discharged. The specific process is: the metal clip 103c inside the monkey-head double-spring structure hook 103b that is hooked and clamped on the capacitor is in contact with the capacitor and electrically connected to it, so as to sample the voltage of the capacitor. Since the test module 202 is electrically connected to the metal clip 103c, after the test module 202 is powered on, the voltage signal introduced is firstly reduced by taking appropriate voltage division through the step-down device; then, the analog voltage signal after the voltage reduction is converted into a digital signal through the analog-to-digital converter (ADC); finally, the processor receives these digital signals and calculates the actual voltage value of the capacitor. If it is detected that there is still a lot of voltage remaining inside the capacitor, that is, when it exceeds the safe working threshold, the buzzer and the warning light remain on; on the contrary, when the voltage in the capacitor is lower than the safe threshold, the buzzer stops sounding and the warning light turns off.

[0064] The remaining structures are the same as those of Example 1.

[0065] Example 3

[0066] Reference Figure 1-2 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the telescopic part 102 is set to an insulating material, and a cable 102a is set inside the telescopic part 102, and a resistor 102c is also set inside the telescopic part 102. A switch 201a of a discharge module 201 is set on the telescopic part 102. The discharge module 201 includes a resistance-release circuit and a direct-release circuit inside the telescopic part 102. The direct-release circuit is composed of a clamping part 103 and a cable 102a, and the resistance-release circuit is composed of a clamping part 103, a cable 102a, and a resistor 102c. A ground terminal 102b is set at one end close to the handheld part 101.

[0067] It should be noted that the telescopic part 102 is made of insulating material to ensure that the operator will not get an electric shock accident due to contact with the telescopic part 102 during use. The insulating material can be plastic, rubber or other composite materials with high insulation performance.

[0068] The telescopic part 102 is internally arranged as follows: The first section of the cable 102a extends from the clamp 103 (the monkey-head double-spring structure hook 103b) to the inside of the telescopic part 102. The position of the resistor 102c: The resistor 102c is installed inside the telescopic part 102 and is located in the path of the cable 102a. The function of the resistor 102c is to limit the current in the damping discharge mode, thereby controlling the discharge rate. The resistor 102c is arranged in parallel with the switch 201a. When the switch 201a is closed, the current directly flows to the second section of the cable 102a; when the switch 201a is opened, the current passes through the resistor 102c and then to the second section of the cable 102a. The switch 201a is arranged on the telescopic part 102, so that the operator can manually switch between the direct discharge mode and the resistance discharge mode. When the switch 201a is closed, the current flows directly to the third cable 102a through the second cable 102a, so as to achieve rapid discharge (direct discharge); open state: when the switch 201a is opened, the current is forced to pass through the resistor 102c, and then flows to the third cable 102a, so as to achieve slow discharge (resistance discharge). The second cable 102a: extends from the switch 201a or the resistor 102c (depending on the state of the switch 201a) to the ground terminal 102b.

[0069] Direct-release loop: It is composed of the clamping member 103, the first cable 102a, the switching switch 201a in the closed state and the second cable 102a. In the direct-release mode, the current is discharged directly through these cables 102a.

[0070] Resistance-discharge circuit: It is composed of the clamping member 103, the first cable section 102a, the resistor 102c and the second cable section 102a. In the resistance-discharge mode, the current is discharged through the resistor 102c, thereby slowing down the discharge rate.

[0071] The grounding terminal 102b is arranged at one end of the telescopic part 102 close to the handheld part 101. The grounding terminal 102b is used to connect the grounding wire 101b to safely conduct the charge to the ground. Whether in direct discharge mode or resistance discharge mode, the grounding terminal 102b always provides a reliable grounding path to ensure that the charge in the capacitor can be completely discharged.

[0072] Advantages of the switching switch 201a: (1) Quick and convenient: With a simple switching switch 201a, the operator can quickly switch between direct discharge and blocking discharge modes without removing or reconnecting the ground wire 101b. This design significantly improves the convenience and efficiency of operation. (2) Reduce errors: The traditional practice is to select different discharge modes by manually replacing the ground wire 101b, which increases the complexity of operation and the possibility of errors. The use of switching switch 201a avoids these potential problems and reduces operational risks. (3) Improve work efficiency: The operator can complete the mode switching in a few seconds, greatly shortening the discharge preparation time and improving overall work efficiency. Enhanced user experience: The simple and intuitive design makes it easy for non-professionals to operate, enhancing the user experience.

[0073] Safety and reliability: Multiple protections: Whether in direct discharge or blocking discharge mode, the ground wire 101b is always reliably connected to ensure that the charge can be safely introduced into the ground to prevent accidental electric shock. Protective measures: It is recommended that operators wear appropriate personal protective equipment, such as insulating gloves and protective glasses, to further ensure safety.

[0074] A reel 101a is disposed outside the handheld portion 101. A grounding wire 101b is wound around the reel 101a. One end of the grounding wire 101b is connected to a grounding terminal 102b and the other end is grounded. The reel 101a includes a fixed plate and a turntable rotatably mounted on the fixed plate. A handle is disposed on the end surface of the turntable.

[0075] It should be noted that a winding wheel 101a is provided on the outside of the handheld portion 101, which is similar to the handwheel on a fishing rod and is used to wind up the grounding wire 101b to achieve a moderate release of the grounding wire 101b. Specifically: the fixed plate is the basic structure of the winding wheel 101a, which is usually installed on the outside of the handheld portion 101. It provides stable support to ensure that the winding wheel 101a will not loosen or fall off during use. The turntable is the core component of the winding wheel 101a, which is used to wind the grounding wire 101b. The turntable is mounted on the fixed plate through a bearing or other rotating device so that it can rotate freely. The handle is set on the end face of the turntable to facilitate the operator to manually rotate the turntable to retract and release the grounding wire 101b. The design of the handle should be ergonomic to ensure comfortable grip and easy operation.

[0076] Grounding wire 101b: One end of the grounding wire 101b is connected to the grounding terminal 102b (i.e. the grounding terminal 102b on the discharge rod), and the other end is grounded. The function of the grounding wire 101b is to safely guide the charge in the capacitor to the ground to ensure the safety of the operation.

[0077] The grounding wire 101b is wound on the turntable, and the grounding wire 101b can be wound or released by manually rotating the handle. This can prevent the grounding wire 101b from being scattered when not in use, and reduce the risk of winding and knotting. By rotating the handle, the operator can adjust the length of the grounding wire 101b according to actual needs to meet the grounding needs of different heights and positions.

[0078] The advantages of this setting are: (1) Convenience: The reel 101a makes the management and use of the grounding wire 101b more convenient. The operator can quickly retract and release the grounding wire 101b, reducing the time for wiring and sorting. (2) Safety: The grounding wire 101b is stored in an orderly manner, reducing the risk of tripping or electric shock caused by messy wires. (3) Durability: The design of the reel 101a protects the grounding wire 101b, reduces the possibility of wear and damage, and extends the service life of the grounding wire 101b. (4) Cleanliness: The reel 101a keeps the overall cleanliness of the tool and makes the working environment more orderly.

[0079] Operation method: Release: When the grounding wire 101b is needed, the operator holds the handle and rotates it counterclockwise to release the grounding wire 101b. The grounding wire 101b will gradually unfold from the turntable until it reaches the required length. Rewind: After completing the discharge operation, the operator holds the handle and rotates it clockwise to rewind the grounding wire 101b onto the turntable. The rotation speed should be moderate to prevent the grounding wire 101b from being wound too tight or too loose.

[0080] In this embodiment, when direct discharge is adopted (direct discharge), the monkey-head double-spring structure hook 103b is clamped on the capacitor, and the metal clip 103c in the hook contacts the capacitor and establishes an electrical connection. When discharging, the charge in the capacitor flows through the following path: starting from the capacitor, through the metal clip 103c, through the first cable 102a inside the telescopic part 102, through the closed switch 201a (at this time, the switch 201a is in a closed state, allowing current to pass directly), through the second cable 102a, to the ground terminal 102b, and finally through the grounding wire 101b connected to the ground terminal 102b to introduce the charge into the ground, completing the direct discharge operation.

[0081] Direct discharge effect: Rapid discharge: Since there is no restriction of resistor 102c, the charge in the capacitor can be released quickly, which is suitable for situations where rapid discharge is required. Simple and efficient: The operator only needs to clamp the hook on the capacitor and put the switch 201a in a closed state to achieve rapid discharge, simplifying the operation steps. Reduced misoperation: There is no need to manually change the position of the ground wire 101b, which reduces misoperation that may be caused by frequent replacement of the ground wire 101b.

[0082] When the damped discharge mode is adopted (damped discharge), the monkey-head double-spring structure hook 103b is also clamped on the capacitor, and the metal clip 103c in the hook contacts the capacitor and establishes an electrical connection. When discharging, the charge in the capacitor flows through the following path: starting from the capacitor, through the metal clip 103c, through the first cable 102a inside the telescopic part 102, through the resistor 102c (at this time, the switch 201a is in the open state, so that the current must pass through the resistor 102c), through the second cable 102a, to the ground terminal 102b, and finally through the grounding wire 101b connected to the ground terminal 102b to introduce the charge into the ground, completing the damped discharge operation.

[0083] Discharge resistance effect: Controlling the discharge rate: The presence of resistor 102c slows down the discharge rate, which helps control the energy release speed in the capacitor, reduces transient shocks, and protects equipment and personnel safety. Prolonging service life: The slow discharge process can reduce the thermal stress on capacitors and other electrical equipment, thereby extending their service life. Improving safety: Discharging through resistor 102c can reduce the risk of arcing during the discharge process and improve the safety of operation.

[0084] The remaining structure is the same as that of Example 2.
