Description

Technical Field

[0001] This invention relates to the field of switchgear testing technology, specifically to a switchgear fault detection device with a modular testing unit. Background Technology

[0002] Switchgear is a key device in power systems used for control, protection and isolation of circuits. Its operational reliability is directly related to the safety and stability of the entire power grid. Therefore, it is essential to regularly detect faults in switchgear. Traditional switchgear testing methods usually rely on manual operation. Testers need to use general instruments such as multimeters and oscilloscopes to manually touch the terminals of the equipment to measure parameters such as voltage, current and resistance, and manually operate the switch buttons to check its switching function.

[0003] This manual inspection method has many drawbacks: First, it is inefficient, heavily reliant on the experience and skill of operators, making it difficult to achieve batch and standardized operations. Second, it poses significant safety hazards, as operators must directly contact live parts during inspection; if the equipment is not completely de-energized or misoperation occurs, electric shock accidents are highly likely. Third, the force and travel of manually pressing the switch button are difficult to control precisely, and the action time of the switch button cannot be quantified and recorded, lacking objective and accurate evidence for judging whether the switch button has hidden faults such as jamming or corrosion. In addition, the wiring terminals of the switch equipment are exposed to the environment for a long time, easily accumulating dust, oil, and other impurities, affecting the reliability of electrical contact; traditional inspection methods lack the function of automatically cleaning the wiring terminals before inspection, which may lead to distorted inspection results.

[0004] To address these issues, some automated testing equipment has emerged on the market. However, most of these devices are complex in structure, have limited functionality, and are typically designed for specific models of switchgear, resulting in poor versatility. When faced with switchgear of different specifications and sizes, different fixtures and testing probes are often required, increasing usage costs and operational complexity. Furthermore, existing equipment still needs improvement in terms of how to safely and securely install it onto the device under test, and how to organically integrate mechanical motion, electrical testing, and safety protection. Therefore, developing a fault detection device for switchgear with a modular structure that can automatically complete fixing, cleaning, electrical signal detection, and mechanical performance evaluation of switch buttons, while also possessing high safety and wide adaptability, is of great practical significance and has an urgent market demand. Summary of the Invention

[0005] The purpose of this invention is to provide a switchgear fault detection device with a modular detection unit to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a switchgear fault detection device with a modular detection unit, comprising a gripping assembly, a pressing assembly disposed at the outer end of the gripping assembly, and a contact assembly connected to the outer end of the pressing assembly; the contact assembly comprising a mating seat, a second electrical control seat disposed inside the mating seat, and a power-conducting seat disposed at the top of the second electrical control seat; a mounting head disposed at the outer end of the mating seat, and a venting groove formed inside the mounting head; an electric push rod disposed inside the mounting head, and a push-out head disposed at the output end of the electric push rod; an insulating block disposed at the middle end of the push-out head; and so on. A third conductive line is provided between the ejector head and the second electrical control base. A detection connector is installed at the outer end of the ejector head, and an air jet groove is opened inside the detection connector. A through groove is opened at the outer end of the detection connector. A fixing component is installed at the outer end of the docking base. The fixing component includes a fixing seat. An exhaust fan is installed inside the fixing seat, and a one-way exhaust valve is installed inside the fixing seat. A suction cup is installed at the outer end of the fixing seat. Elastic plates are installed at both ends of the outer side of the fixing seat, and a clamping seat is fixed at the bottom end of the elastic plate. A connecting groove is opened between the fixing seat and the docking base. A switching device is adsorbed at the outer end of the suction cup.

[0007] Furthermore, the gripping assembly includes a gripping seat, a battery is disposed inside the gripping seat, and a first conductive wire is connected to the outer end of the battery, the end of the first conductive wire being connected to a connecting seat.

[0008] Furthermore, the pressing assembly includes a C-shaped block, with connecting heads at both ends of the rear portion of the C-shaped block. The outer ends of the connecting heads are connected to a second conductive line, and the ends of the second conductive lines are connected to a first electronic control base. Electromagnets are installed at both ends of the top of the first electronic control base. A return spring is installed inside the C-shaped block, and a pressing head is installed at the output end of the return spring. A pressure-sensitive sensor is installed inside the pressing head, and an armature block is installed at the outer end of the pressing head. The end of the second conductive line is connected to a conductive base.

[0009] Furthermore, the battery is connected to the connection socket via the first conductive line, and the connection socket is connected to the first electronic control socket and the connection socket via the connection head and the second conductive line.

[0010] Furthermore, the gripping seat is fixed to the C-block by engaging the connecting seat and the connecting head, and the C-block is fixed to the docking seat by engaging the conducting seat and the second electronic control seat.

[0011] Furthermore, the reset spring is elastically connected to the pressing head, and the pressing head is electromagnetically attracted to the electromagnet via an armature block.

[0012] Furthermore, the switching device includes a body, with a wiring terminal at the outer front end of the body and a switch button at the top front end of the body.

[0013] Furthermore, the suction cup is fixedly connected to the body by adsorption, and the elastic plate is engaged with the body.

[0014] Furthermore, the second electrical control base is connected to the exhaust fan via a power-on base, and the docking base is engaged and fixed with the fixing base via the power-on base.

[0015] Furthermore, the suction cup is connected to the interior of the fixed base via a one-way exhaust valve, and the fixed base is connected to the interior of the docking seat via a connecting groove.

[0016] This invention provides a fault detection device for switchgear with a modular detection unit, which has the following advantages: 1. In this invention, the operator first aligns the testing connector with the wiring terminals on the machine body one by one. Then, the suction cup is attached to the surface of the machine body. The gripping seat contains a battery, whose power is transmitted to the connecting seat via the first conductive line. The connecting seat is connected to the second conductive line through the connecting head, thus leading the power to the connecting seat. Finally, the power is supplied to the exhaust fan through the second electrical control seat and the power supply seat. After the suction cup is firmly attached to the surface of the machine body, the exhaust fan is turned on, which extracts the air from the contact area between the suction cup and the machine body. The extracted gas enters the fixed seat through the one-way exhaust valve, thereby creating a negative pressure between the suction cup and the machine body to ensure a firm adhesion. At the same time, the operator can pull the elastic plate outward to make the clamping seat clamp the edge of the machine body, further enhancing the fixation effect. Through the combined action of the suction cup and the clamping seat, the stability of the equipment during the testing process is effectively improved. After the gas drawn in by the exhaust fan enters the fixed seat, it flows into the docking seat through the connecting groove, and then into the air jet groove through the ventilation groove and the connecting groove, and finally is ejected from the air jet groove. Since the test connector is now aligned with the terminal block, the ejected gas can directly blow onto the terminal block surface. With this design, the equipment can automatically clean the terminal block while it is fixed in place, avoiding dust or impurities and ensuring the accuracy of the test results.

[0017] 2. When the electric actuator of this invention is working, it pushes the push-out head to move, thereby extending the detection connector from the mounting head and making it reliably contact the wiring terminal. The second electrical control base is connected to the detection connector through the push-out head via the third conductive line. When the detection connector touches the wiring terminal, it can collect the electrical signal data of that end, thereby determining whether the switchgear is in a normal state. An insulating block is installed at the end of the push-out head near the electric actuator, which can effectively isolate the electric actuator part and ensure the accuracy of the signal obtained by the third conductive line. After the data acquisition is completed, the electric actuator drives the push-out head to retract, separating the detection connector from the wiring terminal. In the entire operation process, the operator only needs to complete the installation and disassembly of the equipment and does not need to directly contact any live parts. If the switchgear is not powered off, the power is accidentally turned on during the detection process, or there is leakage in the equipment, this design can still effectively ensure the safety of the operator.

[0018] 3. After the detection connector and wiring terminal of this invention are aligned and the device is fixed on the switch, the pressing head is in contact with the switch button. During the detection process of the contact assembly, the first electrical control base is activated, de-energizing the electromagnet on the side of the pressing head facing the switch button. After the electromagnet loses its magnetism, the armature block is no longer attracted, and the return spring then springs the pressing head up, thereby applying a force to the switch button. The return force of the return spring is set to be slightly greater than the required pressing force of the switch button. Therefore, the switch button can be triggered during the return process of the pressing head. After the switch button is pressed, its other end will lift up and contact the pressing head that has not been displaced. If the switch button has problems such as corrosion or jamming, the return spring will... The elastic force will not be able to complete the pressing action smoothly. The pressing head is equipped with a pressure-sensitive sensor, which can determine whether the switch button is working properly by detecting whether a pressure signal is received. In addition, the device can also count the time interval from the electromagnet being de-energized to the pressure-sensitive sensor sensing the pressure. If the time is abnormal, it can be determined that the switch button is blocked. This design allows the device to accurately determine the working status of the switch button without manual intervention, effectively improving the convenience and safety of operation. The pressing component can also work in conjunction with the contact component to control the on and off of the switch button and detect the electrical signal at the terminal to further verify whether the switching device is working properly, thereby enhancing the overall function of the device.

[0019] 4. The gripping component, pressing component, contact component, and fixing component of this invention achieve mechanical docking and electrical connection through the interlocking structure between the components. When performing fault detection on switchgear, since different models of equipment are often involved, the pressing component, contact component, and fixing component can be replaced to adapt to switchgear of different sizes and specifications, significantly broadening the applicability of the equipment. This modular design is also suitable for repeated testing of the same model of switchgear. By replacing the same type of pressing component and contact component, multiple verifications can be performed, which helps to improve the accuracy of the test results. In addition, the battery is integrated inside the gripping component. When the equipment power is insufficient, simply replacing the gripping component can quickly restore power supply, ensuring that the testing work can be carried out continuously for a long time.

[0022] Please see Figures 1 to 7The present invention provides a technical solution: a fault detection device for switchgear with a modular detection unit, comprising a gripping assembly 1, the gripping assembly 1 including a gripping seat 101, a battery 102 disposed inside the gripping seat 101, and a first conductive line 103 connected to the outer end of the battery 102, the end of the first conductive line 103 being connected to a connecting seat 104; a pressing assembly 2 disposed at the outer end of the gripping assembly 1, the pressing assembly 2 including a C-block 201, connecting heads 202 disposed at both ends of the rear part of the C-block 201, and a second conductive line 203 connected to the outer end of the connecting head 202, the end of the second conductive line 203 being connected to a first electrical control seat 204; and the first... Electromagnets 205 are mounted at both ends of the top of an electric control base 204. A return spring 206 is installed inside the C-block 201, and a pressing head 207 is installed at the output end of the return spring 206. A pressure sensor 208 is installed inside the pressing head 207, and an armature block 209 is provided at the outer end of the pressing head 207. A conductive seat 210 is connected to the end of the second conductive line 203. A contact component 3 is connected to the outer end of the pressing component 2. The contact component 3 includes a docking seat 301. A second electric control base 302 is installed inside the docking seat 301, and a power-conducting seat 303 is provided at the top of the second electric control base 302. A mounting head 304 is installed at the outer end of the docking seat 301. Furthermore, the installation head 304 has a ventilation groove 305 inside, an electric actuator 306 is installed inside the installation head 304, and an ejector head 307 is provided at the output end of the electric actuator 306. An insulating block 308 is provided at the middle end of the ejector head 307. A third conductive line 309 is provided between the ejector head 307 and the second electric control base 302. A detection connector 310 is installed at the outer end of the ejector head 307, and an air jet groove 311 is provided inside the detection connector 310. A through groove 312 is provided at the outer end of the detection connector 310. A fixing component 4 is installed at the outer end of the docking base 301. The fixing component 4 includes a fixing base 401, and an exhaust fan 4 is installed inside the fixing base 401. 02, and the fixed base 401 is equipped with a one-way exhaust valve 403 inside, the fixed base 401 is equipped with a suction cup 404 at the outer end, the fixed base 401 is equipped with elastic plates 405 at both outer ends, and the bottom end of the elastic plate 405 is fixed with a clamping seat 406. A connecting groove 407 is opened between the fixed base 401 and the docking seat 301. The outer end of the suction cup 404 is attached to the switch device 5. The switch device 5 includes a body 501. The front outer end of the body 501 is provided with a wiring terminal 502, and the top front end of the body 501 is provided with a switch button 503. The suction cup 404 is attached to the body 501 and fixedly connected. The elastic plate 405 is engaged with the body 501.

[0023] The specific operation is as follows: After the operator disconnects the power to the switchgear 5 to be tested, they hold the gripper 101 to bring the device close to the body 501. The operator aligns the test connector 310 with the wiring terminals 502 of the body 501, then attaches the suction cup 404 to the surface of the body 501. A battery 102 is housed inside the gripper 101, and the battery 102 is connected to the connection seat 104 via the first conductive line 103. The connection seat 104 is connected to the connection head... 202 is connected to the second conductive line 203, which is connected to the second electrical control base 302 via the conductive base 210. The second electrical control base 302 is connected to the exhaust fan 402 via the power-on base 303. After the suction cup 404 is attached to the surface of the body 501, the exhaust fan 402 is powered on and works, which can suck out the air from the attachment point between the suction cup 404 and the body 501, and enter the fixed base 401 through the one-way exhaust valve 403. This allows the suction cup 404 to adhere to the surface of the body 501. A negative pressure can be formed between the suction cup 404 and the body 501 to ensure the adsorption stability between them. In addition, the operator can use the external elastic plate 405 to make the clamping seat 406 clamp the edge of the body 501 for fixation. The double fixation of the suction cup 404 and the clamping seat 406 can effectively ensure the stability of the equipment during the detection process. The gas entering the fixed seat 401 through the exhaust fan 402 can enter the docking seat 301 through the connecting groove 407. After entering the docking seat 301, the gas can flow into the ventilation groove 305. The ventilation groove 305 is connected to the air jet groove 311 through the connecting groove 312, which allows the gas to be ejected from the air jet groove 311. Since the detection connector 310 is aligned with the terminal 502, the gas can be blown onto the surface of the terminal 502 after being ejected. Through this design, the equipment can automatically clean the terminal 502 during the fixation process, avoiding the presence of dust and impurities on the surface of the terminal 502 from affecting the detection accuracy.

[0024] Please see Figures 1 to 4 The battery 102 is connected to the connection seat 104 via the first conductive line 103, and the connection seat 104 is connected to the first electronic control seat 204 and the conductive seat 210 via the connection head 202 and the second conductive line 203. The gripping seat 101 is fixed to the C-block 201 by the engagement of the connection seat 104 and the connection head 202, and the C-block 201 is fixed to the docking seat 301 by the engagement of the conductive seat 210 and the second electronic control seat 302. Spring 206 is elastically connected to pressing head 207, and pressing head 207 is electromagnetically attracted to electromagnet 205 through armature block 209. Second electric control base 302 is connected to exhaust fan 402 through power supply base 303, and docking base 301 is engaged and fixed to fixed base 401 through power supply base 303. Suction cup 404 is connected to the inside of fixed base 401 through one-way exhaust valve 403, and fixed base 401 is connected to the inside of docking base 301 through connecting groove 407. The specific operation is as follows: After the equipment is fixed, the electric push rod 306 drives the push head 307 to move, allowing the detection connector 310 to move out from inside the mounting head 304. This allows the detection connector 310 to contact the terminal 502. The second electrical control base 302 is connected to the detection connector 310 via the third conductive line 309 and the push head 307. When the detection connector 310 contacts the terminal 502, the second electrical control base 302 can obtain the electrical signal data of the terminal 502 through the third conductive line 309, thereby determining whether the switchgear 5 has a fault. An insulating block 308 is provided at the end of the push head 307 near the electric push rod 306. The insulating block 308 can isolate the end of the electric push rod 306, which can ensure the accuracy of information acquisition by the third conductive line 309. After data acquisition, the electric actuator 306 drives the push head 307 to reset, allowing the test connector 310 to separate from the terminal 502. In this process, the operator only needs to fix and remove the equipment without contacting live parts. This greatly improves operator safety, especially when the switch 5 is not powered off during testing, the power is turned on during testing, or there is leakage in the switch 5. After the test connector 310 is aligned with the terminal 502 and the equipment is fixed to the switch 5, the pressing head 207 can contact the switch button 503. During the testing process of the contact component 3, the first electrical control base 204 operates, allowing the pressing head 207 to contact the switch button 503. When the electromagnet 205 on the side is de-energized, the armature block 209 loses its magnetic attraction, and the pressing head 207 is bounced up by the return spring 206. This causes the pressing head 207 to apply force to the switch button 503. The rebound force of the return spring 206 is set to be just greater than the force applied when the switch button 503 is pressed. This allows the pressing head 207 to press and switch the switch button 503 during its rebound. After the switch button 503 is pressed, its other end will bounce up, and the bounced end of the switch button 503 can contact the pressing head 207, which has not moved. If the switch button 503 is corroded or rusted, the rebound force of the return spring 206 will not be enough to press and switch the switch button 503. In addition, a pressure sensor is installed inside the pressing head 207. 208. This design allows the device to determine whether the switch button 503 is faulty by judging whether the pressure sensor 208 senses pressure. Furthermore, the device can calculate the time from the de-energization of the electromagnet 205 to the pressure sensor 208 sensing pressure; if the time is too long, it can determine that the switch button 503 is blocked. This design enables the device to clearly and accurately determine whether the switch button 503 is faulty without manual operation, further improving the ease of operation and safety. In addition, the pressing component 2 can work in conjunction with the contact component 3 to control the on / off state of the switch button 503 to detect the electrical signal at the terminal 502 and determine whether the switching device 5 is working properly, further enhancing the functionality of the device.The gripping component 1, pressing component 2, contact component 3, and fixing component 4 achieve docking and electrical connection through interlocking. During fault detection of the switchgear 5, operators typically test different models of switchgear 5. By replacing the pressing component 2, contact component 3, and fixing component 4, the equipment can adapt to test different sizes and models of switchgear 5, greatly expanding its application range. Furthermore, this modular design allows for retesting even when testing a single model of switchgear 5 by replacing the same type of pressing component 2 and contact component 3, improving the equipment's testing accuracy. Additionally, the battery 102 is integrated inside the gripping component 1; when the equipment has insufficient power, simply replacing the gripping component 1 ensures extended testing operation.

[0025] In summary, this switchgear fault detection device with modular detection units is used by first disconnecting the power to the switchgear 5 to be tested. Then, by holding the gripping seat 101, the operator can bring the device close to the body 501. After aligning the detection connector 310 with the wiring terminals 502 of the body 501, the operator can attach the suction cup 404 to the surface of the body 501. The gripping seat 101 contains a battery 102, which is connected to the connection seat 104 through the first conductive line 103. The connection seat 104 is connected to the second conductive line 203 through the connection head 202. The second conductive line 203 is connected to the second electrical control seat 302 through the conductive seat 210. The second electrical control seat 302 is connected to the exhaust fan 402 through the power supply seat 303. After the suction cup 404 adheres to the surface of the machine body 501, the exhaust fan 402 is powered on, drawing air from the area where the suction cup 404 is attached to the machine body 501. This air then enters the fixed base 401 through the one-way exhaust valve 403, creating a negative pressure between the suction cup 404 and the machine body 501, thus ensuring the stability of the adhesion between them. Furthermore, the operator can secure the clamping base 406 to the edge of the machine body 501 by pulling the elastic plate 405. This double fixation of the suction cup 404 and the clamping base 406 effectively ensures the stability of the equipment during the testing process. 02 The gas entering the fixed base 401 can enter the docking base 301 through the connecting groove 407. After entering the docking base 301, the gas can flow into the ventilation groove 305. The ventilation groove 305 is connected to the air jet groove 311 through the connecting groove 312, which allows the gas to be ejected from the air jet groove 311. Since the detection connector 310 is aligned with the terminal 502 at this time, the gas can be blown onto the surface of the terminal 502 after being ejected. Through this design, the equipment can automatically clean the terminal 502 during the fixing process, avoiding the presence of dust and impurities on the surface of the terminal 502 from affecting the detection accuracy. After the equipment is fixed, the push rod 306 drives the push head 307 to move, allowing the detection connector 310 to move out from inside the mounting head 304. This allows the detection connector 310 to contact the terminal 502. The second electrical control base 302 is connected to the detection connector 310 via the third conductor 309 and the push head 307. When the detection connector 310 contacts the terminal 502, the second electrical control base 302 can obtain the electrical signal data of the terminal 502 via the third conductor 309, thereby determining whether the switchgear 5 is faulty. The end of the push head 307 near the push rod 306 is equipped with... An insulating block 308 is provided to isolate the end of the electric push rod 306, which ensures the accuracy of information acquisition by the third conductive line 309. After the data acquisition is completed, the electric push rod 306 drives the push head 307 to reset, which can separate the detection connector 310 from the wiring terminal 502. In the above operation process, the staff only needs to fix and remove the equipment. There is no need to contact the live parts during the fixing and removal process. When the switch equipment 5 is not powered off during the test, or the power is turned on by someone during the test, or the switch equipment 5 has leakage, the equipment can greatly improve the safety of the staff's operation. Subsequently, after aligning the test connector 310 with the terminal 502 and fixing the device to the switch device 5, the pressing head 207 can contact the switch button 503. During the testing process of the contact component 3, the first electrical control base 204 operates, de-energizing the electromagnet 205 on the side of the pressing head 207 that contacts the switch button 503. After the electromagnet 205 is de-energized, the armature block 209 loses its magnetic attraction, and the pressing head 207 is bounced up by the return spring 206. This allows the pressing head 207 to apply force to the switch button 503. The rebound force of the return spring 206 is set to be just greater than the force applied when the switch button 503 is pressed. This allows the pressing head 207 to press the switch button 503 during its rebound. After the switch button 503 is pressed, its other end will bounce up, and the bounced end of the switch button 503 can contact the pressing head 207, which has not been displaced. If the switch button 503 is corroded or rusted... In cases such as these, the return force of the reset spring 206 cannot achieve the pressing of the switch button 503. In addition, a pressure sensor 208 is installed inside the pressing head 207. This design allows the device to determine whether the switch button 503 is faulty by judging whether the pressure sensor 208 senses pressure. Furthermore, the device can calculate the time from the de-energization of the electromagnet 205 to the pressure sensor 208 sensing pressure. If the time is too long, it can be determined that the switch button 503 is blocked. Through this design, the device can clearly and accurately determine whether the switch button 503 is faulty without manual operation, which further improves the ease of operation and safety of the device. In addition, the pressing component 2 can also work in conjunction with the contact component 3 to control the on / off state of the switch button 503 to detect the electrical signal at the terminal 502 to determine whether the switching device 5 is working properly, which further enhances the functionality of the device. Finally, because the gripping component 1, pressing component 2, contact component 3, and fixing component 4 can achieve docking and electrical connection through the interlocking and fixing of the components, the staff usually tests different models of switchgear 5 during the fault detection process. By replacing the pressing component 2, contact component 3, and fixing component 4, the equipment can be adapted to test switchgear 5 of different sizes and models, which can greatly improve the application range of the equipment. In addition, the modular design allows for retesting even when testing a single model of switchgear 5 by replacing the same type of pressing component 2 and contact component 3, thereby improving the detection accuracy of the equipment. Furthermore, the battery 102 is integrated inside the gripping component 1. When the equipment has insufficient power, simply replacing the gripping component 1 can ensure that the equipment can continue to work for a long time.
