Description

Technical Field

[0001] The present invention relates to the technical field of electric safety tool detection, and in particular, relates to a voltage withstand detection apparatus for insulating gloves. Background Art

[0002] Insulating gloves are safety articles that need to be worn by staff of the electric power system during operation and maintenance, and the insulation performance of insulating gloves requires voltage withstand detection. For current voltage withstand detection apparatuses, when detecting an insulating glove, the insulating glove is first mounted, then the water injection pipe of a water injection apparatus extends into the insulating glove, water is injected into the insulating glove until a certain water level is reached, the water injection pipe of the water injection apparatus is then withdrawn from the insulating glove, the insulating glove is immersed in a water tank, an electrode is then inserted into the insulating glove, and an electrode is also inserted into the water tank, wherein the electrode in the insulating glove is connected to a pressurizing apparatus, and the electrode in the water tank is grounded. After the pressurizing apparatus applies pressure to the electrode in the insulating glove, the voltage withstand performance of the insulating glove is tested by detecting current, and if the current does not exceed a standard, the voltage withstand performance is qualified. During the current voltage withstand test for insulating gloves, it is necessary to ensure that the part of the insulating glove above the water level is dry, so as to prevent the current from creeping through the glove opening part of the insulating glove to affect the current, and further affect the detection result.

[0003] The current voltage withstand detection apparatus has the following defects: when the water injection apparatus finishes injecting water into the insulating glove, the water injection pipe needs to be withdrawn before pressurization, and during the withdrawal process, water droplets may drip from the water injection port, which may splash after dripping onto the dry part above the water level of the insulating glove, thus affecting the detection current; and if the part is wiped clean, the wiping may not be thorough enough, or water stains may remain, which also affects the detection result. In addition, the current detection apparatus requires the water injection pipe to be withdrawn first and then the electrode to be inserted, which is relatively cumbersome to operate and reduces the detection efficiency. Summary of the Invention

[0004] In view of the above defects existing in the prior art, the present application provides a voltage withstand detection apparatus for insulating gloves, which performs water injection without withdrawing the pipe, prevents water droplets from dripping, and improves detection accuracy and efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions: A voltage withstand detection apparatus for insulating gloves includes a frame, a fixture, a dual-purpose electrode, a water injection apparatus, a pressurizing apparatus, a water tank, and a lifting mechanism; The insulating glove to be tested is suspended on the frame by a clamp. The lower end of the dual-purpose electrode extends into the insulating glove, and the upper end of the dual-purpose electrode extends above the insulating glove and is electrically connected to the pressurizing device. A connector is provided on the side of the upper end of the dual-purpose electrode. The water injection device is detachably connected to the connector. A flow channel is provided inside the dual-purpose electrode. The lower end of the flow channel extends through to the lower end of the dual-purpose electrode to form a water outlet. The connector is connected to the water outlet through the flow channel. The water tank is grounded and located below the insulating glove. The lifting mechanism is used to drive the water tank to move up and down.

[0006] Furthermore, the dual-purpose electrode includes a copper tube and an insulating component. The copper tube extends downward into the insulating glove, with its upper end extending above the insulating glove and closed. A water inlet is provided on the upper side of the copper tube. The insulating component covers the upper end of the copper tube and has a socket at the water inlet, forming the aforementioned connector.

[0007] Furthermore, the water injection device includes a controller, a water level sensor, a water pump, a water pipe, and a mounting bracket. The water pipe is a metal pipe, with one end connected to a socket and the other end connected to the water pump. The water level sensor is installed above the insulating glove to detect the water level in the insulating glove and is fixedly connected to the water pipe through the mounting bracket. The controller controls the operation of the water pump according to the water level signal.

[0008] Furthermore, the end of the water pipe is chamfered.

[0009] Furthermore, the frame includes a base plate, a top plate, columns, and a crossbeam. The top plate is fixedly installed above the base plate by multiple columns. The crossbeam is horizontally arranged between the top plate and the base plate. The upper end of the dual-purpose electrode is fixedly installed on the crossbeam. The upper end of the insulating glove is suspended on the crossbeam by a clamp.

[0010] Furthermore, a clamping structure is installed and connected on the crossbeam, and the clamping structure clamps the upper end of the dual-purpose electrode.

[0011] Furthermore, the clamp includes a clamp and a suspension rope. Multiple clamps are provided and symmetrically clamp the opening of the insulating glove. The clamps are suspended from the frame by the suspension rope.

[0012] Furthermore, the lifting mechanism includes a nut, a screw, and a motor. The nut is fixedly installed on the side of the water tank, the screw is rotatably connected to the frame and driven by the motor, and the screw and nut are threadedly engaged.

[0013] Furthermore, the aforementioned nuts and screws are provided on both opposite sides of the water tank, and the screws are connected by a transmission mechanism, with the motor driving one of the screws.

[0014] This application has the following beneficial effects: 1. The dual-purpose electrode combines the functions of a water pipe and an electrode. After filling with water, it can be directly powered on for testing without being pulled out, eliminating the need to pull out the pipe and insert the electrode. This also avoids water droplets from splashing onto the dry part of the insulating gloves when pulling out the pipe, resulting in high testing accuracy and efficiency. 2. The water outlet of the dual-purpose electrode is located near the lower end of the insulating glove. When water is injected, the water level rises steadily from bottom to top without splashing. The part of the insulating glove above the water level remains dry. 3. The upper end of the copper pipe fitting is covered with an insulating component, and only the lower end, which is submerged in water, is exposed and conductive, preventing high-voltage leakage. This ensures high testing safety and accurate test results. 4. The non-contact water level sensor detects the water level inside the insulated glove in real time, and the controller automatically controls the start and stop of the water pump according to the water level signal, so that the water level is accurate and controllable and the degree of automation is high; 5. The ends of the water pipes are chamfered to ensure smooth connection and disconnection with the connector socket, and easy insertion and removal; 6. The cuffs of the insulating gloves are symmetrically clamped and suspended, allowing the gloves to hang naturally. The dual-purpose electrodes do not contact the inner wall of the gloves to prevent current bypass and ensure accurate test results. 7. The lifting mechanism uses a screw and nut drive to lift the water tank, ensuring smooth lifting, reliable self-locking, and a stable water surface without splashing. 8. Both sides of the water tank are equipped with screws and nuts, which are synchronously driven by the transmission mechanism. The multi-point support and uniform force distribution ensure stable lifting and lowering of the water tank and prevent it from tilting. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. The drawings only show components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] like Figures 1 to 8 As shown in the figure, an insulating glove withstand voltage testing device provided by an embodiment of the present invention includes a frame 1, a clamp 2, a dual-purpose electrode 3, a water injection device, a pressurizing device, a water tank 4, and a lifting mechanism 5. The insulating glove 6 to be tested is suspended on the frame 1 by the clamp 2. The lower end of the dual-purpose electrode 3 extends into the insulating glove 6, and the upper end of the dual-purpose electrode 3 extends above the insulating glove 6 and is electrically connected to the pressurizing device. A connector 7 is provided on the upper side of the dual-purpose electrode 3. The water injection device is detachably connected to the connector 7. A flow channel 8 is provided inside the dual-purpose electrode 3. The lower end of the flow channel 8 extends through to the lower end of the dual-purpose electrode 3 to form a water outlet. The connector 7 is connected to the water outlet through the flow channel 8. The water tank 4 is grounded and is located below the insulating glove 6. The lifting mechanism 5 is used to drive the water tank 4 to move up and down.

[0027] The frame 1 is a rigid frame structure that provides stable support for the entire machine. The clamp 2 can take various forms, as long as it can connect to the upper opening of the insulating glove 6 and allow for its suspension. The dual-purpose electrode 3 serves as both a water pipe and an electrode; its upper end connects to a pressurization device for introducing high-voltage electricity, and it can also be connected to or disconnected from a water injection device. The water tank 4 is located below the insulating glove 6 and is used to hold the test water. The water tank 4 is grounded, forming the low-voltage side of the test circuit.

[0028] The testing method in this embodiment is as follows. First, wipe the outside of the dual-purpose electrode 3 to ensure it is completely dry, preventing residual moisture from wetting the cuff of the insulating glove when it is put on. Second, place the insulating glove 6 to be tested on the lower end of the dual-purpose electrode 3, and suspend the insulating glove 6 on the frame 1 using the clamp 2. Third, connect the water injection device to the connector 7. At this time, the pressurization device is completely disconnected to prevent electric shock. Then, water from the water injection device flows into the flow channel 8 through the connector 7 and exits from the outlet into the insulating glove 6, slowly filling the insulating glove 6. In this embodiment, the lower end of the dual-purpose electrode 3 is close to the bottom of the insulating glove 6. During the water injection process, the water level will submerge the lower end of the dual-purpose electrode 3 and then slowly rise upwards. The outlet remains below the water surface, and the water flows out from below the water surface, preventing splashing and ensuring that the glove cuff above the water level is completely dry.

[0029] Once the water level reaches the preset height, stop the water injection device, then separate the device from connector 7. During separation, wrap connector 7 with absorbent material (such as paper towels) before pulling out the hose to prevent excess water droplets from falling near connector 7 and thus avoid splashing. Water tank 4 is filled with water, and then slowly rises under the action of lifting mechanism 5, so that the water in tank 4 covers the lower end of insulating glove 6, meaning the lower end of insulating glove 6 slowly submerges in the water tank 4. When the water level in tank 4 is approximately level with the water level in insulating glove 6, lifting mechanism 5 stops. The water levels inside and outside insulating glove 6 are approximately level, and the water pressure inside and outside the glove is balanced. Insulating glove 6 will not deform due to the pressure difference, and the part of the glove opening exposed above the water surface remains dry to prevent current creepage from the opening, ensuring the accuracy of the test results.

[0030] After the pressurizing equipment is powered on, the voltage is slowly increased until it reaches the test voltage. The pressurizing equipment has a built-in current detection function. The test voltage is maintained for 1-3 minutes, the specific time depending on the testing requirements. Then, the current is measured. If the current does not exceed the threshold, the withstand voltage performance is reliable; if the current exceeds the threshold, the withstand voltage performance is unqualified. During the test, the current flows from the dual-purpose electrode 3 through the water inside the insulating glove 6, the insulating layer of the insulating glove 6, and the water in the water tank 4 to the ground. The insulation performance of the insulating glove 6 can be judged by detecting the magnitude of the leakage current. After the test is completed, the pressurizing equipment is turned off, and the water tank 4 moves downward to reset under the action of the lifting mechanism 5. Then, the insulating glove 6 is replaced, and the next round of testing can be carried out.

[0031] In this application, the dual-purpose electrode 3 has both water pipe and electrode functions, making the testing steps simpler. Simply put on the insulating gloves 6, and after filling with water, disconnect the water filling equipment before applying pressure for testing. There is no need to pull out the dual-purpose electrode 3. After directly applying power to the dual-purpose electrode 3, subsequent testing can be carried out, eliminating the need for tube removal and avoiding the dripping and splashing problems caused by tube removal. The test results are accurate and the testing efficiency is high.

[0032] In one implementation, the dual-purpose electrode 3 includes a copper tube 9 and an insulating component 10. The copper tube 9 extends downward into the insulating glove 6, with its upper end extending above the insulating glove 6 and closed. A water inlet 11 is provided on the upper side of the copper tube 9. The insulating component 10 covers the upper end of the copper tube 9 and has a socket at the water inlet 11, forming the aforementioned connector 7.

[0033] The copper fitting 9 is made of pure copper, which has good electrical conductivity. The inner side of the copper fitting 9 forms the aforementioned flow channel 8. The pipe wall of the copper fitting 9 serves both electrical conductivity and water flow functions, resulting in a compact structure. The closed end of the copper fitting 9 can be sealed with a welded sealing plate, ensuring that water can only flow out from the lower outlet and will not overflow from the upper end. The insulating component 10 is made of plastic and covers the copper fitting 9, serving as insulation to prevent leakage. The lower end of the copper fitting 9 is exposed outside the insulating component 10 and is immersed in water inside the insulating glove 6 during testing, allowing high voltage to be introduced into the water, ensuring reliable conductivity. The insulating component 10 covers the portion of the copper fitting 9 above the water surface. Because the copper fitting 9 requires high voltage, the insulating component 10 prevents the portion above the water surface from discharging to surrounding objects or being accidentally touched by personnel, further improving safety and testing accuracy. The insulating component 10 has a protruding tubular structure on one side, which connects to the inlet 11, acting as a socket structure for easy connection to water injection equipment. The insulating component 10 can be fixed to the upper end of the copper tube 9 by injection molding, fitting, or bonding. In addition, the lower end of the copper tube 9 can be rounded or chamfered to prevent scratching the inner wall of the insulating glove 6 when it is put on, thus protecting the insulating glove 6.

[0034] In one implementation, the water injection device includes a controller, a water level sensor 12, a water pump, a water pipe 13, and a mounting bracket 14. The water pipe 13 is a metal pipe, with one end connected to a socket and the other end connected to the water pump. The water level sensor 12 is mounted above the insulating glove 6 to detect the water level in the insulating glove 6, and is fixedly connected to the water pipe via the mounting bracket. The controller controls the operation of the water pump based on the water level signal.

[0035] The water level sensor 12 uses a non-contact water level sensor such as radar or ultrasonic, which does not require contact with water, avoids disturbing the water, and provides accurate and reliable detection results. The mounting bracket 14 serves to support the water level sensor 12, fixing it to the end of the water pipe and allowing it to move synchronously with the pipe. The detection end of the water level sensor 12 faces downwards, towards the water surface inside the insulating glove 6, to detect the water level height inside the insulating glove 6 in real time. Once the preset height is reached, the controller shuts off the water pump, stopping water injection. Water level control is precise and highly automated, requiring no manual monitoring. The controller can be a PLC or microcontroller. The water pump can be a small water pump similar to that used in household aquariums; the flow rate does not need to be high, just enough to provide stable water injection. A low flow rate ensures a smooth water flow and a steady rise in the water level, further preventing splashing and ensuring the dryness of the portion of the insulating glove 6 above the water level. The water pump's inlet is connected to the water storage container, and its output is connected to the water pipe 13. Water pipe 13 is a metal pipe with a certain degree of rigidity. When it is fitted with the socket, it is easy to insert and position. It is not easy to bend or deform even after repeated insertion and removal, and it has good durability.

[0036] As one implementation method, the end of the water pipe 13 is provided with a chamfer. The chamfer is set at the end where the water pipe 13 connects to the socket. When inserting, the chamfer plays a guiding role, which facilitates the connection and disconnection of the water pipe 13 between the joints 7, making the insertion and removal smooth. At the same time, it reduces the scratching of the inner wall of the socket, extends the service life of the socket, ensures the sealing effect of the connection, and prevents water leakage at the joint 7 when water is injected.

[0037] In one implementation, the frame 1 includes a base plate 15, a top plate 16, columns 17, and a crossbeam 18. The top plate 16 is fixedly installed above the base plate 15 by multiple columns 17. The crossbeam 18 is horizontally arranged between the top plate 15 and the base plate 16. The upper end of the dual-purpose electrode 3 is fixedly installed on the crossbeam 18, and the upper end of the insulating glove 6 is suspended on the crossbeam 18 by a clamp 2.

[0038] The base plate 15, with its large area, is placed on the ground to provide stable support for the entire machine, preventing it from shaking or tipping over during testing. Four columns 17 can be installed, positioned at the four corners of the base plate 15, providing stable support and even stress distribution. A testing space is formed between the top plate 16 and the base plate 15, resulting in a rational and compact arrangement of components. The horizontal beam 18 is horizontally positioned, ensuring that the dual-purpose electrode 3 and the insulating glove 6 suspended on it remain vertical and hang naturally. The dual-purpose electrode 3 is located in the center of the insulating glove 6, with a gap between it and the inner wall of the insulating glove 6, preventing contact and improving the accuracy of the test results. The horizontal beam 18 and the columns 17 can be fixedly connected by bolts or welding. The height of the horizontal beam 18 is adapted to the length of the insulating glove 6. The horizontal beam 18 can be made of insulating material or have its surface insulated to further enhance safety.

[0039] As one implementation method, a clamping structure 19 is installed on the crossbeam 18, which clamps the upper end of the dual-purpose electrode 3. The clamping structure 19 can be composed of two semi-circular clamping blocks, which are locked with bolts, clamping the outer side of the insulating part 10 at the upper end of the dual-purpose electrode 3. This ensures a secure fixation without direct contact with the live copper pipe 9, making it safe and reliable. Using the clamping structure 19 for fixation facilitates the installation and removal of the dual-purpose electrode 3, making it easy to replace or clean the electrode and ensuring that the surface of the electrode 3 is clean and dry before each test. An anti-slip pad can also be provided on the inner side of the clamping structure 19 to increase friction and prevent the dual-purpose electrode 3 from slipping during testing, further enhancing the fixation.

[0040] In one implementation, the clamp 2 includes a clamp 20 and a suspension rope 21. Multiple clamps 2 are provided, symmetrically clamping the opening of the insulating glove 6, and the clamps 20 are suspended from the frame 1 by the suspension rope 21.

[0041] In this embodiment, two clamps 20 are used. Both the clamps 20 and the suspension ropes 21 are made of insulating material to prevent electric shock, ensure safety, and not affect the detection current. The two clamps 20 clamp the left and right sides of the sleeve opening, respectively, and then the sleeve is suspended from the frame 1 by two suspension ropes 21, specifically, the suspension ropes 21 are connected to the crossbeam 18. The symmetrical clamping ensures that the insulating glove 6 is subjected to uniform force, maintains a natural hanging state, preserves the sleeve opening shape, and keeps the dual-purpose electrode 3 always located in the middle of the insulating glove 6, without contacting the inner wall of the insulating glove 6, preventing current bypass and ensuring accurate detection results. The clamp openings of the clamps 20 can be padded to prevent damage to the sleeve opening of the insulating glove 6 during clamping. The length of the suspension ropes 21 is adjustable, making it easy to adjust the suspension height of the insulating glove 6 to adapt to the length of the dual-purpose electrode 3.

[0042] In one implementation, the lifting mechanism 5 includes a nut 22, a screw 23, and a motor. The nut 22 is fixedly installed on the side of the water tank 4, and the screw 23 is rotatably connected to the frame 1 and driven by the motor. The screw 23 and the nut 22 are threadedly engaged.

[0043] Both ends of the screw 23 are rotatably connected to the frame 1 via bearing seats, ensuring stable support and smooth rotation. A servo motor can be used, with precise controllable speed and stroke, guaranteeing smooth lifting, uniform speed, and accurate positioning of the water tank 4. The screw 23 and nut 22 work together to form a screw-nut transmission, which is self-locking, preventing the water tank 4 from sliding down at any height, ensuring reliable positional stability and good safety. A guide rail can be installed between the column 17 and the side of the water tank 4, allowing the water tank 4 to move up and down along the rail, further improving the stability of its movement and preventing tilting or swaying, thus avoiding water splashing due to surface fluctuations. A grating ruler can also be installed on the side of the column 17 to monitor the height of the water tank 4 in real time, improving lifting accuracy and ensuring the water level in the water tank 4 is accurately level with the water level in the insulating glove 6, preventing the water tank 4 from rising too high and submerging the opening of the insulating glove 6, or rising too low and affecting the detection results. The water tank 4 moves smoothly up and down, and the water in the water tank 4 moves smoothly with the water tank 4. The water surface will not fluctuate greatly, and the water will not splash onto the dry part of the insulating glove 6 above the water level, ensuring the accuracy of the test results.

[0044] As one implementation, the water tank 4 is provided with nuts 22 and screws 23 on both opposite sides. The screws 23 are connected by a transmission mechanism 24, and a motor drives one of the screws 23. This means the water tank 4 has multi-point support, resulting in even force distribution and improved stability during vertical movement, preventing tilting or jamming. The transmission mechanism 24 can be implemented by mounting pulleys on the screws 23 and then driving them via belts. This means that driving one screw 23 will cause the others to rotate synchronously, resulting in good synchronization and a simple structure. The transmission mechanism 24 can also use synchronous belt drives or sprocket and chain drives. In this embodiment, the use of pulley and belt drives is only a preferred implementation method. One motor can drive both screws 23 to move up and down synchronously, saving costs and ensuring the water tank 4 remains horizontal.

[0045] The present invention will be further described below in conjunction with the working process of this embodiment: Before the test, water is filled into the water tank 4 and the water tank 4 is grounded. Then, the outside of the dual-purpose electrode 3 is wiped to ensure that its surface is dry. The insulating glove 6 to be tested is put on the lower end of the dual-purpose electrode 3. The left and right sides of the opening of the insulating glove 6 are symmetrically clamped with two clips 20 and suspended on the crossbeam 18 by the hanging rope 21.

[0046] During water injection, the pressurizing equipment remains disconnected. The water pipe 13 of the water injection equipment is connected to the socket of the connector 7. The controller controls the water pump to work. Water flows from the water pipe 13, the inlet 11, and the flow channel 8 into the insulating glove 6 from the outlet. The water level rises steadily from bottom to top without splashing. The sleeve part of the insulating glove 6 above the water level remains dry. The water level sensor 12 detects the water level in real time. After the preset water level is reached, the controller shuts off the water pump. Then, the connector 7 is wrapped with absorbent material to separate the water pipe 13 from the connector 7, preventing residual water droplets near the connector 7 from falling.

[0047] During the pressure test, the lifting mechanism 5 drives the water tank 4 to rise slowly, so that the water in the water tank 4 submerges the lower end of the insulating glove 6. The pressure test is stopped when the water level in the water tank 4 is basically level with the water level in the insulating glove 6. The pressure equipment is powered on, and the pressure is slowly increased to the test voltage and maintained for a specified time. The leakage current is detected, and the detected current is compared with the threshold to determine whether the pressure resistance performance of the insulating glove 6 is qualified.

[0048] After the test is completed, the pressurization equipment is turned off, the lifting mechanism 5 drives the water tank 4 to descend and reset, and the insulated gloves 6 are replaced before the next round of testing. Throughout the test, the dual-purpose electrode 3 does not need to be removed from the insulated gloves 6. After water is added, it can be directly powered on for testing, eliminating the need for unplugging and inserting the electrode. This avoids the problems of dripping or splashing water when unplugging the electrode, resulting in accurate test results and high testing efficiency.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
