Description

Technical Field

[0001] The invention relates to the technical field of electric power detection testing, in particular to an insulating rope testing machine. Background Art

[0002] As an important device specifically designed to test the performance of insulating ropes, the insulating rope tester plays a vital role in ensuring the safe operation of the power and related industries. In actual industrial production and operating environments, extremely stringent requirements are placed on the electrical performance of insulating ropes. The insulating rope tester is a professional testing equipment that has emerged to meet this demand. This tester has a variety of advanced testing functions, the most critical of which is the ability to accurately test the withstand voltage performance of insulating ropes. By simulating the high voltage conditions that may be encountered in actual work, a specific voltage load is applied to the insulating rope, and its response and performance at different voltage levels are observed, thereby accurately evaluating its withstand voltage capacity. This not only helps to screen insulating ropes that meet safety standards, but also ensures that they will not suffer serious safety accidents such as breakdown and discharge due to insufficient withstand voltage in actual use.

[0003] Existing insulation rope testing machines have several significant operational deficiencies. For one thing, they rely on manual loading, which not only results in low efficiency but also places operators in close proximity to the operating machine during high-voltage testing of insulation ropes, creating a high-risk environment and posing a safety hazard. Furthermore, the machines' relatively simple structure and single function limit them to testing the withstand voltage performance of insulation ropes, failing to meet more complex and diverse testing needs.

A roller block 2102 is installed at one end of the electric hanging rope push rod 2101.

[0035] Based on the above structural features and connection relationship, a Y-shaped support rod is installed on the top of the electric-controlled hanging rope push rod 2101, and a roller block 2102 is installed at the front end of the support rod to reduce friction resistance when lifting the insulating rope 9.

[0036] In this embodiment, specific reference Figure 1 and Figure 3 The recycler assembly 24 includes a telescopic push rod 2401, which is mounted on the outer wall of the mounting bracket 4. A meter counter 2402 is mounted on one end of the telescopic push rod 2401. A static clamping jaw 2403 is provided on the outer wall of the meter counter 2402. An active roller 2404 is mounted on one end of the static clamping jaw 2403. A dynamic clamping jaw 2405 is mounted on one side of the static clamping jaw 2403 and on the outer wall of the meter counter 2402. A driven roller 2406 is mounted on one end of the dynamic clamping jaw 2405. An anti-slip lever 2407 is mounted on one end of the driven roller 2406.

[0037] Based on the above structural features and the effect of the connection relationship, the recycler assembly 24 is mainly composed of a telescopic push rod 2401, a static clamping jaw 2403 and a dynamic clamping jaw 2405, an active roller 2404 and a driven roller 2406, an anti-slip lever 2407, and a meter 2402. The telescopic push rod 2401 realizes the movement change of the recovery winding position and the clamping position of the insulating rope 9. The clamping jaw is composed of a dynamic clamping jaw 2405 and a static clamping jaw 2403. The dynamic clamping jaw 2405 is A driven roller 2406 is installed, and an anti-slip lever 2407 is installed above the front end of the driven roller 2406. The anti-slip lever 2407 can be turned inward under pressure. An active roller 2404 is installed on the static clamping jaw 2403. A meter 2402 is connected to the active roller 2404 inside the clamping jaw. The meter 2402 measures the lowering length of the insulating rope 9, which can locate the position of the movable winding rod 2504 of the recovery winch 2502 and also measure the recovered length of the insulating rope 9;

[0038] In this embodiment, specific reference Figure 1 、 Figure 4 and Figure 3The recovery and bundling assembly 25 includes a bundling machine 2501 and a recovery winch machine 2502. The bundling machine 2501 is installed on the outer wall of one side of the guide rail 5, and the recovery winch machine 2502 is installed on the outer wall of the other side of the guide rail 5. Bundling belt guide plates 2503 are symmetrically installed on the outer wall of the bundling machine 2501, and a movable winding rod 2504 is arranged in a ring shape on the outer wall of the recovery winch machine 2502. Bundling belt guide grooves 2505 are symmetrically opened on one side of the movable winding rod 2504 and on the outer wall of the recovery winch machine 2502.

[0039] Among them, the console 3 is connected to the rotary actuator 7, the turntable lifting actuator 10, the test transformer 2, the input counter 18, the output counter 19, the electric rope push rod 2101, the guide rail 5, the buckle push rod 23, the pressure buckle push rod 20, the meter counter 2402 and the dynamic clamp 2405 through wires, and the connection method is electrical connection, so that the device is energized, and then the console 3 controls the rotary actuator 7, the turntable lifting actuator 10, the test transformer 2, the input counter 18, the output counter 19, the electric rope push rod 2101, the guide rail 5, the buckle push rod 23, the pressure buckle push rod 20, the meter counter 2402 and the dynamic clamp 2405 to be energized and operate. The outer wall of the guide rail 5 is sequentially provided with an initial position 51, a winding limit one 52, a winding limit two 53 and a bundling position 54, and the damper 22 is mainly composed of a pair of concave rubber rollers and an elastic energy storage component.

[0040] When the insulating rope testing machine of this scheme is in operation, the insulating rope 9 sample to be tested is placed on the winch 6, one end of the insulating rope 9 is pulled out and passed through the damper 22, and then clamped into the grounding rod 1203 of the grounding electrode assembly 12, and the grounding rod 1203 with a self-locking function is pressed in to clamp the insulating rope 9. Then, the parameters such as pole gap, test voltage, duration, leakage current limit, and sample length are filled in on the console 3, and the preparation work is completed.

[0041] The damper 22 is mainly composed of a pair of concave rubber rollers and an elastic energy storage element. When the insulating rope 9 moves through the concave roller group, it drives the rollers to rotate. The rotating rollers cause the elastic energy storage element to be subjected to force and store energy through the mechanism. At the same time, during the energy storage process, the rollers are also subjected to a reverse force, which acts on the moving insulating rope 9, making the insulating rope 9 smooth, stable and tense when moving.

[0042] The grounding electrode assembly 12 is evenly distributed on the side of the grounding turntable 11. The outer end face of the grounding electrode rod 1203 is connected to a 1 / 4 circular surface-shaped clamping disc 1209 for clamping the insulating rope 9. The outer wall of the grounding electrode rod 1203 inside the installation shell 1201 is provided with a self-locking tooth groove 1204. The self-locking tooth groove 1204 cooperates with the card key 1206 to form a self-locking function. The tail of the grounding electrode rod 1203 is installed with a connecting spring 1202. When the card key 1206 is pressurized and released, the grounding electrode rod 1203 pops out and returns to the open state under the action of the connecting spring 1202. The top end of the grounding electrode rod 1203 is installed with a ball 1210. Under the action of the buckle push rod 20, it is used to reduce the friction of the contact surface.

[0043] After starting the equipment, the equipment completes a series of actions such as hanging samples, pressure resistance, recycling, and bundling according to the automatic control program. First, the turntable lifting actuator 10 is operated to drive the high-voltage turntable 14 to move up and down, and then the set electrode gap is adjusted through the console 3. Then the console 3 controls the electric hanging rope push rod 2101 to rise, and the electric hanging rope push rod 2101 drives the insulating rope 9 to rise through the roller block 2102. When the roller block 2102 drives the insulating rope 9 to pass through the high-voltage electrode block 1503, the electric hanging rope push rod 2101 then descends to the initial position. The insulating rope 9 is in the starting position. At this time, the insulating rope 9 is stuck in the high-voltage electrode block 1503. At the same time, the elastic energy storage of the damper 22 is released, and the damper 22 retracts the insulating rope 9 to make it tense. When the insulating rope 9 is hung, the rotary actuator 7 drives the gear 8 to rotate through the meshing connection, and then the gear 8 drives the turntable lifting actuator 10 to rotate, so that the grounding turntable 11 drives the high-voltage turntable 14 to rotate to the next set of electrode points, waiting for hanging. At the same time, the input counter 18 counts the poles and repeats the hanging of the insulating rope 9 in sequence.

[0044] The test electrode disk is mainly composed of a high-voltage turntable 14, a grounding turntable 11 and a turntable lifting actuator 10. The high-voltage turntable 14 and the insulating support 13 are made of insulating material. Under the drive of the turntable lifting actuator 10, the pole gap is adjusted. The entire test electrode disk rotates at equal intervals through the rotary actuator 7 and the gear 8. The high-voltage electrode assembly 15 is evenly distributed on the side of the high-voltage turntable 14 and is cross-distributed with the grounding electrode assembly 12, so that the hanging insulating rope 9 is of equal length. When the insulating rope 9 is driven to rise by the hanging rope push rod assembly 21, the insulating rope 9 hits the bottom of the high-voltage electrode block 1503, causing the high-voltage electrode block 1503 to flip upward. After the insulating rope 9 passes through the high-voltage electrode block 1503, the high-voltage electrode block 1503 falls back to a horizontal state under the action of its own weight. Thereafter, after the hanging rope push rod assembly 21 descends, the insulating rope 9 will be hooked by the high-voltage electrode block 1503 when falling back, thereby completing the hanging action.

[0045] When testing short rope samples, they can be hung up at one time and then the voltage test can be carried out. When testing long rope samples, a segmented test mode is implemented. After the test electrode disk is fully hung, the voltage test is carried out. After the voltage test is completed, the tested part is recovered and wound, and the untested part continues to be hung up to carry out the subsequent voltage test. This cycle is repeated until the entire test sample test is completed. The high-voltage test system completes the power frequency voltage test of the test sample. The test transformer 2 outputs a high voltage, which is connected to the high-voltage electrode block 1503 through the high-voltage lead 16. The grounding rod 1203 is connected to the high-voltage tail end of the test transformer 2 through the ground wire 17. A milliammeter is installed in the loop to monitor the leakage current. The entire voltage test process is controlled and detected by the program, and the data is recorded and stored.

[0046] After the power frequency withstand voltage test is completed, the static clamping jaw 2403 and the dynamic clamping jaw 2405 of the recycler assembly 24 cooperate with each other to extend to the insulating rope 9 at the position of the shackle push rod, and the dynamic clamping jaw 2405 clamps the insulating rope 9, and then the shackle push rod 23 moves, so that one end of the shackle push rod 23 applies a thrust to the card key 1206 through the roller 1207, so that the card key 1206 and the self-locking tooth groove 1204 are disconnected, thereby causing the grounding pole 1203 to pop out and the insulating rope 9 to loosen. Then the recycler assembly 24 shrinks to its initial position, and the insulating rope 9 hung on the outer wall of the high-voltage electrode block 1503 is pulled loose. The detached insulating rope 9 is driven by the static clamping jaw 2403 and the dynamic clamping jaw 2405 in cooperation with the active roller 2404, so that the insulating rope 9 is lowered to the grounding pole 1203. The position of the movable winding rod 2504 of the recovery winch 2502 is then driven by the guide rail 5 to move the recovery winch 2502 from the initial position 51 to the winding limit position 52, and then the recovery winch 2502 drives the insulating rope 9 to rotate to perform the winding action. When the test electrode disk continues to rotate, the output counter 19 counts the poles. At the same time, the roller 1207 on the internal key 1206 of the grounding electrode assembly 12 conflicts with the shackle push rod 23 and then disengages. Under the elastic action of the connecting spring 1202, the grounding electrode rod 1203 is ejected, and the insulating rope 9 is loosened. In this way, the insulating rope 9 is detached from the test electrode disk in turn. The output counter 19 is used to record the number of shackle poles, compare the data with the input counter 18, and provide parameters for program control.

[0047] Driven by the guide rail 5, the recovery winch 2502 moves from the initial position 51 to the winding limit position 1 52 and starts the winding action. During the winding process, the recovery winch 2502 reciprocates between the winding limit position 1 52 and the winding limit position 2 53 to ensure that the insulating rope 9 is evenly wound. When the winding is completed, the recovery winch 2502 moves to the bundling position 54 and is bundled by the bundling machine 2501. The qualified products and unqualified products judged according to the pressure resistance test results are distinguished by green and yellow bundling tapes respectively.

[0048] The winch of the recovery winch 2502 is composed of a set of movable winding rods 2504 and two fixed rods, which are arranged in a triangle. The end openings of the set of movable winding rods 2504 on the top of the recovery winch 2502 are in a trumpet shape, which facilitates the smooth insertion of the insulating rope 9 when the recovery winch 2502 moves toward the winding limit 52. When the insulating rope 9 is wound and tied, the movable winding rod 2504 on the top of the recovery winch 2502 moves down to loosen the rope strands, which is convenient for the tying machine 2501 to tie. The lower part of the recovery winch 2502 is equipped with a tying belt guide groove 2 505 cooperates with the strapping guide plate 2503 on the strapping machine 2501 to form a closed loop guide groove for use by the strapping machine 2501 for strapping. The strapping machine 2501 is internally installed with two types of strapping tapes, green and yellow. When strapping is performed, the control console 3 first determines qualified products and unqualified products based on the results of the power frequency withstand voltage test, and then selects strapping tapes of different colors for strapping. Qualified products are strapped with green straps, and unqualified products are strapped with yellow straps. This solves the problem of not being able to flexibly set the parameters of the testing machine and not being able to automatically and effectively distinguish qualified products from unqualified products.
